Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 51952-001 is determined by strict equivalence across the following critical parameters:

Connector type, style, and configuration (Header, Male Pins and Blades, Blade Power) Position count and contact layout (26 positions, 24 Signal + 2 Power) Pitch spacing (0.100" / 2.54mm) Row configuration (4 rows) Mounting and termination method (Through Hole, Solder) Contact finish specification (Gold or Gold, GXT™ at 30.0µin thickness) Physical color and material properties (Black, UL94 V-0) Operating temperature range (-20°C ~ 105°C) Moisture sensitivity classification (MSL 1)

The 51952-001LF qualifies as a direct substitute based on full alignment with all critical parameters. The primary distinction is product status and regulatory compliance, not functional or mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 51952-001LF is the direct functional equivalent of the 51952-001. Both parts share identical electrical and mechanical specifications across all critical parameters that determine connector compatibility and performance.

Selection between these parts should be based on the following factors:

For new designs or production requiring regulatory compliance, the 51952-001LF is the appropriate choice. It carries Active product status and RoHS Compliant certification, ensuring long-term availability and alignment with current environmental regulations.

For legacy system maintenance or retrofit applications where the original 51952-001 is specified, the 51952-001LF provides full functional interchangeability without design modification. The connector geometry, pin configuration, contact layout, and electrical characteristics are identical.

The 51952-001LF is supplied in Tray packaging, which may differ from original procurement specifications. Verify packaging requirements for your application before final part selection.
