Parameter Comparison

Engineering Selection Recommendations

The 5-87579-4 connector serves as the direct functional equivalent to the obsolete 87579-4 part. Selection of the substitute part is based on the following engineering criteria:

Product Status Consideration: The 87579-4 is classified as obsolete, while the 5-87579-4 maintains active product status. Active status ensures continued availability, manufacturing support, and compliance with current industry standards.

Regulatory Compliance: The 5-87579-4 achieves RoHS compliance, whereas the 87579-4 is RoHS non-compliant. For applications subject to RoHS regulations or requiring future regulatory alignment, the substitute part satisfies compliance requirements.

Electrical and Mechanical Equivalence: All critical electrical parameters (contact type, position count, pitch, current rating, operating temperature) and mechanical parameters (mounting type, shrouding, termination, fastening) are identical between the main part and substitute. This equivalence ensures direct functional replacement without circuit redesign or PCB modification.

Contact Finish Composition: The substitute part features Tin contact finish in place of Tin-Lead. Both finishes maintain the specified contact finish thickness of 100.0µin (2.54µm) and are compatible with standard solder assembly processes. The Tin finish reflects modern manufacturing practices and environmental compliance.

Packaging Consideration: The substitute part is supplied in Tray packaging, whereas the main part packaging is not specified. Tray packaging is standard for production quantities and does not affect connector functionality.

Frequently Asked Questions (FAQ)

Q: Can the 5-87579-4 be used as a direct replacement for the 87579-4 in existing designs?

A: Yes. The 5-87579-4 maintains identical electrical and mechanical specifications across all critical parameters including contact type, position count, pitch spacing, current rating, operating temperature range, mounting configuration, and shrouding. Direct substitution is supported without design modification.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: Both finishes provide equivalent contact performance and maintain the same finish thickness of 100.0µin (2.54µm). Tin finish reflects current manufacturing standards and environmental compliance practices. Both finishes are compatible with standard solder assembly processes.

Q: Why is the 87579-4 listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The 5-87579-4 represents the current active equivalent, ensuring continued availability and manufacturing support for applications requiring this connector type.

Q: Does the RoHS compliance difference affect connector performance?

A: No. RoHS compliance status does not affect electrical or mechanical performance. The 5-87579-4 achieves RoHS compliance through material composition changes that do not alter functional characteristics. RoHS compliance is a regulatory and environmental requirement rather than a performance specification.

Q: Are the dimensional specifications identical between the two parts?

A: Yes. Contact length (mating and post), insulation height, contact shape, and all other dimensional parameters are identical. The connectors are mechanically interchangeable.

Q: What is the significance of the packaging difference?

A: The 5-87579-4 is supplied in Tray packaging, which is standard for production quantities. Packaging does not affect connector functionality or performance. Tray packaging facilitates automated assembly processes and inventory management.

Q: Can both parts be used interchangeably in the same application?

A: Yes. The 5-87579-4 is a functional equivalent to the 87579-4. Both parts support identical electrical performance, mechanical mounting, and operating conditions. Selection between them should be based on product availability, regulatory requirements, and packaging needs.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by equivalence in contact type, position count, row configuration, pitch spacing, current rating, operating temperature range, mounting type, shrouding configuration, termination method, and fastening mechanism. All these parameters are identical between the 87579-4 and 5-87579-4.
