Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F5233CS is determined by strict equivalence across the following parameters:

Electrical Specifications:

• Resistance value: 523 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Specifications:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance & Environmental:

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these core parameters. Variations in height (seated maximum) and specific feature sets (anti-sulfur vs. automotive AEC-Q200 certification) do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F5233CS based on electrical and mechanical parameter alignment. Selection among these alternatives is determined by application-specific requirements and compliance certifications:

CRCW0805523KFKEA (Vishay Dale): Automotive AEC-Q200 rated. Suitable for automotive and high-reliability applications requiring automotive-grade qualification. Lowest seated height (0.020").

ERJ-6ENF5233V (Panasonic Electronic Components): Automotive AEC-Q200 rated. Suitable for automotive and high-reliability applications. Highest seated height (0.028").

RC0805FR-07523KL (YAGEO): Moisture-resistant construction without automotive certification. Suitable for general industrial and consumer applications. Mid-range seated height (0.024").

RMCF0805FT523K (Stackpole Electronics Inc): Automotive AEC-Q200 rated. Suitable for automotive and high-reliability applications. Seated height (0.026") matches the original RCS2012F5233CS.

All parts maintain ROHS3 compliance and REACH unaffected status. Selection should account for application environment, supply chain availability, and any specific automotive or industrial qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805523KFKEA replace RCS2012F5233CS in any application?

A: Yes. Both components share identical electrical specifications (523 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), identical package dimensions (0805 / 2012 Metric), and equivalent compliance certifications (ROHS3, REACH Unaffected, MSL 1). The CRCW0805523KFKEA features automotive AEC-Q200 certification, which provides additional qualification for automotive applications.

Q: What is the difference between anti-sulfur and automotive AEC-Q200 features?

A: Anti-sulfur construction protects against sulfur-induced corrosion in specific environmental conditions. Automotive AEC-Q200 certification indicates the component meets automotive industry reliability and qualification standards. These are distinct feature sets; neither supersedes the other. Selection depends on application environment and regulatory requirements.

Q: Are the height differences between substitute parts significant?

A: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm). These differences are within typical PCB assembly tolerances for 0805 components. Height becomes relevant only in space-constrained applications or when specific clearance requirements exist. For standard applications, height variation is not a substitution barrier.

Q: Can I use ERJ-6ENF5233V in place of RCS2012F5233CS in a consumer electronics application?

A: Yes. Both components meet the same electrical and mechanical specifications. The ERJ-6ENF5233V includes automotive AEC-Q200 certification, which exceeds consumer application requirements. This substitution is valid and may provide enhanced reliability margins.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts, including the original RCS2012F5233CS and all substitutes, carry MSL 1 rating, eliminating moisture-related handling constraints.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel packaging, matching the original RCS2012F5233CS packaging format for automated assembly compatibility.

Q: Which substitute part most closely matches the original RCS2012F5233CS specifications?

A: RMCF0805FT523K (Stackpole Electronics Inc) provides the closest match, with seated height of 0.026" (0.65mm) compared to the original 0.026" (0.66mm). RC0805FR-07523KL (YAGEO) offers the most extensive inventory availability at 50,957 pieces.
