LM336MX-5.0 Equivalent & Substitute Parts

Part Overview

The LM336MX-5.0 is a shunt voltage reference IC that provides a fixed 5V output with ±2% tolerance in an 8-SOIC surface mount package. This component is classified as obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. Shunt voltage references are critical in precision analog circuits for voltage regulation, biasing, and reference applications where stable output voltage is required across operating conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM336MX-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)
• Mounting Type: Surface Mount

The LM336MX-5.0/NOPB is a direct functional equivalent manufactured by Texas Instruments. Both parts share identical electrical specifications and physical packaging. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The LM336MX-5.0/NOPB is the direct substitute for the obsolete LM336MX-5.0. Both parts are electrically and mechanically identical across all specified parameters. The LM336MX-5.0/NOPB maintains active product status with Texas Instruments and carries ROHS3 compliance certification, whereas the original part is classified as obsolete and RoHS non-compliant. For new designs and ongoing production requiring this shunt voltage reference, the LM336MX-5.0/NOPB is the appropriate selection. Both parts are available in Cut Tape (CT) and Digi-Reel® packaging formats.

Frequently Asked Questions (FAQ)

Q: Can the LM336MX-5.0/NOPB be used as a direct replacement for the LM336MX-5.0?

A: Yes. Both parts are functionally equivalent with identical electrical specifications (5V fixed output, ±2% tolerance, 10 mA output current, 600 µA cathode current) and physical packaging (8-SOIC). Pin-for-pin compatibility is maintained.

Q: What does the "/NOPB" suffix indicate?

A: The "/NOPB" designation indicates the part is supplied without plumbum (lead-free), reflecting RoHS3 compliance. This is a packaging and compliance designation that does not affect electrical performance.

Q: Are there any temperature or operating condition differences between these parts?

A: No. Both parts operate across the identical temperature range of 0°C to 70°C (TA) with the same electrical characteristics maintained throughout.

Q: What is the difference in RoHS compliance between these parts?

A: The LM336MX-5.0 is RoHS non-compliant, while the LM336MX-5.0/NOPB is ROHS3 compliant. For applications subject to RoHS regulations or customer requirements, the LM336MX-5.0/NOPB is the required selection.

Q: Are both parts available in the same packaging options?

A: The LM336MX-5.0/NOPB is available in Cut Tape (CT) and Digi-Reel® formats. Both parts use the same 8-SOIC surface mount package with 0.154" width (3.90mm).

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
