TE Connectivity AMP Connectors 6-66507-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6-66507-2 is a pin contact for the AMPLIMITE HDP-20 connector series. This component is a stamped brass pin contact with gold plating, designed for crimp termination on 24-28 AWG wire gauges. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing procurement and system maintenance. Substitute parts must maintain functional compatibility across electrical and mechanical parameters while meeting current compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6-66507-2 is determined by strict equivalence across the following critical parameters:

Electrical and Mechanical Compatibility Parameters:

• Contact type: Pin (not socket)
• Contact termination method: Crimp
• Wire gauge range: 24-28 AWG
• Contact material: Brass
• Contact finish: Gold
• Series compatibility: AMPLIMITE HDP-20
• Stamped construction type

The substitute part 1658540-3 maintains equivalence across all functional parameters required for direct replacement. Differences in contact finish thickness specification (1.18µin versus Flash) and RoHS compliance status do not affect electrical or mechanical interchangeability within the AMPLIMITE HDP-20 connector system.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1658540-3 is the direct equivalent for the obsolete 6-66507-2. Selection of 1658540-3 is supported by the following factors:

Product Status: The substitute part maintains active product status with TE Connectivity AMP Connectors, ensuring ongoing availability and supply chain continuity.

Compliance Posture: The substitute part achieves ROHS3 compliance, addressing regulatory requirements that may apply to new system designs or procurement cycles. The original part's RoHS non-compliant status presents constraints for applications subject to RoHS directives.

Functional Equivalence: All electrical and mechanical parameters remain identical between the main part and substitute, including wire gauge range, contact material, termination method, and series compatibility.

Packaging: The substitute part is available in Cut Tape (CT) packaging with significantly higher inventory levels (36,513 pieces), supporting production requirements and reducing lead time risk.

Frequently Asked Questions (FAQ)

Q: Can 1658540-3 be used as a direct replacement for 6-66507-2 in existing assemblies?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all functional parameters: pin contact type, crimp termination, 24-28 AWG wire gauge, brass material, and gold finish. Both parts are compatible with the AMPLIMITE HDP-20 connector series.

Q: What is the difference between the contact finish specifications listed for each part?

A: The main part specifies contact finish thickness as 1.18µin (0.030µm), while the substitute part specifies Flash. Both designations indicate gold plating applied to the brass contact material. This difference does not affect electrical conductivity or mechanical interchangeability within the connector system.

Q: Does the RoHS compliance difference affect substitution suitability?

A: RoHS compliance status reflects regulatory classification and does not alter the electrical or mechanical function of the contact. The substitute part's ROHS3 compliance provides advantage for applications subject to RoHS directives. Selection should be based on applicable regulatory requirements for the end application.

Q: Are there packaging considerations when sourcing the substitute part?

A: The substitute part 1658540-3 is supplied in Cut Tape (CT) packaging, whereas the original part packaging is not specified. Cut Tape packaging is standard for automated assembly processes. Verify packaging compatibility with your assembly equipment and procurement workflow.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage, handling, or assembly processes.

Q: Are both parts subject to the same export control classifications?

A: Yes. Both parts carry ECCN EAR99 classification and HTSUS code 8536.90.4000, indicating identical export control and tariff treatment.
