Substitute Part Grouping Explanation

Substitution of the DMT3008LFDF-13 is determined by electrical and mechanical parameter equivalence within the N-Channel MOSFET category. The critical parameters that define substitutability are:

Drain-to-source voltage rating (Vdss): 30V
Continuous drain current capability (Id): 12A at 25°C
On-state resistance (Rds On): 10mOhm maximum at specified gate and drain conditions
Gate threshold voltage (Vgs(th)): 3V maximum
Package configuration: 6-UDFN with exposed pad (U-DFN2020-6 Type F)
Mounting technology: Surface mount
Operating temperature range: -55°C to 150°C

The DMT3008LFDF-7 is identified as a parametric equivalent substitute. Both parts share identical electrical specifications, thermal ratings, and physical packaging. The difference between these part numbers reflects manufacturing date codes or tape reel configurations, not functional or electrical divergence.

Engineering Selection Recommendations

Both the DMT3008LFDF-13 and DMT3008LFDF-7 are active production parts from Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

The DMT3008LFDF-13 carries 748 pieces in current inventory. The DMT3008LFDF-7 carries 129,080 pieces in current inventory, providing significantly greater availability for high-volume applications or extended lead-time mitigation.

Both parts maintain ROHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility across applications. The identical package configuration (6-UDFN Exposed Pad, U-DFN2020-6 Type F) and surface mount technology enable direct board-level substitution without design modification.
