Molex 0022432040 Equivalent & Substitute Parts

Part Overview

The Molex 0022432040 is a 4-position individual wires connector with IDC (Insulation Displacement Contact) termination, designed for 24-26 AWG stranded or solid conductors. This connector features through-hole, press-fit mounting on PCBs with a 0.098" (2.50mm) pitch configuration and closed-end design with tin contact finish.

The 0022432040 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022432040 is determined by the following critical parameters:

Connector Type: Must be Individual Wires configuration
Position Count: Must be 4 positions
Pitch Specifications: Cable pitch and board-side pitch must both be 0.098" (2.50mm)
Row Configuration: Must be single row (1 row)
Mounting Method: Must support through-hole, press-fit installation
Termination Type: Must use IDC (Insulation Displacement Contact) technology
End Configuration: Must be closed end design
Wire Gauge Compatibility: Must accommodate 24-26 AWG conductors (stranded or solid)

The JST Sales America Inc. 04DB-6S meets all substitution criteria. While it specifies 24-28 AWG (extending the upper range to 28 AWG), it maintains full compatibility with the 24-26 AWG range of the original part. The connector maintains identical pitch, position count, mounting type, and IDC termination method.

Engineering Selection Recommendations

The JST 04DB-6S is a direct functional substitute for the Molex 0022432040 based on electrical and mechanical parameter alignment. The substitute part is in active production status, ensuring ongoing availability compared to the obsolete original part.

Two compliance considerations require evaluation:

RoHS Compliance: The original Molex 0022432040 is ROHS3 compliant. The JST 04DB-6S is RoHS non-compliant. If your application or market requires RoHS compliance, this substitution may not be acceptable without regulatory review.
Contact Finish: The original part uses tin finish; the substitute uses tin-lead finish. Both are tin-based finishes suitable for IDC applications. Tin-lead finish is an older standard; verify compatibility with your soldering and environmental specifications.

The wire gauge specification of the 04DB-6S (24-28 AWG) encompasses the original specification (24-26 AWG), confirming mechanical and electrical compatibility for all intended wire sizes.

Frequently Asked Questions (FAQ)

Q: Can the JST 04DB-6S be used as a direct replacement for the Molex 0022432040 in existing PCB designs?

A: Yes, from a mechanical and electrical standpoint. Both connectors share identical pitch (0.098"), position count (4), mounting method (through-hole press-fit), and IDC termination. PCB footprints are compatible. However, verify RoHS compliance requirements for your application, as the substitute is RoHS non-compliant.

Q: What is the difference between the wire gauge specifications?

A: The original Molex part specifies 24-26 AWG; the JST substitute specifies 24-28 AWG. The substitute's extended range fully includes the original specification, ensuring compatibility with all wire sizes originally supported.

Q: Does the color difference (Natural vs. White) affect functionality?

A: No. Color is a cosmetic attribute only and does not affect electrical or mechanical performance. The difference reflects manufacturing standards between Molex and JST.

Q: What does "Individual Wires" connector type mean?

A: This connector accepts individual wire conductors terminated with IDC contacts, rather than a pre-assembled cable or ribbon cable assembly. Each wire is inserted and terminated individually into the connector body.

Q: Are there any soldering or assembly differences when using the JST 04DB-6S?

A: No. Both connectors use identical through-hole, press-fit mounting. Assembly procedures remain unchanged. Verify that your soldering profile is compatible with the tin-lead contact finish of the substitute part.

Q: What does "Closed End" design mean?

A: Closed end indicates that the connector body has a sealed or enclosed design at the wire entry end, preventing accidental contact with internal terminals and providing strain relief for the wire bundle.
