Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3KBP02M-E4/72 is determined by the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Voltage - Peak Reverse (Max): 200 V minimum rating
• Current - Average Rectified (Io): 3 A minimum rating
• Mounting Type: Through Hole
• Package Category: 4-SIP form factor compatibility
• Technology: Standard bridge rectifier technology
• Operating Temperature Range: -55°C ~ 150°C minimum
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part GBL02-E3/51 meets all critical substitution criteria. Both parts share identical voltage and current ratings, operate across the same temperature range, maintain equivalent compliance certifications, and utilize compatible through-hole mounting configurations within the 4-SIP package family.

Parameter Comparison

Engineering Selection Recommendations

The GBL02-E3/51 is a direct functional equivalent to the 3KBP02M-E4/72. Both parts maintain identical electrical ratings for voltage and current specifications, operate across the same temperature range, and carry equivalent compliance certifications (ROHS3 Compliant, REACH Unaffected). The primary distinction is packaging designation (KBPM versus GBL) within the 4-SIP form factor family, which does not affect electrical performance or through-hole mounting compatibility.

Selection between these parts should be based on current availability and procurement status. The 3KBP02M-E4/72 is classified as obsolete, while the GBL02-E3/51 is discontinued at DiGi Electronics, indicating both parts face supply constraints. Forward-looking designs should evaluate additional substitute options from the GBL02 base product family for improved long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the GBL02-E3/51 directly replace the 3KBP02M-E4/72 in existing designs?

A: Yes. Both parts are single-phase bridge rectifiers with identical 200 V peak reverse voltage and 3 A average rectified current ratings. They share the same operating temperature range (-55°C ~ 150°C), mounting type (through hole), and compliance certifications. The 4-SIP package family accommodates both KBPM and GBL package designations without modification to PCB layouts.

Q: What is the significance of the different forward voltage specifications?

A: The 3KBP02M-E4/72 specifies 1.05 V @ 3 A, while the GBL02-E3/51 specifies 1.1 V @ 4 A. These measurements are taken at different current levels and represent normal variation within standard bridge rectifier technology. Both values fall within acceptable operating parameters for single-phase rectification applications.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). They are equivalent from a regulatory and environmental standpoint.

Q: Why are both parts listed as obsolete or discontinued?

A: The 3KBP02M-E4/72 is classified as obsolete, and the GBL02-E3/51 is discontinued at DiGi Electronics. This reflects the natural lifecycle of standard bridge rectifier components as manufacturing transitions to newer product lines. For designs requiring long-term component availability, evaluation of alternative bridge rectifier families with active production status is recommended.

Q: Does package designation affect electrical performance?

A: No. The KBPM and GBL package designations both represent 4-SIP through-hole configurations. Package designation identifies the physical form factor and supplier device package but does not alter electrical characteristics, ratings, or performance specifications.
