• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Insulation Material: Polyamide (PA), Nylon, Glass Filled
• Insulation Color: Black
• Style: Board to Board or Cable
• Shrouding: Unshrouded

Direct Manufacturer Substitute: The part 5-87543-1 from TE Connectivity AMP Connectors is a direct substitute within the same AMPMODU Mod II series, maintaining identical mechanical and electrical specifications with the exception of contact finish composition (Tin versus Tin-Lead) and RoHS compliance status (RoHS Compliant versus RoHS non-compliant).

Similar Manufacturer Substitute: The part 0022284021 from Molex is a similar substitute from the KK254 series. This part maintains compatibility across all critical parameters with the following distinctions: single row configuration (1 row versus 2 rows), square contact shape, and active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (5-87543-1): The TE Connectivity 5-87543-1 is the primary direct substitute for the obsolete 87543-1. Both components share identical mechanical dimensions, row configuration, and contact geometry. The 5-87543-1 maintains Last Time Buy status, indicating limited future availability. This part is RoHS Compliant and REACH Affected, making it suitable for applications requiring regulatory compliance. The contact finish differs from the original (Tin versus Tin-Lead), which does not affect mechanical compatibility but may impact solderability characteristics in specific assembly processes.

For Alternative Substitution (0022284021): The Molex 0022284021 from the KK254 series is an active product offering long-term availability and ROHS3 compliance with REACH Unaffected status. This part differs structurally with a single-row configuration compared to the two-row design of the original part. The contact dimensions are nominally equivalent with minor variations (0.320" versus 0.318" mating length; 0.120" versus 0.125" post length). The Molex part includes breakaway functionality and UL94 V-0 flammability rating. Selection of this alternative requires confirmation that single-row configuration is compatible with the application's mechanical layout and mating interface requirements.

Compliance Considerations: Applications requiring RoHS compliance should utilize either 5-87543-1 or 0022284021. Applications with REACH-sensitive supply chains should prioritize 0022284021 due to REACH Unaffected status. The original 87543-1 with Tin-Lead finish and RoHS non-compliant status is suitable only for legacy systems without regulatory constraints.

Frequently Asked Questions (FAQ)

Q: Can the 5-87543-1 directly replace the 87543-1 in existing designs? A: The 5-87543-1 maintains identical mechanical and electrical specifications with the 87543-1, including row configuration, contact geometry, and pitch. Direct substitution is mechanically and electrically compatible. The primary difference is contact finish composition (Tin versus Tin-Lead) and RoHS compliance status. Assembly process validation may be required if the original design relied on specific solderability characteristics of Tin-Lead finish.

Q: What are the key differences between the TE Connectivity 5-87543-1 and the Molex 0022284021? A: Both parts maintain 2-position, 2.54mm pitch configuration with identical insulation height and overall contact length. The primary structural difference is row configuration: the 5-87543-1 retains the two-row design of the original part, while the 0022284021 uses a single-row configuration. Contact length variations are minimal (0.002" to 0.005" difference). The Molex part includes breakaway functionality and UL94 V-0 flammability rating. Mechanical layout compatibility must be confirmed before substitution.

Q: Is the single-row Molex 0022284021 compatible with applications designed for the two-row 87543-1? A: Electrical compatibility is maintained across all critical parameters. However, mechanical compatibility depends on the mating interface design. Applications designed for two-row connectors require confirmation that single-row configuration aligns with the PCB layout and mating connector specifications. Contact geometry and pitch remain compatible, but physical spacing and mounting hole patterns may differ.

Q: What is the impact of contact finish differences between Tin-Lead and Tin? A: Both finishes provide equivalent electrical performance and mechanical contact reliability. Tin-Lead finish (original 87543-1) offers superior wetting characteristics in traditional lead-based solder processes. Tin finish (5-87543-1 and 0022284021) is compatible with lead-free solder processes and RoHS-compliant assembly. Assembly process parameters may require adjustment when transitioning between these finishes.

Q: Why is the 5-87543-1 designated as Last Time Buy? A: Last Time Buy status indicates that TE Connectivity has announced end-of-life for this product. Existing inventory is available for procurement, but production will cease. This designation necessitates transition planning to alternative components. The Molex 0022284021 with Active status provides long-term availability for new designs.

Q: Are there any applications where the original 87543-1 cannot be substituted? A: Applications requiring RoHS compliance cannot use the original 87543-1. Applications with REACH-sensitive supply chains should avoid the 5-87543-1 due to REACH Affected status. Applications with strict mechanical layout constraints may not accommodate the single-row Molex 0022284021. Design review is required to confirm substitute compatibility with specific application requirements.

Q: What inventory considerations should guide substitute selection? A: The original 87543-1 has 1063 units in stock with obsolete status. The 5-87543-1 has 1928 units available with Last Time Buy status, providing limited procurement window. The Molex 0022284021 has 15668 units in stock with Active status, ensuring long-term availability. For new designs or long-term production, the Molex part provides supply chain stability.
