Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-66505-0 is determined by strict equivalence across the following parameters: connector series (AMPLIMITE HDP-20), contact type (socket, stamped), termination method (crimp), wire gauge range (24-28 AWG), base material (phosphor bronze), finish specification (gold flash), and moisture sensitivity classification (MSL 1).

The substitute parts are grouped into two categories:

Direct Manufacturer Equivalents: Parts 1658538-1 and 1658538-3 are functionally identical to the main part across all electrical and mechanical parameters. These parts differ only in packaging format (bulk versus cut tape) and product status (active). Both carry ROHS3 compliance certification.

Similar Manufacturer Alternative: Part 66505-4 maintains identical functional specifications and shares the same base product number family (66505 series). This part is available in cut tape packaging and carries RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

For New Production and Redesign Applications:

Parts 1658538-1 and 1658538-3 are the primary substitutes for the obsolete 1-66505-0. Both parts are active products with ROHS3 compliance certification and maintain complete electrical and mechanical equivalence. Selection between these two direct equivalents depends on packaging requirements: 1658538-1 is supplied in bulk packaging, while 1658538-3 is supplied in cut tape format for automated assembly processes.

For Legacy System Support:

Part 66505-4 serves as an alternative substitute within the same base product family. This part is active and RoHS compliant, offering identical functional specifications. The cut tape packaging format supports both manual and automated assembly workflows.

All three substitute parts are currently in active production status with substantial inventory availability, ensuring supply chain continuity for both immediate and long-term component requirements.

Frequently Asked Questions (FAQ)

Q: Can 1658538-1 and 1658538-3 be used interchangeably with 1-66505-0?

A: Yes. Both parts are direct functional equivalents with identical electrical and mechanical specifications across all critical parameters: wire gauge, contact material, finish specification, termination method, and series compatibility. The only differences are packaging format and compliance certifications (both are ROHS3 compliant versus the obsolete part's not applicable status).

Q: What is the difference between 1658538-1 and 1658538-3?

A: Both parts are electrically and mechanically identical. The difference is packaging: 1658538-1 is supplied in bulk packaging, while 1658538-3 is supplied in cut tape format. Cut tape packaging is optimized for automated pick-and-place assembly, while bulk packaging is suitable for manual assembly or reel-fed processes.

Q: How does 66505-4 compare to the direct equivalents?

A: Part 66505-4 maintains identical functional specifications and shares the same base product number family (66505 series). It differs in RoHS certification level (RoHS Compliant versus ROHS3 Compliant) and is supplied in cut tape packaging. It is functionally interchangeable for all applications requiring 24-28 AWG socket contacts in the AMPLIMITE HDP-20 series.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. All substitute parts are designed for the AMPLIMITE HDP-20 connector series and maintain identical contact geometry, material composition, and electrical characteristics. Direct mechanical and electrical interchangeability is confirmed across all specified parameters.

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

A: For new designs, either 1658538-1 or 1658538-3 is recommended based on assembly process requirements. Both are active products with ROHS3 compliance. Select 1658538-1 for bulk packaging applications or 1658538-3 for automated assembly with cut tape feeding. Part 66505-4 is an acceptable alternative if RoHS (non-3) compliance is sufficient for the application.

Q: What is the inventory status of these substitute parts?

A: All substitute parts maintain substantial inventory: 1658538-1 has 4,040 pieces in stock, 1658538-3 has 47,038 pieces in stock, and 66505-4 has 12,170 pieces in stock. All parts are new original stock.
