Amphenol ICC 66527-012 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-012 is a 24-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This through-hole, right-angle mounted connector features gold-plated mating contacts and is rated for operating temperatures from -65°C to 125°C. The part is currently active in production with 943 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 66527-012 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 24 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Mounting & Termination: Through-hole, right-angle orientation with solder termination
• Fastening Mechanism: Push-pull fastening type
• Mating Contact Finish: Gold plating on mating surfaces
• Insulation Properties: Black polyamide insulation
• Contact Geometry: Square contact shape

The TE Connectivity AMP Connectors part number 532955-4 meets all critical substitution criteria. Both connectors share identical position counts, pitch specifications, mounting configurations, and fastening mechanisms. Variations in contact finish thickness and base contact material (phosphor bronze vs. brass) remain within acceptable substitution parameters for this connector category, as both materials provide equivalent electrical performance and reliability in the specified operating environment.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 66527-012 and TE Connectivity 532955-4 are active production parts with equivalent regulatory compliance profiles. Both connectors carry RoHS non-compliant status and share identical ECCN and HTSUS classifications, indicating equivalent export and tariff treatment.

The TE Connectivity 532955-4 provides higher inventory availability (1900 units in stock versus 943 units), making it a viable alternative when supply constraints affect the primary part. The connector maintains functional equivalence across all critical electrical and mechanical parameters, including pitch, position count, mounting configuration, and fastening mechanism.

Minor variations in contact finish thickness and base contact material do not affect substitution eligibility within this connector category. Both materials provide adequate electrical conductivity and corrosion resistance for the specified operating environment and voltage rating.

Frequently Asked Questions (FAQ)

Q: What determines whether the TE Connectivity 532955-4 can substitute for the Amphenol ICC 66527-012?

A: Substitution is based on matching critical parameters: 24-position receptacle configuration, 0.100" (2.54mm) pitch spacing, 2-row layout with identical row spacing, through-hole right-angle mounting, solder termination, push-pull fastening, gold mating contact finish, and square contact geometry. Both parts meet these criteria.

Q: Are there differences in contact material between these connectors?

A: Yes. The Amphenol ICC 66527-012 uses brass contacts, while the TE Connectivity 532955-4 uses phosphor bronze contacts. Both materials provide equivalent electrical performance and reliability in this connector application.

Q: Do the connectors have different gold plating thicknesses?

A: The Amphenol ICC 66527-012 specifies 30.0µin (0.76µm) mating contact finish thickness, while the TE Connectivity 532955-4 specifies 15.0µin (0.38µm). Both thicknesses provide adequate corrosion protection and electrical performance for the intended application.

Q: Are both connectors compliant with the same regulatory standards?

A: Both connectors share identical RoHS non-compliant status, ECCN classification (EAR99), and HTSUS code (8536.69.4040). Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. The connectors are mechanically and electrically interchangeable due to matching position counts, pitch specifications, mounting configurations, and contact geometries. PCB layouts and mating connector designs require no modification.

Q: What is the difference in insulation height between the two parts?

A: The Amphenol ICC 66527-012 has an insulation height of 0.240" (6.10mm), while the TE Connectivity 532955-4 measures 0.238" (6.05mm). This 0.002" (0.05mm) difference is negligible for board-to-board spacing calculations.
