Molex 0712310015 Equivalent & Substitute Parts

Part Overview

The Molex 0712310015 is a rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This 9-position, single-row connector features a 0.165" (4.20mm) mating pitch and shrouded 4-wall design with locking ramp fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0712310015 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins for through-hole mounting
• Position Count: 9-position single-row configuration
• Shrouding & Fastening: Shrouded 4-wall design with locking ramp mechanism
• Contact Material & Finish: Brass with tin plating for mating surfaces
• Insulation Properties: Glass-filled polymer with UL94 V-0 flammability rating
• Compliance: ROHS3 compliance and REACH unaffected status

The TE Connectivity AMP Connectors part 1877285-9 qualifies as a substitute based on matching connector type, position count, shrouding configuration, fastening mechanism, contact material, and compliance certifications. Variations in mating pitch (0.156" vs. 0.165"), insulation material composition, and contact dimensions represent design differences that must be evaluated within specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1877285-9 is an active product with equivalent functional classification and compliance certifications. Selection between the Molex 0712310015 and TE Connectivity 1877285-9 requires evaluation of mating pitch tolerance in the receiving connector interface. The 0.24mm pitch difference (4.20mm vs. 3.96mm) represents a dimensional variance that may or may not be accommodated by existing mating receptacles, depending on connector design specifications.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial, medical, and telecommunications applications. The TE Connectivity part offers the advantage of active product status and documented operating temperature range (-25°C to 105°C) with specified current and voltage ratings (7.5A at 250VAC).

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1877285-9 directly replace the Molex 0712310015 in existing designs?

A: Direct replacement depends on mating connector pitch tolerance. The 0.24mm pitch difference requires verification that receiving connectors accommodate both 4.20mm and 3.96mm pitch headers. Physical fit testing is necessary before production implementation.

Q: What is the significance of the insulation material difference between these parts?

A: The Molex part uses polyester while the TE Connectivity part uses polybutylene terephthalate (PBT). Both are glass-filled and rated UL94 V-0. Material selection affects thermal stability and chemical resistance; application-specific environmental conditions determine suitability.

Q: Are both parts suitable for the same applications?

A: Both parts are specified for general purpose, industrial, and telecommunications applications. The TE Connectivity part additionally lists lighting applications. Compliance certifications are equivalent, but operating temperature range documentation is available only for the TE Connectivity part.

Q: What packaging considerations apply to these connectors?

A: The Molex 0712310015 is listed as obsolete with 974 pieces in stock. The TE Connectivity 1877285-9 is active with 3089 pieces available in bulk packaging. Procurement planning should account for product status and inventory availability.

Q: How do contact dimensions affect substitution suitability?

A: Contact length variations (mating: 0.209" vs. 0.306"; post: 0.154" vs. 0.142") and overall contact length differences (0.567" for TE part) may affect insertion force, retention, and electrical performance. These dimensional differences require evaluation within specific circuit board layout and mating connector specifications.
