Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51863-001 is determined by strict equivalence across the following critical parameters:

• Connector type: Receptacle with female sockets and blade sockets
• Number of positions: 30
• Pitch: 0.100" (2.54mm)
• Number of rows: 4
• Contact layout: 24 signal, 6 power
• Mounting type: Through hole
• Termination method: Solder
• Contact finish: Gold or Gold, GXT™
• Contact finish thickness: 30.0µin (0.76µm)
• Color: Black
• Flammability rating: UL94 V-0
• Operating temperature range: -20°C to 105°C
• Features: Board lock and guide pin

The 51863-001LF meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and RoHS compliance level.

Parameter Comparison

Engineering Selection Recommendations

The 51863-001LF is the direct functional equivalent of the 51863-001. Both connectors share identical electrical and mechanical specifications across all critical parameters. The 51863-001LF is preferred for new designs and ongoing procurement due to its active product status and RoHS compliance. The 51863-001 is classified as obsolete and should be replaced in active bill-of-materials documentation.

For applications requiring RoHS non-compliant components, the 51863-001 remains functionally equivalent to the 51863-001LF. However, availability of the obsolete part number may be limited to existing inventory channels.

Frequently Asked Questions (FAQ)

Q: Can the 51863-001LF be used as a direct replacement for the 51863-001?

A: Yes. The 51863-001LF is electrically and mechanically identical to the 51863-001 across all specified parameters, including connector type, position count, pitch, contact layout, termination method, and operating temperature range.

Q: What is the difference between the 51863-001 and 51863-001LF?

A: The primary differences are product status and RoHS compliance. The 51863-001 is obsolete and RoHS non-compliant, while the 51863-001LF is active and RoHS compliant. Packaging differs: the 51863-001LF is supplied in trays. All electrical and mechanical specifications are identical.

Q: Why is the 51863-001 classified as obsolete?

A: The 51863-001 has been superseded by the 51863-001LF, which offers improved compliance status and active manufacturing support.

Q: Are there any compatibility concerns when substituting the 51863-001LF for the 51863-001?

A: No compatibility concerns exist. Both parts are from the same PwrBlade® series with identical connector geometry, contact configuration, and mounting specifications.

Q: What does the "LF" suffix in 51863-001LF indicate?

A: The "LF" suffix indicates lead-free construction and RoHS compliance.

Q: Can the 51863-001 be used in new designs?

A: The 51863-001 is obsolete. New designs should specify the 51863-001LF to ensure long-term availability and compliance with current regulatory requirements.
