LM4050AIM3-10 Equivalent & Substitute Parts

Part Overview

The LM4050AIM3-10 is a shunt voltage reference IC that generates a fixed 10V output with ±0.1% tolerance. This precision voltage reference is designed for applications requiring stable reference voltages in power management circuits. The main part is currently obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain identical electrical specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM4050AIM3-10 are qualified based on strict electrical and mechanical parameter matching. All substitute parts maintain identical specifications across the following critical parameters: reference type (shunt), output type (fixed), output voltage (10V), output current (15 mA), tolerance (±0.1%), temperature coefficient (50ppm/°C), noise characteristics (150µVrms at 10Hz to 10kHz), cathode current (103 µA), operating temperature range (-40°C ~ 85°C), and package type (SOT-23-3). These parameters define the functional equivalence required for direct substitution in circuit applications.

Engineering Selection Recommendations

For new designs and production applications, TL4050A10IDBZR and TL4050A10IDBZT are preferred substitutes due to active product status and ROHS3 compliance certification. Both parts are manufactured by Texas Instruments and maintain full electrical equivalence to the obsolete LM4050AIM3-10. The TL4050A10IDBZR variant is supplied in Tape & Reel packaging with higher inventory availability (22,629 pcs), making it suitable for high-volume production. The TL4050A10IDBZT variant is also Tape & Reel packaged with lower inventory (905 pcs). The LM4050AIM3-10/NOPB represents an alternative from National Semiconductor with active product status, though RoHS compliance information is not specified. All three substitute parts are electrically and mechanically interchangeable with the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can TL4050A10IDBZR directly replace LM4050AIM3-10 in existing circuits? A: Yes. Both parts are shunt voltage reference ICs with identical electrical specifications: 10V fixed output, ±0.1% tolerance, 50ppm/°C temperature coefficient, 15 mA output current, and SOT-23-3 package. Pin configuration and functional behavior are equivalent.

Q: What is the difference between TL4050A10IDBZR and TL4050A10IDBZT? A: Both parts are electrically identical. The difference lies in packaging format designation (R vs T suffix in Tape & Reel variants). Selection between them depends on supplier availability and procurement requirements.

Q: Why is the main part LM4050AIM3-10 marked as obsolete? A: The LM4050AIM3-10 has been discontinued by the manufacturer. Active substitute parts with equivalent specifications are available from Texas Instruments (TL4050A series) and National Semiconductor (LM4050AIM3-10/NOPB).

Q: Are the substitute parts RoHS compliant? A: TL4050A10IDBZR and TL4050A10IDBZT are ROHS3 compliant. The LM4050AIM3-10/NOPB RoHS status is not specified in available documentation.

Q: Can I use these parts interchangeably in production? A: Yes, all three substitute parts maintain identical electrical and mechanical parameters. PCB layout and circuit design require no modification. Verify supplier availability and lead times for your production schedule.

Q: What is the MSL rating for these parts? A: TL4050A10IDBZR and TL4050A10IDBZT have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling follow standard component guidelines.
