Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1910CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 191 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance
• Number of Terminations: 2

Allowable Variation:

• Power rating may be equal or higher (0.063W minimum)
• Composition must remain thick film
• Packaging format (Tape & Reel or Cut Tape) does not affect electrical equivalence

Substitute parts are grouped into two categories based on power rating alignment:

Direct Equivalents (1/16W, 0.063W): Parts with identical power rating to the main part.

Upgrade Equivalents (1/10W, 0.1W or higher): Parts with higher power dissipation capability, suitable for applications requiring enhanced thermal performance while maintaining all other electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

RC0402FR-07191RL (YAGEO): Direct electrical and mechanical equivalent with identical power rating. Suitable for direct replacement in non-automotive applications. Maintains all compliance certifications and operating specifications of the main part.

ERJ-2RKF1910X (Panasonic Electronic Components): Upgrade substitute with enhanced power rating (0.1W vs. 0.063W). Includes AEC-Q200 automotive qualification. Recommended for applications requiring automotive-grade reliability or thermal margin enhancement while maintaining identical resistance, tolerance, and temperature characteristics.

CRCW0402191RFKED (Vishay Dale): Direct equivalent with AEC-Q200 automotive qualification. Identical power rating and electrical specifications. Suitable for applications requiring automotive-grade components without power rating upgrade.

RMCF0402FT191R (Stackpole Electronics Inc): Direct equivalent with AEC-Q200 automotive qualification. Identical power rating and electrical specifications. Suitable for applications requiring automotive-grade components without power rating upgrade.

All substitute parts maintain RoHS3 compliance, MSL Level 1 rating, and identical operating temperature range. Selection between direct equivalents and upgrade equivalents depends on application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07191RL replace RC1005F1910CS in any application?

A: Yes. RC0402FR-07191RL is a direct electrical and mechanical equivalent with identical resistance (191 Ohms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No design modifications are required.

Q: What is the difference between the main part and the Panasonic ERJ-2RKF1910X?

A: The primary difference is power rating: ERJ-2RKF1910X is rated at 0.1W (1/10W) compared to 0.063W (1/16W) for RC1005F1910CS. All other electrical parameters are identical. ERJ-2RKF1910X includes AEC-Q200 automotive qualification. The higher power rating provides thermal margin for demanding applications.

Q: Are the Vishay Dale CRCW0402191RFKED and Stackpole RMCF0402FT191R interchangeable with the main part?

A: Yes. Both parts are direct equivalents with identical resistance, tolerance, power rating, package, and temperature specifications. Both include AEC-Q200 automotive qualification. They differ only in manufacturer and series designation.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Can I use ERJ-2RKF1910X in place of RC1005F1910CS if the application only requires 1/16W power dissipation?

A: Yes. A higher power-rated component (0.1W) operates safely in applications requiring lower power dissipation (0.063W). The component will not be stressed and will operate within its thermal limits.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies that the component meets automotive reliability, temperature cycling, and performance requirements. Components with AEC-Q200 qualification are suitable for automotive and high-reliability applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, matching the compliance status of the main part RC1005F1910CS.

Q: What is MSL Level 1 rating?

A: MSL (Moisture Sensitivity Level) Level 1 indicates unlimited shelf life without moisture baking requirements. The component can be stored and handled without special moisture control procedures.
