Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1180CS is determined by strict equivalence across the following critical parameters: resistance value (118 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, MSL 1). All identified substitute parts maintain these core specifications. Substitute parts are categorized as follows:

Direct Equivalent: RC0402FR-07118RL (YAGEO) matches all electrical and mechanical specifications with identical power rating (0.063W).

Upgrade Category: ERJ-2RKF1180X (Panasonic) provides higher power rating (0.1W vs. 0.063W) with automotive AEC-Q200 qualification, suitable for applications requiring enhanced thermal performance.

Similar Category: CRCW0402118RFKED (Vishay Dale) and RMCF0402FT118R (Stackpole Electronics) maintain identical specifications to the main part while offering automotive AEC-Q200 certification for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RC0402FR-07118RL (YAGEO) is the direct equivalent substitute, maintaining identical electrical specifications and power rating. Selection is appropriate for applications where the original Samsung part is unavailable and non-automotive applications are specified.

ERJ-2RKF1180X (Panasonic) is suitable for applications requiring higher power dissipation capability (0.1W vs. 0.063W) combined with automotive AEC-Q200 qualification. This upgrade path is applicable when thermal margin enhancement is required without changing circuit topology.

CRCW0402118RFKED (Vishay Dale) and RMCF0402FT118R (Stackpole Electronics) are applicable for automotive and industrial applications requiring AEC-Q200 certification while maintaining identical power rating and electrical specifications to the original part. Both parts support direct substitution in designs where automotive-grade reliability is mandated.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package dimensions, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07118RL (YAGEO) be used as a direct replacement for RC1005F1180CS (Samsung)?

A: Yes. RC0402FR-07118RL matches all critical electrical and mechanical parameters: 118 Ohms ±1%, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. No circuit modifications are required.

Q: What is the difference between the main part and ERJ-2RKF1180X (Panasonic)?

A: ERJ-2RKF1180X provides higher power rating (0.1W vs. 0.063W) and includes automotive AEC-Q200 certification. All other electrical specifications remain identical. This part is suitable for applications requiring enhanced thermal performance or automotive qualification.

Q: Are CRCW0402118RFKED and RMCF0402FT118R interchangeable with RC1005F1180CS?

A: Yes. Both parts maintain identical specifications to the main part (118 Ohms ±1%, 0.063W, 0402 package, ±100ppm/°C, -55°C to 155°C) and add automotive AEC-Q200 certification. They are suitable for direct substitution in both commercial and automotive applications.

Q: Does package format differ among these substitute parts?

A: No. All parts use the 0402 (1005 Metric) package format with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.016" / 0.40mm). PCB footprints and assembly processes remain unchanged.

Q: What is the significance of MSL 1 rating for all these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life under standard storage conditions (23°C ±2°C, 45% to 75% relative humidity). No special moisture control or baking procedures are required prior to assembly for any of these parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC0402FR-07118RL, ERJ-2RKF1180X, CRCW0402118RFKED, and RMCF0402FT118R all maintain ROHS3 compliance, matching the regulatory status of the original RC1005F1180CS part.
