MMWA2P33K Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA2P33K is a 0.33 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating and ±10% tolerance. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement requirements. The part features polyester metallized dielectric construction in an axial through-hole package suitable for general-purpose applications.

Substitute Part Grouping Explanation

Substitution of the MMWA2P33K is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 0.33 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 250V (minimum requirement)
• Dielectric Material: Polyester, Metallized (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Axial (exact match required)
• Termination: PC Pins (exact match required)

Substitute parts are classified into two categories:

Direct Equivalent: Parts that maintain identical electrical and mechanical specifications while offering improved product status or compliance certifications.

Similar Equivalent: Parts that maintain core electrical specifications (capacitance, tolerance, DC voltage rating, dielectric material, temperature range, mounting, and termination) but may exhibit variations in physical dimensions or AC voltage rating within acceptable design parameters.

Engineering Selection Recommendations

MMWA2P33K-F (Direct Equivalent - Recommended Primary Substitute)

The MMWA2P33K-F is the direct equivalent substitute for the obsolete MMWA2P33K. This part maintains identical electrical specifications and physical dimensions while offering active product status and ROHS3 compliance. The MMWA2P33K-F is manufactured by the same supplier (Cornell Dubilier Electronics) within the same MMWA series. Selection of this part eliminates obsolescence risk and provides compliance with current regulatory requirements.

150334K250FC (Similar Equivalent - Secondary Substitute)

The 150334K250FC is a similar equivalent substitute that maintains all critical electrical parameters: 0.33 µF capacitance, ±10% tolerance, 250V DC rating, polyester metallized dielectric, -55°C to 125°C operating range, through-hole axial mounting, and PC pin termination. This part differs in physical dimensions (0.335" Dia x 0.807" L versus 0.366" Dia x 0.728" L) and AC voltage rating (160V versus 125V). The 150334K250FC is manufactured by Cornell Dubilier Electronics in the 150 series and carries active product status with ROHS3 compliance. Physical dimension differences require verification of board layout compatibility prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can MMWA2P33K-F be used as a direct replacement for MMWA2P33K?

A: Yes. The MMWA2P33K-F is a direct equivalent substitute. Both parts share identical capacitance (0.33 µF), tolerance (±10%), voltage ratings (125V AC / 250V DC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), mounting type (through hole), package type (axial), physical dimensions (0.366" Dia x 0.728" L), and termination (PC pins). The primary difference is product status: MMWA2P33K-F is active while MMWA2P33K is obsolete.

Q: What are the key differences between MMWA2P33K-F and 150334K250FC?

A: Both parts maintain equivalent capacitance, tolerance, DC voltage rating, dielectric material, operating temperature range, mounting type, package type, and termination. The 150334K250FC differs in two parameters: AC voltage rating (160V versus 125V) and physical dimensions (0.335" Dia x 0.807" L versus 0.366" Dia x 0.728" L). These differences require evaluation of circuit requirements and PCB layout constraints.

Q: Are there compliance differences between the substitute parts?

A: Yes. The MMWA2P33K is RoHS non-compliant, while both MMWA2P33K-F and 150334K250FC are ROHS3 compliant. All three parts maintain REACH Unaffected status and EAR99 export classification. Selection of compliant substitutes aligns with current regulatory requirements.

Q: Does physical dimension variation affect circuit performance?

A: Physical dimensions do not affect electrical performance. However, dimensional differences between MMWA2P33K (0.366" Dia x 0.728" L) and 150334K250FC (0.335" Dia x 0.807" L) require verification of PCB layout compatibility, including lead hole spacing and component clearance requirements.

Q: What is the significance of the AC voltage rating difference?

A: The MMWA2P33K and MMWA2P33K-F both carry 125V AC rating, while 150334K250FC carries 160V AC rating. All three parts maintain 250V DC rating. AC voltage rating selection depends on circuit application requirements. The higher AC rating of 150334K250FC provides additional margin in AC applications.

Q: Are all substitute parts available in equivalent quantities?

A: Inventory availability differs among parts. MMWA2P33K has 680 pieces in stock (obsolete status). MMWA2P33K-F has 1097 pieces in stock (active status). 150334K250FC has 1039 pieces in stock (active status). Procurement decisions should account for current inventory levels and supply chain continuity.
