Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MFS1/2DCT52R1001F are qualified based on the following critical parameters:

• Resistance Value: 1 kOhms (exact match required)
• Tolerance: ±1% (ensures precision matching)
• Power Rating: 0.5W / 1/2W (thermal and electrical performance)
• Composition: Metal Film (stability and temperature coefficient characteristics)
• Package: Axial through-hole (mechanical fit and PCB compatibility)
• Temperature Coefficient: ±100ppm/°C (frequency response and drift characteristics)
• Operating Temperature Range: -55°C to 155°C (environmental suitability)
• Compliance: ROHS3 Compliant, REACH Unaffected (regulatory alignment)

The SFR16S0001001FR500 from Vishay Beyschlag/Draloric/BC Components meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the MFS1/2DCT52R1001F and SFR16S0001001FR500 are Active products with equivalent electrical specifications and regulatory compliance. Selection between these parts should be based on:

• Availability: SFR16S0001001FR500 has higher inventory (43,986 units) compared to MFS1/2DCT52R1001F (979 units)
• Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, suitable for regulated applications
• Automotive Qualification: MFS1/2DCT52R1001F carries explicit AEC-Q200 automotive qualification; SFR16S0001001FR500 does not list this certification in provided specifications
• Physical Dimensions: SFR16S0001001FR500 has smaller axial dimensions (0.075" Dia x 0.138" L) compared to MFS1/2DCT52R1001F (0.091" Dia x 0.248" L), which may affect PCB layout considerations

Frequently Asked Questions (FAQ)

Q: Can SFR16S0001001FR500 replace MFS1/2DCT52R1001F in automotive applications?

A: Both parts share identical electrical specifications (1 kOhms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C). However, MFS1/2DCT52R1001F carries AEC-Q200 automotive qualification while SFR16S0001001FR500 does not list this certification. Application requirements determine whether AEC-Q200 qualification is mandatory.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use axial through-hole packaging with 2 terminations. The SFR16S0001001FR500 has smaller physical dimensions (0.075" Dia x 0.138" L versus 0.091" Dia x 0.248" L). This difference does not affect electrical compatibility but may impact PCB layout and mechanical mounting considerations.

Q: Do both parts meet regulatory requirements?

A: Both MFS1/2DCT52R1001F and SFR16S0001001FR500 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic components.

Q: What is the temperature coefficient significance?

A: Both parts specify ±100ppm/°C temperature coefficient, ensuring equivalent frequency response and resistance drift characteristics across the -55°C to 155°C operating range.

Q: Which part should be selected for new designs?

A: Selection depends on specific application requirements. For automotive applications requiring AEC-Q200 certification, MFS1/2DCT52R1001F is specified. For general industrial applications where AEC-Q200 is not required, SFR16S0001001FR500 offers higher availability and equivalent electrical performance.
