Amphenol ICC 93696-321 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 93696-321 is a 42-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This connector features female socket contacts with gold mating finish, through-hole solder termination, and push-pull fastening. The part is currently listed as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The 93696-321LF qualifies as a direct substitute based on the following critical parameters that determine functional equivalence:

• Connector geometry: Identical 42-position receptacle configuration with 0.100" (2.54mm) pitch and 2-row layout
• Electrical interface: Matching female socket contact type with gold mating finish (30.0µin thickness)
• Mechanical interface: Identical through-hole mounting and solder termination
• Physical dimensions: Same insulation height (0.275"), contact material (phosphor bronze), and board guide features
• Environmental ratings: Equivalent UL94 V-0 flammability classification and MSL 1 moisture sensitivity

The primary distinction between these parts is product status and compliance certification. The 93696-321LF is an active product with RoHS compliance and REACH affected status, whereas the 93696-321 is obsolete with RoHS non-compliant and REACH unaffected designations.

Parameter Comparison

Engineering Selection Recommendations

The 93696-321LF is the designated substitute for the obsolete 93696-321. Selection of the 93696-321LF is appropriate for new designs and procurement due to its active product status and RoHS compliance certification. The electrical and mechanical interfaces are identical, ensuring direct compatibility in existing board-to-board applications.

For legacy systems currently using the 93696-321, the 93696-321LF provides functional equivalence without requiring circuit redesign or PCB layout modification. The RoHS compliance of the 93696-321LF aligns with current regulatory requirements for electronic components in most markets.

Frequently Asked Questions (FAQ)

Q: Are the 93696-321 and 93696-321LF mechanically interchangeable?

A: Yes. Both connectors share identical pitch spacing (0.100"), position count (42), row configuration (2 rows), mounting type (through hole), and physical dimensions. PCB footprints are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and compliance certifications. The 93696-321LF is an active product with RoHS compliance, while the 93696-321 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Can I use the 93696-321LF as a replacement in existing designs?

A: Yes. The 93696-321LF is a direct substitute with no design changes required. It maintains the same contact configuration, pitch, termination method, and fastening mechanism.

Q: What packaging is available for the substitute part?

A: The 93696-321LF is supplied in tube packaging. The original 93696-321 packaging specification was not provided.

Q: Are there any compliance considerations when switching to the 93696-321LF?

A: The 93696-321LF is RoHS compliant and REACH affected, which aligns with current environmental regulations. If your application requires RoHS compliance, the 93696-321LF meets this requirement, whereas the original 93696-321 does not.
