• HTSUS: 8533.21.0090

Packaging Difference: The primary distinction between the main part and substitute is the packaging format: MF1/4DC3010F is supplied in bulk packaging, while MF1/4DCT52R3010F is supplied in cut tape (CT) format. Both formats contain identical components with no electrical or mechanical differences.

Parameter Comparison

Engineering Selection Recommendations

Both MF1/4DC3010F and MF1/4DCT52R3010F are active production components from KOA Speer Electronics, Inc., with full AEC-Q200 automotive qualification and ROHS3 compliance. The electrical and mechanical specifications are identical across both parts.

Selection between these parts should be based on procurement and assembly requirements:

• MF1/4DC3010F (Bulk packaging): Suitable for high-volume applications where components are supplied in loose form and require manual handling or custom packaging integration.

• MF1/4DCT52R3010F (Cut Tape packaging): Suitable for automated assembly processes where cut tape format enables direct feeding into pick-and-place equipment, reducing manual handling and improving assembly efficiency.

Both parts meet identical electrical performance criteria and automotive compliance standards. The choice between them is determined by manufacturing process requirements and supply chain logistics rather than technical performance.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R3010F be used as a direct replacement for MF1/4DC3010F?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus cut tape). Direct substitution is valid from a technical standpoint. Assembly process compatibility should be verified based on your manufacturing equipment.

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

A: Bulk packaging supplies loose components in a container, suitable for manual assembly or custom packaging workflows. Cut tape packaging supplies components on continuous tape in standardized lengths, designed for automated pick-and-place assembly equipment. The resistor components themselves are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both MF1/4DC3010F and MF1/4DCT52R3010F carry AEC-Q200 qualification, confirming suitability for automotive environments across the specified operating temperature range of -55°C to 155°C.

Q: Do these parts have identical electrical performance?

A: Yes. Both parts have identical resistance value (301 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C).

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.

Q: Which part should I select for my application?

A: Selection depends on your assembly process. If using automated assembly with tape-fed equipment, select MF1/4DCT52R3010F. If using manual assembly or custom packaging workflows, select MF1/4DC3010F. Both deliver identical electrical performance.
