Parameter Comparison

Engineering Selection Recommendations

The ERJ-XGNF2401Y (Panasonic Electronic Components) is a direct functional and mechanical equivalent to the RC0402F242CS (Samsung Electro-Mechanics). Both components satisfy identical electrical specifications, package requirements, and regulatory compliance standards.

Selection Basis:

Both parts maintain Active product status and carry full RoHS3 compliance certification with REACH Unaffected designation, confirming suitability for regulated markets and applications requiring environmental compliance documentation.

The Panasonic ERJ-XGNF2401Y demonstrates a superior temperature coefficient specification (±200ppm/°C versus ±250ppm/°C), indicating enhanced thermal stability across the full operating range of -55°C to 125°C. This characteristic provides additional margin for precision applications, though both values remain within acceptable tolerances for standard circuit design.

Both components feature MSL 1 (Unlimited) moisture sensitivity classification, eliminating moisture-related handling restrictions and enabling extended shelf life without specialized storage requirements.

Component selection between these two parts should be based on supply availability, procurement lead times, cost considerations, and existing supplier relationships, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-XGNF2401Y be used as a direct replacement for the RC0402F242CS in existing designs?

A: Yes. The ERJ-XGNF2401Y is a direct substitute. Both components share identical resistance value (2.4 kOhms), tolerance (±1%), power rating (0.03W), package format (01005/0402 Metric), operating temperature range (-55°C to 125°C), and regulatory compliance status. No circuit redesign or PCB layout modification is required.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the RC0402F242CS and ERJ-XGNF2401Y are manufactured to identical 01005 (0402 Metric) specifications with dimensions of 0.016" L x 0.008" W (0.40mm x 0.20mm) and maximum seated height of 0.006" (0.15mm). They are mechanically interchangeable on PCB assemblies.

Q: What is the significance of the temperature coefficient difference?

A: The Panasonic ERJ-XGNF2401Y has a temperature coefficient of ±200ppm/°C compared to the Samsung RC0402F242CS at ±250ppm/°C. This means the Panasonic part exhibits slightly less resistance variation across temperature extremes. For most applications, both values are acceptable. In precision analog circuits or temperature-sensitive measurement applications, the lower coefficient of the Panasonic part may provide marginal performance advantage.

Q: Are both parts suitable for moisture-sensitive environments?

A: Yes. Both components carry MSL 1 (Unlimited) moisture sensitivity level classification, indicating they do not require special moisture-controlled storage or handling procedures. They can be stored and handled under standard industrial conditions without desiccant packaging or humidity controls.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the RC0402F242CS and ERJ-XGNF2401Y are RoHS3 compliant and REACH Unaffected, confirming compliance with current environmental and hazardous substance regulations applicable to electronic components in regulated markets.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Since both components are electrically and mechanically equivalent with identical package specifications, they can be used interchangeably within the same assembly or production run. However, standard component traceability and documentation practices should be maintained to record which manufacturer's part was used in specific units.

Q: What packaging format is used for both parts?

A: Both the RC0402F242CS and ERJ-XGNF2401Y are supplied in Tape & Reel (TR) format, the standard packaging for automated PCB assembly processes. This format ensures compatibility with standard pick-and-place equipment and reflow soldering processes.
