Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSB08M-13 is based on the following critical electrical and mechanical parameters:

• Diode Type: Single Phase bridge rectifier topology
• Voltage Rating: 1 kV peak reverse voltage (Vrrm)
• Current Capability: Minimum 800 mA average rectified current
• Forward Voltage: Maximum 1.1 V @ rated current
• Reverse Leakage: Maximum 5 µA @ 1000 V
• Operating Temperature: -55°C ~ 150°C junction temperature range
• Mounting: Surface mount configuration
• Package Form Factor: 4-SMD footprint compatibility
• Compliance: RoHS3 and REACH status

The ABS10A-13 meets all substitution criteria with equivalent electrical performance and enhanced current rating (1 A vs. 800 mA), providing design margin while maintaining identical voltage ratings and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The ABS10A-13 is the direct substitute for the obsolete MSB08M-13. Selection is based on the following factors:

• Product Status: The MSB08M-13 is obsolete; the ABS10A-13 is active and available in high volume (20,206 pcs in stock vs. 671 pcs for the original part).
• Electrical Equivalence: Both parts share identical voltage ratings (1 kV), temperature range (-55°C ~ 150°C), and reverse leakage characteristics (5 µA @ 1000 V). The ABS10A-13 provides higher current capability (1 A vs. 800 mA), offering design margin without performance compromise.
• Compliance: Both parts are RoHS3 compliant. The ABS10A-13 has improved REACH status (unaffected vs. affected), reducing regulatory risk.
• Package Compatibility: Both use 4-SMD surface mount footprints. The ABS10A-13 package designation (4-SOPA) differs from the original (4-MSB), but the physical footprint remains compatible for PCB placement.

Frequently Asked Questions (FAQ)

Q: Can the ABS10A-13 directly replace the MSB08M-13 on existing PCBs?

A: Yes. Both parts use compatible 4-SMD surface mount footprints. The ABS10A-13 is physically and electrically compatible with the MSB08M-13 footprint and can be placed without PCB redesign.

Q: What is the difference between the 4-MSB and 4-SOPA package designations?

A: These are supplier-specific package codes for the same 4-SMD form factor. The 4-SOPA designation (used by ABS10A-13) and 4-MSB designation (used by MSB08M-13) refer to identical physical packages with compatible lead spacing and mounting requirements.

Q: Is the higher current rating (1 A vs. 800 mA) of the ABS10A-13 a concern for circuit compatibility?

A: No. Higher current rating provides design margin and does not create compatibility issues. The ABS10A-13 will operate safely in circuits designed for 800 mA operation.

Q: What is the significance of the REACH status difference?

A: The ABS10A-13 has REACH Unaffected status, indicating it does not contain substances of very high concern (SVHC) listed under REACH regulations. The MSB08M-13 has REACH Affected status. For new designs and long-term supply chain stability, the ABS10A-13 is preferred.

Q: Are there any thermal or reliability differences between these parts?

A: Both parts share identical operating temperature ranges (-55°C ~ 150°C) and reverse leakage specifications (5 µA @ 1000 V). No thermal or reliability differences exist between the two parts.

Q: Why is the MSB08M-13 obsolete?

A: The MSB08M-13 is obsolete due to product lifecycle management by Diodes Incorporated. The ABS10A-13 represents the current active product line for this rectifier category and is the recommended replacement.
