Engineering Selection Recommendations

LB11961V-TLM-E (onsemi): This part is a parametric equivalent to the LB11961V-TLM-H with identical electrical specifications and package configuration. The primary distinction is product status: LB11961V-TLM-E is active, whereas the main part is obsolete. This part maintains the same interface type (Parallel), technology (Bipolar), and operating temperature range. It is the direct replacement for designs requiring no modification.

BD6995FV-GE2 (Rohm Semiconductor): This part is manufacturer-recommended as a substitute. It shares the same package footprint and half-bridge output configuration. However, it introduces parametric differences: PWM interface instead of Parallel, Bi-CMOS technology instead of Bipolar, and support for Brushless DC motors in addition to brushed DC operation. The output current is rated at 1.2A (higher than 1A), and the supply voltage range is 4.3V ~ 17V (slightly wider). Operating temperature extends to -40°C ~ 105°C, and MSL rating is 1 (Unlimited), indicating superior moisture handling. This part is suitable for designs that can accommodate interface and technology changes.

Frequently Asked Questions (FAQ)

Q: Can LB11961V-TLM-E be used as a direct replacement for LB11961V-TLM-H?

A: Yes. LB11961V-TLM-E is a parametric equivalent with identical electrical and mechanical specifications. No design modifications are required. Both parts are onsemi products with the same Parallel interface, Bipolar technology, and operating characteristics.

Q: What are the key differences between LB11961V-TLM-E and BD6995FV-GE2?

A: The primary differences are: (1) Interface type—LB11961V-TLM-E uses Parallel control, while BD6995FV-GE2 uses PWM; (2) Technology—LB11961V-TLM-E is Bipolar, BD6995FV-GE2 is Bi-CMOS; (3) Motor support—BD6995FV-GE2 supports both Brushless DC and Brushed DC, while LB11961V-TLM-E supports Brushed DC only; (4) Output current—BD6995FV-GE2 is rated at 1.2A versus 1A; (5) Operating temperature—BD6995FV-GE2 extends to -40°C ~ 105°C; (6) MSL rating—BD6995FV-GE2 has MSL 1 (Unlimited) versus MSL 3 (168 Hours).

Q: Is the 16-LSSOP package footprint identical across all three parts?

A: Yes. All three parts use the 16-LSSOP package with 0.173" width (4.40mm). PCB layout and footprint design remain unchanged.

Q: Can BD6995FV-GE2 replace LB11961V-TLM-H in a brushed DC motor application?

A: BD6995FV-GE2 supports brushed DC motor operation and meets the half-bridge output configuration requirement. However, the interface change from Parallel to PWM requires control circuit modifications. The higher output current (1.2A) and extended operating temperature range are compatible with the original specification.

Q: What is the significance of MSL rating differences?

A: LB11961V-TLM-H and LB11961V-TLM-E have MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. BD6995FV-GE2 has MSL 1 (Unlimited), indicating superior moisture resistance and less stringent storage requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. LB11961V-TLM-H, LB11961V-TLM-E, and BD6995FV-GE2 are all ROHS3 compliant and REACH unaffected.
