TE Connectivity 2-66506-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-66506-5 is a pin contact for the AMPLIMITE HDP-20 connector series, designed for 20-24 AWG wire gauges with gold-plated brass construction and crimp termination. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure functional compatibility within connector assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2-66506-5 is determined by strict equivalence across the following parameters: AMPLIMITE HDP-20 series membership, pin contact configuration, 20-24 AWG wire gauge compatibility, crimp termination method, brass material with gold finish, and stamped construction type. All identified substitute parts satisfy these core electrical and mechanical requirements. Differences in contact finish thickness (flash versus 30.0µin plating) and product status (obsolete versus active) do not affect functional interchangeability within the connector system. RoHS3 compliance status varies among substitutes but does not alter contact performance specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (1658539-2, 66506-3, and 66506-4) are functionally equivalent to the obsolete 2-66506-5 based on identical core specifications. Selection among active alternatives should prioritize parts with current product status and RoHS3 compliance certification. Part 66506-4 offers the highest inventory availability (51,810 pieces) with flash gold finish matching the original specification and ROHS3 compliance with defined REACH status. Part 1658539-2 provides an alternative base product number within the same series with substantial inventory (38,366 pieces) and full RoHS3 compliance. Part 66506-3 features increased contact finish thickness (30.0µin) with active status and RoHS3 compliance, suitable for applications requiring enhanced plating durability. All three parts are packaged in Cut Tape format and share identical electrical and mechanical performance characteristics with the main part.

Frequently Asked Questions (FAQ)

Q: Can 1658539-2, 66506-3, and 66506-4 be used interchangeably with 2-66506-5?

A: Yes. All substitute parts maintain identical wire gauge (20-24 AWG), contact material (brass), contact finish (gold), termination method (crimp), and construction type (stamped) specifications. They are functionally equivalent within AMPLIMITE HDP-20 connector assemblies.

Q: What is the difference between flash gold finish and 30.0µin plating?

A: Flash gold finish provides minimal plating thickness for corrosion protection, while 30.0µin (0.76µm) represents a thicker, more durable gold layer. Both finishes are compatible with the connector system; selection depends on application durability requirements.

Q: Why is the original part 2-66506-5 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured. Active substitutes (1658539-2, 66506-3, 66506-4) provide equivalent functionality and are currently available for procurement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 Compliant certification. The original 2-66506-5 lists RoHS status as "Not applicable" due to its obsolete classification.

Q: Does packaging format affect compatibility?

A: No. The original part packaging is not specified in the provided data. All substitute parts are supplied in Cut Tape (CT) packaging, which is standard for contact components and does not affect electrical or mechanical performance.

Q: Which substitute part should be selected for new designs?

A: Part 66506-4 is recommended for new designs based on active product status, RoHS3 compliance, defined REACH status (REACH Unaffected), and highest inventory availability. Part 1658539-2 serves as an alternative with equivalent specifications.
