Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3KBP02M-M4/51 is determined by the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Current Rating: 3 A average rectified current (Io)
• Voltage Rating: Peak reverse voltage capability must equal or exceed 50 V
• Mounting Type: Through-hole package for PCB integration
• Package Compatibility: 4-SIP form factor or equivalent pin configuration
• Temperature Range: Operating capability across -55°C to 150°C
• Compliance: ROHS3 compliance and MSL Level 1 rating

The substitute part GBL02-E3/51 meets these criteria with identical current rating, compatible mounting type, and equivalent temperature range. The higher voltage rating (200 V) of the substitute provides enhanced design margin while maintaining backward compatibility in applications originally specified for 50 V operation.

Parameter Comparison

Engineering Selection Recommendations

The GBL02-E3/51 serves as the primary substitute for the obsolete 3KBP02M-M4/51. Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring regulatory and environmental compatibility. The substitute part carries identical current and temperature specifications, with a higher peak reverse voltage rating that provides additional design margin without introducing incompatibility. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, ensuring consistent quality and performance characteristics.

The GBL02-E3/51 is currently listed as discontinued at DiGi Electronics, indicating limited availability. For applications requiring the 3KBP02M-M4/51, the GBL02-E3/51 remains the recommended electrical and mechanical equivalent where inventory permits.

Frequently Asked Questions (FAQ)

Q: Can the GBL02-E3/51 directly replace the 3KBP02M-M4/51 in existing designs?

A: Yes. Both parts share identical current ratings (3 A), operating temperature ranges (-55°C to 150°C), mounting type (through-hole), and 4-SIP package form factor. The higher voltage rating of the GBL02-E3/51 (200 V vs. 50 V) is compatible with applications originally specified for 50 V operation.

Q: What are the key differences between these two parts?

A: The primary difference is the peak reverse voltage rating: the 3KBP02M-M4/51 is rated for 50 V, while the GBL02-E3/51 is rated for 200 V. Forward voltage characteristics show minimal variation (1.05 V vs. 1.1 V at comparable current levels). All other electrical and mechanical parameters are equivalent.

Q: Are there package compatibility concerns?

A: No. Both parts use 4-SIP through-hole packages with identical pin configurations. The KBPM and GBL package designations refer to the same physical form factor and are directly interchangeable on PCBs designed for standard 4-SIP bridge rectifier modules.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 3KBP02M-M4/51 and GBL02-E3/51 are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited) moisture sensitivity ratings. They share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the 3KBP02M-M4/51 marked as obsolete?

A: The part is classified as obsolete by the manufacturer, indicating it is no longer in active production. The GBL02-E3/51 represents the current-generation equivalent from the same manufacturer and product line.
