Frequently Asked Questions (FAQ)

Q: Can 1933192 be used as a direct replacement for 1546931-3?

A: Yes. The 1933192 maintains identical mechanical dimensions (3 positions, 5.00mm pitch, vertical orientation, 0.138" tail length, 0.079" insulation height), termination style (solder), and mounting type (through hole). The 1933192 exceeds the electrical specifications of the 1546931-3 with a 16 A UL current rating compared to 12 A, and both parts maintain 300 V UL voltage rating and UL94 V-0 flammability compliance.

Q: Can OP0300000000G be used as a direct replacement for 1546931-3?

A: Yes. The OP0300000000G maintains identical mechanical dimensions, termination style, and mounting type. The OP0300000000G provides a 15 A UL current rating, exceeding the 12 A specification of the 1546931-3, while maintaining 300 V UL voltage rating and UL94 V-0 compliance. The OP0300000000G additionally specifies an operating temperature range of -40°C to 115°C.

Q: What are the key compatibility parameters for these terminal block headers?

A: Compatibility is determined by: number of positions (3), pitch (0.197" or 5.00mm), header orientation (vertical), contact tail length (0.138" or 3.50mm), insulation height (0.079" or 2.00mm), termination style (solder), mounting type (through hole), and flammability rating (UL94 V-0). All three parts match these parameters exactly.

Q: Are there differences in housing material between these parts?

A: The 1546931-3 specifies Polyamide (PA66), Nylon 6/6 housing. The 1933192 specifies Polyamide (PA), Nylon housing. The OP0300000000G specifies Thermoplastic housing. All materials meet UL94 V-0 flammability requirements and are functionally equivalent for this application category.

Q: Do all parts have the same RoHS compliance status?

A: Yes. All three parts—1546931-3, 1933192, and OP0300000000G—are ROHS3 compliant. The 1933192 and OP0300000000G additionally carry REACH Unaffected status.

Q: What is the difference in current ratings between these parts?

A: The 1546931-3 is rated for 12 A (UL). The 1933192 is rated for 16 A (UL) and 12 A (IEC). The OP0300000000G is rated for 15 A (UL) and 12 A (IEC). All parts maintain 300 V UL voltage rating. The higher current ratings of the substitute parts provide additional design margin without requiring circuit modification.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical mechanical dimensions, pitch, orientation, and contact geometry ensure that these parts are mechanically and electrically interchangeable at the board level. No PCB redesign or component repositioning is required.
