4DB-P107-10 Equivalent & Substitute Parts

Part Overview

The 4DB-P107-10 is a 10-circuit barrier block connector manufactured by TE Connectivity AMP Connectors. This terminal block features a 0.325" (8.26mm) pitch with screw-based top termination and PC pin bottom termination, rated for 20A at 150V. The component is actively produced and maintains full RoHS compliance with UL94 V-0 flammability certification.

Substitute parts are identified when equivalent terminal blocks share the same core functional characteristics: barrier block type, circuit count, pitch spacing, termination method, and mounting configuration. Substitution becomes necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical parameters of alternative manufacturers' offerings.

Substitute Part Grouping Explanation

Substitution eligibility for the 4DB-P107-10 is determined by strict alignment with the following critical parameters:

Mechanical Compatibility Requirements:

Terminal block type must be barrier block
Circuit count must equal 10
Pitch spacing must be 0.325" (8.26mm)
Top termination must be screw-based
Bottom termination must be PC pin
Mounting configuration must be through hole
Single-row layout required
Dual-wall barrier configuration required

Electrical Compatibility Considerations:

Current rating of substitute must not be less than the application requirement
Voltage rating of substitute must not be less than the application requirement
Wire gauge acceptance range must accommodate the conductor sizes in use
Operating temperature rating must support the thermal environment

Compliance Requirements:

UL94 V-0 flammability rating required
RoHS compliance status must be active (RoHS3 or equivalent)
Moisture sensitivity level must be 1 (Unlimited)

The Curtis Industries 325110-10-0 meets all critical mechanical parameters and compliance requirements, making it a valid substitute when electrical parameters of the application do not exceed the substitute's ratings.

Engineering Selection Recommendations

Primary Part Selection (4DB-P107-10): The 4DB-P107-10 is the specified component and remains the first choice when availability permits. This part is actively produced by TE Connectivity AMP Connectors with confirmed inventory of 999 pieces. Full RoHS compliance and UL94 V-0 certification are established. The 20A current rating and 150V voltage rating define the baseline electrical performance envelope.

Substitute Part Selection (325110-10-0): The Curtis Industries 325110-10-0 is a valid mechanical and electrical substitute when the following conditions are met:

Current Requirement: The application circuit current must not exceed 15A. If the design requires the full 20A capacity of the primary part, this substitute is not suitable.
Wire Gauge Requirement: If 12 AWG conductors are specified, the substitute's 14-22 AWG range does not accommodate this size. Applications limited to 14-22 AWG are compatible.
Compliance Status: The substitute maintains ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements equivalent to the primary part.
Voltage Margin: The substitute's 300V rating exceeds the primary part's 150V rating, providing additional voltage margin in applications operating below 150V.
Availability: The substitute has confirmed inventory of 735 pieces, supporting supply continuity when primary part lead times extend beyond project requirements.

Selection Logic:

Use 4DB-P107-10 for applications requiring 20A capacity or 12 AWG wire accommodation
Use 325110-10-0 for applications with current requirements ≤15A and wire gauge limited to 14-22 AWG
Both parts are suitable for 105°C operating environments and applications requiring UL94 V-0 compliance

Frequently Asked Questions (FAQ)

Q: Can the Curtis Industries 325110-10-0 be used as a direct replacement for the 4DB-P107-10?

A: The Curtis Industries part is mechanically and functionally compatible when the application electrical parameters do not exceed the substitute's ratings. The substitute is suitable for applications with maximum current of 15A and wire gauge between 14-22 AWG. If the design requires 20A capacity or uses 12 AWG conductors, the primary part must be used.

Q: What is the primary difference between these two parts?

A: The critical difference is current rating. The 4DB-P107-10 is rated for 20A, while the 325110-10-0 is rated for 15A. Both parts share identical mechanical configuration, pitch spacing, circuit count, termination method, and mounting type. The Curtis Industries part provides higher voltage rating (300V vs. 150V), which is advantageous in high-voltage applications but does not affect substitution suitability for standard 150V designs.

Q: Are both parts RoHS compliant?

A: Yes. The 4DB-P107-10 carries RoHS compliance certification, and the 325110-10-0 carries ROHS3 compliance certification. Both meet current regulatory requirements for hazardous substance restrictions.

Q: What wire gauges are compatible with each part?

A: The 4DB-P107-10 accepts 12-22 AWG conductors. The 325110-10-0 accepts 14-22 AWG conductors. Applications using 12 AWG wire require the primary part. Applications limited to 14-22 AWG can use either part.

Q: Do both parts have the same flammability rating?

A: Yes. Both the 4DB-P107-10 and 325110-10-0 carry UL94 V-0 flammability certification, meeting the same fire safety standards.

Q: Can I use the Curtis Industries part in a 20A circuit?

A: No. The 325110-10-0 is rated for maximum 15A continuous current. Using this part in a 20A circuit exceeds its electrical rating and creates a safety hazard. The 4DB-P107-10 must be used for 20A applications.

Q: Are the mounting configurations identical?

A: Yes. Both parts use through-hole mounting with PC pin bottom termination and screw-based top termination. PCB footprints are compatible due to matching pitch spacing (0.325") and single-row configuration.

Q: What is the operating temperature range for both parts?

A: Both parts are rated for 105°C maximum operating temperature. This rating applies to both the primary and substitute parts.

Q: Is the barrier configuration the same on both parts?

A: Yes. Both parts feature 2-wall (dual) barrier configuration, providing equivalent electrical isolation between circuits.
