Amphenol ICC 66527-018 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-018 is a 36-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications with through-hole, right-angle mounting. This connector is part of the Dubox™ series and features gold-plated mating contacts with solder termination and push-pull fastening. The product is currently obsolete, making equivalent substitutes from active product lines necessary for ongoing system support and new designs requiring compatible interconnect solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 66527-018 is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (36), mating pitch (0.100"), number of rows (2), row spacing (0.100"), mounting type (through hole, right angle), termination method (solder), fastening type (push-pull), contact finish (gold), contact shape (square), and insulation color (black).

The TE Connectivity AMP Connectors AMPMODU Mod II series provides four substitute part numbers that maintain these core electrical and mechanical specifications: 5-532955-6, 5-534204-3, 532955-6, and 534204-3. All substitutes are functionally compatible with the 66527-018 for board-to-board interconnect applications requiring 36-position, 0.100" pitch receptacle connectors with right-angle through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

All four TE Connectivity AMP Connectors substitutes maintain functional compatibility with the 66527-018 across core electrical and mechanical parameters. Selection between substitutes depends on regulatory and compliance requirements.

For applications requiring RoHS compliance, 5-532955-6 and 5-534204-3 are the appropriate selections, as both carry RoHS Compliant status. The 5-532955-6 features standard solder termination with 15.0µin gold plating on mating contacts, while 5-534204-3 provides kinked pin termination with 30.0µin gold plating thickness.

For applications where RoHS compliance is not required, 532955-6 and 534204-3 remain functionally equivalent alternatives. The 532955-6 offers standard solder termination with 15.0µin gold plating, while 534204-3 provides kinked pin termination with 30.0µin gold plating and tin-lead post finish.

All substitutes feature guide pin ears and are packaged in tubes. Insulation height varies slightly (0.238" versus 0.240"), and contact material differs from the original brass to phosphor bronze, which does not affect electrical or mechanical compatibility for board-to-board interconnect applications.

Frequently Asked Questions (FAQ)

Q: Are the TE Connectivity AMP Connectors AMPMODU Mod II substitutes mechanically compatible with the Amphenol ICC 66527-018?

A: Yes. All four substitute part numbers maintain identical specifications for connector type, number of positions (36), mating pitch (0.100"), number of rows (2), row spacing (0.100"), mounting type (through hole, right angle), fastening type (push-pull), and contact shape (square). Insulation height varies by 0.002" (0.05mm), which does not affect mechanical fit or board-level compatibility.

Q: What is the difference between the four substitute part numbers?

A: The substitutes differ in two primary aspects: RoHS compliance status and termination method. Part numbers 5-532955-6 and 5-534204-3 are RoHS Compliant, while 532955-6 and 534204-3 are RoHS non-compliant. Additionally, 5-532955-6 and 532955-6 feature standard solder termination, while 5-534204-3 and 534204-3 feature kinked pin solder termination. Gold plating thickness on mating contacts also varies: 15.0µin for 5-532955-6 and 532955-6, and 30.0µin for 5-534204-3 and 534204-3.

Q: Can I use a substitute with kinked pin termination (5-534204-3 or 534204-3) in place of the original solder termination design?

A: Kinked pin termination is compatible with standard PCB solder pads designed for 0.115" (2.92mm) contact post length. The kinked pin design provides additional mechanical retention during soldering. Compatibility depends on PCB pad layout and solder process parameters specific to your application.

Q: What is the significance of the contact material change from brass to phosphor bronze?

A: Phosphor bronze provides improved spring characteristics and wear resistance compared to brass. This material change does not affect electrical conductivity or mating force specifications for 36-position, 0.100" pitch board-to-board applications. The substitutes maintain functional equivalence for standard interconnect requirements.

Q: Which substitute should I select for new designs?

A: For new designs, 5-532955-6 or 5-534204-3 are recommended, as both carry Active product status and RoHS Compliant certification. Selection between these two depends on whether kinked pin termination is preferred for your PCB assembly process. Both are available in production quantities and supported by TE Connectivity.

Q: Are there any voltage or current rating differences between the main part and substitutes?

A: Voltage and current ratings are not specified in the provided data for any of the substitute parts. The original 66527-018 specifies 1250V voltage rating. For applications requiring specific voltage or current ratings, consult the detailed datasheets for each substitute part number.

Q: What packaging is available for the substitute parts?

A: All four substitute part numbers are packaged in tubes, consistent with standard connector distribution for board-to-board applications.
