Substitute Part Grouping Explanation

Substitution eligibility for the MF1/2DCT52R2R00F is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

The identified substitute part SFR25H0002008FR500 meets all mandatory electrical and mechanical criteria for direct substitution. Variations in temperature coefficient and physical dimensions do not affect functional equivalence when the above parameters are satisfied.

Engineering Selection Recommendations

Both the MF1/2DCT52R2R00F and SFR25H0002008FR500 are active production components with full ROHS3 compliance and REACH unaffected status, making either suitable for applications requiring regulatory compliance. Selection between these parts should be based on:

• PCB layout constraints: The SFR25H0002008FR500 features a smaller physical footprint (2.50mm diameter vs. 4.60mm), which may be advantageous in space-constrained designs.
• Temperature stability requirements: The MF1/2DCT52R2R00F offers superior temperature coefficient performance (±100ppm/°C vs. ±250ppm/°C), which may be critical for precision analog circuits.
• Supply chain availability: Both parts maintain active inventory status; selection may depend on supplier lead times and procurement preferences.

Frequently Asked Questions (FAQ)

Q: Can SFR25H0002008FR500 be used as a direct replacement for MF1/2DCT52R2R00F?

A: Yes. Both parts share identical electrical specifications (2 Ohms, ±1%, 0.5W, metal film composition) and operate across the same temperature range (-55°C ~ 155°C). Both are ROHS3 compliant and REACH unaffected. The primary differences are physical dimensions and temperature coefficient, which do not affect functional equivalence in standard applications.

Q: What are the physical dimension differences between these parts?

A: The MF1/2DCT52R2R00F measures 0.138" diameter x 0.354" length (4.60mm x 9.00mm). The SFR25H0002008FR500 measures 0.098" diameter x 0.256" length (2.50mm x 6.50mm). The Vishay part is approximately 28% smaller in diameter and 27% shorter in length. Both are axial through-hole components compatible with standard PCB hole spacing.

Q: How do temperature coefficients affect substitution?

A: The MF1/2DCT52R2R00F has a temperature coefficient of ±100ppm/°C, while the SFR25H0002008FR500 has ±250ppm/°C. For applications requiring high precision across wide temperature ranges, the KOA part offers superior stability. For general-purpose applications, both coefficients are acceptable within standard operating conditions.

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

A: Both parts are active production components with full compliance certifications (ROHS3, REACH unaffected). Selection for high-reliability applications should be based on specific design requirements, including temperature stability needs and physical space constraints, rather than substitution eligibility alone.
