Parameter Comparison

Engineering Selection Recommendations

The DF6A6.8FUT1G is the direct functional equivalent of the DF6A6.8FUT1. Both parts share identical electrical characteristics and mechanical compatibility. The primary distinction is product lifecycle status: the DF6A6.8FUT1 is obsolete, while the DF6A6.8FUT1G maintains active production status.

The DF6A6.8FUT1G additionally provides ROHS3 compliance, whereas the original part is RoHS non-compliant. For new designs or ongoing procurement requirements, the DF6A6.8FUT1G is the appropriate selection. The substitute part is available in Tape & Reel packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are DF6A6.8FUT1 and DF6A6.8FUT1G electrically interchangeable?

A: Yes. Both parts are identical in voltage rating (5V reverse standoff, 6.4V breakdown minimum), power dissipation (75W peak pulse), capacitance (40pF @ 1MHz), channel configuration (4 unidirectional), and operating temperature range (-55°C to 150°C).

Q: Can DF6A6.8FUT1G be used as a direct replacement in existing PCB designs?

A: Yes. The DF6A6.8FUT1G uses the same 6-TSSOP/SC-88/SOT-363 package and maintains identical pin configuration and electrical performance. No PCB layout modifications are required.

Q: What is the difference between the packaging formats?

A: The DF6A6.8FUT1 is supplied in bulk packaging, while the DF6A6.8FUT1G is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated pick-and-place assembly operations.
