Engineering Selection Recommendations

Primary Recommendation: 68683-313LF

The 68683-313LF from Amphenol ICC is the direct equivalent of the obsolete 68683-313. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection of this part eliminates design re-qualification requirements and ensures maximum compatibility with existing PCB layouts and mating connectors.

Secondary Recommendations: TE Connectivity AMPMODU Series

The 1-215307-3 (AMPMODU HV-100) and 6-534206-3 (AMPMODU Mod II) from TE Connectivity are active alternatives suitable for applications where cross-manufacturer qualification is acceptable. Both maintain the 26-position, 0.100" pitch configuration and gold-plated mating contacts. The 6-534206-3 offers higher current rating (2A) and extended inventory availability (20,199 units).

Alternative Options: Preci-Dip 416 Series and Mill-Max 803 Series

The Preci-Dip 416 series (416-83-226-41-003101, 416-83-226-41-018101, 416-87-226-41-003101, 416-87-226-41-018101) and Mill-Max 803 series (803-41-026-10-001000, 803-41-026-10-004000) provide functional substitutes with higher current ratings (3A to 4.5A) and alternative contact materials (Beryllium Copper). These options are suitable for applications requiring enhanced electrical performance or where supplier diversification is a design objective.

Selection should prioritize parts with active product status and compliance certifications matching application requirements. Mechanical fit verification is required for parts with differing insulation heights or contact post lengths.

Frequently Asked Questions (FAQ)

Q: Can 68683-313LF be used as a direct replacement for 68683-313?

A: Yes. The 68683-313LF is the direct equivalent with identical electrical and mechanical specifications. The primary difference is RoHS compliance status. This part is recommended for obsolescence mitigation.

Q: What are the key differences between Amphenol ICC and TE Connectivity alternatives?

A: Both manufacturers produce 26-position, 0.100" pitch receptacles with gold-plated contacts and push-pull fastening. Differences include insulation material composition, contact post length (0.115" to 0.125"), and current rating specifications. TE Connectivity parts offer active product status and higher inventory availability.

Q: Are Preci-Dip and Mill-Max parts compatible with the original 68683-313 mating connectors?

A: Preci-Dip and Mill-Max parts maintain the 26-position, 0.100" pitch, and push-pull fastening required for mechanical compatibility. However, these manufacturers use different contact materials (Beryllium Copper vs. Phosphor Bronze) and insulation materials. Electrical compatibility is maintained, but physical fit verification with existing mating connectors is required due to variations in insulation height and contact post length.

Q: What is the significance of contact material differences (Phosphor Bronze vs. Beryllium Copper)?

A: Both materials are suitable for gold-plated mating contacts. Beryllium Copper offers higher spring force and contact pressure, resulting in improved electrical performance and higher current ratings (3A to 4.5A vs. 2A). Selection depends on application current requirements and contact reliability specifications.

Q: Which substitute part offers the best inventory availability?

A: The TE Connectivity 6-534206-3 (AMPMODU Mod II) offers the highest inventory availability with 20,199 units in stock, followed by 1-215307-3 with 5,641 units. The direct equivalent 68683-313LF has 1,306 units available.

Q: Are there temperature rating differences between substitutes?

A: The original 68683-313 and most substitutes operate from -65°C to 125°C. Preci-Dip and Mill-Max parts operate from -55°C to 125°C, providing a narrower low-temperature range. Application requirements should determine if this difference is acceptable.

Q: What packaging options are available for these substitutes?

A: Packaging varies by part number: Amphenol ICC 68683-313LF is supplied in Tube; TE Connectivity parts in Tray or Tube; Preci-Dip parts in Bulk; Mill-Max parts in Bulk. Packaging selection may affect procurement lead times and handling requirements.
