Substitute Part Grouping Explanation

Substitution eligibility for the BA159GP-AP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): Tolerance range 250 ns to 500 ns
• Current - Reverse Leakage @ Vr: Range 1 µA to 6 µA @ 1000 V
• Operating Temperature - Junction: Minimum -65°C, maximum 150°C or higher
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz

The identified substitute parts meet all critical matching parameters and fall within acceptable variation ranges for secondary electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

BA159GP-AP (Micro Commercial Co): Primary component with Active product status. ROHS3 compliant and REACH unaffected. Reverse recovery time of 250 ns provides fastest switching performance among the three options. Suitable for applications requiring minimal switching losses.

1N4948GP-E3/54 (Vishay General Semiconductor - Diodes Division): Active product status with ROHS3 compliance and REACH unaffected. Extended operating temperature range to 175°C provides thermal margin beyond the primary part. Reverse recovery time of 500 ns is acceptable within fast recovery classification. SUPERECTIFIER® series designation indicates optimized performance characteristics. Lower reverse leakage current (1 µA) compared to primary part.

FR107-T/B (MDD): Active product status with RoHS compliance and REACH unaffected. Reverse recovery time of 500 ns meets fast recovery specification. Reverse leakage current of 6 µA remains within acceptable variation. Operating temperature range matches primary part at -65°C to 150°C. Highest inventory availability among substitute options.

All three parts maintain identical critical electrical ratings and mechanical compatibility. Selection between substitutes is based on availability, thermal requirements, switching speed requirements, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the 1N4948GP-E3/54 replace the BA159GP-AP in all applications?

A: Yes. The 1N4948GP-E3/54 meets all critical electrical parameters (1000 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage) and maintains identical package compatibility (DO-41/DO-204AL through-hole). The extended operating temperature range to 175°C provides additional thermal capability. Reverse recovery time of 500 ns remains within the fast recovery classification.

Q: What is the difference in reverse recovery time between these parts?

A: The BA159GP-AP has a reverse recovery time of 250 ns, while both the 1N4948GP-E3/54 and FR107-T/B have 500 ns. All three parts meet the fast recovery specification (≤ 500ns, > 200mA). The 250 ns specification of the primary part indicates faster switching transitions, which may reduce switching losses in high-frequency applications.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use the DO-41 axial through-hole package (DO-204AL designation). Physical dimensions and lead spacing are identical, enabling direct board-level substitution without layout modifications.

Q: Which substitute part has the lowest reverse leakage current?

A: The 1N4948GP-E3/54 has the lowest reverse leakage current at 1 µA @ 1000 V, compared to 5 µA for the BA159GP-AP and 6 µA for the FR107-T/B. Lower reverse leakage reduces standby power consumption in DC blocking applications.

Q: Do all parts meet RoHS compliance requirements?

A: The BA159GP-AP and 1N4948GP-E3/54 are ROHS3 compliant. The FR107-T/B is RoHS compliant. Both compliance levels satisfy standard RoHS directives. REACH status is unaffected for all three parts.

Q: What is the moisture sensitivity level for these diodes?

A: All three parts have Moisture Sensitivity Level (MSL) 1, classified as Unlimited. This indicates no moisture-related storage or handling restrictions apply to these components.

Q: Can these parts be used in high-temperature applications?

A: The BA159GP-AP and FR107-T/B are rated to 150°C junction temperature. The 1N4948GP-E3/54 extends to 175°C, providing 25°C additional thermal margin. Selection depends on specific application temperature requirements.
