Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MF1/4DC2R20F is determined by matching the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package case: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The identified substitute part differs only in packaging format (Cut Tape versus Bulk), which does not affect electrical performance or mechanical compatibility in circuit applications. Both parts are from the same manufacturer series and maintain identical component specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MF1/4DC2R20F and MF1/4DCT52R2R20F are active production parts from KOA Speer Electronics, Inc. with identical electrical and mechanical specifications. Selection between these parts is based on procurement and assembly requirements:

• MF1/4DC2R20F (Bulk packaging) is suitable for high-volume applications with manual or bulk handling processes.
• MF1/4DCT52R2R20F (Cut Tape packaging) is optimized for automated pick-and-place assembly operations.

Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification, ensuring regulatory and quality standards are met regardless of packaging selection. The choice between bulk and cut tape formats does not impact circuit performance, reliability, or environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52R2R20F replace MF1/4DC2R20F in circuit applications?

A: Yes. Both parts have identical electrical specifications (2.2 Ohms ±1%, 0.25W, metal film composition) and mechanical dimensions (0.091" Dia x 0.248" L). The difference is packaging format only. Bulk and cut tape versions of the same component are functionally equivalent in circuit design.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging contains loose components suitable for manual assembly or bin storage. Cut Tape packaging places components on carrier tape at specified intervals, optimized for automated assembly equipment. Both formats contain identical parts with the same electrical performance.

Q: Are both parts automotive qualified?

A: Yes. Both MF1/4DC2R20F and MF1/4DCT52R2R20F meet AEC-Q200 automotive qualification standards and are suitable for automotive circuit applications.

Q: Do both parts have the same temperature operating range?

A: Yes. Both parts operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C, ensuring consistent performance across the full automotive temperature spectrum.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under the same ECCN (EAR99) and HTSUS (8533.21.0090) codes.
