LM236H-5.0 Equivalent & Substitute Parts

Part Overview

The LM236H-5.0 is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision 5V fixed output applications. This active product operates as a shunt regulator with ±2% output tolerance and supports 10 mA output current in a TO-46-3 metal can package. The device is ROHS3 compliant and carries MSL Level 1 rating, indicating unlimited moisture sensitivity protection.

Substitute parts are identified when electrical parameters, mechanical compatibility, and operational characteristics align within acceptable tolerances for the application circuit. Alternative sources and packaging configurations may be required due to inventory availability, supply chain considerations, or specific procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM236H-5.0 are qualified based on the following critical parameters:

• Fixed 5V output voltage matching the primary device
• 10 mA output current capability
• Shunt reference topology
• TO-46-3 metal can package compatibility
• Through-hole mounting configuration
• Operating temperature range of -25°C to 85°C
• Active product status with current manufacturing support

The LM236AH-5.0/NOPB variant shares identical electrical specifications with one exception: output tolerance of ±1% versus ±2%. This tighter tolerance represents an improvement in output accuracy and is electrically compatible for applications requiring the LM236H-5.0. The LM236H-5.0/NOPB variant differs only in packaging configuration (Bulk versus Tube), maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with current manufacturing support. The LM236H-5.0 and LM236H-5.0/NOPB are functionally identical, differing only in packaging configuration (Tube versus Bulk). Selection between these variants depends on procurement quantity and handling requirements.

The LM236AH-5.0/NOPB offers improved output tolerance specification (±1% versus ±2%), providing enhanced voltage accuracy. This part is electrically compatible and represents a direct upgrade path for applications requiring tighter output voltage regulation. Both Texas Instruments variants carry ROHS3 compliance and MSL Level 1 certification.

For applications requiring ROHS3 compliance and moisture sensitivity protection, the Texas Instruments LM236H-5.0 or LM236H-5.0/NOPB are specified selections. The National Semiconductor LM236AH-5.0/NOPB is suitable where compliance documentation is available through the supplier.

Frequently Asked Questions (FAQ)

Q: Can LM236AH-5.0/NOPB replace LM236H-5.0 in existing designs?

A: Yes. The LM236AH-5.0/NOPB is electrically compatible with identical output voltage (5V), output current (10 mA), cathode current (600 µA), operating temperature range (-25°C to 85°C), and package configuration (TO-46-3). The ±1% tolerance specification represents improved accuracy and is compatible with circuits designed for ±2% tolerance.

Q: What is the difference between LM236H-5.0 and LM236H-5.0/NOPB?

A: These parts are electrically and mechanically identical. The primary difference is packaging configuration: LM236H-5.0 is supplied in Tube packaging, while LM236H-5.0/NOPB is supplied in Bulk packaging. Selection depends on procurement quantity and handling requirements.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the TO-206AB, TO-46-3 metal can package with through-hole mounting configuration, ensuring direct mechanical compatibility on printed circuit boards.

Q: What compliance certifications apply to these parts?

A: The Texas Instruments variants (LM236H-5.0 and LM236H-5.0/NOPB) carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating. Compliance documentation for the National Semiconductor part should be verified through the supplier.

Q: Can these parts be used interchangeably in production?

A: Yes, within the specified electrical and mechanical parameters. All parts share identical reference type (Shunt), output type (Fixed), voltage output (5V), output current (10 mA), cathode current (600 µA), operating temperature range, and package configuration. Tolerance differences should be evaluated against circuit requirements.
