Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F8452CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value must be 84.5 kΩ with ±1% tolerance. Temperature coefficient must be ±100ppm/°C. Power rating must be 0.125W (1/8W).

Mechanical & Package Specifications: Package format must be 0805 (2012 Metric). Physical dimensions must be 0.079" L × 0.049" W (2.00mm × 1.25mm). Number of terminations must be 2.

Environmental & Compliance Requirements: Operating temperature range must be -55°C ~ 155°C. Moisture Sensitivity Level must be 1 (Unlimited). RoHS3 compliance is required. REACH Unaffected status applies.

All identified substitute parts meet these criteria. Substitute parts are further categorized by additional features: direct equivalents maintain identical moisture-resistant thick film construction; similar substitutes add automotive AEC-Q200 qualification, which provides enhanced reliability for automotive and high-reliability applications while maintaining full compatibility with standard industrial designs.

Parameter Comparison

Engineering Selection Recommendations

Seated height of 0.024" (0.60mm) is within acceptable tolerance range for 0805 package applications. Suitable for general industrial and commercial circuit designs requiring standard reliability.

CRCW080584K5FKEA (Vishay Dale): Functionally equivalent with additional automotive AEC-Q200 qualification. Provides enhanced reliability certification for automotive-grade applications while maintaining full compatibility with standard designs. Lowest seated height at 0.020" (0.50mm) offers advantage in space-constrained PCB layouts. Appropriate for applications requiring automotive-grade component qualification.

ERJ-6ENF8452V (Panasonic Electronic Components): Functionally equivalent with automotive AEC-Q200 qualification. Seated height of 0.028" (0.70mm) represents maximum height within acceptable tolerance. Suitable for automotive and high-reliability applications. High inventory availability supports supply chain continuity.

RMCF0805FT84K5 (Stackpole Electronics Inc): Functionally equivalent with automotive AEC-Q200 qualification. Seated height of 0.026" (0.65mm) closely matches original part specification. Appropriate for automotive-grade applications requiring enhanced reliability certification.

All substitute parts carry Active product status, full RoHS3 compliance, and REACH Unaffected designation, ensuring regulatory compliance across industrial and commercial markets.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0784K5L replace RC2012F8452CS in any application?

A: Yes. RC0805FR-0784K5L is a direct equivalent meeting all electrical specifications (84.5 kΩ ±1%, 0.125W, ±100ppm/°C), mechanical dimensions (0805 package, 2.00mm × 1.25mm), and environmental requirements (-55°C ~ 155°C, MSL 1, RoHS3 compliant). Seated height difference of 0.002" (0.06mm) is within standard PCB assembly tolerances.

Q: What is the difference between standard and AEC-Q200 qualified substitutes?

A: CRCW080584K5FKEA, ERJ-6ENF8452V, and RMCF0805FT84K5 carry automotive AEC-Q200 qualification, indicating enhanced reliability testing and qualification for automotive applications. All electrical and mechanical parameters remain identical to the original part. AEC-Q200 qualification is not required for standard industrial applications but is mandatory for automotive-grade designs.

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

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging format, matching the original RC2012F8452CS packaging specification.

Q: Does seated height variation affect PCB assembly compatibility?

A: Seated height variations among substitute parts range from 0.020" to 0.028" (0.50mm to 0.70mm), compared to the original 0.026" (0.66mm). These variations fall within standard 0805 package tolerances and do not affect PCB assembly compatibility, solder reflow profiles, or component placement accuracy.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, meeting current environmental and regulatory requirements for industrial and commercial applications.

Q: Can substitute parts be mixed in the same production run?

A: Yes. All substitute parts meet identical electrical specifications, mechanical dimensions, and environmental requirements. Interchangeability is confirmed across all critical parameters. Component sourcing decisions may be based on availability, cost, and supply chain considerations without affecting circuit performance or reliability.
