Amphenol ICC 66527-550 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-550 is a 100-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in through-hole, right-angle configurations. This connector is part of the Dubox™ series and is actively manufactured. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Amphenol ICC 66527-550 with the TE Connectivity AMP Connectors 6-532955-6 is based on the following matched parameters:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 100
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Style: Board to board

These parameters define the mechanical and electrical interface compatibility between the main part and substitute part.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 66527-550 and TE Connectivity 6-532955-6 are active products with identical mechanical and electrical interface specifications. The primary distinction is regulatory compliance: the TE Connectivity part is ROHS3 compliant, while the Amphenol ICC part is RoHS non-compliant. Selection between these parts should be based on application regulatory requirements and compliance mandates. Both parts are classified as MSL 1 (Unlimited) and share the same ECCN and HTSUS codes.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-532955-6 directly replace the Amphenol ICC 66527-550 in existing designs?

A: Yes, from a mechanical and electrical interface perspective. Both connectors share identical pitch (0.100"), position count (100), row configuration (2 rows), mounting type (through hole, right angle), and fastening mechanism (push-pull). Physical dimensions are equivalent within tolerance (insulation height 0.240" vs. 0.238").

Q: What are the differences in contact materials between these parts?

A: The Amphenol ICC 66527-550 uses brass contacts, while the TE Connectivity 6-532955-6 uses phosphor bronze contacts. Both are terminated with tin finish on the post and gold finish on the mating surface.

Q: Does the difference in gold plating thickness affect compatibility?

A: The mating surface gold finish thickness differs (30.0µin vs. 15.0µin). Both thicknesses are within industry standards for 0.100" pitch connectors and do not affect mechanical or electrical interface compatibility.

Q: What is the significance of the RoHS compliance difference?

A: The TE Connectivity part is ROHS3 compliant, while the Amphenol ICC part is RoHS non-compliant. Applications subject to RoHS regulations must use the TE Connectivity part. Applications without RoHS requirements may use either part.

Q: Are the insulation materials interchangeable?

A: Both materials (polyamide glass-filled and polyphenylene sulfide glass-filled) are suitable for the specified operating temperature range (-65°C to 125°C for the main part). Material selection does not affect connector interface compatibility.

Q: What packaging format is available for both parts?

A: Both parts are supplied in tube packaging.
