Parameter Comparison

Engineering Selection Recommendations

The 51935-002LF is the direct functional equivalent of the 51935-002. Both components share identical electrical and mechanical specifications, including connector type, position count, pitch, mounting configuration, and contact layout. The primary distinction lies in product lifecycle status and regulatory compliance.

The 51935-002 is classified as obsolete, indicating discontinued manufacturing and limited availability. The 51935-002LF maintains active product status with current manufacturing support. Additionally, the 51935-002LF achieves RoHS compliance and REACH compliance status, whereas the original part is RoHS non-compliant. For new designs or ongoing production requiring regulatory alignment with current environmental standards, the 51935-002LF is the appropriate selection.

Frequently Asked Questions (FAQ)
