LM2907M Frequency to Voltage Converter IC - Equivalent & Substitute Parts

Part Overview

The LM2907M is a Frequency to Voltage Converter IC manufactured by Texas Instruments, designed for applications requiring conversion of frequency signals up to 10 kHz into proportional voltage outputs. This component operates with ±0.3% linearity and is packaged in a 14-SOIC surface mount configuration.

The LM2907M is classified as Obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance of systems utilizing this frequency-to-voltage conversion function.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM2907M is determined by the following critical parameters:

• Base Product Number: LM2907 (all substitutes share this common base)
• Frequency - Max: 10 kHz (functional specification must match)
• Linearity: ±0.3% (accuracy specification must match)
• Mounting Type: Surface Mount (assembly compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirements)

Substitute parts are grouped based on package configuration. The LM2907M is available in two package variants: 14-SOIC and 8-SOIC. Both variants maintain identical electrical specifications and compliance certifications. Selection between variants depends on PCB layout requirements and pin count availability in the target application.

Parameter Comparison

Engineering Selection Recommendations

LM2907M/NOPB is the direct equivalent to LM2907M, maintaining identical package configuration (14-SOIC) and all electrical specifications. This part is classified as Active, providing improved supply chain availability compared to the Obsolete LM2907M. Both parts are ROHS3 Compliant and carry identical regulatory certifications.

LM2907M-8/NOPB provides functional equivalence with identical electrical performance but in an 8-SOIC package configuration. This variant is suitable for applications where PCB space constraints or pin count requirements favor the smaller package footprint. This part is also classified as Active.

Selection between the 14-SOIC and 8-SOIC variants depends solely on PCB layout requirements and application-specific pin availability. Both variants deliver equivalent frequency-to-voltage conversion performance and maintain full compliance with ROHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can LM2907M/NOPB directly replace LM2907M without PCB modifications?

A: Yes. LM2907M/NOPB is pin-compatible and functionally identical to LM2907M, both in 14-SOIC package configuration. No PCB layout changes are required.

Q: What is the difference between the 14-SOIC and 8-SOIC package variants?

A: The 14-SOIC variant (LM2907M/NOPB) and 8-SOIC variant (LM2907M-8/NOPB) differ only in package size and pin count. Electrical specifications, frequency range, linearity, and compliance certifications are identical. Package selection is determined by PCB design constraints and application requirements.

Q: Are all substitute parts ROHS3 Compliant?

A: Yes. LM2907M/NOPB and LM2907M-8/NOPB are both ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original LM2907M.

Q: Why is LM2907M marked as Obsolete while substitutes are Active?

A: Product status reflects current manufacturing and distribution status. Active parts indicate ongoing production and improved availability. Obsolete designation for LM2907M indicates discontinued production, making Active substitutes preferable for new designs and ongoing supply requirements.

Q: Can the 8-SOIC variant be used in applications originally designed for the 14-SOIC variant?

A: The 8-SOIC variant (LM2907M-8/NOPB) can be used only if the PCB layout accommodates the different package footprint and pin configuration. Electrical functionality is equivalent; however, physical layout compatibility must be verified before implementation.
