TE Connectivity 3-87579-5 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 3-87579-5 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole, right-angle header connector features 6 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing and is designed for board-to-board or cable interconnection applications. The connector utilizes shrouded 4-wall construction with solder termination and detent lock fastening.

The 3-87579-5 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity. Substitute parts with active product status provide access to current manufacturing and inventory availability while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3-87579-5 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Mechanical Compatibility: Connector type, contact type, number of positions, number of rows, pitch spacing, row spacing, mounting configuration, shrouding design, and fastening mechanism must be identical to ensure physical and functional interchangeability.

Electrical Performance: Contact material, contact shape, current rating, and operating temperature range must match to preserve circuit performance and thermal reliability.

Manufacturing & Termination: Termination method and contact material composition must be consistent with the original design.

Regulatory Compliance: Material flammability rating and environmental classifications must be maintained.

The substitute part 8-87579-5 satisfies all these criteria while differing only in packaging format and product status classification, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 8-87579-5 is a direct functional equivalent to the 3-87579-5 for all electrical and mechanical applications. Both parts share identical connector architecture, contact specifications, and performance ratings within the AMPMODU Mod II series.

The primary distinction between these parts is product lifecycle status and regulatory compliance. The 3-87579-5 is classified as obsolete and carries RoHS non-compliant status. The 8-87579-5 maintains active product status with RoHS compliance certification, indicating current manufacturing support and alignment with modern environmental regulations.

Contact finish composition differs between the parts: the 3-87579-5 uses Tin-Lead plating while the 8-87579-5 uses Tin plating. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are compatible with standard solder termination processes. The Tin finish of the substitute part reflects contemporary manufacturing practices and regulatory requirements.

For new designs, production continuity, or component replacement in existing systems, the 8-87579-5 is the appropriate selection. The substitute part provides equivalent performance with the advantage of active product availability and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Are the 3-87579-5 and 8-87579-5 physically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, mounting configurations, and contact spacing. The 6-position, 2-row header with 0.100" (2.54mm) pitch and right-angle through-hole mounting is identical across both parts. They are directly interchangeable in PCB designs and cable assemblies.

Q: What is the difference in contact finish between these parts?

A: The 3-87579-5 uses Tin-Lead plating while the 8-87579-5 uses Tin plating. Both maintain 100.0µin (2.54µm) thickness. Tin finish is the current standard and reflects RoHS compliance requirements. Both finishes are compatible with standard solder termination and provide equivalent electrical performance.

Q: Why is the 3-87579-5 listed as obsolete?

A: The 3-87579-5 has reached end-of-life status in TE Connectivity's product portfolio. The 8-87579-5 represents the current active equivalent within the AMPMODU Mod II series, ensuring ongoing manufacturing support and availability.

Q: Does the packaging difference affect connector performance?

A: No. The packaging format (tray for 8-87579-5 versus unspecified for 3-87579-5) affects only handling, storage, and logistics. The connector itself and its electrical and mechanical specifications remain identical. Packaging selection is determined by procurement and inventory management requirements.

Q: Is the 8-87579-5 suitable for RoHS-regulated applications?

A: Yes. The 8-87579-5 carries RoHS Compliant certification, making it suitable for applications subject to RoHS directives and regulations. The 3-87579-5 is RoHS non-compliant and should not be used in RoHS-regulated environments.

Q: Can I use the 8-87579-5 as a direct replacement in existing assemblies designed for the 3-87579-5?

A: Yes. The 8-87579-5 is a direct functional replacement. All electrical, mechanical, and thermal specifications are identical. The connector will perform identically in existing circuit designs and assembly processes.

Q: What is the current rating for both connectors?

A: Both the 3-87579-5 and 8-87579-5 are rated for 3A per contact. This rating applies across the full operating temperature range of -65°C to 105°C.

Q: Are there any applications where only the 3-87579-5 should be used?

A: No. The 8-87579-5 is functionally equivalent and superior in terms of product status and compliance. For all new designs and replacements, the 8-87579-5 is the appropriate selection.
