Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 91601-320 is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with exactly 20 positions
• Pitch & Spacing: 0.100" (2.54mm) mating pitch, single row
• Contact Configuration: Female socket contacts with gold mating finish and tin post finish
• Mounting & Termination: Surface mount with solder termination
• Mechanical Compatibility: Push-pull fastening, 10.81mm mated stacking height
• Material & Flammability: Thermoplastic glass-filled insulation, UL94 V-0 rating

The substitute part 91601-320LF meets all these criteria, differing only in packaging format and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 91601-320LF is the direct functional equivalent of the 91601-320. Both parts share identical electrical and mechanical specifications within the Dubox™ series. The primary distinctions are:

Product Status: The 91601-320 is obsolete, while the 91601-320LF maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: The 91601-320LF is RoHS compliant and REACH affected, meeting current environmental and hazardous substance regulations. The original 91601-320 is RoHS non-compliant and REACH unaffected, reflecting its legacy status.

Packaging: The 91601-320LF is supplied in tube packaging, whereas the 91601-320 uses bulk packaging. This difference affects handling and storage but does not impact functional performance.

For new designs or ongoing production requiring this connector type, the 91601-320LF is the appropriate selection due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 91601-320 and 91601-320LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including the 10.81mm mated stacking height, 0.275" (6.99mm) insulation height, and push-pull fastening mechanism. They are directly interchangeable in board-to-board applications.

Q: What is the significance of the "LF" suffix in the 91601-320LF part number?

A: The "LF" designation indicates lead-free construction, which correlates with RoHS compliance. The 91601-320LF meets RoHS requirements, whereas the original 91601-320 does not.

Q: Can the 91601-320 be used in new production designs?

A: The 91601-320 is obsolete and not recommended for new designs. The 91601-320LF should be used instead to ensure regulatory compliance and supply chain availability.

Q: Are there differences in electrical performance between these parts?

A: No. Both connectors use identical contact materials (phosphor bronze), contact finishes (gold mating, tin post), and insulation materials (thermoplastic, glass-filled). Electrical performance is equivalent.

Q: What packaging format should be specified for procurement?

A: The 91601-320LF is supplied in tube packaging. If bulk packaging is required, consult with the manufacturer regarding availability of alternative packaging options for this part number.

Q: Are both parts suitable for automotive, industrial, and telecommunications applications?

A: Yes. Both the 91601-320 and 91601-320LF are rated for automotive, general purpose, industrial, and telecommunications applications.
