Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC0603FR-07124RL are qualified based on the following critical parameters:

• Resistance Value: 124 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• RoHS Compliance: RoHS3 Compliant (minimum requirement)
• Moisture Sensitivity: MSL 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria and are manufactured by recognized component suppliers. Substitutes may include additional certifications such as Automotive AEC-Q200 qualification, which represents enhanced reliability screening but does not alter base electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status components with RoHS3 compliance and MSL 1 rating, confirming their suitability for direct replacement of the RC0603FR-07124RL in circuit applications. The primary distinction among substitutes is the presence of Automotive AEC-Q200 certification on AC0603FR-07124RL, CRCW0603124RFKEA, ERJ-3EKF1240V, RMCF0603FG124R, and RMCF0603FT124R. This certification indicates enhanced reliability screening and qualification for automotive-grade applications but does not alter electrical or mechanical compatibility for general-purpose use.

CR0603-FX-1240ELF from Bourns Inc. and the base RC0603FR-07124RL from YAGEO provide equivalent functionality without automotive-specific qualification. Selection between automotive-qualified and non-automotive variants depends on application requirements and supply chain availability. All parts maintain identical resistance, tolerance, power rating, package dimensions, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can AC0603FR-07124RL replace RC0603FR-07124RL directly?

A: Yes. AC0603FR-07124RL is manufactured by YAGEO and matches all critical electrical and mechanical parameters: 124 Ohms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The addition of Automotive AEC-Q200 certification provides enhanced reliability screening but does not affect functional interchangeability.

Q: What is the difference between RMCF0603FG124R and RMCF0603FT124R?

A: Both parts are manufactured by Stackpole Electronics Inc. and share identical electrical specifications: 124 Ohms ±1%, 0.1W, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both carry Automotive AEC-Q200 certification. The difference lies in internal construction or manufacturing process designation (FG vs. FT suffix), but both are functionally equivalent for circuit applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the main part RC0603FR-07124RL, are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, confirming compliance with environmental and hazardous substance restrictions.

Q: Can I use a substitute part with Automotive AEC-Q200 certification in a non-automotive application?

A: Yes. Automotive AEC-Q200 certification represents additional reliability screening and qualification beyond standard requirements. Parts with this certification are fully compatible with non-automotive applications and provide equivalent or enhanced performance characteristics.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to the 0603 (1608 Metric) package standard. Minor dimensional variations exist within tolerance: CRCW0603124RFKEA and RMCF0603FG124R measure 0.061" L x 0.033" W or 0.061" L x 0.031" W respectively, while others measure 0.063" L x 0.031" W. These variations remain within 0603 package specifications and do not affect PCB layout or assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: ERJ-3EKF1240V from Panasonic Electronic Components shows the highest inventory level at 1,282,363 pieces. RMCF0603FT124R from Stackpole Electronics Inc. provides 73,743 pieces, and CRCW0603124RFKEA from Vishay Dale provides 18,845 pieces. Inventory levels are subject to change and should be confirmed with suppliers.
