Engineering Selection Recommendations

Substitute selection may be based on the following attributes:

Product status: All parts are active.
RoHS status: SMBJ5369A/TR13 is RoHS non-compliant. Substitute parts 1SMB5942BT3G and SZ1SMB5942BT3G are ROHS3 compliant.
REACH status, Moisture Sensitivity Level, ECCN, and HTSUS codes are consistent across all options.

Compliance status and active product designation are the main differentiators provided for engineering selection purposes.

Frequently Asked Questions (FAQ)

Q1: What are the critical substitution criteria for SMBJ5369A/TR13 zener diodes?
Substitution requires matching the zener voltage, mounting type, package/case, and operating temperature. Certification status and product status also apply.

Q2: Are the substitute diodes compatible with the same footprint as SMBJ5369A/TR13?
All listed substitutes use the DO-214AA, SMB surface mount package, which maintains mechanical compatibility.

Q3: Does the difference in power rating or zener tolerance affect eligibility for substitution?
Only parameters explicitly provided are compared. Tolerance and power ratings differ and must be considered as per input values.

Q4: How do RoHS and REACH compliance impact selection?
SMBJ5369A/TR13 is RoHS non-compliant; substitutes 1SMB5942BT3G and SZ1SMB5942BT3G are ROHS3 compliant. All are REACH unaffected, which may affect selection according to compliance requirements.

Q5: What should be checked regarding moisture sensitivity and operating temperature?
All parts are rated MSL 1 (unlimited) and have an operating temperature range of -65°C ~ 150°C per the provided data.

Q6: Are substitute parts from the same or different manufacturers?
SMBJ5369A/TR13 is from Microchip Technology; substitutes are from onsemi, all within the same zener diode category and mechanical package per input data.
