Engineering Selection Recommendations

The KBP306G is the active equivalent for the obsolete KBP305G C2. Selection of the KBP306G is supported by the following factors:

Product Status: The KBP306G maintains active product status with 1330 units in stock, ensuring availability for new designs and replacement applications. The KBP305G C2 is classified as obsolete with limited inventory.

Electrical Equivalence: Both components share identical voltage ratings (600 V peak reverse), current ratings (3 A average rectified), and forward voltage characteristics (1.1 V @ 3 A). The KBP306G exhibits lower reverse leakage current (5 µA versus 10 µA), representing improved performance within the same specification class.

Compliance: Both components are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The KBP306G is REACH Affected while the KBP305G C2 is REACH Unaffected; however, both maintain equivalent regulatory standing for industrial applications.

Mechanical Compatibility: Both components utilize through-hole mounting with KBP package form factors. Package case designations differ (4-SIP versus 4-ESIP), but both maintain KBP supplier device package compatibility for circuit board integration.

Frequently Asked Questions (FAQ)

Q: Can the KBP306G directly replace the KBP305G C2 in existing circuit designs?

A: Yes. The KBP306G meets all critical electrical parameters of the KBP305G C2, including voltage rating (600 V), current rating (3 A), forward voltage (1.1 V @ 3 A), and operating temperature range (-55°C ~ 150°C). Both components utilize through-hole mounting with KBP package compatibility.

Q: What is the difference between the 4-SIP and 4-ESIP package designations?

A: Both designations refer to 4-pin single in-line package configurations compatible with KBP form factor specifications. The package case difference does not affect electrical performance or circuit board mounting compatibility for standard through-hole applications.

Q: Does the lower reverse leakage current of the KBP306G (5 µA versus 10 µA) affect circuit design?

A: No. The reverse leakage current difference is within the standard performance envelope for bridge rectifiers in this voltage and current class. Both values are acceptable for power supply and rectification applications. The KBP306G represents improved performance characteristics within the same specification range.

Q: Are there compliance differences between the KBP305G C2 and KBP306G?

A: Both components are ROHS3 compliant with identical ECCN and HTSUS classifications. The KBP306G is REACH Affected while the KBP305G C2 is REACH Unaffected. This distinction does not affect component functionality or circuit compatibility.

Q: What inventory considerations apply to these components?

A: The KBP305G C2 is obsolete with 821 units in stock. The KBP306G is active with 1330 units available. For new designs and long-term applications, the KBP306G is the recommended selection based on active product status and sustained availability.
