Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51732-007 is determined by strict equivalence across the following critical parameters:

• Connector Series & Manufacturer: PwrBlade® series from Amphenol ICC (FCI)
• Position Count & Layout: 26 positions with 24 signal and 2 power contact configuration
• Pitch & Row Configuration: 0.100" (2.54mm) pitch in 4-row arrangement
• Mounting & Termination: Board edge, through-hole, right-angle mounting with solder termination
• Contact Specifications: Male pins and blades with gold or gold GXT™ finish
• Environmental Ratings: UL94 V-0 flammability rating and -20°C ~ 105°C operating temperature range

The 51732-007LF meets all these criteria and qualifies as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 51732-007LF is the direct functional equivalent for the obsolete 51732-007. Both parts share identical electrical and mechanical specifications, including connector geometry, contact configuration, pitch, mounting method, and environmental ratings.

The primary distinction is product status and regulatory compliance. The 51732-007LF is an active product with RoHS compliance and REACH compliance status, whereas the 51732-007 is obsolete and RoHS non-compliant. For new designs or systems requiring regulatory compliance with current component availability, the 51732-007LF is the appropriate selection. Both parts are manufactured by Amphenol ICC (FCI) within the PwrBlade® series and maintain full electrical and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Are the 51732-007 and 51732-007LF mechanically interchangeable?
