RCS3216F6490CS Equivalent & Substitute Parts

Part Overview

The RCS3216F6490CS is a 649 Ohm ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This component is classified as Active product status and features anti-sulfur and moisture-resistant construction. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in circuit designs without functional degradation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6490CS is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 649 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within the 1206 package envelope and differences in certifications (such as AEC-Q200 automotive qualification) do not preclude substitution, as these represent enhanced or alternative qualifications rather than functional deviations.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status, No Automotive Requirement): AC1206FR-07649RL (YAGEO) and RC1206FR-07649RL (YAGEO) are both Active status components with equivalent electrical and mechanical specifications to the RCS3216F6490CS. Both are ROHS3 compliant with MSL 1 rating. AC1206FR-07649RL includes AEC-Q200 automotive qualification, while RC1206FR-07649RL does not. Selection between these two depends on whether automotive-grade certification is required for the application.

Alternative Selection (Active Status, Automotive Requirement): CRCW1206649RFKEA (Vishay Dale) is an Active status component with AEC-Q200 automotive qualification. This part meets all electrical specifications and RoHS compliance requirements of the original component.

Secondary Selection (Active Status, General Purpose): CR1206-FX-6490ELF (Bourns Inc.) is an Active status component meeting all core electrical and mechanical specifications. This part does not carry automotive certification but is suitable for general industrial applications.

Not Recommended for New Designs: ERJ-8ENF6490V (Panasonic Electronic Components) carries a "Not For New Designs" product status designation. Although electrically and mechanically equivalent with AEC-Q200 certification, this part should not be selected for new circuit designs due to its obsolescence trajectory.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-07649RL replace RCS3216F6490CS in any application? A: Yes. AC1206FR-07649RL meets all electrical specifications (649 Ohms ±1%, 0.25W), operates across the same temperature range (-55°C ~ 155°C), and shares identical RoHS3 compliance and MSL 1 rating. Physical dimensions vary slightly within the 1206 package envelope but do not affect circuit performance or PCB layout compatibility.

Q: What is the difference between AC1206FR-07649RL and RC1206FR-07649RL? A: Both are YAGEO 1206 resistors with 649 Ohms ±1% specifications. AC1206FR-07649RL includes AEC-Q200 automotive qualification; RC1206FR-07649RL does not. Selection depends on whether automotive-grade certification is required. Electrical performance is identical.

Q: Why is ERJ-8ENF6490V marked "Not For New Designs"? A: This Panasonic component is electrically and mechanically equivalent but carries a "Not For New Designs" status, indicating the manufacturer is phasing out this product line. New circuit designs should select from Active status alternatives to ensure long-term component availability and supply chain stability.

Q: Does AEC-Q200 certification affect substitution eligibility? A: AEC-Q200 is an automotive qualification that represents enhanced testing and reliability standards. Parts with AEC-Q200 certification (AC1206FR-07649RL, CRCW1206649RFKEA, ERJ-8ENF6490V) are suitable replacements for non-automotive applications. However, if the original design does not require automotive qualification, non-certified alternatives (CR1206-FX-6490ELF, RC1206FR-07649RL) are equally valid from an electrical standpoint.

Q: Are physical dimension variations within the 1206 package critical? A: No. All substitute parts conform to the 1206 (3216 Metric) package standard. Minor variations in length (0.122" to 0.126"), width (0.063"), and height (0.024" to 0.030") fall within the package specification envelope and do not affect PCB footprint compatibility or circuit performance.

Q: Which substitute part has the highest inventory availability? A: ERJ-8ENF6490V (Panasonic) has 72,874 pieces in stock. However, due to its "Not For New Designs" status, AC1206FR-07649RL (YAGEO, 25,841 pieces) or CRCW1206649RFKEA (Vishay Dale, 25,247 pieces) are recommended for new designs with adequate inventory levels.
