CZRU52C13 Equivalent & Substitute Parts

Part Overview

The CZRU52C13 is a Zener diode rated at 13 V nominal voltage with 150 mW maximum power dissipation in a 0603/SOD-523F surface mount package. Manufactured by Comchip Technology, this component is classified as Active and fully compliant with RoHS3 and REACH regulations. The part is supplied in Tape & Reel packaging with 2210 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in circuit applications. Substitution becomes necessary due to inventory availability, lead time constraints, or specific tolerance requirements for precision applications.

Substitute Part Grouping Explanation

Substitute parts for the CZRU52C13 are qualified based on the following critical parameters that determine functional equivalence:

Primary Equivalence Criteria:

• Zener voltage (Nom): 13 V
• Maximum power dissipation: 150 mW
• Package type: 0603/SOD-523F surface mount
• Impedance (Max): 25 Ohms
• Reverse leakage current: 100 nA
• Forward voltage: 900 mV @ 10 mA
• Operating temperature range: -55°C to 125°C
• Mounting type: Surface Mount
• Compliance: RoHS3, REACH Unaffected

Tolerance Variation: The CZRU52C13 operates at ±5% tolerance. Substitute CZRU13VB-HF offers tighter ±2% tolerance while maintaining all other electrical and mechanical parameters. CZRU52C13-HF maintains identical ±5% tolerance specification.

All substitute parts are manufactured by Comchip Technology, classified as Active products, and supplied in Tape & Reel packaging. Substitution is valid when circuit design permits the specified tolerance range.

Parameter Comparison

Engineering Selection Recommendations

CZRU52C13 (Primary Part) Select this part when standard ±5% tolerance meets circuit requirements and maximum inventory availability is preferred. All regulatory compliance certifications are current. Product status is Active with established supply chain.

CZRU13VB-HF (Precision Tolerance Substitute) Select this part when circuit design requires tighter ±2% tolerance specification for Zener voltage regulation. All electrical parameters remain equivalent to the primary part. RoHS3 and REACH compliance are maintained. Inventory availability is lower at 707 units.

CZRU52C13-HF (Identical Tolerance Substitute) Select this part as a direct functional equivalent when the primary CZRU52C13 is unavailable. Tolerance specification, electrical parameters, and compliance certifications are identical. Inventory availability is 671 units.

All three parts are qualified for applications requiring 13 V Zener regulation at 150 mW power dissipation in surface mount 0603/SOD-523F package format. Selection between CZRU52C13 and CZRU52C13-HF depends solely on inventory and lead time considerations, as electrical and mechanical specifications are identical.

Frequently Asked Questions (FAQ)

Q: Can CZRU13VB-HF replace CZRU52C13 in all applications?

A: CZRU13VB-HF is electrically and mechanically equivalent to CZRU52C13 with one difference: tighter ±2% tolerance versus ±5%. Substitution is valid when the circuit design permits or benefits from improved tolerance. If the original design specifically requires ±5% tolerance, verify that ±2% tolerance does not create over-specification or cost concerns.

Q: What is the difference between CZRU52C13 and CZRU52C13-HF?

A: These parts are functionally identical. Both feature 13 V nominal Zener voltage, 150 mW power rating, ±5% tolerance, 0603/SOD-523F package, and identical electrical parameters. Selection is based on inventory availability and supplier lead times only.

Q: Are all substitute parts in the same physical package?

A: Yes. CZRU52C13, CZRU13VB-HF, and CZRU52C13-HF all use the 0603/SOD-523F surface mount package with 2-SMD, No Lead configuration. Direct PCB footprint compatibility is confirmed.

Q: Do substitute parts meet the same regulatory requirements?

A: Yes. All three parts are RoHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent across all substitute options.

Q: What reverse leakage current specification applies to CZRU13VB-HF?

A: CZRU13VB-HF specifies 100 nA reverse leakage current at 9.9 V, compared to 100 nA @ 10 V for CZRU52C13 and CZRU52C13-HF. This represents a negligible difference in practical circuit operation and does not affect substitution validity.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts share identical mechanical dimensions, footprint requirements, and mounting specifications. PCB design and assembly processes require no modification when substituting between CZRU52C13, CZRU13VB-HF, and CZRU52C13-HF.
