Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6-66505-0 is determined by the following critical parameters: wire gauge (24-28 AWG), contact type (socket), termination method (crimp), contact finish (gold), and moisture sensitivity rating (MSL 1). Parts meeting these core electrical and mechanical specifications are classified as direct or similar substitutes.

Direct Substitute Category: Parts maintaining identical electrical characteristics, contact material composition, and finish thickness specifications.

Similar Substitute Category: Parts meeting core electrical requirements with variations in base product number, contact material, or finish thickness specifications, while maintaining functional compatibility within the AMPLIMITE HDP-20 series or equivalent connector families.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1658538-2

The 1658538-2 is the recommended direct substitute for the obsolete 6-66505-0. Both parts maintain identical electrical specifications including 24-28 AWG wire gauge, socket contact type, crimp termination, phosphor bronze material, and 30.0µin gold finish thickness. The 1658538-2 is active in production status with ROHS3 compliance and significantly higher inventory availability (42,934 units), ensuring supply chain continuity.

Secondary Substitutes: TE Connectivity 66505-3 and 66505-4

Both 66505-3 and 66505-4 maintain the AMPLIMITE HDP-20 series designation and share identical electrical characteristics with the main part. The 66505-3 provides ROHS3 compliance with standard 30.0µin gold finish thickness. The 66505-4 offers RoHS compliance with flash gold finish thickness, representing a variation in contact finish specification. Both are active production parts with adequate inventory levels.

Alternative Substitute: NorComp 170-002-170L003

The 170-002-170L003 is a D-Sub connector contact from the NorComp 170 series that meets core electrical requirements: 24-28 AWG wire gauge, socket contact type, crimp termination, and gold finish at 30.0µin thickness. This part differs in base connector family (D-Sub versus AMPLIMITE HDP-20) and contact material (brass versus phosphor bronze). The 170-002-170L003 is ROHS3 compliant and REACH unaffected. Selection of this part requires verification of mechanical compatibility with existing connector housings.

Compliance Considerations

The main part 6-66505-0 is RoHS non-compliant and REACH affected. All recommended substitutes (1658538-2, 66505-3, 66505-4) are RoHS compliant, with 1658538-2, 66505-3, and 170-002-170L003 achieving ROHS3 compliance. Selection of any substitute part addresses regulatory compliance requirements for new designs and updated systems.

Frequently Asked Questions (FAQ)

Q: Can the 1658538-2 directly replace the obsolete 6-66505-0 in existing assemblies?

A: Yes. The 1658538-2 maintains identical electrical and mechanical specifications including wire gauge (24-28 AWG), contact type (socket), termination method (crimp), contact material (phosphor bronze), and finish thickness (30.0µin gold). Both parts are rated MSL 1 (unlimited moisture sensitivity). The primary difference is product status (active versus obsolete) and RoHS compliance improvement.

Q: What is the difference between the 66505-3 and 66505-4 substitutes?

A: Both parts are AMPLIMITE HDP-20 series contacts with identical wire gauge, contact type, and termination specifications. The primary difference is contact finish thickness: 66505-3 features 30.0µin (0.76µm) gold finish, while 66505-4 features flash gold finish. The 66505-3 provides specification alignment with the original 6-66505-0 finish thickness.

Q: Is the NorComp 170-002-170L003 mechanically compatible with AMPLIMITE HDP-20 connector housings?

A: The 170-002-170L003 is a D-Sub connector contact from a different connector family. While it meets the core electrical requirements (24-28 AWG, socket type, crimp termination, gold finish), mechanical compatibility with AMPLIMITE HDP-20 housings cannot be confirmed from provided specifications. This part is suitable only for D-Sub connector applications or systems specifically designed for NorComp 170 series contacts.

Q: What packaging options are available for these substitutes?

A: The TE Connectivity substitutes (1658538-2, 66505-3, 66505-4) are supplied in Cut Tape (CT) packaging. The NorComp 170-002-170L003 is supplied in Tape & Reel (TR) packaging. Packaging selection should align with assembly process requirements and volume specifications.

Q: Are all substitute parts RoHS compliant?

A: The 1658538-2, 66505-3, and 170-002-170L003 are ROHS3 compliant. The 66505-4 is RoHS compliant. The original 6-66505-0 is RoHS non-compliant. Selection of any substitute part satisfies RoHS compliance requirements for regulated applications.

Q: What is the inventory availability for each substitute?

A: Inventory levels are as follows: 1658538-2 (42,934 units), 66505-4 (12,170 units), 66505-3 (1,495 units), and 170-002-170L003 (936 units). The 1658538-2 offers the highest availability for high-volume applications.
