Engineering Selection Recommendations

All substitute parts listed—160333K250C-F, B32529C3333K000, and B32529C3333K289—are Active products with ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the DME2S33K-F.

Electrical Compatibility: All substitute parts maintain identical capacitance (0.033 µF), tolerance (±10%), and voltage ratings (250V DC / 160V AC), ensuring direct electrical equivalence in circuit applications.

Physical Considerations: Dimensional variations exist among the substitute parts. The 160333K250C-F maintains similar overall dimensions to the DME2S33K-F with slightly different lead spacing (0.394" vs. 0.295"). The B32529C3333K000 and B32529C3333K289 employ a more compact stacked radial design with reduced footprint (7.30mm x 2.50mm vs. 10.30mm x 4.50mm) and tighter lead spacing (0.197" vs. 0.295"). Physical board layout compatibility must be verified before substitution.

Temperature Performance: The DME2S33K-F, B32529C3333K000, and B32529C3333K289 support the full -55°C to 125°C operating range. The 160333K250C-F operates to 105°C maximum, which may be limiting in high-temperature applications.

Packaging Format: The DME2S33K-F and 160333K250C-F are supplied in Bulk packaging. The B32529C3333K289 is supplied in Cut Tape (CT) format. The B32529C3333K000 is supplied in Bulk format. Packaging selection depends on assembly process requirements.

Application Suitability: The B32529C3333K000 and B32529C3333K289 carry AEC-Q200 automotive qualification and are rated for EMI/RFI suppression applications. The DME2S33K-F and 160333K250C-F are designated for general-purpose use.

Frequently Asked Questions (FAQ)

Q: Can the 160333K250C-F be used as a direct replacement for the DME2S33K-F?

A: The 160333K250C-F is electrically equivalent with matching capacitance, tolerance, and voltage ratings. However, physical dimensions differ: the 160333K250C-F is larger (0.512" L vs. 0.406" L) with different lead spacing (0.394" vs. 0.295"). Board layout compatibility must be confirmed. Additionally, the 160333K250C-F maximum operating temperature is 105°C compared to 125°C for the DME2S33K-F, which may be restrictive in high-temperature environments.

Q: Are the EPCOS B32529C3333K000 and B32529C3333K289 suitable replacements?

A: Both EPCOS parts are electrically equivalent and maintain the full -55°C to 125°C temperature range. However, they employ a compact stacked radial design with significantly smaller dimensions (7.30mm x 2.50mm vs. 10.30mm x 4.50mm) and tighter lead spacing (5.00mm vs. 7.50mm). These parts are suitable only if the application board layout accommodates the reduced footprint and lead spacing. The EPCOS parts carry AEC-Q200 automotive qualification, making them suitable for automotive and EMI/RFI suppression applications.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging is supplied as loose components suitable for manual assembly or bulk handling. Cut Tape (CT) packaging provides components on carrier tape in specified quantities, optimized for automated pick-and-place assembly equipment. Selection depends on manufacturing process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The DME2S33K-F, 160333K250C-F, B32529C3333K000, and B32529C3333K289 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Can I use a substitute part with a lower maximum operating temperature?

A: The 160333K250C-F operates to 105°C maximum, while the DME2S33K-F operates to 125°C. Substitution is permissible only if the application's actual operating temperature does not exceed 105°C. If the application requires operation above 105°C, the 160333K250C-F is not suitable.

Q: What are the key parameters that must match for substitution?

A: Electrical substitution requires matching capacitance (0.033 µF), tolerance (±10%), voltage ratings (250V DC / 160V AC), and dielectric material classification (polyester, metallized). Mechanical substitution requires compatible mounting type (through hole), package configuration (radial), and termination style (PC pins). Physical dimensions and lead spacing must be verified for board layout compatibility.
