LM336Z5 Equivalent & Substitute Parts

Part Overview

The LM336Z5 is a shunt voltage reference IC manufactured by onsemi, providing a fixed 5V output with ±4% tolerance in a TO-92-3 package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Shunt voltage references are critical in precision analog circuits requiring stable reference voltages for comparators, analog-to-digital converters, and voltage regulation circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM336Z5 is determined by the following critical parameters:

• Fixed 5V output voltage matching
• Shunt reference type and fixed output configuration
• TO-92-3 through-hole package compatibility
• Operating temperature range 0°C ~ 70°C
• RoHS3 compliance for regulatory alignment

The substitute parts identified (LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB) maintain the same base product family (LM336), output voltage, package type, and temperature range. These parts are manufactured by National Semiconductor and carry active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Both LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB are suitable substitutes for the obsolete LM336Z5 based on electrical and mechanical compatibility. The substitute parts offer improved tolerance (±2% versus ±4%), which provides tighter voltage regulation in precision applications.

LM336Z-5.0/NOPB is the preferred substitute due to explicit ROHS3 compliance certification, matching the regulatory status of the original part. This part maintains full compatibility with existing circuit designs while ensuring continued compliance with environmental and safety standards.

LM336BZ-5.0/NOPB is an alternative substitute with identical electrical specifications and package configuration. The bulk packaging option may be advantageous for high-volume production environments.

Frequently Asked Questions (FAQ)

Q: Can LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB be used interchangeably with LM336Z5?

A: Yes. Both substitute parts maintain the same 5V fixed output voltage, shunt reference type, TO-92-3 package, and 0°C ~ 70°C operating temperature range. The electrical and mechanical parameters align with the original part specifications.

Q: What is the difference between the two substitute parts?

A: LM336BZ-5.0/NOPB is supplied in bulk packaging, while LM336Z-5.0/NOPB packaging type is not specified. Both parts are electrically identical with ±2% tolerance and 10 mA output current. LM336Z-5.0/NOPB explicitly carries ROHS3 compliance certification.

Q: Why do the substitute parts have lower output current (10 mA vs. 15 mA)?

A: The substitute parts are rated for 10 mA output current, which is a specification difference from the original LM336Z5 (15 mA). Circuit designs must verify that the 10 mA rating is sufficient for the application's current requirements.

Q: Are there any compliance or certification differences?

A: LM336Z-5.0/NOPB carries explicit ROHS3 compliance and REACH Unaffected status. LM336BZ-5.0/NOPB compliance certifications are not specified in the available data. Both parts carry EAR99 ECCN classification and HTSUS code 8542.39.0001.

Q: What is the cathode current difference, and does it affect circuit design?

A: The original part specifies 10 mA cathode current, while substitutes specify 600 µA. This represents a significant reduction in minimum operating current, which may improve circuit efficiency and reduce power dissipation in applications with low bias current requirements.
