Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 745288-4 with active equivalent components is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Series designation (AMPLIMITE HDP-20)
• Contact type (Stamped socket)
• Termination method (Solder)
• Base material (Phosphor Bronze)
• Surface finish specification (Gold at 30.0µin thickness)
• Moisture sensitivity classification (MSL 1)

The substitute part 5-745288-5 maintains identical electrical and mechanical characteristics across all critical parameters. The primary distinction is product status transition from obsolete to active, accompanied by RoHS compliance upgrade and packaging format change from standard to bulk.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-745288-5 is the direct functional equivalent for the obsolete 745288-4. Selection of the substitute component is based on the following engineering criteria:

Product Status: The original part 745288-4 is classified as obsolete, limiting availability for new production and field service applications. The substitute 5-745288-5 maintains active product status with current manufacturing support.

Regulatory Compliance: The substitute part achieves RoHS compliance, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution. The original part is RoHS non-compliant.

Electrical and Mechanical Equivalence: All critical functional parameters remain identical between the original and substitute components, including contact material, finish specification, termination method, and series compatibility.

Packaging Consideration: The substitute is supplied in bulk packaging format, which may require adjustment to procurement and inventory management procedures compared to standard packaging of the original part.

Frequently Asked Questions (FAQ)

Q: Can 5-745288-5 be used as a direct replacement for 745288-4 in existing designs?

A: Yes. The substitute part 5-745288-5 maintains identical electrical and mechanical specifications across all critical parameters including contact material, gold finish thickness, solder termination, and AMPLIMITE HDP-20 series compatibility. The components are functionally equivalent for connector assembly applications.

Q: What is the primary reason for substitution?

A: The original part 745288-4 is classified as obsolete. The substitute 5-745288-5 is an active product with current manufacturing availability and support.

Q: Are there compliance differences between the two parts?

A: Yes. The substitute part 5-745288-5 is RoHS compliant, while the original 745288-4 is RoHS non-compliant. Both parts maintain identical ECCN and HTSUS classifications.

Q: Does packaging format affect component performance?
