Substitute Part Grouping Explanation

Substitute parts for the MF1/4DC1402F are identified as parametric equivalents based on the following criteria:

• Identical resistance value: 14 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Identical package type: Axial Through Hole
• Identical physical dimensions: 0.091" Dia x 0.248" L (2.30mm x 6.30mm)
• Identical automotive qualification: AEC-Q200
• Identical RoHS compliance: ROHS3 Compliant

The substitute parts differ only in packaging format (Cut Tape instead of Bulk), which does not affect electrical or mechanical performance. Both substitute parts are manufactured by the same supplier and maintain full compatibility with the original part specification.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MF1/4DC1402F, MF1/4DCT52A1402F, and MF1/4DCT52R1402F—are active production components from KOA Speer Electronics with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:

• MF1/4DC1402F is supplied in bulk packaging, suitable for high-volume procurement and direct component handling.
• MF1/4DCT52A1402F and MF1/4DCT52R1402F are supplied in cut tape format, suitable for automated assembly processes and tape-and-reel handling.

All parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring suitability for automotive and industrial applications operating within the specified temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can MF1/4DCT52A1402F and MF1/4DCT52R1402F be used interchangeably with MF1/4DC1402F?

A: Yes. All three parts have identical electrical specifications (14 kOhms, ±1%, 0.25W, metal film composition) and mechanical dimensions (0.091" Dia x 0.248" L). The only difference is packaging format: bulk versus cut tape. Electrical performance and circuit compatibility are identical.

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

A: Bulk packaging supplies loose components suitable for manual assembly or bin storage. Cut tape packaging supplies components on continuous tape with carrier, optimized for automated pick-and-place assembly equipment. Both formats contain the same component with identical specifications.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification, confirming compliance with automotive reliability and quality standards. Operating temperature range of -55°C to 155°C supports automotive environmental requirements.

Q: Do these parts meet RoHS compliance requirements?

A: Yes. All three parts are ROHS3 compliant, meeting European Union Restriction of Hazardous Substances directives.

Q: Can I substitute one part number for another in my design?

A: Yes, provided your assembly process accommodates the packaging format. If your process uses automated tape-fed equipment, use cut tape versions (MF1/4DCT52A1402F or MF1/4DCT52R1402F). If your process uses bulk component handling, use MF1/4DC1402F. Electrical and mechanical performance are identical across all three part numbers.
