Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

5-146254-5 and 5-146258-5 are direct functional equivalents to the Molex 0702800593. Both are TE Connectivity AMPMODU Mod II series components with LCP insulation material, ROHS3 compliance, and active production status. The 5-146254-5 features tin-plated contacts identical to the main part, while 5-146258-5 offers gold-plated contacts for enhanced corrosion resistance. Both support the full operating temperature range of -65°C to 105°C and 3A current rating.

5-146257-5 and 5-146261-5 provide alternative contact finishes (gold plating) within the same AMPMODU Mod II series and LCP insulation specification. These parts maintain ROHS3 compliance and active production status with significantly higher inventory availability (210258 and 9968 units respectively).

Secondary Substitutes (Active Status, Compliance Variations):

2310-6121-TG (3M 2300 series) is functionally compatible but features gold-plated contacts, thermoplastic glass-filled insulation, and RoHS non-compliance. This part operates at -55°C to 105°C, which is narrower than the main part's unspecified range. Use only when RoHS non-compliance is acceptable for the application.

67996-110HLF and 67996-210HLF (Amphenol ICC BERGSTIK® II series) are compatible alternatives with extended operating temperature range (-65°C to 125°C) and RoHS compliance. These parts feature phosphor bronze contacts with gold plating and support 3A per contact. The primary difference is contact finish thickness (30.0µin for 67996-110HLF; 15.0µin for 67996-210HLF).

Obsolete Parts (Not Recommended for New Designs):

4-103186-0-05, 4-103328-0-05, and 4-103783-0-05 are obsolete TE Connectivity AMPMODU Mod II variants. While functionally compatible, these parts are no longer in active production and should not be selected for new designs. Existing inventory may be available for legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0702800593 with any of the listed parts?

A: Yes, all listed parts meet the critical electrical and mechanical parameters: 10-position, 2-row configuration at 0.100" (2.54mm) pitch with male pins, through-hole solder termination, and push-pull fastening. Differences in contact finish, insulation material, and compliance certifications determine suitability for specific applications.

Q: What is the difference between tin-plated and gold-plated contacts?

A: Tin-plated contacts (0702800593, 5-146254-5, 5-146258-5) provide cost-effective performance for general-purpose applications. Gold-plated contacts (5-146257-5, 5-146261-5, 2310-6121-TG, 67996-110HLF, 67996-210HLF) offer enhanced corrosion resistance and are preferred for high-reliability or harsh-environment applications. Contact finish thickness varies across parts; thicker plating (30.0µin) provides greater durability than thinner finishes (10.0µin to 15.0µin).

Q: Are all substitute parts ROHS3 compliant?

A: No. The Molex 0702800593, 5-146254-5, 5-146258-5, 5-146257-5, and 5-146261-5 are ROHS3 compliant. The 3M 2310-6121-TG and TE Connectivity obsolete parts (4-103186-0-05, 4-103328-0-05, 4-103783-0-05) are RoHS non-compliant. Amphenol ICC parts (67996-110HLF, 67996-210HLF) are RoHS compliant but not specifically ROHS3 certified. Verify compliance requirements for your application before selection.

Q: What is the difference between LCP and thermoplastic insulation materials?

A: Liquid Crystal Polymer (LCP) insulation provides superior dimensional stability, lower moisture absorption, and better high-temperature performance compared to standard thermoplastic. The Molex 0702800593 uses LCP with glass filler. Substitute parts using LCP (5-146254-5, 5-146257-5, 5-146258-5, 5-146261-5) maintain equivalent insulation performance. Parts with thermoplastic insulation (2310-6121-TG, 4-103186-0-05, 4-103328-0-05, 4-103783-0-05) are functionally compatible but may exhibit different moisture sensitivity characteristics.

Q: Can I use obsolete parts in new designs?

A: Obsolete parts (4-103186-0-05, 4-103328-0-05, 4-103783-0-05) should not be used in new designs. These parts are no longer manufactured and inventory is limited. Use active-status alternatives such as 5-146254-5, 5-146258-5, 5-146257-5, or 5-146261-5 for new applications.

Q: What is the operating temperature range for the Molex 0702800593?

A: The Molex 0702800593 datasheet does not specify an operating temperature range. Substitute parts provide reference ranges: TE Connectivity AMPMODU Mod II series operates -65°C to 105°C; 3M 2300 series operates -55°C to 105°C; Amphenol ICC BERGSTIK® II series operates -65°C to 125°C. Consult application requirements and thermal analysis to confirm compatibility.

Q: What is the current rating for the Molex 0702800593?

A: The Molex 0702800593 datasheet does not specify a current rating. Substitute parts with specified ratings support 3A per contact (TE Connectivity and Amphenol ICC parts). For applications requiring current capacity verification, consult the connector manufacturer's detailed specifications.

Q: Are there packaging differences between substitute parts?

A: Yes. The Molex 0702800593 is supplied in bulk packaging. TE Connectivity AMPMODU Mod II parts (5-146254-5, 5-146257-5, 5-146258-5, 5-146261-5) are bulk packaged. Amphenol ICC BERGSTIK® II parts (67996-110HLF, 67996-210HLF) are supplied in bag packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Which substitute part has the highest inventory availability?

A: The TE Connectivity 5-146257-5 has the highest inventory with 210258 units in stock, followed by 5-146261-5 with 9968 units. The Molex 0702800593 has 1030 units available. For applications requiring immediate large-volume procurement, 5-146257-5 provides the best availability.
