Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 66925-556 is determined by strict equivalence across the following critical parameters:

Connector Configuration: 112-position receptacle with female socket contacts
Pitch and Spacing: 0.100" (2.54mm) mating pitch and row spacing
Mounting Geometry: Through-hole, right-angle orientation
Contact Interface: Gold-plated mating surface with 30.0µin (0.76µm) thickness
Termination Method: Solder termination on post contacts
Fastening Mechanism: Push-pull fastening type
Flammability Compliance: UL94 V-0 material rating

The TE Connectivity AMP Connectors part number 5-535512-2 meets all these critical substitution criteria. This part is from the AMPMODU Mod II series and maintains functional and mechanical compatibility with the original Amphenol ICC 66925-556 connector.

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 5-535512-2 is the direct substitute for the Amphenol ICC 66925-556. Selection of this substitute is based on the following engineering factors:

Product Status: The original Amphenol ICC 66925-556 is classified as obsolete, making the active-production TE Connectivity 5-535512-2 the appropriate replacement for new designs and ongoing system support.

Compliance and Certifications: Both connectors maintain UL94 V-0 flammability compliance and identical RoHS non-compliant status, ensuring regulatory consistency in applications where the original part was specified.

Mechanical and Electrical Equivalence: The substitute part maintains exact equivalence across all critical parameters including connector configuration, pitch, mounting geometry, contact finish specifications, and fastening mechanism.

Availability: The TE Connectivity 5-535512-2 is available in active production with documented inventory, providing supply chain continuity for applications requiring this connector type.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-535512-2 be used as a direct replacement for the Amphenol ICC 66925-556?

A: Yes. The TE Connectivity 5-535512-2 meets all critical substitution parameters including 112-position configuration, 0.100" (2.54mm) pitch, through-hole right-angle mounting, gold-plated mating contacts, and push-pull fastening. Mechanical and electrical compatibility is established.

Q: What are the key differences between these two connectors?

A: The primary differences are product status (obsolete versus active production), insulation material composition (polyamide versus polyester, both glass-filled), contact post material (brass versus phosphor bronze), and contact post finish thickness (100.0µin versus 50.0µin). Insulation height differs by 0.002" (0.05mm), which is within typical manufacturing tolerance ranges.

Q: Are there any compatibility concerns with PCB mounting?

A: No. Both connectors use identical through-hole, right-angle mounting with solder termination. PCB footprints and mounting hole patterns are compatible.

Q: What is the packaging difference?

A: The Amphenol ICC 66925-556 packaging is not specified in available documentation. The TE Connectivity 5-535512-2 is supplied in tube packaging.

Q: Does the substitute part meet the same environmental specifications?

A: The TE Connectivity 5-535512-2 provides documented operating temperature range (-55°C ~ 125°C) and current rating (2A), specifications not provided for the original Amphenol ICC 66925-556. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Are both parts RoHS compliant?

A: No. Both the Amphenol ICC 66925-556 and TE Connectivity 5-535512-2 are RoHS non-compliant, maintaining consistency for applications where the original part was specified.
