S5BL-TP Equivalent & Substitute Parts

Part Overview

The S5BL-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 5 A average rectified current in a surface mount SMC (DO-214AB) package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary to maintain design continuity, support existing production lines, and ensure component availability for legacy systems.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S5BL-TP are identified based on electrical and mechanical parameter equivalence. The primary substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 5 A
• Recovery Speed: Standard Recovery >500ns, > 200mA (Io)
• Operating Temperature Range: -55°C to 150°C
• Current - Reverse Leakage @ Vr: 10 µA @ 100 V

Mechanical Parameters:

• Package / Case: DO-214AB, SMC (surface mount)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part S5B_R1_00001 meets all electrical and mechanical requirements for direct substitution. Minor variations in forward voltage (1.1 V vs. 1.2 V) and junction capacitance (80 pF vs. 100 pF) remain within acceptable tolerance ranges for general-purpose rectification applications and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

S5B_R1_00001 (Panjit International Inc.) is a direct substitute for the S5BL-TP. Selection of this substitute is supported by the following factors:

1. Electrical Equivalence: All critical electrical parameters—reverse voltage rating, average rectified current, recovery speed, reverse leakage current, and operating temperature range—are identical to the main part.

2. Mechanical Compatibility: Both parts use the DO-214AB SMC surface mount package, ensuring identical PCB footprint and assembly compatibility.

3. Compliance Alignment: The substitute part maintains ROHS3 compliance and MSL 1 rating, meeting the same regulatory and environmental requirements as the original component.

4. Active Product Status: Unlike the S5BL-TP (Not For New Designs), the S5B_R1_00001 maintains Active product status, ensuring continued availability and manufacturer support.

5. Minor Parameter Variations: The forward voltage reduction (1.1 V vs. 1.2 V) and junction capacitance reduction (80 pF vs. 100 pF) represent improvements in performance characteristics and do not introduce compatibility issues in standard rectification circuits.

Frequently Asked Questions (FAQ)

Q: Can S5B_R1_00001 be used as a direct replacement for S5BL-TP in existing designs?

A: Yes. The S5B_R1_00001 meets all electrical and mechanical specifications required for direct substitution. Both parts share identical voltage ratings, current ratings, package type, and operating temperature range.

Q: What is the difference in forward voltage between these parts?

A: The S5BL-TP has a maximum forward voltage of 1.2 V at 5 A, while the S5B_R1_00001 has a maximum forward voltage of 1.1 V at 5 A. This 0.1 V difference represents a minor improvement in the substitute part and does not affect circuit functionality in general-purpose rectification applications.

Q: Are the packages physically identical?

A: Yes. Both parts use the DO-214AB SMC surface mount package. PCB footprints, land patterns, and assembly processes are identical.

Q: Does the substitute part meet the same compliance standards?

A: Yes. The S5B_R1_00001 is ROHS3 compliant and carries MSL 1 (Unlimited) rating, matching the compliance profile of the S5BL-TP.

Q: Why is the S5BL-TP marked as "Not For New Designs"?

A: The S5BL-TP has reached end-of-life status. The S5B_R1_00001 maintains Active product status and is the recommended substitute for new designs and ongoing production support.

Q: What is the difference in junction capacitance?

A: The S5BL-TP has a junction capacitance of 100 pF at 4 V and 1 MHz, while the S5B_R1_00001 has 80 pF at the same conditions. This lower capacitance in the substitute part may provide marginal improvements in high-frequency switching applications but does not affect compatibility in standard rectification circuits.

Q: Are there any thermal considerations when substituting these parts?

A: No. Both parts share the same operating temperature range of -55°C to 150°C at the junction. Thermal management requirements and design considerations remain unchanged.
