Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0428910139 is determined by strict alignment of the following critical parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Pitch - Mating: 0.156" (3.96mm)
• Number of Positions: 4
• Number of Rows: 1
• Mounting Type: Through Hole
• Shrouding: Shrouded - 1 Wall
• Fastening Type: Friction Lock
• Termination: Solder
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant

The TE Connectivity AMP Connectors part number 3-644615-4 meets all mandatory substitution criteria. Both connectors share identical mating pitch, position count, row configuration, mounting methodology, shrouding design, fastening mechanism, termination type, and regulatory compliance status. Variations in contact length, insulation height, contact material composition, and contact finish specifications represent acceptable engineering tolerances within the rectangular connector category and do not preclude functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0428910139 and TE Connectivity 3-644615-4 maintain active product status with full manufacturing support. Both components achieve ROHS3 compliance and UL94 V-0 flammability certification, meeting contemporary regulatory requirements for industrial and consumer applications. The TE Connectivity part provides documented operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC), offering explicit performance boundaries for thermal and electrical design verification. Selection between these parts should be based on supply availability, cost considerations, and specific application requirements within the documented performance envelope. No additional testing or verification is required for functional equivalence in standard rectangular connector applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-644615-4 directly replace the Molex 0428910139 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.156"), position count (4), row configuration (1), mounting type (through hole), shrouding design (shrouded - 1 wall), fastening mechanism (friction lock), and termination method (solder). The connectors are functionally equivalent for standard board-to-cable applications.

Q: What are the differences in contact post length between these parts?

A: The Molex 0428910139 features a contact post length of 0.140" (4.66mm), while the TE Connectivity 3-644615-4 has a contact post length of 0.125" (3.18mm). This 0.015" (0.38mm) difference represents a minor variation within acceptable tolerances for through-hole solder termination and does not affect mating compatibility.

Q: Are both connectors RoHS compliant?

A: Yes. Both the Molex 0428910139 and TE Connectivity 3-644615-4 are ROHS3 compliant and meet current environmental and regulatory standards for electronic component manufacturing.

Q: What is the operating temperature range for these connectors?

A: The TE Connectivity 3-644615-4 specifies an operating temperature range of -55°C to 105°C. The Molex 0428910139 does not provide an explicit operating temperature specification in the available documentation.

Q: Do these connectors have different contact materials?

A: Yes. The Molex 0428910139 uses brass contacts, while the TE Connectivity 3-644615-4 uses copper alloy contacts. Both materials provide adequate electrical conductivity and corrosion resistance for standard connector applications. Contact finish specifications (gold for Molex mating surface, tin for TE Connectivity mating surface) provide additional protection and ensure reliable electrical performance.

Q: Are both connectors suitable for automotive applications?

A: The Molex 0428910139 is explicitly listed for automotive applications. The TE Connectivity 3-644615-4 is designated for general purpose and industrial applications. Application suitability should be confirmed against specific automotive qualification requirements if automotive use is required.
