The IC390 family combines socket strips and the IC390D framed configuration. Select a model by pitch, body form and termination geometry before choosing pin and clip plating. Pin plating and the internal contact-clip finish are separate ordering fields.

The following six finish codes apply independently to both pin and clip plating on IC390A, C, D, F, G, H, I and J. IC390B and E use their own codes below.
| Code | Finish |

| 1 | Tin 150µin |
| 2 | Tin 200µin |
| 3 | Gold flash |
| 4 | Gold 3µin |
| 5 | Gold 10µin |
| 6 | Gold 15µin |
Mounting codes are V for vertical through-hole, R for right-angle through-hole and S for SMT. Choose pin and clip finishes independently from codes 1–6.
| Mounting | Body and height | Terminal geometry |
|---|---|---|
| Vertical | 3.00mm body height; 7.50mm overall; widths 2.54mm single row and 5.08mm dual row | Ø0.50mm ±0.05mm pin; Ø1.32mm ±0.1mm terminal-body reference |
| Right angle | 3.00mm body depth; 2.54mm single-row and 5.08mm dual-row body width | 5.60mm mounting reference; 3.20mm lower projection; Ø0.46mm terminal, with Ø0.51mm also marked on the outer dual-row terminal |

Pitch and dual-row spacing are 2.54mm, with ±0.1mm where marked. Vertical strip length is P × 2.54mm ±0.5mm; right-angle and SMT length is P × 2.54mm without a separately marked overall tolerance. The dual-row SMT formula N/2 × 2.54mm counts total contacts in N.
Clip type B has four fingers. Pin plating T1 is full tin; clip plating is F6 for 3µin gold or T1 for tin.
Single-row width is 2.20mm and dual-row width is 4.40mm. Both use 2.80mm housing height, 7.40mm overall height and Ø0.43mm pins. Longitudinal pitch and dual-row spacing are 2.00mm ±0.10mm. End offset is 1.00mm, and strip length is P × 2.0mm; the dual-row drawing expresses this as 2.0 × N/2 with N as total contacts.
Pin-length code 1 specifies 10.00mm overall length. Select pin and clip finishes independently with codes 1–6. Both single and dual rows have a 7.00mm housing section and Ø0.60mm PCB pins.
Pitch and dual-row spacing are 2.54mm. Body width is 2.54mm for a single row and 5.08mm for dual rows. Overall length is P × 2.54mm; end-contact span is (P − 1) × 2.54mm.
Width codes N and W select row spacing C of 7.62mm and 15.24mm respectively. Pin length F is 4.20mm. Pin and clip finishes use independent codes 1–6.
Values below are in millimetres. A is overall length, B is end-contact span, C is row spacing and D is outside frame width. Pitch is 2.54mm ±0.05mm. Housing height is 3.00mm and overall height is 4.20mm.

| 40 | W | 51.00 | 48.26 | 15.24 | 17.78 |
Pin and clip plating are independent. Each uses 6 for full tin, 8 for full gold flash, C for full gold 3µin or A for full gold 10µin.
Body width is 2.54mm, housing/shoulder section is 2.55mm, overall height is 4.82mm ±0.20mm and the lower projection reference is 1.90mm. Pin diameter is Ø0.80mm ±0.05mm. Pitch is 2.54mm ±0.05mm; strip length is P × 2.54mm ±0.40mm and end-contact span is (P − 1) × 2.54mm ±0.20mm.
Both models offer contact type 1 or 2 and L codes 1–8. Pin and clip finishes are independently selected with codes 1–6. IC390F lists single and dual rows; IC390G lists single rows. The G drawing includes dual-row geometric references without a corresponding dual-row ordering range.

| 5 | 10.00mm |
| 6 | 11.00mm |
| 7 | 12.00mm |
| 8 | 14.60mm |
L is measured from the socket top to the start of the projecting PCB pin; the pin extends a further 3.20mm. Both types have Ø0.50mm PCB pins and a 3.00mm housing section. Type 2 adds an Ø1.00mm extended terminal section and a 4.20mm upper contact reference. Single-row body width is 2.54mm; the dual-row reference is 5.08mm with 2.54mm row spacing. Strip length is P × 2.54mm ±0.5mm.
Mounting codes are R for right angle and S for SMT. Profile code 420 is 4.20mm and 700 is 7.00mm. Both profiles are dimensioned for right-angle mounting; the SMT outline shows the 7.00mm profile. Pin and clip finishes use independent codes 1–6.
| Mounting and profile | Body and terminal references |

Pitch and dual-row spacing are 2.00mm, with ±0.1mm where marked. Strip length is P × 2.0mm ±0.5mm. The dual-row SMT formula N/2 × 2.0mm ±0.5mm uses N as total contacts.
Contact codes 1, 2 and 3 select the following terminal outlines. Pin and clip finishes use independent codes 1–6. Listed contact counts are 6, 8, 14, 16, 18, 20, 24, 28, 32 and 40.
| Contact type | Length references | PCB pin diameter |
|---|---|---|
| 1 | 7.40mm overall | Ø0.45mm |
| 2 | 8.50mm to pin shoulder plus 3.20mm projecting pin | Ø0.53mm |
| 3 | 10.00mm to pin shoulder plus 4.00mm projecting pin | Ø0.53mm |
All three show 2.50mm body width, 3.00mm housing height and a 4.20mm upper contact reference. Pitch is 1.778mm and strip length is P × 1.778mm ±0.2mm.
