Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F5490CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 549 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Parameters (Must Match):

• RoHS3 Compliant
• MSL 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these mandatory criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), height tolerances within the 1206 specification, and optional automotive certifications do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The CRCW1206549RFKEA (Vishay Dale) and RC1206FR-07549RL (YAGEO) are recommended as primary substitutes. Both parts maintain Active product status, ensuring long-term availability and continued manufacturer support. The CRCW1206549RFKEA includes automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. The RC1206FR-07549RL provides moisture-resistant characteristics aligned with the original RCS3216F5490CS specification.

Secondary Selection (Legacy Status): The ERJ-8ENF5490V (Panasonic) is functionally equivalent but carries a "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies where the original part number is unavailable. New circuit designs should not incorporate this part number.

Compliance Verification: All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original part's environmental and regulatory compliance profile.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206549RFKEA replace RCS3216F5490CS in any application? A: Yes. Both parts share identical electrical specifications (549 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package dimensions. The primary difference is packaging format (Tape & Reel vs. bulk) and optional automotive certification on the Vishay part. Functional substitution is direct.

Q: What is the significance of the "Not For New Designs" status on ERJ-8ENF5490V? A: This designation indicates that Panasonic has discontinued active development and marketing of this part number. While the part remains functionally equivalent and available in stock, it should only be used for repair or replacement of existing assemblies. New circuit designs must select from parts with Active status.

Q: Are there dimensional differences between substitute parts? A: All parts conform to the 1206 (3216 Metric) package specification. Height variations (0.024" to 0.028" seated maximum) fall within standard 1206 tolerances and do not affect PCB assembly compatibility or circuit performance.

Q: Does the automotive AEC-Q200 certification on CRCW1206549RFKEA affect non-automotive applications? A: No. AEC-Q200 certification represents an additional qualification level and does not restrict use in non-automotive applications. The part is fully compatible with all applications requiring 549 Ohm ±1% 0.25W resistors.

Q: What packaging formats are available for these substitute parts? A: RCS3216F5490CS is supplied in bulk. CRCW1206549RFKEA and ERJ-8ENF5490V are supplied in Tape & Reel format. RC1206FR-07549RL is available in Cut Tape and Digi-Reel format. Packaging selection depends on assembly process requirements and volume specifications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All identified substitute parts carry ROHS3 Compliant status and are REACH unaffected, matching the environmental compliance profile of the original RCS3216F5490CS.
