Substitute Part Grouping Explanation

Substitution for the LM4132EMF-4.1 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 4.096V
• Output tolerance of ±0.5%
• Output current capability of 20 mA
• Temperature coefficient of 30ppm/°C
• Input voltage range of 4.496V ~ 5.5V
• Supply current of 100µA
• Operating temperature range of -40°C ~ 125°C
• SOT-23-5 package configuration
• Surface mount mounting type

All identified substitute parts maintain identical electrical specifications and package requirements, ensuring direct functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The LM4132EMF-4.1 is obsolete and no longer in active production. Both substitute parts—LM4132EMF-4.1/NOPB and LM4132EMFX-4.1/NOPB—are active products with identical electrical and mechanical specifications.

LM4132EMF-4.1/NOPB is the primary substitute, manufactured by Texas Instruments with ROHS3 compliance and REACH unaffected status. This part is available in Tape & Reel packaging and represents the direct active equivalent.

LM4132EMFX-4.1/NOPB, manufactured by National Semiconductor, is also an active equivalent with identical electrical parameters. This part is available in bulk packaging and provides an alternative sourcing option.

Selection between these substitutes should be based on packaging requirements, compliance certifications applicable to the end application, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can LM4132EMF-4.1/NOPB be used as a direct replacement for the obsolete LM4132EMF-4.1?

A: Yes. Both parts share identical electrical specifications, including 4.096V fixed output, ±0.5% tolerance, 20 mA output current, and SOT-23-5 package configuration. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What is the difference between LM4132EMF-4.1/NOPB and LM4132EMFX-4.1/NOPB?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The differences are manufacturer (Texas Instruments vs. National Semiconductor) and packaging type (Tape & Reel vs. Bulk). Electrical performance is equivalent.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the SOT-23-5 package (SC-74A, SOT-753) with surface mount mounting type. PCB footprints and assembly processes remain unchanged.

Q: Does the packaging type (Tape & Reel vs. Bulk) affect electrical performance?

A: No. Packaging type affects procurement and handling logistics only. Electrical specifications and performance are identical regardless of packaging format.

Q: What compliance certifications should I verify for my application?

A: Verify RoHS and REACH compliance requirements for your specific end application. LM4132EMF-4.1/NOPB is ROHS3 compliant and REACH unaffected. Confirm compliance status for LM4132EMFX-4.1/NOPB with your supplier based on application requirements.
