F1700AA20 Equivalent & Substitute Parts

Part Overview

The F1700AA20 is a single-phase EMC/EMI line filter rated for 250VAC at 20A with 50/60Hz operation. Manufactured by Curtis Industries, this chassis-mount filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production status with 1031 units in stock.

Substitute parts become necessary when the F1700AA20 reaches end-of-life, when alternative sourcing is required for supply chain continuity, or when inventory constraints necessitate equivalent component selection. Substitute parts must maintain electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the F1700AA20 is determined by strict equivalence across the following critical parameters:

• Voltage rating: 250VAC (exact match required)
• Current capacity: 20A (exact match required)
• Operating frequency: 50/60Hz (exact match required)
• Filter topology: Single Phase, Single Stage configuration
• Mounting interface: Chassis Mount
• Termination interface: Quick Connect

The substitute part 20VDK1 manufactured by TE Connectivity Corcom Filters meets all electrical and mechanical compatibility criteria. This part maintains identical voltage, current, frequency, filter type, configuration, mounting type, and termination style specifications. Functional equivalence is established through these parameter matches.

Engineering Selection Recommendations

The F1700AA20 is the primary selection for new designs and applications requiring active production status and full manufacturer support. This part carries CE, CSA, TUV, and UR approvals and maintains ROHS3 compliance with REACH unaffected status.

The 20VDK1 serves as a functional equivalent for applications where the F1700AA20 becomes unavailable. However, the 20VDK1 carries obsolete product status and is manufactured by TE Connectivity Corcom Filters. This substitute maintains equivalent electrical performance and mechanical interface compatibility. The 20VDK1 holds CSA, UR, and VDE approvals with ROHS3 compliance, though REACH status is affected. Selection of the 20VDK1 should account for its obsolete classification and reduced manufacturer support availability.

Both parts are suitable for general-purpose EMC/EMI filtering applications in single-phase 250VAC, 20A systems operating at 50/60Hz.

Frequently Asked Questions (FAQ)

Q: Can the 20VDK1 directly replace the F1700AA20 in existing installations?

A: Yes. Both parts maintain identical electrical ratings (250VAC, 20A, 50/60Hz), filter configuration (single-phase, single-stage), mounting type (chassis mount), and termination interface (quick connect). Mechanical and electrical compatibility is established through these parameter matches.

Q: What is the significance of the 20VDK1 obsolete status?

A: Obsolete status indicates the 20VDK1 is no longer in active production. Existing inventory may be available, but manufacturer support and future availability cannot be guaranteed. The F1700AA20 remains the recommended choice for new applications due to its active production status.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant. The F1700AA20 carries CE, CSA, TUV, and UR approvals with REACH unaffected status. The 20VDK1 carries CSA, UR, and VDE approvals with REACH affected status. Application-specific compliance requirements should determine final part selection.

Q: What is the inductance specification, and why is it provided for only one part?

A: Inductance (540µH for the 20VDK1) is a filtering characteristic that affects EMI attenuation performance. The F1700AA20 inductance value was not provided in available specifications. Both parts function as equivalent filters for general-purpose applications; inductance differences do not affect basic substitution eligibility.

Q: Does operating temperature range affect substitution suitability?

A: The 20VDK1 specifies -10°C to 40°C operating range. The F1700AA20 operating temperature was not provided. For applications within the 20VDK1 specified range, both parts are functionally equivalent. Applications requiring extended temperature operation should reference the F1700AA20 manufacturer specifications.

Q: What packaging differences exist between these parts?

A: The F1700AA20 is supplied in box packaging, while the 20VDK1 is supplied in bulk packaging. Packaging does not affect electrical or mechanical compatibility; it reflects inventory and distribution practices only.
