TE Connectivity AMP Connectors 745287-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 745287-8 is a pin contact with gold solder cup termination, part of the AMPLIMITE HDP-20 series. This component is classified as obsolete, indicating that the original manufacturer has discontinued production. The part is a stamped brass contact with gold plating (30.0µin thickness) designed for solder cup wire termination applications. Due to its obsolete status, identification of active equivalent parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 745287-8 is determined by strict equivalence across the following critical parameters:

• Series Compatibility: Both parts must belong to the AMPLIMITE HDP-20 series to ensure mechanical and electrical compatibility within the connector assembly.
• Contact Configuration: Pin type with solder cup termination is the defining functional characteristic.
• Material Specification: Brass base material with gold finish at 30.0µin thickness ensures electrical conductivity and corrosion resistance requirements.
• Termination Method: Solder cup termination defines the wire attachment interface and must remain consistent.
• Moisture Sensitivity: MSL 1 rating indicates no moisture sensitivity constraints during storage or handling.

The substitute part 4-745287-7 maintains identical specifications across all these parameters, with the primary distinction being its active product status and updated RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 4-745287-7 is functionally equivalent to 745287-8 across all electrical and mechanical parameters. The primary differentiators are product lifecycle status and regulatory compliance:

Product Status: The main part 745287-8 is obsolete, indicating no future availability from the manufacturer. The substitute 4-745287-7 maintains active production status, ensuring long-term supply chain reliability.

RoHS Compliance: The main part carries RoHS non-compliant status, while the substitute achieves ROHS3 compliance. This distinction is significant for applications subject to European Union Restriction of Hazardous Substances regulations or customer specifications requiring RoHS certification.

Electrical and Mechanical Equivalence: Both parts share identical contact material, finish specification, termination method, and series designation. No functional performance differences exist between the two parts in circuit applications.

For new designs, production runs, and field replacements where regulatory compliance is required, 4-745287-7 is the appropriate selection. For legacy systems with explicit non-compliance requirements or where RoHS exemptions apply, the original part number may be retained if inventory permits.

Frequently Asked Questions (FAQ)

Q: Are 745287-8 and 4-745287-7 electrically interchangeable?

A: Yes. Both parts are pin contacts with identical brass base material, 30.0µin gold plating, and solder cup termination. Electrical performance characteristics are equivalent.

Q: What is the significance of the product status difference?

A: The 745287-8 is classified as obsolete, meaning TE Connectivity has discontinued manufacturing. The 4-745287-7 maintains active production status, ensuring availability for current and future orders. Obsolete parts are subject to supply depletion and price volatility.

Q: Does the RoHS compliance difference affect mechanical compatibility?

A: No. RoHS compliance relates to material composition restrictions and regulatory certification, not mechanical fit or function. Both parts maintain identical dimensions, material composition, and termination interface.

Q: Can 745287-8 be used in applications requiring RoHS certification?

A: No. The 745287-8 is explicitly RoHS non-compliant. Applications subject to RoHS requirements must use 4-745287-7 or equivalent compliant alternatives.

Q: What does the packaging designation "Bulk" mean for 4-745287-7?

A: Bulk packaging indicates the parts are supplied in loose form without individual component packaging. This is standard for contact components and does not affect electrical or mechanical performance.

Q: Are there any wire gauge limitations for these solder cup contacts?

A: Wire gauge information is not specified in the provided parameters for either part. Consult the AMPLIMITE HDP-20 series documentation for wire gauge compatibility and solder cup sizing specifications.

Q: Is the REACH status difference between the parts significant?

A: The main part lists REACH status as affected, while the substitute shows vendor undefined status. For applications in REACH-regulated markets, contact the manufacturer for current REACH compliance documentation for 4-745287-7.
