Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10EK33 is determined by matching the following critical parameters:

• Single phase filter configuration
• 250VAC rated voltage
• 10A current rating
• 50/60Hz frequency operation
• Chassis mount mechanical form factor
• Wire lead termination style
• CSA, UR, and VDE regulatory approvals

The Curtis Industries F1299BB10 satisfies all these requirements and serves as a direct substitute. Both parts maintain identical electrical specifications and mechanical compatibility, with the primary distinction being product status and compliance certification level.

Parameter Comparison

Engineering Selection Recommendations

The F1299BB10 is the primary substitute for the obsolete 10EK33. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The F1299BB10 offers the advantage of active product status with current manufacturing support and improved RoHS3 compliance, making it the preferred selection for new designs and ongoing production requirements.

Selection between these parts should be based on inventory availability, lead time requirements, and compliance mandates specific to the application. The F1299BB10 provides superior long-term supply chain reliability due to its active status.

Frequently Asked Questions (FAQ)

Q: Can the F1299BB10 directly replace the 10EK33 in existing designs?

A: Yes. Both parts share identical electrical ratings (250VAC, 10A, 50/60Hz), filter configuration (single phase, single stage), and mechanical form factor (chassis mount, wire leads). Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between these parts?

A: The 10EK33 is obsolete with RoHS non-compliant status, while the F1299BB10 is an active product with ROHS3 compliance. Electrical and mechanical specifications are equivalent.

Q: Are regulatory approvals maintained across both parts?

A: Yes. Both the 10EK33 and F1299BB10 carry CSA, UR, and VDE approvals, ensuring compliance with the same regulatory standards.

Q: Does packaging differ between these parts?

A: The 10EK33 uses standard packaging, while the F1299BB10 is supplied in box packaging. This does not affect electrical or mechanical compatibility.

Q: What inventory status should be considered for procurement?

A: The 10EK33 has 694 pieces in stock as new original inventory. The F1299BB10 has 1000 pieces in stock as new original inventory. The F1299BB10 offers superior availability and active manufacturing support.
