Engineering Selection Recommendations

For Standard Applications (Non-Automotive): Direct equivalents CR0402-FX-82R5GLF, RC0402FR-0782R5L, and RMCF0402FT82R5 provide identical electrical and mechanical performance to the RC1005F82R5CS. All three maintain ROHS3 compliance and MSL 1 rating. Selection among these options is based on inventory availability and procurement lead times.

For Automotive Applications: CRCW040282R5FKED and RMCF0402FT82R5 both carry AEC-Q200 automotive qualification while maintaining identical base specifications. These parts are suitable for automotive-grade designs requiring enhanced reliability documentation.

For Enhanced Thermal Performance: ERJ-2RKF82R5X provides upgraded power rating (0.1W vs. 0.063W) with AEC-Q200 qualification. This option is applicable when circuit design margins require higher power dissipation capability within the same package footprint.

Compliance Considerations: CRCW040282R5FKTD exhibits RoHS non-compliance and REACH affected status. This part is restricted to applications where legacy component specifications are mandated or where regulatory exemptions apply. Use of this variant requires explicit design documentation and compliance review.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-82R5GLF directly replace RC1005F82R5CS in existing designs?

A: Yes. CR0402-FX-82R5GLF is a direct equivalent with identical resistance (82.5 Ω), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). Both components are ROHS3 compliant with MSL 1 rating. No circuit redesign is required.

Q: What is the difference between the standard substitute parts and ERJ-2RKF82R5X?

A: ERJ-2RKF82R5X provides a higher power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) baseline. All other electrical parameters remain identical. This upgrade option is applicable when circuit analysis indicates higher power dissipation requirements. The component maintains the same 0402 package footprint and temperature characteristics.

Q: Are all substitute parts suitable for moisture-sensitive applications?

A: All listed substitute parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. RC0402FR-0782R5L and the primary part RC1005F82R5CS explicitly feature moisture-resistant construction. Other substitutes employ standard thick film construction with equivalent moisture performance at MSL 1 level.

Q: Can CRCW040282R5FKTD be used in new designs?

A: CRCW040282R5FKTD is RoHS non-compliant and REACH affected. Use of this part in new designs is restricted to applications where regulatory exemptions are documented or where legacy component specifications are explicitly required. Standard practice restricts this variant to repair and maintenance of existing equipment.

Q: What packaging formats are available for these substitute parts?

A: The primary part RC1005F82R5CS is supplied in Tape & Reel (TR) format. Direct equivalents CR0402-FX-82R5GLF, ERJ-2RKF82R5X, CRCW040282R5FKED, CRCW040282R5FKTD, and RMCF0402FT82R5 are supplied in Tape & Reel (TR) format. RC0402FR-0782R5L is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Do automotive-qualified parts (AEC-Q200) provide performance advantages in non-automotive applications?

A: AEC-Q200 qualification indicates enhanced reliability testing and documentation standards. In non-automotive applications, these parts provide equivalent electrical performance to standard variants. Selection of AEC-Q200 parts is based on design requirements for enhanced traceability and qualification documentation rather than functional performance differences.

Q: What inventory levels are available for each substitute part?

A: Inventory availability is subject to real-time supply chain conditions. RC0402FR-0782R5L (YAGEO) maintains the highest documented inventory at 346,537 pieces. ERJ-2RKF82R5X (Panasonic) has 85,668 pieces available. RMCF0402FT82R5 (Stackpole) has 79,878 pieces. CRCW040282R5FKED (Vishay Dale) has 51,762 pieces. CR0402-FX-82R5GLF (Bourns) has 25,486 pieces. CRCW040282R5FKTD (Vishay Dale) has 10,961 pieces. Procurement decisions should reference current supplier inventory data.
