Substitute Part Grouping Explanation
Substitution of the BZX55C36-TAP is determined by equivalence across the following critical parameters:
Electrical Equivalence Criteria:
- Nominal Zener voltage: 36 V (fixed requirement)
- Maximum power dissipation: 500 mW (fixed requirement)
- Impedance (Max): 80 Ohms (fixed requirement)
- Reverse leakage current: 100 nA @ 27 V (fixed requirement)
- Forward voltage: 1.5 V @ 200 mA (fixed requirement)
- Operating temperature range: -65°C to 175°C (fixed requirement)
Mechanical Equivalence Criteria:
- Package type: DO-204AH (DO-35) axial through-hole (fixed requirement)
- Mounting type: Through-hole (fixed requirement)
Compliance Equivalence Criteria:
- Automotive grade classification (fixed requirement)
- AEC-Q101 qualification (fixed requirement)
- RoHS3 compliance (fixed requirement)
The BZX55B36-TAP qualifies as a parametric equivalent substitute. While the tolerance specification differs (±2% versus ±5%), all electrical performance parameters, mechanical packaging, and automotive compliance certifications remain identical. The tighter tolerance of the substitute part does not restrict its use in applications designed for the primary part.

Engineering Selection Recommendations
Both the BZX55C36-TAP and BZX55B36-TAP maintain Active product status and are manufactured by the same supplier. Both components carry AEC-Q101 automotive qualification and RoHS3 compliance certification, confirming suitability for automotive applications requiring regulatory adherence.
The BZX55B36-TAP substitute part provides identical electrical performance and mechanical compatibility. The tighter tolerance specification (±2% versus ±5%) represents an enhancement rather than a limitation, as it provides improved voltage regulation accuracy without compromising circuit design margins.
Selection between the main part and substitute should be based on inventory availability, lead time requirements, and cost considerations. Both parts are functionally interchangeable within the specified electrical and mechanical parameters.
Frequently Asked Questions (FAQ)
Q: Can the BZX55B36-TAP replace the BZX55C36-TAP in existing designs?
A: Yes. The BZX55B36-TAP is electrically and mechanically equivalent. All critical parameters including Zener voltage, power rating, impedance, leakage current, and forward voltage are identical. Both components share identical package specifications (DO-204AH/DO-35 axial through-hole) and automotive qualifications.
Q: What is the difference between the ±5% and ±2% tolerance specifications?
A: Tolerance defines the allowable deviation of the Zener voltage from the nominal 36 V specification. The BZX55C36-TAP allows ±5% deviation (34.2 V to 37.8 V), while the BZX55B36-TAP allows ±2% deviation (35.28 V to 36.72 V). The tighter tolerance of the substitute part provides more precise voltage regulation and does not restrict its use in applications designed for the primary part.
Q: Are both parts suitable for automotive applications?
A: Yes. Both the BZX55C36-TAP and BZX55B36-TAP carry Automotive grade classification and AEC-Q101 qualification, confirming compliance with automotive reliability and quality standards.
Q: Do the parts require different PCB footprints or mounting procedures?
A: No. Both components use identical DO-204AH (DO-35) axial through-hole packaging. PCB footprints, lead spacing, and mounting procedures are identical.
Q: What is the operating temperature range for both parts?
A: Both the BZX55C36-TAP and BZX55B36-TAP operate across the identical temperature range of -65°C to 175°C, ensuring consistent performance across automotive environmental conditions.
Q: Are both parts RoHS compliant?
A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.
