Product details

Board-to-Board Fit: Pitch and Stack Height

The 91601-304ALF: The mated stack height of 10.81 mm defines the z-axis clearance between parallel boards; check your enclosure height budget against this dimension before layout. Single-row, 4 circuits loaded all positions – this is a compact signal link for sensor, control, or low-pin-count telecom interfaces. The bottom or top entry style means the same part can serve as a mezzanine bottom-entry receptacle or a top-entry for a cable-to-board harness, giving layout flexibility.

Mating Finish and Cycle Life

In a telecom or automotive environment with quarterly reconnections, the gold interface provides decades of reliable contact. Phosphor bronze contact material with tin-plated solder posts – the tin finish on the termination side ensures good solder wetting during reflow, while the gold mating surface resists corrosion in the unmated state.

Frequently asked questions

Where can I buy 91601-304ALF and how do I get a price?

91601-304ALF is available through independent distribution. No stock-holding claim; sourced per order.

What is the difference between 91601-304ALF and 91601-304PLF?

Both are 4-position, 0.100" pitch, single-row Dubox™ receptacles. The -ALF has a 30.0 µinch gold mating finish; the -PLF uses a different plating (typically tin or lower gold thickness). Choose the -ALF for higher mating cycle life or corrosive environments.

Can 91601-304ALF be used for board-to-board connections?

Yes, its listed style is Board to Board. The bottom or top entry design and 10.81 mm mated stack height make it suitable for mezzanine or parallel-board interconnects.
