Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/8K4701FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

Resistance value: 4.7 kOhms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Termination count: 2

All substitute parts listed meet these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within acceptable tolerances, packaging format (Tape & Reel vs. Cut Tape), and additional certifications (such as AEC-Q200 automotive qualification or moisture resistance features) do not disqualify substitution but may be relevant for specific application contexts.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMC1/8K4701FTP with any of the listed parts in my circuit?

A: Yes, all listed substitute parts meet the core electrical specifications (4.7 kΩ ±1%, 0.25W, thick film, 1206 package, ±100ppm/°C, -55°C to 155°C operating range). Physical dimension variations are within acceptable tolerances for 1206 package class components.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Both are standard SMD packaging formats. Tape & Reel is continuous reel packaging suitable for high-volume automated assembly. Cut Tape & Digi-Reel provides smaller quantity options with individual tape segments. Selection depends on production volume and assembly equipment compatibility, not electrical performance.

Q: Why is ERJ-8ENF4701V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development for this part number. While electrically equivalent and currently in stock (81875 units), it should be used only for legacy system maintenance or replacement applications. For new designs, select from Active status alternatives.

Q: Do the automotive AEC-Q200 qualified parts (KTR18EZPF4701, RMCF1206FT4K70) work in non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of standard industrial specifications. Parts qualified for automotive use are fully compatible with general industrial, consumer, and commercial applications.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts carry this rating, eliminating moisture-related compatibility concerns.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts are confirmed RoHS3 compliant. The main part (RMC1/8K4701FTP) carries REACH Unaffected status, and all substitutes maintain equivalent environmental compliance classifications.
