Key Parameters

Substitute Part Grouping Explanation

Substitution of the BA158-TP is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Package / Case: DO-204AL, DO-41, Axial
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A (or lower)
• Current - Reverse Leakage @ Vr: 5 µA @ 600 V (or lower)
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz (or lower)
• Operating Temperature - Junction: -65°C to 125°C (or wider range)

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Manufacturer Substitute (Packaging Variant): BA158GP-TP maintains identical electrical specifications and manufacturer lineage with modified packaging format.

Similar Manufacturer Substitute (Cross-Manufacturer): 1N4005-E3/54 provides electrical equivalence from an alternative manufacturer with minor parameter variations in recovery speed and forward voltage.

Parametric Equivalent (Electrical Match): BA158-E3/54 delivers matching electrical performance with allowable variations in reverse recovery time and junction capacitance.

Parameter Comparison

Engineering Selection Recommendations

BA158GP-TP (Direct Manufacturer Substitute): This part is the primary substitute for BA158-TP. It is manufactured by the same supplier (Micro Commercial Co), maintains identical electrical specifications, and carries active product status. The only difference is packaging format (Tape & Reel versus tube). This part is suitable for direct replacement in all applications where the BA158-TP was originally specified. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin compared to the main part.

BA158-E3/54 (Parametric Equivalent): This Vishay part provides electrical equivalence with ROHS3 compliance and active product status. It matches the BA158-TP in voltage rating, current rating, forward voltage, and recovery speed classification. The reverse recovery time is 250 ns (versus 150 ns for BA158-TP), and junction capacitance is 12 pF (versus 15 pF). These variations remain within acceptable tolerance for general-purpose rectification applications. This part is suitable for applications where fast recovery performance is required but the specific 150 ns specification is not critical.

1N4005-E3/54 (Similar Manufacturer Substitute): This Vishay part meets the voltage and current requirements with identical package specifications and ROHS3 compliance. However, it features standard recovery characteristics (>500 ns) rather than fast recovery, and forward voltage is lower at 1.1 V @ 1 A. This part is suitable only for applications where recovery speed is not a design constraint and lower forward voltage drop is beneficial. The operating temperature range extends to 150°C, providing thermal margin.

All substitute parts carry ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and handling requirements of the original BA158-TP.

Frequently Asked Questions (FAQ)

Q: Can BA158GP-TP be used as a direct replacement for BA158-TP?

A: Yes. BA158GP-TP is manufactured by the same supplier and maintains identical electrical specifications. The difference is packaging format (Tape & Reel versus tube). Both parts are rated for 600 V, 1 A, with 1.3 V forward voltage and 150 ns reverse recovery time. Mechanical fit in through-hole applications is identical.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Recovery speed refers to how quickly the diode transitions from conducting to blocking state. BA158-TP and BA158-E3/54 feature fast recovery (≤500 ns), while 1N4005-E3/54 features standard recovery (>500 ns). Fast recovery diodes are preferred in switching applications where reduced switching losses are required. Standard recovery diodes are suitable for linear rectification applications.

Q: Can 1N4005-E3/54 replace BA158-TP in all applications?

A: 1N4005-E3/54 is suitable only for applications where recovery speed is not a design constraint. It provides the same voltage and current ratings but uses standard recovery technology rather than fast recovery. If the original design relied on the 150 ns recovery time of BA158-TP, 1N4005-E3/54 is not appropriate.

Q: What does the difference in reverse recovery time (150 ns vs. 250 ns) mean for circuit performance?

A: Reverse recovery time affects switching losses and electromagnetic interference generation. Shorter recovery time (150 ns) results in lower switching losses and reduced EMI. The 250 ns recovery time of BA158-E3/54 is acceptable for general-purpose applications but may increase power dissipation in high-frequency switching circuits.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (BA158GP-TP, BA158-E3/54, and 1N4005-E3/54) are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance of the original BA158-TP.

Q: What is the significance of the operating temperature range difference?

A: BA158-TP is rated -65°C to 125°C, while BA158GP-TP and 1N4005-E3/54 extend to 150°C. The extended range provides additional thermal margin in high-temperature environments. BA158-E3/54 matches the original -65°C to 125°C range. For applications operating near the upper temperature limit, the extended-range substitutes offer design flexibility.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes, for through-hole mounting. All parts use DO-41 (DO-204AL) axial package with identical pin spacing and mechanical dimensions. PCB layout modifications are not required. Packaging format differences (tube, tape & reel, cut tape) affect only component handling and assembly processes, not circuit performance.

Q: What is the difference between BA158-E3/54 and 1N4005-E3/54?

A: Both are Vishay parts in DO-41 packages with 600 V, 1 A ratings. BA158-E3/54 features fast recovery (150 ns) and 1.3 V forward voltage, matching BA158-TP electrical performance. 1N4005-E3/54 features standard recovery and 1.1 V forward voltage. BA158-E3/54 is the closer electrical equivalent; 1N4005-E3/54 is suitable only when recovery speed is not critical.
