Parameter Comparison

Engineering Selection Recommendations

The MMA02040C1330FB300 is a qualified substitute for the SMM02040C1330FB300 in applications where the following conditions are met:

Direct Substitution Conditions:

• Circuit design requires 133 Ohm resistance with ±1% tolerance
• MELF 0204 package footprint is specified
• Automotive AEC-Q200 qualification is required
• Operating temperature does not exceed 125°C (main part specification)
• Anti-sulfur coating requirement is mandatory

Enhanced Performance Conditions:

• Applications operating at temperatures between 125°C and 155°C benefit from the extended operating range of the MMA02040C1330FB300
• Circuits with higher power dissipation margins benefit from the 0.4W rating versus 0.25W
• Both parts maintain identical electrical performance and compliance certifications

Packaging Considerations:

• The MMA02040C1330FB300 is supplied in Cut Tape (CT) & Digi-Reel® format, whereas the SMM02040C1330FB300 uses standard Tape & Reel (TR)
• Both packaging formats are suitable for automated assembly processes
• Inventory availability: MMA02040C1330FB300 has 9162 units in stock versus 3020 units for SMM02040C1330FB300

Frequently Asked Questions (FAQ)

Q: Can the MMA02040C1330FB300 replace the SMM02040C1330FB300 in all applications?

A: Yes, the MMA02040C1330FB300 is a direct electrical and mechanical substitute. Both parts share identical resistance, tolerance, temperature coefficient, package dimensions, and AEC-Q200 automotive qualification. The substitute offers enhanced specifications (higher power rating and extended temperature range) that do not create compatibility issues in circuits designed for the original part.

Q: What is the difference in power rating between these parts?

A: The SMM02040C1330FB300 is rated at 0.25W (1/4W), while the MMA02040C1330FB300 is rated at 0.4W (2/5W). Both parts are housed in the identical MELF 0204 package. The higher power rating of the substitute provides additional thermal margin in applications with higher power dissipation requirements.

Q: Are there temperature range differences?

A: The SMM02040C1330FB300 operates from -55°C to 125°C, while the MMA02040C1330FB300 extends to 155°C. For applications operating within the -55°C to 125°C range, both parts perform identically. Applications requiring operation above 125°C must use the MMA02040C1330FB300.

Q: Do both parts meet automotive standards?

A: Yes, both the SMM02040C1330FB300 and MMA02040C1330FB300 carry AEC-Q200 automotive qualification, anti-sulfur coating, and ROHS3 compliance. Both are suitable for automotive applications requiring these certifications.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) is standard continuous reel packaging for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides flexible packaging options for lower-volume orders or mixed component requirements. Both formats are compatible with standard pick-and-place assembly equipment. The choice depends on procurement volume and assembly line requirements.

Q: Are the physical dimensions identical?

A: Yes, both parts have identical MELF 0204 package dimensions: 0.055" diameter × 0.142" length (1.40mm × 3.60mm). PCB footprints and assembly processes are interchangeable.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
