Parameter Comparison

Engineering Selection Recommendations

For applications requiring the LM4132CMFX-4.1, the following selection criteria apply:

LM4132CMFX-4.1/NOPB (National Semiconductor): This direct manufacturer equivalent maintains all electrical and mechanical specifications. Product status is active, ensuring continued availability. Selection is appropriate when National Semiconductor sourcing is preferred or when bulk packaging is acceptable.

LM4132CMF-4.1/NOPB (Texas Instruments): This parametric equivalent from Texas Instruments is the preferred substitute for new designs and ongoing procurement. The part is active and ROHS3 compliant, meeting modern regulatory requirements. Cut Tape and Digi-Reel packaging options provide flexibility for production volumes. This part is recommended as the primary replacement for the obsolete LM4132CMFX-4.1.

Both substitutes are electrically and mechanically interchangeable with the original part number across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can LM4132CMF-4.1/NOPB directly replace LM4132CMFX-4.1 in existing designs?

A: Yes. Both parts share identical electrical specifications including 4.096V fixed output, ±0.2% tolerance, 20 mA output current, and SOT-23-5 packaging. Direct substitution is supported without circuit modification.

Q: What is the difference between LM4132CMFX-4.1/NOPB and LM4132CMF-4.1/NOPB?

A: Both are parametric equivalents with identical electrical performance. The primary differences are manufacturer (National Semiconductor vs. Texas Instruments), product status (both active), and packaging options. LM4132CMF-4.1/NOPB offers ROHS3 compliance, making it suitable for applications with regulatory requirements.

Q: Are there packaging differences between the substitute parts?

A: All three parts use SOT-23-5 surface mount packaging (SC-74A, SOT-753). Packaging format differences exist at the supplier level: LM4132CMFX-4.1/NOPB is supplied in bulk, while LM4132CMF-4.1/NOPB is available in Cut Tape and Digi-Reel formats. These differences do not affect electrical or mechanical compatibility.

Q: Is the LM4132CMFX-4.1 still available for procurement?

A: The LM4132CMFX-4.1 is classified as obsolete. Active substitutes LM4132CMFX-4.1/NOPB and LM4132CMF-4.1/NOPB are recommended for new procurement and design continuity.

Q: Do the substitute parts meet the same compliance standards?

A: All parts share REACH Unaffected and EAR99 ECCN classifications. LM4132CMF-4.1/NOPB is ROHS3 compliant, while the original part is RoHS non-compliant. For applications requiring RoHS compliance, LM4132CMF-4.1/NOPB is the appropriate selection.
