Amphenol ICC 77313-102-64LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-102-64LF is an active rectangular connector header designed for through-hole mounting applications. This vertical breakaway header accommodates 64 positions across 2 rows with 0.100" (2.54mm) pitch spacing, suitable for board-to-board or cable interconnection. The connector features solder termination and push-pull fastening, with gold-plated mating contacts and tin-plated posts. Finding equivalent substitute parts becomes necessary when managing inventory constraints, lead time optimization, or sourcing flexibility across multiple suppliers while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-102-64LF is determined by strict equivalence across the following critical parameters:

Connector positioning and pitch: 64 positions, 2 rows, 0.100" (2.54mm) mating pitch, 0.100" (2.54mm) row spacing
Contact configuration: Male pin, square contact shape, solder termination
Mounting and fastening: Through-hole mounting, push-pull fastening, board-to-board or cable style
Electrical performance: 3A current rating per contact
Environmental compliance: UL94 V-0 flammability rating, RoHS compliance status
Contact materials and finishes: Phosphor bronze base material with gold mating surface and tin post finish

The substitute part PBC32DAAN from Sullins Connector Solutions meets all critical substitution criteria. Minor variations in contact finish thickness, insulation material composition, and maximum operating temperature do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

Both the 77313-102-64LF and PBC32DAAN maintain active product status with full RoHS compliance and UL94 V-0 flammability certification. The Amphenol ICC part operates across a maximum temperature range of -65°C to 130°C, while the Sullins equivalent extends to -65°C to 125°C. For applications operating below 125°C, both parts are functionally interchangeable. The minor dimensional variation in contact post length (0.135" versus 0.120") and overall contact length (0.465" versus 0.450") remains within acceptable tolerances for standard through-hole solder joint formation and does not compromise electrical performance or mechanical reliability. Both parts carry identical ECCN and HTSUS classifications, supporting equivalent regulatory and trade compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can PBC32DAAN replace 77313-102-64LF in all applications?

A: Yes, for applications operating within the -65°C to 125°C temperature range. If your design requires operation above 125°C, the 77313-102-64LF is the appropriate selection due to its extended 130°C maximum rating.

Q: Are there physical compatibility concerns with the contact post length difference?

A: No. The 0.015" (0.38mm) difference in contact post length between the two parts does not affect PCB hole engagement or solder joint quality in standard through-hole assembly processes. Both parts maintain equivalent mating contact length and insulation height.

Q: Do both parts support identical current and voltage specifications?

A: Both parts are rated for 3A per contact. Voltage ratings are not specified in the technical data for either part. Consult application-specific requirements and PCB design guidelines for voltage isolation and creepage distance validation.

Q: What is the difference in insulation material between these parts?

A: The 77313-102-64LF uses thermoplastic insulation, while the PBC32DAAN uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability certification and support equivalent operating temperature ranges within their respective specifications.

Q: Are both parts RoHS compliant?

A: Yes. The 77313-102-64LF is RoHS Compliant, and the PBC32DAAN is ROHS3 Compliant. Both meet current RoHS requirements for lead-free solder and restricted substance limitations.

Q: What is the contact finish thickness difference, and does it affect performance?

A: The 77313-102-64LF specifies 30.0µin (0.76µm) mating contact finish thickness, while PBC32DAAN specifies 10.0µin (0.25µm). Both thicknesses provide adequate corrosion resistance and electrical conductivity for standard connector applications. The difference does not impact functional performance in typical operating environments.
