Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMF207FRE1R5 is determined by the following critical parameters:

• Resistance value: 1.5 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity level: 1 (exact match required)

The MMA02040C1508FB300 qualifies as a substitute part because it maintains all critical electrical parameters and compliance certifications. While the package transitions from MELF 0207 to MELF 0204 and power rating decreases from 0.6W to 0.4W, these dimensional and power differences are within acceptable substitution parameters for applications where the 0.4W rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

Both the MMF207FRE1R5 and MMA02040C1508FB300 maintain identical electrical specifications for resistance, tolerance, temperature coefficient, and operating temperature range. Both components are ROHS3 compliant and carry MSL 1 rating, ensuring compatibility in standard manufacturing environments.

The MMA02040C1508FB300 includes AEC-Q200 automotive qualification and anti-sulfur features, providing additional reliability certifications. Selection between these parts should be based on:

• PCB layout constraints: The smaller MELF 0204 package of the substitute may require design verification for mechanical fit
• Power dissipation requirements: Applications requiring sustained power dissipation above 0.4W necessitate the main part (0.6W rating)
• Automotive qualification requirements: The substitute part's AEC-Q200 rating is beneficial for automotive applications

Frequently Asked Questions (FAQ)

Q: Can the MMA02040C1508FB300 replace the MMF207FRE1R5 in all applications?

A: Electrical substitution is valid for applications where power dissipation does not exceed 0.4W. PCB layout must accommodate the smaller MELF 0204 package dimensions (1.40mm x 3.60mm versus 2.20mm x 5.90mm).

Q: What is the difference between Metal Film and Thin Film composition?

A: Both compositions provide the specified ±1% tolerance and ±50ppm/°C temperature coefficient. Thin Film construction in the substitute part offers enhanced stability characteristics and is commonly used in precision applications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both components operate across the identical temperature range of -55°C to 155°C and maintain specified tolerance and temperature coefficient throughout this range.

Q: Does the substitute part require different handling or storage?

A: No. Both components carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity and storage requirements.

Q: Is the AEC-Q200 rating on the substitute part a requirement for my application?

A: AEC-Q200 qualification is required only for automotive applications. For non-automotive use, this certification provides additional assurance but is not mandatory.
