Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51772-001 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Position count: 36 positions
• Pitch specification: 0.100" (2.54mm)
• Row configuration: 4 rows
• Mounting method: Board edge, through-hole, right-angle orientation
• Contact layout: 28 signal and 8 power positions
• Termination method: Solder
• Contact finish and thickness: Gold or Gold, GXT™ at 30.0µin (0.76µm)
• Physical color: Black
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C ~ 105°C
• Mechanical features: Board lock and guide pin

Parts meeting all these criteria are classified as direct substitutes. Variations in product status, packaging format, or compliance certifications do not affect functional or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 51772-001LF is a direct functional and mechanical equivalent to the 51772-001. Both parts share identical electrical and physical specifications across all critical parameters that determine connector compatibility and performance.

The primary distinction between these parts is product status and compliance posture. The 51772-001 is classified as obsolete, while the 51772-001LF maintains active product status. The 51772-001LF additionally carries RoHS compliance certification and REACH affected status, making it suitable for applications subject to environmental and regulatory requirements.

For new designs or ongoing production requiring compliance with RoHS directives, the 51772-001LF is the appropriate selection. For legacy system support where RoHS compliance is not a requirement, either part satisfies the functional specification.

Frequently Asked Questions (FAQ)

Q: Are the 51772-001 and 51772-001LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch, row configuration, mounting method, and physical dimensions. They are direct mechanical substitutes.

Q: What is the significance of the "LF" designation in the 51772-001LF part number?

A: The "LF" suffix indicates lead-free construction and RoHS compliance. This designation reflects the material composition and environmental compliance status of the connector.

Q: Can the 51772-001 be used in applications requiring RoHS compliance?
