LM336BZ50 Equivalent & Substitute Parts

Part Overview

The LM336BZ50 is a shunt voltage reference IC manufactured by onsemi, providing a fixed 5V output with ±2% tolerance in a TO-92-3 package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. Shunt voltage reference ICs are critical in precision analog circuits requiring stable reference voltages for comparators, analog-to-digital converters, and voltage regulation applications.

Substitute Part Grouping Explanation

Substitute parts for the LM336BZ50 are qualified based on the following critical parameters that determine functional equivalence:

• Reference Type: Shunt (identical across all parts)
• Output Type: Fixed (identical across all parts)
• Voltage - Output: 5V (identical across all parts)
• Tolerance: ±2% (identical across all parts)
• Operating Temperature Range: 0°C ~ 70°C (identical across all parts)
• Package / Case: TO-92-3 (identical across all parts)
• Mounting Type: Through Hole (identical across all parts)

The substitute parts LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB meet all critical electrical and mechanical parameters. Both are manufactured by National Semiconductor and share the same base product number (LM336), ensuring pin compatibility and functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB are qualified substitutes for the obsolete LM336BZ50. Selection between these two active alternatives should be based on the following factors:

LM336BZ-5.0/NOPB is supplied in bulk packaging and maintains full electrical and mechanical compatibility with the original part.

LM336Z-5.0/NOPB is available in higher inventory (30,909 pcs) and carries RoHS3 compliance certification in addition to REACH Unaffected status, providing additional regulatory assurance for applications requiring environmental compliance documentation.

Both parts share identical electrical specifications and TO-92-3 package geometry, ensuring direct pin-for-pin replacement in existing circuit designs. The difference in cathode current (600 µA vs. 10 mA) reflects manufacturing variations between National Semiconductor and onsemi but does not affect functional equivalence in standard shunt reference applications.

Frequently Asked Questions (FAQ)

Q: Can LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB be used interchangeably with LM336BZ50?

A: Yes. Both parts are pin-for-pin compatible and provide identical electrical performance. All three parts feature the same 5V fixed output, ±2% tolerance, and TO-92-3 package configuration.

Q: What is the difference between LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB?

A: Both parts are functionally equivalent. The primary differences are packaging designation (Bulk vs. standard) and regulatory certifications. LM336Z-5.0/NOPB includes RoHS3 compliance documentation.

Q: Why does the LM336BZ50 show 400 mA output current while the substitutes show 10 mA?

A: This reflects the maximum output current specification for each manufacturer's variant. In shunt reference applications, the actual operating current is determined by circuit design requirements and is typically much lower than the maximum rating.

Q: Are these parts suitable for new designs?

A: LM336BZ-5.0/NOPB and LM336Z-5.0/NOPB are both active products and are appropriate for new designs. The LM336BZ50 is obsolete and should not be specified for new applications.

Q: Do the substitute parts require any circuit modifications?

A: No. Both substitute parts maintain identical pin configuration and electrical specifications, allowing direct replacement without circuit redesign.
