Molex 0702461221 Equivalent & Substitute Parts

Part Overview

The Molex 0702461221 is a shrouded rectangular connector header with 12 positions arranged in 2 rows, 0.100" (2.54mm) pitch, designed for through-hole solder termination. This component is classified as obsolete, with 933 units currently in stock. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and long-term supply chain management. Active alternatives from Molex and other manufacturers provide equivalent electrical and mechanical performance with improved availability and compliance certifications.

Substitute Part Grouping Explanation

Substitution of the Molex 0702461221 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: Header with male pins, 12 positions in 2 rows
Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
Mechanical Interface: Shrouded 4-wall design, through-hole mounting, push-pull fastening
Termination Method: Solder termination with square contact shape
Material & Safety Compliance: PBT insulation, UL94 V-0 flammability rating, black color
Environmental Classification: MSL 1 (Unlimited moisture sensitivity)

Substitute parts must maintain these parameters without deviation. Variations in contact finish, contact length, insulation height, or post length do not preclude substitution provided the mating interface and mechanical envelope remain compatible. Parts with different numbers of loaded positions or operating temperature ranges are listed but require application-specific validation.

Engineering Selection Recommendations

Primary Substitute - Molex 0702461201: This is the direct Molex equivalent with identical mechanical and electrical specifications. The 0702461201 is active in production with significantly higher inventory (20,414 units). It achieves ROHS3 compliance, addressing the non-compliant status of the obsolete 0702461221. The insulation material includes glass filling for enhanced mechanical properties. This part is the recommended first choice for direct replacement.

Secondary Substitutes - Samtec TST Series: The Samtec TST-106-02-L-D, TST-106-02-S-D, TST-106-02-S-D-08, and TST-106-02-T-D maintain full mechanical and electrical compatibility with identical pitch, position count, shrouding, and termination. All are ROHS3 compliant and active in production. The TST-106-02-S-D-08 variant has 11 loaded positions instead of 12, requiring application-specific validation. The TST-106-02-T-D uses tin mating finish instead of gold. The TST-106-03-G-D has extended post length (0.565" vs. 0.165") and is suitable only for applications requiring deeper board penetration.

Alternative Substitute - Sullins SBH11-PBPC-D06-ST-BK: This Sullins connector maintains core mechanical compatibility with identical pitch, position count, and shrouding. It is ROHS3 compliant and active. The contact material is brass rather than phosphor bronze, and the post length is shorter (0.118" vs. 0.135"). This part is suitable for applications where contact material substitution is acceptable.

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 classification, and keying slot features. Selection should be based on compliance requirements, inventory availability, and specific application constraints regarding contact finish and material composition.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0702461201 directly replace the obsolete 0702461221?

A: Yes. The 0702461201 is mechanically and electrically identical to the 0702461221. Both share the same C-Grid 70246 series designation, 12-position 2-row configuration, 0.100" pitch, shrouded 4-wall design, and solder termination. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). The 0702461201 is the recommended direct replacement.

Q: Are Samtec TST-106 series connectors compatible with the Molex 0702461221?

A: Yes, with application-specific considerations. The TST-106-02-L-D, TST-106-02-S-D, and TST-106-02-T-D maintain identical mating pitch (0.100"), position count (12 in 2 rows), shrouding (4-wall), and termination method (solder). However, they have longer overall contact length (0.530" vs. 0.500") and different insulation height (0.350" vs. 0.365"). These dimensional differences may affect board clearance and mating depth. Verify mechanical fit in your specific application before substitution.

Q: What is the difference between the Samtec TST-106-02-S-D and TST-106-02-S-D-08?

A: Both parts are mechanically identical with one critical exception: the TST-106-02-S-D-08 has 11 loaded positions instead of 12. This variant is suitable only for applications that do not require all 12 positions to be populated. For full 12-position functionality, use the TST-106-02-S-D.

Q: Does the Sullins SBH11-PBPC-D06-ST-BK work as a substitute?

A: The Sullins part maintains mechanical compatibility with identical pitch, position count, and shrouding. However, it uses brass contacts instead of phosphor bronze and has a shorter post length (0.118" vs. 0.135"). These material and dimensional differences may affect electrical performance and board penetration depth. Validate compatibility with your specific application requirements before substitution.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts (Molex 0702461201, Samtec TST series, and Sullins SBH11-PBPC-D06-ST-BK) are ROHS3 compliant. The original Molex 0702461221 is RoHS non-compliant. If RoHS compliance is a requirement, any of the substitute parts satisfy this criterion.

Q: What is the difference between gold and tin mating finishes?

A: The Samtec TST-106-02-T-D uses tin mating finish, while most other substitutes use gold. Gold provides superior corrosion resistance and lower contact resistance. Tin is more cost-effective but may oxidize over time in certain environments. Select based on your application's environmental exposure and performance requirements.

Q: Can I use the Samtec TST-106-03-G-D as a substitute?

A: The TST-106-03-G-D is mechanically compatible for mating pitch and position count but has significantly extended post length (0.565" vs. 0.135"). This variant is designed for applications requiring deeper board penetration or stacking configurations. It is not a direct substitute for standard through-hole applications. Use only if your application specifically requires extended post length.
