MBR130LSF-TP Equivalent & Substitute Parts

Part Overview

The MBR130LSF-TP is a Schottky rectifier diode manufactured by Micro Commercial Co, rated for 30 V DC reverse voltage and 1 A average rectified current in a surface mount SOD-123FL package. This component is classified as Obsolete, necessitating identification of equivalent substitute parts for ongoing production and maintenance applications. The obsolete status requires engineers to evaluate functionally compatible alternatives that meet the electrical and mechanical requirements of the original design.

Substitute Part Grouping Explanation

Substitution of the MBR130LSF-TP is determined by the following electrical and mechanical criteria:

Mandatory Compatibility Parameters:

Technology: Schottky rectifier diode
Mounting Type: Surface Mount
Package / Case: SOD-123F
Current Rating: 1 A average rectified current minimum
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
RoHS Compliance: ROHS3 Compliant

Voltage Rating Consideration: The MBR130LSF-TP operates at 30 V maximum reverse voltage. Substitute parts with equal or higher voltage ratings are electrically compatible, as they can safely operate within the 30 V application requirement. Forward voltage characteristics must remain within acceptable circuit operating margins.

The SL14PL-TP meets all mandatory compatibility parameters with a 40 V reverse voltage rating, providing voltage margin above the original 30 V specification.

Engineering Selection Recommendations

The SL14PL-TP is electrically and mechanically compatible with the MBR130LSF-TP for direct substitution in applications requiring 30 V reverse voltage operation at 1 A current.

Compliance Considerations: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring no additional handling or storage requirements during transition.

Product Status Impact: The MBR130LSF-TP is classified as Obsolete, while the SL14PL-TP is classified as Not For New Designs. Both designations indicate restricted availability and limited manufacturer support. For new designs, consultation with the component manufacturer regarding current production alternatives is necessary.

Electrical Margin: The SL14PL-TP provides 10 V additional reverse voltage margin (40 V vs. 30 V) and an extended operating temperature range (-55°C to 150°C vs. -65°C to 125°C). The forward voltage increase of 20 mV at 1 A is within typical circuit tolerance for most rectification applications.

Frequently Asked Questions (FAQ)

Q: Can the SL14PL-TP directly replace the MBR130LSF-TP in existing designs?

A: Yes. Both components are Schottky rectifier diodes with identical 1 A current ratings, fast recovery speed characteristics, and SOD-123F surface mount packages. The SL14PL-TP's higher 40 V reverse voltage rating is compatible with 30 V application requirements.

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

A: The SL14PL-TP exhibits 400 mV forward voltage at 1 A compared to 380 mV for the MBR130LSF-TP. This 20 mV difference represents approximately 5% variation and is typical between different Schottky diode designs. Circuit designs with adequate voltage margin accommodate this difference without performance degradation.

Q: Are there packaging differences between these parts?

A: Both parts use the SOD-123F package for surface mount assembly. The MBR130LSF-TP is supplied in standard packaging, while the SL14PL-TP is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and does not affect component electrical characteristics or PCB assembly compatibility.

Q: What does the "Not For New Designs" status mean for the SL14PL-TP?

A: This designation indicates the manufacturer does not recommend this part for new product development. However, it remains available for existing production and maintenance applications. For new designs, contact the manufacturer to identify current production alternatives.

Q: How do the operating temperature ranges compare?

A: The MBR130LSF-TP operates from -65°C to 125°C junction temperature, while the SL14PL-TP operates from -55°C to 150°C. The SL14PL-TP provides a wider upper temperature margin of 25°C. Applications operating near the upper limit of the MBR130LSF-TP specification benefit from this extended range.

Q: Are both parts RoHS compliant?

A: Yes. Both the MBR130LSF-TP and SL14PL-TP are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring compatibility with current manufacturing and environmental standards.
