Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX31R6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 31.6 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All listed substitute parts meet these core electrical and mechanical specifications. Direct substitutes maintain full AEC-Q200 automotive qualification. The RC0603FR-0731R6L from YAGEO is classified as a similar substitute due to moisture-resistant feature designation rather than explicit AEC-Q200 rating, though it meets all electrical and dimensional parameters.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, the direct substitutes CRCW060331R6FKEA (Vishay Dale), ERJ-3EKF31R6V (Panasonic), and RMCF0603FT31R6 (Stackpole) are fully equivalent to the MCR03EZPFX31R6. All three maintain active product status with ROHS3 compliance and identical electrical specifications.

The RC0603FR-0731R6L from YAGEO meets all electrical and dimensional requirements with the highest inventory availability (256073 Pcs). This part is suitable for applications where AEC-Q200 certification is not mandated, provided design specifications permit moisture-resistant thick film composition.

For immediate availability and active production support, ERJ-3EKF31R6V offers the largest inventory (68346 Pcs) among AEC-Q200 qualified alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0731R6L be used in place of MCR03EZPFX31R6 in automotive applications?

A: RC0603FR-0731R6L meets all electrical parameters (31.6 Ω, ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). However, it lacks explicit AEC-Q200 automotive qualification. Use only if your application does not require AEC-Q200 certification.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist within tolerance. MCR03EZPFX31R6 and ERJ-3EKF31R6V are 0.063" L × 0.031" W (1.60mm × 0.80mm). CRCW060331R6FKEA and RMCF0603FT31R6 are 0.061" L × 0.031" W (1.55mm × 0.80mm). All fit the 0603 (1608 Metric) footprint. Height differences (0.020" to 0.022") are within standard PCB assembly tolerances.

Q: Which substitute offers the best long-term availability?

A: ERJ-3EKF31R6V (Panasonic) and CRCW060331R6FKEA (Vishay Dale) both maintain active product status with substantial inventory levels. ERJ-3EKF31R6V has the highest current stock (68346 Pcs).

Q: Do all substitutes have identical RoHS and REACH compliance?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030.

Q: What is the moisture sensitivity level for all parts?

A: All parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
