Key Parameters

Substitute Part Grouping Explanation

Substitution of the 02ER33 is determined by strict equivalence across the following electrical and mechanical parameters:

• Single-phase filter topology
• Two-stage configuration
• 250VAC rated voltage
• 2A current rating
• 50/60Hz operating frequency
• Chassis mount form factor
• Wire lead termination

The Curtis Industries F1399BB02 satisfies all substitution criteria through identical electrical specifications and compatible mechanical interface. Both components maintain the same voltage, current, frequency, and physical mounting characteristics required for direct replacement in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The F1399BB02 provides direct electrical and mechanical equivalence to the 02ER33 across all critical filtering parameters. Selection of the F1399BB02 is supported by:

• Identical single-phase, two-stage filter topology
• Matching 250VAC, 2A, 50/60Hz electrical ratings
• Compatible chassis-mount and wire-lead interface
• Active product status ensuring ongoing availability
• Enhanced regulatory compliance through ROHS3 certification
• Expanded approval agency certifications including CE and TUV

The transition from 02ER33 to F1399BB02 maintains full functional equivalence while providing improved compliance posture for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the F1399BB02 directly replace the 02ER33 in existing applications?

A: Yes. Both components share identical electrical specifications (250VAC, 2A, 50/60Hz), filter configuration (single-phase, two-stage), and mechanical interface (chassis mount, wire leads). Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference?

A: The 02ER33 is obsolete, indicating discontinued manufacturing and limited availability. The F1399BB02 maintains active product status, ensuring reliable sourcing for current and future applications.

Q: How do the regulatory certifications differ?

A: The 02ER33 carries CSA, UR, and VDE approvals. The F1399BB02 expands this to include CE and TUV certifications, providing broader international regulatory recognition. Both maintain the core CSA and UR certifications required for North American applications.

Q: What is the RoHS compliance difference?

A: The 02ER33 is RoHS non-compliant. The F1399BB02 achieves ROHS3 compliance, meeting current environmental and material restriction requirements for electronic components in regulated markets.

Q: Are there packaging differences between these parts?

A: The 02ER33 uses standard packaging, while the F1399BB02 is supplied in box packaging. This does not affect electrical or mechanical compatibility.

Q: What inventory status should be considered?

A: The 02ER33 has 860 pieces in stock as new original inventory. The F1399BB02 has 803 pieces available. Both represent current stock positions; availability should be confirmed at time of procurement.
