Substitute Part Grouping Explanation

Substitution of the DB107SP-HF is determined by electrical and mechanical parameter equivalence. The primary substitute identified is the DB107S-HF, which maintains identical electrical specifications across all critical parameters: 1 kV peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, and 10 µA reverse leakage current at 1000 V. Both parts operate within the same temperature range (-55°C to 150°C) and utilize identical surface mount packaging (4-SMD, Gull Wing, DBS).

The key differentiator between the main part and its substitute is product status and packaging format. The DB107SP-HF is obsolete, while the DB107S-HF is active and available in higher inventory quantities. The DB107S-HF carries RoHS3 compliance and REACH unaffected status, with MSL rating of 1 (Unlimited), providing superior supply chain reliability.

Substitution eligibility is strictly limited to parts matching all of the following parameters:

• Single Phase diode type
• Standard technology classification
• 1 kV peak reverse voltage rating
• 1 A average rectified current capacity
• 1.1 V maximum forward voltage at 1 A
• 10 µA reverse leakage at 1000 V
• Surface mount mounting type
• 4-SMD, Gull Wing package configuration

Parameter Comparison

Engineering Selection Recommendations

The DB107S-HF is the direct equivalent substitute for the DB107SP-HF. Both parts are manufactured by Comchip Technology and share identical electrical and mechanical specifications. The DB107S-HF is the preferred selection for new designs and component replacement due to its active product status and higher inventory availability (982 Pcs vs. 737 Pcs).

The DB107S-HF carries RoHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling, reducing supply chain complexity.

Selection of the DB107S-HF eliminates obsolescence risk associated with the DB107SP-HF while maintaining full electrical and mechanical compatibility. Both parts are suitable for identical circuit applications requiring single-phase bridge rectification at 1 kV and 1 A ratings.

Frequently Asked Questions (FAQ)

Q: Can the DB107S-HF directly replace the DB107SP-HF in existing designs?

A: Yes. The DB107S-HF is electrically and mechanically equivalent to the DB107SP-HF. Both parts share identical voltage ratings (1 kV), current capacity (1 A), forward voltage characteristics (1.1 V @ 1 A), reverse leakage specifications (10 µA @ 1000 V), operating temperature range (-55°C to 150°C), and package configuration (4-SMD, Gull Wing, DBS). No circuit modifications are required.

Q: What is the primary reason for substituting the DB107SP-HF?

A: The DB107SP-HF is classified as obsolete. The DB107S-HF is the active equivalent part, ensuring long-term supply availability and compliance with current regulatory standards including RoHS3 and REACH requirements.

Q: Are there differences in packaging between these parts?

A: Both parts use identical 4-SMD, Gull Wing surface mount packaging (DBS). The primary packaging difference is the distribution format: the DB107SP-HF is supplied in standard packaging, while the DB107S-HF is supplied in Tube packaging. This does not affect electrical or mechanical compatibility.

Q: What are the critical electrical parameters for substitution?

A: Substitution requires matching of the following parameters: 1 kV peak reverse voltage, 1 A average rectified current, 1.1 V maximum forward voltage at 1 A, and 10 µA reverse leakage current at 1000 V. The DB107S-HF meets all these specifications.

Q: Does the DB107S-HF meet environmental compliance requirements?

A: Yes. The DB107S-HF is RoHS3 compliant and REACH unaffected. It carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What is the inventory status of the substitute part?

A: The DB107S-HF has 982 Pcs of new original stock available, compared to 737 Pcs for the obsolete DB107SP-HF, providing improved supply chain reliability.
