Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Resistance value: 21.5 kOhms
Tolerance: ±1%
Power rating: 0.1W (1/10W)
Package: 0603 (1608 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical specifications. Variations in features (such as anti-sulfur coating or automotive AEC-Q200 rating) and packaging format (Tape & Reel versus Cut Tape) do not affect functional substitutability but may influence application suitability and procurement logistics.

Engineering Selection Recommendations

All substitute parts listed are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

For applications requiring automotive AEC-Q200 qualification, select from: ERJ-3EKF2152V (Panasonic), AC0603FR-0721K5L (YAGEO), CRCW060321K5FKEA (Vishay Dale), or RMCF0603FT21K5 (Stackpole Electronics Inc).

For applications without automotive qualification requirements, CR0603-FX-2152ELF (Bourns), RC0603FR-0721K5L (YAGEO), and RC1608F2152CS (Samsung Electro-Mechanics) are functionally equivalent alternatives.

Packaging format selection depends on procurement workflow: Tape & Reel format suits high-volume automated assembly, while Cut Tape format accommodates smaller quantity orders.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF2152V replace ERJ-S03F2152V directly?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (21.5 kOhms ±1%, 0.1W, ±100ppm/°C), operate across -55°C to 155°C, and are packaged in 0603 (1608 Metric) format. The primary difference is the series designation (ERJ-3EK versus ERJ-S03) and anti-sulfur coating on the ERJ-S03F2152V. Both carry AEC-Q200 automotive qualification.

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

A: Tape & Reel packaging supplies components on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape and Digi-Reel formats provide components in smaller quantities on cut segments of carrier tape, typically for lower-volume applications or manual assembly. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Are non-AEC-Q200 parts suitable for automotive applications?

A: Component selection for automotive applications must follow design specifications and qualification requirements established by the original equipment manufacturer. Parts without AEC-Q200 rating (CR0603-FX-2152ELF, RC0603FR-0721K5L, RC1608F2152CS) may not meet automotive reliability and testing standards. Consult application requirements before substitution.

Q: Do all substitute parts have the same physical dimensions?

A: All parts conform to 0603 (1608 Metric) package specification. Minor dimensional variations exist: CRCW060321K5FKEA measures 0.061" L × 0.033" W with 0.020" max height, while most others measure 0.063" L × 0.031" W with 0.022" max height. These variations remain within standard 0603 package tolerances and do not affect PCB footprint compatibility.

Q: Which substitute offers the highest inventory availability?

A: RC0603FR-0721K5L (YAGEO) provides the largest stock quantity at 1,695,486 units. ERJ-3EKF2152V (Panasonic) offers 74,170 units, and CR0603-FX-2152ELF (Bourns) provides 77,247 units. Inventory levels should be verified with suppliers for current availability.
