Frequently Asked Questions (FAQ)

Q: Are the DF9B-25P-1V(20) and DF9B-25P-1V(32) electrically interchangeable?

A: Yes. Both parts are identical in electrical function, contact configuration, pitch, and signal integrity characteristics. The difference in part number suffix reflects packaging format only.

Q: What is the significance of the packaging difference between these parts?

A: The DF9B-25P-1V(20) uses standard packaging suitable for manual handling and small-quantity orders. The DF9B-25P-1V(32) uses Tape & Reel packaging, which is optimized for automated pick-and-place assembly and high-volume production environments.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance status does not alter electrical or mechanical performance. The compliance difference reflects manufacturing process changes and material composition. The DF9B-25P-1V(32) meets current environmental regulations, making it the preferred choice for new designs.

Q: Can I use the DF9B-25P-1V(32) as a direct replacement in existing PCB designs?

A: Yes. The DF9B-25P-1V(32) maintains identical footprint, height, and contact spacing. No PCB layout modifications are required for substitution.

Q: Why is the DF9B-25P-1V(20) marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The DF9B-25P-1V(32) represents the current active equivalent within the DF9 series.
