Amphenol ICC 66527-010LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66527-010LF is a 20-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole, right-angle board-to-board applications. This connector features gold-plated mating contacts and is part of the Dubox™ series. The product is currently active in production with 818 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 manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 66527-010LF are identified based on strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 20 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 mounting with solder termination
• Fastening Mechanism: Push-pull fastening type
• Mating Contact Finish: Gold plating
• Contact Shape: Square contacts
• Regulatory Compliance: RoHS compliance and MSL rating

The identified substitutes are TE Connectivity AMP Connectors part numbers 5-532955-3 and 5-534204-9, both from the AMPMODU Mod II series. These parts satisfy all critical mechanical and electrical parameters required for direct substitution in board-to-board connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both TE Connectivity substitutes maintain active product status and comply with RoHS requirements, ensuring regulatory alignment with the original Amphenol ICC 66527-010LF.

5-532955-3: This substitute provides equivalent mechanical compatibility with all critical parameters. The contact finish thickness on mating surfaces is reduced to 15.0µin (0.38µm) compared to the original 30.0µin (0.76µm), and the contact material is phosphor bronze rather than brass. The part includes guide pin ears as a design feature. Current inventory is 66,060 units.

5-534204-9: This substitute matches the original contact finish thickness specification at 30.0µin (0.76µm) on mating surfaces and maintains the same gold plating thickness. The termination includes kinked pin configuration in addition to solder termination. Contact material is phosphor bronze. The part includes guide pin ears and carries ROHS3 compliance certification. Current inventory is 1,549 units.

Selection between substitutes depends on specific application requirements regarding contact material composition, finish thickness, and termination configuration. Both parts satisfy the core mechanical and electrical substitution criteria for the 66527-010LF.

Frequently Asked Questions (FAQ)

Q: What makes these parts suitable substitutes for the 66527-010LF?

A: Both substitute parts maintain identical connector type, position count, pitch spacing, row configuration, mounting orientation, and fastening mechanism. All three parts are 20-position receptacles with 0.100" (2.54mm) pitch, through-hole right-angle mounting, and push-pull fastening. This alignment of critical parameters enables direct mechanical and electrical substitution.

Q: Are there differences in contact material between the original and substitutes?

A: Yes. The 66527-010LF uses brass contacts, while both TE Connectivity substitutes use phosphor bronze contacts. Both materials are suitable for gold-plated mating surfaces in rectangular connector applications. The contact material difference does not prevent substitution when electrical and mechanical parameters align.

Q: How do the gold plating thicknesses compare?

A: The 66527-010LF specifies 30.0µin (0.76µm) gold plating on mating contacts. The 5-532955-3 provides 15.0µin (0.38µm), while the 5-534204-9 matches the original at 30.0µin (0.76µm). Both thicknesses are within industry standards for rectangular connectors. Selection depends on application-specific wear and durability requirements.

Q: What is the significance of the kinked pin termination on the 5-534204-9?

A: The kinked pin termination on the 5-534204-9 provides enhanced mechanical retention during PCB assembly and solder reflow processes. This feature does not affect electrical performance or mechanical compatibility with mating connectors. Both straight solder and kinked pin terminations are acceptable for board-to-board applications.

Q: Do all three parts have the same insulation height?

A: The 66527-010LF specifies 0.240" (6.10mm) insulation height, while both TE Connectivity substitutes specify 0.238" (6.05mm). This 0.002" (0.05mm) difference is within typical manufacturing tolerances and does not affect mechanical fit or electrical performance in standard board-to-board applications.

Q: Are there any compliance differences between the parts?

A: The 66527-010LF and 5-532955-3 are RoHS Compliant. The 5-534204-9 carries ROHS3 Compliant certification, which represents an updated compliance standard. All three parts are EAR99 classified and share the same HTSUS code (8536.69.4040). All parts have MSL rating of 1 (Unlimited).

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

A: Yes, for applications where the original 66527-010LF is specified. The mechanical compatibility across all critical parameters—position count, pitch, row spacing, mounting type, and fastening mechanism—enables direct substitution. PCB footprints and mating connector compatibility remain unchanged.
