LM2936MM-5.0 Equivalent & Substitute Parts

Part Overview

The LM2936MM-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output at 50mA in an 8-VSSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The LM2936 series provides regulated 5V output with integrated protection features including over-temperature, reverse polarity, and short circuit protection, suitable for low-power applications requiring stable voltage regulation across the -40°C to 125°C operating temperature range.

Engineering Selection Recommendations

For applications requiring the LM2936MM-5.0, the following selection criteria apply based on product status and compliance requirements:

Primary Substitutes (Active Status, ROHS3 Compliant):

LM2936MM-5.0/NOPB: Direct replacement with Cut Tape and Digi-Reel packaging options. Recommended for standard industrial applications requiring RoHS3 compliance.
LM2936MMX-5.0/NOPB: Functionally equivalent with Tape & Reel packaging. Suitable for high-volume production environments.

Automotive-Grade Substitutes (AEC-Q100 Qualified):

LM2936QMM-5.0/NOPB: Automotive-qualified variant with Tape & Reel packaging. Required for automotive applications meeting AEC-Q100 standards.
LM2936QMMX-5.0/NOPB: Automotive-qualified variant with Tape & Reel packaging and highest inventory availability (4700 Pcs). Suitable for automotive production requiring AEC-Q100 qualification.

All substitute parts maintain identical electrical performance and mechanical compatibility with the obsolete LM2936MM-5.0. Selection between standard and automotive-grade variants depends on application requirements and end-use certification standards.

Frequently Asked Questions (FAQ)

Q: Can LM2936MM-5.0/NOPB directly replace the obsolete LM2936MM-5.0?

A: Yes. The LM2936MM-5.0/NOPB is electrically and mechanically identical to the obsolete LM2936MM-5.0, with the primary difference being active product status and ROHS3 compliance. Both share identical output voltage (5V), output current (50mA), dropout voltage (0.4V @ 50mA), and 8-VSSOP package configuration.

Q: What is the difference between LM2936MM-5.0/NOPB and LM2936MMX-5.0/NOPB?

A: Both parts are electrically identical with matching electrical specifications. The difference is packaging format: LM2936MM-5.0/NOPB is available in Cut Tape and Digi-Reel formats, while LM2936MMX-5.0/NOPB is supplied in Tape & Reel format. Selection depends on production volume and assembly line requirements.

Q: When should I use the automotive-grade variants (LM2936QMM-5.0/NOPB or LM2936QMMX-5.0/NOPB)?

A: Automotive-grade variants are required for applications subject to automotive industry standards and AEC-Q100 qualification requirements. These parts maintain identical electrical specifications but include automotive-grade qualification and testing. Use standard variants for non-automotive applications.

Q: Are all substitute parts RoHS compliant?

A: The original LM2936MM-5.0 is RoHS non-compliant. All substitute parts listed (LM2936MM-5.0/NOPB, LM2936MMX-5.0/NOPB, LM2936QMM-5.0/NOPB, LM2936QMMX-5.0/NOPB) are ROHS3 compliant, meeting current environmental regulations.

Q: Do all variants use the same 8-VSSOP package?

A: Yes. All parts in this substitution group use the 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) package configuration designated as 8-VSSOP. PCB layout and footprint compatibility is maintained across all variants.

Q: What inventory levels are available for each substitute?

A: LM2936MM-5.0/NOPB: 2404 Pcs; LM2936MMX-5.0/NOPB: 2961 Pcs; LM2936QMM-5.0/NOPB: 998 Pcs; LM2936QMMX-5.0/NOPB: 4700 Pcs. Inventory availability should be confirmed with your supplier for current stock status.
