Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2610CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 261 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (preferred for new designs)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (preferred)

All substitute parts listed below meet these mandatory electrical and mechanical parameters. Variations in physical dimensions (length, width, height) within standard 0603 package tolerances and differences in automotive qualification (AEC-Q200) or packaging format (Tape & Reel vs. Cut Tape) do not disqualify substitution eligibility but are noted for design consideration.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred for General Applications): RC0603FR-07261RL (YAGEO) is the primary direct equivalent to RC1608F2610CS. Both components share identical electrical specifications, operating temperature range, and ROHS3 compliance status. This part offers significantly higher inventory availability (91,981 units) and maintains the same non-automotive qualification profile as the original Samsung component.

Automotive-Qualified Alternatives (For AEC-Q200 Applications): When automotive-grade qualification is required, the following parts meet all electrical and mechanical parameters with AEC-Q200 certification:

• ERJ-3EKF2610V (Panasonic Electronic Components): Highest inventory availability among automotive-qualified options (89,386 units), ROHS3 compliant, identical physical dimensions to original part
• RMCF0603FT261R (Stackpole Electronics Inc): Largest inventory stock (114,873 units), ROHS3 compliant, AEC-Q200 rated
• CRCW0603261RFKEA (Vishay Dale): ROHS3 compliant, AEC-Q200 rated, 28,051 units available

Compliance Considerations: CRCW0603261RFKTA (Vishay Dale) meets all electrical and mechanical specifications but carries RoHS non-compliant status and REACH Affected designation. This part is suitable only for applications where RoHS3 compliance is not mandated.

Selection Logic:

• For direct replacement in non-automotive applications: RC0603FR-07261RL
• For automotive or high-reliability applications: ERJ-3EKF2610V or RMCF0603FT261R
• For maximum inventory availability: RMCF0603FT261R
• For legacy or non-compliant applications only: CRCW0603261RFKTA

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07261RL be used as a direct replacement for RC1608F2610CS? A: Yes. RC0603FR-07261RL is a direct equivalent. Both components have identical resistance value (261 Ohms), tolerance (±1%), power rating (0.1W), package format (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance status. Physical dimensions fall within standard 0603 package tolerances.

Q: What is the difference between automotive-qualified (AEC-Q200) and non-automotive versions? A: AEC-Q200 certification indicates the component has undergone additional qualification testing per automotive industry standards. The RC1608F2610CS is not AEC-Q200 qualified. Substitute parts with AEC-Q200 designation (AC0603FR-07261RL, ERJ-3EKF2610V, RMCF0603FG261R, RMCF0603FT261R, CRCW0603261RFKEA) meet the same electrical specifications but have additional automotive-grade reliability documentation. These are suitable for automotive applications but can also be used in non-automotive designs.

Q: Are there any physical dimension differences between substitute parts? A: Minor variations exist within standard 0603 package tolerances. The original RC1608F2610CS specifies 0.063" L x 0.031" W (1.60mm x 0.80mm) with 0.022" maximum seated height. CRCW0603261RFKEA and CRCW0603261RFKTA specify 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" maximum seated height. RMCF0603FG261R and RMCF0603FT261R specify 0.061" L x 0.031" W (1.55mm x 0.80mm). These variations are within standard 0603 package specifications and do not affect PCB footprint compatibility or electrical performance.

Q: Why is CRCW0603261RFKTA listed if it is RoHS non-compliant? A: CRCW0603261RFKTA meets all mandatory electrical and mechanical parameters (261 Ohms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). It is included for reference in applications where RoHS3 compliance is not required. For new designs or regulated applications, ROHS3-compliant alternatives are recommended.

Q: What is Moisture Sensitivity Level (MSL) 1, and why is it important? A: MSL 1 indicates unlimited shelf life without moisture-related degradation. All listed parts, including the original RC1608F2610CS, carry MSL 1 rating, meaning they do not require special moisture-control storage or handling procedures. This ensures compatibility across all substitute options.

Q: Can I use these substitute parts interchangeably on the same PCB assembly? A: Yes, all listed substitute parts are mechanically and electrically compatible with the RC1608F2610CS footprint and circuit requirements. They share identical 0603 package format, two-terminal configuration, and electrical specifications. Substitution can be performed at component procurement or assembly stage without PCB redesign.

Q: Which substitute part offers the best inventory availability? A: RMCF0603FT261R (Stackpole Electronics Inc) offers the highest inventory stock at 114,873 units. ERJ-3EKF2610V (Panasonic Electronic Components) is the second option with 89,386 units. Both are ROHS3 compliant and AEC-Q200 qualified.

Q: Are all substitute parts REACH compliant? A: Most substitute parts carry REACH Unaffected status. CRCW0603261RFKTA is marked as REACH Affected. For applications subject to REACH regulations, select from parts with REACH Unaffected designation: RC0603FR-07261RL, AC0603FR-07261RL, ERJ-3EKF2610V, RMCF0603FG261R, RMCF0603FT261R, or CRCW0603261RFKEA.
