MF10CCWMX Equivalent & Substitute Parts

Part Overview

The MF10CCWMX is a Universal Switched Capacitor Filter IC designed for signal processing applications requiring precise frequency filtering. This 4th order filter operates at a center frequency of 200kHz and integrates two independent filter channels in a compact 20-SOIC surface mount package. The main part number MF10CCWMX is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF10CCWMX is determined by strict equivalence across the following electrical and mechanical parameters:

• Filter topology and order (Universal Switched Capacitor, 4th order)
• Operating frequency (200kHz center/cutoff)
• Number of integrated filter channels (2)
• Supply voltage range (±9V ~ 14V)
• Physical package specification (20-SOIC with 0.295" / 7.50mm width)
• Pin-to-pin compatibility within the 20-SOIC footprint

The MF10CCWMX/NOPB variant qualifies as a direct substitute because it maintains identical electrical specifications and mechanical compatibility while offering active product status and improved compliance certifications.

Engineering Selection Recommendations

The MF10CCWMX/NOPB is the direct functional equivalent of the obsolete MF10CCWMX. Selection between these parts is determined by application requirements and regulatory compliance:

• For new designs and production environments requiring RoHS3 compliance, the MF10CCWMX/NOPB is the appropriate choice.
• The MF10CCWMX/NOPB maintains active product status with established supply chain availability, reducing long-term procurement risk.
• Both parts share identical electrical performance and mechanical compatibility, ensuring drop-in replacement capability.
• The MF10CCWMX/NOPB offers improved moisture sensitivity classification (MSL 3 vs. MSL 2A), providing extended handling windows in manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can MF10CCWMX/NOPB replace MF10CCWMX in existing designs?

A: Yes. The MF10CCWMX/NOPB is electrically and mechanically identical to the MF10CCWMX. Pin configuration, electrical specifications, and package dimensions are equivalent, enabling direct substitution without circuit modification.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" designation indicates the part is supplied without lead (Pb), reflecting RoHS3 compliance. This is a packaging and compliance variant of the base MF10CCWMX design.

Q: Are there differences in handling or storage between these parts?

A: The MF10CCWMX/NOPB has an MSL rating of 3 (168 hours), compared to MSL 2A (4 weeks) for the MF10CCWMX. This provides a longer moisture absorption window before reflow soldering, reducing bake-out requirements in high-humidity manufacturing environments.

Q: Is the MF10CCWMX still available for purchase?

A: The MF10CCWMX is classified as obsolete. The MF10CCWMX/NOPB is the active equivalent with established supply chain availability.

Q: What are the key electrical parameters that define substitution for this filter IC?

A: Substitution is determined by matching filter topology (Universal Switched Capacitor), filter order (4th), center frequency (200kHz), number of channels (2), supply voltage range (±9V ~ 14V), and package type (20-SOIC). All these parameters are identical between the MF10CCWMX and MF10CCWMX/NOPB.
