LM4040C30ILPE3 Equivalent & Substitute Parts

Part Overview

The LM4040C30ILPE3 is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage reference applications requiring fixed 3V output. This active product operates as a shunt regulator with ±0.5% tolerance and 15 mA output capability. The device is packaged in TO-92-3 (TO-226AA) through-hole configuration and is ROHS3 compliant. Substitute parts are identified when electrical parameters, mechanical compatibility, and regulatory compliance align with the original specification.

Substitute Part Grouping Explanation

Substitution of the LM4040C30ILPE3 is determined by strict equivalence across the following critical parameters:

• Reference Type: Shunt
• Output Voltage: 3V (fixed)
• Output Current: 15 mA
• Tolerance: ±0.5%
• Temperature Coefficient: 100ppm/°C
• Noise Performance: 35µVrms (10Hz to 10kHz)
• Cathode Current: 82 µA
• Operating Temperature Range: -40°C ~ 85°C
• Package: TO-92-3 through-hole configuration
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The LM4040C30ILP variant meets all electrical and mechanical requirements for direct substitution. Packaging differences (tape and reel vs. bulk) do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the LM4040C30ILPE3 and LM4040C30ILP are active products from Texas Instruments with identical electrical specifications and regulatory compliance. Selection between these variants is based on packaging and supply chain requirements:

• LM4040C30ILPE3: Tape and reel packaging (ILPE3 suffix), suitable for automated assembly processes
• LM4040C30ILP: Bulk packaging, suitable for manual assembly or lower-volume applications

Both variants maintain ROHS3 compliance and REACH unaffected status. No functional or performance differences exist between the two parts.

Frequently Asked Questions (FAQ)

Q: Can LM4040C30ILP be used as a direct replacement for LM4040C30ILPE3?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only (tape and reel vs. bulk). Functional performance, electrical characteristics, and pin configuration are equivalent.

Q: Are there any differences in tolerance or temperature coefficient between these variants?

A: No. Both parts maintain ±0.5% tolerance and 100ppm/°C temperature coefficient across the full operating range of -40°C to 85°C.

Q: What is the significance of the ILPE3 and ILP suffixes?

A: The suffix indicates packaging format. ILPE3 denotes tape and reel packaging suitable for pick-and-place assembly. ILP denotes bulk packaging. Electrical specifications remain identical.

Q: Are both parts ROHS3 compliant?

A: Yes. Both LM4040C30ILPE3 and LM4040C30ILP are ROHS3 compliant and REACH unaffected.

Q: What is the TO-92-3 package configuration?

A: TO-92-3 is a three-lead through-hole package (also designated TO-226AA). Pin configuration and mechanical dimensions are identical between both variants.

Q: Can these parts be used interchangeably in production?

A: Yes, provided your assembly process can accommodate the packaging format. Automated assembly typically uses tape and reel (ILPE3), while manual or low-volume assembly may use bulk packaging (ILP).
