Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F52R3CS is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitutability:

Electrical Parameters:

• Resistance value: 52.3 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All identified substitute parts meet these criteria. Additional features such as automotive AEC-Q200 qualification represent enhanced specifications that do not preclude substitution but indicate expanded application scope.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are functionally equivalent to the RC2012F52R3CS and are suitable for direct replacement in applications where the original part is specified. Selection among equivalent parts is based on the following factors:

Availability and Lead Time: The ERJ-6ENF52R3V (Panasonic) offers the highest inventory level at 45,799 pieces, followed by CRCW080552R3FKEA (Vishay Dale) at 8,015 pieces. The RC0805FR-0752R3L (YAGEO) provides 1,143 pieces, and RMCF0805FT52R3 (Stackpole) offers 3,616 pieces. The original RC2012F52R3CS (Samsung) maintains 794 pieces in stock.

Compliance and Certifications: All parts maintain ROHS3 compliance and REACH Unaffected status. The CRCW080552R3FKEA, ERJ-6ENF52R3V, and RMCF0805FT52R3 include automotive AEC-Q200 qualification, which extends application scope to automotive environments while maintaining full compatibility with general-purpose applications.

Physical Dimensions: All parts conform to 0805 (2012 Metric) package specifications. Height variations are minimal and within standard PCB assembly tolerances: RC2012F52R3CS (0.66mm), RC0805FR-0752R3L (0.60mm), CRCW080552R3FKEA (0.50mm), ERJ-6ENF52R3V (0.70mm), and RMCF0805FT52R3 (0.65mm).

Frequently Asked Questions (FAQ)

Q: Can the RC0805FR-0752R3L (YAGEO) be used as a direct replacement for the RC2012F52R3CS (Samsung)?

A: Yes. The RC0805FR-0752R3L meets all electrical and mechanical specifications of the RC2012F52R3CS, including resistance value, tolerance, power rating, package format, temperature range, and compliance certifications. Direct substitution is supported.

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

A: The CRCW080552R3FKEA (Vishay Dale), ERJ-6ENF52R3V (Panasonic), and RMCF0805FT52R3 (Stackpole) include automotive AEC-Q200 qualification. This certification indicates compliance with automotive reliability and quality standards. These parts are suitable for both general-purpose and automotive applications. The RC2012F52R3CS and RC0805FR-0752R3L do not carry AEC-Q200 qualification but remain fully compatible for non-automotive applications.

Q: Are there any physical compatibility issues when substituting these parts on existing PCBs?

A: No. All substitute parts use the identical 0805 (2012 Metric) package format with two terminations. Height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances and do not affect placement or soldering processes.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the original RC2012F52R3CS, carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which substitute part offers the best availability?

A: The ERJ-6ENF52R3V (Panasonic Electronic Components) offers the highest inventory level at 45,799 pieces, providing optimal availability for high-volume procurement requirements.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed, including the RC2012F52R3CS and all substitute options, maintain ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.
