LINE FILTER 03DPDG3S Equivalent & Substitute Parts

Part Overview

The Delta Electronics 03DPDG3S is a single-phase EMC/EMI line filter rated for 3A at 115V and 250VAC, operating at 50/60Hz with two-stage filtering configuration. This chassis-mounted filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility and interference suppression. The part maintains active product status with full inventory availability and holds multiple international approvals including CSA, UR, and VDE certifications. Substitute parts are identified when equivalent electrical ratings, filtering characteristics, and mechanical mounting specifications align with the original component's functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 03DPDG3S is determined by the following critical parameters:

• Voltage Rating: Substitute must support 115V and 250VAC operation
• Current Capacity: Substitute must be rated for minimum 3A
• Filter Classification: Substitute must provide EMI/RFI filtering suitable for commercial or general-purpose applications
• Termination Method: Substitute must feature quick-connect termination compatible with 0.250" (6.3mm) blade configuration
• Mounting Configuration: Substitute must support chassis or bulkhead mounting
• Regulatory Compliance: Substitute must hold equivalent international approvals (CSA, UL, VDE, or equivalent)

The identified substitute part 3EP7 meets these criteria through equivalent current rating, voltage specification, filtered connector design, and quick-connect termination architecture.

Engineering Selection Recommendations

Primary Selection - 03DPDG3S: Recommended for new designs and applications requiring ROHS3 compliance. Maintains active manufacturing status with full inventory support and meets all specified regulatory requirements including CSA, UR, and VDE certifications.

Substitute Selection - 3EP7: Acceptable for retrofit or replacement applications where RoHS3 compliance is not mandated. The part provides equivalent electrical performance with 3A current capacity and 120/250VAC voltage rating. Holds active product status with CSA, UL, and VDE approvals. Note that RoHS non-compliance status requires verification against end-application regulatory requirements before implementation.

Both parts support 50/60Hz operation and feature quick-connect termination with 0.250" (6.3mm) blade configuration, ensuring mechanical and electrical compatibility within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the 3EP7 directly replace the 03DPDG3S in existing assemblies?

A: Electrical and mechanical compatibility is confirmed through matching current rating (3A), voltage specification (120/250VAC vs. 115V/250VAC), and quick-connect termination. However, RoHS compliance status differs. Verify end-application regulatory requirements before substitution.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer origin (Delta Electronics vs. TE Connectivity Corcom Filters), mounting configuration (chassis mount vs. bulkhead), and RoHS compliance status (ROHS3 compliant vs. non-compliant). Electrical performance and filtering characteristics remain equivalent.

Q: Are both parts suitable for 50/60Hz operation?

A: Yes. Both the 03DPDG3S and 3EP7 are rated for 50/60Hz operation and support the specified voltage and current parameters across this frequency range.

Q: What does the quick-connect termination specification mean?

A: Both parts feature 0.250" (6.3mm) quick-connect blade termination, enabling direct connection to standard power entry receptacles and filtered connector systems without soldering or crimping.

Q: Which part should be selected for new product designs?

A: The 03DPDG3S is the primary recommendation for new designs due to ROHS3 compliance status and active manufacturing support. The 3EP7 is suitable for legacy system replacements or applications where RoHS compliance is not required.
