MPXQP15K Film Capacitor - Equivalent & Substitute Parts

Part Overview

The MPXQP15K is a 0.15 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) rated for 275V AC operation with polypropylene metallized dielectric. This component is designed for EMI and RFI suppression applications in through-hole configurations. The part is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance requirements. Substitute parts must maintain electrical performance and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPXQP15K is determined by strict equivalence across the following parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.15 µF
• Tolerance: ±10%
• Voltage rating (AC): 275V minimum
• Dielectric type: Polypropylene (PP), Metallized
• Mounting configuration: Through Hole, Radial
• Lead spacing: 0.591" (15.00mm)
• Ratings classification: X2

Acceptable Variation Parameters:

• Operating temperature range: Substitute must equal or exceed the -40°C to 100°C minimum range
• Physical dimensions: Minor variations acceptable if lead spacing and mounting type remain unchanged
• Product status: Substitute may have different status (Not For New Designs acceptable for legacy applications)

The ECQ-UAAF154K from Panasonic Electronic Components meets all mandatory matching criteria and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The ECQ-UAAF154K qualifies as a direct substitute for the obsolete MPXQP15K based on electrical and mechanical parameter equivalence. Selection criteria:

For Direct Replacement Applications: The ECQ-UAAF154K provides identical electrical performance with matching capacitance, voltage rating, tolerance, and dielectric properties. Lead spacing of 0.591" (15.00mm) ensures PCB footprint compatibility. The extended operating temperature range (-40°C to 110°C versus -40°C to 100°C) provides additional thermal margin.

Compliance Considerations: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production. ECCN and HTSUS classifications are identical, supporting supply chain documentation consistency.

Physical Compatibility: The ECQ-UAAF154K exhibits reduced physical dimensions (17.50mm x 6.00mm versus 18.00mm x 8.50mm) and lower seated height (13.50mm versus 15.00mm). These reductions present no functional impediment and may provide layout advantages in space-constrained applications. PCB hole spacing remains unchanged at 0.591" (15.00mm).

Product Status Consideration: The ECQ-UAAF154K carries "Not For New Designs" status. This designation does not preclude use in legacy system maintenance or production continuation of established products. Inventory availability (126,589 pieces) supports sustained supply for ongoing requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECQ-UAAF154K be used as a direct replacement for the MPXQP15K on existing PCBs?

A: Yes. The ECQ-UAAF154K maintains identical lead spacing (0.591" / 15.00mm), mounting type (through-hole radial), and electrical specifications (0.15 µF, ±10%, 275V AC, X2 rating). No PCB modification is required.

Q: What is the significance of the "Not For New Designs" status on the ECQ-UAAF154K?

A: This designation indicates the part is no longer recommended for new product development. However, it remains suitable for replacement in existing applications and production continuation of established products. The part maintains full compliance with ROHS3 and REACH requirements.

Q: Are there dimensional differences between the MPXQP15K and ECQ-UAAF154K?

A: Yes. The ECQ-UAAF154K is physically smaller: 17.50mm x 6.00mm versus 18.00mm x 8.50mm, with a lower seated height of 13.50mm versus 15.00mm. These reductions do not affect electrical performance or PCB compatibility, as lead spacing remains constant at 15.00mm.

Q: Does the ECQ-UAAF154K provide equivalent thermal performance?

A: The ECQ-UAAF154K operates across -40°C to 110°C, exceeding the MPXQP15K range of -40°C to 100°C. This extended upper temperature limit provides additional thermal margin in applications approaching the original component's maximum operating temperature.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the MPXQP15K and ECQ-UAAF154K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and supply.

Q: What is the lead spacing specification, and why is it critical for substitution?

A: Both components specify 0.591" (15.00mm) lead spacing. This dimension defines the PCB hole pattern and is critical for mechanical compatibility. Matching lead spacing ensures the substitute component fits existing PCB designs without modification.

Q: Can the ECQ-UAAF154K be used in EMI and RFI suppression applications?

A: Yes. The ECQ-UAAF154K is rated for EMI and RFI suppression with X2 classification, identical to the MPXQP15K. Both components are suitable for these applications.

Q: What inventory considerations apply to the ECQ-UAAF154K?

A: The ECQ-UAAF154K maintains substantial inventory availability (126,589 pieces new original in stock), supporting sustained supply for production and maintenance requirements. The MPXQP15K inventory is limited (669 pieces), making the substitute essential for long-term supply continuity.
