Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F24R3CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 24.3 Ohms
• 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
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical height (seated maximum), packaging format (Tape & Reel versus Cut Tape), and optional certifications (such as AEC-Q200 automotive qualification) do not preclude substitution but indicate application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

ERJ-6ENF24R3V (Panasonic Electronic Components) and RMCF0805FT24R3 (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain Active product status and include AEC-Q200 automotive qualification, providing enhanced reliability documentation for applications requiring automotive-grade components. These parts are available in Tape & Reel packaging format consistent with high-volume manufacturing processes.

RC0805FR-0724R3L (YAGEO) is an equivalent substitute with Active product status and moisture-resistant construction matching the original RC2012F24R3CS specification. This part offers the lowest seated height (0.024" / 0.60mm) among all substitutes, which may be advantageous for space-constrained PCB layouts.

Secondary Substitute (Discontinued Status):

MCR10ERTF24R3 (Rohm Semiconductor) meets all electrical and mechanical specifications but carries Discontinued at DiGi Electronics product status. This part should be selected only when existing inventory is available and long-term supply continuity is not required. The Cut Tape and Digi-Reel® packaging format differs from standard Tape & Reel, requiring alternative handling procedures.

All substitute parts comply with ROHS3 and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF24R3V replace RC2012F24R3CS in any application?

A: ERJ-6ENF24R3V meets all mandatory electrical and mechanical parameters for direct substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive applications. The seated height difference of 0.002" (0.05mm) is within standard PCB assembly tolerances and does not affect circuit functionality.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging is supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape packaging is supplied in shorter tape segments, typically for manual assembly or lower-volume production. MCR10ERTF24R3 uses Cut Tape format, requiring different handling and feeder compatibility compared to standard Tape & Reel parts.

Q: Why is MCR10ERTF24R3 marked as Discontinued?

A: MCR10ERTF24R3 is discontinued at DiGi Electronics, indicating that this distributor no longer actively stocks or supports this part. However, the part specification remains valid for applications where existing inventory is available. Alternative sources or substitute parts should be evaluated for new designs requiring long-term supply assurance.

Q: Are all substitute parts moisture-resistant?

A: All listed parts maintain MSL 1 (Unlimited) moisture sensitivity rating. RC2012F24R3CS and RC0805FR-0724R3L explicitly specify moisture-resistant construction. ERJ-6ENF24R3V, RMCF0805FT24R3, and MCR10ERTF24R3 achieve equivalent moisture performance through thick film composition and MSL 1 classification, ensuring compatibility with standard storage and assembly conditions.

Q: Can seated height variation affect PCB assembly?

A: Seated height variations among substitute parts range from 0.024" to 0.028" (0.60mm to 0.70mm), representing a maximum difference of 0.004" (0.10mm). This variation is within standard PCB assembly tolerances and does not affect solder joint formation, component placement accuracy, or circuit performance. Height differences become relevant only in applications with strict vertical space constraints or specialized assembly requirements.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts comply with ROHS3 and maintain REACH Unaffected status. ERJ-6ENF24R3V and RMCF0805FT24R3 include AEC-Q200 automotive qualification, providing additional reliability documentation for automotive and high-reliability applications. This certification is optional for general industrial use but indicates enhanced quality assurance processes.
