Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMWA05P47M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 0.47 µF (exact match required)
• Capacitance tolerance: ±20% (exact match required)
• Voltage rating - DC: 50V (minimum requirement; higher ratings acceptable)
• Voltage rating - AC: 35V (minimum requirement; higher ratings acceptable)
• Dielectric material: Polyester, Metallized (exact match required)

Mechanical Parameters:

• Mounting type: Through Hole (exact match required)
• Package configuration: Axial (exact match required)
• Physical dimensions: 0.319" Dia × 0.685" L / 8.10mm × 17.40mm (exact match required)
• Termination style: PC Pins (exact match required)

Environmental Parameters:

• Operating temperature range: -55°C to 125°C (exact match required)

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation. Product status and regulatory compliance are secondary considerations that do not affect functional substitutability but influence procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

The MMWA05P47M-F is a parametric equivalent to the MMWA05P47M. Both components share identical electrical, mechanical, and environmental specifications, ensuring direct functional substitutability in circuit applications.

Key Differentiation Factors:

Product Status: The MMWA05P47M is classified as obsolete, while the MMWA05P47M-F maintains active product status. Active status indicates ongoing manufacturer support, continued availability, and compliance with current manufacturing standards.

Regulatory Compliance: The MMWA05P47M is RoHS non-compliant. The MMWA05P47M-F is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances directives. Selection of the MMWA05P47M-F is required for applications subject to RoHS3 regulatory requirements or for new designs requiring compliance certification.

Supply Availability: Both components are currently in stock. The MMWA05P47M has 940 units available; the MMWA05P47M-F has 682 units available. For long-term production continuity, the active status of MMWA05P47M-F provides greater assurance of sustained supply.

Selection Guidance: For legacy system maintenance or repair where RoHS compliance is not mandated, either component is functionally equivalent. For new designs, compliance-driven applications, or systems requiring long-term support, the MMWA05P47M-F is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the MMWA05P47M-F directly replace the MMWA05P47M in existing circuit designs?

A: Yes. The MMWA05P47M-F is a parametric equivalent with identical capacitance (0.47 µF), tolerance (±20%), voltage ratings (50V DC / 35V AC), dielectric material (polyester, metallized), physical dimensions (0.319" Dia × 0.685" L), and operating temperature range (-55°C to 125°C). Direct substitution is supported without circuit modification.

Q: What is the significance of the product status difference between these parts?

A: The MMWA05P47M is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The MMWA05P47M-F maintains active status, ensuring ongoing production, manufacturer support, and compliance with current standards. For applications requiring sustained supply or future design iterations, the active part is preferred.

Q: Does the RoHS3 compliance of MMWA05P47M-F affect electrical performance?

A: No. RoHS3 compliance relates to material composition and manufacturing processes, not electrical characteristics. Both components deliver identical electrical performance. RoHS3 compliance is a regulatory and procurement consideration, not a functional parameter.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both the MMWA05P47M and MMWA05P47M-F share identical axial package dimensions of 0.319" diameter × 0.685" length (8.10mm × 17.40mm). PCB layout and mechanical mounting are interchangeable.

Q: Which part should be selected for new product designs?

A: The MMWA05P47M-F is the appropriate selection for new designs. Active product status, ROHS3 compliance, and ongoing manufacturer support provide design continuity and regulatory alignment. The obsolete status of MMWA05P47M makes it unsuitable for new development.

Q: Are there any performance differences in operating temperature range?

A: No. Both components operate across the identical temperature range of -55°C to 125°C. Thermal performance and reliability characteristics are equivalent.
