Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDLL5535C/TR are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic requires exact matching of the following parameters:

• Zener voltage (Vz): 15 V nominal
• Voltage tolerance: ±2%
• Maximum power dissipation: 500 mW
• Maximum impedance (Zzt): 100 Ohms
• Reverse leakage current: 10 nA @ 13.5 V
• Forward voltage: 1.1 V maximum @ 200 mA
• Operating temperature range: -65°C to 175°C
• Package type: DO-213AA surface mount
• Packaging format: Tape & Reel (TR)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. No deviations in electrical performance, thermal characteristics, or mechanical form factor are permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

Both the CDLL5535C/TR and 1N5535CUR-1/TR are active production components manufactured by Microchip Technology with identical electrical specifications and mechanical packaging. Selection between these parts is based on inventory availability and supply chain requirements rather than technical performance differences.

The CDLL5535C/TR maintains 688 units in new original stock, while the 1N5535CUR-1/TR provides 936 units in new original inventory. Both components carry identical export classification (EAR99) and harmonized tariff codes (8541.10.0050), ensuring equivalent compliance status for procurement and regulatory purposes.

The 1N5535CUR-1/TR includes documented Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. This specification is provided for the substitute part and supports extended shelf-life applications.

Frequently Asked Questions (FAQ)

Q: Can the 1N5535CUR-1/TR be used as a direct replacement for the CDLL5535C/TR?

A: Yes. Both parts are parametric equivalents with identical Zener voltage (15 V), tolerance (±2%), power rating (500 mW), impedance (100 Ohms), reverse leakage current (10 nA @ 13.5 V), forward voltage (1.1 V @ 200 mA), operating temperature range (-65°C to 175°C), and DO-213AA surface mount package. No circuit modifications or design changes are required.

Q: Are there any differences in the DO-213AA package between these parts?

A: No. Both components use the identical DO-213AA surface mount package with Tape & Reel (TR) packaging format. PCB footprints, solder pad dimensions, and pick-and-place specifications are equivalent.

Q: What is the significance of the MSL rating on the 1N5535CUR-1/TR?

A: The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates that the 1N5535CUR-1/TR has no moisture sensitivity constraints. This part can be stored and handled without time-limited exposure restrictions, supporting extended inventory management and supply chain flexibility.

Q: Are both parts manufactured by the same company?

A: Yes. Both the CDLL5535C/TR and 1N5535CUR-1/TR are manufactured by Microchip Technology, ensuring consistent quality standards, process controls, and technical support.
