Substitute Part Grouping Explanation

Substitute parts for the RC5025F19R6CS are qualified based on the following substitution criteria:

Mandatory Matching Parameters:

• Resistance value: 19.6 Ohms (exact)
• Tolerance: ±1% (exact)
• Package / Case: 2010 (5025 Metric) (exact)
• Composition: Thick Film (exact)
• Temperature Coefficient: ±100ppm/°C (exact)
• Operating Temperature Range: -55°C ~ 155°C (exact or exceeding)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) or equivalent

Allowable Variations:

• Power Rating: Substitutes with equal or higher power ratings (0.667W or greater) are acceptable, as increased power dissipation capability does not compromise circuit function
• Packaging Format: Tape & Reel (TR) is compatible with bulk or alternative packaging for the same component footprint
• Manufacturer: Different manufacturers acceptable provided all electrical and mechanical specifications align
• Product Status: Active or Not For New Designs both qualify as functional substitutes; product status reflects design lifecycle only

Identified Substitute Parts:

1. CRCW201019R6FKEF (Vishay Dale) – 0.75W, 3/4W, Automotive AEC-Q200
2. ERJ-12SF19R6U (Panasonic Electronic Components) – 0.75W, 3/4W, Automotive AEC-Q200, Not For New Designs

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RC5025F19R6CS): The Samsung Electro-Mechanics RC5025F19R6CS is the specified component with Active product status, indicating ongoing manufacturer support and availability. Selection of this part is appropriate for new designs and applications requiring standard industrial-grade thick film resistor performance with moisture-resistant construction.

First Alternative (CRCW201019R6FKEF): The Vishay Dale CRCW201019R6FKEF is a direct functional equivalent with Active product status. This substitute provides identical electrical specifications with increased power rating (0.75W versus 0.667W), offering enhanced thermal margin. The component includes AEC-Q200 automotive qualification, which provides additional reliability assurance through automotive-grade testing and qualification standards. This part is suitable for applications requiring automotive-grade components or where higher power dissipation margin is beneficial.

Secondary Alternative (ERJ-12SF19R6U): The Panasonic Electronic Components ERJ-12SF19R6U meets all electrical and mechanical substitution criteria with identical specifications to the Vishay Dale alternative. However, this component carries "Not For New Designs" product status, indicating the manufacturer has discontinued active development and support. This part is suitable only for legacy system maintenance, repair, or replacement applications where existing inventory or established supply chains are in place. New design implementations should not select this component.

Compliance and Certification: All three parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory conformance and simplified handling requirements. The substitute parts' AEC-Q200 automotive qualification does not restrict use in non-automotive applications and represents an additional quality assurance layer.

Frequently Asked Questions (FAQ)

Q: Can CRCW201019R6FKEF replace RC5025F19R6CS in existing designs?

A: Yes. The CRCW201019R6FKEF is a direct functional substitute with matching resistance (19.6 Ohms), tolerance (±1%), package (2010), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W versus 0.667W) does not create incompatibility; it provides additional thermal capacity. Physical dimensions are identical within tolerance (height difference: 0.028" versus 0.026" maximum seated height). Both parts are RoHS3 compliant with MSL 1 rating.

Q: What is the difference between the Samsung and Vishay parts?

A: The primary differences are manufacturer identity and power rating. The Vishay CRCW201019R6FKEF provides 0.75W (3/4W) power rating compared to the Samsung RC5025F19R6CS at 0.667W (2/3W). The Vishay part includes AEC-Q200 automotive qualification. All electrical specifications (resistance, tolerance, temperature coefficient, operating range) are identical. Both are Active status products with equivalent availability and support.

Q: Why is ERJ-12SF19R6U marked "Not For New Designs"?

A: "Not For New Designs" is a product lifecycle designation indicating the manufacturer (Panasonic) has transitioned this component to end-of-life status and is not actively developing or promoting it for new applications. This status reflects manufacturer business decisions, not component performance or quality. The part remains functionally equivalent and suitable for legacy system support or replacement applications where existing supply exists.

Q: Are there height differences that affect PCB layout?

A: Seated height differences exist: RC5025F19R6CS maximum 0.026" (0.66mm), while CRCW201019R6FKEF and ERJ-12SF19R6U maximum 0.028" (0.70mm). This 0.002" (0.04mm) difference is within typical PCB assembly tolerances and does not create functional incompatibility. Verify clearance in applications with height-constrained layouts (such as low-profile assemblies or components with minimal vertical spacing).

Q: Can these parts be used interchangeably in automotive applications?

A: The Vishay CRCW201019R6FKEF and Panasonic ERJ-12SF19R6U both carry AEC-Q200 automotive qualification, making them suitable for automotive-grade applications. The Samsung RC5025F19R6CS does not specify automotive qualification but meets all electrical and environmental specifications required for automotive use. Automotive application requirements should be verified against specific design standards and qualification documentation.

Q: What packaging formats are available for these parts?

A: The RC5025F19R6CS is available in standard packaging (format not specified in provided data). The CRCW201019R6FKEF and ERJ-12SF19R6U are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated PCB assembly and is compatible with standard pick-and-place equipment. Confirm packaging requirements with procurement specifications before ordering.

Q: Are all three parts RoHS3 compliant?

A: Yes. All three parts—RC5025F19R6CS, CRCW201019R6FKEF, and ERJ-12SF19R6U—are RoHS3 compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture control requirements during storage or handling.
