NE567V Equivalent & Substitute Parts

Part Overview

The NE567V is a telecom interface integrated circuit functioning as a tone decoder in 8-PDIP packaging. Manufactured by Texas Instruments, this component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and production continuity. The NE567V operates within a 4.75V to 9V supply range and is designed for through-hole mounting applications requiring tone detection functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NE567V is determined by the following critical parameters:

• Functional equivalence: Both parts must perform tone decoder functionality
• Package compatibility: Identical 8-DIP (0.300", 7.62mm) through-hole package required for direct PCB mounting without redesign
• Electrical specifications: Supply voltage range (4.75V ~ 9V) and operating temperature range (0°C ~ 70°C) must be maintained or exceeded
• Pin configuration: Identical pin count and signal assignment in 8-pin DIP format
• Manufacturer continuity: Texas Instruments as original manufacturer ensures design consistency and documentation alignment

The LM567CN/NOPB qualifies as a direct substitute based on these parameters. Both components share identical package specifications, functional purpose, voltage operating range, and temperature specifications, enabling direct replacement in existing designs.

Engineering Selection Recommendations

The LM567CN/NOPB is the direct equivalent for NE567V replacement. Selection is based on the following engineering criteria:

Product Status: The NE567V is obsolete, while the LM567CN/NOPB maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: The LM567CN/NOPB is ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and distribution. The NE567V is RoHS non-compliant, which may restrict use in regulated markets and applications.

Electrical Compatibility: Both components operate within identical voltage supply ranges (4.75V ~ 9V) and temperature specifications (0°C ~ 70°C). The LM567CN/NOPB exhibits higher supply current (12mA versus 6mA), which must be verified against power supply capacity in the target application.

Physical Compatibility: Identical 8-DIP package specifications enable direct PCB mounting without layout modifications or redesign.

Certification Alignment: Both components share identical REACH and ECCN classifications, maintaining regulatory consistency across supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the LM567CN/NOPB be used as a direct replacement for NE567V without PCB modifications?

A: Yes. Both components use identical 8-DIP (0.300", 7.62mm) through-hole packaging with matching pin configurations. Direct substitution on existing PCBs is possible without layout changes.

Q: What is the primary difference between NE567V and LM567CN/NOPB?

A: The NE567V is obsolete with RoHS non-compliant status, while the LM567CN/NOPB is an active product with ROHS3 compliance. The LM567CN/NOPB also specifies higher supply current (12mA versus 6mA).

Q: Does the higher supply current of LM567CN/NOPB affect circuit design?

A: The increased current specification (12mA versus 6mA) must be verified against the power supply capacity of the target application. Existing power supply designs rated for 6mA minimum should be evaluated for the 12mA requirement.

Q: Are there any compliance considerations when switching from NE567V to LM567CN/NOPB?

A: The LM567CN/NOPB is ROHS3 compliant, whereas the NE567V is RoHS non-compliant. Applications subject to RoHS regulations should transition to the LM567CN/NOPB to maintain compliance.

Q: What packaging options are available for the LM567CN/NOPB?

A: The LM567CN/NOPB is supplied in tube packaging. The NE567V was supplied without specified packaging format. Both maintain identical component specifications within the 8-DIP package.

Q: Are pin assignments identical between NE567V and LM567CN/NOPB?

A: Yes. Both components are 8-pin DIP devices with identical functional pin assignments for tone decoder operation, enabling direct circuit substitution.
