MMWA2S33K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA2S33K-F is a 0.033 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), rated for 250V DC operation with polyester metallized dielectric construction. This component is designed for general-purpose applications requiring axial through-hole mounting. The part maintains Active product status with 810 units in current inventory stock.

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including capacitance value, voltage rating, dielectric material, and physical form factor. Substitution becomes necessary due to inventory availability, procurement lead times, or design revision requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMWA2S33K-F is determined by strict alignment with the following critical parameters:

Mandatory Match Criteria:

• Capacitance value: 0.033 µF (exact match required)
• Voltage rating: 250V DC minimum
• Dielectric type: Polyester, Metallized
• Mounting configuration: Through Hole Axial
• Termination style: PC Pins
• Regulatory compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: May vary (±10% to ±5%)
• AC voltage rating: May vary if DC rating is maintained
• Physical dimensions: May vary within PCB layout constraints
• Packaging format: May vary (Bulk vs. standard packaging)

The substitute part 150333J250BB meets all mandatory criteria while offering improved tolerance specification (±5% versus ±10%) and equivalent regulatory compliance.

Engineering Selection Recommendations

Primary Selection: MMWA2S33K-F

Use the MMWA2S33K-F when the original design specifications require the smaller physical envelope (5.00mm diameter x 14.30mm length). This part is ROHS3 compliant and maintains Active product status with adequate inventory availability (810 units in stock).

Substitute Selection: 150333J250BB

The 150333J250BB is electrically and functionally equivalent to the MMWA2S33K-F across all critical parameters. This substitute provides the following advantages:

• Tighter capacitance tolerance (±5% versus ±10%)
• Higher AC voltage rating (160V versus 125V)
• Greater inventory availability (1,306 units in stock)
• Identical DC voltage rating (250V)
• Identical dielectric material and operating temperature range
• Full ROHS3 compliance and REACH unaffected status

Physical Dimension Consideration:

The substitute part 150333J250BB has a larger physical footprint (6.00mm diameter x 16.50mm length versus 5.00mm x 14.30mm). PCB layout verification is required to confirm adequate clearance in the component mounting area before substitution.

Both parts are manufactured by Cornell Dubilier Electronics and carry identical regulatory certifications (ROHS3 Compliant, REACH Unaffected, ECCN EAR99).

Frequently Asked Questions (FAQ)

Q: Can 150333J250BB be used as a direct replacement for MMWA2S33K-F?

A: Yes, provided PCB layout accommodates the larger physical dimensions (6.00mm diameter x 16.50mm length versus 5.00mm x 14.30mm). All electrical parameters, voltage ratings, capacitance values, and regulatory certifications are equivalent or superior.

Q: What is the difference in tolerance between these parts?

A: The MMWA2S33K-F has ±10% tolerance, while the 150333J250BB has ±5% tolerance. The substitute offers tighter tolerance, which may improve circuit performance in applications sensitive to capacitance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both MMWA2S33K-F and 150333J250BB are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: What is the voltage rating difference?

A: Both parts are rated 250V DC. The AC voltage rating differs: MMWA2S33K-F is 125V AC, while 150333J250BB is 160V AC. For DC applications, this difference is not relevant.

Q: Will the larger size of 150333J250BB cause assembly issues?

A: The substitute is 1.00mm larger in diameter and 2.20mm longer. Verify PCB layout clearance around the component mounting location. Lead spacing and termination type (PC Pins) are identical, so assembly equipment compatibility is maintained.

Q: Are both parts currently in stock?

A: Yes. MMWA2S33K-F has 810 units in stock, and 150333J250BB has 1,306 units in stock, both listed as New Original inventory.

Q: Can I use these parts interchangeably in all applications?

A: Electrical interchangeability is confirmed. Physical interchangeability requires PCB layout verification due to dimensional differences. Both parts are suitable for general-purpose applications within the specified operating temperature range (-55°C to 125°C).
