Key Parameters

Substitute Part Grouping Explanation

The 91488-421LF qualifies as a direct substitute for the 91488-421 based on identical electrical and mechanical parameters:

• Connector type, contact configuration, and position count match exactly
• Pitch and row spacing specifications are identical (0.100" / 2.54mm)
• Mounting method, termination type, and fastening mechanism are unchanged
• Physical housing color and insulation material remain consistent
• Operating temperature range is maintained
• Shielded feature specification is preserved

The primary distinction between these parts is product status and regulatory compliance. The 91488-421LF is an active product with RoHS compliance and REACH applicability, whereas the 91488-421 is obsolete and RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 91488-421LF is the appropriate selection for new designs and ongoing production applications. This part maintains full electrical and mechanical compatibility with the obsolete 91488-421 while providing active product status and current regulatory compliance. The RoHS compliance of the 91488-421LF aligns with modern manufacturing and environmental standards, and its REACH applicability reflects current regulatory frameworks. Both parts share identical connector specifications, ensuring direct interchangeability in applications where the 0.100" pitch, 16-position, 2-row configuration is required.

Frequently Asked Questions (FAQ)

Q: Are the 91488-421 and 91488-421LF mechanically interchangeable?

A: Yes. Both parts feature identical connector type, position count, pitch, row spacing, mounting method, and fastening mechanism. They are mechanically interchangeable in all applications.

Q: What is the significance of the "LF" suffix in the part number?
