|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Explanation: |
Brand |
Series |
Factory Code 2RRCM - Right-angle flanged header; this breakdown applies to the 002A configuration |
Pitch 5.08 - 5.08mm |
Poles 02–24 - 2–24 poles, using two digits |
Pole Suffix |
Colour 4 - Green, as specified by the 4002A model |
Customer Code 002A - Fixed suffix for this configuration |
TB27 2RRCM headers have a single straight contact row at 5.08mm pitch and are available with 2–24 contacts. The housing includes end fixing positions. Select the complete model, since the standard version and 4002A version have different contact materials and IEC current ratings.
| Model | Configuration | Contact material | General IEC rating |
|---|---|---|---|
| TB27-2RRCM/5.08 | Standard right-angle PCB header | Red copper, tin plated | 20A, 320V |
| TB27-2RRCM/5.08-4002A | 4002A right-angle PCB header | Brass, tin plated | 16A, 320V |
Check mating contact geometry, keying and fixing dimensions against the intended counterpart. Exact mating part numbers and fixing thread sizes are unspecified.

4002A also carries a general UL-standard notation of 16A, 300V without a specified use group; this does not extend the use-group B or D limits above. Its dielectric withstand test is 2000VAC for 1 minute. A dielectric test value for the standard model and certificate file numbers are unspecified.

| Field | Meaning |
|---|---|
| Base model | TB27-2RRCM/5.08 |
| Pole field P | 02–24P |
| Colour legend | 1 grey; 2 blue; 3 black; 4 green; 5 orange; 6 red; 7 transparent; 8 yellow; 9 white |
| 4002A suffix | Colour 4, green, with customer suffix 002A; its drawing shows Y002A, where Y is the colour field |
| General screw-head field | 0 slot; 1 cross |
| General screw-clamping field | 0 screw down; 1 screw up |
| General standard-product field | 0A |
The general legend applies to the wider terminal range. Its 02–99 pole field does not extend these models beyond 2–24 contacts, and screw-clamp fields do not define wire termination on these PCB headers. Illustrated products are green; not every colour and suffix combination is specified.
P is the number of contacts, from 2 to 24. Dimensional formulas give millimetres. The following outline references are shown for both models.
| Dimension | Standard and 4002A |
|---|---|
| Contact pitch | 5.08mm |
| Overall flange length | 5.08(P+2)mm |
| Fixing-centre span | 5.08(P+1)mm |
| Housing depth reference | 12.00mm |
| Front housing section | 8.40mm |
| Side section reference | 9.70mm |
| Contact section reference | 1.00mm |
| Solder-tail projection | 3.50±0.30mm |
| 4002A PCB dimension | Value |
|---|---|
| Hole pitch | 5.08mm |
| First-to-last hole span | 5.08(P−1)mm |
| Hole diameter | Ø1.40mm |
| Longitudinal end-to-first-hole reference | 7.60mm |
| Body boundary to contact-row reference | 8.00mm |
The 4002A attachment includes the PCB layout. PCB hole size and edge references for the standard version are unspecified here; the common outline does not establish an identical PCB layout.
These apply where the 4002A drawing does not give an individual tolerance.
