Amphenol ICC 68683-616 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68683-616 is a 32-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features gold-plated mating contacts and is rated for -65°C to 125°C operation with 1000V voltage rating. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the 68683-616 is determined by the following critical parameters:

32-position configuration with 2-row layout
0.100" (2.54mm) mating pitch and row spacing
Through-hole solder termination
Receptacle connector type with female socket contacts
Gold-plated mating contacts
-65°C to 125°C operating temperature range
1000V voltage rating
UL94 V-0 flammability rating

Substitute parts must maintain these specifications to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.

Engineering Selection Recommendations

The 68683-616LF is the primary substitute for the obsolete 68683-616. Both parts are from the Amphenol ICC Dubox™ series and share identical electrical and mechanical specifications. The 68683-616LF is currently in active production status and is RoHS compliant, making it the preferred choice for new designs and ongoing procurement.

The TE Connectivity 1-535542-6 (AMPMODU Mod IV series) provides an alternative from a different manufacturer. This part maintains the critical 32-position, 0.100" pitch configuration with through-hole solder termination and gold-plated mating contacts. However, material flammability rating and voltage rating specifications are not provided for this part. The 1-535542-6 is suitable where cross-manufacturer compatibility is acceptable and design constraints permit evaluation of the AMPMODU Mod IV series mechanical interface.

Selection between 68683-616LF and 1-535542-6 depends on design requirements for series consistency, supply chain preferences, and any specific performance criteria not covered in the provided specifications.

Frequently Asked Questions (FAQ)

Q: Can the 68683-616LF directly replace the obsolete 68683-616?

A: Yes. The 68683-616LF maintains identical electrical and mechanical specifications including 32-position configuration, 0.100" pitch, through-hole solder termination, and gold-plated mating contacts. Both are Amphenol ICC Dubox™ series connectors. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What are the key compatibility requirements for substitution?

A: Substitute connectors must maintain 32-position capacity, 0.100" (2.54mm) mating pitch, 2-row layout with 0.100" row spacing, through-hole solder termination, and gold-plated mating contacts. Operating temperature range of -65°C to 125°C and 1000V voltage rating are required for equivalent performance.

Q: How does the TE Connectivity 1-535542-6 differ mechanically?

A: The 1-535542-6 is from the AMPMODU Mod IV series rather than Dubox™. While it maintains the same 32-position, 0.100" pitch configuration and through-hole solder termination, it is classified as a bottom or top entry connector versus board-to-board style. Insulation height is 0.265" (6.73mm) compared to 0.276" (7.00mm) for the 68683-616, and contact post length is 0.130" (3.30mm) versus 0.115" (2.92mm).

Q: What packaging options are available?

A: The 68683-616LF and 1-535542-6 are supplied in tube packaging. The original 68683-616 packaging specification is not provided.

Q: Are there RoHS compliance considerations?

A: The 68683-616 is RoHS non-compliant. The 68683-616LF is RoHS compliant. The 1-535542-6 RoHS status is not applicable. For applications requiring RoHS compliance, the 68683-616LF is the appropriate selection.
