Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 4-644631-2 are qualified based on the following critical parameters that determine functional interchangeability:

Core Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 12
• Number of Rows: 1
• Pitch - Mating: 0.156" (3.96mm)
• Mounting Type: Through Hole
• Termination: Solder
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Contact Shape: Square
• Style: Board to Cable/Wire or Board to Board

Compliance Parameters:

• Material Flammability Rating: UL94 V-0 or equivalent
• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The identified substitute parts Molex 0026604120 and Molex 1718131012 satisfy all core matching criteria and compliance requirements. Variations in contact finish, insulation material, and dimensional tolerances within acceptable ranges do not preclude substitution when the primary part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 4-644631-2 (Primary Part)

The TE Connectivity 4-644631-2 remains the primary specification when available. This part carries RoHS Compliant status, UL94 V-0 flammability rating, and operates across the full temperature range of -55°C to 105°C. The gold-plated mating contacts provide enhanced corrosion resistance and contact reliability. Current inventory of 857 pieces supports immediate availability for production requirements.

Molex 0026604120 (Substitute Option)

The Molex 0026604120 qualifies as a direct substitute when TE Connectivity 4-644631-2 is unavailable. This part maintains all critical functional parameters including 12-position, 0.156" pitch, through-hole solder termination, and shrouded friction-lock design. The part carries ROHS3 Compliant status and UL94 V-0 flammability rating, matching the primary part's compliance profile. Tin-plated mating contacts differ from the primary part's gold finish but remain suitable for general purpose and industrial applications. Inventory availability of 11,140 pieces provides extended sourcing capability. The slightly increased overall contact length (0.720" versus 0.700") and reduced insulation height (0.446" versus 0.545") fall within acceptable mechanical tolerances for standard through-hole PCB applications.

Molex 1718131012 (Substitute Option)

The Molex 1718131012 qualifies as an alternative substitute when both primary and first-choice substitute parts are unavailable. This part maintains all critical functional parameters and carries ROHS3 Compliant status. The UL94 V-2 flammability rating represents a lower classification than the primary part's UL94 V-0 rating and should be evaluated against specific application flammability requirements. Gold-plated mating contacts match the primary part's contact finish. The reduced contact post length (0.093" versus 0.125") and overall contact length (0.671" versus 0.700") require verification for compatibility with existing mating connectors and PCB hole patterns. Inventory availability of 4,675 pieces supports sourcing when other options are exhausted.

Frequently Asked Questions (FAQ)

Q: Can Molex 0026604120 be used as a direct replacement for TE Connectivity 4-644631-2?

A: Yes. Both parts share identical core specifications: 12-position, 0.156" pitch, through-hole solder termination, shrouded friction-lock design, and square contact geometry. Both carry UL94 V-0 flammability rating and RoHS compliance. The primary difference is contact finish (tin versus gold on mating contacts), which does not prevent functional substitution in general purpose and industrial applications.

Q: What are the key differences between the two Molex substitute options?

A: Molex 0026604120 features tin-plated mating contacts and UL94 V-0 flammability rating, matching the primary part's compliance level. Molex 1718131012 features gold-plated mating contacts but carries UL94 V-2 flammability rating. Contact post lengths differ: 0026604120 at 0.140" and 1718131012 at 0.093" compared to the primary part's 0.125". These dimensional variations may affect compatibility with specific mating connectors.

Q: Are there any compliance concerns when substituting these parts?

A: All three parts carry RoHS compliance status (RoHS Compliant or ROHS3 Compliant) and Moisture Sensitivity Level 1 (Unlimited). The primary consideration is the UL94 V-2 rating on Molex 1718131012 versus UL94 V-0 on the primary part and Molex 0026604120. Applications requiring UL94 V-0 certification should use the primary part or Molex 0026604120.

Q: How do dimensional variations affect substitution?

A: The contact length and insulation height variations between parts fall within acceptable ranges for standard through-hole PCB applications. However, applications with tight mechanical constraints or specific mating connector requirements should verify dimensional compatibility before substitution. The reduced post length on Molex 1718131012 (0.093" versus 0.125") may affect engagement depth with certain mating connectors.

Q: What is the difference between board-to-cable and board-to-board style designations?

A: The primary part specifies board-to-cable/wire style, while both Molex substitutes specify board-to-board or cable style. This designation reflects the connector's intended mating interface. All three parts function identically in through-hole solder termination and friction-lock fastening, making them interchangeable for applications using either mating style.

Q: Can these parts be used interchangeably in automotive applications?

A: The Molex parts list automotive applications in their specification. However, the primary TE Connectivity part does not explicitly list automotive applications. Automotive applications should verify that the selected substitute meets all relevant automotive qualification and reliability standards beyond the general compliance parameters provided.
