Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2102 is determined by strict equivalence across the following parameters:

• Resistance value: 21 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: MSL 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Parts are categorized as Direct Manufacturer equivalents (CRCW060321K0FKEA, ERJ-3EKF2102V, RMCF0603FT21K0) or Similar alternatives (AC0603FR-0721KL, CR0603-FX-2102ELF, RC0603FR-0721KL) based on feature alignment and automotive certification status.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive AEC-Q200 compliance, select from the Direct Manufacturer equivalents: CRCW060321K0FKEA (Vishay Dale), ERJ-3EKF2102V (Panasonic), or RMCF0603FT21K0 (Stackpole). All three maintain active product status with high inventory availability and full AEC-Q200 certification.

For non-automotive or general-purpose applications where AEC-Q200 certification is not mandatory, the Similar alternatives AC0603FR-0721KL, CR0603-FX-2102ELF, and RC0603FR-0721KL provide electrical and mechanical equivalence with moisture-resistant features. These parts are suitable for applications where automotive qualification is not required.

All listed substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use AC0603FR-0721KL or RC0603FR-0721KL as direct replacements for MCR03EZPFX2102 in automotive applications?

A: AC0603FR-0721KL and RC0603FR-0721KL are not rated for AEC-Q200 automotive qualification. Use these parts only in non-automotive applications. For automotive designs, select CRCW060321K0FKEA, ERJ-3EKF2102V, or RMCF0603FT21K0.

Q: What is the difference between Direct Manufacturer and Similar substitute categories?

A: Direct Manufacturer substitutes (CRCW060321K0FKEA, ERJ-3EKF2102V, RMCF0603FT21K0) carry full AEC-Q200 automotive certification matching the original part. Similar alternatives (AC0603FR-0721KL, CR0603-FX-2102ELF, RC0603FR-0721KL) meet electrical and mechanical specifications but lack automotive qualification.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are available in 0603 (1608 Metric) package. Packaging formats vary by manufacturer: Vishay Dale, Panasonic, Stackpole, YAGEO, and Bourns offer Tape & Reel (TR) or Cut Tape (CT) options. Confirm packaging availability with your supplier.

Q: Do all substitutes have the same physical dimensions?

A: All parts conform to 0603 (1608 Metric) package specifications. Minor dimensional variations exist within tolerance: length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width is 0.031" to 0.033" (0.80mm to 0.85mm), and height is 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF2102V (Panasonic) has 92,845 pieces in stock, followed by RMCF0603FT21K0 (Stackpole) with 83,961 pieces and CRCW060321K0FKEA (Vishay Dale) with 35,705 pieces.
