Key Parameters

Substitute Part Grouping Explanation

The substitute part 71920-309LF is classified as a direct equivalent based on the following critical parameters that determine functional and mechanical interchangeability:

Matching Parameters:

• Connector type: Receptacle, Bottom or Top Entry
• Number of positions: 9
• Pitch - Mating: 0.100" (2.54mm)
• Contact type: Female Socket
• Mounting type: Through Hole
• Termination: Solder
• Contact finish - Mating: Gold (30.0µin / 0.76µm)
• Contact finish - Post: Tin (78.7µin / 2.00µm)
• Insulation material: Thermoplastic, Glass Filled
• Material flammability rating: UL94 V-0
• Insulation color: Blue
• Insulation height: 0.335" (8.51mm)
• Contact length - Post: 0.122" (3.10mm)
• Fastening type: Push-Pull
• Series: Dubox™

Distinguishing Difference: The primary distinction is product status and regulatory compliance. The 71920-309LF is an active product with RoHS compliance, whereas the 71920-309 is obsolete and RoHS non-compliant. The packaging differs (Tube for 71920-309LF versus unspecified for 71920-309).

Parameter Comparison

Engineering Selection Recommendations

The 71920-309LF is the direct functional equivalent of the obsolete 71920-309. All electrical and mechanical parameters are identical, ensuring pin-for-pin and footprint compatibility. The substitute part is currently in active production status, providing assured supply availability.

For new designs and production applications, the 71920-309LF is the appropriate selection. This part carries RoHS compliance certification, meeting current regulatory requirements for electronic components in most jurisdictions. The obsolete 71920-309 should be replaced with the 71920-309LF in all new procurement and design activities.

For existing field service or legacy system maintenance where the original 71920-309 is specified, the 71920-309LF provides functional equivalence without design modification or PCB rework.

Frequently Asked Questions (FAQ)

Q: Are the 71920-309 and 71920-309LF mechanically interchangeable?
