LINE FILTER 20DBAS5 Equivalent & Substitute Parts

Part Overview

The Delta Electronics 20DBAS5 is a single-phase EMC/EMI line filter rated for 115V/250VAC at 20A with 50/60Hz operation. This chassis-mount filter features threaded post termination (8-32) and is designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production with 738 units in stock. Substitute parts are identified when equivalent electrical ratings, mechanical configurations, and regulatory approvals align with the original specification, enabling component interchangeability in system designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 20DBAS5 are classified based on electrical and mechanical parameter alignment:

Direct Manufacturer Substitute (851-20/011 by Qualtek): Maintains identical electrical specifications including 115V/250VAC dual voltage rating, 20A current capacity, 50/60Hz operation, 700µH inductance, and threaded post (8-32) termination. Operating temperature range differs (-25°C ~ 85°C versus -25°C ~ 100°C). Regulatory approvals (CSA, UR, VDE) are equivalent. This part qualifies as a direct substitute based on matching filter type, configuration, voltage, current, frequency, mounting, and termination parameters.

Similar Manufacturer Substitute (F1199AA20 by Curtis Industries): Maintains single-phase, single-stage configuration with 20A current rating and 50/60Hz operation. Voltage rating is 250VAC only (does not include 115V rating). Termination style differs (Quick Connect versus Threaded Post 8-32). Inductance value is not provided. Regulatory approvals differ (CE, CSA, TUV, UR versus CSA, UR, VDE). This part is classified as similar due to voltage rating limitation and termination incompatibility, requiring design verification for specific applications.

Parameter Comparison

Engineering Selection Recommendations

851-20/011 (Qualtek): This part is suitable as a direct substitute where the operating temperature maximum of 85°C meets application requirements. Both parts maintain CSA, UR, and VDE certifications and are ROHS3 compliant. Electrical parameters, mounting configuration, and termination style are identical. Selection is appropriate for applications operating within the 85°C thermal envelope.

F1199AA20 (Curtis Industries): This part is suitable only for applications requiring 250VAC operation exclusively (not dual 115V/250V). The Quick Connect termination requires mechanical redesign compared to threaded post mounting. Inductance specification is not provided, limiting direct performance comparison. Curtis Industries certification includes CE and TUV in addition to CSA and UR. Selection requires design modification and is limited to 250VAC-only system architectures.

Frequently Asked Questions (FAQ)

Q: Can 851-20/011 replace 20DBAS5 in all applications? A: The 851-20/011 is electrically and mechanically compatible with the 20DBAS5 for applications operating at or below 85°C. If your system operates above 85°C, the 20DBAS5 with its 100°C maximum rating is required.

Q: Why is F1199AA20 listed as a similar substitute rather than direct? A: The F1199AA20 has two limiting factors: it is rated for 250VAC only (lacks 115V capability), and it uses Quick Connect termination instead of threaded posts. These differences require mechanical redesign and limit its use to 250VAC-only applications.

Q: Are all three parts ROHS3 compliant? A: Yes, all three parts—20DBAS5, 851-20/011, and F1199AA20—are ROHS3 compliant and REACH unaffected.

Q: What is the significance of the 700µH inductance specification? A: The 700µH inductance value defines the filter's electromagnetic attenuation characteristics. The 20DBAS5 and 851-20/011 both specify 700µH, ensuring equivalent filtering performance. The F1199AA20 does not provide inductance data, preventing direct performance comparison.

Q: Do packaging differences affect substitution? A: Packaging (Bulk, Tray, Box) affects logistics and handling but does not impact electrical or mechanical compatibility. Component selection should prioritize electrical and mechanical parameters over packaging format.

Q: Which regulatory approvals are most critical for substitution? A: All three parts hold CSA and UR certifications. The 20DBAS5 and 851-20/011 share VDE approval, while F1199AA20 includes CE and TUV. Regulatory requirements depend on your target market and application standards.
