Molex 0010894182 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0010894182 is an 18-position, right-angle header connector with 0.100" (2.54mm) pitch designed for through-hole board-to-board or cable applications. This connector features a breakaway design with unshrouded construction and solder termination. The part is currently active in production with 870 units in stock. Alternative components may be required due to supply constraints, design revisions, or specific application requirements where substitute connectors meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

The 3M 929838-02-09-RK qualifies as a direct substitute for the Molex 0010894182 based on the following critical parameters:

• Connector Configuration: Both parts are 18-position, 2-row headers with 0.100" (2.54mm) mating pitch and row spacing
• Mounting and Termination: Both use through-hole, right-angle mounting with solder termination
• Contact System: Both feature male pin contacts with square contact shape and copper alloy material
• Electrical Compliance: Both meet UL94 V-0 flammability requirements and are RoHS compliant
• Mechanical Compatibility: Both are unshrouded, board-to-board style connectors with push-pull fastening

Substitution is valid where the mechanical envelope and electrical performance requirements align with these core parameters.

Parameter Comparison

Engineering Selection Recommendations

Both connectors meet the core functional requirements for 18-position, 2.54mm pitch header applications with identical mechanical and electrical compatibility at the mating interface. Selection between these parts should be based on:

• PCB Design Constraints: The 3M 929838-02-09-RK has significantly longer post length (0.405" vs. 0.110"), which affects PCB thickness compatibility and solder joint accessibility. Verify post length requirements against your PCB design specifications.

• Contact Finish Requirements: The Molex part features gold-plated mating contacts, while the 3M substitute uses tin plating. Gold plating provides enhanced corrosion resistance and lower contact resistance in low-current applications. Tin plating is suitable for standard industrial applications with adequate current capacity (2.5A per the 3M specification).

• Insulation Material: The Molex part uses polyester with glass reinforcement; the 3M part uses PCT. Both materials meet UL94 V-0 flammability requirements. PCT offers superior moisture resistance and dimensional stability.

• Compliance and Certification: Both parts are RoHS compliant and meet UL94 V-0 standards. The 3M part provides explicit operating temperature (-40°C to 105°C) and current rating (2.5A) specifications.

• Supply and Availability: The Molex part has 870 units in stock; the 3M substitute has 1100 units available. Selection may depend on delivery timeline and inventory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3M 929838-02-09-RK directly replace the Molex 0010894182 in existing designs?

A: Direct replacement is mechanically and electrically compatible at the mating interface due to identical pitch, row spacing, contact type, and mounting configuration. However, the significantly longer post length on the 3M part (0.405" vs. 0.110") requires verification against your PCB thickness and solder joint design. Physical testing of the assembly is recommended before production implementation.

Q: What is the impact of different contact finishes (gold vs. tin)?

A: Gold plating on the Molex part provides superior corrosion resistance and lower contact resistance, making it preferable for low-current or high-reliability applications. Tin plating on the 3M part is suitable for standard industrial use with adequate current capacity. The 3M part is rated for 2.5A continuous current. Select based on your application's current requirements and environmental exposure.

Q: Are there differences in insulation material performance?

A: The Molex part uses polyester with glass reinforcement; the 3M part uses PCT (polycyclohexylenedimethylene terephthalate). Both meet UL94 V-0 flammability standards. PCT offers superior moisture absorption resistance and dimensional stability under thermal cycling. For applications with high humidity or temperature cycling, the 3M part may provide better long-term performance.

Q: What is the significance of the post length difference?

A: The 3M part has a post length of 0.405" compared to 0.110" for the Molex part. This affects the depth of solder joint penetration and requires PCB design verification. Longer posts provide greater mechanical strength but require thicker PCBs or modified assembly processes. Confirm your PCB thickness and solder joint requirements before substitution.

Q: Are both parts suitable for automotive and medical applications?

A: The Molex part explicitly lists automotive, medical, and telecommunications applications. The 3M part does not specify applications in the provided data. Both meet UL94 V-0 flammability requirements and RoHS compliance. For automotive or medical use, verify that the 3M part meets any additional qualification or certification requirements specific to your application standards.

Q: What is the difference in moisture sensitivity classification?

A: The Molex part is classified as MSL 1 (Unlimited), indicating no moisture sensitivity concerns. The 3M part is listed as Not Applicable, suggesting it does not require moisture sensitivity classification. This difference does not impact substitution for standard applications but may be relevant for high-reliability or long-term storage scenarios.
