Key Parameters

Substitute Part Grouping Explanation

The substitute part 91900-21441LF maintains identical electrical and mechanical specifications to the main part number across all critical parameters: connector type, position count, pitch, row configuration, mounting method, contact finish type and thickness, stacking height, and board height. The substitution is valid because both parts share the same base product number (91900) and are functionally interchangeable at the component level.

The primary distinction between these parts is product status and regulatory compliance. The 91900-21441LF is the active production variant with RoHS compliance and REACH affected status, whereas the original 91900-21441 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing production, the 91900-21441LF is the appropriate selection. This part maintains full electrical and mechanical compatibility with the obsolete 91900-21441 while offering active product status and RoHS compliance. The LF variant satisfies modern regulatory requirements and ensures supply chain continuity through an active manufacturer product line.

The 91900-21441LF is supplied in tube packaging, which is standard for surface mount connector headers and supports automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the 91900-21441 and 91900-21441LF electrically interchangeable? A: Yes. Both parts share identical electrical specifications including 41 positions, 0.039" (1.00mm) pitch, 2-row configuration, and gold contact finish with 15.0µin thickness.
