Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1962 is determined by strict equivalence across the following parameters:

• Resistance value: 19.6 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
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All substitute parts listed meet these electrical and mechanical specifications. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer features (Automotive AEC-Q200, Anti-Sulfur, Moisture Resistant), and minor dimensional tolerances do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the MCR03EZPFX1962, the following selection criteria apply:

Active Status Priority: CRCW060319K6FKEA, ERJ-3EKF1962V, RMCF0603FT19K6, CR0603-FX-1962ELF, and RC0603FR-0719K6L are all in active production status and represent the primary substitution options.

Automotive AEC-Q200 Compliance: CRCW060319K6FKEA, ERJ-3EKF1962V, and RMCF0603FT19K6 carry explicit AEC-Q200 automotive qualification, matching the original part's automotive-grade specification.

RoHS3 Compliance: All substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring regulatory and environmental compatibility.

Packaging Considerations: CRCW060319K6FKEA offers Cut Tape & Digi-Reel packaging similar to the original format. Remaining substitutes are supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the MCR03EZPFX1962?

A: Yes. All listed substitute parts meet the core electrical specifications: 19.6 kOhms ±1% resistance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Functional equivalence is guaranteed across these parameters.

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

A: Cut Tape packaging is supplied in smaller quantities on individual tape strips, suitable for manual assembly or small production runs. Tape & Reel packaging is supplied on continuous reels, optimized for high-volume automated assembly. Both formats contain identical components; the difference is in delivery and handling format only.

Q: Does the "Automotive AEC-Q200" feature matter for my application?

A: AEC-Q200 is an automotive industry qualification standard. If your application requires automotive-grade components, select CRCW060319K6FKEA, ERJ-3EKF1962V, or RMCF0603FT19K6. For non-automotive applications, all substitutes are functionally equivalent.

Q: Are there any differences in the physical dimensions between substitute parts?

A: Minor dimensional variations exist within the 0603 package specification. The MCR03EZPFX1962 measures 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" max height. CRCW060319K6FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" max height. These variations remain within standard 0603 tolerances and do not affect PCB layout or assembly compatibility.

Q: What does "Moisture Resistant" or "Anti-Sulfur" mean on some substitute parts?

A: These are additional material features that enhance component reliability in specific environmental conditions. "Moisture Resistant" provides enhanced protection against moisture ingress. "Anti-Sulfur" provides protection against sulfur-containing atmospheric corrosion. These features do not affect electrical equivalence and represent manufacturing enhancements beyond the base specification.

Q: Which substitute part has the highest inventory availability?

A: ERJ-3EKF1962V (Panasonic) has 110,951 pieces in stock, followed by RC0603FR-0719K6L (YAGEO) with 95,174 pieces. CRCW060319K6FKEA (Vishay Dale) has 33,438 pieces available.
