RC1005F2610CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005F2610CS is a 261 Ohms ±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 when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific certification requirements such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2610CS is determined by strict equivalence across the following critical parameters: resistance value (261 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are categorized into three groups:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W) with no functional or performance differences. These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced power rating (0.1W / 1/10W) while maintaining all other electrical parameters. These parts offer improved thermal performance and are backward compatible with applications designed for the original 0.063W rating.

Similar Substitutes match all core electrical and mechanical parameters but include automotive AEC-Q200 certification, adding qualification for automotive applications without altering base performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: CR0402-FX-2610GLF (Bourns Inc.) and RC0402FR-07261RL (YAGEO) provide direct electrical equivalence to RC1005F2610CS. Both maintain identical power rating, tolerance, and temperature specifications. RC0402FR-07261RL includes moisture resistant construction matching the original part. Selection between these options is based on inventory availability and supply chain logistics.

For Automotive Applications: CRCW0402261RFKED (Vishay Dale) and RMCF0402FT261R (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards while maintaining identical electrical specifications and power rating to the original part. These substitutes are appropriate for automotive-grade circuit designs requiring component qualification documentation.

For Enhanced Thermal Performance: ERJ-2RKF2610X (Panasonic Electronic Components) provides upgraded 0.1W power rating with AEC-Q200 automotive qualification. This part is backward compatible with circuits designed for 0.063W operation and offers improved thermal margin in power-dissipation-sensitive applications.

Compliance Verification: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification matching the original RC1005F2610CS. Moisture sensitivity level remains at MSL 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-2610GLF replace RC1005F2610CS in all applications?

A: CR0402-FX-2610GLF provides direct electrical substitution with identical resistance, tolerance, power rating, and temperature specifications. The primary difference is the absence of documented moisture resistant features in the Bourns part specification. For applications where moisture resistance is not a design requirement, this part is fully compatible.

Q: What is the difference between the 0.063W and 0.1W power-rated substitutes?

A: ERJ-2RKF2610X is rated at 0.1W (1/10W) compared to the original 0.063W (1/16W) rating. This higher power rating provides greater thermal headroom and improved reliability in applications approaching the power dissipation limits of the original part. The 0.1W part is backward compatible with 0.063W-rated designs.

Q: Are AEC-Q200 qualified parts suitable for non-automotive applications?

A: CRCW0402261RFKED, RMCF0402FT261R, and ERJ-2RKF2610X all carry AEC-Q200 automotive qualification. These certifications indicate enhanced reliability testing and quality standards. These parts are suitable for any application and offer no disadvantage when used in non-automotive circuits.

Q: Does package size differ between substitute parts?

A: All substitute parts maintain the 0402 (1005 Metric) package format with identical physical dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm) and maximum seated height of 0.016" (0.40mm). No PCB layout modifications are required when substituting between these parts.

Q: What inventory considerations apply to these substitutes?

A: RC0402FR-07261RL (YAGEO) maintains the highest inventory level at 949,278 pieces. ERJ-2RKF2610X (Panasonic) provides 4,021,509 pieces. CRCW0402261RFKED (Vishay Dale) stocks 90,004 pieces. CR0402-FX-2610GLF (Bourns) has 45,717 pieces available. RMCF0402FT261R (Stackpole) maintains 1,045 pieces. Inventory levels should be verified at time of procurement.

Q: Are all substitutes ROHS3 compliant?

A: All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the environmental and regulatory compliance profile of the original RC1005F2610CS.
