RC0402F2492CS Equivalent & Substitute Parts

Part Overview

The RC0402F2492CS is a 24.9 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 01005 (0402 Metric) package format. This component is rated for 0.03W (1/32W) power dissipation and is designed for moisture-resistant applications across industrial and commercial temperature ranges. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when components share identical electrical specifications, mechanical dimensions, and environmental compliance ratings. This ensures direct interchangeability in circuit designs without performance degradation or reliability concerns.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0402F2492CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 24.9 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.03W / 1/32W (exact match)
• Temperature coefficient: ±250ppm/°C (exact match)
• Operating temperature range: -55°C to 125°C (exact match)

Mechanical Equivalence Requirements:

• Package format: 01005 (0402 Metric) (exact match)
• Physical dimensions: 0.016" L x 0.008" W / 0.40mm x 0.20mm (exact match)
• Height - Seated (Max): 0.006" (0.15mm) (exact match)
• Number of terminations: 2 (exact match)

Compliance Equivalence Requirements:

• RoHS3 compliance (required)
• Moisture Sensitivity Level: MSL 1 (required)
• REACH status: REACH Unaffected (required)

Substitute parts must satisfy all three equivalence categories to ensure direct interchangeability without circuit redesign, PCB layout modification, or performance verification testing.

Parameter Comparison

Engineering Selection Recommendations

The CRCW010024K9FREL manufactured by Vishay Dale is a direct equivalent substitute for the RC0402F2492CS. Both components are Active products with identical electrical specifications, mechanical dimensions, and environmental compliance certifications.

Selection Basis:

All critical parameters align across electrical performance, physical form factor, and regulatory compliance. Both parts are RoHS3 compliant, REACH unaffected, and rated for MSL 1 (unlimited moisture sensitivity). The 01005 (0402 Metric) package format ensures PCB footprint compatibility without layout modification.

The substitute part maintains the same temperature coefficient (±250ppm/°C), operating temperature range (-55°C to 125°C), and power dissipation rating (0.03W / 1/32W). Tolerance specification (±1%) is identical, ensuring equivalent circuit performance in applications requiring precision resistor networks.

Component selection between the RC0402F2492CS and CRCW010024K9FREL may be based on inventory availability, lead time, supplier preference, or cost considerations. Both parts are suitable for direct substitution in active production designs.

Frequently Asked Questions (FAQ)

Q: Can the CRCW010024K9FREL replace the RC0402F2492CS in existing circuit designs?

A: Yes. The CRCW010024K9FREL is a direct equivalent substitute. All electrical parameters (resistance, tolerance, power rating, temperature coefficient), mechanical dimensions (01005 package, 0.40mm x 0.20mm), and compliance certifications (RoHS3, MSL 1) are identical. No circuit redesign or PCB layout modification is required.

Q: Are there any differences in moisture sensitivity or environmental performance?

A: No. Both the RC0402F2492CS and CRCW010024K9FREL are rated MSL 1 (unlimited moisture sensitivity level) and are REACH unaffected. Operating temperature ranges are identical (-55°C to 125°C). Environmental performance characteristics are equivalent.

Q: What determines if a resistor can substitute for the RC0402F2492CS?

A: Substitution requires exact equivalence across three categories: (1) Electrical specifications—resistance value (24.9 kOhms), tolerance (±1%), power rating (0.03W), and temperature coefficient (±250ppm/°C); (2) Mechanical specifications—01005 package format and physical dimensions (0.40mm x 0.20mm); (3) Compliance certifications—RoHS3 compliance and MSL 1 rating. All three categories must match exactly.

Q: Can resistors with different tolerance values substitute for the RC0402F2492CS?

A: No. The RC0402F2492CS specifies ±1% tolerance. Substitutes must maintain identical tolerance. Resistors with ±5% or other tolerance values are not equivalent and may cause circuit performance degradation in precision applications.

Q: Is the 01005 package format critical for substitution?

A: Yes. The 01005 (0402 Metric) package format is a mechanical requirement for PCB footprint compatibility. Substitutes must use the identical package format. Different package sizes (0603, 0805, etc.) require PCB redesign and are not direct substitutes.

Q: What is the significance of the ±250ppm/°C temperature coefficient?

A: The temperature coefficient specifies resistance value drift across the operating temperature range (-55°C to 125°C). Substitutes must maintain identical temperature coefficient to ensure equivalent circuit stability and performance across temperature extremes. Different temperature coefficients indicate different thermal behavior and are not equivalent.

Q: Are there any packaging or supply chain differences between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging format. The RC0402F2492CS has 665 pieces in stock inventory, while the CRCW010024K9FREL has 20,360 pieces available. Packaging format is identical; inventory levels may influence supplier selection and lead time considerations.
