Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MBA02040C3240FRP00 is determined by the following critical parameters:

• Resistance value: Must be 324 Ohms
• Tolerance: Must be ±1% or tighter
• Composition: Must be metal film
• Package: Must be axial through-hole
• Operating temperature range: Must support -55°C ~ 155°C minimum
• Compliance: Must maintain ROHS3 and REACH compliance

The substitute part SFR16S0003240FR500 meets all core electrical and mechanical requirements. While it features a higher power rating (0.5W versus 0.4W) and a slightly different temperature coefficient (±100ppm/°C versus ±50ppm/°C), these parameters remain within acceptable substitution boundaries for most circuit applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain active product status and full compliance with ROHS3 and REACH regulations. The MBA02040C3240FRP00 is the primary specification with automotive AEC-Q200 qualification. The SFR16S0003240FR500 provides equivalent electrical performance with increased power dissipation capability. Selection between these parts should be based on circuit power requirements and thermal management considerations. The higher temperature coefficient of the substitute part (±100ppm/°C) may introduce slightly greater resistance drift across temperature extremes compared to the primary part (±50ppm/°C), which should be evaluated for precision-critical applications.

Frequently Asked Questions (FAQ)

Q: Can SFR16S0003240FR500 be used as a direct replacement for MBA02040C3240FRP00?

A: Yes, within the constraints of your circuit design. Both parts share identical resistance values, tolerance, composition, and operating temperature range. The substitute features higher power rating and different temperature coefficient specifications.

Q: What is the significance of the power rating difference (0.4W vs 0.5W)?

A: The substitute part has greater power dissipation capability. If your circuit dissipates less than 0.4W through the resistor, both parts are functionally equivalent. If power dissipation approaches or exceeds 0.4W, the higher-rated substitute provides additional thermal margin.

Q: How does the temperature coefficient difference affect substitution?

A: The MBA02040C3240FRP00 has ±50ppm/°C while SFR16S0003240FR500 has ±100ppm/°C. This means the substitute exhibits twice the resistance change per degree Celsius. For applications requiring high precision across temperature ranges, verify that the ±100ppm/°C specification remains acceptable for your tolerance budget.

Q: Are both parts suitable for automotive applications?

A: The MBA02040C3240FRP00 carries AEC-Q200 automotive qualification. The SFR16S0003240FR500 does not list automotive qualification in the provided specifications. Confirm automotive suitability requirements before substitution in safety-critical automotive circuits.

Q: Do the physical dimensions differ between these parts?

A: Yes. MBA02040C3240FRP00 measures 0.063" Dia x 0.142" L (1.60mm x 3.60mm). SFR16S0003240FR500 measures 0.075" Dia x 0.138" L (1.90mm x 4.60mm). Verify PCB layout and mechanical clearance before substitution.
