Substitute Part Grouping Explanation

Substitution eligibility for the 51772-007 is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle, Female Sockets and Blade Sockets
• Number of Positions: 29
• Pitch: 0.100" (2.54mm)
• Number of Rows: 4
• Mounting Type: Board Edge, Through Hole, Right Angle
• Termination Method: Press-Fit
• Contact Layout: 24 Signal, 5 Power
• Contact Finish: Gold or Gold, GXT™
• Contact Finish Thickness: 30.0µin (0.76µm)
• Color: Black
• Material Flammability Rating: UL94 V-0
• Operating Temperature Range: -20°C ~ 105°C
• Series: PwrBlade®

Parts meeting all these criteria are classified as direct equivalents and may be substituted without modification to the connector interface or board design.

Parameter Comparison

Engineering Selection Recommendations

The 51772-007LF is a direct functional equivalent to the 51772-007. Both connectors share identical electrical and mechanical specifications across all critical parameters that determine connector compatibility and performance.

The primary distinction between these parts is product lifecycle status and regulatory compliance:

• The 51772-007 is classified as obsolete, indicating end-of-life status and limited availability.
• The 51772-007LF is classified as active, ensuring ongoing manufacturing support and supply chain availability.
• The 51772-007LF is RoHS compliant, whereas the 51772-007 is RoHS non-compliant.
• The 51772-007LF includes REACH compliance status documentation.

For new designs or ongoing production requiring this connector type, the 51772-007LF is the appropriate selection. For legacy system maintenance where the original 51772-007 is specified, the 51772-007LF provides full electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 51772-007LF be used as a direct replacement for the 51772-007?

A: Yes. The 51772-007LF is electrically and mechanically equivalent to the 51772-007. All connector parameters, including position count, pitch, mounting type, contact configuration, and operating specifications, are identical. No board redesign or connector interface modification is required.

Q: What is the difference between the 51772-007 and 51772-007LF?

A: The primary differences are product status and regulatory compliance. The 51772-007 is obsolete and RoHS non-compliant. The 51772-007LF is active and RoHS compliant. Both parts are functionally identical for connector applications.

Q: Why is the 51772-007 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production of this part number. The 51772-007LF represents the current active equivalent within the PwrBlade® series.

Q: Are there packaging differences between these parts?

A: The 51772-007LF is supplied in tray packaging. Packaging specifications for the 51772-007 are not provided in the technical data.

Q: Does the RoHS compliance difference affect connector performance?

A: RoHS compliance relates to material composition and regulatory requirements, not electrical or mechanical performance. Both parts meet the same UL94 V-0 flammability rating and operating specifications. RoHS compliance is a regulatory and supply chain consideration for new designs and procurement.

Q: What is the contact finish specification for both parts?

A: Both connectors feature gold or gold GXT™ contact finish with a thickness of 30.0µin (0.76µm), ensuring consistent electrical performance and corrosion resistance.
