Substitute Part Grouping Explanation

Substitution for the 89891-309 is determined by strict equivalence across the following critical parameters:

Connector geometry: 18 positions, 2 rows, 0.100" (2.54mm) pitch and row spacing
Electrical interface: Female socket contacts with gold mating finish
Mechanical interface: Through-hole solder termination, push-pull fastening
Physical properties: Thermoplastic glass-filled insulation, UL94 V-0 rating
Contact materials: Phosphor bronze with specified finish thicknesses

The substitute part 89891-309LF maintains identical electrical and mechanical specifications while differing in product status (active vs. obsolete) and RoHS compliance classification.

Engineering Selection Recommendations

The 89891-309LF serves as the direct substitute for the obsolete 89891-309. Both parts are manufactured by Amphenol ICC within the Dubox™ series and maintain identical electrical and mechanical specifications across all critical parameters including connector geometry, contact materials, termination method, and flammability rating.

The primary distinction between these parts is product status and regulatory compliance. The 89891-309LF is currently in active production status, whereas the 89891-309 is obsolete. Additionally, the 89891-309LF carries RoHS compliance certification, while the 89891-309 is classified as RoHS non-compliant. Both parts share identical moisture sensitivity levels and export classifications.

For new designs or system replacements, the 89891-309LF is the appropriate selection due to its active availability and RoHS compliance status. For legacy system maintenance requiring exact part matching, the 89891-309 remains functionally equivalent where procurement is possible.

Frequently Asked Questions (FAQ)

Q: Are the 89891-309 and 89891-309LF mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch spacing (0.100"), row configuration (2 rows, 18 positions), mounting type (through-hole), and contact geometry. They are direct mechanical substitutes.

Q: What is the difference between these two part numbers?
