Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 20DKBG5 are qualified based on the following electrical and mechanical parameters:

• Voltage Rating: All substitutes must support 250VAC minimum. The 20DKBG5 supports both 115V and 250VAC; substitutes rated for 250VAC are compatible with both voltage levels in the original specification.
• Current Rating: All substitutes must be rated for 20A.
• Filter Configuration: Single-phase, single-stage topology required.
• Mounting: Chassis mount required.
• Frequency Range: Operating frequency must encompass 50/60Hz.
• Regulatory Compliance: All substitutes must maintain ROHS3 compliance and possess equivalent or broader approval agency certifications.

The following parts meet these criteria:

• F1200AA20 (Curtis Industries): Direct substitute with Quick Connect termination
• FN2020-20-06 (Schaffner EMC Inc.): Similar substitute with extended frequency range (DC ~ 400Hz)
• F1200DD20 (Curtis Industries): Similar substitute with Threaded Post termination (alternative connection method)
• F1299AA20 (Curtis Industries): Similar substitute with Quick Connect termination

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Termination)

F1200AA20, FN2020-20-06, and F1299AA20 all feature quick-connect termination matching the 20DKBG5. These parts are suitable for direct replacement in applications where the existing connector interface is preserved. F1200AA20 and F1299AA20 are both Curtis Industries products with 50/60Hz operation. FN2020-20-06 offers extended frequency capability (DC ~ 400Hz), providing broader operational flexibility for applications requiring wider frequency support.

Alternative Termination Substitute

F1200DD20 uses threaded post (8-32) termination instead of quick connect. This part is suitable only when the application circuit design accommodates threaded post connection or when conversion hardware is available. Electrical and thermal ratings remain equivalent to the main part.

Regulatory Compliance

All substitute parts maintain ROHS3 compliance and active product status. F1200AA20 and F1200DD20 include CE and TUV certifications in addition to CSA and UR. FN2020-20-06 includes ENEC certification. The 20DKBG5 maintains VDE certification, which is present in F1299AA20 as well.

Frequently Asked Questions (FAQ)

Q: Can F1200DD20 be used as a direct replacement for 20DKBG5?

A: F1200DD20 is electrically equivalent but uses threaded post (8-32) termination instead of quick connect. Direct replacement requires either modification of the connection interface or use of appropriate adapter hardware. Electrical performance and current rating are identical.

Q: What is the difference between FN2020-20-06 and the other substitutes?

A: FN2020-20-06 operates across DC ~ 400Hz frequency range, compared to 50/60Hz for other parts. This extended frequency capability makes it suitable for applications requiring broader frequency support. All other electrical and mechanical parameters remain compatible.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts (F1200AA20, FN2020-20-06, F1200DD20, F1299AA20) are ROHS3 compliant, matching the compliance status of the 20DKBG5.

Q: Which substitute has the closest regulatory certification match to 20DKBG5?

A: F1299AA20 shares identical approval agencies (CSA, UR, VDE) with the 20DKBG5, making it the closest regulatory match. F1200AA20 and F1200DD20 include additional certifications (CE, TUV) beyond the original part.

Q: Can substitutes be used interchangeably in the same application?

A: F1200AA20, FN2020-20-06, and F1299AA20 are interchangeable when quick-connect termination is required. F1200DD20 requires circuit design accommodation for threaded post connection. All parts maintain 20A current rating and 250VAC voltage support.

Q: What inventory levels are available for each substitute?

A: F1200AA20: 638 units; FN2020-20-06: 1066 units; F1200DD20: 878 units; F1299AA20: 824 units. The main part 20DKBG5 has 900 units in stock.
