Key Parameters

Substitute Part Grouping Explanation

Substitution of the DB107-G is determined by strict equivalence across the following electrical and mechanical parameters:

• Diode type classification (single phase)
• Rectification technology (standard)
• Peak reverse voltage rating (1 kV minimum)
• Average rectified current capacity (1 A minimum)
• Forward voltage characteristics (1.1 V @ 1 A maximum)
• Reverse leakage current specification (10 µA @ 1000 V maximum)
• Operating temperature range (-55°C to 150°C minimum)
• Through-hole mounting configuration
• 4-EDIP package footprint compatibility

The DB107 from MDD meets all specified electrical parameters and maintains identical package geometry, establishing it as a parametric equivalent for the obsolete DB107-G.

Parameter Comparison

Engineering Selection Recommendations

The DB107 from MDD is the direct parametric equivalent for the obsolete DB107-G. Both components share identical electrical specifications across all critical parameters: 1 kV peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, and 10 µA reverse leakage current. The mechanical footprint and through-hole mounting configuration are identical, enabling direct board-level substitution without layout modification.

The MDD DB107 maintains active product status with current manufacturing availability, whereas the Comchip DB107-G is obsolete. Both components satisfy RoHS compliance requirements. The MDD variant is suitable for direct replacement in applications previously specified for the DB107-G.

Frequently Asked Questions (FAQ)

Q: Can the DB107 from MDD be used as a direct replacement for the DB107-G?

A: Yes. The DB107 from MDD meets all electrical and mechanical specifications of the DB107-G. Both components are rated for 1 kV peak reverse voltage, 1 A average rectified current, and share identical 4-EDIP package geometry. Direct substitution is possible without circuit modification.

Q: Are there any differences in forward voltage characteristics between these parts?

A: No. Both the DB107-G and DB107 specify a maximum forward voltage of 1.1 V at 1 A, ensuring equivalent voltage drop performance in rectification circuits.

Q: What is the significance of the package designation 4-EDIP (0.321", 8.15mm)?

A: The 4-EDIP package is a four-lead through-hole configuration with a 0.321-inch (8.15mm) lead spacing. This standardized footprint ensures mechanical and electrical compatibility between the DB107-G and DB107 on printed circuit boards designed for either component.

Q: Does the active product status of the DB107 affect its suitability as a substitute?

A: No. Active product status indicates current manufacturing and availability, which is advantageous for procurement. The electrical and mechanical equivalence remains the determining factor for substitution suitability.

Q: Are both components RoHS compliant?

A: Yes. The DB107-G is ROHS3 Compliant, and the DB107 is RoHS Compliant. Both satisfy regulatory requirements for lead-free manufacturing and hazardous substance restrictions.
