WR06X2001FTL Equivalent & Substitute Parts

Part Overview

The WR06X2001FTL is a 2 kOhms ±1% 0.1W thick film chip resistor in 0603 (1608 Metric) surface mount package manufactured by Walsin Technology Corporation. This component is classified as Active product status and is RoHS3 compliant with REACH unaffected designation. Substitute parts are identified when original manufacturer inventory becomes unavailable, when design requirements mandate automotive-grade qualification, or when supply chain optimization necessitates alternative sourcing from qualified manufacturers offering equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WR06X2001FTL is determined by strict equivalence across the following parameters: resistance value (2 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH unaffected). All identified substitute parts meet these core electrical and mechanical requirements. The RMCF0603FT2K00 and ERJ-3EKF2001V are classified as direct equivalents with identical electrical specifications. Both substitute parts additionally carry AEC-Q200 automotive qualification, which represents an enhancement to the base specification rather than a deviation. Physical dimensions exhibit minor variations within acceptable tolerances for 0603 package class components. All substitute parts maintain identical termination count (2), moisture sensitivity level (1), and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The RMCF0603FT2K00 (Stackpole Electronics Inc) and ERJ-3EKF2001V (Panasonic Electronic Components) are direct functional equivalents to the WR06X2001FTL. Both substitute parts satisfy all electrical and mechanical requirements with identical resistance, tolerance, power rating, package configuration, and operating temperature specifications. The RMCF0603FT2K00 maintains the largest available inventory (1,154,320 pieces) and is suitable for general industrial applications. The ERJ-3EKF2001V provides AEC-Q200 automotive qualification and is appropriate for applications requiring automotive-grade component certification. Selection between these substitutes depends on application requirements and supply availability rather than electrical performance, as all three parts are functionally interchangeable within the specified parameters. Physical dimension variations (length and height) among the three parts remain within acceptable tolerances for 0603 package class components and do not affect circuit board layout or assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT2K00 be used as a direct replacement for WR06X2001FTL?

A: Yes. The RMCF0603FT2K00 meets all electrical specifications (2 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical requirements (0603 package, 2 terminations, RoHS3 compliant, MSL 1). The addition of AEC-Q200 automotive qualification does not prevent use in non-automotive applications.

Q: Can ERJ-3EKF2001V be used as a direct replacement for WR06X2001FTL?

A: Yes. The ERJ-3EKF2001V meets all electrical specifications (2 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical requirements (0603 package, 2 terminations, RoHS3 compliant, MSL 1). AEC-Q200 automotive qualification is an additional feature that does not affect compatibility.

Q: Are there physical dimension differences between these parts?

A: Minor variations exist within 0603 package class tolerances. WR06X2001FTL and ERJ-3EKF2001V both measure 0.063" L x 0.031" W (1.60mm x 0.80mm). RMCF0603FT2K00 measures 0.061" L x 0.031" W (1.55mm x 0.80mm). Height differences range from 0.022" to 0.024" maximum seated height. These variations are within standard 0603 package specifications and do not affect PCB layout or assembly compatibility.

Q: What is the difference between these parts in terms of compliance?

A: All three parts are RoHS3 compliant, REACH unaffected, and classified as EAR99 export control. RMCF0603FT2K00 and ERJ-3EKF2001V carry additional AEC-Q200 automotive qualification. WR06X2001FTL does not specify automotive qualification. This distinction affects application suitability but not electrical or mechanical compatibility.

Q: Which substitute part should be selected for automotive applications?

A: Both RMCF0603FT2K00 and ERJ-3EKF2001V carry AEC-Q200 automotive qualification and are suitable for automotive applications. Selection between these two depends on availability and supply chain requirements.

Q: Are all parts available in Tape & Reel packaging?

A: Yes. All three parts (WR06X2001FTL, RMCF0603FT2K00, and ERJ-3EKF2001V) are supplied in Tape & Reel (TR) packaging format.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.
