Substitute Part Grouping Explanation

Substitution for the 51732-011 is determined by strict equivalence across the following critical parameters:

• Connector Type & Style: Header with male pins and blades, blade power configuration
• Position Count & Layout: 32 positions with 24 signal and 8 power contacts
• Pitch & Row Configuration: 0.100" (2.54mm) pitch in 4-row arrangement
• Mounting & Termination: Board edge, through-hole, right-angle orientation with solder termination
• Contact Specifications: Gold or Gold GXT™ finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range, MSL 1

The substitute part 51722-10802400ABLF maintains full electrical and mechanical compatibility with the original 51732-011 while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The 51722-10802400ABLF is the direct substitute for the obsolete 51732-011. Both connectors are manufactured by Amphenol ICC within the PwrBlade® series and share identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact layout, mounting configuration, and environmental ratings.

The primary distinction between the two parts is product lifecycle status and regulatory compliance. The 51732-011 is obsolete and RoHS non-compliant, while the 51722-10802400ABLF is an active product with RoHS compliance and REACH compliance documentation. For new designs or ongoing system support requiring current component availability and regulatory alignment, the 51722-10802400ABLF is the appropriate selection.

Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming their equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Are the 51732-011 and 51722-10802400ABLF electrically interchangeable?

A: Yes. Both connectors feature identical 32-position configurations with 24 signal and 8 power contacts, 0.100" pitch, gold contact finish at 30.0µin thickness, and UL94 V-0 flammability rating. They operate across the same temperature range (-20°C to 105°C) and carry the same MSL rating.

Q: What is the primary reason to transition from 51732-011 to 51722-10802400ABLF?
