MMWA05W2M Film Capacitor Equivalent & Substitute Parts

Part Overview

The MMWA05W2M is a 2 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE), designed for general-purpose applications requiring polyester metallized dielectric construction. This component features an axial through-hole mounting configuration with a 50V DC voltage rating and ±20% capacitance tolerance.

The MMWA05W2M carries an obsolete product status, making it necessary to identify active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility in existing circuit applications.

Electrical Parameters:

• Capacitance value: 2 µF
• Capacitance tolerance: ±20%
• Voltage rating (DC): 50V
• Voltage rating (AC): 35V
• Dielectric material: Polyester, Metallized

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: Axial
• Physical dimensions: 0.402" Dia x 1.248" L (10.20mm x 31.70mm)
• Termination style: PC Pins

Environmental Parameters:

• Operating temperature range: -55°C ~ 125°C

Substitute parts must match all parameters listed above. Product status and compliance certifications are secondary considerations that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MMWA05W2M-F serves as the direct parametric equivalent for the obsolete MMWA05W2M. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility in circuit applications.

The primary distinction between these parts is product status and regulatory compliance. The MMWA05W2M-F maintains active production status with ROHS3 compliance certification, whereas the MMWA05W2M is classified as obsolete and does not meet current RoHS requirements.

For new designs and production applications, the MMWA05W2M-F is the appropriate selection. For legacy system maintenance where the original MMWA05W2M is specified, the MMWA05W2M-F provides equivalent performance without requiring circuit redesign or validation.

Frequently Asked Questions (FAQ)

Q: Can MMWA05W2M-F be used as a direct replacement for MMWA05W2M?

A: Yes. The MMWA05W2M-F is a parametric equivalent with identical capacitance (2 µF), voltage ratings (50V DC / 35V AC), tolerance (±20%), dielectric material (polyester metallized), physical dimensions (0.402" Dia x 1.248" L), operating temperature range (-55°C ~ 125°C), and termination style (PC Pins axial). Direct substitution is supported without circuit modification.

Q: What is the difference between MMWA05W2M and MMWA05W2M-F?

A: The MMWA05W2M-F is the active production equivalent of the obsolete MMWA05W2M. Both parts are electrically and mechanically identical. The MMWA05W2M-F carries ROHS3 compliance certification, while the MMWA05W2M does not. The MMWA05W2M-F is recommended for all new applications.

Q: Are there any physical dimension differences between these parts?

A: No. Both the MMWA05W2M and MMWA05W2M-F share identical physical dimensions of 0.402" diameter by 1.248" length (10.20mm x 31.70mm). Axial lead spacing and PC pin termination are identical, ensuring compatibility with existing PCB layouts.

Q: What voltage ratings apply to these capacitors?

A: Both parts are rated for 50V DC and 35V AC operation. Component selection must ensure circuit voltage does not exceed these ratings under normal and fault conditions.

Q: What is the operating temperature range?

A: Both the MMWA05W2M and MMWA05W2M-F operate across -55°C to 125°C. Capacitance and performance specifications apply within this temperature envelope.

Q: Why is the MMWA05W2M classified as obsolete?

A: The MMWA05W2M has been discontinued by Cornell Dubilier Electronics. The MMWA05W2M-F represents the current production equivalent and is the recommended part for all new designs and procurement.
