Amphenol ICC 68683-650 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68683-650 is a 100-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in automotive, industrial, and telecommunications environments. This connector features gold-plated mating contacts, through-hole solder termination, and push-pull fastening. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters that must match or exceed the original specification:

Connector Type & Contact Type: Must be Receptacle with Female Socket contacts
Position Count & Pitch: Must be 100 positions at 0.100" (2.54mm) pitch
Row Configuration: Must be 2 rows with 0.100" (2.54mm) row spacing
Mounting & Termination: Must be Through Hole with Solder termination
Fastening Type: Must be Push-Pull
Insulation Color: Must be Black
Flammability Rating: Must meet UL94 V-0
Operating Temperature Range: Must support -55°C minimum (original supports -65°C)
Contact Finish - Mating: Gold or Tin-Lead acceptable based on application requirements

The substitute parts from Mill-Max Manufacturing Corp. (Series 803) and Samtec Inc. (Tiger Claw™ BCS series) meet these core mechanical and electrical compatibility requirements. Variations in contact material, contact finish thickness, insulation material, and post finish do not prevent functional substitution when core parameters align.

Engineering Selection Recommendations

Primary Substitutes (ROHS3 Compliant, Active Status):

The Mill-Max Manufacturing Corp. Series 803 connectors (803-41-100-10-001000, 803-43-100-10-001000, 803-91-100-10-001000, 803-93-100-10-001000) and Samtec Inc. BCS-150-L-D-TE are recommended as primary substitutes. These parts are in active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and production runs.

Secondary Substitute (RoHS Non-Compliant, Active Status):

The Mill-Max 803-99-100-10-001000 and 803-99-100-10-004000 are functionally equivalent but carry RoHS non-compliant status. These are suitable only for applications where RoHS compliance is not required or for legacy system maintenance where the original part specification did not mandate compliance.

Compliance Considerations:

For applications requiring ROHS3 compliance, select from the Mill-Max 803-41, 803-43, 803-91, or 803-93 series, or the Samtec BCS-150-L-D-TE. The original Amphenol ICC 68683-650 is RoHS non-compliant; substitution with compliant alternatives is recommended for new designs.

Temperature Range:

All substitute parts operate at -55°C to 125°C, which is narrower than the original specification of -65°C to 125°C. Applications requiring operation below -55°C must retain the original part or identify alternatives with extended low-temperature ratings.

Frequently Asked Questions (FAQ)

Q: Can Mill-Max 803 series connectors directly replace the Amphenol ICC 68683-650?

A: Yes. All Mill-Max 803 series substitutes maintain identical mechanical and electrical compatibility: 100 positions, 0.100" pitch, 2-row configuration, through-hole solder termination, and push-pull fastening. The primary difference is product status (active vs. obsolete) and compliance certifications.

Q: What is the difference between the various Mill-Max 803 part numbers?

A: The differences lie in contact finish specifications and insulation material. The 803-41 and 803-43 series use Beryllium Copper contacts with different gold finish thicknesses (10.0µin vs. 30.0µin). The 803-91 and 803-93 series also use Beryllium Copper but differ in post finish (Tin vs. Tin-Lead). The 803-99 series uses Tin-Lead mating finish instead of gold. All maintain the same mechanical footprint and electrical performance.

Q: Is the Samtec BCS-150-L-D-TE compatible with the original Amphenol ICC connector?

A: Yes. The Samtec BCS-150-L-D-TE meets all core mechanical and electrical requirements: 100 positions, 0.100" pitch, 2-row configuration, through-hole solder termination, and push-pull fastening. It is ROHS3 compliant and in active production. Minor differences include insulation material (Liquid Crystal Polymer vs. Polyphenylene Sulfide) and voltage rating specification (475VAC vs. 1000V), but these do not prevent functional substitution.

Q: Why is the operating temperature range different in the substitutes?

A: The substitute parts specify -55°C to 125°C, while the original specifies -65°C to 125°C. This represents a narrower low-temperature range. Applications requiring operation below -55°C must evaluate whether this limitation is acceptable or if the original part must be retained.

Q: Which substitute should I select for new designs requiring RoHS compliance?

A: Select from Mill-Max 803-41-100-10-001000, 803-43-100-10-001000, 803-91-100-10-001000, 803-93-100-10-001000, or Samtec BCS-150-L-D-TE. All are ROHS3 compliant and in active production status, ensuring regulatory alignment and long-term supply availability.

Q: Are there packaging differences between substitutes?

A: All substitute parts are supplied in Tube packaging. The original Amphenol ICC 68683-650 packaging is not specified in the provided data. Confirm packaging requirements with your procurement process.

Q: Can I mix different Mill-Max 803 variants in the same assembly?

A: Mechanically and electrically, yes. All 803 series variants maintain identical footprints and electrical performance. However, mixing contact finishes (gold vs. tin-lead) or post finishes (tin vs. tin-lead) may introduce inconsistencies in mating characteristics. Standardize on a single variant per assembly for optimal performance.
