• Current - Average Rectified (Io): 1 A minimum
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: Must accommodate application requirements

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, or Axial configuration
• Supplier Device Package: Compatible with DO-41 footprint

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The MUR120RLG from onsemi meets all substitution criteria and is classified as an active product, making it suitable for new designs and ongoing supply applications.

Engineering Selection Recommendations

Primary Substitute: MUR120RLG

The MUR120RLG is the direct equivalent for the MUR120GP-TP and is the recommended substitute for all applications. Selection rationale:

1. Electrical Equivalence: Both parts share identical voltage and current ratings (200 V, 1 A) and fast recovery speed classification. The MUR120RLG exhibits superior performance characteristics with lower forward voltage drop (0.875 V vs. 1.35 V), faster reverse recovery time (35 ns vs. 45 ns), and lower reverse leakage current (2 µA vs. 5 µA).

2. Product Status: The MUR120RLG is classified as Active, ensuring continued availability and suitability for new designs. The MUR120GP-TP is marked "Not For New Designs," making the MUR120RLG the appropriate long-term solution.

3. Compliance Certification: Both parts are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for industrial and commercial applications.

4. Thermal Performance: The MUR120RLG supports an extended operating temperature range (-65°C to 175°C) compared to the MUR120GP-TP (-65°C to 150°C), providing additional margin for high-temperature applications.

5. Mechanical Compatibility: Both parts utilize identical through-hole DO-41 axial packaging, ensuring direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the MUR120RLG be used as a direct replacement for the MUR120GP-TP without PCB modifications?

A: Yes. Both parts share identical mechanical specifications: through-hole mounting, DO-41 axial package, and DO-204AL case designation. No PCB layout changes are required for substitution.

Q: What are the key electrical differences between these parts?

A: The MUR120RLG demonstrates improved electrical performance: forward voltage drop is reduced from 1.35 V to 0.875 V at 1 A, reverse recovery time is faster (35 ns vs. 45 ns), and reverse leakage current is lower (2 µA vs. 5 µA). Both parts maintain identical 200 V reverse voltage and 1 A current ratings.

Q: Why is the MUR120GP-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. The MUR120RLG, classified as Active, is the appropriate choice for ongoing and future applications.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both the MUR120GP-TP and MUR120RLG are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements for industrial and commercial use.

Q: Does the extended temperature range of the MUR120RLG affect substitution suitability?

A: The MUR120RLG's extended operating temperature range (-65°C to 175°C vs. -65°C to 150°C) provides additional thermal margin and does not restrict substitution. Applications operating within the original MUR120GP-TP temperature range remain fully compatible.

Q: What packaging formats are available for the MUR120RLG?

A: The MUR120RLG is supplied in Cut Tape (CT) packaging. The MUR120GP-TP was supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format selection depends on procurement and assembly requirements.
