Amphenol ICC 87409-150 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 87409-150 is a surface mount rectangular connector header designed for board-to-board applications. This component features 100 positions arranged in 2 rows with 0.050" (1.27mm) pitch spacing, utilizing the Rib-Cage™ III series platform. The connector is actively produced and widely deployed in general purpose and military applications requiring reliable signal and power distribution across PCB assemblies.

Identifying equivalent and substitute parts is necessary when addressing supply chain constraints, inventory optimization, or when specific compliance requirements necessitate alternative variants within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 87409-150 is determined by strict equivalence across the following critical parameters:

• Connector type, contact type, and mating interface geometry
• Position count and row configuration (100 positions, 2 rows)
• Pitch specifications (0.050" mating pitch, 0.050" row spacing)
• Mounting technology (surface mount)
• Shrouding configuration (shrouded 4-wall design)
• Termination method (solder)
• Operating temperature range (-55°C to 130°C)
• Current rating (1A DC)
• Flammability and insulation material specifications

The 87409-150LF variant qualifies as a direct substitute based on identical mechanical, electrical, and environmental specifications. The primary distinction between these parts is the contact finish composition on the post termination and RoHS compliance status, which do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 87409-150 and 87409-150LF are active production components within the Rib-Cage™ III connector family and maintain full functional equivalence for board-to-board interconnect applications.

Selection between these variants should be based on regulatory and compliance requirements:

The 87409-150LF is RoHS compliant and REACH affected, making it the appropriate choice for applications subject to European Union environmental directives or customer specifications mandating lead-free termination finishes.

The 87409-150 remains suitable for applications where RoHS compliance is not a requirement and where tin-lead post finishes are acceptable per design specifications.

Both parts share identical mechanical interfaces, electrical ratings, and environmental operating parameters, ensuring direct substitution without design modification or re-qualification when compliance requirements align.

Frequently Asked Questions (FAQ)

Q: Can the 87409-150 and 87409-150LF be used interchangeably in the same PCB assembly?

A: Yes. Both parts are mechanically and electrically equivalent. The primary difference is the post termination finish composition and RoHS compliance status. Interchangeability is determined by your application's compliance requirements and solder process specifications.

Q: What does the "LF" designation in 87409-150LF indicate?

A: The "LF" suffix denotes lead-free termination finish. The 87409-150LF uses tin-based post plating instead of tin-lead, and carries RoHS compliance certification.

Q: Are there any performance differences between tin-lead and tin post finishes?

A: Both finishes meet the specified current rating (1A DC) and operating temperature range (-55°C to 130°C). Post finish selection is driven by regulatory compliance, solder process compatibility, and manufacturing standards rather than performance differentiation.

Q: What inventory considerations apply when selecting between these variants?

A: The 87409-150LF maintains higher stock availability (1273 Pcs) compared to the 87409-150 (962 Pcs). Supply chain planning should account for these inventory levels when determining part selection.

Q: Are both parts suitable for military applications?

A: Yes. Both the 87409-150 and 87409-150LF are specified for general purpose and military applications and maintain identical environmental ratings and flammability certifications.
