Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM4132AMF-4.1 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 4.096V
• Output current capability of 20 mA
• Tolerance specification of ±0.05%
• Temperature coefficient of 20ppm/°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

Two active equivalent part numbers from Texas Instruments meet these criteria. Substitution is valid only when all electrical and mechanical parameters align with the specifications above.

Engineering Selection Recommendations

For new designs and ongoing production, LM4132AMF-4.1/NOPB and LM4132AMFX-4.1/NOPB are the recommended alternatives to the obsolete LM4132AMF-4.1. Both substitute parts carry Active product status and ROHS3 compliance, meeting current regulatory requirements.

LM4132AMF-4.1/NOPB is supplied in Cut Tape (CT) & Digi-Reel® packaging format, suitable for lower-volume applications and manual assembly processes. LM4132AMFX-4.1/NOPB is supplied in Tape & Reel (TR) format, optimized for high-volume automated manufacturing environments.

All three part numbers are electrically and mechanically identical across all specified parameters. Selection between the two active alternatives depends solely on packaging and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can LM4132AMF-4.1/NOPB directly replace LM4132AMF-4.1?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The primary difference is product status (Active vs. Not For New Designs) and RoHS compliance (ROHS3 Compliant vs. non-compliant). The /NOPB suffix indicates lead-free termination.

Q: What is the difference between LM4132AMF-4.1/NOPB and LM4132AMFX-4.1/NOPB?

A: Both parts are parametrically equivalent with identical electrical specifications. The difference lies in packaging format: LM4132AMF-4.1/NOPB uses Cut Tape (CT) & Digi-Reel® packaging, while LM4132AMFX-4.1/NOPB uses Tape & Reel (TR) packaging. Selection depends on manufacturing volume and assembly equipment compatibility.

Q: Are these parts pin-compatible?

A: Yes. All three part numbers use the SOT-23-5 package (SC-74A, SOT-753), ensuring identical pinout and PCB footprint compatibility.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB suffix indicates lead-free (Pb-free) termination and RoHS3 compliance, meeting current environmental and regulatory standards.

Q: Can I use these parts interchangeably in my existing designs?

A: Yes, provided your PCB design accommodates the SOT-23-5 package and your supply chain can support the selected packaging format. All electrical parameters remain constant across the three part numbers.
