Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F8453CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 845 kOhms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical.

Package Compatibility: All substitute parts must use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm).

Thermal Specifications: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C ~ 155°C must match.

Composition and Construction: Thick film construction is required for all substitutes.

Compliance Requirements: RoHS3 compliance and MSL Level 1 (Unlimited) are mandatory. REACH Unaffected status applies to all qualified substitutes.

Packaging Format: Tape & Reel (TR) packaging is standard across all listed alternatives.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the RCS2012F8453CS. Selection among alternatives is based on the following factors:

Compliance Certifications: CRCW0805845KFKEA, ERJ-6ENF8453V, and RMCF0805FT845K carry AEC-Q200 automotive qualification. RC0805FR-07845KL and RCS2012F8453CS do not include automotive certification but maintain standard industrial compliance.

Product Availability: All substitute parts maintain Active product status with current manufacturing support.

RoHS and Environmental Compliance: All parts are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements.

Moisture Sensitivity: All parts are classified as MSL Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Physical Dimensions: Height variations exist among substitutes (0.020" to 0.028" seated height). Component selection should account for PCB assembly clearance requirements and reflow profile compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805845KFKEA replace RCS2012F8453CS in non-automotive applications?

A: Yes. CRCW0805845KFKEA meets all electrical and mechanical specifications required for RCS2012F8453CS replacement. AEC-Q200 certification is an additional qualification that does not restrict use in standard industrial applications.

Q: Are there differences in moisture resistance between the main part and substitutes?

A: RCS2012F8453CS specifies anti-sulfur and moisture-resistant features. RC0805FR-07845KL also specifies moisture-resistant construction. CRCW0805845KFKEA, ERJ-6ENF8453V, and RMCF0805FT845K do not explicitly list these features in their descriptions, though all parts maintain MSL Level 1 classification.

Q: Do seated height differences affect PCB assembly compatibility?

A: Seated height variations range from 0.020" (0.50mm) to 0.028" (0.70mm). These differences are within typical PCB assembly tolerances and do not affect electrical performance. Verify clearance requirements for specific PCB designs with restricted component height specifications.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, matching the packaging specification of RCS2012F8453CS.

Q: What is the significance of the ±100ppm/°C temperature coefficient across all parts?

A: The temperature coefficient specifies resistance change per degree Celsius within the operating temperature range of -55°C to 155°C. All parts share identical temperature coefficient specifications, ensuring equivalent thermal performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. All substitute parts maintain identical electrical specifications (845 kOhms ±1% at 0.125W), package dimensions (0805 / 2012 Metric), and compliance certifications. Direct substitution is supported without design modification.
