Key Parameters

Substitute Part Grouping Explanation

Substitution of the 51732-016 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: 20 total positions with 16 signal and 4 power contacts
• Pitch & Geometry: 0.100" (2.54mm) pitch, 4-row configuration
• Mounting Method: Board edge, through-hole, right-angle orientation
• Contact Specifications: Gold-plated finish at 30.0µin thickness
• Environmental Ratings: UL94 V-0 flammability, -20°C to 105°C operating range
• Termination: Solder attachment

The identified substitute maintains full electrical and mechanical compatibility with these parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 51722-10401600AALF is the direct functional equivalent for the obsolete 51732-016. Both connectors share identical electrical and mechanical specifications across all critical parameters: 20-position blade power header configuration, 0.100" pitch, 4-row layout, board edge through-hole right-angle mounting, and gold-plated contact finish.

The primary distinction is product lifecycle status: the 51732-016 is obsolete while the 51722-10401600AALF maintains active production status. Additionally, the substitute part is RoHS compliant, whereas the original part is RoHS non-compliant. For new designs or systems requiring compliance with current environmental regulations, the 51722-10401600AALF is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, both parts remain electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are the 51732-016 and 51722-10401600AALF fully interchangeable?

A: Yes. Both connectors are identical in electrical and mechanical specifications, including position count, pitch, contact layout, mounting method, contact finish, and operating temperature range. They are direct substitutes for board-level applications.

Q: Why is the 51732-016 listed as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 51722-10401600AALF represents the active production equivalent within the PwrBlade® series.

Q: What is the difference in RoHS compliance between these parts?

A: The 51732-016 is RoHS non-compliant, while the 51722-10401600AALF is RoHS compliant. This distinction is relevant for applications subject to environmental regulations or customer requirements mandating RoHS compliance.

Q: Does packaging differ between these parts?

A: The 51732-016 packaging is not specified in available documentation. The 51722-10401600AALF is supplied in tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Can I use the 51722-10401600AALF as a drop-in replacement in existing designs?

A: Yes. The substitute maintains full compatibility with existing PCB layouts, mating connectors, and electrical requirements. No design modifications are necessary.

Q: Are there any performance differences between these connectors?

A: No. Both parts operate within the same temperature range (-20°C to 105°C), maintain identical contact specifications, and provide equivalent electrical performance for blade power applications.
