Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 66527-520 is determined by strict alignment of the following critical parameters:

  • Connector Type & Contact Type: Must be Receptacle with Female Socket contacts
  • Position Count & Pitch: Must maintain 40 positions at 0.100" (2.54mm) mating pitch
  • Row Configuration: Must be 2-row layout with 0.100" (2.54mm) row spacing
  • Mounting & Termination: Must be Through Hole, Right Angle with Solder termination
  • Fastening Mechanism: Must use Push-Pull fastening
  • Mating Contact Finish: Must be Gold-plated
  • Mechanical Compatibility: Insulation height, contact length, and overall form factor must support direct board-level substitution

The TE Connectivity AMP Connectors part number 5-532955-7 meets all critical substitution criteria. Both connectors share identical position counts, pitch specifications, mounting orientation, and fastening type. Both are rated for board-to-board applications with push-pull engagement and solder termination.

Engineering Selection Recommendations

Both the Amphenol ICC 66527-520 and TE Connectivity 5-532955-7 are active production parts suitable for equivalent substitution in board-to-board connector applications. Selection between these parts should be based on the following factors:

Amphenol ICC 66527-520 is appropriate when:

  • RoHS non-compliant designs are acceptable for the application
  • Higher mating contact finish thickness (30.0µin) is required for extended contact life
  • Dubox™ series compatibility is specified in the design

TE Connectivity 5-532955-7 is appropriate when:

  • RoHS compliance is required by design specification or regulatory requirement
  • Phosphor bronze contact material is compatible with the mating connector
  • AMPMODU Mod II series compatibility is acceptable
  • Lower contact finish thickness (15.0µin mating, 50.0µin post) meets application requirements

Both connectors share identical mechanical pitch, row spacing, mounting orientation, and fastening mechanism, ensuring direct board-level compatibility when substituting between manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-532955-7 be used as a direct replacement for the Amphenol ICC 66527-520?

A: Yes, the TE Connectivity 5-532955-7 is mechanically and electrically compatible for direct substitution. Both connectors feature identical 40-position configuration, 0.100" (2.54mm) pitch, 2-row layout, right-angle through-hole mounting, and push-pull fastening. The primary difference is RoHS compliance status and contact material composition.

Q: What is the difference in contact finish thickness between these two parts?

A: The Amphenol ICC 66527-520 provides 30.0µin (0.76µm) gold plating on mating contacts, while the TE Connectivity 5-532955-7 provides 15.0µin (0.38µm). Both thicknesses are within industry standards for 0.100" pitch rectangular connectors. The thicker plating on the Amphenol part may provide extended contact life in high-cycle mating applications.

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

A: Yes. The Amphenol ICC 66527-520 uses brass contacts, while the TE Connectivity 5-532955-7 uses phosphor bronze contacts. Both materials are suitable for gold-plated rectangular connectors. Phosphor bronze typically offers improved spring characteristics and fatigue resistance.

Q: Which part should be selected for RoHS-compliant applications?

A: The TE Connectivity 5-532955-7 is RoHS compliant. The Amphenol ICC 66527-520 is RoHS non-compliant and should not be used in applications requiring RoHS compliance.

Q: Are both connectors suitable for automotive applications?

A: Both connectors are rated for automotive applications. The Amphenol ICC 66527-520 explicitly lists automotive as an application category. Both parts operate across the -65°C to 125°C temperature range suitable for automotive environments.
