Amphenol ICC 68685-409 Rectangular Connector – Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68685-409 is a 9-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in automotive, industrial, telecommunications, and general-purpose environments. This connector features through-hole solder termination, tin contact finish, and operates across -65°C to 125°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution for the 68685-409 is determined by the following critical parameters: 9-position configuration, 0.100" (2.54mm) mating pitch, receptacle connector type with female socket contacts, through-hole solder termination, and push-pull fastening. All substitute parts maintain these core electrical and mechanical specifications.

Substitutes are grouped into two categories:

Direct Amphenol ICC Equivalent: The 68685-409LF is the active production equivalent, maintaining identical mechanical and electrical specifications while offering RoHS compliance and improved availability.

Cross-Manufacturer Alternatives: Mill-Max Manufacturing Corp. 801 series connectors provide functional equivalence with variations in contact finish (gold or tin-lead), insulation material (PCT polyester vs. PPS), and contact geometry (circular vs. square). These alternatives accommodate different application requirements while maintaining the core 9-position, 0.100" pitch, through-hole solder configuration.

Engineering Selection Recommendations

For Direct Replacement: The 68685-409LF is the recommended substitute. It maintains identical mechanical and electrical specifications to the obsolete 68685-409 while offering active product status and RoHS compliance. This part is suitable for new designs and production continuity.

For Alternative Applications: Mill-Max 801 series connectors provide functional equivalence with the following considerations:

Gold-plated variants (801-41 and 801-91 series): Offer enhanced contact durability and corrosion resistance compared to tin finish. Operating temperature range is -55°C to 125°C, which is narrower than the original -65°C specification.
Tin-lead variants (801-99 series): Provide cost-effective alternatives with tin-lead contact finish. Multiple configurations support different insulation heights and contact post lengths. ROHS3-compliant options (801-99-009-10-001000 and 801-99-009-20-001000) are available for regulated applications.
Right-angle configuration (801-99-009-20-001000): Accommodates space-constrained PCB layouts while maintaining electrical and mechanical compatibility.

All Mill-Max alternatives use beryllium copper contacts and PCT polyester insulation, differing from the original phosphor bronze and PPS materials. These substitutes are suitable where the narrower operating temperature range and alternative materials are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 68685-409LF be used as a direct drop-in replacement for the 68685-409?

A: Yes. The 68685-409LF maintains identical pin count (9), mating pitch (0.100"), connector type (receptacle), contact type (female socket), mounting method (through-hole solder), and fastening type (push-pull). The primary differences are product status (active vs. obsolete) and RoHS compliance.

Q: What are the key differences between Amphenol ICC and Mill-Max substitutes?

A: Amphenol ICC 68685-409LF uses phosphor bronze contacts with PPS insulation and operates from -65°C to 125°C. Mill-Max 801 series use beryllium copper contacts with PCT polyester insulation and operate from -55°C to 125°C. Contact finish options differ: tin (Amphenol), gold (801-41/801-91), or tin-lead (801-99).

Q: Which Mill-Max part should I select for RoHS-compliant applications?

A: For RoHS compliance, select 801-99-009-10-001000, 801-99-009-20-001000 (ROHS3 Compliant), or 68685-409LF (RoHS Compliant). These parts meet regulatory requirements for restricted substances.

Q: Does the 801-99-009-20-001000 right-angle configuration affect electrical performance?

A: No. The right-angle mounting is a mechanical variation only. Electrical specifications, pin count, pitch, and contact ratings remain identical to straight-through variants.

Q: Are there packaging differences between these substitutes?

A: Yes. The 68685-409LF is supplied in tube packaging. Mill-Max 801 series are supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the impact of the narrower operating temperature range in Mill-Max parts?

A: Mill-Max 801 series operate from -55°C to 125°C, compared to the original -65°C to 125°C. If your application requires operation below -55°C, the Amphenol ICC 68685-409LF is the appropriate choice.
