Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX6812 is determined by strict equivalence across the following critical parameters:

• Resistance value: 68.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed below meet these criteria without exception. Packaging format (Cut Tape, Tape & Reel, or Digi-Reel) and specific feature designations (Automotive AEC-Q200 vs. Moisture Resistant vs. Anti-Sulfur) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the MCR03EZPFX6812, the following selection criteria apply:

Active Status Priority: RMCF0603FT68K1 (Stackpole Electronics Inc, Tape & Reel) and ERJ-3EKF6812V (Panasonic Electronic Components, Tape & Reel) are currently in active production with substantial inventory availability (427,377 and 28,499 units respectively), making them the primary choices for new designs and production replenishment.

Alternative Active Sources: CRCW060368K1FKEA (Vishay Dale, Cut Tape & Digi-Reel), RC0603FR-0768K1L (YAGEO, Cut Tape & Digi-Reel), RMCF0603FG68K1 (Stackpole Electronics Inc, Cut Tape), CR0603-FX-6812ELF (Bourns Inc., Tape & Reel), and RC1608F6812CS (Samsung Electro-Mechanics, Cut Tape) are all active and provide additional sourcing flexibility.

Compliance Assurance: All listed substitutes maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications. Automotive-qualified variants (CRCW060368K1FKEA, CRCW060368K1FKEB, ERJ-3EKF6812V, RMCF0603FG68K1, RMCF0603FT68K1) carry AEC-Q200 certification. Non-automotive variants (CR0603-FX-6812ELF, RC0603FR-0768K1L, RC1608F6812CS) feature moisture-resistant construction.

Packaging Considerations: Selection between Cut Tape, Tape & Reel, and Digi-Reel formats depends on assembly process requirements and volume specifications. All formats are mechanically and electrically equivalent.

Frequently Asked Questions (FAQ)

Q: Can I substitute the MCR03EZPFX6812 with any of the listed parts?

A: Yes. All listed parts meet identical electrical and mechanical specifications: 68.1 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Direct substitution is electrically and mechanically valid.

Q: What is the difference between Automotive AEC-Q200 and Moisture Resistant variants?

A: Both meet the same electrical specifications. AEC-Q200 variants (Rohm MCR/TRR series, Vishay CRCW, Panasonic ERJ-3EK, Stackpole RMCF) are qualified for automotive applications. Moisture Resistant variants (Bourns CR0603, YAGEO RC, Samsung RC) emphasize environmental protection. Selection depends on application requirements, not electrical compatibility.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect circuit performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical performance is identical across all packaging types.

Q: Which substitute offers the best availability?

A: RMCF0603FT68K1 (Stackpole Electronics Inc) has the highest inventory at 427,377 units. ERJ-3EKF6812V (Panasonic) offers 28,499 units. Both are in active production.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use a discontinued part as a substitute?

A: TRR03EZPF6812 (Rohm, Obsolete) and CRCW060368K1FKEB (Vishay, Discontinued at DiGi Electronics) are electrically equivalent but may have limited availability. Active-status parts are recommended for new designs and ongoing production.
