Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF0805FT357R is determined by strict equivalence across the following parameters:

• Resistance value: 357 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical requirements. Variations in physical dimensions (height, length, width) within standard tolerances do not affect substitutability. Differences in automotive certification (AEC-Q200 presence or absence) and additional features (high voltage capability, moisture resistance) are noted but do not preclude substitution when the base electrical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from CRCW0805357RFKEA (Vishay Dale), ERJ-6ENF3570V (Panasonic Electronic Components), or KTR10EZPF3570 (Rohm Semiconductor). All three maintain active production status and full compliance with automotive standards.

CRCW0805357RFKEA offers the lowest seated height (0.50mm) and highest inventory availability (14,924 pcs), making it suitable for space-constrained PCB layouts and applications with extended lead time requirements.

ERJ-6ENF3570V provides moisture-resistant construction and maintains the highest inventory stock (31,324 pcs), supporting high-volume production schedules.

KTR10EZPF3570 includes high voltage capability in addition to AEC-Q200 rating, providing enhanced performance margin for applications subject to transient voltage stress.

For non-automotive applications where AEC-Q200 certification is not required, RC0805FR-07357RL (YAGEO) offers moisture-resistant thick film construction with the largest available inventory (61,108 pcs) and active production status.

MCR10ERTF3570 (Rohm Semiconductor) is discontinued at DiGi Electronics and should not be selected for new designs despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute RMCF0805FT357R with any of the listed parts?

A: Yes, all listed parts meet the core electrical and mechanical specifications (357 Ω ±1%, 0.125W, 0805 package, ±100ppm/°C, -55°C to 155°C operating range, ROHS3 compliance, MSL 1). Physical height variations (0.50mm to 0.70mm) fall within standard PCB assembly tolerances and do not affect substitutability.

Q: Does the absence of AEC-Q200 rating on some parts affect substitution?

A: AEC-Q200 is an automotive qualification standard. If your application requires automotive-grade components, select only from parts explicitly rated AEC-Q200: CRCW0805357RFKEA, ERJ-6ENF3570V, or KTR10EZPF3570. For non-automotive applications, parts without AEC-Q200 rating are fully substitutable.

Q: Why is MCR10ERTF3570 listed if it is discontinued?

A: MCR10ERTF3570 is included for reference in existing designs currently using this part. For new designs, select from active production alternatives. Existing inventory (2,861 pcs) may support near-term requirements, but long-term supply cannot be guaranteed.

Q: What is the significance of "High Voltage" feature on KTR10EZPF3570?

A: The high voltage capability is an additional feature beyond the base specification. It does not change the core electrical parameters (357 Ω ±1%, 0.125W) but provides enhanced performance margin in applications subject to transient overvoltage conditions. This part remains fully substitutable for standard applications.

Q: Are there differences in moisture resistance between these parts?

A: RC0805FR-07357RL and ERJ-6ENF3570V are explicitly rated for moisture resistance. All parts maintain MSL 1 (Unlimited) rating, indicating they do not require special moisture control during storage or handling. Moisture-resistant construction provides additional protection in high-humidity environments but is not required for standard applications.

Q: How do I verify compatibility with my PCB design?

A: Confirm that your PCB footprint accommodates the 0805 (2012 Metric) package dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm). Verify that your assembly process can accommodate the maximum seated height of the selected part (range: 0.50mm to 0.70mm). All listed parts are compatible with standard 0805 PCB footprints.
