4DB-P107-04 Equivalent & Substitute Parts

Part Overview

The 4DB-P107-04 is a 4-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This through-hole terminal block features 0.325" (8.26mm) pitch spacing, dual-wall barrier construction, and screw termination on the top with PC pin connections on the bottom. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 4DB-P107-04 is determined by strict equivalence in the following core parameters:

• Terminal Block Type: Barrier Block construction required
• Circuit Count: 4 circuits
• Pitch Spacing: 0.325" (8.26mm) mandatory for PCB and mechanical compatibility
• Row Configuration: Single row
• Termination Style: Screw top termination with PC pin bottom termination
• Barrier Construction: Dual-wall (2 Wall) barrier type
• Mounting: Through-hole configuration
• Flammability Compliance: UL94 V-0 rating

The Curtis Industries 325110-04-0 meets all core substitution criteria. Variations in current rating, voltage rating, wire gauge range, insulation material, and screw finish do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The Curtis Industries 325110-04-0 is a direct substitute for the discontinued 4DB-P107-04 based on mechanical and electrical compatibility. Both parts share identical pitch spacing, circuit count, row configuration, termination methods, and barrier construction. Both achieve UL94 V-0 flammability compliance and ROHS3 certification.

The 325110-04-0 maintains the same operating temperature rating of 105°C and MSL rating of 1 (Unlimited). The substitute part is currently in active production status with 831 pieces in stock, providing supply continuity for applications previously using the 4DB-P107-04.

Applications requiring the full 20A current rating of the original part should confirm that the 15A rating of the substitute meets circuit requirements. Applications operating at voltages below 150V are fully compatible with the substitute's 300V rating. Wire gauge compatibility exists for gauges 14-22 AWG; applications using 12 AWG wire require evaluation against the substitute's 14-22 AWG specification.

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325110-04-0 be used as a direct replacement for the 4DB-P107-04 in existing designs?

A: Yes, for applications where the current requirement does not exceed 15A and wire gauge is 14-22 AWG. The pitch spacing, circuit count, mounting configuration, and termination methods are identical, ensuring mechanical and electrical compatibility on PCBs designed for the original part.

Q: What is the primary difference between these two barrier block connectors?

A: The main differences are current rating (20A vs. 15A), voltage rating (150V vs. 300V), wire gauge range (12-22 AWG vs. 14-22 AWG), and insulation material (Polyamide vs. Polypropylene). The 325110-04-0 offers higher voltage capability but lower current capacity.

Q: Are both parts compliant with environmental and safety standards?

A: Yes. Both the 4DB-P107-04 and 325110-04-0 are ROHS3 compliant, achieve UL94 V-0 flammability rating, and carry MSL rating of 1 (Unlimited). Both operate at 105°C maximum temperature.

Q: What packaging is available for the Curtis Industries substitute?

A: The 325110-04-0 is supplied in bulk packaging with 831 pieces currently in stock.

Q: If my application requires 12 AWG wire termination, can I use the Curtis Industries part?

A: The 325110-04-0 supports wire gauges 14-22 AWG. Applications requiring 12 AWG wire termination must use the original 4DB-P107-04 or identify an alternative part with 12-22 AWG wire gauge specification.

Q: Is the 325110-04-0 suitable for applications requiring 20A current?

A: No. The 325110-04-0 is rated for 15A maximum current. Applications requiring 20A current must use the original 4DB-P107-04 or identify an alternative part with 20A current rating.
