Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX9103 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 910 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All substitute parts listed meet these criteria. The CRCW0603910KFKEA, ERJ-3EKF9103V, and RMCF0603FT910K are direct equivalents with AEC-Q200 automotive rating. The RC0603FR-07910KL is a similar substitute with moisture-resistant composition but without explicit AEC-Q200 rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (AEC-Q200 Rated):

The CRCW0603910KFKEA (Vishay Dale), ERJ-3EKF9103V (Panasonic Electronic Components), and RMCF0603FT910K (Stackpole Electronics Inc) are direct functional equivalents with active product status and full AEC-Q200 automotive compliance. These parts are recommended for applications requiring automotive-grade reliability and certification continuity with the original MCR03EZPFX9103 specification.

Alternative Substitute (Moisture-Resistant):

The RC0603FR-07910KL (YAGEO) meets all electrical and mechanical parameters with moisture-resistant composition. This part lacks explicit AEC-Q200 rating but maintains ROHS3 compliance and full parameter equivalence. Selection of this part should be based on application requirements where automotive certification is not mandatory.

Availability Consideration:

All substitute parts are in active production with substantial inventory availability, ensuring supply chain continuity for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can the CRCW0603910KFKEA directly replace the MCR03EZPFX9103 in automotive applications?

A: Yes. The CRCW0603910KFKEA is a direct equivalent with identical electrical specifications (910 kOhms ±1%, 0.1W), matching package (0603), and AEC-Q200 automotive certification. No circuit modifications are required.

Q: What is the difference between the ERJ-3EKF9103V and RC0603FR-07910KL?

A: Both parts match the MCR03EZPFX9103 in resistance, tolerance, power rating, and package. The ERJ-3EKF9103V carries AEC-Q200 automotive rating, while the RC0603FR-07910KL is specified as moisture-resistant without explicit automotive certification. Selection depends on application requirements.

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

A: The CRCW0603910KFKEA and ERJ-3EKF9103V are supplied in Tape & Reel (TR) format. The RMCF0603FT910K is available in Cut Tape (CT) & Digi-Reel format. The RC0603FR-07910KL is supplied in Tape & Reel (TR) format. Packaging selection should align with assembly process requirements.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original MCR03EZPFX9103 environmental specifications.

Q: Can I use the RC0603FR-07910KL in place of the MCR03EZPFX9103 in a non-automotive application?

A: Yes. The RC0603FR-07910KL meets all electrical and mechanical parameters. For applications not requiring AEC-Q200 certification, this part is functionally equivalent and offers high inventory availability.
