Key Parameters

Substitute Part Grouping Explanation

The 91601-302LF serves as the direct substitute for the obsolete 91601-302. Substitution is valid based on identical electrical and mechanical parameters:

• Connector type, position count, and pitch remain unchanged
• Contact materials, finishes, and thicknesses are identical
• Mounting configuration and surface mount termination are preserved
• Insulation material and flammability rating match exactly
• Series designation (Dubox™) is maintained

The primary distinction is product status: 91601-302 is obsolete, while 91601-302LF is active. The "LF" suffix indicates RoHS compliance in the substitute part, whereas the original is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

The 91601-302LF is the direct functional equivalent for the obsolete 91601-302. All electrical and mechanical parameters are identical, ensuring pin-for-pin and footprint compatibility. The substitute part is currently in active production with higher inventory availability (2672 pcs vs. 970 pcs for the original).

For new designs or component replenishment, the 91601-302LF is the appropriate selection. The RoHS compliance status of the substitute part aligns with current regulatory requirements in automotive, industrial, and telecommunications applications. Both parts maintain identical REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can 91601-302LF be used as a direct replacement for 91601-302 in existing designs?

A: Yes. The 91601-302LF is electrically and mechanically identical to the 91601-302. Pin configuration, pitch, contact materials, finishes, and mounting footprint are unchanged. The connector will function identically in board-to-board applications.

Q: What is the significance of the "LF" suffix in 91601-302LF?

A: The "LF" designation indicates RoHS compliance. The substitute part meets RoHS requirements, whereas the original 91601-302 does not. This distinction is important for applications subject to RoHS regulations.

Q: Are there packaging differences between these parts?

A: The 91601-302 is supplied in unspecified packaging, while the 91601-302LF is supplied in bulk packaging. Both parts have identical MSL ratings (1 - Unlimited), indicating no special moisture handling requirements.

Q: What applications are these connectors suitable for?

A: Both parts are rated for automotive, general purpose, industrial, and telecommunications applications. The UL94 V-0 flammability rating supports use in safety-critical environments.

Q: Is there a performance difference between the gold and tin contact finishes?

A: The contact finishes serve different functions. Gold plating (30.0µin) on mating contacts provides corrosion resistance and low contact resistance. Tin plating (78.7µin) on posts provides solderable surfaces for PCB attachment. Both finishes are identical between the main part and substitute.
