Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for axial metal film resistors is determined by the following criteria:

• Resistance value must match exactly: 35.7 Ohms
• Tolerance must be equal or tighter: ±1%
• Power rating must be equal or greater than the original specification
• Composition must remain metal film
• Package configuration must be axial
• Operating temperature range must encompass or match the original range
• RoHS and automotive compliance status must be maintained

The substitute part SFR16S0003579FR500 meets these criteria with a higher power rating (0.5W versus 0.4W), which provides additional thermal margin while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The SFR16S0003579FR500 is a valid substitute for the MBA02040C3579FRP00 based on the following factors:

Both parts are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain ROHS3 compliance. The substitute part carries a higher power rating (0.5W), which is acceptable for applications originally specified for 0.4W operation. The identical resistance value, tolerance, composition, and operating temperature range ensure functional equivalence in circuit applications.

The temperature coefficient of the substitute part is ±100ppm/°C compared to ±50ppm/°C for the original. This difference should be evaluated based on circuit-level temperature stability requirements. The packaging format differs (Cut Tape versus Tape & Reel), which affects procurement and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can SFR16S0003579FR500 be used as a direct replacement for MBA02040C3579FRP00?

A: Yes, the SFR16S0003579FR500 is electrically and mechanically compatible. Both parts share identical resistance, tolerance, composition, and operating temperature specifications. The substitute has a higher power rating, which provides additional thermal capacity without affecting circuit function.

Q: What is the difference in temperature coefficient between these parts?

A: The MBA02040C3579FRP00 has a temperature coefficient of ±50ppm/°C, while the SFR16S0003579FR500 has ±100ppm/°C. For applications requiring tight temperature stability, the original part specification should be verified against circuit requirements.

Q: Are there packaging considerations when substituting these parts?

A: The original part is supplied in Tape & Reel format, while the substitute is supplied in Cut Tape format. This affects procurement and automated assembly processes but does not impact the electrical or mechanical performance of the component itself.

Q: Do both parts meet automotive qualification standards?

A: The MBA02040C3579FRP00 carries AEC-Q200 automotive qualification. The SFR16S0003579FR500 does not list automotive qualification in the provided specifications. Automotive applications should verify compliance requirements before substitution.

Q: What is the physical size difference between these resistors?

A: The MBA02040C3579FRP00 measures 0.063" diameter × 0.142" length (1.60mm × 3.60mm). The SFR16S0003579FR500 measures 0.075" diameter × 0.138" length (1.90mm × 4.60mm). Both are axial configuration, but the slightly larger diameter of the substitute should be verified for board layout compatibility.
