MF10ACN Equivalent & Substitute Parts

Part Overview

The MF10ACN is a Universal Switched Capacitor Filter IC manufactured by Texas Instruments, designed as a 4th Order 200kHz interface component in a 20-DIP package. This part operates with a dual supply voltage range of ±9V to ±14V and integrates two independent filters on a single die. The MF10ACN is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Substitute components must maintain functional equivalence in filter topology, package form factor, and pin configuration while accommodating different operating voltage specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF10ACN is based on strict equivalence of the following critical parameters:

Mandatory Equivalence Criteria:

• Filter topology: Universal Switched Capacitor architecture
• Filter order: 4th order configuration
• Number of independent filters: 2 filters per IC
• Package form factor: 20-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Pin configuration: 20-PDIP supplier package

Allowable Parameter Variations:

• Frequency - Cutoff or Center: The substitute parts operate at 30kHz, which differs from the original 200kHz specification. This variation is acceptable when the application circuit design accommodates the different clock frequency through appropriate external clock source adjustment.
• Voltage - Supply: Substitute parts operate at ±2.37V to ±5V, which is a narrower range than the original ±9V to ±14V specification. System power supply design must be verified for compatibility.
• Product Status: Substitutes are Active products, providing ongoing availability and support.
• RoHS Compliance: Substitute parts are ROHS3 Compliant, improving environmental and regulatory compliance compared to the non-compliant original.

The LTC1060ACN#PBF and LTC1060CN#PBF from Analog Devices Inc. meet all mandatory equivalence criteria and are qualified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MF10ACN is obsolete, while both LTC1060ACN#PBF and LTC1060CN#PBF are Active products. Active status ensures continued manufacturing, technical support, and long-term availability for production and field service applications.

Compliance and Certification: Both substitute parts are ROHS3 Compliant, meeting current environmental and regulatory requirements. The original MF10ACN is RoHS non-compliant, which may present restrictions in certain markets and applications subject to RoHS directives. Both substitutes maintain REACH Unaffected and EAR99 ECCN classifications, consistent with the original part.

Inventory Availability: LTC1060ACN#PBF has 3210 units in stock, while LTC1060CN#PBF has 871 units available. Both substitutes provide immediate procurement options compared to the obsolete MF10ACN.

Design Integration Requirements: System designs using the MF10ACN must be modified to accommodate the 30kHz operating frequency of the LTC1060 series, requiring adjustment of external clock source circuitry. Power supply design must be verified to operate within the ±2.37V to ±5V range of the substitute parts. Pin-for-pin compatibility in the 20-DIP package eliminates mechanical redesign requirements.

Frequently Asked Questions (FAQ)

Q: Are the LTC1060ACN#PBF and LTC1060CN#PBF pin-for-pin compatible with the MF10ACN?

A: Yes. Both substitute parts use the identical 20-DIP (0.300", 7.62mm) package with 20-PDIP pin configuration. Direct socket replacement is possible without PCB redesign.

Q: What is the primary difference between the MF10ACN and the LTC1060 substitutes?

A: The primary differences are operating frequency (200kHz vs. 30kHz) and supply voltage range (±9V~14V vs. ±2.37V~5V). Both maintain the same filter topology, order, and number of filters per IC.

Q: Can I use the LTC1060 series in a circuit designed for the MF10ACN without modifications?

A: No. The external clock frequency must be adjusted to accommodate the 30kHz operating frequency of the LTC1060 series. Additionally, power supply circuitry must be designed or modified to operate within the ±2.37V to ±5V range.

Q: What is the difference between LTC1060ACN#PBF and LTC1060CN#PBF?

A: Both parts are functionally equivalent with identical electrical specifications. The primary distinction is packaging format (Tube) and inventory availability. Selection between these two variants depends on procurement quantity requirements and packaging preferences.

Q: Is RoHS compliance a factor in selecting a substitute for the MF10ACN?

A: Yes. The MF10ACN is RoHS non-compliant, while both LTC1060 substitutes are ROHS3 Compliant. For applications subject to RoHS directives or customer requirements, the compliant substitutes are necessary.

Q: What is the moisture sensitivity level for these parts?

A: All three parts—MF10ACN, LTC1060ACN#PBF, and LTC1060CN#PBF—have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
