The 333 family contains a screw connection terminal and a straight PCB pin header. Both use 3.5mm pitch and a single row of 2–24 poles. Select the component by its complete model and structure; conductor preparation data apply to the 333K terminal only.
| Model | Component | Pitch | Poles | Connection arrangement |
|---|---|---|---|---|
| TB11-333K/3.5 | Wire protector screw terminal | 3.5mm | 2–24 | Single row of conductor connections with top-access screws |
| TB71-333J/3.5 | PCB pin header | Single straight row of through-hole solder pins |
IEC values apply at overvoltage category III and pollution degree 2. UL use-group ratings remain separate for each component.
| Model | IEC current / voltage | Rated impulse voltage | UL group B | UL group C | UL group D |
|---|---|---|---|---|---|
| TB11-333K/3.5 | 10A / 250V | 2.5kV | 8A / 300V | Not specified | Not specified |
| TB71-333J/3.5 | 2kV | 8A / 300V |
| Parameter | TB11-333K/3.5 |
|---|---|
| IEC conductor cross-section | 1.0–2.5mm² |
| UL wire range | 28–16AWG |
| Clamping screw | M2 |
| Tightening torque | 0.2N·m |
| Stripping length | 5mm |
The IEC cross-section is specified without separate solid, flexible or ferrule subranges. The 333J header uses solder pins and has no screw connection wire range.
