Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM2907N is determined by strict equivalence across the following critical parameters:

• Functional Type: Frequency to Voltage Converter
• Frequency Range: 10 kHz maximum operating frequency
• Linearity Specification: ±0.3% accuracy
• Package Compatibility: 14-DIP (0.300", 7.62mm) through-hole mounting
• Pin Configuration: Identical pinout and electrical interface

The LM2907N/NOPB qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The LM2907N/NOPB is the direct equivalent for the obsolete LM2907N. Selection between these parts should be based on the following criteria:

For New Designs and Active Production: The LM2907N/NOPB is the appropriate choice. It maintains identical electrical performance and package specifications while offering active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

For Legacy System Maintenance: The LM2907N remains functionally equivalent where RoHS compliance is not a requirement. However, sourcing may be limited due to obsolete status.

Both parts share identical frequency response, linearity, and through-hole mounting characteristics, making them electrically interchangeable in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the LM2907N/NOPB be used as a direct replacement for the LM2907N?

A: Yes. The LM2907N/NOPB is electrically and mechanically identical to the LM2907N. Both devices operate at 10 kHz with ±0.3% linearity and use the same 14-DIP package. The primary difference is product status and RoHS compliance.

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

A: The "/NOPB" designation indicates the part is supplied in Tube packaging and is RoHS3 compliant. This is a packaging and compliance variant of the base LM2907 device.

Q: Are there any pin configuration differences between these parts?

A: No. Both the LM2907N and LM2907N/NOPB use identical 14-pin DIP configuration with the same pinout and electrical interface.

Q: What is the significance of the "Obsolete" status for the LM2907N?

A: Obsolete status indicates the part is no longer in active production. The LM2907N/NOPB, with Active status, is the recommended source for new procurement to ensure supply chain continuity.

Q: Are both parts suitable for through-hole PCB assembly?

A: Yes. Both parts are specified for through-hole mounting and use the standard 14-DIP (0.300", 7.62mm) package format compatible with conventional PCB assembly processes.

Q: What are the compliance differences between these parts?

A: The LM2907N is RoHS non-compliant, while the LM2907N/NOPB is ROHS3 compliant. Both are REACH Unaffected. For applications requiring RoHS compliance, the LM2907N/NOPB is the appropriate selection.
