Amphenol ICC 66527-540 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-540 is an 80-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications in through-hole, right-angle configurations. This connector features gold-plated mating contacts, tin-plated posts, and is rated for operating temperatures from -65°C to 125°C. The part is currently active in production with 865 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 design requirements permit alternative contact materials or compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 66527-540 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 80
• 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 shape: Square
• Contact length - post: 0.115" (2.92mm)

Allowable Variations:

• Contact material: Phosphor bronze is acceptable as an alternative to brass
• Contact finish - mating: Gold plating thickness may vary within industry standards
• Contact finish - post: Gold or tin plating acceptable
• Insulation material: Alternative polymers (PPS) acceptable if mechanical and electrical properties are maintained
• Insulation color: Natural or black acceptable
• Insulation height: Minor variations (±0.002") acceptable
• RoHS compliance status: Both compliant and non-compliant parts listed based on application requirements

The TE Connectivity AMP Connectors 102192-9 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 66527-540 (Primary Part): Use when RoHS non-compliant components are acceptable for the application. This part is active in production with strong inventory availability (865 units). The brass contact material with tin post finish provides established performance in automotive, industrial, and telecommunications applications. Polyamide insulation material is suitable for standard operating temperature ranges.

TE Connectivity 102192-9 (Substitute Part): Use when ROHS3 compliance is required. This part is active in production with adequate inventory (738 units). The phosphor bronze contact material with gold post finish offers alternative contact metallurgy. Polyphenylene sulfide insulation material provides enhanced chemical resistance compared to polyamide. The insulation height is within acceptable tolerance (0.238" vs. 0.240"). Both parts share identical electrical and mechanical mating characteristics, enabling direct substitution in board-to-board applications.

Selection Criteria:

• Regulatory compliance requirements determine primary selection between RoHS non-compliant and ROHS3 compliant options
• Contact material and finish differences do not affect mating compatibility
• Insulation material selection should align with environmental exposure conditions
• Both parts maintain identical pitch, position count, mounting configuration, and fastening mechanism

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 102192-9 directly replace the Amphenol ICC 66527-540 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), position count (80), row configuration (2 rows), mounting type (through hole, right angle), and fastening mechanism (push-pull). The physical and electrical interface is compatible. Differences in contact material (phosphor bronze vs. brass) and post finish (gold vs. tin) do not affect mating compatibility.

Q: What is the significance of the insulation height difference (0.240" vs. 0.238")?

A: The 0.002" difference falls within standard manufacturing tolerances for rectangular connectors in this category. Both dimensions accommodate standard PCB clearances and component spacing requirements. This variation does not impact substitutability.

Q: How does RoHS compliance affect part selection?

A: RoHS compliance is a regulatory requirement determined by end-application and market destination. The Amphenol ICC 66527-540 is RoHS non-compliant, while the TE Connectivity 102192-9 is ROHS3 compliant. Select based on your application's regulatory requirements. Both parts are electrically and mechanically equivalent.

Q: Are there differences in contact material performance between brass and phosphor bronze?

A: Brass and phosphor bronze are both acceptable contact materials for 0.100" pitch rectangular connectors. Phosphor bronze offers enhanced spring properties and wear resistance. Both materials are suitable for the specified operating temperature range (-65°C to 125°C) and voltage rating (1250V). Material selection should align with specific application requirements and contact force specifications.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These connectors do not require special moisture control during storage, handling, or assembly. Standard warehouse conditions are acceptable.

Q: Can these 80-position connectors be used in automotive applications?

A: Yes. Both the Amphenol ICC 66527-540 and TE Connectivity 102192-9 are listed for automotive applications. Verify that the specific RoHS compliance status and contact material meet your automotive supplier requirements and end-use specifications.
