Equivalent & Substitute Parts for CD0603-Z13

Part Overview

The CD0603-Z13 is a Zener diode rated at 13 V nominal voltage with 150 mW maximum power dissipation in a 0603 surface mount package. Manufactured by Bourns Inc., this component is classified as obsolete. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD0603-Z13 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Voltage - Zener (Nom) (Vz): 13 V
• Tolerance: ±5%
• Power - Max: 150 mW
• Impedance (Max) (Zzt): 25 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 10 V
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount
• Package / Case: 0603 (1608 Metric) / 2-SMD, No Lead

All substitute parts listed below meet these electrical specifications identically. The substitute parts are manufactured by Comchip Technology and maintain active product status, ensuring long-term availability and supply chain reliability compared to the obsolete Bourns original.

Parameter Comparison

Engineering Selection Recommendations

All four Comchip Technology substitute parts (CZRU52C13, CZRU52C13-HF, CZRUR52C13, CZRUR52C13-HF) are direct electrical and mechanical equivalents to the CD0603-Z13. Selection among these substitutes should be based on the following factors:

Product Status: All substitute parts maintain active product status, ensuring continued availability and manufacturing support. The CD0603-Z13 is obsolete and should be replaced in new designs and ongoing production.

Compliance Certifications: All substitute parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications as the original part.

Packaging and Supply: Substitute parts are supplied in Tape & Reel (TR) packaging format. Current inventory levels for active substitutes range from 671 to 2210 pieces, providing reliable supply chain access.

Thermal and Environmental Performance: All substitutes operate across the identical temperature range (-55°C ~ 125°C) and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent reliability in production and field applications.

Frequently Asked Questions (FAQ)

Q: Can CZRU52C13 directly replace CD0603-Z13 in existing designs?

A: Yes. The CZRU52C13 meets all electrical specifications (13 V nominal, 150 mW, ±5% tolerance, 25 Ohms impedance, 100 nA reverse leakage) and operates across the same temperature range. Both components use 0603 surface mount packaging with identical footprints.

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

A: Both parts are electrically identical with matching voltage, power, tolerance, and impedance specifications. The "-HF" designation indicates a halogen-free variant. Selection between these should be based on specific manufacturing or environmental requirements for halogen-free materials.

Q: Are CZRUR52C13 and CZRUR52C13-HF equivalent to CZRU52C13?

A: Yes. All four Comchip substitutes (CZRU52C13, CZRU52C13-HF, CZRUR52C13, CZRUR52C13-HF) are electrically and mechanically equivalent. The CZRUR designation represents an alternative product line variant within Comchip's portfolio, but specifications remain identical.

Q: Will the substitute parts fit the existing PCB layout designed for CD0603-Z13?

A: Yes. All substitute parts use 0603 surface mount packaging (2-SMD, No Lead / SOD-523F), which maintains the same footprint and land pattern as the original CD0603-Z13. No PCB redesign is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four Comchip substitute parts carry ROHS3 compliance certification, matching the compliance status of the original CD0603-Z13.

Q: What is the current inventory status for substitute parts?

A: CZRU52C13 has 2210 pieces in stock, CZRU52C13-HF has 671 pieces, CZRUR52C13 has 1000 pieces, and CZRUR52C13-HF has 825 pieces. All parts are new original stock from active manufacturers.
