Engineering Selection Recommendations

The RM 11C is marked as obsolete. Substitute models 1N5399-E3/54, 1N5399-E3/73, GP15M-E3/54, and GP15M-E3/73 all have active product status, are RoHS compliant, and have an unlimited moisture sensitivity level (MSL 1). These substitute parts match or exceed all relevant electrical, mechanical, and regulatory parameters as provided.

Frequently Asked Questions (FAQ)

Q1: What key parameters ensure substitutability for the RM 11C diode in the Diodes, Rectifiers category?
A1: Compatibility is established by matching maximum reverse voltage (1000 V), average rectified current (≥ 1.2 A), recovery speed, through-hole axial mounting, and equivalent RoHS and MSL compliance.

Q2: Are the substitute parts compatible in terms of electrical performance?
A2: All substitute parts have equal or higher maximum reverse voltage and average rectified current. Forward voltage specifications and reverse leakage are similar or improved.

Q3: Do package differences affect interchangeability?
A3: All options use through-hole, axial packages and are suitable where original mounting requirements specify an axial component.

Q4: What regulatory or compliance considerations are addressed with these substitutes?
A4: Substitute parts are RoHS compliant and have identical moisture sensitivity levels (MSL 1), ensuring compatibility with regulated manufacturing environments.

Q5: Why must substitutes be used for RM 11C?
A5: RM 11C is classified as obsolete, and substitution is required to maintain production continuity for designs using this component.
