Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA158GP-TP are identified based on strict equivalence of the following electrical and mechanical parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Package / Case: DO-204AL, DO-41, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -65°C to 150°C
• RoHS Status: ROHS3 Compliant

The FR105T/R manufactured by EIC SEMICONDUCTOR INC. meets all critical substitution criteria for the BA158GP-TP in general-purpose rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

Both the BA158GP-TP and FR105T/R are Active product status components with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts is based on availability and supply chain requirements rather than electrical performance differences.

The BA158GP-TP features a reverse recovery time of 150 ns, while the FR105T/R has a reverse recovery time of 250 ns. Both values remain within the Fast Recovery classification (≤ 500ns, > 200mA). The capacitance specification differs (15 pF versus 50 pF at 4V, 1MHz), but both values are within acceptable ranges for general-purpose rectifier applications at the specified voltage and current ratings.

All other electrical parameters, mechanical specifications, and compliance certifications are identical between the two parts. Direct substitution is supported in circuit designs where the BA158GP-TP is specified.

Frequently Asked Questions (FAQ)

Q: Can the FR105T/R replace the BA158GP-TP in existing designs?

A: Yes. The FR105T/R meets all critical electrical and mechanical parameters for the BA158GP-TP, including voltage rating (600 V), current rating (1 A), forward voltage drop (1.3 V @ 1 A), fast recovery speed classification, DO-41 package, and operating temperature range (-65°C to 150°C). Both components are ROHS3 compliant and have identical moisture sensitivity levels.

Q: What are the differences between these two diodes?

A: The primary differences are reverse recovery time (150 ns for BA158GP-TP versus 250 ns for FR105T/R) and capacitance (15 pF versus 50 pF at 4V, 1MHz). Both values remain within acceptable specifications for general-purpose rectifier applications. These differences do not affect substitution compatibility for standard circuit applications.

Q: Are the packages identical?

A: Yes. Both the BA158GP-TP and FR105T/R use the DO-204AL, DO-41 axial through-hole package. Pin configuration and mechanical dimensions are identical, allowing direct board-level substitution without layout modifications.

Q: Do both parts have the same compliance certifications?

A: Yes. Both components are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited). Compliance status is equivalent for both parts.

Q: Which part should be selected for new designs?

A: Selection is based on availability and supply chain considerations. Both parts are Active status and provide equivalent performance for general-purpose 600 V, 1 A rectifier applications. Inventory levels and lead times should guide the selection decision.
