Substitute Part Grouping Explanation

Substitution of the obsolete 87579-7 with the active equivalent 5-87579-7 is based on strict electrical and mechanical parameter compatibility. Both parts share identical core specifications across all critical dimensions and functional characteristics: 20-position configuration, 2.54mm pitch spacing, 2-row layout, through-hole right-angle mounting, shrouded 4-wall construction, detent lock fastening, solder termination, 3A current rating, and -65°C to 105°C operating temperature range.

The primary differentiators between these parts are product status (obsolete versus active), packaging format (unspecified versus tray), contact finish composition (Tin-Lead versus Tin), and regulatory compliance status (RoHS non-compliant versus RoHS3 compliant, REACH Affected versus REACH Unaffected). These differences do not affect electrical or mechanical interchangeability in applications where the connector specifications are met.

Substitution is valid when the following parameters are maintained:

• 20-position, 2-row header configuration
• 2.54mm mating pitch and row spacing
• Through-hole, right-angle mounting geometry
• Shrouded 4-wall connector body
• Detent lock fastening mechanism
• Solder termination method
• 3A current capacity requirement
• Operating temperature range within -65°C to 105°C

Engineering Selection Recommendations

The 5-87579-7 serves as the direct active equivalent for the obsolete 87579-7. Selection of the 5-87579-7 is supported by the following engineering considerations:

Product Status: The 87579-7 is classified as obsolete, limiting long-term availability and procurement viability. The 5-87579-7 maintains active product status, ensuring continued supply chain access and manufacturing support.

Regulatory Compliance: The 5-87579-7 achieves ROHS3 compliance and REACH unaffected status, aligning with current regulatory requirements for electronic components in most jurisdictions. The 87579-7 carries RoHS non-compliant and REACH affected designations, presenting potential compliance barriers for new designs or applications subject to environmental regulations.

Electrical and Mechanical Compatibility: Both parts maintain identical specifications across all functional parameters including connector geometry, contact configuration, pitch spacing, mounting type, termination method, and current/temperature ratings. Direct substitution is electrically and mechanically valid.

Contact Finish Consideration: The 5-87579-7 utilizes tin contact finish compared to the tin-lead finish of the 87579-7. Both finishes maintain equivalent contact thickness (100.0µin / 2.54µm) and are suitable for solder termination applications. Tin finish represents the modern standard for lead-free soldering processes.

For new designs, procurement of replacement inventory, or applications requiring regulatory compliance documentation, the 5-87579-7 is the appropriate selection. Existing designs currently utilizing the 87579-7 may transition to the 5-87579-7 without modification to PCB layouts, mating connector specifications, or electrical performance parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5-87579-7 be used as a direct replacement for the 87579-7 in existing designs?

A: Yes. The 5-87579-7 is electrically and mechanically compatible with the 87579-7. All critical parameters including position count, pitch spacing, row configuration, mounting type, and current rating are identical. PCB layouts and mating connector specifications require no modification.

Q: What is the primary reason for substituting the 87579-7 with the 5-87579-7?

A: The 87579-7 is classified as obsolete, limiting availability and long-term procurement viability. The 5-87579-7 is an active product with current manufacturing support and improved regulatory compliance status (ROHS3 compliant, REACH unaffected).

Q: Are there differences in electrical performance between these parts?

A: No. Both parts maintain identical electrical specifications: 3A current rating, -65°C to 105°C operating temperature range, UL94 V-0 flammability rating, and equivalent contact materials and finishes. Electrical performance is functionally equivalent.

Q: What is the difference in contact finish between the 87579-7 and 5-87579-7?

A: The 87579-7 uses tin-lead contact finish, while the 5-87579-7 uses tin contact finish. Both maintain 100.0µin (2.54µm) finish thickness. Tin finish is the current industry standard for lead-free soldering applications and represents an improvement in environmental compliance.

Q: Does the packaging difference affect compatibility?

A: No. The 87579-7 packaging is unspecified while the 5-87579-7 is supplied in tray packaging. Packaging format does not affect connector functionality, electrical performance, or mechanical interchangeability. Tray packaging provides improved handling and storage characteristics for production environments.

Q: Are there any applications where the 87579-7 cannot be substituted with the 5-87579-7?

A: No. The 5-87579-7 is a complete functional equivalent. Applications requiring the 87579-7 specifications are fully supported by the 5-87579-7 without design modifications or performance compromises.

Q: What is the inventory status for these parts?

A: The 87579-7 has 941 pieces in stock (obsolete status). The 5-87579-7 has 1166 pieces in stock (active status). For new procurement, the 5-87579-7 is the recommended selection due to active product status and superior long-term availability.

Q: Are both parts from the same manufacturer?

A: Yes. Both the 87579-7 and 5-87579-7 are manufactured by TE Connectivity AMP Connectors and belong to the AMPMODU Mod II series, ensuring consistent quality standards and design compatibility.
