Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across mechanical and electrical parameters. The primary substitute for TE Connectivity 1-87579-7 is the part number 6-87579-7, which maintains identical specifications across all critical dimensions and electrical characteristics.

The substitution logic is based on the following key parameters:

• Connector Position and Row Configuration: Both parts maintain 40 positions in 2 rows with 0.100" (2.54mm) pitch and row spacing
• Mechanical Mounting: Both employ through-hole, right-angle mounting with identical contact lengths and insulation height
• Electrical Performance: Both deliver 3A current rating across the operating temperature range of -65°C to 105°C
• Contact Geometry and Material: Both utilize square-shaped phosphor bronze contacts with identical mating and post lengths
• Shrouding and Fastening: Both feature 4-wall shrouding with detent lock fastening
• Termination Method: Both use solder termination for PCB integration
• Insulation and Flammability: Both employ thermoplastic insulation with UL94 V-0 flammability rating

The primary distinction between these parts lies in product status and contact finish specification, not in form, fit, or function.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-87579-7 serves as the direct active equivalent to the obsolete 1-87579-7 connector header. Selection of the substitute part is based on the following engineering criteria:

Product Status: The 1-87579-7 is classified as obsolete, whereas the 6-87579-7 maintains active product status. This distinction ensures continued availability, technical support, and supply chain reliability for new designs and ongoing production requirements.

Regulatory Compliance: The 6-87579-7 is RoHS compliant, meeting current environmental and regulatory standards for electronic component manufacturing. The 1-87579-7 is RoHS non-compliant, reflecting its obsolete classification and earlier manufacturing standards.

Contact Finish Specification: The substitute part 6-87579-7 utilizes tin contact finish, whereas the main part 1-87579-7 specifies tin-lead finish. Both finishes maintain identical thickness specifications of 100.0µin (2.54µm) and deliver equivalent electrical performance and reliability across the specified operating temperature range of -65°C to 105°C.

Mechanical and Electrical Equivalence: All mechanical dimensions, electrical ratings, and functional characteristics remain identical between the two parts. The 40-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole right-angle mounting, 3A current rating, and UL94 V-0 flammability rating are preserved in the substitute part.

Packaging Consideration: The substitute part is supplied in tray packaging, which is standard for active production components and facilitates automated assembly processes.

For applications requiring the connector header specifications defined by the 1-87579-7, the 6-87579-7 provides full functional and mechanical compatibility with the added benefits of active product status and RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the 6-87579-7 be used as a direct replacement for the 1-87579-7 in existing designs?

A: Yes. The 6-87579-7 is mechanically and electrically equivalent to the 1-87579-7. All critical parameters including position count, pitch, mounting type, contact geometry, current rating, and operating temperature range are identical. The parts are interchangeable at the PCB level.

Q: What is the significance of the contact finish difference between tin-lead and tin?

A: Both contact finishes maintain identical thickness specifications of 100.0µin (2.54µm) and deliver equivalent electrical performance and contact reliability. The tin finish on the 6-87579-7 reflects current manufacturing standards and RoHS compliance requirements. The tin-lead finish on the 1-87579-7 represents earlier manufacturing practices. Both finishes are suitable for solder termination and long-term reliability across the -65°C to 105°C operating temperature range.

Q: Why is the 1-87579-7 listed as obsolete?

A: The obsolete status reflects the part's removal from active production. The 6-87579-7 has replaced it in the manufacturer's current product line, offering the same functionality with updated compliance certifications and manufacturing standards.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and manufacturing standard, not a functional specification. Both parts deliver identical electrical and mechanical performance. The 6-87579-7's RoHS compliance status makes it the preferred choice for new designs and applications subject to environmental regulations.

Q: Are there any restrictions on mixing the 1-87579-7 and 6-87579-7 in the same assembly?

A: No restrictions exist. Both parts are mechanically and electrically identical and can be used interchangeably within the same assembly or design. However, for consistency and supply chain management, using a single part number is recommended.

Q: What is the difference in packaging between the two parts?

A: The 1-87579-7 packaging is not specified in the available documentation. The 6-87579-7 is supplied in tray packaging, which is standard for active production components and optimized for automated assembly processes. Tray packaging does not affect the connector's form, fit, or function.

Q: Can the 40-position 2-row configuration be used in applications requiring different position counts?

A: No. The 40-position, 2-row configuration is fixed for both the 1-87579-7 and 6-87579-7. Applications requiring different position counts require alternative connector models from the AMPMODU Mod II series or other connector families.

Q: What is the current rating limitation for these connectors?

A: Both the 1-87579-7 and 6-87579-7 are rated for 3A per contact. Total current capacity depends on the number of loaded positions and circuit design. Applications exceeding 3A per contact require alternative connector designs with higher current ratings.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both connectors are rated for continuous operation across the -65°C to 105°C temperature range. The thermoplastic insulation material and phosphor bronze contacts maintain performance throughout this range. Applications requiring operation beyond 105°C require alternative connector designs with higher temperature-rated materials.
