Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F11R5CS are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Resistance value: 11.5 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2
• Packaging format: Tape & Reel (TR)

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria without exception. Variations in height (seated maximum) and specific feature sets (anti-sulfur, automotive qualification) do not affect functional substitutability within the defined parameter scope.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F11R5CS, ERJ-6ENF11R5V, and RC0805FR-0711R5L—are functionally equivalent for applications requiring 11.5 Ohm ±1% 0.125W 0805 chip resistors. Selection among these parts should be based on:

Procurement Availability: Current inventory levels vary across manufacturers. Samsung Electro-Mechanics RCS2012F11R5CS has 887 units in stock, Panasonic ERJ-6ENF11R5V has 12,003 units, and YAGEO RC0805FR-0711R5L has 6,009 units available.

Application-Specific Requirements: The Panasonic ERJ-6ENF11R5V carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. The Samsung RCS2012F11R5CS includes anti-sulfur properties in addition to moisture resistance. The YAGEO RC0805FR-0711R5L provides moisture-resistant thick film construction.

Compliance Certification: All three parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity level, meeting standard industrial and commercial requirements.

Physical Fit: Height variations (0.026" for Samsung, 0.028" for Panasonic, 0.024" for YAGEO) are within typical PCB assembly tolerances for 0805 packages and do not affect interchangeability in standard applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF11R5V replace RCS2012F11R5CS in any application?

A: Yes. Both parts share identical electrical specifications (11.5 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C), identical package dimensions (0805 / 2012 Metric), and equivalent compliance certifications (ROHS3, MSL 1). The Panasonic part includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the three substitute parts?

A: The three parts are electrically and mechanically identical. Differences exist only in manufacturer-specific features: Samsung RCS2012F11R5CS includes anti-sulfur treatment; Panasonic ERJ-6ENF11R5V carries AEC-Q200 automotive certification; YAGEO RC0805FR-0711R5L is specified as moisture-resistant. Height variations (0.026" to 0.028") are negligible for standard PCB assembly.

Q: Are all three parts suitable for high-reliability applications?

A: All three parts meet ROHS3 compliance and maintain MSL 1 (Unlimited) moisture sensitivity level. Product status is Active for all three manufacturers. Selection for high-reliability applications should consider manufacturer-specific certifications and quality documentation beyond the parameters provided.

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

A: Yes. The 0805 package format, identical electrical specifications, and equivalent physical dimensions ensure direct interchangeability on PCBs designed for RCS2012F11R5CS. No circuit redesign or PCB layout modification is required.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance value change per degree Celsius across the operating range (-55°C ~ 155°C). All three parts share this specification, ensuring consistent thermal performance across applications.

Q: Are there any supply chain advantages to selecting one part over another?

A: Panasonic ERJ-6ENF11R5V currently has the highest inventory (12,003 units), followed by YAGEO RC0805FR-0711R5L (6,009 units) and Samsung RCS2012F11R5CS (887 units). Availability may influence procurement decisions for high-volume production.
