Molex 0010894207 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010894207 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This unshrouded, 20-position header with 2-row configuration operates at 0.100" (2.54mm) pitch and features gold-plated mating contacts with tin-plated posts. The component is specified for automotive, general purpose, lighting, medical, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent configurations.

Substitute Part Grouping Explanation

The Samtec Inc. MTSW-110-09-L-D-430-RA qualifies as a substitute for the Molex 0010894207 based on the following critical parameters:

• Connector Type & Contact Configuration: Both parts are male pin headers with identical 20-position, 2-row unshrouded configurations
• Pitch Specification: Both maintain 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting & Termination: Both are through-hole, right-angle, solder-terminated connectors
• Contact Finish: Both feature gold-plated mating contacts and tin-plated posts
• Insulation Material & Flammability: Both use polyester glass-filled insulation with UL94 V-0 rating
• Compliance: Both are ROHS3 compliant and REACH unaffected with MSL 1 rating

Differences in contact length, contact material composition, and operating temperature specifications do not preclude substitution when mechanical fit and electrical performance requirements are satisfied by the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0010894207 and Samtec MTSW-110-09-L-D-430-RA are active-status products with identical compliance certifications: ROHS3 compliant, REACH unaffected, and UL94 V-0 flammability rating. Selection between these parts should be based on specific application requirements regarding contact length, post length, and contact material composition. The Samtec substitute provides a longer mating contact (0.430" vs. 0.320") and a shorter post (0.090" vs. 0.110"), which may be advantageous in applications requiring deeper mating engagement or reduced PCB stack height. Both parts maintain equivalent electrical and mechanical compatibility for standard 0.100" (2.54mm) pitch header applications.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine substitution compatibility between these parts?

A: The critical parameters are: 20-position, 2-row configuration; 0.100" (2.54mm) mating pitch and row spacing; through-hole, right-angle, solder-terminated mounting; unshrouded male pin header design; and gold-plated mating contacts with tin-plated posts. Both parts satisfy these requirements.

Q: How do the contact length differences affect substitution?

A: The Samtec part features a longer mating contact (0.430" vs. 0.320") and shorter post (0.090" vs. 0.110"). These dimensional differences may impact mechanical fit in applications with specific PCB thickness or mating depth requirements. Verify that the substitute part's contact geometry is compatible with the receiving connector or socket in your application.

Q: Are there material composition differences between the parts?

A: Yes. The Molex part uses copper alloy contacts while the Samtec part uses phosphor bronze contacts. Both materials are suitable for solder termination and gold plating. The phosphor bronze in the Samtec part may provide different mechanical properties and spring characteristics.

Q: What is the difference between "Breakaway" and "Cuttable" connector types?

A: Both designations indicate that the header can be separated into individual pins or smaller groups. "Breakaway" and "Cuttable" are functionally equivalent for applications requiring modular pin configurations.

Q: Do packaging differences affect part selection?

A: The Molex part is supplied in tube packaging while the Samtec part is supplied in bulk packaging. This affects handling, storage, and quantity management but does not impact electrical or mechanical compatibility.

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

A: The Molex part explicitly lists these applications. The Samtec part does not specify applications in the provided data. Verify that the Samtec substitute meets any application-specific requirements for your intended use case.
