Molex 0010883042 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0010883042 is an active-status rectangular connector header designed for through-hole, right-angle mounting applications. This 4-position, 2-row connector with 0.100" (2.54mm) pitch serves general-purpose, automotive, lighting, medical, and telecommunications applications. Given the availability of alternative connector solutions with comparable electrical and mechanical characteristics, substitute parts may be evaluated for specific application requirements where compatibility parameters align.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0010883042 is determined by alignment of the following critical parameters:

• Mating Pitch: 0.100" (2.54mm) — must match exactly for PCB footprint compatibility
• Connector Type: Header, Breakaway configuration
• Contact Type: Male Pin
• Mounting Style: Through Hole, Right Angle
• Termination Method: Solder
• Contact Material: Copper Alloy
• Insulation Material Classification: Polyester or Thermoplastic base
• Flammability Rating: UL94 V-0 minimum
• Row Configuration: 2-row arrangement with 0.100" row spacing

The identified substitute part TE Connectivity AMP Connectors 4-103324-0 shares these core parameters. However, differences exist in position count (80 vs. 4), contact finish composition (Tin-Lead vs. Tin), insulation material type (Thermoplastic vs. Polyester Glass Filled), and regulatory compliance status (RoHS non-compliant vs. ROHS3 Compliant). These differences must be evaluated against specific application constraints.

Engineering Selection Recommendations

Primary Selection: The Molex 0010883042 remains the recommended choice for new designs and active production. This part maintains active product status, ROHS3 compliance, and current manufacturing support.

Substitute Consideration: The TE Connectivity 4-103324-0 presents significant compatibility constraints that limit its practical substitution value:

• Position Count Mismatch: The 80-position configuration versus the 4-position requirement creates a fundamental incompatibility with existing PCB layouts and mechanical assemblies designed for the Molex part.
• Regulatory Compliance: RoHS non-compliance status introduces supply chain and regulatory risk for applications subject to RoHS requirements.
• Product Status: Obsolete classification indicates discontinued manufacturing and limited availability for long-term supply assurance.
• Contact Finish Composition: Tin-Lead finish differs from the Tin finish of the primary part, affecting solderability characteristics and environmental exposure considerations.

For applications requiring a substitute connector with identical position count and compatible electrical/mechanical characteristics, alternative sources should be evaluated against the core parameter set defined in this document.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 4-103324-0 be used as a direct replacement for the Molex 0010883042?

A: No. While both connectors share the same mating pitch (0.100"), row spacing, and mounting style, the 80-position configuration of the TE part is incompatible with PCB designs and assemblies engineered for the 4-position Molex connector. Position count is a non-negotiable substitution parameter.

Q: What are the critical parameters that determine connector substitutability?

A: Mating pitch, connector type, contact type, mounting style, termination method, row configuration, and row spacing must match exactly. Position count, contact finish, and insulation material type are also critical for mechanical and electrical compatibility.

Q: Does the Tin-Lead contact finish of the TE part affect compatibility?

A: Contact finish composition affects solderability and environmental resistance but does not prevent physical mating. However, mixing Tin and Tin-Lead finishes in the same assembly may introduce galvanic corrosion risk and is not recommended for long-term reliability.

Q: Is the TE Connectivity part suitable for RoHS-regulated applications?

A: No. The TE Connectivity 4-103324-0 is RoHS non-compliant. Applications subject to RoHS requirements must use ROHS3-compliant alternatives such as the Molex 0010883042.

Q: What is the significance of the "Obsolete" product status for the TE part?

A: Obsolete status indicates the part is no longer manufactured. This creates supply availability risk and limits long-term sourcing options. Active-status parts are preferred for new designs and ongoing production.

Q: Can insulation material differences (Polyester Glass Filled vs. Thermoplastic) affect performance?

A: Insulation material affects mechanical strength, temperature stability, and flammability characteristics. Polyester Glass Filled provides enhanced rigidity and thermal performance compared to standard Thermoplastic. Material selection should align with application environmental and mechanical requirements.
