Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1/4DCT52R2004F is determined by the following critical parameters:

• Resistance value: 2 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial Through-Hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The HVR3700002004FR500 meets all substitution criteria. While the power rating differs (0.5W versus 0.25W), the higher power rating of the substitute part is acceptable for applications designed for the 0.25W specification, as it provides additional thermal margin and pulse withstanding capability without altering the electrical performance of the circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DCT52R2004F and HVR3700002004FR500 are active production components with ROHS3 compliance and REACH unaffected status. The MF1/4DCT52R2004F carries AEC-Q200 automotive qualification, while the HVR3700002004FR500 includes flame retardant coating, high voltage, and pulse withstanding features. Selection between these parts should be based on specific application requirements regarding automotive certification, thermal performance margin, and physical dimensions. The substitute part's higher power rating and additional safety features may provide operational advantages in demanding environments, while the main part's lower temperature coefficient may be preferred for precision applications requiring tighter stability.

Frequently Asked Questions (FAQ)

Q: Can the HVR3700002004FR500 be used as a direct replacement for the MF1/4DCT52R2004F?

A: Yes, the HVR3700002004FR500 is electrically equivalent for the critical parameters: 2 MOhms resistance, ±1% tolerance, metal film composition, and axial through-hole package. Both parts operate across the same temperature range and meet ROHS3 compliance requirements.

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

A: The MF1/4DCT52R2004F measures 0.091" diameter × 0.248" length (2.30mm × 6.30mm). The HVR3700002004FR500 measures 0.157" diameter × 0.394" length (4.00mm × 10.00mm). The substitute part is physically larger due to its higher power rating.

Q: Why does the substitute part have a higher temperature coefficient?

A: The HVR3700002004FR500 has a temperature coefficient of ±200ppm/°C compared to the main part's ±100ppm/°C. This difference reflects the design characteristics of the respective manufacturers' metal film resistor technologies. For applications requiring tighter temperature stability, the main part specification should be maintained.

Q: Are both parts suitable for automotive applications?

A: The MF1/4DCT52R2004F carries AEC-Q200 automotive qualification. The HVR3700002004FR500 does
