Parameter Comparison

Engineering Selection Recommendations

LV11961HA-AH (onsemi): This substitute maintains the closest alignment with the LB11961-TLM-H-W within the onsemi product family. Both devices share identical REACH and ECCN classifications, and the LV11961HA-AH carries ROHS3 compliance. The LV11961HA-AH features Bi-CMOS technology with 1A output current capability and operates across a 3.6V to 16V supply range. However, the LV11961HA-AH is also obsolete, making it suitable only for legacy system maintenance or short-term procurement windows.

TA7267BP(O) (Toshiba): This through-hole mounted alternative provides 1A output current and operates across a 6V to 18V supply range. The TA7267BP(O) is an active product with RoHS compliance and MSL 1 rating, offering superior moisture tolerance compared to the main part. The 7-SIP package differs from the 14-HSSOP, requiring PCB layout modifications. This option is suitable for applications with lower operating temperature requirements (-30°C to 75°C).

TA7291FG(O,EL) (Toshiba): This surface-mount alternative in a 16-BSOP package delivers 400mA output current and supports a 4.5V to 20V supply range. The TA7291FG(O,EL) is an active product with RoHS compliance and MSL 1 rating. The higher voltage ceiling (20V) and integrated heat tabs provide thermal management advantages. Package footprint differs from the 14-HSSOP, requiring design verification.

TA7291SG(O,J) (Toshiba): This through-hole mounted variant shares the same electrical specifications as the TA7291FG(O,EL) but in a 9-SIP package. The TA7291SG(O,J) is an active product with RoHS compliance and MSL 1 rating. This option is suitable for applications prioritizing through-hole assembly or legacy PCB designs.

All Toshiba alternatives carry active product status and superior moisture sensitivity ratings, providing long-term availability and supply chain stability compared to obsolete onsemi options.

Frequently Asked Questions (FAQ)

Q: Can the LV11961HA-AH directly replace the LB11961-TLM-H-W without PCB modifications?

A: The LV11961HA-AH uses the same 14-HSSOP package family as the LB11961-TLM-H-W, making it a pin-compatible substitute. However, both devices are obsolete. Verify pinout compatibility and thermal requirements before implementation.

Q: What are the key differences between onsemi and Toshiba motor driver options?

A: onsemi options (LB11961-TLM-H-W, LV11961HA-AH) are obsolete but feature Bi-CMOS technology. Toshiba options (TA7267BP, TA7291FG, TA7291SG) are active products with Bipolar technology, RoHS compliance, and MSL 1 ratings. Toshiba alternatives offer superior long-term availability and moisture tolerance.

Q: Which substitute is best for new designs?

A: For new designs, select from active Toshiba products: TA7291FG(O,EL) for surface-mount applications or TA7291SG(O,J) for through-hole assembly. Both offer 4.5V to 20V supply range, RoHS compliance, and MSL 1 ratings. The TA7267BP(O) is suitable if 1A output current is required and 6V to 18V supply range is acceptable.

Q: Are package changes required when substituting with Toshiba alternatives?

A: Yes. The TA7267BP(O) uses a 7-SIP package, TA7291FG(O,EL) uses a 16-BSOP package, and TA7291SG(O,J) uses a 9-SIP package. All differ from the original 14-HSSOP. PCB layout and schematic modifications are necessary.

Q: What is the current output difference between substitute parts?

A: The LV11961HA-AH and TA7267BP(O) deliver 1A per channel. The TA7291FG(O,EL) and TA7291SG(O,J) deliver 400mA per channel. Select based on motor load requirements.

Q: Do all substitutes meet the same compliance standards?

A: All substitutes carry EAR99 and HTSUS 8542.39.0001 classifications. Toshiba options are RoHS compliant with MSL 1 ratings. The LV11961HA-AH is ROHS3 compliant with MSL 3 rating. Verify compliance requirements for your application.

Q: What is the operating temperature range difference?

A: The LV11961HA-AH operates from -40°C to 150°C (junction temperature). Toshiba alternatives operate from -30°C to 75°C (ambient temperature). Select based on thermal environment requirements.
