Substitute Part Grouping Explanation

Substitution of the SMBJ5364B/TR13 is determined by electrical and mechanical parameter equivalence. The primary substitution criteria are:

Zener Voltage (Vz): Must be 33 V nominal
Power Rating: Must be 5 W maximum
Tolerance: Must be ±5%
Impedance (Zzt): Must be 10 Ohms maximum
Reverse Leakage Current: Must be 500 nA at specified reverse voltage
Forward Voltage: Must be 1.2 V maximum at rated forward current
Package Type: Must be DO-214AA (SMB) Surface Mount
Mounting Configuration: Must be Surface Mount compatible with Tape & Reel delivery

The substitute part SMBJ5364B-TP, manufactured by Micro Commercial Co, meets all electrical specifications and package requirements. Differences in operating temperature range and RoHS compliance status do not affect functional substitution within the specified electrical parameters.

Engineering Selection Recommendations

SMBJ5364B/TR13 (Microchip Technology) is the primary part specification. This component is Active in product status with 1068 pieces available in inventory. The part is RoHS non-compliant and carries REACH Unaffected status.

SMBJ5364B-TP (Micro Commercial Co) is a direct electrical and mechanical equivalent. This substitute part is also Active in product status with significantly higher inventory availability (41,826 pieces). The key distinction is ROHS3 compliance, which makes this substitute suitable for applications requiring RoHS-compliant components. The operating temperature range is -55°C to 150°C compared to -65°C to 150°C for the primary part; this difference is compatible with most standard industrial and commercial applications.

Selection between these parts should be based on:

Compliance Requirements: If RoHS3 compliance is mandatory, select SMBJ5364B-TP
Temperature Range: If operation below -55°C is required, select SMBJ5364B/TR13
Inventory Availability: SMBJ5364B-TP offers substantially higher stock levels
Supply Chain Continuity: Either part provides equivalent electrical performance for direct substitution

Frequently Asked Questions (FAQ)

Q: Can SMBJ5364B-TP be used as a direct replacement for SMBJ5364B/TR13?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical Zener voltage (33 V), power rating (5 W), tolerance (±5%), impedance (10 Ohms maximum), and package type (DO-214AA SMB Surface Mount). The parts are interchangeable in circuit applications where the operating temperature range of -55°C to 150°C is acceptable.

Q: What is the difference in RoHS compliance between these parts?

A: SMBJ5364B/TR13 is RoHS non-compliant. SMBJ5364B-TP is ROHS3 compliant. If your application or end-market requires RoHS3 certification, SMBJ5364B-TP must be selected. Both parts carry REACH Unaffected status.

Q: Are there differences in operating temperature ranges?

A: Yes. SMBJ5364B/TR13 operates from -65°C to 150°C. SMBJ5364B-TP operates from -55°C to 150°C. The substitute part has a narrower lower temperature limit by 10°C. For applications requiring operation below -55°C, the primary part must be used.

Q: Do both parts use the same package and mounting method?

A: Yes. Both parts use DO-214AA (SMB) Surface Mount package. Both are supplied in Tape & Reel format. PCB footprints and assembly processes are identical.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution is determined by matching Zener voltage (33 V), power rating (5 W), tolerance (±5%), impedance (10 Ohms maximum), reverse leakage current (500 nA), forward voltage (1.2 V maximum), and package type (DO-214AA SMB). All these parameters are identical between the primary part and substitute.

Q: Which part should be selected for new designs?

A: Selection depends on compliance and temperature requirements. For RoHS3-compliant designs, use SMBJ5364B-TP. For applications requiring extended low-temperature operation below -55°C, use SMBJ5364B/TR13. Both parts are Active in product status and suitable for production use.
