TE Connectivity AMP Connectors 87543-8 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 87543-8 is a rectangular connector header designed for through-hole mounting applications. This connector is a vertical 16-position header with 2.54mm (0.100") pitch spacing, configured in a 2-row layout for board-to-board or cable interconnection. The part operates as an unshrouded, push-pull fastened connector with solder termination.

The 87543-8 carries an obsolete product status, which necessitates identification of equivalent substitute components for ongoing design support and procurement. Active equivalent parts are available to maintain design continuity and ensure component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 87543-8 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5-87543-8 maintains identical specifications for connector architecture, contact configuration, pitch spacing, mounting methodology, and termination approach.

The following parameters establish substitution validity:

• Connector type classification (Header)
• Contact type and gender (Male Pin)
• Position count and row configuration (16 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting interface (Through Hole)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Contact material composition (Phosphor Bronze)
• Insulation material specification (Polyamide, Nylon, Glass Filled)
• Physical shrouding classification (Unshrouded)
• Application scope (Board to Board or Cable)

The substitute part 5-87543-8 differs only in packaging configuration (Bulk) and product status (Active), with a minor contact finish specification change from Tin-Lead to Tin on both mating and post surfaces.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-87543-8 is the direct equivalent for the obsolete 87543-8. Both components share identical mechanical and electrical specifications across all critical parameters including connector architecture, contact configuration, pitch spacing, and termination methodology.

The primary distinction between the two parts is product status and regulatory compliance. The 87543-8 is classified as obsolete and carries RoHS non-compliant status. The 5-87543-8 maintains active product status and achieves RoHS compliance through substitution of the contact finish specification from Tin-Lead to Tin on both mating and post surfaces. This contact finish modification does not alter the electrical or mechanical performance characteristics of the connector.

For new designs and ongoing production applications, the 5-87543-8 is the appropriate selection. For legacy system support where the original Tin-Lead finish is specifically required, the 87543-8 remains available in current inventory. The contact finish change from Tin-Lead to Tin represents a standard industry transition for RoHS compliance and does not introduce compatibility issues with standard mating connectors or PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 5-87543-8 directly replace the 87543-8 in existing designs?

A: Yes. The 5-87543-8 is mechanically and electrically equivalent to the 87543-8. Both components feature identical 16-position, 2-row header configuration with 0.100" (2.54mm) pitch spacing, through-hole solder termination, and push-pull fastening. The contact finish change from Tin-Lead to Tin does not affect connector performance or mating compatibility.

Q: What is the difference between the Tin-Lead finish on the 87543-8 and the Tin finish on the 5-87543-8?

A: The 87543-8 uses Tin-Lead contact plating, while the 5-87543-8 uses Tin contact plating. Both finishes provide equivalent electrical conductivity and contact reliability. The Tin finish on the 5-87543-8 enables RoHS compliance. The finish thickness remains constant at 100.0µin (2.54µm) on both parts.

Q: Why is the 87543-8 marked as obsolete?

A: The 87543-8 carries obsolete status due to its RoHS non-compliant Tin-Lead contact finish. The 5-87543-8 represents the active production equivalent with RoHS-compliant Tin finish. TE Connectivity maintains the 87543-8 in inventory for legacy system support.

Q: Are there packaging differences between the 87543-8 and 5-87543-8?

A: The 87543-8 is supplied in standard packaging, while the 5-87543-8 is supplied in Bulk packaging. This packaging distinction does not affect component functionality or performance. Selection between packaging options depends on procurement and inventory management requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: Both the 87543-8 and 5-87543-8 carry MSL 1 (Unlimited) classification. This indicates unlimited shelf life without moisture control requirements, making these components suitable for standard storage and handling conditions.

Q: Are these connectors suitable for board-to-board and cable applications?

A: Yes. Both the 87543-8 and 5-87543-8 are classified as Board to Board or Cable style connectors. The unshrouded header design with male pin contacts accommodates both application types.

Q: What is the through-hole post length for PCB mounting?

A: The contact post length is 0.125" (3.18mm) on both the 87543-8 and 5-87543-8. This dimension specifies the length of the pin extending below the insulation body for through-hole PCB insertion and solder termination.
