BDR6170T
Ningbo Songle Relay Co., Ltd.
Needs validationmedium risk
BDR6170T is a plausible functional AS4950 alternate, but footprint and missing current data need review.
Best Alternatives to AS4950
AS4950 is an 8V-40V brushed DC motor driver in SOP8-PP. Alternatives need careful pinout, footprint, and current review.
AI replacement insight
Electrical riskmedium
BDR6170T matches 40V but lacks cont-current data.
Package riskhigh
Only PN7706 lists SOP8-PP, but it is lower rated.
Firmware risklow
PWM control is common where listed.
Sourcing riskmedium
Lifecycle data is limited.
Can it be replaced directly?
No pin-compatible AS4950 replacement is proven from the provided data.
Best replacement path
BDR6170T is the best functional candidate, pending pinout, footprint, and continuous-current checks.
Main risk
Pinout and package compatibility are not verified.
