Engineering Selection Recommendations

Choose substitute parts based on product status, compliance information, and available certifications:

For applications requiring RoHS compliance, select 1N4582A (ROHS3 Compliant).
For through-hole mounting in DO-35 or DO-204AH packages, all listed substitutes meet the mechanical requirements.
Verify inventory status as provided to ensure supply continuity.
Note product status for JANTX1N4583A-1 is discontinued at Digi-Key.
For REACH compliance and ECCN/HTSUS classifications, all substitutes are unaffected and maintain consistency.

Frequently Asked Questions (FAQ)

Q1: What are the required parameters for equivalent Zener diode substitution?
A1: Substitute parts must match Zener voltage, tolerance, power rating, impedance, reverse leakage current, operating temperature range, mounting type, and package/case.

Q2: Are the substitute diodes mechanically interchangeable with 1N4582-1?
A2: All substitutes provided use a DO-35 (DO-204AH) through-hole axial package, maintaining mechanical interchangeability.

Q3: Does RoHS compliance impact substitute selection?
A3: Yes. 1N4582A is ROHS3 Compliant, whereas some other substitutes are RoHS non-compliant. Select based on the application's regulatory requirements.

Q4: Is qualification or grade information relevant for these substitutes?
A4: JANTX1N4583A-1 has a military grade and MIL-PRF-19500/452 qualification as provided in the input.

Q5: What is the significance of REACH, ECCN, and HTSUS codes in selection?
A5: These codes and statuses inform environmental and export classifications, with all substitutes having matching or unaffected designations as specified.

Q6: How does inventory influence component selection?
A6: Use available inventory data for production planning and supply chain continuity, as provided for each part.

Q7: What package types are supported for substitution?
A7: All listed equivalent and substitute Zener diodes use DO-204AH or DO-35 axial packages, suitable for through-hole applications.
