Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F1180CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 118 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

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

Environmental & Compliance Parameters:

• Composition: Thick Film
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts listed maintain identical electrical specifications and package dimensions. Variations in seated height and additional certifications (such as AEC-Q200 automotive qualification) do not affect substitution eligibility for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RC2012F1180CS, RC0805FR-07118RL, CRCW0805118RFKEA, and ERJ-6ENF1180V—are functionally equivalent for direct substitution in circuits requiring a 118 Ohms ±1% 0.125W 0805 chip resistor.

Direct Equivalent (Preferred for Drop-In Replacement): RC0805FR-07118RL (YAGEO) is the closest direct equivalent, matching all electrical and mechanical specifications with identical moisture resistance features and Active product status.

Alternative Selections with Enhanced Ratings: CRCW0805118RFKEA (Vishay Dale) and ERJ-6ENF1180V (Panasonic) both include Automotive AEC-Q200 certification. These parts are suitable for general-purpose applications and provide additional qualification for automotive environments. The seated height variations (0.020" and 0.028" respectively) remain within acceptable PCB assembly tolerances for 0805 packages.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07118RL replace RC2012F1180CS directly on the PCB? A: Yes. Both parts share identical electrical specifications (118 Ohms ±1%, 0.125W), package dimensions (0805/2012 Metric), and environmental ratings. The 0.002" difference in seated height (0.024" vs 0.026") is within standard PCB assembly tolerances.

Q: What is the difference between the Samsung and YAGEO versions? A: The RC2012F1180CS (Samsung) and RC0805FR-07118RL (YAGEO) are functionally identical. Both are moisture-resistant thick film resistors with matching electrical and mechanical specifications. Selection between them depends on supplier availability and inventory levels.

Q: Why do CRCW0805118RFKEA and ERJ-6ENF1180V include AEC-Q200 certification? A: AEC-Q200 is an automotive qualification standard. These parts meet additional reliability and testing requirements for automotive applications. For general-purpose circuits, this certification does not affect substitution eligibility but provides enhanced qualification documentation.

Q: Are there any height restrictions when substituting these parts? A: The seated height variations range from 0.020" to 0.028" across all four parts. Standard 0805 PCB designs accommodate this range. Verify clearance in applications with height-constrained layouts, such as those with low-profile components or shielding.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All four parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used interchangeably in high-temperature applications? A: Yes. All parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient, meeting identical thermal performance requirements.

Q: What is the inventory status for each part? A: RC2012F1180CS: 802 Pcs; RC0805FR-07118RL: 7,663 Pcs; CRCW0805118RFKEA: 29,712 Pcs; ERJ-6ENF1180V: 78,962 Pcs. Availability may vary by supplier and time of order.
