LM336M-5.0 Equivalent & Substitute Parts

Part Overview

The LM336M-5.0 is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage regulation applications requiring a fixed 5V output. This component operates as a shunt regulator with ±2% tolerance and 10 mA output capability in an 8-SOIC surface mount package.

The LM336M-5.0 carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status necessitates identifying equivalent substitute parts to ensure design continuity and supply chain reliability for new production runs and ongoing support of existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM336M-5.0 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 5V
• Current - Output: 10 mA
• Tolerance: ±2%
• Current - Cathode: 600 µA
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)

All substitute parts must match these specifications exactly. Deviations in any parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

LM336M-5.0/NOPB is the primary substitute for LM336M-5.0. This part maintains identical electrical and mechanical specifications while carrying Active product status from Texas Instruments. The /NOPB designation indicates lead-free plating compliance. ROHS3 compliance is maintained, ensuring regulatory alignment with current environmental standards.

LM336MX-5.0 matches all electrical and mechanical parameters but carries Obsolete product status and RoHS non-compliant certification. This part should be avoided for new designs and long-term production applications due to its discontinued status and non-compliance with current environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can LM336M-5.0/NOPB be used as a direct replacement for LM336M-5.0?

A: Yes. Both parts are electrically and mechanically identical, with matching voltage output (5V), current ratings (10 mA output, 600 µA cathode), tolerance (±2%), operating temperature range (0°C ~ 70°C), and 8-SOIC package specifications. The primary difference is product status; LM336M-5.0/NOPB is Active while LM336M-5.0 is Last Time Buy.

Q: Why is LM336MX-5.0 listed as a substitute if it is Obsolete?

A: LM336MX-5.0 meets all electrical and mechanical substitution criteria. However, its Obsolete status and RoHS non-compliance make it unsuitable for new designs or ongoing production. It is included for reference only in legacy system documentation.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pinout and mechanical dimensions, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the /NOPB designation?

A: The /NOPB suffix indicates lead-free plating, confirming compliance with RoHS directives and modern manufacturing standards. This designation does not affect electrical performance or functional compatibility.
