Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F2491CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are: (1) identical resistance value of 2.49 kOhms, (2) matching tolerance of ±1%, (3) compatible power rating of 0.125W, (4) identical 0805 package format, (5) matching temperature coefficient of ±100ppm/°C, and (6) operating temperature range of -55°C to 155°C. All substitute parts maintain two terminations and thick film composition. Secondary considerations include product status (Active), RoHS compliance status, and packaging format (Tape & Reel or Cut Tape). Parts are grouped as Direct Manufacturer Equivalents, Upgrade variants with enhanced ratings, and Similar alternatives from different manufacturers that meet all core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for Standard Applications): RC0805FR-072K49L (YAGEO) provides direct functional equivalence with identical electrical specifications and RoHS3 compliance. This part maintains the same 0.125W power rating and moisture resistance features as the original RC2012F2491CS, with superior inventory availability (25,400 pieces).

Upgrade Option (Automotive-Qualified Applications): AC0805FR-072K49L (YAGEO) offers automotive AEC-Q200 qualification while maintaining all core electrical parameters. This upgrade is suitable for applications requiring automotive-grade reliability and environmental stress screening.

High-Inventory Alternatives: RMCF0805FT2K49 (Stackpole Electronics Inc) and ERJ-6ENF2491V (Panasonic Electronic Components) both provide AEC-Q200 automotive qualification with significantly higher inventory levels (135,998 and 135,274 pieces respectively), ensuring supply chain continuity for high-volume production.

Higher Power Rating Options: CRCW08052K49FKEAHP (Vishay Dale) and RCS08052K49FKEA (Vishay Dale) feature 0.5W power rating with pulse withstanding capability, suitable for applications requiring enhanced power dissipation or transient protection. These parts maintain AEC-Q200 qualification and RoHS3 compliance.

Compliance Consideration: CRCW08052K49FKTA (Vishay Dale) is RoHS non-compliant and REACH-affected; selection of this part requires explicit compliance verification for target applications and markets.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-072K49L directly replace RC2012F2491CS without circuit modification? A: Yes. RC0805FR-072K49L matches all critical electrical parameters (2.49 kΩ ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (0805 package, 2 terminations). Physical height difference (0.60mm vs 0.66mm) is within standard PCB assembly tolerances.

Q: What is the difference between standard and AEC-Q200 qualified parts? A: AEC-Q200 qualified parts (AC0805FR-072K49L, CRCW08052K49FKEA, ERJ-6ENF2491V, RCS08052K49FKEA, RMCF0805FT2K49) undergo automotive-grade environmental stress screening and reliability testing. These parts are required for automotive and mission-critical applications. The RC2012F2491CS and RC0805FR-072K49L lack this qualification.

Q: Are higher power rating parts (0.5W) compatible substitutes? A: CRCW08052K49FKEAHP and RCS08052K49FKEA (0.5W rating) are electrically compatible but represent design upgrades. Higher power rating provides additional thermal margin and pulse withstanding capability. These parts are physically compatible in 0805 footprints but should be selected only when enhanced power handling is required or specified.

Q: What packaging format differences exist among substitutes? A: Most substitutes are supplied in Tape & Reel (TR) format matching the original RC2012F2491CS. CRCW08052K49FKTA is available in Cut Tape (CT) & Digi-Reel® format, suitable for lower-volume or manual assembly operations. Packaging format does not affect electrical or mechanical compatibility.

Q: Why do some parts show different RoHS compliance status? A: CRCW08052K49FKTA is RoHS non-compliant and REACH-affected due to manufacturing process or material composition. For applications requiring RoHS3 compliance (EU, China, and other regulated markets), select parts explicitly marked as RoHS3 Compliant: RC0805FR-072K49L, AC0805FR-072K49L, CRCW08052K49FKEA, ERJ-6ENF2491V, RCS08052K49FKEA, or RMCF0805FT2K49.

Q: Which substitute offers the best inventory availability? A: RMCF0805FT2K49 (Stackpole Electronics Inc) provides the highest inventory level at 135,998 pieces, followed by ERJ-6ENF2491V (Panasonic) at 135,274 pieces. Both parts include AEC-Q200 automotive qualification and RoHS3 compliance.

Q: Can I use these parts interchangeably in existing designs? A: Yes, all listed substitutes are mechanically and electrically interchangeable within the 0805 package footprint. Physical height variations (0.50mm to 0.70mm) are within standard PCB assembly specifications. No circuit design changes are required for direct substitution.
