Key Parameters

Substitute Part Grouping Explanation

Substitution for the 91601-310 is determined by strict equivalence across the following critical parameters:

• Connector configuration: 10-position receptacle with 0.100" (2.54mm) pitch
• Mounting technology: Surface mount solder termination
• Contact system: Female socket with gold mating finish and tin post finish
• Mechanical interface: Push-pull fastening, board-to-board style
• Physical dimensions: Insulation height 0.275" (6.99mm), mated stacking height 10.81mm
• Material compliance: UL94 V-0 flammability rating, thermoplastic glass-filled insulation

The 91601-310LF meets all these criteria as a direct substitute within the Dubox™ series, with the primary distinction being product status and regulatory compliance.

Engineering Selection Recommendations

The 91601-310LF is the direct functional equivalent of the 91601-310 for all electrical and mechanical applications. Selection between these parts should be based on the following factors:

For new designs and active production: The 91601-310LF is the appropriate choice. It maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance, supporting long-term supply chain stability and regulatory alignment.

For legacy system maintenance: The 91601-310 remains functionally compatible with existing installations. However, the 91601-310LF provides superior availability (1737 units in stock versus 692 units) and eliminates potential regulatory compliance gaps in updated documentation or certifications.

Regulatory considerations: The 91601-310LF's RoHS compliance and REACH-affected status reflect current environmental regulations. Organizations subject to these requirements should prioritize the 91601-310LF for all new applications.

Frequently Asked Questions (FAQ)

Q: Are the 91601-310 and 91601-310LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (0.100"), number of positions (10), mounting type (surface mount), fastening method (push-pull), and physical dimensions (10.81mm mated stacking height). They are direct mechanical substitutes.

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

A: The primary differences are product status and regulatory compliance. The 91601-310LF is an active product with RoHS compliance, while the 91601-310 is obsolete and RoHS non-compliant. Both maintain identical electrical and mechanical performance specifications.

Q: Can I use the 91601-310LF as a replacement in existing designs using the 91601-310?

A: Yes. The 91601-310LF is a direct substitute with no design modifications required. All contact finishes, pitch spacing, mounting footprint, and electrical characteristics remain identical.

Q: What does the "LF" suffix in 91601-310LF indicate?

A: The "LF" designation indicates lead-free compliance, reflecting the part's RoHS compliance status and environmental regulatory alignment.

Q: Are there any packaging differences between these parts?

A: The 91601-310LF is supplied in tube packaging. Packaging specifications for the 91601-310 are not provided in the technical data.

Q: Which part should I specify for new production orders?

A: Specify the 91601-310LF for all new production. It provides active product status, superior inventory availability, and regulatory compliance while maintaining complete functional equivalence to the 91601-310.
