Molex 0901310934 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0901310934 is an active-status vertical rectangular connector header designed for through-hole mounting applications. This C-Grid III 90131 series component features 28 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-cable/wire interconnections in automotive and general-purpose applications. The connector employs unshrouded male pin contacts with gold-plated mating surfaces and tin-plated posts, terminated via solder with push-pull fastening.

Substitute parts become necessary when the primary component reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative connector configurations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0901310934 is determined by the following critical parameters:

• Mating Pitch: 0.100" (2.54mm) - fundamental to mechanical and electrical compatibility
• Contact Type: Male Pin headers
• Mounting Configuration: Through-hole solder termination with push-pull fastening
• Row Configuration: 2-row arrangement with 0.100" row spacing
• Contact Finish: Gold-plated mating surfaces for reliable electrical connection
• Insulation Material Properties: UL94 V-0 flammability rating for safety compliance

The identified substitute part TE Connectivity AMP Connectors 4-103240-0 shares the core mating pitch, contact type, mounting method, and row configuration. However, this substitute exhibits significant parameter deviations in position count (80 vs. 28), contact geometry, insulation material composition, and compliance status that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (Molex 0901310934): This connector maintains active product status with ROHS3 compliance, making it the preferred selection for new designs and applications requiring regulatory adherence. The component is currently in stock with 847 units available.

Substitute Component (TE Connectivity 4-103240-0): This part carries obsolete product status and RoHS non-compliance due to tin-lead post plating. The 80-position configuration exceeds the 28-position requirement of the primary component, introducing potential design incompatibilities. The thermoplastic insulation material differs from the polyester glass-filled specification of the primary part. Selection of this substitute is limited to legacy system maintenance or applications where regulatory compliance is not mandated.

The geometric parameter deviations—including contact length, insulation height, and overall connector dimensions—require mechanical fit verification in existing PCB layouts and mating connector designs before implementation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103240-0 directly replace the Molex 0901310934 in new designs?

A: No. The substitute part carries obsolete status and RoHS non-compliance. Additionally, the 80-position configuration does not match the 28-position requirement. The Molex 0901310934 is the appropriate selection for active designs.

Q: What are the critical compatibility parameters between these connectors?

A: Both connectors share 0.100" (2.54mm) mating pitch, 2-row configuration with identical row spacing, male pin contact type, through-hole solder termination, push-pull fastening, and UL94 V-0 flammability rating. These parameters establish the foundation for potential substitution consideration.

Q: How do the contact geometry differences affect connector performance?

A: The TE Connectivity substitute exhibits shorter mating contact length (0.230" vs. 0.266") and reduced insulation height (0.090" vs. 0.098"). These dimensional variations may affect mating depth, contact engagement force, and mechanical stability in existing PCB designs. Verification against specific application requirements is necessary.

Q: Why is the position count difference significant?

A: The substitute provides 80 positions versus the 28-position requirement. This excess capacity introduces unnecessary board space consumption and potential crosstalk considerations. Position-specific applications require exact matching to avoid design complications.

Q: What compliance implications exist for the substitute part?

A: The TE Connectivity 4-103240-0 is RoHS non-compliant due to tin-lead post plating and carries obsolete product status. Applications subject to RoHS directives or requiring long-term component availability must utilize the active-status Molex 0901310934.

Q: Are the insulation material differences functionally significant?

A: The primary component uses polyester glass-filled insulation while the substitute employs thermoplastic material. Both achieve UL94 V-0 flammability rating. Material composition differences may affect thermal stability, moisture absorption, and mechanical properties under specific environmental conditions.
