Substitute Part Grouping Explanation

Substitution eligibility for the MF1/4DC4753F is determined by strict equivalence across the following critical parameters:

• Resistance value: 475 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W/1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package/Case: Axial (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Physical dimensions: 0.091" Dia × 0.248" L (exact match required)

The identified substitute part differs only in packaging format (Cut Tape versus Bulk), which does not affect electrical performance or mechanical compatibility. Both parts are manufactured by KOA Speer Electronics, Inc., maintain active production status, and carry identical compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DC4753F and MF1/4DCT52R4753F are suitable for applications requiring a 475 kOhms ±1% metal film resistor with automotive-grade reliability. Selection between these parts should be based on procurement and assembly requirements:

The MF1/4DC4753F in bulk packaging is appropriate for high-volume manufacturing environments with automated handling systems. The MF1/4DCT52R4753F in cut tape packaging is suitable for lower-volume production runs, manual assembly operations, or applications requiring component-level traceability through tape reel management.

Both parts maintain identical electrical performance, mechanical compatibility, and compliance certifications. The choice between them does not affect circuit functionality, thermal performance, or reliability characteristics. Current inventory levels (1,028 units bulk; 5,415 units cut tape) may influence procurement decisions based on lead time and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R4753F be used as a direct replacement for MF1/4DC4753F?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus cut tape). They are interchangeable in circuit design and PCB assembly.

Q: Does packaging format affect electrical performance?

A: No. Packaging format is a supply chain and assembly consideration only. Electrical specifications, tolerance, temperature coefficient, and power rating are identical between bulk and cut tape versions.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification and are rated for the full automotive temperature range of -55°C to 155°C.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging is used for high-volume automated assembly. Cut tape packaging places components on carrier tape in precise intervals, suitable for lower-volume production or manual assembly workflows.

Q: Do these parts require any special handling or storage considerations?

A: Both parts are passive resistors with no special moisture sensitivity (MSL: Not Applicable). Standard component storage practices apply.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected.
