Engineering Selection Recommendations

The RG 2 is obsolete. All listed substitutes (1N5395-E3/73, 1N5395GP-E3/54, GP15G-E3/54, RGP15G-E3/54) are currently active with RoHS compliance and matching or exceeding core electrical and mechanical specifications. Each substitute meets the necessary requirements for environmental responsibility and inventory availability.

Frequently Asked Questions (FAQ)

Q1: What are the required parameters for substituting the RG 2 diode?
A1: Substitution requires matching the voltage rating (400 V), rectified current (≥1.2A), mounting type (through hole, axial), package compatibility, operating temperature, and RoHS compliance.

Q2: Are package and mounting variations acceptable among substitutes?
A2: All substitutes utilize through-hole axial packages with standard DO-41 or DO-15 variations, which are compatible with standard axial mounting specifications.

Q3: Do the substitute parts provide equivalent or superior performance to RG 2?
A3: Substitute parts meet or exceed the critical ratings for voltage, current, and recovery characteristics as defined by the original RG 2 part parameters.

Q4: How is RoHS compliance verified among substitutes?
A4: Each listed substitute indicates ROHS3 Compliant status, in accordance with documented environmental standards.

Q5: Is there any consideration required for the product status of substitute parts?
A5: Only substitutes with active product status are included, ensuring current availability and ongoing manufacturer support.
