Key Parameters

Substitute Part Grouping Explanation

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

Electrical Specifications: Resistance value (19.1 Ohms), tolerance (±1%), and power rating (0.1W) must be identical.

Package Compatibility: All substitute parts must use 0603 (1608 Metric) package format to ensure PCB footprint compatibility and assembly process alignment.

Environmental Performance: Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) must match or exceed the main part specifications.

Compliance Requirements: RoHS3 compliance and MSL 1 rating are mandatory for all substitutes.

Composition: Thick film construction is required for thermal and electrical performance consistency.

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification are noted as enhancements but do not disqualify parts from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are functionally equivalent to the RC1608F19R1CS based on electrical and mechanical parameter alignment. Selection among these alternatives should be based on the following criteria:

Direct Equivalent: RC0603FR-0719R1L (YAGEO) provides direct substitution with identical moisture-resistant thick film construction and matching physical dimensions (0.063" L x 0.031" W, 0.022" height maximum).

Automotive-Grade Options: CRCW060319R1FKEA (Vishay Dale), ERJ-3EKF19R1V (Panasonic), and RMCF0603FT19R1 (Stackpole) incorporate Automotive AEC-Q200 certification. These parts are suitable for applications requiring automotive-grade reliability and are interchangeable with the main part in non-automotive applications.

Inventory Availability: YAGEO RC0603FR-0719R1L offers highest inventory (8,684 pcs), followed by Panasonic ERJ-3EKF19R1V (49,877 pcs). Vishay Dale CRCW060319R1FKEA provides 25,936 pcs. Stackpole RMCF0603FT19R1 has limited availability (1,112 pcs).

Compliance Status: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility across all options.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0719R1L replace RC1608F19R1CS directly on the PCB?

A: Yes. Both parts share identical 0603 (1608 Metric) package dimensions, footprint, and electrical specifications. No PCB layout modifications are required.

Q: What is the difference between the moisture-resistant Samsung part and the automotive-grade substitutes?

A: The Samsung RC1608F19R1CS is specified as moisture-resistant thick film. The Vishay Dale CRCW060319R1FKEA, Panasonic ERJ-3EKF19R1V, and Stackpole RMCF0603FT19R1 incorporate Automotive AEC-Q200 certification, indicating enhanced reliability testing and qualification for automotive applications. Both feature sets are compatible for general industrial and consumer applications.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist. Samsung and YAGEO parts measure 0.063" L x 0.031" W with 0.022" maximum height. Vishay Dale measures 0.061" L x 0.033" W with 0.020" maximum height. Stackpole measures 0.061" L x 0.031" W with 0.022" maximum height. These variations remain within standard 0603 package tolerances and do not affect PCB compatibility.

Q: Do all substitute parts have the same temperature coefficient?

A: Yes. All parts, including the main part RC1608F19R1CS, specify ±100ppm/°C temperature coefficient and operate across the identical -55°C ~ 155°C temperature range.

Q: Which substitute part offers the best supply availability?

A: Panasonic ERJ-3EKF19R1V provides the highest inventory at 49,877 pcs, followed by Vishay Dale CRCW060319R1FKEA at 25,936 pcs. YAGEO RC0603FR-0719R1L offers 8,684 pcs. Stackpole RMCF0603FT19R1 has the lowest availability at 1,112 pcs.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the main part.
