Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F5490CS are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match Exactly):

• Resistance: 549 Ohms
• Tolerance: ±1%
• Power Rating: 0.125W (1/8W)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0805 (2012 Metric)
• Number of Terminations: 2
• Composition: Thick Film
• Moisture Resistance: Required

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Packaging: Tape & Reel (TR)

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification represent enhanced qualifications that do not disqualify parts from substitution but indicate upgraded performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are qualified direct replacements for the RC2012F5490CS based on matching electrical specifications, mechanical dimensions, and compliance certifications.

Direct Equivalent (Recommended for Standard Applications): RC0805FR-07549RL (YAGEO) provides direct functional equivalence with identical electrical parameters and moisture resistance features. This part maintains the same performance characteristics as the original Samsung component.

Upgraded Alternatives (Recommended for Automotive and Enhanced Reliability Applications): AC0805FR-07549RL (YAGEO), CRCW0805549RFKEA (Vishay Dale), ERJ-6ENF5490V (Panasonic), and RMCF0805FT549R (Stackpole) all include Automotive AEC-Q200 certification in addition to meeting base electrical and mechanical requirements. These parts are suitable for applications requiring automotive-grade qualification or enhanced reliability standards.

Selection Considerations:

• All parts maintain ROHS3 compliance and MSL 1 rating
• Height variations (0.020" to 0.028") are within typical PCB assembly tolerances for 0805 packages
• Inventory availability varies across manufacturers; select based on supply chain requirements
• All parts are Active product status with established manufacturing support

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07549RL replace RC2012F5490CS directly without design changes?

A: Yes. RC0805FR-07549RL meets all electrical and mechanical parameters of the original part. Both components share identical resistance value (549 Ohms), tolerance (±1%), power rating (0.125W), package format (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Moisture resistance and RoHS3 compliance are equivalent.

Q: What is the difference between standard and AEC-Q200 qualified versions?

A: AC0805FR-07549RL, CRCW0805549RFKEA, ERJ-6ENF5490V, and RMCF0805FT549R include Automotive AEC-Q200 certification, indicating compliance with automotive industry reliability and qualification standards. These parts are functionally equivalent to the standard RC2012F5490CS but carry additional automotive-grade qualifications. Selection depends on application requirements.

Q: Are there height differences between substitute parts?

A: Yes. Seated height varies from 0.020" (0.50mm) to 0.028" (0.70mm) across the substitute options. The original RC2012F5490CS has a maximum seated height of 0.026" (0.66mm). These variations are within standard PCB assembly tolerances for 0805 packages and do not affect electrical performance or PCB layout compatibility.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All listed substitute parts carry MSL 1 (Unlimited) rating, identical to the original RC2012F5490CS. This indicates no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Which substitute part has the highest inventory availability?

A: ERJ-6ENF5490V (Panasonic) has the highest inventory with 81,492 pieces in stock, followed by RMCF0805FT549R (Stackpole) with 38,114 pieces. RC0805FR-07549RL (YAGEO) has 24,858 pieces available.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 Compliant, matching the compliance status of the original RC2012F5490CS.
