Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F26R7CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 26.7 Ohms
• 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
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

All identified substitute parts meet these mandatory parameters without exception. Substitutes may differ in specific features (such as automotive qualification or anti-sulfur properties) and physical dimensions (height seated maximum), provided these differences do not impact functional performance in the target application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F26R7CS, ERJ-6ENF26R7V, and RC0805FR-0726R7L—are functionally equivalent for applications requiring a 26.7 Ohm ±1% 0.125W thick film resistor in 0805 package format. Selection among these parts should be based on the following criteria:

RCS2012F26R7CS (Samsung Electro-Mechanics): Primary choice when anti-sulfur and moisture-resistant properties are specified. Maintains Active product status with established inventory availability.

ERJ-6ENF26R7V (Panasonic Electronic Components): Suitable for automotive and mission-critical applications requiring AEC-Q200 qualification. Highest inventory availability (42,625 units) supports high-volume production requirements. Acceptable height variation (0.028" maximum) for standard PCB assembly processes.

RC0805FR-0726R7L (YAGEO): Appropriate for cost-sensitive applications where moisture resistance is required. Lowest seated height (0.024" maximum) accommodates space-constrained designs. Adequate inventory (5,365 units) for standard production volumes.

All parts comply with ROHS3 and maintain MSL 1 (Unlimited) ratings, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF26R7V replace RCS2012F26R7CS in a non-automotive application?

A: Yes. The ERJ-6ENF26R7V meets all mandatory electrical and mechanical parameters required for substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in general-purpose applications.

Q: What is the significance of the height difference between substitute parts?

A: Height variations (0.024" to 0.028" maximum seated height) fall within standard PCB assembly tolerances and do not affect electrical performance. Verify clearance requirements for your specific PCB layout and component placement constraints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS2012F26R7CS, ERJ-6ENF26R7V, and RC0805FR-0726R7L are all ROHS3 Compliant, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Do substitute parts maintain the same temperature coefficient?

A: Yes. All three parts specify ±100ppm/°C temperature coefficient and operate across the identical -55°C ~ 155°C temperature range, ensuring consistent performance across thermal cycling and environmental conditions.

Q: Which substitute part offers the best inventory availability?

A: ERJ-6ENF26R7V (Panasonic) provides the highest inventory level at 42,625 units, followed by RC0805FR-0726R7L (YAGEO) at 5,365 units. RCS2012F26R7CS (Samsung) maintains 969 units in stock.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All parts are mechanically and electrically equivalent in 0805 (2012 Metric) package format with identical electrical specifications. Standard pick-and-place equipment and reflow processes accommodate all three parts without modification.
