Parameter Comparison

Engineering Selection Recommendations

4DB-P107-05 (Primary Selection): The 4DB-P107-05 remains the primary component choice for applications requiring the full specified current rating of 20A at 150V. This part is manufactured by TE Connectivity AMP Connectors and maintains Active product status with full ROHS3 compliance. The component supports wire gauges from 12-22 AWG, providing maximum flexibility for conductor sizing. Polyamide insulation material with UL94 V-0 flammability rating ensures compliance with safety standards.

325110-05-0 (Substitute Selection): The 325110-05-0 manufactured by Curtis Industries is functionally equivalent for applications where current requirements do not exceed 15A. This substitute provides higher voltage rating capability (300V versus 150V) and maintains identical mechanical interface specifications including 0.325" pitch, dual-wall barrier construction, and through-hole mounting. The component is ROHS3 compliant and Active product status. Wire gauge accommodation is limited to 14-22 AWG, excluding 12 AWG conductors. Polypropylene insulation with UL94 V-0 rating provides equivalent safety performance.

Selection Criteria:

• Use 4DB-P107-05 when current requirements reach or exceed 15A
• Use 325110-05-0 when current requirements are limited to 15A or below and 12 AWG wire gauge is not required
• Both parts are suitable for 105°C operating temperature environments
• Both parts maintain equivalent electrical isolation through dual-wall barrier construction
• Both parts are Active products with current manufacturing support

Frequently Asked Questions (FAQ)

Q: Can 325110-05-0 be used as a direct replacement for 4DB-P107-05?

A: The 325110-05-0 is functionally equivalent for applications where the maximum current requirement does not exceed 15A. The substitute part maintains identical mechanical interface specifications, pitch spacing, circuit count, and mounting configuration. However, the current rating difference (15A versus 20A) must be evaluated against application requirements. If the application requires 20A current capacity, the 4DB-P107-05 is the appropriate selection.

Q: What is the difference in wire gauge compatibility?

A: The 4DB-P107-05 accommodates wire gauges from 12-22 AWG, while the 325110-05-0 accommodates 14-22 AWG. Applications requiring 12 AWG conductor termination must use the 4DB-P107-05. For applications using 14-22 AWG conductors, both parts are compatible.

Q: Are the insulation materials interchangeable?

A: The 4DB-P107-05 uses Polyamide (PA) nylon insulation, while the 325110-05-0 uses Polypropylene (PP) insulation. Both materials achieve UL94 V-0 flammability rating and operate at 105°C. The materials are functionally interchangeable from a safety and thermal perspective. Material selection may be driven by specific application environmental requirements not specified in this reference.

Q: Do both parts maintain the same voltage rating?

A: No. The 4DB-P107-05 is rated for 150V, while the 325110-05-0 is rated for 300V. The substitute part provides higher voltage capability. For applications operating at or below 150V, both parts are suitable. For applications exceeding 150V, the 325110-05-0 provides additional voltage margin.

Q: Are both parts RoHS compliant?

A: Yes. Both the 4DB-P107-05 and 325110-05-0 are ROHS3 compliant and maintain Active product status with current manufacturing support.

Q: What is the significance of the dual-wall barrier construction?

A: The 2 Wall (Dual) barrier type provides electrical isolation between adjacent circuits. Both the 4DB-P107-05 and 325110-05-0 feature identical dual-wall barrier construction, ensuring equivalent circuit isolation performance.

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

A: Yes, provided the application current requirements do not exceed 15A and wire gauge requirements fall within the 14-22 AWG range. Both parts feature identical 0.325" pitch spacing, PC pin bottom termination, and through-hole mounting configuration, allowing direct mechanical and electrical substitution within these parameter constraints.
