MCR03EZPFX1330 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1330 is a 133 Ohms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with an operating temperature range of -55°C to 155°C. The part is currently discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain identical electrical and mechanical specifications for seamless circuit board integration.

Substitute Part Grouping Explanation

Substitution of the MCR03EZPFX1330 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 133 Ohms (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: -55°C to 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity: MSL 1 (exact match required)

All identified substitute parts meet these criteria. Direct substitutes maintain full AEC-Q200 automotive qualification. Similar substitutes maintain all electrical and mechanical specifications but differ in specific feature certifications (Moisture Resistant designation versus AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (AEC-Q200 Qualified):

For automotive applications requiring maintained AEC-Q200 qualification, select from:

• CRCW0603133RFKEA (Vishay Dale) - Active status, 33277 units in stock
• ERJ-3EKF1330V (Panasonic Electronic Components) - Active status, 63114 units in stock
• RMCF0603FT133R (Stackpole Electronics Inc) - Active status, 59066 units in stock

These parts provide direct functional equivalence with full automotive certification continuity.

Alternative Substitutes (Moisture Resistant, Non-AEC-Q200):

For applications where AEC-Q200 certification is not mandatory:

• CR0603-FX-1330ELF (Bourns Inc.) - Active status, 16986 units in stock
• RC0603FR-07133RL (YAGEO) - Active status, 83690 units in stock

These parts maintain all electrical and mechanical specifications with moisture-resistant characteristics but lack specific automotive qualification.

All substitute parts are ROHS3 compliant, MSL 1 rated, and available in Tape & Reel packaging.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1330ELF or RC0603FR-07133RL as replacements for MCR03EZPFX1330 in automotive circuits?

A: These parts 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 from the direct substitutes: CRCW0603133RFKEA, ERJ-3EKF1330V, or RMCF0603FT133R.

Q: Are all substitute parts compatible with the same PCB footprint?

A: All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within tolerance (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm). These variations are within standard PCB design tolerances and do not affect footprint compatibility.

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

A: Direct substitutes (CRCW0603133RFKEA, ERJ-3EKF1330V, RMCF0603FT133R) maintain AEC-Q200 automotive qualification. Similar substitutes (CR0603-FX-1330ELF, RC0603FR-07133RL) maintain all electrical and mechanical specifications but are rated for moisture resistance instead of automotive applications.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All substitute parts have a temperature coefficient of ±100ppm/°C, matching the original MCR03EZPFX1330 specification.

Q: Which substitute has the highest inventory availability?

A: RC0603FR-07133RL (YAGEO) has the highest inventory at 83690 units. For AEC-Q200 qualified parts, ERJ-3EKF1330V (Panasonic) has the highest inventory at 63114 units.
