Amphenol ICC 68685-306 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68685-306 is a 6-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole board-to-board applications. This connector features gold-plated mating contacts and tin-plated posts, with a push-pull fastening mechanism and UL94 V-0 flammability rating. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts maintain the core electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 68685-306 is determined by strict equivalence in the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (6), mating pitch (0.100"), mounting type (through hole), termination method (solder), and fastening type (push-pull). All substitute parts listed maintain these core specifications.

The 68685-306LF is a direct manufacturer upgrade from Amphenol ICC, differing only in packaging (tube vs. unspecified) and product status (active vs. obsolete), with improved RoHS compliance.

The TE Connectivity parts (146138-4 and 215297-6) are cross-manufacturer equivalents that maintain the same connector topology and mating interface while offering alternative insulation materials and contact finishes within acceptable ranges for this connector category.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring RoHS compliance, the 68685-306LF is the preferred direct substitute, offering identical specifications to the original 68685-306 with active product status and RoHS compliance. This part maintains the same Dubox™ series design and Polyphenylene Sulfide insulation material.

For cross-manufacturer substitution, the TE Connectivity 215297-6 (AMPMODU HV-100 series) provides ROHS3 compliance with the highest inventory availability (5964 units). This part maintains UL94 V-0 flammability rating and equivalent contact geometry, though it uses Polyester glass-filled insulation instead of PPS and includes kinked pin termination as an alternative to standard solder termination.

The TE Connectivity 146138-4 (AMPMODU Mod IV series) is suitable for applications where the specified current rating of 2A is acceptable. This part has lower mating contact finish thickness (10.0µin vs. 30.0µin) and does not specify flammability rating or operating temperature range.

All substitute parts maintain the 0.100" (2.54mm) pitch, 6-position configuration, through-hole mounting, and push-pull fastening mechanism required for mechanical and electrical compatibility with the original 68685-306.

Frequently Asked Questions (FAQ)

Q: Can the 68685-306LF be used as a direct replacement for the 68685-306?

A: Yes. The 68685-306LF is functionally equivalent with identical electrical and mechanical specifications. The primary differences are packaging (tube vs. unspecified) and product status (active vs. obsolete). The 68685-306LF offers improved RoHS compliance.

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

A: The Amphenol ICC 68685-306LF maintains the original Polyphenylene Sulfide insulation material and Dubox™ series design. TE Connectivity parts (146138-4 and 215297-6) use Polyester glass-filled insulation and different series designs (AMPMODU Mod IV and AMPMODU HV-100 respectively). All maintain the same 0.100" pitch, 6-position receptacle configuration and push-pull fastening.

Q: Are there compatibility concerns with different insulation materials?

A: The insulation material change from PPS to Polyester glass-filled in TE Connectivity parts does not affect mating interface compatibility. Both materials meet the same flammability and temperature requirements for this connector category. Mechanical fit and electrical performance remain equivalent.

Q: Which substitute offers the best availability?

A: The TE Connectivity 215297-6 has the highest inventory (5964 units) and includes ROHS3 compliance certification. It is suitable for new designs and production requiring immediate availability.

Q: Does the contact finish thickness difference affect performance?

A: Contact finish thickness variations (10.0µin to 31.5µin) are within acceptable ranges for this connector category. The 146138-4 has lower thickness (10.0µin) compared to the original (30.0µin), while the 215297-6 is nearly equivalent (31.5µin). All finishes provide adequate corrosion protection and electrical conductivity for the specified applications.

Q: Can the 215297-6 kinked pin termination be used interchangeably with solder termination?

A: The 215297-6 supports both kinked pin and solder termination methods. For applications requiring standard solder termination, the kinked pin feature provides additional mechanical retention during assembly. This does not affect electrical compatibility with the original design.
