Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012F46R4CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 46.4 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Specifications:

• Package format: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance & Environmental:

• RoHS3 compliance
• REACH unaffected status
• Moisture Sensitivity Level 1

All identified substitute parts maintain these specifications. Substitute parts are grouped into two categories: direct equivalents (identical specifications including height) and similar parts (identical electrical and mechanical specifications with minor height variations or additional certifications such as AEC-Q200 automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RC2012F46R4CS. Selection among these alternatives is based on the following factors:

Direct Equivalent: The RC0805FR-0746R4L from YAGEO is a direct equivalent offering identical specifications with no additional certifications. This part is suitable for general-purpose applications where standard RoHS3 compliance is the only requirement.

Automotive-Qualified Alternatives: The CRCW080546R4FKEA (Vishay Dale), ERJ-6ENF46R4V (Panasonic), and RMCF0805FT46R4 (Stackpole) all carry AEC-Q200 automotive qualification in addition to standard RoHS3 compliance. These parts are appropriate for applications requiring automotive-grade reliability and traceability. The AEC-Q200 rating does not restrict use in non-automotive applications.

Inventory Availability: Part availability varies across manufacturers. Selection may be influenced by supply chain considerations and lead time requirements specific to procurement timelines.

Height Considerations: All substitute parts operate within the 0805 package specification. Height variations range from 0.020" to 0.028" (0.50mm to 0.70mm). These minor differences are within standard PCB assembly tolerances and do not affect functional performance or board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0746R4L be used as a direct replacement for RC2012F46R4CS?

A: Yes. The RC0805FR-0746R4L maintains identical electrical specifications (46.4 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (0805 package, 2.00mm x 1.25mm dimensions). Both parts are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the Samsung part and the automotive-qualified alternatives?

A: The Samsung RC2012F46R4CS is a standard industrial-grade thick film resistor. The CRCW080546R4FKEA, ERJ-6ENF46R4V, and RMCF0805FT46R4 carry AEC-Q200 automotive qualification, indicating compliance with automotive reliability and qualification standards. All parts share identical electrical and mechanical specifications.

Q: Are there any height restrictions when substituting these parts?

A: All substitute parts conform to the 0805 (2012 Metric) package standard. Height variations (0.020" to 0.028") are within standard PCB assembly tolerances and do not create compatibility issues. Component placement and soldering processes remain unchanged.

Q: Can these parts be used interchangeably in production?

A: Yes, all identified substitute parts are electrically and mechanically interchangeable with the RC2012F46R4CS. Substitution does not require circuit redesign, PCB layout modification, or assembly process changes. All parts are supplied in Tape & Reel packaging format.

Q: What compliance certifications apply to all substitute parts?

A: All parts listed are RoHS3 compliant and REACH unaffected. The automotive-qualified alternatives (Vishay Dale, Panasonic, Stackpole) additionally carry AEC-Q200 certification. Moisture Sensitivity Level 1 applies uniformly across all parts, indicating unlimited shelf life under standard storage conditions.

Q: How do temperature coefficients affect part selection?

A: All substitute parts maintain the same temperature coefficient specification of ±100ppm/°C and identical operating temperature range of -55°C to 155°C. Temperature performance is equivalent across all alternatives.
