LB1863M-MPB-E Equivalent & Substitute Parts

Part Overview

The LB1863M-MPB-E is a half bridge driver IC manufactured by onsemi, designed for DC motor control and general-purpose applications. This device integrates dual output channels in a 14-SOIC surface mount package with 1.5A per-channel output capability and over-temperature fault protection. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LB1863M-MPB-E is determined by strict equivalence across the following parameters:

• Output Configuration: Half Bridge (2) topology
• Current Rating: 1.5A per channel minimum
• Supply Voltage Range: 6.4V ~ 7V
• Load Voltage: 24V
• Package Type: 14-LSOP surface mount
• Operating Temperature Range: -30°C ~ 80°C
• Fault Protection: Over Temperature capability
• Load Type: Inductive load support
• Interface Type: Logic-level control

Parts meeting all these criteria are classified as direct functional equivalents. Variations in manufacturing date codes, RoHS compliance status, or moisture sensitivity levels do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LB1863M-TLM-H is a direct functional equivalent to the LB1863M-MPB-E. Both parts share identical electrical specifications, package geometry, and thermal characteristics. The primary distinction is RoHS compliance status: the LB1863M-TLM-H carries RoHS3 Compliant certification, while the main part does not specify RoHS status.

For new designs or procurement requiring RoHS compliance, the LB1863M-TLM-H is the appropriate selection. For legacy system maintenance or applications without RoHS requirements, either part is electrically and mechanically interchangeable. Both parts are classified as obsolete; inventory availability should be verified with the supplier before design commitment.

Frequently Asked Questions (FAQ)

Q: Can the LB1863M-TLM-H be used as a direct replacement for the LB1863M-MPB-E?

A: Yes. Both parts are manufactured by onsemi from the same base product (LB1863) and share identical electrical ratings, output configuration, current capacity, voltage specifications, operating temperature range, package type, and fault protection features. Pin-for-pin and functional compatibility is confirmed.

Q: What is the difference between these two part numbers?

A: The primary difference is the RoHS compliance certification. The LB1863M-TLM-H is RoHS3 Compliant, while the LB1863M-MPB-E does not specify RoHS status. All electrical and mechanical parameters are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 14-LSOP (14-SOIC/MFPS) surface mount package with identical 0.173" width and pinout configuration. PCB layout and footprint compatibility is guaranteed.

Q: Does the moisture sensitivity level affect substitution?

A: No. Both parts carry identical MSL rating of 3 (168 Hours). Storage and handling requirements are the same.

Q: Which part should be selected for new designs?

A: For applications requiring RoHS compliance, select the LB1863M-TLM-H. For legacy system support or non-RoHS applications, either part is suitable. Verify current inventory availability with your supplier, as both parts are classified as obsolete.
