Molex 0010897203 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0010897203 is a through-hole rectangular connector header with 20 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is part of the C-Grid 70280 series and is actively manufactured. The connector features male pins with gold-plated mating contacts and tin-plated posts, designed for board-to-board or cable applications with push-pull fastening. Substitute parts are necessary when the primary part is unavailable, when alternative compliance certifications are required, or when specific contact material or finish specifications better suit application requirements.

Engineering Selection Recommendations

Primary Recommendation: 6-146250-0 (TE Connectivity AMP Connectors)

This part is the optimal substitute for the Molex 0010897203. Both components are ROHS3 compliant, feature identical core electrical and mechanical parameters, and maintain active product status. The 6-146250-0 uses LCP insulation material matching the original specification and provides equivalent functional performance.

Secondary Recommendations: 77313-124-20LF, 77313-424-20LF, 77313-822-20LF, 77313-824-20LF (Amphenol ICC BERGSTIK® Series)

All four Amphenol ICC parts are RoHS compliant and actively manufactured. These connectors meet all core substitution criteria and offer extended operating temperature range (-65°C to 130°C versus unspecified for the original). The BERGSTIK® series provides phosphor bronze contact material with tin plating, delivering robust performance characteristics. Selection among these four variants depends on specific contact length and finish requirements for your application.

Alternative Options: 929665-01-10-I, 929665-02-10-I, 929665-08-10-I (3M Series 929)

These 3M connectors are RoHS compliant and actively produced. They feature gold-plated posts and mating contacts with PBT insulation material. These parts are suitable substitutes when gold plating on both contact surfaces is required. Variants differ in post length specifications.

Not Recommended: 2320-6221-TG (3M Series 2300)

This part is RoHS non-compliant and not suitable for applications requiring RoHS3 certification.

Not Recommended: 4-102973-0-10 (TE Connectivity AMPMODU Mod II)

This part has obsolete product status and is not recommended for new designs or long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the Molex 0010897203?

A: All listed substitute parts share identical core parameters: 20 positions, 2 rows, 0.100" (2.54mm) pitch, through-hole mounting, solder termination, and push-pull fastening. They are mechanically and electrically interchangeable. However, verify contact length, insulation material, and compliance certifications match your specific application requirements before substitution.

Q: What is the difference between the Amphenol ICC BERGSTIK® variants (77313-124-20LF, 77313-424-20LF, 77313-822-20LF, 77313-824-20LF)?

A: These four parts differ in contact length specifications and mating contact finish. The 77313-124-20LF and 77313-824-20LF feature shorter mating contact length (0.266"), while 77313-822-20LF has longer mating contact length (0.305"). The 77313-424-20LF uses tin finish on mating contacts, while the others use gold or gold GXT™ finish. Select based on your specific board thickness and contact finish requirements.

Q: Why is the 3M 2320-6221-TG not recommended?

A: The 2320-6221-TG is RoHS non-compliant, making it unsuitable for applications requiring RoHS3 certification. Additionally, it uses tin-lead post plating, which is restricted in many regulatory environments.

Q: What is the significance of the 3M Series 929 connectors having gold-plated posts?

A: The 929665 series features gold plating on both mating contacts and posts, providing enhanced corrosion resistance and superior contact reliability compared to tin-plated posts. This specification is beneficial for high-reliability applications or environments with potential corrosion exposure.

Q: Is the TE Connectivity 4-102973-0-10 suitable for new designs?

A: No. This part carries obsolete product status, indicating it is no longer actively manufactured. Using obsolete components in new designs creates long-term supply chain risk and is not recommended.

Q: How do contact length variations affect connector selection?

A: Contact length determines mating depth and engagement characteristics. Verify that substitute part contact lengths are compatible with your mating connector or socket specifications. Significant variations may result in improper mating or insufficient contact pressure.

Q: Are all substitute parts UL94 V-0 rated?

A: Yes. All substitute parts listed meet UL94 V-0 flammability rating, matching the original Molex 0010897203 specification.
