Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MFS1/2DCT52R1000F are identified based on strict equivalence of the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package: Axial through-hole
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• Regulatory compliance: ROHS3 Compliant

The SFR16S0001000FR500 from Vishay Beyschlag/Draloric/BC Components meets all these electrical and mechanical requirements, making it a direct functional equivalent for applications requiring the MFS1/2DCT52R1000F.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/2DCT52R1000F and SFR16S0001000FR500 are active production components with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

• PCB layout constraints: The SFR16S0001000FR500 has a smaller physical footprint (1.90mm diameter vs. 2.30mm), which may be advantageous in space-constrained designs.
• Supply chain availability: The SFR16S0001000FR500 has higher inventory availability (49,288 units vs. 748 units).
• Manufacturer qualification requirements: The MFS1/2DCT52R1000F carries AEC-Q200 automotive qualification; verify whether the application requires this specific certification.
• Lead time and cost considerations: Evaluate supplier delivery schedules and unit pricing for your procurement volume.

Frequently Asked Questions (FAQ)

Q: Can the SFR16S0001000FR500 be used as a direct replacement for the MFS1/2DCT52R1000F?

A: Yes. Both resistors share identical electrical specifications: 100 Ohms ±1% tolerance, 0.5W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are ROHS3 compliant with 2 terminations in axial package configuration.

Q: What is the difference in physical size between these parts?

A: The MFS1/2DCT52R1000F measures 0.091" diameter x 0.248" length (2.30mm x 6.30mm). The SFR16S0001000FR500 measures 0.075" diameter x 0.138" length (1.90mm x 4.60mm). The Vishay part is smaller and may require PCB layout verification if space is critical.

Q: Does the SFR16S0001000FR500 meet automotive AEC-Q200 requirements?

A: The provided specifications for the SFR16S0001000FR500 do not list AEC-Q200 qualification. If automotive AEC-Q200 certification is a mandatory requirement, the MFS1/2DCT52R1000F should be specified.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0090. No regulatory differences exist between the two components.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For automotive applications requiring AEC-Q200 certification, use the MFS1/2DCT52R1000F. For general industrial applications where space optimization and supply availability are priorities, the SFR16S0001000FR500 is suitable.
