Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F26R1CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value of 26.1 Ohms, tolerance of ±1%, and power rating of 0.125W (1/8W) must be identical across all substitute parts.

Package Compatibility: All substitute parts must use 0805 (2012 Metric) package format with two terminations to ensure mechanical fit on printed circuit boards designed for the original component.

Environmental Performance: Temperature coefficient of ±100ppm/°C and operating temperature range of -55°C ~ 155°C must be maintained to preserve circuit performance across specified thermal conditions.

Composition and Features: Thick film construction is required. Moisture resistant characteristics are maintained across all qualified substitutes with MSL rating of 1 (Unlimited).

Regulatory Compliance: RoHS3 compliance and REACH unaffected status are mandatory for all substitute parts to meet current environmental and regulatory requirements.

The following four manufacturers provide direct substitutes meeting all specified parameters: YAGEO (RC0805FR-0726R1L), Vishay Dale (CRCW080526R1FKEA), Panasonic Electronic Components (ERJ-6ENF26R1V), and Stackpole Electronics Inc (RMCF0805FT26R1).

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts (RC0805FR-0726R1L, CRCW080526R1FKEA, ERJ-6ENF26R1V, RMCF0805FT26R1) are qualified equivalents to the RC2012F26R1CS based on identical electrical specifications, package format, and regulatory compliance status.

YAGEO RC0805FR-0726R1L provides direct substitution with the lowest seated height (0.024" / 0.60mm) among all options, offering maximum clearance for densely populated circuit boards. This part maintains Active product status with full RoHS3 and REACH compliance.

Vishay Dale CRCW080526R1FKEA includes automotive AEC-Q200 qualification, providing enhanced reliability for applications requiring automotive-grade components. The lowest seated height (0.020" / 0.50mm) supports high-density PCB layouts. This part is available in Cut Tape (CT) & Digi-Reel® packaging in addition to standard Tape & Reel format.

Panasonic Electronic Components ERJ-6ENF26R1V offers automotive AEC-Q200 qualification with the highest seated height (0.028" / 0.70mm) among substitutes. This part maintains the widest thermal margin and is suitable for applications with less stringent height constraints.

Stackpole Electronics Inc RMCF0805FT26R1 provides automotive AEC-Q200 qualification with seated height of 0.026" (0.65mm), matching the original Samsung part height specification. This part is available with lower inventory levels (844 Pcs) compared to other substitutes.

All substitute parts maintain Active product status and full compliance with RoHS3 and REACH regulations, ensuring regulatory continuity in production and supply chain applications.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-0726R1L be used as a direct replacement for RC2012F26R1CS?

A: Yes. RC0805FR-0726R1L manufactured by YAGEO is a direct substitute. Both parts share identical electrical specifications (26.1 Ohms ±1%, 0.125W), package format (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and regulatory compliance (RoHS3, REACH unaffected). The seated height difference (0.024" vs 0.026") is within acceptable mechanical tolerance for standard PCB designs.

Q: What is the difference between automotive-qualified and non-automotive substitutes?

A: CRCW080526R1FKEA, ERJ-6ENF26R1V, and RMCF0805FT26R1 carry AEC-Q200 automotive qualification, indicating enhanced reliability testing and quality assurance for automotive applications. RC0805FR-0726R1L does not carry this designation. For non-automotive applications, all four substitutes are electrically and mechanically equivalent. For automotive applications, AEC-Q200 qualified parts are recommended.

Q: Are there packaging format differences among the substitute parts?

A: RC2012F26R1CS, RC0805FR-0726R1L, ERJ-6ENF26R1V, and RMCF0805FT26R1 are supplied in Tape & Reel (TR) format. CRCW080526R1FKEA is available in both Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) formats. All parts use identical 0805 (2012 Metric) package format with two terminations, ensuring mechanical compatibility on PCBs designed for the original component.

Q: How do seated height variations affect PCB design?

A: Seated height ranges from 0.020" (0.50mm) for CRCW080526R1FKEA to 0.028" (0.70mm) for ERJ-6ENF26R1V. The original RC2012F26R1CS specifies 0.026" (0.66mm). These variations are within standard PCB design tolerances and do not affect electrical performance. Height differences may impact clearance in applications with tight vertical constraints or specific conformal coating requirements.

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

A: Yes. All substitute parts, including RC2012F26R1CS, maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: What inventory availability should be considered for production planning?

A: RC0805FR-0726R1L (YAGEO) offers the highest inventory availability at 158,058 Pcs. ERJ-6ENF26R1V (Panasonic) provides 79,225 Pcs. CRCW080526R1FKEA (Vishay Dale) has 14,860 Pcs available. RMCF0805FT26R1 (Stackpole) has the lowest availability at 844 Pcs. For high-volume production, YAGEO or Panasonic substitutes are recommended based on supply continuity.
