Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: Select CR0603-FX-1910ELF (Bourns Inc.) or RC0603FR-07191RL (YAGEO) as primary substitutes. Both maintain identical electrical specifications and standard industrial qualification. CR0603-FX-1910ELF is supplied in Tape & Reel format with 19,812 pieces in stock. RC0603FR-07191RL offers the highest inventory availability at 127,114 pieces in stock, providing supply chain flexibility.

For Automotive Applications: Select from AEC-Q200 qualified alternatives: AC0603FR-07191RL (YAGEO), CRCW0603191RFKEA (Vishay Dale), ERJ-3EKF1910V (Panasonic Electronic Components), or RMCF0603FT191R (Stackpole Electronics Inc). All four parts carry automotive-grade certification with identical electrical parameters. RMCF0603FT191R provides the highest inventory level at 81,103 pieces. ERJ-3EKF1910V offers 64,512 pieces in stock.

For Supply Chain Optimization: All substitute parts are Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), eliminating handling restrictions. Selection should prioritize inventory availability and lead time requirements specific to procurement timelines.

Physical Compatibility Note: CRCW0603191RFKEA exhibits minor dimensional variation (0.061" L x 0.033" W, height 0.020" maximum) compared to standard 0603 specifications (0.063" L x 0.031" W, height 0.022" maximum). This variation remains within acceptable PCB footprint tolerances for 0603 package format but should be verified against specific PCB design constraints if tight spacing is present.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07191RL (YAGEO) be used as a direct replacement for RC1608F1910CS (Samsung)?

A: Yes. RC0603FR-07191RL meets all mandatory electrical and mechanical parameters: 191 Ohms ±1%, 0.1W power rating, 0603 (1608 Metric) package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, ROHS3 compliance, and MSL 1 rating. Both are standard industrial-grade components with Active product status.

Q: What is the difference between standard and AEC-Q200 qualified substitutes?

A: AEC-Q200 qualification indicates automotive-grade reliability testing and qualification per Automotive Electronics Council standards. AC0603FR-07191RL, CRCW0603191RFKEA, ERJ-3EKF1910V, and RMCF0603FT191R carry AEC-Q200 designation. The RC1608F1910CS, CR0603-FX-1910ELF, and RC0603FR-07191RL are standard industrial-grade without automotive qualification. Selection depends on application requirements; automotive applications require AEC-Q200 parts.

Q: Are there packaging format differences between substitutes?

A: The RC1608F1910CS is supplied in Cut Tape (CT) format. All substitute parts are supplied in Tape & Reel (TR) format. Both packaging formats are compatible with standard pick-and-place assembly equipment. Cut Tape format is typically used for lower-volume manual assembly or kit applications, while Tape & Reel is standard for high-volume automated production.

Q: Does CRCW0603191RFKEA have different physical dimensions?

A: CRCW0603191RFKEA dimensions are 0.061" L x 0.033" W with 0.020" maximum height, compared to standard 0603 dimensions of 0.063" L x 0.031" W with 0.022" maximum height. This represents minor variation within 0603 package tolerance range. Verify PCB footprint design if component placement involves tight spacing or high-density layouts.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07191RL (YAGEO) provides the highest inventory at 127,114 pieces in stock. RMCF0603FT191R (Stackpole) offers 81,103 pieces, and ERJ-3EKF1910V (Panasonic) provides 64,512 pieces. Inventory levels support rapid procurement for both standard and high-volume production requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification identical to the RC1608F1910CS. All parts are also REACH unaffected, meeting current environmental and regulatory requirements for industrial and consumer electronics applications.

Q: Can substitutes be intermixed in the same production run?

A: Yes. All substitute parts maintain identical electrical specifications (191 Ohms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C), identical package format (0603 / 1608 Metric), and identical compliance certifications (ROHS3, MSL 1). Intermixing is electrically and mechanically compatible. However, verify that design documentation and bill of materials reflect the specific part number used for traceability and future service requirements.
