LINE FILTER 03DRCW5 - Equivalent & Substitute Parts

Part Overview

The Delta Electronics 03DRCW5 is a single-phase EMC/EMI line filter rated for 115V/250VAC at 3A with two-stage configuration and wire lead termination. This chassis-mount filter is designed for general-purpose applications requiring electromagnetic compatibility filtering across 50/60Hz operation. The part maintains active product status with 690 units in current inventory. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in applications where the original part becomes unavailable or when design flexibility permits alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 03DRCW5 are qualified based on the following critical parameters that determine functional equivalence:

• Filter Type & Configuration: Single Phase, Two Stage architecture
• Current Rating: 3 A nominal
• Voltage Compatibility: Minimum 250VAC rating (covers the 03DRCW5's 115V/250VAC dual rating)
• Mounting & Termination: Chassis Mount with Wire Leads
• Frequency Range: 50/60Hz operation minimum
• Regulatory Compliance: CSA, UR, VDE certifications

The identified substitutes (FN2060-3-07 and 3ER3) meet these core electrical and mechanical criteria, enabling direct replacement in applications where the 03DRCW5 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance. The 03DRCW5 and FN2060-3-07 share identical operating temperature ranges (-25°C ~ 100°C), providing thermal equivalence for demanding environments. The FN2060-3-07 offers extended frequency capability (DC ~ 400Hz) compared to the 03DRCW5's 50/60Hz specification, making it suitable for applications requiring broader frequency support. The 3ER3 operates within a narrower temperature window (-10°C ~ 40°C) and is therefore applicable only to applications within this thermal constraint. All three parts carry CSA and UR certifications; the FN2060-3-07 additionally holds CE and ENEC approvals. Inductance values vary (1.7mH, 4.62mH, 2.5mH respectively), which may influence filtering performance characteristics in specific circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the 3ER3 replace the 03DRCW5 in all applications?

A: The 3ER3 is electrically equivalent for 250VAC operation but operates within a restricted temperature range (-10°C ~ 40°C). It is suitable only for applications operating within this thermal window. The 03DRCW5's dual 115V/250VAC rating is not matched by the 3ER3, which is rated for 250VAC only.

Q: What is the significance of the inductance differences between these parts?

A: Inductance values (1.7mH, 4.62mH, 2.5mH) affect the filter's attenuation characteristics across the frequency spectrum. While all parts meet the core 50/60Hz requirement, circuit-specific filtering performance may vary. Verification against application-specific EMI/EMC requirements is necessary when substituting.

Q: Is the FN2060-3-07 compatible with 115VAC applications?

A: The FN2060-3-07 is rated for 250VAC only. Applications requiring 115VAC operation must use the 03DRCW5, which carries dual 115V/250VAC rating. The 3ER3 is also 250VAC-only.

Q: What packaging differences exist between these parts?

A: The 03DRCW5 is supplied in Box packaging, the 3ER3 in Bag packaging, and the FN2060-3-07 in Tray packaging. These packaging formats do not affect electrical or mechanical compatibility but may influence inventory handling and logistics considerations.

Q: Are all three parts certified for the same regulatory standards?

A: All three parts hold CSA and UR certifications. The 03DRCW5 and 3ER3 additionally carry VDE approval. The FN2060-3-07 holds CE, ENEC, and UR certifications in addition to CSA. Application-specific regulatory requirements determine which certifications are mandatory.
