Substitute Part Grouping Explanation

Substitute parts for the CFSH-4 TR PBFREE are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 40V minimum
• Current - Average Rectified (Io): 200mA minimum
• Technology: Schottky diode
• Mounting Type: Surface Mount
• Package compatibility: SOD-882 or equivalent footprint
• RoHS3 Compliance: Required
• Operating Temperature Range: Must support -65°C to 125°C junction temperature or higher

Secondary Compatibility Parameters:

• Forward voltage characteristics within acceptable application range
• Reverse leakage current specifications
• Reverse recovery time performance
• Capacitance ratings at specified bias conditions

The PMEG4002EL,315 from Nexperia USA Inc. meets all primary substitution criteria and is classified as a direct substitute for the CFSH-4 TR PBFREE.

Engineering Selection Recommendations

PMEG4002EL,315 as Substitute for CFSH-4 TR PBFREE:

The PMEG4002EL,315 qualifies as a direct substitute based on matched voltage and current ratings, identical Schottky technology, and equivalent surface mount SOD-882 packaging. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring equivalent handling and storage requirements.

The substitute part demonstrates improved forward voltage characteristics (600 mV @ 200 mA versus 1 V @ 40 mA), which represents a performance advantage in applications sensitive to power dissipation. The higher maximum junction temperature rating (150°C versus 125°C) provides additional thermal margin in demanding environments.

Reverse leakage current is higher in the substitute (10 µA @ 40 V versus 200 nA @ 30 V), which may be relevant in high-impedance or precision analog applications. Capacitance is also higher (20 pF @ 1V, 1MHz versus 5 pF @ 0V, 1MHz), which may affect high-frequency switching performance.

Both components maintain active product status and are available in production quantities, supporting long-term supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can PMEG4002EL,315 be used as a direct replacement for CFSH-4 TR PBFREE in all applications?

A: PMEG4002EL,315 meets all primary electrical and mechanical substitution criteria: 40V reverse voltage rating, 200mA current rating, Schottky technology, and SOD-882 surface mount package. However, application-specific factors such as forward voltage drop, reverse leakage current, and capacitance characteristics must be evaluated within the context of the target circuit design.

Q: What are the key differences between these two parts?

A: The primary differences are forward voltage (PMEG4002EL,315 is lower at 600 mV @ 200 mA), reverse leakage current (PMEG4002EL,315 is higher at 10 µA @ 40 V), capacitance (PMEG4002EL,315 is higher at 20 pF @ 1V, 1MHz), and maximum junction temperature (PMEG4002EL,315 supports 150°C versus 125°C). Both parts share identical voltage and current ratings and package specifications.

Q: Are the packages physically identical?

A: Both components use the SOD-882 surface mount package. The CFSH-4 TR PBFREE is supplied in Tape & Reel (TR) format, while PMEG4002EL,315 is supplied in Cut Tape (CT) & Digi-Reel® format. The physical package footprint and land pattern are equivalent, supporting direct PCB layout compatibility.

Q: Do both parts have the same compliance certifications?

A: Yes. Both CFSH-4 TR PBFREE and PMEG4002EL,315 are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Both are classified as MSL 1 (Unlimited) for moisture sensitivity, indicating equivalent handling and storage requirements.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. PMEG4002EL,315 offers lower forward voltage drop and higher temperature rating, making it suitable for power-sensitive or thermally demanding applications. CFSH-4 TR PBFREE may be preferred where lower reverse leakage current or lower capacitance is critical. Both parts are active and available in production quantities.
