Substitute Part Grouping Explanation

Substitution eligibility for the LM336M-2.5 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt voltage reference architecture
• Output Voltage: Fixed 2.49V output
• Output Current: 10 mA capability
• Voltage Tolerance: ±4% accuracy specification
• Cathode Current: 400 µA specification
• Package Configuration: 8-SOIC surface mount form factor
• Operating Temperature Range: 0°C to 70°C
• Compliance Standards: ROHS3, REACH Unaffected

Only components matching all these parameters across electrical and mechanical specifications qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The LM336M-2.5/NOPB is the direct substitute for LM336M-2.5. Both components are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product status: LM336M-2.5 is designated Last Time Buy, while LM336M-2.5/NOPB maintains Active status. For new designs and ongoing procurement, LM336M-2.5/NOPB is the recommended selection due to its active product lifecycle status and continued availability. Both parts satisfy ROHS3 compliance and REACH requirements, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: What is the difference between LM336M-2.5 and LM336M-2.5/NOPB?

A: Both parts are electrically and mechanically identical. The "/NOPB" designation indicates "No Lead (Pb)" plating, confirming RoHS compliance. The primary difference is product lifecycle status: LM336M-2.5 is Last Time Buy, while LM336M-2.5/NOPB is Active.

Q: Can LM336M-2.5/NOPB be used as a direct replacement in existing designs?

A: Yes. LM336M-2.5/NOPB is a direct substitute with identical voltage output (2.49V), tolerance (±4%), current specifications (10 mA output, 400 µA cathode), package configuration (8-SOIC), and operating temperature range (0°C to 70°C).

Q: Are there any compliance or certification differences?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What should be considered when transitioning from LM336M-2.5 to LM336M-2.5/NOPB?

A: No design changes are required. The parts are pin-compatible, functionally equivalent, and maintain identical performance characteristics. Transition is a direct substitution at the component level.

Q: Is the 8-SOIC package standard across both parts?

A: Yes. Both LM336M-2.5 and LM336M-2.5/NOPB use the 8-SOIC package with 0.154" (3.90mm) width, ensuring PCB layout compatibility.
