Amphenol ICC 68664-008 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68664-008 is a vertical rectangular connector header designed for through-hole mounting applications. This 20-position, 2-row connector with 0.100" (2.54mm) pitch provides board-to-cable/wire connectivity using solder termination and detent lock fastening. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 68664-008 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 20 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Shrouding & Mounting: Shrouded 4-wall design with through-hole mounting
• Termination & Fastening: Solder termination with detent lock
• Contact Geometry: Square contact shape
• Insulation Properties: UL94 V-0 flammability rating and black color

Two substitute parts meet these criteria:

1. 68664-008HLF (Amphenol ICC) - Direct manufacturer variant with identical electrical and mechanical specifications, differing only in RoHS compliance status and packaging format.

2. 103168-8 (TE Connectivity AMP Connectors) - Cross-manufacturer equivalent from the AMPMODU Mod II series meeting all critical dimensional and functional parameters.

Parameter Comparison

Engineering Selection Recommendations

68664-008HLF is the primary substitute for the obsolete 68664-008. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications. The 68664-008HLF is currently in active production status with RoHS compliance, making it the preferred choice for new designs and ongoing production requiring regulatory alignment.

103168-8 from TE Connectivity AMP Connectors serves as a cross-manufacturer equivalent. This part maintains all critical dimensional and functional parameters required for direct substitution. The 103168-8 operates across the temperature range of -65°C to 105°C and carries a 3A current rating. The insulation material differs (thermoplastic versus polyester glass-filled), but both materials meet UL94 V-0 flammability requirements. Contact post finish differs (tin-lead versus unspecified), with the 103168-8 providing 100.0µin (2.54µm) thickness. Minor variations in contact length post (0.125" versus 0.130") and mating length (0.318" versus 0.315") fall within acceptable tolerance ranges for connector interchangeability.

Selection between the two substitutes depends on supply chain availability, compliance requirements, and design specifications. The 68664-008HLF maintains closest alignment with the original part specifications. The 103168-8 provides an alternative source with established production availability and defined operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 68664-008HLF directly replace the obsolete 68664-008?

A: Yes. The 68664-008HLF is a direct Amphenol ICC variant with identical connector type, position count, pitch, shrouding, mounting method, and termination. The primary difference is active production status and RoHS compliance. Electrical and mechanical compatibility is complete.

Q: What are the key differences between the Amphenol ICC 68664-008HLF and the TE Connectivity 103168-8?

A: Both parts meet the critical substitution parameters: 20-position, 2-row header with 0.100" pitch, shrouded 4-wall design, through-hole solder termination, and detent lock fastening. Differences include insulation material (polyester glass-filled versus thermoplastic), contact post finish (unspecified versus tin-lead), and minor contact length variations (0.130" versus 0.125" post length; 0.315" versus 0.318" mating length). Both maintain UL94 V-0 flammability rating and black insulation color.

Q: Are there packaging differences between these substitutes?

A: Yes. The 68664-008 was supplied in standard packaging (unspecified). The 68664-008HLF is supplied in bulk packaging. The 103168-8 is supplied in tray packaging. Packaging format does not affect connector functionality but may impact handling, storage, and procurement workflows.

Q: What is the operating temperature range for these connectors?

A: The 68664-008 and 68664-008HLF do not specify an operating temperature range in their technical data. The 103168-8 operates across -65°C to 105°C. For applications requiring defined temperature specifications, the 103168-8 provides explicit operating parameters.

Q: Are all three parts RoHS compliant?

A: No. The 68664-008 is RoHS non-compliant. The 68664-008HLF is RoHS compliant. The 103168-8 has RoHS status listed as not applicable. For designs requiring RoHS compliance, the 68664-008HLF is the appropriate selection.

Q: What is the current rating for these connectors?

A: The 68664-008 and 68664-008HLF do not specify a current rating. The 103168-8 carries a 3A current rating per contact. For applications with defined current requirements, the 103168-8 provides explicit electrical specifications.

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

A: The 68664-008HLF is a direct replacement for the 68664-008 with no design modifications required. The 103168-8 is mechanically and electrically compatible but features minor dimensional variations in contact lengths. Verification of mating interface compatibility with existing connector housings or cable assemblies is necessary before implementation in production designs.
