Amphenol ICC 71920-306 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71920-306 is a 6-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features gold-plated mating contacts and tin-plated posts, with a push-pull fastening mechanism and UL94 V-0 flammability rating.

The 71920-306 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Engineering Selection Recommendations

71920-306LF is the direct active equivalent of the obsolete 71920-306. Both parts maintain identical electrical and mechanical specifications, including single-row configuration, 6-position layout, and 0.100" pitch. The primary distinction is product status: 71920-306LF is active and RoHS compliant, whereas the original 71920-306 is obsolete and RoHS non-compliant. For new designs and production requiring RoHS compliance, 71920-306LF is the appropriate selection.

71991-303LF is a functional substitute with a critical geometric difference: it features a 2-row configuration instead of the single-row design of the 71920-306. While both maintain the same 0.100" pitch, contact finish specifications, and fastening mechanism, the dual-row layout results in different mating stacking heights (11.04mm for 71991-303LF versus standard single-row dimensions for 71920-306). This part is suitable only for applications where the 2-row configuration is compatible with the PCB layout and mating connector design.

Both substitute parts are manufactured by Amphenol ICC (FCI) within the Dubox™ series and maintain UL94 V-0 flammability ratings and identical contact materials and finishes.

Frequently Asked Questions (FAQ)

Q: Can 71920-306LF be used as a direct replacement for 71920-306?

A: Yes. The 71920-306LF maintains all critical electrical and mechanical parameters of the 71920-306, including connector type, position count, pitch, mounting method, and contact specifications. The primary difference is that 71920-306LF is an active product with RoHS compliance, whereas 71920-306 is obsolete and RoHS non-compliant.

Q: What is the key difference between 71920-306LF and 71991-303LF?

A: The primary difference is the row configuration. The 71920-306LF maintains a single-row, 6-position layout identical to the original 71920-306. The 71991-303LF features a 2-row configuration with 3 positions per row, resulting in different physical dimensions and mating stacking heights. Substitution of 71991-303LF requires verification that the PCB layout and mating connector accommodate the dual-row geometry.

Q: Are all three parts compatible with the same mating connector?

A: The 71920-306 and 71920-306LF are compatible with the same single-row mating connectors. The 71991-303LF, due to its 2-row configuration, requires a mating connector designed for dual-row receptacles and is not interchangeable with single-row designs.

Q: What packaging options are available?

A: The 71920-306 is supplied in bulk packaging. Both active substitutes, 71920-306LF and 71991-303LF, are supplied in tube packaging.

Q: Are there RoHS compliance considerations for these parts?

A: The original 71920-306 is RoHS non-compliant. Both substitute parts, 71920-306LF and 71991-303LF, are RoHS compliant, making them suitable for applications requiring RoHS adherence.
