Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F11R3CS are qualified based on strict equivalence of the following parameters:

• Electrical Specifications: Resistance value (11.3 Ohms), tolerance (±1%), and power rating (0.125W / 1/8W) must be identical
• Package Dimensions: 0805 (2012 Metric) form factor with compatible physical dimensions (0.079" L x 0.049" W)
• Thermal Characteristics: Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match
• Compliance & Environmental: RoHS3 compliance, MSL Level 1, and REACH unaffected status required
• Composition: Thick film construction maintained across all substitutes

All identified substitute parts meet these criteria and are classified as Active products with current manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

All three components—RCS2012F11R3CS (Samsung Electro-Mechanics), ERJ-6ENF11R3V (Panasonic Electronic Components), and RC0805FR-0711R3L (YAGEO)—are qualified substitutes based on identical electrical and mechanical specifications. Selection between these parts may be determined by:

Compliance Certifications: The ERJ-6ENF11R3V carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability standards. The RCS2012F11R3CS and RC0805FR-0711R3L do not specify AEC-Q200 certification.

Environmental Features: The RCS2012F11R3CS includes anti-sulfur characteristics in addition to moisture resistance. The RC0805FR-0711R3L specifies moisture resistant properties. The ERJ-6ENF11R3V specifies automotive AEC-Q200 qualification.

Physical Height Variation: Seated height ranges from 0.024" (RC0805FR-0711R3L) to 0.028" (ERJ-6ENF11R3V), with RCS2012F11R3CS at 0.026". This variation is within typical PCB assembly tolerances for 0805 packages.

Inventory Availability: Current stock levels are 948 Pcs (Samsung), 50,473 Pcs (Panasonic), and 7,169 Pcs (YAGEO).

All parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF11R3V replace RCS2012F11R3CS in non-automotive applications?

A: Yes. The ERJ-6ENF11R3V meets all electrical and mechanical specifications required for direct substitution. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: All three parts conform to 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W). Seated height variation (0.024" to 0.028") is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit.

Q: Do all substitute parts maintain the same temperature coefficient?

A: Yes. All three parts specify ±100ppm/°C temperature coefficient and operate across the identical temperature range of -55°C ~ 155°C.

Q: What is the significance of MSL Level 1 rating?

A: MSL Level 1 indicates unlimited shelf life without moisture baking requirements, provided components are stored in standard conditions. All three parts carry this rating.

Q: Are there differences in anti-sulfur or moisture resistance between these parts?

A: The RCS2012F11R3CS explicitly includes anti-sulfur and moisture resistant features. The RC0805FR-0711R3L specifies moisture resistant properties. The ERJ-6ENF11R3V specifies automotive AEC-Q200 qualification. All three are suitable for standard industrial environments.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical 0805 package footprints, electrical specifications, and compliance certifications enable direct PCB layout compatibility without design modification.
