LMF100CCN/NOPB Equivalent & Substitute Parts

Part Overview

The LMF100CCN/NOPB is a Universal Switched Capacitor Filter IC manufactured by Texas Instruments, designed for signal processing applications requiring 4th order filtering at 100kHz. This device integrates two independent filters in a 20-DIP through-hole package and operates across a 4V to 15V supply range.

The LMF100CCN/NOPB is classified as obsolete. Locating equivalent or substitute components is necessary for ongoing system support, maintenance, and new production builds where this part is specified in legacy designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LMF100CCN/NOPB is based on the following critical parameters:

• Package Compatibility: Both substitute parts maintain the 20-DIP (0.300", 7.62mm) through-hole form factor, ensuring mechanical and electrical pin compatibility
• Filter Architecture: All parts employ Universal Switched Capacitor topology with 4th order filtering and dual filter channels
• Mounting Type: Through-hole mounting is preserved across all alternatives
• Compliance Standards: RoHS3 compliance and MSL 1 rating are maintained

The substitute parts (LTC1060ACN#PBF and LTC1060CN#PBF) differ in cutoff frequency (30kHz versus 100kHz) and supply voltage range (±2.37V ~ 5V versus 4V ~ 15V). These differences require application-level evaluation to determine suitability for specific circuit implementations.

Parameter Comparison

Engineering Selection Recommendations

Both LTC1060ACN#PBF and LTC1060CN#PBF are active products from Analog Devices Inc., providing long-term availability and supply chain stability compared to the obsolete LMF100CCN/NOPB. Both substitute parts maintain full RoHS3 compliance and MSL 1 rating, meeting environmental and reliability standards.

The primary distinction between the two Analog Devices alternatives is packaging: LTC1060ACN#PBF is supplied in tube packaging, while LTC1060CN#PBF is also supplied in tube packaging. Both parts are functionally equivalent and differ only in cutoff frequency specification (30kHz) and supply voltage range (±2.37V ~ 5V) relative to the original part.

Selection between LTC1060ACN#PBF and LTC1060CN#PBF should be based on application-specific frequency requirements and power supply architecture compatibility.

Frequently Asked Questions (FAQ)

Q: Can LTC1060ACN#PBF or LTC1060CN#PBF be used as direct pin-for-pin replacements for LMF100CCN/NOPB?

A: Both substitute parts share the identical 20-DIP package footprint and pin count, enabling direct mechanical and electrical pin compatibility. However, the 30kHz cutoff frequency differs from the original 100kHz specification, requiring circuit-level evaluation to confirm functional compatibility with the intended application.

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

A: Both parts are functionally identical Universal Switched Capacitor Filter ICs with 4th order filtering, dual channels, and 30kHz cutoff frequency. The primary difference is packaging format; both are supplied in tube packaging. Selection between these two parts should be based on procurement and inventory requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both LTC1060ACN#PBF and LTC1060CN#PBF are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original LMF100CCN/NOPB.

Q: What supply voltage ranges do the substitute parts support?

A: The LTC1060ACN#PBF and LTC1060CN#PBF operate across ±2.37V ~ 5V, which differs from the original LMF100CCN/NOPB range of 4V ~ 15V. Applications requiring the higher voltage range of the original part may require power supply circuit modifications.

Q: Is the through-hole mounting type preserved in the substitute parts?

A: Yes. All substitute parts maintain through-hole mounting in the 20-DIP package format, preserving compatibility with existing PCB designs and assembly processes.
