Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MFS1/2DCT52R1003F is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 kOhms (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)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The SFR16S0001003FR500 manufactured by Vishay Beyschlag/Draloric/BC Components meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The SFR16S0001003FR500 is a direct functional equivalent to the MFS1/2DCT52R1003F. Both components are active production parts with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the SFR16S0001003FR500 be used as a direct replacement for the MFS1/2DCT52R1003F?

A: Yes. Both components share identical electrical specifications (100 kOhms ±1%, 0.5W metal film), temperature characteristics (±100ppm/°C, -55°C to 155°C operating range), and compliance certifications (ROHS3, REACH unaffected). The axial through-hole package configuration is identical, enabling direct board-level substitution.

Q: Are there physical dimension differences between these parts?

A: Physical dimensions differ slightly. The MFS1/2DCT52R1003F measures 0.091" diameter × 0.248" length (2.30mm × 6.30mm), while the SFR16S0001003FR500 measures 0.075" diameter × 0.138" length (1.90mm × 4.60mm). Both are axial through-hole components suitable for standard PCB hole spacing. Verify PCB layout clearances if space constraints exist.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant and REACH unaffected. The MFS1/2DCT52R1003F carries AEC-Q200 automotive qualification. Both are classified as EAR99 for export control purposes and share the same HTSUS code (8533.21.0090).

Q: Are these parts suitable for automotive applications?

A: The MFS1/2DCT52R1003F is explicitly qualified to AEC-Q200 automotive standards. The SFR16S0001003FR500 does not list automotive qualification in the provided specifications. Automotive application requirements should be confirmed with the component manufacturer or supplier before substitution in safety-critical circuits.
