Substitute Part Grouping Explanation

Substitute parts for the LB1863M-TLM-E are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Output Configuration: Half Bridge (2)
• Current - Output / Channel: 1.5A
• Voltage - Supply: 6.4V ~ 7V
• Voltage - Load: 24V
• Operating Temperature Range: -30°C ~ 80°C (TA)
• Load Type: Inductive
• Package / Case: 14-LSOP (0.173", 4.40mm Width)
• Fault Protection: Over Temperature
• Technology: Bipolar

Parts meeting all these parameters are classified as direct substitutes and maintain full functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LB1863M-TLM-H is a direct substitute for the LB1863M-TLM-E. Both parts share identical electrical specifications, mechanical packaging, and regulatory compliance status. The LB1863M-TLM-H maintains ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity in applications currently using the LB1863M-TLM-E.

Both parts are classified as obsolete products. Selection between these variants should be based on current inventory availability and supply chain considerations rather than technical differentiation.

Frequently Asked Questions (FAQ)

Q: Can the LB1863M-TLM-H replace the LB1863M-TLM-E in existing designs?

A: Yes. The LB1863M-TLM-H is a direct substitute with identical electrical and mechanical parameters. No design modifications are required for PCB layout, signal routing, or power delivery circuits.

Q: Are there differences in package dimensions between these parts?

A: No. Both parts use the 14-LSOP package with identical dimensions of 0.173" width and 4.40mm overall width. PCB footprints are interchangeable.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the LB1863M-TLM-E and LB1863M-TLM-H operate across -30°C to 80°C (TA), maintaining identical thermal performance characteristics.

Q: Are there compliance differences between these substitutes?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: What is the significance of the different suffix designations (-TLM-E versus -TLM-H)?

A: The suffix designations indicate different manufacturing batches or date codes from onsemi. The electrical and mechanical specifications remain identical across these variants.
