Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F5493CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Resistance value (549 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package designation (0805 / 2012 Metric), composition (Thick Film), and number of terminations (2) must match exactly.

Compliance Parameters: RoHS3 compliance and MSL 1 rating are maintained across all qualified substitutes.

All substitute parts listed meet these criteria. Additional certifications such as Automotive AEC-Q200 represent enhanced qualification levels and do not disqualify parts from substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are qualified equivalents for direct replacement of the RC2012F5493CS based on electrical and mechanical parameter equivalence. Selection among these alternatives is determined by availability, lead time, and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07549KL replace RC2012F5493CS in all applications?

A: Yes. RC0805FR-07549KL is a direct electrical and mechanical equivalent. Both components share identical resistance (549 kOhms), tolerance (±1%), power rating (0.125W), package format (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: The RC2012F5493CS features moisture-resistant thick film composition. Substitute parts CRCW0805549KFKEA, ERJ-6ENF5493V, and RMCF0805FT549K include Automotive AEC-Q200 certification in addition to moisture resistance. AEC-Q200 represents enhanced qualification for automotive applications. Both feature sets are compatible for substitution in non-automotive applications.

Q: Are there height differences between substitute parts?

A: Yes. Seated heights vary: RC2012F5493CS (0.66mm), RC0805FR-07549KL (0.60mm), CRCW0805549KFKEA (0.50mm), ERJ-6ENF5493V (0.70mm), and RMCF0805FT549K (0.65mm). All variations remain within 0805 package specifications. Height differences are relevant only for applications with strict PCB clearance constraints.

Q: Which substitute has the best inventory availability?

A: ERJ-6ENF5493V (Panasonic) offers the highest inventory with 40,629 pieces in stock, followed by CRCW0805549KFKEA (Vishay Dale) with 20,387 pieces and RC0805FR-07549KL (YAGEO) with 18,708 pieces.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts conform to 0805 (2012 Metric) package specifications with identical footprints, termination count (2), and electrical characteristics. PCB design files and assembly processes require no modification for substitution.

Q: What compliance certifications apply to all parts?

A: All parts maintain ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, REACH Unaffected status, and EAR99 export classification. HTSUS code 8533.21.0030 applies uniformly across all variants.
