Substitute Part Grouping Explanation

Substitution of the KBP310-BP is determined by electrical and mechanical parameter equivalence across the following criteria:

  • Diode Type: Single Phase (identical)
  • Technology: Standard (identical)
  • Voltage - Peak Reverse (Max): 1 kV (identical)
  • Current - Average Rectified (Io): 3 A (identical)
  • Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A (identical)
  • Current - Reverse Leakage @ Vr: 10 µA @ 1000 V (identical)
  • Mounting Type: Through Hole (identical)
  • Package / Case: 4-SIP form factor (identical)
  • RoHS Status: ROHS3 Compliant (identical)
  • Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)

The KBP310G-BP meets all substitution criteria and is manufactured by the same supplier, Micro Commercial Co, with active product status.

Engineering Selection Recommendations

The KBP310G-BP is the direct equivalent for the obsolete KBP310-BP. Both components share identical electrical specifications and mounting characteristics. The KBP310G-BP offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, meeting regulatory requirements for industrial and commercial applications.

The KBP310G-BP features an extended operating temperature range (-55°C to 150°C versus -55°C to 125°C), providing additional thermal margin for demanding environments. The package designation differs (GBP versus KBPR), reflecting the supplier's internal classification, but both utilize the identical 4-SIP through-hole form factor.

Frequently Asked Questions (FAQ)

Q: Can KBP310G-BP directly replace KBP310-BP in existing designs?

A: Yes. The KBP310G-BP is electrically and mechanically equivalent to the KBP310-BP. Both components share identical voltage ratings (1 kV), current ratings (3 A), forward voltage characteristics (1.1 V @ 1 A), and reverse leakage specifications (10 µA @ 1000 V). The through-hole 4-SIP package footprint is identical, enabling direct PCB substitution.

Q: What is the difference between the KBPR and GBP package designations?

A: KBPR and GBP are internal supplier package classifications for the same 4-SIP through-hole form factor. Both designations refer to identical physical dimensions and pin configurations. The difference reflects manufacturing or distribution variants rather than functional or electrical differences.

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

A: Both the KBP310-BP and KBP310G-BP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity classification. The KBP310G-BP includes REACH Unaffected status. Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the KBP310-BP obsolete while KBP310G-BP remains active?

A: The KBP310G-BP represents the active production variant of the same electrical design. Obsolescence of the KBP310-BP reflects manufacturing consolidation or distribution changes by Micro Commercial Co, not a change in component performance or capability.

Q: Does the extended temperature range of KBP310G-BP affect compatibility?

A: No. The extended operating range (-55°C to 150°C for KBP310G-BP versus -55°C to 125°C for KBP310-BP) is a superset of the original specification. Applications designed for the KBP310-BP will operate within the KBP310G-BP's rated temperature envelope.
