TE Connectivity Corcom Filters 3EYP LINE FILTER 250VAC 3A Equivalent & Substitute Parts

Part Overview

The TE Connectivity Corcom Filters 3EYP is a single phase EMC/EMI line filter rated for 250VAC at 3A with 50/60Hz operating frequency. This through-hole mounted filter is designed for general purpose applications and features PC pin termination. The product is currently active in production with 1099 pieces available in bulk packaging. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3EYP is determined by the following critical parameters that must align with the original specification:

Mandatory Matching Parameters:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage Rating: 250V AC
• Current Rating: 3 A
• Mounting Type: Through Hole
• Termination Style: PC Pins

Flexible Parameters (Allowable Variation):

• Operating Frequency: The 3EYP operates at 50/60Hz; substitutes with extended frequency ranges (DC ~ 400Hz) are compatible as they encompass the original operating band
• Inductance: Variation is acceptable within the context of EMI/EMI filtering performance; the 3EYP specifies 9.57mH while substitutes may differ
• Operating Temperature Range: Extended ranges provide enhanced operational capability
• Packaging: Bulk or Tray packaging does not affect electrical compatibility
• Approval Agencies: Substitutes must maintain equivalent safety certifications

The Schaffner EMC Inc. FN406-3-02 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity Corcom Filters 3EYP

The 3EYP remains the specified component for applications requiring the exact inductance value of 9.57mH and the specific operating temperature range of -10°C ~ 40°C. This part is active in production with established supply availability (1099 pieces in stock) and carries CSA, UR, and VDE approvals suitable for European and North American markets.

Substitute Part: Schaffner EMC Inc. FN406-3-02

The FN406-3-02 qualifies as a direct electrical substitute when the primary part is unavailable. This part maintains all critical electrical parameters: single phase, single stage configuration, 250V AC rating, and 3A current capacity with through-hole PC pin termination. The extended operating frequency range (DC ~ 400Hz) encompasses the original 50/60Hz specification. The broader operating temperature range (-25°C ~ 100°C) provides enhanced thermal capability. Both parts maintain ROHS3 compliance and share CSA and UR certifications. The FN406-3-02 offers superior inventory availability (3225 pieces in stock) and is packaged in trays for high-volume applications.

Key Consideration: The inductance difference (9.57mH versus 2.5mH) results in different EMI filtering characteristics. The FN406-3-02 provides lower inductance, which may affect attenuation performance at specific frequency bands. Selection between these parts should account for the filtering requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the Schaffner FN406-3-02 be used as a direct replacement for the TE Connectivity 3EYP in all applications?

A: The FN406-3-02 is electrically compatible for applications requiring 250VAC, 3A single phase EMI/EMI filtering with through-hole PC pin mounting. However, the inductance difference (2.5mH versus 9.57mH) means filtering performance characteristics differ. Applications with specific attenuation requirements at particular frequency bands should be evaluated against the filtering curves of each part.

Q: What is the significance of the operating frequency difference (50/60Hz versus DC ~ 400Hz)?

A: The 3EYP is specified for 50/60Hz operation. The FN406-3-02 operates across DC to 400Hz, which fully encompasses the original specification. This extended range indicates the FN406-3-02 can function in applications with variable frequency drives or broader frequency requirements without performance degradation at the original 50/60Hz band.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The 3EYP carries CSA, UR, and VDE approvals. The FN406-3-02 carries CSA, ENEC, and UR approvals. Both share CSA and UR certifications, which cover North American and international safety standards. The 3EYP includes VDE certification (European standard), while the FN406-3-02 includes ENEC certification (European standard). For applications requiring specific regional compliance, verify that the substitute meets the required certification standard.

Q: Does packaging format affect electrical performance?

A: No. The 3EYP is supplied in bulk packaging while the FN406-3-02 is supplied in tray packaging. Packaging format does not affect electrical characteristics, performance, or compatibility. Selection between bulk and tray packaging is based on procurement and inventory management requirements.

Q: What is the operating temperature impact when substituting?

A: The 3EYP operates from -10°C to 40°C. The FN406-3-02 operates from -25°C to 100°C. The substitute part supports a wider temperature range, making it suitable for applications with more extreme thermal environments. If the application operates within the original -10°C to 40°C range, both parts perform equivalently in this band.

Q: How do I determine which part to select for my application?

A: Use the 3EYP as the primary selection when available and when the 9.57mH inductance value is specified in the design. Switch to the FN406-3-02 when the primary part is unavailable, when extended frequency range capability is beneficial, or when the lower inductance value (2.5mH) is acceptable for the application's EMI filtering requirements. Verify that the substitute meets all regional compliance requirements for your market.
