Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: wire gauge (24-28 AWG), contact termination method (crimp), contact material composition (brass or phosphor bronze), contact finish (gold), contact finish thickness (30.0µin minimum), connector series compatibility (AMPLIMITE HDP-20), and contact type (stamped pin). Parts are grouped into two categories based on manufacturer and connector series alignment.

Category 1: TE Connectivity AMPLIMITE HDP-20 Series Direct Equivalents Parts 66507-3, 66507-4, and 1658540-4 maintain identical series designation and manufacturer, with all electrical and mechanical parameters matching the main part specification.

Category 2: Cross-Manufacturer D-Sub Contacts Parts 170-001-170L003 (NorComp Inc.) and 86563003065LF (Amphenol ICC/FCI) provide functional equivalence for 24-28 AWG crimp pin contacts with gold finish, though they are designed for D-Sub connector applications rather than AMPLIMITE HDP-20 series assemblies.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (TE Connectivity AMPLIMITE HDP-20 Series)

Parts 66507-3 and 1658540-4 are direct functional equivalents with active product status and ROHS3 compliance. Both maintain the specified 30.0µin (0.76µm) gold contact finish thickness and brass material composition. Part 66507-3 offers the highest inventory availability at 26,533 pieces. Part 1658540-4 provides an alternative with equivalent specifications and 2,300 pieces in stock.

Part 66507-4 is functionally equivalent with active status and RoHS compliance; however, it specifies a flash gold finish thickness rather than the 30.0µin standard, representing a minor deviation in contact finish specification.

Secondary Substitutes (Cross-Manufacturer D-Sub Contacts)

Parts 170-001-170L003 and 86563003065LF provide electrical and mechanical compatibility for 24-28 AWG crimp pin applications with gold finish. These parts are designed for D-Sub connector systems and are not compatible with AMPLIMITE HDP-20 series assemblies. Selection of these parts requires connector system redesign or adapter solutions.

Part 86563003065LF uses phosphor bronze material instead of brass and includes tin termination finish, introducing material composition differences from the original specification.

Frequently Asked Questions (FAQ)

Q: Can 66507-3 be used as a direct replacement for 3-66507-0 in AMPLIMITE HDP-20 assemblies?

A: Yes. Part 66507-3 maintains identical series designation, wire gauge (24-28 AWG), contact termination (crimp), contact material (brass), contact finish (gold), and contact finish thickness (30.0µin). The part is active with ROHS3 compliance.

Q: What is the difference between 66507-3 and 66507-4?

A: Both parts are TE Connectivity AMPLIMITE HDP-20 series contacts with identical wire gauge, termination, and material specifications. The primary difference is contact finish thickness: 66507-3 specifies 30.0µin (0.76µm), while 66507-4 specifies flash thickness. Part 66507-4 offers significantly higher inventory availability (73,596 pieces versus 26,533 pieces).

Q: Are NorComp 170-001-170L003 and Amphenol 86563003065LF suitable for AMPLIMITE HDP-20 connector assemblies?

A: No. These parts are designed for D-Sub connector systems and are not mechanically compatible with AMPLIMITE HDP-20 series housings. They provide functional equivalence only for 24-28 AWG crimp pin applications in D-Sub applications.

Q: What is the significance of the contact finish thickness specification?

A: Contact finish thickness determines durability and electrical performance in mating cycles. The specified 30.0µin (0.76µm) gold finish provides defined wear characteristics and contact resistance performance. Part 66507-4 with flash finish may exhibit different performance characteristics in high-cycle mating applications.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Cut Tape, Tape & Reel, or bulk) does not affect electrical or mechanical performance. Packaging selection is determined by assembly process requirements and inventory management practices.

Q: Is 1658540-4 equivalent to 3-66507-0?

A: Yes. Part 1658540-4 is a direct equivalent with identical electrical and mechanical specifications, active product status, and ROHS3 compliance. It maintains the AMPLIMITE HDP-20 series designation and all specified contact parameters.

Q: What RoHS compliance status should be selected for new designs?

A: ROHS3 compliance is the current standard. Parts 66507-3 and 1658540-4 both carry ROHS3 certification. Part 66507-4 carries RoHS compliance without the "3" designation, indicating compliance with the original RoHS directive.
