Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F435CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 4.3 MOhms
• 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
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

All identified substitute parts meet these mandatory parameters. Variations in physical dimensions (Height - Seated) and specific feature sets (such as Automotive AEC-Q200 or High Voltage ratings) do not disqualify substitution when core electrical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the RC2012F435CS based on provided specifications. Selection among equivalent parts should be determined by:

Product Status and Availability: All parts are classified as Active product status, ensuring continued manufacturing support and availability.

Compliance Certifications: All substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), matching the original part's regulatory and environmental specifications.

Application-Specific Requirements: The CRCW08054M30FKEA (Vishay Dale) and KTR10EZPF4304 (Rohm) include Automotive AEC-Q200 qualification. These parts are suitable for applications requiring automotive-grade reliability. The KTR10EZPF4304 additionally features High Voltage capability.

Physical Dimensions: Height variations among substitute parts range from 0.020" to 0.026". Verify PCB layout clearance requirements before final selection, particularly in space-constrained designs.

Inventory Considerations: RC0805FR-074M3L (YAGEO) offers the highest inventory availability at 5037 pieces, followed by CRCW08054M30FKEA (Vishay Dale) at 31048 pieces.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-074M3L (YAGEO) be used as a direct replacement for RC2012F435CS (Samsung)?

A: Yes. Both parts share identical electrical specifications: 4.3 MOhms ±1% resistance, 0.125W power rating, thick film composition, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. Both are ROHS3 compliant with MSL 1. Physical height differs by 0.002" (0.06mm), which is negligible for most applications.

Q: What is the difference between CRCW08054M30FKEA and KTR10EZPF4304?

A: Both parts meet all core electrical and mechanical specifications of the RC2012F435CS. CRCW08054M30FKEA is qualified to Automotive AEC-Q200 standard. KTR10EZPF4304 includes both Automotive AEC-Q200 qualification and High Voltage capability. Physical height of CRCW08054M30FKEA is 0.020" (0.50mm), the lowest among all options.

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

A: Yes. All substitute parts, including the original RC2012F435CS, operate across the identical temperature range of -55°C ~ 155°C with ±100ppm/°C temperature coefficient.

Q: Does package size differ among these parts?

A: No. All parts use the 0805 (2012 Metric) package with identical footprint dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). Height variations are minor and do not affect PCB layout compatibility.

Q: Which substitute part has the best inventory availability?

A: CRCW08054M30FKEA (Vishay Dale) has the highest inventory at 31048 pieces. RC0805FR-074M3L (YAGEO) has 5037 pieces available.

Q: Are all parts RoHS compliant?

A: Yes. All parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching regulatory requirements for the original RC2012F435CS.
