Amphenol ICC 76745-1CL-24 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76745-1CL-24 is a 24-position header spacer connector with 0.100" (2.54mm) pitch, designed for through-hole mounting applications. This connector features gold-plated GXT™ mating contacts and is part of the BERGSTIK®, MezzSelect™, and Basics+ series. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 76745-1CL-24 is constrained by the following critical parameters:

• Pitch and Position Spacing: 0.100" (2.54mm) standard spacing
• Mounting Configuration: Through-hole solder termination
• Connector Category: Rectangular connectors within Amphenol ICC product family
• Contact Interface: Gold-plated mating surfaces for reliable electrical connection

The substitute part 87606-405LF shares the same pitch (0.100" / 2.54mm) and through-hole mounting methodology. However, this part operates as a receptacle connector with 10 positions across 2 rows, differing from the 24-position header configuration of the main part. Substitution is applicable only in applications where the reduced position count and receptacle configuration are compatible with the system design.

Parameter Comparison

Engineering Selection Recommendations

The 87606-405LF substitute part is active and RoHS compliant, addressing regulatory compliance requirements that the obsolete 76745-1CL-24 does not meet. However, direct substitution requires design-level compatibility assessment:

• Position Count Mismatch: The substitute provides 10 positions versus 24 positions in the original part. System designs must accommodate this reduced capacity or employ multiple substitute connectors.
• Connector Type Difference: The main part is a header (male) configuration, while the substitute is a receptacle (female) configuration. Mating interface compatibility must be verified.
• Contact Finish Variation: The substitute uses tin plating (78.7µin) instead of gold GXT™ (30.0µin). This affects contact resistance characteristics and environmental durability profiles.

Selection of the 87606-405LF is appropriate for new designs requiring RoHS compliance and active product support. Legacy system maintenance may require sourcing remaining 76745-1CL-24 inventory or redesign to accommodate the substitute's reduced position count and different connector type.

Frequently Asked Questions (FAQ)

Q: Can the 87606-405LF directly replace the 76745-1CL-24 in existing assemblies?

A: Direct replacement is not possible without design modification. The substitute has 10 positions versus 24 positions, and operates as a receptacle rather than a header. The mating interface type must be compatible with your system's connector design.

Q: What is the significance of the pitch specification in connector substitution?

A: Pitch (0.100" / 2.54mm) defines the center-to-center spacing between contact positions. Both parts share identical pitch and row spacing, enabling compatibility at the footprint level if position count and connector type requirements are met.

Q: How does the contact finish difference affect performance?

A: The main part uses gold plating (GXT™, 30.0µin), while the substitute uses tin (78.7µin). Gold provides superior corrosion resistance and lower contact resistance in low-signal applications. Tin is suitable for general-purpose and industrial applications with adequate environmental protection.

Q: Why is the main part listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The substitute 87606-405LF is active and supported, making it the preferred choice for new designs requiring ongoing availability and manufacturer support.

Q: Does the RoHS compliance difference matter for my application?

A: RoHS compliance is mandatory for products sold in regulated markets (EU, China, and others). The obsolete main part is RoHS non-compliant, while the substitute is RoHS compliant. New designs should prioritize the compliant substitute to meet regulatory requirements.

Q: Can multiple 87606-405LF connectors be used to achieve 24-position capacity?

A: Yes, multiple 10-position receptacles can be combined to achieve higher position counts. However, this requires PCB layout redesign and mechanical integration planning to accommodate multiple connector footprints.
