Key Parameters

Substitute Part Grouping Explanation

Substitution of the 91618-320 is determined by strict equivalence across the following critical parameters:

• Connector type and entry configuration (Receptacle, Bottom or Top Entry)
• Contact count and arrangement (40 positions, 2 rows)
• Pitch specifications (0.100" mating pitch, 0.100" row spacing)
• Mounting technology (Surface Mount)
• Contact material and finish (Gold-plated mating surface)
• Fastening mechanism (Push-Pull with board lock)
• Insulation properties (Thermoplastic, Glass Filled, UL94 V-0)
• Series designation (Dubox™)

The 91618-320LF meets all these criteria as an active equivalent within the same product series and manufacturer family.

Parameter Comparison

Engineering Selection Recommendations

The 91618-320LF is the direct functional equivalent of the obsolete 91618-320. Both components share identical electrical and mechanical specifications within the Dubox™ series. The primary distinction is product status: the 91618-320LF is active and currently manufactured, while the 91618-320 is obsolete.

For new designs and ongoing production requiring this connector type, the 91618-320LF is the appropriate selection. The substitute part maintains full compatibility with existing board layouts and mating components designed for the 91618-320.

Regulatory compliance differs between the two parts. The 91618-320LF carries RoHS compliance and REACH affected status, whereas the original part is RoHS non-compliant and REACH unaffected. Applications subject to RoHS or REACH requirements should specify the 91618-320LF.

Frequently Asked Questions (FAQ)

Q: Are the 91618-320 and 91618-320LF mechanically interchangeable?

A: Yes. Both connectors share identical dimensions, pitch spacing, mounting footprint, and contact configuration. The mated stacking height of 10.81mm is identical for both parts.

Q: What does the "LF" suffix indicate in the 91618-320LF part number?

A: The "LF" designation indicates lead-free compliance, reflecting the RoHS compliant status of this variant.

Q: Can I use the 91618-320LF as a direct replacement in existing assemblies designed for the 91618-320?

A: Yes. The 91618-320LF is a direct substitute with no design modifications required. All electrical and mechanical parameters are equivalent.

Q: What is the difference in packaging between these two parts?

A: The 91618-320 packaging is not specified in available documentation. The 91618-320LF is supplied in tube packaging.

Q: Are there any compliance considerations when switching from 91618-320 to 91618-320LF?

A: The 91618-320LF is RoHS compliant and REACH affected, whereas the 91618-320 is RoHS non-compliant and REACH unaffected. Applications operating under RoHS or REACH regulations should use the 91618-320LF.

Q: What is the current availability status of these parts?

A: The 91618-320 is obsolete with 918 pieces in stock. The 91618-320LF is active with 1173 pieces in stock.
