SL14PL-TP Equivalent & Substitute Parts

Part Overview

The SL14PL-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 40 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123FL package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identification of equivalent and substitute parts is necessary for applications requiring continued support, legacy system maintenance, or design transitions to active product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SL14PL-TP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 40 V
• Current - Average Rectified (Io) must equal or exceed 1 A
• Forward voltage (Vf) must be compatible with circuit design tolerances
• Reverse leakage current must not exceed application limits
• Speed classification must maintain Fast Recovery characteristics

Mechanical Compatibility Criteria:

• Package type must be SOD-123F (surface mount)
• Mounting type must be Surface Mount
• Operating temperature range must encompass application requirements

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The MBR130LSFT1G from onsemi meets the mechanical and compliance requirements but operates at a reduced voltage rating of 30 V, making it suitable only for applications where the circuit voltage does not exceed 30 V.

Parameter Comparison

Engineering Selection Recommendations

For applications operating at voltages ≤30 V: The MBR130LSFT1G is a direct functional substitute. This part is in active production status, ensuring long-term availability and supply chain stability. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, indicating equivalent handling and storage requirements. The substitute exhibits a lower forward voltage drop (380 mV versus 400 mV), which may provide marginal efficiency improvements in rectification circuits.

For applications operating at voltages between 30 V and 40 V: The MBR130LSFT1G cannot be used due to insufficient reverse voltage rating. The original SL14PL-TP must be retained or an alternative 40 V rated Schottky diode in SOD-123F package must be sourced from other manufacturers.

For applications requiring junction temperatures above 125°C: The MBR130LSFT1G has a maximum junction temperature of 125°C, compared to 150°C for the SL14PL-TP. Applications requiring operation above 125°C must use the original part or identify alternatives with equivalent thermal ratings.

Product Status Consideration: The SL14PL-TP is designated "Not For New Designs." For new product development, the MBR130LSFT1G (active status) is the preferred choice when voltage requirements do not exceed 30 V.

Frequently Asked Questions (FAQ)

Q: Can the MBR130LSFT1G replace the SL14PL-TP in all applications?

A: No. The MBR130LSFT1G has a maximum reverse voltage rating of 30 V, compared to 40 V for the SL14PL-TP. Substitution is valid only for circuits where the applied reverse voltage does not exceed 30 V. Applications requiring the full 40 V rating must use the original part or source an alternative 40 V rated Schottky diode.

Q: Are the packages physically identical?

A: Yes. Both the SL14PL-TP and MBR130LSFT1G use the SOD-123F surface mount package. PCB footprints and reflow soldering profiles are compatible.

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

A: The SL14PL-TP has a maximum forward voltage of 400 mV at 1 A, while the MBR130LSFT1G is rated at 380 mV at 1 A. The 20 mV difference is within typical manufacturing tolerances and may not be significant in most applications. Circuit design should account for the specified maximum values rather than typical values.

Q: Are there compliance or handling differences?

A: No. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings. Handling, storage, and compliance documentation requirements are equivalent.

Q: What is the reverse leakage current difference?

A: The SL14PL-TP specifies 500 µA at 40 V, while the MBR130LSFT1G specifies 1 mA at 30 V. Direct comparison is not valid because the measurements are taken at different voltages. At the MBR130LSFT1G's rated voltage of 30 V, its leakage current would be lower than 1 mA.

Q: Can I use the MBR130LSFT1G in a 40 V circuit?

A: No. Operating the MBR130LSFT1G at voltages exceeding its 30 V reverse voltage rating will cause device failure or degradation. The part must not be used in circuits where the reverse voltage may reach or exceed 30 V.

Q: Why is the SL14PL-TP marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory may remain available, but long-term supply cannot be guaranteed. New designs should transition to active products such as the MBR130LSFT1G where specifications permit.

Q: What is the maximum junction temperature difference?

A: The SL14PL-TP operates to 150°C junction temperature, while the MBR130LSFT1G is rated to 125°C. For applications requiring operation above 125°C, the original part must be used or an alternative with equivalent thermal rating must be identified.
