Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX7681 is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.68 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitutes meet these core electrical and mechanical specifications. Substitute parts are categorized as either Direct (fully equivalent with automotive AEC-Q200 rating) or Similar (equivalent specifications with alternative feature sets such as moisture resistance instead of automotive certification).

Parameter Comparison

Engineering Selection Recommendations

Direct substitutes with automotive AEC-Q200 certification are CRCW06037K68FKEA (Vishay Dale), ERJ-3EKF7681V (Panasonic Electronic Components), and RMCF0603FT7K68 (Stackpole Electronics Inc). All three maintain active product status and full compliance with ROHS3 and automotive standards.

Similar substitutes CR0603-FX-7681ELF (Bourns Inc.) and RC0603FR-077K68L (YAGEO) are active products with identical electrical specifications and ROHS3 compliance. These parts feature moisture-resistant construction rather than automotive AEC-Q200 certification. Selection between direct and similar substitutes depends on application-specific automotive qualification requirements.

All substitute parts are available in higher inventory quantities than the discontinued MCR03EZPFX7681, supporting production continuity.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-7681ELF or RC0603FR-077K68L in automotive applications requiring AEC-Q200?

A: CR0603-FX-7681ELF and RC0603FR-077K68L are rated for moisture resistance rather than automotive AEC-Q200 certification. For applications with explicit AEC-Q200 requirements, use CRCW06037K68FKEA, ERJ-3EKF7681V, or RMCF0603FT7K68.

Q: Are all substitute parts compatible with the original 0603 package footprint?

A: All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance: length ranges from 0.061" to 0.063" and height from 0.020" to 0.022". These variations are within standard PCB design tolerances for 0603 components.

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

A: Cut Tape (CT) packaging is suitable for small-quantity applications and manual assembly. Tape & Reel (TR) packaging is optimized for high-volume automated assembly processes. Both formats contain identical components; selection depends on production volume and assembly equipment.

Q: Do all substitutes have the same moisture sensitivity level?

A: All listed parts, including the original MCR03EZPFX7681, have MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-077K68L (YAGEO) has the highest inventory at 40,941 pieces, followed by ERJ-3EKF7681V (Panasonic) at 53,466 pieces and CRCW06037K68FKEA (Vishay Dale) at 29,333 pieces.
