LINE FILTER 03DRDG3S Equivalent & Substitute Parts

Part Overview

The Delta Electronics 03DRDG3S is a single-phase EMC/EMI line filter rated for 115V/250VAC at 3A, designed for general-purpose applications requiring electromagnetic compatibility filtering. This chassis-mount filter features a two-stage configuration with IEC 320-C14 and quick-connect termination options, operating across 50/60Hz frequencies. The product maintains active status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters align within the allowed specifications for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 03DRDG3S is determined by alignment of the following critical parameters:

• Filter Type & Configuration: Single-phase, two-stage topology
• Current Rating: 3 A nominal
• Frequency Support: 50/60Hz operation
• Mounting & Termination: Chassis mount with IEC 320-C14 and quick-connect compatibility
• Regulatory Compliance: CSA, UR, VDE approvals; RoHS3 compliance; REACH unaffected status
• Voltage Compatibility: Rated voltage must support the application requirements

The TE Connectivity Corcom Filters 6609031-7 qualifies as a substitute based on matching filter type, configuration, current rating, frequency support, mounting type, termination style, and regulatory compliance. Voltage rating differences and inductance variance are within acceptable substitution parameters for this product category.

Parameter Comparison

Engineering Selection Recommendations

Both the 03DRDG3S and 6609031-7 maintain active product status with identical regulatory certifications (CSA, UR, VDE) and RoHS3 compliance. Selection between these parts should be based on application voltage requirements: the 03DRDG3S supports dual-voltage operation (115V/250VAC), while the 6609031-7 is rated for 250VAC only. For applications operating exclusively at 250VAC, either part satisfies compliance and performance criteria. For applications requiring 115VAC operation, the 03DRDG3S is the appropriate selection. Inductance differences (2.8mH versus 4.62mH) reflect design variations between manufacturers and do not preclude substitution within the same application voltage class.

Frequently Asked Questions (FAQ)

Q: Can the 6609031-7 substitute for the 03DRDG3S in all applications?

A: Substitution is valid only for applications operating at 250VAC. The 6609031-7 is not rated for 115VAC operation. For dual-voltage or 115VAC-only applications, the 03DRDG3S must be used.

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

A: Inductance values (2.8mH versus 4.62mH) represent design variations in filter topology between manufacturers. Both values are within acceptable ranges for single-phase EMC/EMI filtering at 3A and do not affect substitution eligibility for equivalent voltage and current applications.

Q: Are the termination styles identical between these parts?

A: Yes. Both parts feature IEC 320-C14 connectors with quick-connect termination options, ensuring mechanical and electrical compatibility in chassis-mount installations.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the 03DRDG3S and 6609031-7 hold CSA, UR, and VDE approvals and are ROHS3 compliant with REACH unaffected status.

Q: What is the operating temperature range difference?

A: The 03DRDG3S operates from -25°C to 100°C, while the 6609031-7 operates from -10°C to 40°C. Application environment temperature requirements should be evaluated when selecting between these parts.

Q: Are packaging differences relevant to substitution?

A: Packaging format (Box versus Bulk) does not affect electrical or mechanical compatibility. Selection should be based on procurement and inventory requirements.
