Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-6609021-3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Single-phase filter configuration
• Single-stage design
• 20A current rating
• 250VAC voltage compatibility
• 50/60Hz frequency operation
• Chassis mount installation
• General-purpose application suitability
• Active product status with current manufacturing support

Secondary Compatibility Factors:

• Regulatory approvals (CSA, UR, VDE certifications)
• RoHS3 compliance
• Operating temperature range
• Termination style compatibility with system design

Substitute parts must maintain the core electrical specifications (20A, 250VAC, 50/60Hz) and physical mounting requirements (chassis mount) to ensure functional equivalence. Variations in inductance, termination style, and operating temperature range are acceptable provided the substitute meets or exceeds the minimum requirements for the intended application.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1-6609021-3 (Primary Part)

Use this part for applications requiring the original specification with threaded post termination and the specified operating temperature range of -10°C to 40°C. This part maintains active production status with established supply availability.

SCHURTER 5500.2047 (Substitute)

This substitute is suitable for applications where quick-connect termination is acceptable and extended operating temperature range (-25°C to 100°C) is beneficial. The part supports dual voltage operation (125V/250VAC) and carries cURus, ENEC, and VDE approvals. The lower inductance value (150µH) differs from the original specification and must be evaluated for specific EMI/EMI filtering requirements. This part is active in production with 1117 units in stock.

Qualtek 851-20/011 (Substitute)

This substitute maintains threaded post (8-32) termination identical to the original part, supporting direct mechanical compatibility. The part supports dual voltage operation (115V/250VAC) and carries CSA, UR, and VDE approvals matching the original certification profile. The higher inductance value (700µH) differs from the original specification and must be evaluated for specific EMI/EMI filtering requirements. This part is active in production with 1065 units in stock.

All three parts are ROHS3 compliant and maintain active product status with current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 5500.2047 be used as a direct replacement for the TE Connectivity 1-6609021-3?

A: The SCHURTER 5500.2047 meets the core electrical requirements (20A, 250VAC, 50/60Hz, single-phase, single-stage, chassis mount). However, the termination style differs (quick connect versus threaded post 8-32), requiring mechanical interface verification. The inductance value is also lower (150µH versus 440µH), which affects filtering characteristics and must be evaluated for the specific application.

Q: Can the Qualtek 851-20/011 be used as a direct replacement for the TE Connectivity 1-6609021-3?

A: The Qualtek 851-20/011 meets the core electrical requirements (20A, 250VAC, 50/60Hz, single-phase, single-stage, chassis mount) and maintains identical termination style (threaded post 8-32). The inductance value is higher (700µH versus 440µH), which affects filtering characteristics and must be evaluated for the specific application.

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

A: Inductance is a key parameter in EMI/EMI filtering performance. The original part specifies 440µH, while substitutes offer 150µH (SCHURTER) and 700µH (Qualtek). These differences affect the filter's frequency response and attenuation characteristics. Selection must be based on the specific EMI/EMI filtering requirements of the target application.

Q: Are all three parts certified to the same regulatory standards?

A: All three parts carry VDE certification. The TE Connectivity and Qualtek parts share CSA and UR approvals. The SCHURTER part carries cURus and ENEC approvals instead. Regulatory compliance requirements for the specific application must be verified before substitution.

Q: What is the difference in operating temperature range between these parts?

A: The TE Connectivity part operates from -10°C to 40°C. Both substitute parts support extended ranges: SCHURTER from -25°C to 100°C and Qualtek from -25°C to 85°C. Applications operating outside the original temperature range may benefit from substitute parts with wider operating specifications.

Q: Does packaging format affect substitution?

A: The TE Connectivity part is supplied in bulk packaging, while the Qualtek part is supplied in tray packaging. The SCHURTER part is supplied in bulk packaging. Packaging format affects handling, storage, and integration into assembly processes but does not affect electrical or mechanical compatibility.

Q: Are all substitute parts currently in production?

A: Yes, all three parts maintain active product status with current manufacturing support. Inventory availability is confirmed: TE Connectivity 1-6609021-3 (916 units), SCHURTER 5500.2047 (1117 units), and Qualtek 851-20/011 (1065 units).
