Molex 0010894123 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0010894123 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 12-position, 2-row connector with 0.100" (2.54mm) pitch serves general purpose, automotive, lighting, medical, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design flexibility permits component interchange based on compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict alignment of the following parameters:

• Mating Pitch: 0.100" (2.54mm) — must match exactly for mechanical compatibility
• Contact Type: Male Pin — determines mating interface
• Mounting Configuration: Through Hole, Right Angle — establishes PCB mounting method
• Termination Method: Solder — defines connection to PCB
• Contact Finish - Mating: Gold — ensures signal integrity and corrosion resistance
• Contact Finish - Post: Tin — specifies solder joint interface
• Insulation Material Flammability: UL94 V-0 — meets safety requirements
• RoHS Compliance: ROHS3 or RoHS Compliant — satisfies environmental regulations

The substitute part TE Connectivity AMP Connectors 9-102975-0 meets all critical substitution criteria. While it differs in position count (80 vs. 12) and insulation material composition (Thermoplastic vs. Polyester, Glass Filled), these differences do not preclude substitution when the application permits use of a higher-position-count connector or when mechanical envelope constraints are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and satisfy RoHS and ECCN compliance requirements. The Molex 0010894123 is the primary specification. The TE Connectivity 9-102975-0 qualifies as a substitute based on matching mating pitch, contact configuration, mounting method, and termination specifications.

Selection between these parts depends on application-specific requirements:

• Position Count: The Molex part provides 12 positions; the TE part provides 80 positions. Applications requiring exactly 12 positions should use the Molex part. Applications permitting higher position counts may use the TE part if PCB layout accommodates the larger footprint.

• Insulation Material: The Molex part uses Polyester, Glass Filled insulation; the TE part uses Thermoplastic insulation. Both meet UL94 V-0 flammability requirements. Material selection depends on thermal and mechanical environment specifications.

• Operating Temperature and Current Rating: The TE part specifies -65°C ~ 105°C operating temperature and 3A current rating. The Molex part does not specify these parameters. When operating temperature or current requirements are defined, verify the selected part meets those specifications.

• Packaging: The Molex part is supplied in Tube packaging; the TE part is supplied in Bulk packaging. Procurement and handling procedures may differ accordingly.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 9-102975-0 directly replace the Molex 0010894123 in all applications?

A: Direct replacement is possible when the application permits use of an 80-position connector in place of a 12-position connector, and when the Thermoplastic insulation material is acceptable for the operating environment. PCB layout must accommodate the larger connector footprint. Verify that the mating connector or cable assembly is compatible with the TE part's physical dimensions and contact configuration.

Q: What are the critical parameters that must match for substitution?

A: Mating pitch (0.100" / 2.54mm), contact type (Male Pin), mounting method (Through Hole, Right Angle), termination (Solder), contact finish (Gold mating, Tin post), and flammability rating (UL94 V-0) must match. These parameters ensure mechanical and electrical compatibility.

Q: Does the difference in insulation material affect performance?

A: Both materials meet UL94 V-0 flammability requirements. Polyester, Glass Filled and Thermoplastic differ in thermal and mechanical properties. Selection depends on the specific operating environment, thermal cycling requirements, and mechanical stress conditions of the application.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The Molex part is ROHS3 Compliant; the TE part is RoHS Compliant. Both have MSL 1 (Unlimited) moisture sensitivity. Both are classified under HTSUS 8536.69.4040.

Q: What should be considered when switching from the Molex part to the TE part?

A: Verify PCB layout accommodates the 80-position connector footprint. Confirm the mating connector or cable assembly is compatible with the TE part. Review operating temperature (-65°C ~ 105°C) and current rating (3A) specifications to ensure they meet application requirements. Evaluate insulation material compatibility with the thermal and mechanical environment.

Q: Is the higher position count of the TE part a disadvantage?

A: The higher position count is not inherently a disadvantage. It permits greater design flexibility for future expansion or multi-function applications. However, it requires larger PCB space and may increase component cost. Use the 12-position Molex part if the application requires exactly 12 positions and space is constrained.
