Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX7R50 is determined by strict equivalence across the following parameters:

• Resistance value: 7.5 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical requirements. Variations in temperature coefficient, RoHS compliance status, and physical dimensions within tolerance are noted but do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict AEC-Q200 automotive qualification with ±100ppm/°C temperature coefficient, MCR03ERTFL7R50 (Rohm Semiconductor) or CRCW06037R50FKEA (Vishay Dale) are direct equivalents. Both parts are ROHS3 compliant and maintain identical electrical specifications.

RC0603FR-077R5L (YAGEO) provides functional equivalence with identical resistance, tolerance, power rating, and operating temperature range. This part carries ROHS3 compliance and offers the highest inventory availability. The temperature coefficient of ±200ppm/°C and absence of specified AEC-Q200 rating should be evaluated against application requirements.

For new designs or applications where RoHS3 compliance is mandatory, CRCW06037R50FKEA or RC0603FR-077R5L are preferred due to active product status and sustained availability.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTFL7R50 directly replace MCR03EZPFX7R50?

A: Yes. Both parts are manufactured by Rohm Semiconductor with identical electrical specifications (7.5 Ohms ±1%, 0.1W, ±100ppm/°C) and AEC-Q200 automotive qualification. The primary difference is RoHS compliance status (MCR03ERTFL7R50 is ROHS3 compliant).

Q: What is the difference between CRCW06037R50FKEA and RC0603FR-077R5L?

A: Both are functionally equivalent 7.5 Ohm ±1% 0.1W 0603 resistors. CRCW06037R50FKEA (Vishay Dale) carries AEC-Q200 automotive qualification with ±100ppm/°C temperature coefficient. RC0603FR-077R5L (YAGEO) has ±200ppm/°C temperature coefficient and does not specify AEC-Q200 rating. Selection depends on automotive qualification requirements and temperature stability specifications.

Q: Are all substitute parts in the same 0603 package?

A: Yes. All substitute parts use the 0603 (1608 Metric) package. Physical dimensions vary slightly within manufacturing tolerance (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but all are mechanically compatible with 0603 footprints.

Q: Which substitute part has the best availability?

A: RC0603FR-077R5L (YAGEO) has the highest inventory availability at 183,465 pieces. CRCW06037R50FKEA (Vishay Dale) has 48,774 pieces available. Both Rohm Semiconductor parts are discontinued or have limited stock.

Q: Can I use these parts in non-automotive applications?

A: Yes. All substitute parts meet the electrical and thermal specifications required for general industrial and consumer applications. AEC-Q200 qualification is not necessary for non-automotive use.
