RC1005F2801CS Equivalent & Substitute Parts

Part Overview

The RC1005F2801CS is a 2.8 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated at 0.063W (1/16W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and supply chain continuity for applications requiring this specific resistance value and electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2801CS is determined by strict equivalence across the following critical parameters: resistance value (2.8 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99).

The identified substitute parts are grouped into three categories based on substitution relationship:

Direct Equivalents maintain identical electrical specifications and packaging, differing only in manufacturer and packaging format (Cut Tape vs. Tape & Reel).

Upgrade Substitute provides enhanced power rating (0.1W vs. 0.063W) with automotive AEC-Q200 qualification, suitable for applications requiring higher thermal margin or automotive-grade reliability.

Similar Substitutes maintain all core electrical parameters with automotive AEC-Q200 certification, offering enhanced reliability for demanding applications while preserving the original 0.063W power rating.

All substitute parts share identical mechanical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm), height (0.016" / 0.40mm maximum seated), and regulatory certifications with the main part.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory alignment with the original RC1005F2801CS specification.

CR0402-FX-2801GLF (Bourns Inc.) and RC0402FR-072K8L (YAGEO) are direct electrical equivalents with identical power rating (0.063W) and all core parameters. Selection between these and the main part depends on packaging format requirements (Tape & Reel vs. Cut Tape) and inventory availability.

ERJ-2RKF2801X (Panasonic Electronic Components) provides an upgrade path with enhanced power rating (0.1W vs. 0.063W) and automotive AEC-Q200 qualification. This part is suitable for applications requiring higher thermal margin or automotive-grade reliability assurance.

CRCW04022K80FKED (Vishay Dale) and RMCF0402FT2K80 (Stackpole Electronics Inc) maintain the original 0.063W power rating while adding automotive AEC-Q200 certification. These parts support applications requiring automotive-grade component qualification without power rating modification.

All substitute parts share identical mechanical dimensions, temperature coefficient, operating temperature range, and MSL rating with the main part, ensuring direct PCB compatibility and thermal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2801GLF replace RC1005F2801CS in production?

A: Yes. CR0402-FX-2801GLF is a direct electrical equivalent with identical resistance (2.8 kOhms), tolerance (±1%), power rating (0.063W), package (0402), and temperature specifications. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and manufacturer. Mechanical compatibility is confirmed.

Q: What is the difference between the main part and ERJ-2RKF2801X?

A: ERJ-2RKF2801X provides a higher power rating (0.1W vs. 0.063W) and includes automotive AEC-Q200 qualification. All other electrical parameters remain identical. This upgrade is suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

Q: Are CRCW04022K80FKED and RMCF0402FT2K80 suitable for automotive applications?

A: Yes. Both parts carry automotive AEC-Q200 certification while maintaining the original 0.063W power rating and all core electrical specifications. They are suitable for automotive-grade applications requiring this resistance value.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (Unlimited), identical to the RC1005F2801CS. No additional moisture handling precautions are required during substitution.

Q: Can I use RC0402FR-072K8L as a direct replacement in high-volume production?

A: Yes. RC0402FR-072K8L is a direct electrical equivalent with identical specifications. It is available in both Cut Tape and Digi-Reel® packaging formats, supporting both manual and automated assembly processes. Inventory availability (120,287 pcs) supports high-volume requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the main part.
