• Identical resistance value: 22.6 Ohms
• Matching tolerance: ±1%
• Equivalent power rating: 0.25W (1/4W)
• Same package designation: 1206 (3216 Metric)
• Identical composition: Thick Film
• Matching temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

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 meet the core electrical and mechanical specifications of the RMCS1206FT22R6. Selection should be based on product status and application requirements:

CRCW120622R6FKEA (Vishay Dale) is recommended for new designs requiring automotive-grade components. This part carries AEC-Q200 qualification and maintains active production status, making it suitable for long-term supply chain stability.

RC1206FR-0722R6L (YAGEO) is suitable for applications requiring moisture-resistant thick film construction. This part is in active production and provides equivalent electrical performance with moisture resistance features.

ERJ-8ENF22R6V (Panasonic) carries AEC-Q200 automotive qualification but is designated as "Not For New Designs." This part should be used only in legacy system maintenance or where existing design documentation specifies this component.

Frequently Asked Questions (FAQ)

Q: Can CRCW120622R6FKEA directly replace RMCS1206FT22R6?

A: Yes. Both parts share identical electrical specifications (22.6 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C to 155°C), and use the same 1206 package. Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What is the difference between the automotive-qualified substitutes and the standard part?

A: CRCW120622R6FKEA and ERJ-8ENF22R6V carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards. The RMCS1206FT22R6 and RC1206FR-0722R6L do not carry this designation. Selection depends on application requirements.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within acceptable tolerances. RMCS1206FT22R6 and RC1206FR-0722R6L have maximum seated heights of 0.026" (0.65mm), while CRCW120622R6FKEA and ERJ-8ENF22R6V have maximum seated heights of 0.024" (0.60mm) and 0.028" (0.70mm) respectively. These variations do not affect PCB assembly compatibility for standard 1206 footprints.

Q: Why is ERJ-8ENF22R6V marked "Not For New Designs"?

A: This designation indicates the manufacturer is phasing out this product line. While the part remains functionally equivalent and available in inventory, it should not be selected for new product development to ensure long-term supply chain continuity.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
