Engineering Selection Recommendations

Both BZT52C13 and BZT52C13 RHG are listed as Active products, ROHS3 Compliant, and REACH Unaffected. Both share the same manufacturer and identical electrical, thermal, and package characteristics. Either part satisfies substitution selection when compliance and environmental certifications are required.

Frequently Asked Questions (FAQ)

Q1: What criteria determine if a Zener diode is a valid drop-in substitute?
A1: Matching Zener voltage, tolerance, power rating, impedance, reverse leakage current, forward voltage, operating temperature range, mounting style, and package are essential for a valid substitute.

Q2: Does the BZT52C13 RHG have the same electrical and package characteristics as BZT52C13?
A2: Yes. Both parts have identical Zener voltage, tolerance, power rating, impedance, reverse leakage, forward voltage, operating temperature range, and SOD-123F package.

Q3: Are there differences in RoHS or REACH compliance status between BZT52C13 and BZT52C13 RHG?
A3: No. Both parts are listed as ROHS3 Compliant and REACH Unaffected.

Q4: Is there a need to evaluate the footprint or requalify the part in the same board design?
A4: No. Both use the SOD-123F package, indicating equivalent mechanical footprint and mounting method.

Q5: Are there differences in moisture sensitivity or product status?
A5: No differences. Both parts are listed as Moisture Sensitivity Level 1 (when specified) and are currently Active.
