Engineering Selection Recommendations

Primary Recommendation: Molex 0702461601

The Molex 0702461601 is the direct successor to the obsolete 0702461621. Both components share identical mechanical and electrical mating characteristics within the C-Grid 70246 series. The 0702461601 is currently in active production status with ROHS3 compliance, ensuring long-term supply chain availability. The only material difference is the contact post finish (tin vs. tin-lead), which does not affect functional compatibility. This part is recommended as the first-choice replacement.

Secondary Recommendations: TE Connectivity AMP-Latch Series

The TE Connectivity 103308-3, 103309-3, 5103308-3, 5103309-3, and 5104338-3 connectors provide functionally equivalent substitution. All maintain the required 16-position, 2-row configuration with 0.100" pitch and push-pull fastening. The AMP-Latch series offers extended operating temperature range (-65°C to 105°C) and 1A per contact current rating. Parts 5103308-3, 5103309-3, and 5104338-3 carry RoHS compliance certifications. The 5104338-3 variant includes kinked pin termination for enhanced mechanical retention.

Alternative Options: 3M 30316-6002HB and Amphenol ICC Quickie™ Series

The 3M 30316-6002HB (303 series) and Amphenol ICC 52601-G16-4LF / 52601-G16-6LF (Quickie™ series) provide equivalent substitution with active product status and RoHS compliance. The 3M part offers extended operating temperature range (-55°C to 105°C) and 1A current rating. Amphenol ICC parts feature phosphor bronze contact material and are available in two post length configurations (0.120" and 0.150").

KYOCERA AVX 008383016000010 Consideration

The KYOCERA AVX 008383016000010 meets all core substitution criteria with active status and ROHS3 compliance. However, this part features nickel post plating and brass contact material, representing a greater material composition deviation from the original design. Selection of this part should be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0702461601 as a direct replacement for the obsolete 0702461621?

A: Yes. The 0702461601 is the active production equivalent within the same C-Grid 70246 series. All mating dimensions, pitch specifications, shrouding configuration, and contact geometry are identical. The contact post finish differs (tin vs. tin-lead), but this does not affect electrical or mechanical compatibility.

Q: What is the difference between the TE Connectivity 103308-3 and 103309-3?

A: Both parts are functionally equivalent 16-position headers in the AMP-Latch series. The primary difference is packaging format: 103308-3 is supplied in bulk packaging, while 103309-3 is supplied in tube packaging. Contact finish thickness on the mating surface also differs (15.0µin vs. 30.0µin), but both meet the gold plating requirement.

Q: Are the TE Connectivity 5103308-3 and 5103309-3 compatible with the original Molex 0702461621?

A: Yes. Both parts maintain the required 16-position, 2-row 0.100" pitch configuration with identical mating contact geometry. The 5103308-3 and 5103309-3 differ from 103308-3 and 103309-3 primarily in RoHS compliance status and packaging (tray vs. bulk/tube). All four parts are mechanically and electrically interchangeable.

Q: What is the significance of the kinked pin termination on the TE Connectivity 5104338-3?

A: The kinked pin design provides enhanced mechanical retention during PCB assembly and solder reflow. This termination style does not affect mating compatibility but offers improved mechanical stability in high-vibration or thermal cycling applications. All other electrical and mechanical parameters remain equivalent to the standard solder termination variants.

Q: How do the Amphenol ICC 52601-G16-4LF and 52601-G16-6LF differ?

A: Both are Quickie™ series 16-position headers with identical mating characteristics. The primary difference is contact post length: 52601-G16-4LF features 0.120" (3.05mm) posts, while 52601-G16-6LF features 0.150" (3.81mm) posts. Selection depends on PCB thickness and assembly requirements. Both are functionally equivalent for mating purposes.

Q: Does RoHS compliance status affect substitution eligibility?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional compatibility criterion. The original Molex 0702461621 is RoHS non-compliant. For new designs or applications subject to RoHS regulations, select from compliant alternatives: Molex 0702461601, KYOCERA AVX 008383016000010, 3M 30316-6002HB, TE Connectivity 5103308-3, 5103309-3, 5104338-3, or Amphenol ICC 52601-G16-4LF / 52601-G16-6LF.

Q: Can I substitute the KYOCERA AVX 008383016000010 for the Molex 0702461621?

A: Yes, with material composition considerations. The KYOCERA AVX part meets all core electrical and mechanical substitution criteria. However, it features brass contact material and nickel post plating versus the original phosphor bronze and tin-lead. These material differences do not affect mating compatibility but may influence long-term reliability in specific corrosive or high-current environments. Evaluate application-specific requirements before selection.

Q: What packaging options are available for these substitute parts?

A: Substitute parts are available in multiple packaging formats: bulk (Molex 0702461601, TE Connectivity 103308-3), tube (TE Connectivity 103309-3, 5103309-3, 5104338-3), and tray (KYOCERA AVX 008383016000010, 3M 30316-6002HB, TE Connectivity 5103308-3, Amphenol ICC 52601-G16-4LF / 52601-G16-6LF). Packaging selection does not affect component functionality and is determined by procurement and assembly process requirements.
