Panasonic ERJ-S08F1181V 1.18kΩ 1% 1/4W 1206 Chip Resistor Equivalent & Substitute Parts
Part Overview
The Panasonic ERJ-S08F1181V is a 1.18 kOhms ±1% thick film chip resistor in 1206 (3216 Metric) package rated for 0.25W power dissipation. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for automotive and industrial applications requiring high reliability in harsh environments. The part is currently in active production status with 807 units in stock.
Substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design flexibility permits equivalent alternatives from qualified manufacturers. All substitute parts listed maintain identical electrical specifications and package dimensions, ensuring direct functional replacement.

Substitute Part Grouping Explanation
Substitution eligibility for the ERJ-S08F1181V is determined by strict equivalence across the following parameters:
- Resistance value: 1.18 kOhms
- Tolerance: ±1%
- Power rating: 0.25W
- Package: 1206 (3216 Metric)
- Composition: Thick Film
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C to 155°C
- RoHS3 compliance
- MSL rating: 1 (Unlimited)
All listed substitute parts meet these criteria. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (anti-sulfur coating, moisture resistance), and product lifecycle status do not affect electrical or mechanical interchangeability.
Parameter Comparison
| Manufacturer Part Number | Manufacturer | Resistance | Tolerance | Power (W) | Package | Temp Coeff (ppm/°C) | Op. Temp Range (°C) | Product Status | Packaging Format |
|---|---|---|---|---|---|---|---|---|---|
| ERJ-S08F1181V | Panasonic Electronic Components | 1.18 kΩ | ±1% | 0.25 | 1206 | ±100 | -55 to 155 | Active | Tape & Reel |
| ERJ-8ENF1181V | Panasonic Electronic Components | 1.18 kΩ | ±1% | 0.25 | 1206 | ±100 | -55 to 155 | Not For New Designs | Cut Tape & Digi-Reel |
| CRCW12061K18FKEA | Vishay Dale | 1.18 kΩ | ±1% | 0.25 | 1206 | ±100 | -55 to 155 | Active | Tape & Reel |
| RC1206FR-071K18L | YAGEO | 1.18 kΩ | ±1% | 0.25 | 1206 | ±100 | -55 to 155 | Active | Tape & Reel |

Engineering Selection Recommendations
For new designs, select from parts with Active product status: CRCW12061K18FKEA (Vishay Dale), RC1206FR-071K18L (YAGEO), or RMCF1206FT1K18 (Stackpole Electronics Inc). All three maintain full RoHS3 compliance and MSL 1 rating.
The primary part ERJ-S08F1181V remains the preferred choice for automotive applications requiring AEC-Q200 qualification with anti-sulfur coating. RMCF1206FT1K18 and CRCW12061K18FKEA also carry AEC-Q200 ratings and are suitable for automotive environments.
ERJ-8ENF1181V, while electrically equivalent, carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where supply of active alternatives is unavailable.
Frequently Asked Questions (FAQ)
Q: Can CRCW12061K18FKEA replace ERJ-S08F1181V in automotive applications?
A: Yes. CRCW12061K18FKEA meets all electrical and mechanical specifications and carries AEC-Q200 automotive qualification. Both parts are in active production with identical resistance, tolerance, power rating, and operating temperature range.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly. Cut Tape & Digi-Reel is pre-cut into smaller quantities. Both formats contain identical components; packaging format selection depends on assembly equipment and order quantity requirements.
Q: Is ERJ-8ENF1181V suitable for new product designs?
A: No. ERJ-8ENF1181V carries "Not For New Designs" status. Use active alternatives such as CRCW12061K18FKEA, RC1206FR-071K18L, or RMCF1206FT1K18 for new designs.
Q: Do all substitute parts meet RoHS3 compliance?
A: Yes. All listed parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.
Q: What distinguishes anti-sulfur coating from moisture-resistant coating?
A: Anti-sulfur coating protects against hydrogen sulfide exposure in harsh industrial environments. Moisture-resistant coating provides protection against humidity and condensation. Both are protective features; selection depends on specific environmental exposure conditions.
