Amphenol ICC 66373-115 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66373-115 is a 34-position rectangular connector housing designed for 0.100" (2.54mm) pitch applications. This shrouded header connector features a two-row configuration with solder/PCB termination and screw mount fastening. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66373-115 is determined by the following critical parameters:

• Connector Configuration: 34-position, 2-row header with 0.100" (2.54mm) pitch and row spacing
• Contact Interface: Male pin configuration for mating compatibility
• Termination Method: Solder/PCB termination capability
• Physical Form Factor: Shrouded housing design

The TE Connectivity AMP Connectors 499726-8 satisfies these core substitution criteria through matching position count, pitch, row configuration, and termination method. Both parts accommodate the same PCB footprint and mating interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The 499726-8 serves as a functional equivalent for the obsolete 66373-115 based on matching electrical and mechanical parameters. The substitute part maintains identical position count, pitch spacing, row configuration, and PCB termination compatibility.

The 499726-8 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, RoHS compliance of the substitute part aligns with current regulatory requirements, whereas the original part carries non-compliant status.

Material composition differs between the two housings (polyester glass-filled versus thermoplastic), and color differentiation exists (blue versus black). These variations do not affect functional substitution for standard PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 499726-8 directly replace the 66373-115 in existing designs?

A: Yes. Both parts share identical position count (34), pitch (0.100"), row configuration (2 rows), and row spacing (0.100"). PCB footprints are compatible, and solder termination methods align.

Q: What are the differences between these two connector housings?

A: The primary differences are insulation material (polyester glass-filled versus thermoplastic), color (blue versus black), and product status (obsolete versus active). These do not affect electrical or mechanical compatibility for standard applications.

Q: Does the RoHS compliance difference impact substitution?

A: The 499726-8 is RoHS compliant while the 66373-115 is not. For applications subject to RoHS regulations, the substitute part provides compliance alignment. For legacy systems without regulatory constraints, both parts function equivalently.

Q: Are contacts included with either connector housing?

A: No. Both the 66373-115 and 499726-8 are supplied as housings only. Contacts must be sourced separately.

Q: What mounting considerations apply to the 499726-8?

A: The 66373-115 specifies screw mount fastening. The 499726-8 mounting type is not specified in available documentation. Verify mounting compatibility with your specific application requirements before implementation.
