Substitute Part Grouping Explanation

Substitution eligibility for the MF1/4DC4701F is determined by strict equivalence across the following critical parameters: resistance value (4.7 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), package configuration (axial through-hole), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The identified substitute differs only in packaging format (Cut Tape versus Bulk), which does not affect electrical performance or mechanical compatibility. Both parts share identical part number nomenclature within the MF series, confirming parametric equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both MF1/4DC4701F and MF1/4DCT52R4701F are active products from KOA Speer Electronics with full ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts should be based on procurement and assembly requirements. The bulk-packaged MF1/4DC4701F is suitable for manual assembly or low-volume applications. The cut-tape packaged MF1/4DCT52R4701F accommodates automated pick-and-place assembly processes and offers higher current inventory availability (4648 units versus 1043 units). Both parts satisfy identical electrical and mechanical specifications for automotive circuit applications operating within the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R4701F replace MF1/4DC4701F in production assemblies? A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications. The difference is packaging format only. Cut-tape packaging is compatible with automated assembly equipment, while bulk packaging is suited for manual or semi-automated processes.

Q: Are there any performance differences between bulk and cut-tape versions? A: No. Electrical performance, tolerance, temperature coefficient, and operating range are identical. Packaging format does not affect component function or reliability.

Q: Which part should be selected for automated assembly? A: MF1/4DCT52R4701F (cut-tape format) is designed for automated pick-and-place equipment and offers higher inventory availability.

Q: Are both parts suitable for automotive applications? A: Yes. Both parts carry AEC-Q200 qualification and are rated for automotive use across the -55°C to 155°C operating temperature range.

Q: What is the significance of the ±1% tolerance specification? A: The ±1% tolerance indicates precision-grade resistor performance, ensuring resistance values remain within 4.653 kOhms to 4.747 kOhms across the operating temperature range and component lifetime.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the circuit design accommodates the axial through-hole package configuration and the specified power dissipation does not exceed 0.25W under operating conditions.
