MPXQP47K Film Capacitor 0.47µF 275VAC Equivalent & Substitute Parts

Part Overview

The MPXQP47K is a 0.47 µF film capacitor rated for 275V AC operation, manufactured by Cornell Dubilier Electronics (CDE) in the MPX series. This component is classified as obsolete product status, necessitating the identification of equivalent alternatives for continued system support and new production requirements. The part serves EMI and RFI suppression applications with X2 ratings and operates across the temperature range of -40°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPXQP47K is determined by matching the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Capacitance: 0.47 µF
• Tolerance: ±10%
• Voltage Rating - AC: 275V
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Package / Case: Radial
• Lead Spacing: 0.886" (22.50mm)
• Ratings: X2

The ECQ-UAAF474K from Panasonic Electronic Components meets these substitution criteria and is functionally equivalent for applications requiring these electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-UAAF474K provides electrical equivalence to the MPXQP47K and is ROHS3 compliant. Both parts share identical electrical specifications (capacitance, tolerance, voltage rating, dielectric material) and mechanical compatibility (identical lead spacing of 0.886 inches). The Panasonic substitute features an extended operating temperature range to 110°C, providing additional thermal headroom compared to the CDE original specification of 100°C. The ECQ-UAAF474K exhibits reduced physical dimensions (lower height and slightly reduced length) while maintaining the same lead spacing for direct pin-to-pin compatibility on PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-UAAF474K be used as a direct replacement for the MPXQP47K? A: Yes. Both parts share identical electrical specifications (0.47 µF, ±10% tolerance, 275V AC rating, polypropylene dielectric), identical lead spacing (0.886 inches), and both carry X2 ratings. The identical lead spacing permits direct board-level substitution.

Q: What are the physical differences between these parts? A: The ECQ-UAAF474K has a smaller footprint with reduced height (0.610" vs. 0.768") and slightly reduced length (1.024" vs. 1.043"). Lead spacing remains identical at 0.886 inches, ensuring PCB compatibility.

Q: What is the significance of the product status difference? A: The MPXQP47K is classified as obsolete, while the ECQ-UAAF474K carries a "Not For New Designs" designation. The latter remains available in inventory and is suitable for replacement applications and continued production support.

Q: Are there temperature rating considerations for substitution? A: The ECQ-UAAF474K supports an operating range of -40°C to 110°C, exceeding the MPXQP47K specification of -40°C to 100°C. For applications operating within the original -40°C to 100°C range, this provides additional thermal margin.

Q: Do both parts meet the same compliance standards? A: Both parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.
