Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 6-532955-6 qualifies as a substitute for the Amphenol ICC 66527-050 based on the following critical parameters:

• Connector Type & Contact Type: Both are receptacle connectors with female socket contacts
• Position Count & Pitch: Both feature 100 positions at 0.100" (2.54mm) mating pitch
• Row Configuration: Both use 2-row layout with 0.100" (2.54mm) row spacing
• Mounting & Termination: Both are through-hole, right-angle, solder-terminated connectors
• Fastening Mechanism: Both use push-pull fastening
• Contact Finish - Mating: Both feature gold mating contact finish
• Insulation Color: Both are black
• Contact Length - Post: Both measure 0.115" (2.92mm)
• Mechanical Compatibility: Insulation heights (0.240" vs 0.238") and contact post finishes (tin for both) are within acceptable tolerance ranges for board-to-board applications

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 66527-050 and TE Connectivity 6-532955-6 are active products suitable for board-to-board rectangular connector applications. Selection between these parts should be based on the following factors:

Amphenol ICC 66527-050 is appropriate when:

• RoHS non-compliance is acceptable for the application
• Brass contact material is specified
• Polyamide insulation material is required
• Higher mating contact finish thickness (30.0µin) is preferred

TE Connectivity 6-532955-6 is appropriate when:

• ROHS3 compliance is required
• Phosphor bronze contact material is acceptable
• Polyphenylene sulfide insulation material is acceptable
• Guide pin ears feature is beneficial for mechanical alignment
• Lower mating contact finish thickness (15.0µin) is acceptable

Both connectors share identical mechanical pitch, row configuration, mounting orientation, and fastening mechanism, ensuring physical and functional interchangeability in board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Are these connectors mechanically interchangeable? A: Yes. Both connectors feature identical 0.100" (2.54mm) mating pitch, 2-row configuration with 0.100" (2.54mm) row spacing, through-hole right-angle mounting, and push-pull fastening. Insulation heights differ by 0.002" (0.05mm), which is within acceptable tolerance for standard PCB applications.

Q: What is the difference in contact material between these parts? A: The Amphenol ICC 66527-050 uses brass contacts, while the TE Connectivity 6-532955-6 uses phosphor bronze contacts. Both materials are suitable for gold-plated mating surfaces and tin-plated post terminations in standard electrical applications.

Q: Does the difference in mating contact finish thickness affect compatibility? A: No. The Amphenol ICC part features 30.0µin (0.76µm) gold plating versus 15.0µin (0.38µm) on the TE Connectivity part. Both thicknesses provide adequate corrosion protection and electrical conductivity for standard board-to-board connector applications.

Q: What is the significance of the RoHS compliance difference? A: The Amphenol ICC 66527-050 is RoHS non-compliant, while the TE Connectivity 6-532955-6 is ROHS3 compliant. Selection depends on regulatory requirements for the end application. ROHS3 compliance is required for products sold in the European Union and certain other markets.

Q: Are the insulation materials interchangeable? A: The Amphenol ICC part uses polyamide (PA) nylon, while the TE Connectivity part uses polyphenylene sulfide (PPS). Both are glass-filled thermoplastics with UL94 V-0 flammability ratings. Material selection should be based on specific environmental and thermal requirements of the application.

Q: What does the guide pin ears feature on the TE Connectivity connector provide? A: Guide pin ears improve mechanical alignment during mating and reduce insertion force variability. This feature is beneficial in high-volume assembly environments but does not affect electrical performance or basic mechanical compatibility.
