Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB1836ML-TLM-E is determined by the following critical parameters:

• Functional Classification: Motor driver IC with equivalent output stage configuration
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status
• Export Classification: EAR99 designation
• Tariff Classification: HTSUS 8542.39.0001
• Electrical Function: Driver capability for motor control applications

The TC78H621FNG,EL from Toshiba Semiconductor and Storage qualifies as a substitute based on matching functional classification as a motor driver, equivalent regulatory compliance status, and identical tariff and export classifications.

Parameter Comparison

Engineering Selection Recommendations

The TC78H621FNG,EL is an active product with current manufacturing support, whereas the LB1836ML-TLM-E is obsolete. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent applications.

The TC78H621FNG,EL offers improved moisture sensitivity characteristics (MSL 1 versus MSL 3), reducing handling and storage constraints. Both parts share identical export classification (EAR99) and tariff codes (HTSUS 8542.39.0001), ensuring consistent regulatory treatment.

Package differences exist between the 14SOIC (LB1836ML-TLM-E) and 16-TSSOP (TC78H621FNG,EL) configurations, requiring PCB layout modification. The substitute part provides documented electrical specifications including supply voltage range (2.7V ~ 5.5V), load voltage range (2.5V ~ 15V), and output current capability (1.1A), enabling precise circuit design validation.

Frequently Asked Questions (FAQ)

Q: Why is the LB1836ML-TLM-E being discontinued? A: The LB1836ML-TLM-E is listed as obsolete. The TC78H621FNG,EL is an active product with ongoing manufacturing support.

Q: What are the key differences between these parts? A: The primary differences are package type (14SOIC versus 16-TSSOP), moisture sensitivity level (MSL 3 versus MSL 1), and documented electrical specifications. Both maintain equivalent regulatory compliance.

Q: Can I use the TC78H621FNG,EL as a direct replacement? A: The TC78H621FNG,EL functions as a motor driver substitute. However, the package change from 14SOIC to 16-TSSOP requires PCB redesign. Verify that the documented electrical specifications (2.7V ~ 5.5V supply, 1.1A output current, -30°C ~ 85°C operating range) align with your application requirements.

Q: Are both parts RoHS compliant? A: Yes, both the LB1836ML-TLM-E and TC78H621FNG,EL are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity difference? A: The LB1836ML-TLM-E has MSL 3 (168 hours), while the TC78H621FNG,EL has MSL 1 (unlimited). MSL 1 provides less restrictive handling and storage requirements.

Q: Are export classifications identical? A: Yes, both parts are classified as EAR99 and share the same HTSUS code (8542.39.0001).
