• Identical resistance value: 412 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.125W (1/8W)
• Same package footprint: 0805 (2012 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• RoHS3 compliance requirement

All identified substitutes meet these core electrical and mechanical parameters, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are Active status components with RoHS3 compliance, matching the original RMCS0805FT412R specification.

CRCW0805412RFKEA (Vishay Dale) carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards.

ERJ-6ENF4120V (Panasonic Electronic Components) also features AEC-Q200 automotive qualification and is available in Cut Tape and Digi-Reel packaging options.

RC0805FR-07412RL (YAGEO) incorporates moisture-resistant construction and is supplied in Tape & Reel packaging.

Selection among these substitutes depends on specific application requirements regarding automotive qualification, packaging format, and environmental protection features.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805412RFKEA replace RMCS0805FT412R directly?

A: Yes. Both components share identical electrical specifications (412 Ohms ±1%, 0.125W), matching temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and 0805 package footprint. The primary difference is CRCW0805412RFKEA includes AEC-Q200 automotive qualification and has a maximum seated height of 0.020" versus 0.024" for the original part.

Q: What is the difference between ERJ-6ENF4120V and RC0805FR-07412RL?

A: Both parts meet the core electrical and mechanical requirements. ERJ-6ENF4120V features AEC-Q200 automotive qualification and has a maximum seated height of 0.028". RC0805FR-07412RL incorporates moisture-resistant construction with a maximum seated height of 0.024". Packaging differs: ERJ-6ENF4120V is available in Cut Tape and Digi-Reel format, while RC0805FR-07412RL is supplied in Tape & Reel.

Q: Are all substitutes RoHS3 compliant?

A: Yes. RMCS0805FT412R, CRCW0805412RFKEA, ERJ-6ENF4120V, and RC0805FR-07412RL are all RoHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Does seated height variation affect PCB assembly?

A: Seated height differences (0.020" to 0.028") are within standard 0805 package tolerances and do not affect PCB assembly compatibility. All parts maintain the same 0.079" x 0.049" footprint dimensions.

Q: Which substitute offers the best availability?

A: RC0805FR-07412RL (YAGEO) shows the highest inventory level at 121,312 pieces, followed by ERJ-6ENF4120V (Panasonic) at 105,380 pieces, and CRCW0805412RFKEA (Vishay Dale) at 34,956 pieces.
