RC2012F2493CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F2493CS is a 249 kOhms ±1% 0.125W thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This component is classified as Active product status with moisture resistant characteristics and ROHS3 compliance. Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical dimensions (0805 package), and material composition (thick film). Alternative sources become necessary for supply chain continuity, regional availability, or specific application requirements such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• Resistance Value: 249 kOhms
• Tolerance: ±1%
• Power Rating: 0.125W (1/8W)
• Package / Case: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

Compliance Considerations: Parts are grouped into two categories based on regulatory status:

• Direct Equivalents: ROHS3 Compliant, REACH Unaffected status matching the main part
• Similar Parts: May include automotive AEC-Q200 qualification, alternative compliance profiles, or enhanced power ratings (0.5W) that exceed base specifications

Parts with differing power ratings (0.5W instead of 0.125W) or non-compliant regulatory status are classified as similar rather than direct equivalents, as they introduce design changes or compliance considerations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (ROHS3 Compliant, REACH Unaffected):

The following parts maintain full electrical and mechanical equivalence with identical compliance profiles:

• CR0805-FX-2493ELF (Bourns Inc.): Direct substitute with moisture resistant composition. Tape & Reel packaging. Height 0.60mm.
• RC0805FR-07249KL (YAGEO): Direct substitute with moisture resistant composition. Cut Tape & Digi-Reel packaging. Height 0.60mm. Highest inventory availability (428,913 pcs).
• CRCW0805249KFKECC (Vishay Dale): Direct substitute with standard thick film composition. Tape & Reel packaging. Height 0.60mm. Large inventory (150,762 pcs).

Automotive-Qualified Alternatives (ROHS3 Compliant, AEC-Q200 Rated):

For applications requiring automotive qualification:

• ERJ-6ENF2493V (Panasonic Electronic Components): AEC-Q200 qualified. Cut Tape & Digi-Reel packaging. Height 0.70mm. High inventory (86,828 pcs).
• RMCF0805FT249K (Stackpole Electronics Inc): AEC-Q200 qualified. Tape & Reel packaging. Height 0.65mm. Inventory 43,483 pcs.
• CRCW0805249KFKEA (Vishay Dale): AEC-Q200 qualified. Tape & Reel packaging. Height 0.50mm. Inventory 31,346 pcs.
• KTR10EZPF2493 (Rohm Semiconductor): AEC-Q200 qualified with high voltage capability. Tape & Reel packaging. Height 0.65mm. Limited inventory (848 pcs).

Non-Compliant Status (Not Recommended for New Designs):

• CRCW0805249KFKTA (Vishay Dale): RoHS non-compliant and REACH affected. Suitable only for legacy system maintenance where compliance exemptions apply.

Enhanced Power Rating Options (0.5W, 1/2W):

These parts exceed the base 0.125W specification and introduce design changes:

• CRCW0805249KFKEAHP (Vishay Dale): 0.5W rating with pulse withstanding capability. AEC-Q200 qualified. Height 0.50mm. Inventory 7,150 pcs.
• RCS0805249KFKEA (Vishay Dale): 0.5W rating with pulse withstanding capability. AEC-Q200 qualified. Height 0.50mm. Inventory 2,511 pcs.

Frequently Asked Questions (FAQ)

Q1: Can I substitute RC2012F2493CS with any 249 kOhm 0805 resistor?

A: No. Substitution requires matching all critical parameters: 249 kOhms resistance, ±1% tolerance, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Parts with different power ratings (0.5W) or composition types are not direct equivalents.

Q2: What is the difference between direct equivalents and automotive-qualified alternatives?

A: Direct equivalents (CR0805-FX-2493ELF, RC0805FR-07249KL, CRCW0805249KFKECC) maintain identical specifications and compliance status. Automotive-qualified alternatives (ERJ-6ENF2493V, RMCF0805FT249K, CRCW0805249KFKEA, KTR10EZPF2493) add AEC-Q200 certification for automotive applications but are electrically equivalent. Selection depends on application requirements.

Q3: Why do some substitutes have different maximum heights?

A: Height variation (0.50mm to 0.70mm) reflects manufacturing tolerances across different manufacturers. All parts meet the 0805 package specification. Height differences may affect PCB layout clearance in space-constrained designs. Verify mechanical fit in your specific application.

Q4: Is CRCW0805249KFKTA suitable for new designs?

A: No. This part is RoHS non-compliant and REACH affected. It is restricted for new product development in most markets. Use only for legacy system maintenance where regulatory exemptions apply.

Q5: What packaging options are available?

A: Substitutes are supplied in three packaging formats: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel, or unspecified packaging. Tape & Reel is standard for high-volume production. Cut Tape & Digi-Reel suits lower-volume or mixed-component orders. Verify packaging compatibility with your assembly process.

Q6: Can I use 0.5W rated parts as substitutes for 0.125W applications?

A: Electrically, yes. Parts rated 0.5W (CRCW0805249KFKEAHP, RCS0805249KFKEA) are over-specified for 0.125W circuits and will operate safely. However, they are not direct equivalents and introduce design changes. Use only if your design review approves the higher power rating and associated cost increase.

Q7: Which substitute has the highest inventory availability?

A: RC0805FR-07249KL (YAGEO) with 428,913 pcs in stock. This part is a direct equivalent with moisture resistant composition and ROHS3 compliance, making it suitable for immediate procurement needs.

Q8: Are all listed substitutes ROHS3 compliant?

A: No. CRCW0805249KFKTA is RoHS non-compliant. All other direct and automotive-qualified alternatives are ROHS3 compliant. Verify compliance requirements for your target market before selection.
