Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LMC567CM/NOPB is determined by the following critical parameters:

Primary Compatibility Criteria:

• Identical function (Tone Decoder)
• Identical package type (8-SOIC with 0.154" width, 3.90mm)
• Identical mounting type (Surface Mount)
• Identical base product number (LM567 series)
• Identical number of circuits (1)
• Compliance with ROHS3 and REACH requirements

Electrical Parameter Compatibility:

• Supply voltage range must encompass or match the original specification (2V ~ 9V)
• Operating temperature range must support the application requirements
• Power consumption must be within acceptable limits for the application

Two substitute parts meet these criteria and are manufactured by Texas Instruments within the LM567 product family.

Engineering Selection Recommendations

LMC567CMX/NOPB is the primary recommended substitute for the obsolete LMC567CM/NOPB. This part maintains identical electrical specifications including the 2V to 9V supply voltage range, 500 mW power rating, and -25°C to 100°C operating temperature range. Both parts are LMCMOS™ series components with active product status, ensuring long-term availability and supply chain stability. The LMC567CMX/NOPB is available in Cut Tape and Digi-Reel packaging formats with 55,300 units in stock.

LM567CM/NOPB is an alternative substitute with active product status. This part operates within a narrower supply voltage range (4.75V to 9V) and narrower operating temperature range (0°C to 70°C) compared to the original specification. The LM567CM/NOPB also exhibits higher power consumption at 1.1 W. This substitute is suitable only for applications where the reduced voltage and temperature ranges are compatible with system requirements. The LM567CM/NOPB is available in Tube packaging with 2,250 units in stock.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Frequently Asked Questions (FAQ)

Q: Can LM567CM/NOPB replace LMC567CM/NOPB in all applications?

A: LM567CM/NOPB is a functional substitute but with electrical limitations. The reduced supply voltage range (4.75V to 9V versus 2V to 9V) and narrower operating temperature range (0°C to 70°C versus -25°C to 100°C) restrict its use to applications operating within these narrower specifications. Higher power consumption (1.1 W versus 500 mW) must also be considered in thermal design.

Q: Is LMC567CMX/NOPB a direct replacement for LMC567CM/NOPB?

A: Yes. LMC567CMX/NOPB maintains identical electrical and thermal specifications as the original LMC567CM/NOPB, including supply voltage range, power consumption, and operating temperature range. Both are LMCMOS™ series components. The primary difference is packaging format (Cut Tape & Digi-Reel versus standard packaging) and product status (Active versus Obsolete).

Q: What is the significance of the LMCMOS™ series designation?

A: LMCMOS™ is a Texas Instruments product series designation. Both LMC567CM/NOPB and LMC567CMX/NOPB carry this designation, indicating they share the same core technology and electrical characteristics. LM567CM/NOPB does not carry this designation.

Q: Are all three parts in the same 8-SOIC package?

A: Yes. All three parts use the 8-SOIC package with 0.154" width and 3.90mm dimensions. They are pin-compatible and suitable for identical PCB layouts.

Q: What are the compliance and regulatory differences between these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: Why is LMC567CM/NOPB marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The active status of LMC567CMX/NOPB and LM567CM/NOPB provides continuity for the LM567 tone decoder function.
