LINE FILTER 30TDS6D - Equivalent & Substitute Parts

Part Overview

The 30TDS6D is a three-phase (Delta) EMC/EMI line filter manufactured by Delta Electronics, rated for 30 A at 440VAC with 50/60Hz operation. This chassis-mount filter features a two-stage configuration with threaded post (M6) termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering in three-phase power systems.

The 30TDS6D maintains Active product status with 807 units in current inventory. Identifying equivalent substitute parts is necessary when supply constraints occur, when alternative sourcing is required for cost optimization, or when design flexibility permits component interchange within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 30TDS6D is determined by the following critical parameters:

• Filter Type: Must be Three Phase (Delta) configuration
• Voltage Rating: Must support 440V AC phase-to-phase operation
• Current Capacity: Must meet or exceed 30 A rating
• Mounting Type: Must be Chassis Mount compatible
• Frequency Compatibility: Must operate within 50/60Hz range
• Compliance: Must maintain ROHS3 compliance and REACH Unaffected status

The substitute part FN351-36-33 (Schaffner EMC Inc.) qualifies as an equivalent based on these parameters: it maintains three-phase (Delta) filter type, supports 440V phase-to-phase rating, provides 36 A current capacity (exceeding the 30 A requirement), utilizes chassis mount configuration, and operates across the DC ~ 60Hz frequency range. Both parts maintain ROHS3 compliance and REACH Unaffected status.

Parameter Comparison

Engineering Selection Recommendations

The 30TDS6D remains the primary selection for new designs due to its Active product status and current inventory availability (807 units in stock).

The FN351-36-33 qualifies as a functional equivalent for applications where the following conditions are met: the design accommodates terminal block termination in place of threaded post (M6) connection, the single-stage configuration meets EMI/EMC filtering requirements, and the Obsolete product status is acceptable for the application lifecycle. The FN351-36-33 provides higher current capacity (36 A versus 30 A) and extended frequency range (DC ~ 60Hz versus 50/60Hz), with CSA, ENEC, and UR approvals supporting broader regulatory acceptance.

Frequently Asked Questions (FAQ)

Q: Can FN351-36-33 directly replace 30TDS6D in existing installations?

A: Functional replacement is possible within the specified electrical parameters (440V, three-phase, 30+ A capacity). However, termination style differs: 30TDS6D uses threaded post (M6) while FN351-36-33 uses terminal block. Mechanical integration and connection methodology must be evaluated for each installation.

Q: What is the significance of the configuration difference (two-stage versus single-stage)?

A: Configuration affects filtering characteristics and attenuation performance. The 30TDS6D two-stage design provides different EMI/EMC filtering response compared to the FN351-36-33 single-stage design. Application-specific EMC requirements determine whether this difference is acceptable.

Q: Why is FN351-36-33 listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. While 1141 units remain in current inventory, long-term availability cannot be guaranteed. The Active status of 30TDS6D provides superior supply continuity for new designs.

Q: Are there compliance differences between these parts?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. FN351-36-33 carries additional approvals (CSA, ENEC, UR) not specified for 30TDS6D, which may be relevant for specific regulatory jurisdictions or application requirements.

Q: What inductance values apply to FN351-36-33?

A: Inductance specifications are not provided in the technical data for FN351-36-33. This parameter must be obtained from the manufacturer's detailed specifications if circuit design requires inductance matching or verification.
