Amphenol ICC 87606-320 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87606-320 is a 40-position rectangular receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole board-to-board applications. This connector features gold-plated mating contacts, tin-plated posts, and a push-pull fastening mechanism. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 98424-S52-08ULF is identified as a functionally equivalent alternative based on the following criteria:

Shared Electrical & Mechanical Parameters:

• Board-to-board connector architecture
• Solder termination method
• Gold mating contact finish with tin post finish
• UL94 V-0 flammability rating
• Thermoplastic insulation material
• Square contact geometry
• Copper alloy contact material base

Critical Differences Affecting Substitution: The 98424-S52-08ULF operates at a different pitch (0.079" / 2.00mm) and position count (8 positions) compared to the 87606-320 (0.100" / 2.54mm, 40 positions). This substitute is suitable only for applications where the connector footprint, position count, and pitch requirements can be adapted to the Minitek® 2.00mm series specifications. Direct pin-for-pin replacement is not possible due to these dimensional and positional differences.

Parameter Comparison

Engineering Selection Recommendations

The 98424-S52-08ULF is an active product with RoHS compliance, addressing the obsolescence and regulatory status limitations of the 87606-320. However, substitution requires design-level accommodation due to fundamental differences in connector architecture:

• The 87606-320 is a receptacle (female socket) with 40 positions at 0.100" pitch and through-hole mounting.
• The 98424-S52-08ULF is a header (male pin) with 8 positions at 0.079" pitch and surface-mount technology.

Selection of this substitute is appropriate only when system redesign can accommodate the different pitch, position count, mounting method, and connector gender. Direct mechanical or electrical substitution without PCB layout modification is not feasible.

Frequently Asked Questions (FAQ)

Q: Can the 98424-S52-08ULF directly replace the 87606-320 without PCB modification?

A: No. The substitute differs in pitch (0.079" vs. 0.100"), position count (8 vs. 40), mounting type (surface mount vs. through hole), and connector gender (header vs. receptacle). PCB redesign is required for substitution.

Q: What are the key compatibility criteria for these connectors?

A: Both connectors share solder termination, gold mating contact finish, tin post finish, UL94 V-0 flammability rating, and thermoplastic insulation. These parameters define the substitution relationship. Differences in pitch, position count, and mounting technology are the primary limiting factors.

Q: Why is the 87606-320 listed as obsolete?

A: The product status reflects manufacturer discontinuation. The 98424-S52-08ULF, classified as active, represents a current alternative from the same manufacturer for applications where the connector specifications align with system requirements.

Q: Does the 98424-S52-08ULF offer improved compliance?

A: Yes. The 98424-S52-08ULF is RoHS compliant, whereas the 87606-320 is RoHS non-compliant. This represents a regulatory advantage for new designs or systems subject to RoHS requirements.

Q: What is the significance of the different contact materials?

A: The 87606-320 uses phosphor bronze contacts, while the 98424-S52-08ULF uses copper alloy contacts. Both materials are suitable for solder termination and gold plating. Material selection does not prevent substitution when other parameters align.
