Packaging Variation Allowance: Substitute parts may differ in packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) while maintaining identical electrical performance and mechanical compatibility. The supplier device package designation may vary (0603/SOD-523F vs. 0603C/SOD-523F) without affecting functional equivalence.

Compliance Consistency: All substitute parts maintain RoHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

CDBU0240 is a parametric equivalent available in Cut Tape and Digi-Reel® packaging formats. All electrical characteristics, thermal ratings, and compliance certifications are identical to the CDBUR0240. This part is suitable for applications where alternative packaging formats are acceptable. Product status is Active with high inventory availability (41,300 pcs).

CDBU0240-HF is a parametric equivalent available in Tape & Reel packaging. All electrical characteristics, thermal ratings, and compliance certifications are identical to the CDBUR0240. This part maintains the same packaging format as the main part number. Product status is Active with moderate inventory availability (2,400 pcs).

Both substitute parts maintain full compatibility with the CDBUR0240 in terms of electrical performance, mechanical fit, and regulatory compliance. Selection between alternatives should be based on packaging format requirements and inventory availability for procurement planning.

Frequently Asked Questions (FAQ)

Q: Can CDBU0240 be used as a direct replacement for CDBUR0240?

A: Yes. CDBU0240 is a parametric equivalent with identical electrical specifications (40 V reverse voltage, 200 mA average rectified current, 550 mV forward voltage at 200 mA, 10 µA reverse leakage, 9 pF capacitance). The primary difference is packaging format: CDBU0240 is supplied in Cut Tape and Digi-Reel® format, while CDBUR0240 is supplied in Tape & Reel format. Both use the same 2-SMD, No Lead package configuration and are mechanically compatible.

Q: What is the difference between CDBU0240 and CDBU0240-HF?

A: Both parts are parametric equivalents with identical electrical specifications. The difference is packaging format: CDBU0240 is available in Cut Tape and Digi-Reel® format, while CDBU0240-HF is supplied in Tape & Reel format. Electrical performance and mechanical compatibility are identical.

Q: Are all three parts (CDBUR0240, CDBU0240, CDBU0240-HF) interchangeable on a PCB?

A: Yes. All three parts use the same 2-SMD, No Lead package configuration (0603/SOD-523F or 0603C/SOD-523F) and are mechanically compatible for surface mount assembly. Electrical performance is identical across all three part numbers.

Q: Do these substitute parts meet the same compliance requirements?

A: Yes. All three parts are RoHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is consistent across all substitute options.

Q: Which substitute part should I select for new designs?

A: Selection should be based on packaging format availability and procurement requirements. CDBU0240-HF maintains the same Tape & Reel packaging as CDBUR0240. CDBU0240 offers an alternative in Cut Tape and Digi-Reel® format. All three parts are Active in product status and suitable for new designs.

Q: Is there a performance difference between the 0603/SOD-523F and 0603C/SOD-523F package designations?

A: No. Both package designations refer to the same 2-SMD, No Lead surface mount configuration with identical electrical and mechanical properties. The designations represent supplier package variations without functional impact.
