Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCR03EZPFX9093 is determined by strict equivalence across the following critical parameters:

• Resistance value: 909 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 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 substitute parts listed below meet these exact specifications. Direct substitutes maintain AEC-Q200 automotive qualification. Similar substitutes provide equivalent electrical performance with alternative feature sets (moisture resistance instead of automotive rating) but remain mechanically and electrically compatible.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, CRCW0603909KFKEA (Vishay Dale) and ERJ-3EKF9093V (Panasonic Electronic Components) are direct equivalents with active product status and full automotive certification parity to the original MCR03EZPFX9093.

For non-automotive applications or where moisture resistance is a design requirement, CR0603-FX-9093ELF (Bourns Inc.) and RC0603FR-07909KL (YAGEO) provide equivalent electrical performance with moisture-resistant thick film composition. These parts maintain identical resistance, tolerance, power rating, package, and temperature specifications while offering alternative feature sets.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-9093ELF or RC0603FR-07909KL in place of MCR03EZPFX9093 in automotive applications?

A: CR0603-FX-9093ELF and RC0603FR-07909KL are electrically and mechanically equivalent but lack AEC-Q200 automotive certification. Use only if your application does not require automotive qualification. For automotive designs, select CRCW0603909KFKEA or ERJ-3EKF9093V.

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

A: All substitute parts use 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W). Height variations are minimal (0.020" to 0.022" seated maximum) and do not affect PCB assembly compatibility.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CRCW0603909KFKEA, ERJ-3EKF9093V) maintain AEC-Q200 automotive rating identical to the original part. Similar substitutes (CR0603-FX-9093ELF, RC0603FR-07909KL) provide equivalent electrical specifications with moisture-resistant composition instead of automotive qualification.

Q: Do all parts meet the same tolerance and temperature coefficient specifications?

A: Yes. All listed parts maintain ±1% tolerance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range, ensuring functional equivalence in circuit performance.

Q: Are there inventory considerations for part selection?

A: YAGEO RC0603FR-07909KL offers the highest inventory availability (192,688 pcs), followed by Vishay Dale CRCW0603909KFKEA (57,671 pcs) and Panasonic ERJ-3EKF9093V (39,474 pcs). Bourns CR0603-FX-9093ELF has lower availability (12,692 pcs).
