TE Connectivity Corcom Filters 3EH3 LINE FILTER 250VAC 3A CHASSIS

Part Overview

The TE Connectivity Corcom Filters 3EH3 is a single-phase EMC/EMI line filter rated for 250VAC at 3A with 50/60Hz operating frequency. This chassis-mounted filter features wire lead termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering. The product is currently active in production with 1164 units in stock. Alternative models may be required due to inventory constraints, specific frequency range requirements, or operational temperature specifications for particular application environments.

Key Parameters

Substitute Part Grouping Explanation

The Schaffner EMC Inc. FN2010B-3-07 qualifies as a substitute for the TE Connectivity Corcom Filters 3EH3 based on the following critical parameters:

Matching Parameters:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage - Rated AC: 250V
• Current Rating: 3 A
• Mounting Type: Chassis Mount
• Termination Style: Wire Leads
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Differing Parameters:

• Frequency - Operating: DC ~ 400Hz (versus 50/60Hz)
• Operating Temperature: -25°C ~ 100°C (versus -10°C ~ 40°C)
• Inductance: 2.5mH (versus 1mH)
• Approval Agencies: CSA, ENEC, UR (versus CSA, UR, VDE)
• Packaging: Tray (versus Bulk)

The FN2010B-3-07 maintains electrical and mechanical compatibility through identical voltage, current, and mounting specifications. The extended frequency range and operating temperature range of the substitute part provide broader application flexibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity Corcom Filters 3EH3 and Schaffner EMC Inc. FN2010B-3-07 are active products with ROHS3 compliance and appropriate regulatory certifications for general-purpose applications.

Selection Criteria:

The 3EH3 is suitable for applications operating within the 50/60Hz frequency band and -10°C to 40°C temperature range with VDE certification requirements.

The FN2010B-3-07 is suitable for applications requiring extended frequency operation (DC to 400Hz) and broader temperature range (-25°C to 100°C) with ENEC certification. The higher inductance value (2.5mH versus 1mH) may affect filtering characteristics and should be evaluated against specific EMI/EMC requirements.

Both parts maintain identical voltage, current, mounting, and termination specifications, ensuring mechanical and electrical interchangeability within their respective operational parameters.

Frequently Asked Questions (FAQ)

Q: Can the FN2010B-3-07 directly replace the 3EH3 in all applications?

A: The FN2010B-3-07 maintains electrical and mechanical compatibility through matching voltage, current, mounting, and termination specifications. However, the higher inductance (2.5mH versus 1mH) and extended frequency range (DC ~ 400Hz versus 50/60Hz) may alter filtering performance. Application-specific EMI/EMC requirements must be evaluated.

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

A: The 3EH3 has 1mH inductance while the FN2010B-3-07 has 2.5mH inductance. Inductance affects the filter's frequency response and attenuation characteristics. Higher inductance typically provides greater attenuation at higher frequencies but may introduce different impedance characteristics in the circuit.

Q: Are there packaging differences between these parts?

A: Yes. The 3EH3 is supplied in Bulk packaging, while the FN2010B-3-07 is supplied in Tray packaging. This affects handling, storage, and integration into manufacturing processes but does not impact electrical or mechanical performance.

Q: Which certifications are critical for my application?

A: The 3EH3 carries CSA, UR, and VDE approvals. The FN2010B-3-07 carries CSA, ENEC, and UR approvals. Verify that the required certifications for your specific application and geographic market are present on the selected part.

Q: What is the operating temperature range difference?

A: The 3EH3 operates from -10°C to 40°C, while the FN2010B-3-07 operates from -25°C to 100°C. The substitute part accommodates a significantly wider temperature range, making it suitable for more demanding thermal environments.

Q: Can I use the FN2010B-3-07 in a 50/60Hz application?

A: Yes. The FN2010B-3-07 frequency range of DC ~ 400Hz encompasses 50/60Hz operation. The part is fully compatible with standard AC power line frequencies.
