Key Parameters

Substitute Part Grouping Explanation

Substitution for the LM336MX-2.5 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output (Min/Fixed): 2.49V
• Current - Output: 10 mA
• Tolerance: ±4%
• Current - Cathode: 400 µA
• Operating Temperature Range: 0°C ~ 70°C (TA)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The substitute part LM336MX-2.5/NOPB maintains identical electrical specifications and mechanical packaging, differing only in product status (Active vs. Last Time Buy) and packaging format (Cut Tape & Digi-Reel® vs. standard packaging). This part is a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The LM336MX-2.5/NOPB is the direct substitute for LM336MX-2.5. Both parts are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications. The primary distinction is product status: LM336MX-2.5 is Last Time Buy, while LM336MX-2.5/NOPB is Active. Both parts comply with ROHS3 and REACH requirements, with MSL rating of 1 (Unlimited). Selection between these parts should be based on supply chain availability and procurement requirements, as the /NOPB variant offers continued active production status and availability through standard packaging formats (Cut Tape & Digi-Reel®).

Frequently Asked Questions (FAQ)

Q: Can LM336MX-2.5/NOPB replace LM336MX-2.5 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The /NOPB variant is the active production equivalent and provides direct substitution without design modification.

Q: What does the /NOPB suffix indicate?

A: The /NOPB suffix indicates "No Plumbum" (lead-free) packaging format supplied in Cut Tape and Digi-Reel® configurations. The base electrical specifications remain unchanged.

Q: Are there any package compatibility concerns?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin configurations and mounting requirements for surface mount assembly.

Q: What is the significance of Last Time Buy status?

A: Last Time Buy indicates the LM336MX-2.5 is discontinued. The LM336MX-2.5/NOPB is the recommended active production alternative for new designs and ongoing supply requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL rating of 1 (Unlimited), ensuring equivalent compliance for regulated applications.
