Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB11852RV-TLM-H is determined by the following critical parameters:

• Motor Type Compatibility: Both main and substitute parts must support Brushless DC (BLDC) motor operation
• Package Compatibility: Identical 20-LFSOP surface mount package ensures PCB layout compatibility without redesign
• Interface Standard: PWM control interface must be maintained for signal compatibility
• Voltage Supply Range: Substitute must operate within or encompass the supply voltage requirements of the application
• Operating Temperature Range: Substitute must meet or exceed the thermal operating window
• Regulatory Compliance: REACH and ECCN classifications ensure supply chain and export compliance

The LV88551JA-AH qualifies as a substitute based on matching motor type (BLDC), identical package footprint (20-LFSOP), PWM interface compatibility, and overlapping voltage supply capability. Both parts share onsemi manufacturer origin, identical package dimensions, and equivalent regulatory status.

Engineering Selection Recommendations

The LV88551JA-AH presents a direct substitute for the LB11852RV-TLM-H based on the following engineering criteria:

Package and Footprint Compatibility: Both parts utilize the identical 20-LFSOP surface mount package with 0.173" width and 4.40mm dimensions. PCB layout and assembly processes require no modification.

Voltage Supply Consideration: The LV88551JA-AH operates across 6V–16V, which encompasses the upper voltage range (5.5V–16V) of the main part. Applications requiring the lower 4.5V–5.5V range must confirm LV88551JA-AH compatibility through datasheet review or supplier consultation.

Thermal Operating Window: The substitute part extends the lower temperature limit to -40°C (versus -30°C) and upper limit to 105°C (versus 95°C), providing broader thermal margin for demanding environments.

Regulatory and Compliance Status: Both parts maintain identical REACH Unaffected status and EAR99 ECCN classification, ensuring equivalent supply chain and export compliance.

Product Status: Both parts are classified as obsolete. Long-term availability should be confirmed with the manufacturer or authorized distributors prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the LV88551JA-AH directly replace the LB11852RV-TLM-H without PCB modification?
