Key Parameters

Substitute Part Grouping Explanation

Substitution between the main part 1-745288-7 and the equivalent part 6-745288-4 is determined by the following critical parameters that must remain consistent:

Required Matching Parameters:

• Manufacturer: TE Connectivity AMP Connectors
• Series: AMPLIMITE HDP-20
• Category: Contacts
• Type: Stamped
• Pin or Socket: Socket
• Contact Material: Phosphor Bronze
• Packaging: Bulk
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Allowable Variation:

• Contact Termination: The main part features solder termination, while the substitute part features solder cup termination. Both termination methods are solder-based and compatible within the AMPLIMITE HDP-20 series framework.
• RoHS Status: The main part is RoHS non-compliant, while the substitute part is RoHS compliant. This difference reflects manufacturing process updates and regulatory compliance evolution.

Both parts share the same base product number (745288) and are classified as active products, confirming their interchangeability within the specified connector series.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The part 6-745288-4 is the direct substitute for 1-745288-7 within the AMPLIMITE HDP-20 connector series. Both parts maintain identical core specifications: stamped socket contacts manufactured from phosphor bronze with unlimited moisture sensitivity rating.

Compliance Considerations:

The substitute part 6-745288-4 is RoHS compliant, whereas the main part 1-745288-7 is RoHS non-compliant. Applications subject to RoHS regulatory requirements should specify part number 6-745288-4. Applications without RoHS constraints may utilize either part number.

Termination Method Distinction:

The primary technical difference between these parts is the contact termination method. Part 1-745288-7 features standard solder termination, while part 6-745288-4 features solder cup termination. Both termination styles are compatible with AMPLIMITE HDP-20 series connector assemblies and provide equivalent electrical performance.

Inventory and Availability:

Part 6-745288-4 maintains higher inventory levels (10,586 pieces) compared to part 1-745288-7 (877 pieces), supporting supply chain continuity and extended lead time mitigation.

Frequently Asked Questions (FAQ)

Q: Can part 6-745288-4 be used as a direct replacement for part 1-745288-7?

A: Yes. Both parts are socket contacts within the AMPLIMITE HDP-20 series, manufactured from phosphor bronze with identical stamped construction. The primary difference is the contact termination method (solder cup versus solder) and RoHS compliance status. Both termination methods are compatible within the series.

Q: What is the difference between solder and solder cup termination?

A: Solder termination (1-745288-7) and solder cup termination (6-745288-4) are both solder-based connection methods. The solder cup variant features a recessed cup geometry designed to retain solder during the soldering process. Both methods provide equivalent electrical connectivity within AMPLIMITE HDP-20 assemblies.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance reflects manufacturing process and material composition standards established for environmental and regulatory purposes. Both the RoHS-compliant and non-compliant versions of these socket contacts deliver identical electrical performance and mechanical characteristics.

Q: Are both parts available in the same packaging format?

A: Yes. Both part 1-745288-7 and part 6-745288-4 are supplied in bulk packaging, supporting equivalent handling and integration into manufacturing workflows.

Q: Which part should be selected for new designs?

A: Selection between these parts depends on application requirements. For applications requiring RoHS compliance, specify part 6-745288-4. For applications without RoHS constraints, either part is suitable. Both parts are active products with confirmed availability.

Q: Are these parts interchangeable within existing AMPLIMITE HDP-20 connector assemblies?

A: Yes. Both parts are socket contacts within the AMPLIMITE HDP-20 series with identical contact material, construction type, and moisture sensitivity rating. They are interchangeable within connector assemblies designed for this series.
