B180B-13 Equivalent & Substitute Parts

Part Overview

The B180B-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, rated for 80V DC reverse voltage and 1A average rectified current in a Surface Mount SMB (DO-214AA) package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the specified parameter ranges. The B180B-13 has direct manufacturer variants and cross-manufacturer alternatives that satisfy the same functional requirements for rectification applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B180B-13 is determined by the following criteria:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): Must equal or exceed 80V
• Technology: Must be Schottky rectifier diode
• Package / Case: Must be DO-214AA or SMB compatible
• Mounting Type: Must be Surface Mount
• RoHS Status: Must maintain ROHS3 compliance
• Moisture Sensitivity Level: Must be MSL 1 or lower

Current Rating Consideration: Current - Average Rectified (Io) may exceed the 1A specification of the main part, as higher current ratings are backward compatible in rectifier applications where the circuit operates at or below the original current requirement.

Identified Substitute Parts:

1. B180B-13-F (Diodes Incorporated) — Direct manufacturer variant with identical electrical specifications and Tape & Reel packaging
2. SK38B-LTP (Micro Commercial Co) — Cross-manufacturer alternative with higher current rating (3A) and equivalent voltage/package specifications

Parameter Comparison

Engineering Selection Recommendations

B180B-13-F (Diodes Incorporated): This part is the preferred direct substitute. It maintains identical electrical specifications (80V, 1A) and is manufactured by the same supplier as the main part. Both parts are Active product status, ensuring continued availability and support. The B180B-13-F differs only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), making it suitable for high-volume production environments. RoHS3 compliance and MSL 1 rating are maintained.

SK38B-LTP (Micro Commercial Co): This part is a functional equivalent with higher current capacity (3A versus 1A). It satisfies all primary substitution criteria: 80V reverse voltage, Schottky technology, DO-214AA/SMB package, and Surface Mount configuration. However, the SK38B-LTP carries "Not For New Designs" product status, indicating the manufacturer has discontinued active development. This part is suitable only for legacy system maintenance or replacement applications where the original part is unavailable. The operating temperature range is narrower (-55°C to 150°C versus -65°C to 150°C for B180B-13-F).

Compliance Summary: All three parts maintain ROHS3 compliance, MSL 1 rating, and REACH Unaffected status, satisfying regulatory requirements for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can B180B-13-F be used as a direct replacement for B180B-13?

A: Yes. The B180B-13-F is a direct electrical and mechanical equivalent manufactured by Diodes Incorporated. The only difference is packaging format: B180B-13 is supplied in Cut Tape & Digi-Reel format, while B180B-13-F is supplied in Tape & Reel format. Both parts have identical voltage (80V), current (1A), and package specifications (DO-214AA, SMB).

Q: What is the difference between B180B-13 and SK38B-LTP?

A: Both parts share the same 80V reverse voltage rating and DO-214AA/SMB package. The primary difference is current rating: B180B-13 is rated for 1A average rectified current, while SK38B-LTP is rated for 3A. SK38B-LTP also has higher forward voltage (850mV @ 3A versus 790mV @ 1A) and higher capacitance (250pF versus 80pF). SK38B-LTP is manufactured by Micro Commercial Co and carries "Not For New Designs" status.

Q: Is SK38B-LTP suitable for new product designs?

A: No. SK38B-LTP carries "Not For New Designs" product status, indicating the manufacturer has discontinued active support. For new designs, use B180B-13 or B180B-13-F, both of which are Active status parts from Diodes Incorporated.

Q: Can SK38B-LTP be used in applications designed for B180B-13?

A: SK38B-LTP can be used in applications where the circuit operates at or below 1A, as the higher 3A rating is backward compatible. However, the higher forward voltage drop (850mV @ 3A versus 790mV @ 1A) and higher capacitance (250pF versus 80pF) may affect circuit performance in sensitive applications. The narrower operating temperature range (-55°C to 150°C versus -65°C to 150°C) must also be considered for extreme temperature environments.

Q: Are all three parts RoHS3 compliant?

A: Yes. B180B-13, B180B-13-F, and SK38B-LTP are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level and REACH Unaffected status.

Q: What packaging formats are available?

A: B180B-13 is supplied in Cut Tape (CT) & Digi-Reel format. B180B-13-F and SK38B-LTP are supplied in Tape & Reel (TR) format. All three parts use the same DO-214AA/SMB surface mount package.
