MF100CCM Equivalent & Substitute Parts Reference

Part Overview

The MF100CCM is a low pass filter IC manufactured by Texas Instruments, designed for signal conditioning applications requiring 20kHz cutoff frequency with 2nd order filtering. This device is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. The MF100CCM operates on a 9V to 14V supply and is packaged in a 20-SOIC surface mount configuration with dual filter channels.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF100CCM are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts must use the 20-SOIC surface mount package to ensure PCB footprint compatibility without layout redesign.

Electrical Functionality: Substitute parts must provide dual-channel filtering capability with compatible frequency response characteristics. The MF100CCM operates with a 20kHz cutoff frequency; substitute parts with higher cutoff frequencies (30kHz) remain functionally suitable for applications where the original specification allows margin.

Supply Voltage: The MF100CCM requires 9V to 14V operation. Substitute parts with different supply voltage ranges require circuit redesign and are not direct pin-compatible replacements without additional power supply modifications.

Regulatory Compliance: All substitute parts must maintain ROHS3 compliance and EAR99 classification to ensure regulatory equivalence.

The LTC1060CSW family from Analog Devices Inc. qualifies as a substitute based on identical 20-SOIC packaging, dual-channel configuration, and compatible regulatory status. The LTC1060CSW operates as a universal switched capacitor filter with 4th order response and 30kHz cutoff frequency, providing enhanced filtering performance compared to the original 2nd order design.

Parameter Comparison

Engineering Selection Recommendations

The LTC1060CSW family represents the primary substitute option for the obsolete MF100CCM. All three variants (LTC1060CSW, LTC1060CSW#PBF, LTC1060CSW#TRPBF) maintain active product status with full ROHS3 compliance and improved moisture sensitivity ratings (MSL 1 versus MSL 3).

Critical Design Consideration: The LTC1060CSW operates on ±2.37V to 5V supply voltage, which differs significantly from the MF100CCM's 9V to 14V requirement. Direct substitution requires power supply circuit redesign and is not a pin-compatible replacement without additional engineering modifications.

Packaging Variants: LTC1060CSW#PBF is supplied in Tube packaging, while LTC1060CSW and LTC1060CSW#TRPBF do not specify packaging format. Selection between variants depends on procurement and assembly requirements rather than functional performance.

Inventory Availability: All LTC1060CSW variants maintain substantial stock levels (2000-2296 units), ensuring supply continuity for production applications.

Frequently Asked Questions (FAQ)

Q: Can the LTC1060CSW be used as a direct drop-in replacement for the MF100CCM?

A: No. While both devices share identical 20-SOIC packaging and dual-channel configuration, the LTC1060CSW requires ±2.37V to 5V supply voltage compared to the MF100CCM's 9V to 14V requirement. Circuit redesign is necessary to accommodate the different power supply specifications.

Q: What is the difference between LTC1060CSW, LTC1060CSW#PBF, and LTC1060CSW#TRPBF?

A: These are functionally identical parts with different packaging and tape/reel configurations. LTC1060CSW#PBF is supplied in Tube packaging. Selection depends on assembly and procurement requirements, not electrical performance.

Q: Why does the LTC1060CSW have a higher cutoff frequency (30kHz) than the MF100CCM (20kHz)?

A: The LTC1060CSW is a universal switched capacitor filter with 4th order response, compared to the MF100CCM's 2nd order low pass design. The higher cutoff frequency reflects the different filter architecture and provides enhanced filtering performance for compatible applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The MF100CCM and all LTC1060CSW variants maintain ROHS3 compliance, ensuring regulatory equivalence for applications requiring lead-free component specifications.

Q: What is the significance of the MSL rating difference?

A: The MF100CCM has MSL 3 (168 hours maximum floor life), while LTC1060CSW variants have MSL 1 (unlimited floor life). The improved MSL rating of substitute parts reduces moisture-related handling constraints during assembly and storage.
