Key Parameters

Substitute Part Grouping Explanation

Substitution of the 03EB33 is based on electrical and mechanical parameter equivalence. The Curtis Industries F1199BB03 qualifies as a direct substitute because it maintains identical specifications across all critical parameters: single phase filter type, single stage configuration, 250V AC rating, 3A current capacity, 50/60Hz frequency operation, chassis mount installation, and wire lead termination for general purpose applications.

The substitution logic is determined by the following key parameters:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage - Rated AC: 250V
• Current: 3 A
• Frequency - Operating: 50/60Hz
• Mounting Type: Chassis Mount
• Termination Style: Wire Leads

Parameter Comparison

Engineering Selection Recommendations

The F1199BB03 is the direct substitute for the obsolete 03EB33. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

The F1199BB03 offers additional advantages: active product status ensures ongoing availability and supply chain continuity, ROHS3 compliance meets current environmental regulations, and expanded approval certifications (CE, CSA, TUV, UR) provide broader regulatory acceptance compared to the 03EB33 (CSA, UR, VDE).

Frequently Asked Questions (FAQ)

Q: Can the F1199BB03 directly replace the 03EB33 in existing applications?

A: Yes. Both components are electrically and mechanically equivalent with identical ratings: 250VAC, 3A, single phase, single stage configuration, 50/60Hz operation, chassis mount, and wire lead termination.

Q: What is the difference in RoHS compliance between these parts?

A: The 03EB33 is RoHS non-compliant, while the F1199BB03 is ROHS3 compliant. For new designs or applications requiring environmental compliance, the F1199BB03 is the appropriate selection.

Q: Are the approval certifications compatible?

A: Both parts carry CSA and UR certifications. The F1199BB03 includes additional certifications (CE, TUV) that expand regulatory acceptance. The 03EB33 includes VDE certification. Verify specific certification requirements for your application.

Q: Is packaging different between these parts?

A: The 03EB33 packaging is listed as standard, while the F1199BB03 is supplied in a box. Confirm packaging requirements for your procurement and assembly processes.

Q: Why is the 03EB33 obsolete?

A: The 03EB33 has reached end-of-life status. The F1199BB03 from the active F1199 series is the current production equivalent.
