Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F4023CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 402 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these mandatory parameters. Variations in physical height (seated maximum) and specific feature sets (such as automotive AEC-Q200 qualification or high-voltage capability) do not disqualify substitution, as these represent enhanced or application-specific characteristics that remain compatible with the base electrical specification.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RCS2012F4023CS based on matching resistance, tolerance, power rating, package type, temperature coefficient, and operating temperature range.

Selection Considerations Based on Product Status and Compliance:

• CRCW0805402KFKEA (Vishay Dale): Active status. Automotive AEC-Q200 qualified. Lowest seated height (0.50mm) provides design flexibility for space-constrained applications.

• ERJ-6ENF4023V (Panasonic Electronic Components): Active status. Automotive AEC-Q200 qualified. Highest seated height (0.70mm) among substitutes.

• KTR10EZPF4023 (Rohm Semiconductor): Active status. Automotive AEC-Q200 qualified with high-voltage capability. Seated height 0.65mm.

• RC0805FR-07402KL (YAGEO): Active status. Moisture-resistant feature aligns with original part characteristics. Seated height 0.60mm.

• RMCF0805FT402K (Stackpole Electronics Inc): Active status. Automotive AEC-Q200 qualified. Seated height 0.65mm. Highest inventory availability (45,874 pcs).

All substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) rating, matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805402KFKEA replace RCS2012F4023CS in non-automotive applications?

A: Yes. The CRCW0805402KFKEA meets all mandatory electrical parameters (402 kOhms ±1%, 0.125W, 0805 package, ±100ppm/°C, -55°C ~ 155°C). Automotive AEC-Q200 qualification is an additional feature that does not restrict use in general-purpose applications.

Q: What is the significance of the seated height differences shown in the parameter comparison?

A: Seated height variations (0.50mm to 0.70mm) reflect manufacturing tolerances and design differences between manufacturers. All values remain within acceptable limits for 0805 package specifications. Height differences are relevant only for applications with strict vertical clearance constraints or automated assembly processes with height-sensitive placement equipment.

Q: Are all substitute parts suitable for high-temperature applications?

A: Yes. All substitute parts and the original RCS2012F4023CS share the same operating temperature range of -55°C ~ 155°C and identical temperature coefficient of ±100ppm/°C.

Q: Does the "High Voltage" feature of KTR10EZPF4023 indicate superior performance?

A: The high-voltage designation indicates enhanced capability for high-voltage circuit applications. This feature does not affect substitution eligibility for standard applications. Selection should be based on circuit requirements rather than feature presence.

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

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life without special moisture control measures. All listed parts, including the original RCS2012F4023CS, carry this rating, ensuring equivalent handling and storage requirements.

Q: Can substitute parts be mixed within a single assembly?

A: Yes. All substitute parts meet identical electrical specifications and package dimensions. Mixed sourcing is permissible from an engineering standpoint, though procurement and quality control procedures should address traceability and documentation requirements.
