Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1-745230-1 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts maintain identical specifications in the following categories:

Electrical Parameters: Wire gauge range (18-22 AWG), contact material (phosphor bronze), contact finish (gold), and finish thickness (30.0µin / 0.76µm) are identical across all substitute options.

Mechanical Parameters: Socket contact type, stamped construction method, and crimp termination method are preserved in all substitutes.

Series Compatibility: All substitute parts belong to the AMPLIMITE HDP-20 connector series, ensuring mechanical and electrical compatibility within the same connector family.

Environmental Classification: Moisture sensitivity level 1 (unlimited) is maintained across all parts, indicating no special storage or handling requirements.

The substitute parts differ only in packaging format and product status, with active alternatives available in cut tape packaging and RoHS3 compliance certification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts 1658542-2 and 745230-2 provide complete functional equivalence to the obsolete 1-745230-1 contact. Selection between these two active alternatives is based on availability and compliance requirements rather than electrical or mechanical differences.

1658542-2 is the direct manufacturer substitute with the highest current inventory (63,371 pieces) and RoHS3 compliance certification. This part is recommended for new designs and applications requiring documented RoHS compliance.

745230-2 is an active alternative with substantial inventory availability (12,300 pieces) and RoHS3 compliance certification. This part is suitable for replacement applications and retrofit scenarios where the base product number alignment is preferred.

Both parts are packaged in cut tape format and carry identical electrical and mechanical specifications. The choice between them is determined by supply chain availability, inventory requirements, and internal part numbering preferences within the design or procurement system.

Frequently Asked Questions (FAQ)

Q: Can 1658542-2 and 745230-2 be used interchangeably with 1-745230-1?

A: Yes. Both substitute parts maintain identical electrical and mechanical specifications across all critical parameters including wire gauge, contact material, contact finish, finish thickness, and termination method. They are fully compatible within AMPLIMITE HDP-20 connector assemblies.

Q: What is the difference between the two substitute parts?

A: The substitute parts differ only in base product number designation and current inventory levels. All electrical, mechanical, and environmental specifications are identical. Both are active products with RoHS3 compliance and cut tape packaging.

Q: Why is the original 1-745230-1 marked as obsolete?

A: The original part is classified as obsolete by the manufacturer. Active equivalent alternatives are available with identical specifications and superior compliance certifications (RoHS3).

Q: Are there any packaging differences that affect compatibility?

A: The original part packaging is not specified in available documentation. Both substitute parts are supplied in cut tape (CT) packaging, which is standard for individual contact components and does not affect electrical or mechanical compatibility.

Q: Do the substitute parts require different crimping tools or procedures?

A: No. Both substitute parts use identical crimp termination specifications for 18-22 AWG wire gauges. Existing crimping tools and procedures for the original 1-745230-1 are directly applicable.

Q: What is the significance of RoHS3 compliance on the substitute parts?

A: RoHS3 compliance indicates the substitute parts meet current environmental and hazardous substance restrictions. The original part shows "Not applicable" RoHS status, reflecting its obsolete classification. The substitute parts provide compliance documentation for regulated applications and new design implementations.

Q: Can these contacts be used in applications other than AMPLIMITE HDP-20 connectors?

A: These contacts are designed specifically for the AMPLIMITE HDP-20 connector series. Use outside this series is not supported by the provided specifications.
