LINE FILTER 03DPCW5S Equivalent & Substitute Parts

Part Overview

The Delta Electronics 03DPCW5S is a single-phase EMC/EMI line filter rated for 115V/250VAC at 3A with 50/60Hz operation. This chassis-mount filter features two-stage configuration with wire lead termination, designed for general-purpose applications requiring electromagnetic compatibility filtering. The part maintains active product status with 713 units in current inventory. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across manufacturers while meeting identical or superior compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 03DPCW5S is determined by the following critical parameters:

• Filter Type & Configuration: Single-phase, two-stage topology
• Electrical Ratings: 3A current capacity with 110V–250VAC voltage range
• Operating Frequency: DC to 400Hz operational bandwidth encompasses the required 50/60Hz specification
• Mechanical Interface: Chassis mount with wire lead termination
• Compliance: ROHS3 compliance and REACH unaffected status required
• Regulatory Approvals: CSA, UR certifications as minimum baseline

The Schaffner EMC Inc. FN2070-3-07 meets all substitution criteria through equivalent electrical specifications, identical mechanical mounting, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 03DPCW5S (Delta Electronics)

Active product status with established supply chain. Holds CSA, UR, and VDE certifications. ROHS3 compliant with REACH unaffected designation. Current inventory of 713 units supports immediate procurement.

Substitute Part: FN2070-3-07 (Schaffner EMC Inc.)

Maintains active product status with 904 units in inventory. Electrical specifications are equivalent within the specified voltage and current parameters. Frequency operating range (DC ~ 400Hz) exceeds the 50/60Hz requirement. CSA and UR certifications align with primary part baseline. ROHS3 compliant with REACH unaffected status. Operating temperature specification (-25°C ~ 100°C) provides defined thermal performance envelope. Packaging format differs (tray versus box) but does not affect functional compatibility.

Both parts satisfy identical compliance and regulatory requirements for general-purpose EMC/EMI filtering applications in single-phase circuits.

Frequently Asked Questions (FAQ)

Q: What determines if FN2070-3-07 can replace 03DPCW5S?

A: Substitution is valid when filter type, configuration, current rating, mounting method, and termination style are identical. Both parts meet this requirement as single-phase, two-stage, 3A chassis-mount filters with wire leads. Voltage ratings (115V/250V versus 110V/250V) and frequency ranges (50/60Hz versus DC–400Hz) are compatible for general-purpose applications.

Q: Does the operating frequency difference affect substitution?

A: No. The FN2070-3-07 operates across DC to 400Hz, which encompasses the 50/60Hz requirement of the 03DPCW5S. Extended frequency capability does not compromise compatibility.

Q: Are the regulatory certifications equivalent?

A: Both parts hold CSA and UR certifications. The 03DPCW5S includes VDE certification while the FN2070-3-07 includes ENEC certification. Both maintain ROHS3 compliance and REACH unaffected status. Certification differences reflect regional approval pathways but do not indicate functional inequality.

Q: Does packaging format affect electrical performance?

A: No. The 03DPCW5S ships in box packaging while FN2070-3-07 ships in tray packaging. Packaging format is a logistics consideration only and does not alter electrical characteristics or mechanical fit.

Q: What is the significance of the 9.8mH inductance specification on the substitute part?

A: Inductance is a filtering characteristic that determines EMI attenuation performance. The FN2070-3-07 provides this specification while the 03DPCW5S does not. This documented inductance value supports design verification for applications with specific filtering requirements.

Q: Can I use FN2070-3-07 in applications rated for 115V if the substitute is rated 110V?

A: Yes. The 110V rating on the FN2070-3-07 accommodates standard North American line voltage tolerance (typically 110V ±10%). Both parts are rated for 250V operation, confirming dual-voltage capability across the specified range.
