Substitute Part Grouping Explanation

Substitution of the LM4040C20ILPE3 is determined by strict equivalence across the following critical parameters:

• Reference voltage output: 2.048V fixed
• Output current capability: 15 mA
• Voltage tolerance: ±0.5%
• Temperature coefficient: 100ppm/°C
• Noise specification: 35µVrms (10Hz to 10kHz)
• Cathode current: 80 µA
• Operating temperature range: -40°C ~ 85°C
• Package type: TO-92-3 through-hole configuration
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

The LM4040C20ILP meets all parametric requirements for direct substitution. The primary distinction is packaging format (tape and reel versus tube) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The LM4040C20ILP is the direct parametric equivalent for the obsolete LM4040C20ILPE3. Both components share identical electrical specifications, thermal characteristics, and compliance certifications. The LM4040C20ILP maintains active product status with Texas Instruments, ensuring continued availability and manufacturing support. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The packaging difference (tube versus bulk) does not affect functional performance or pin compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the LM4040C20ILP be used as a direct replacement for the LM4040C20ILPE3?

A: Yes. Both components are electrically and mechanically identical across all specified parameters. The LM4040C20ILP is the active-status equivalent suitable for new designs and legacy system support.

Q: What is the difference between LM4040C20ILPE3 and LM4040C20ILP?

A: The primary difference is product status and packaging format. The LM4040C20ILPE3 is obsolete and supplied in tube packaging (PE3 suffix). The LM4040C20ILP is active and supplied in bulk packaging. Electrical performance and pin configuration are identical.

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

A: No compatibility concerns exist. Both parts use the TO-92-3 through-hole package with identical pinout and electrical characteristics. Direct board-level substitution is possible without circuit modification.

Q: What certifications apply to both parts?

A: Both the LM4040C20ILPE3 and LM4040C20ILP are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification.

Q: Is the LM4040C20ILP available in the same package?

A: Yes. Both parts use the TO-226-3 / TO-92-3 (TO-226AA) through-hole package configuration. Mounting type and pin spacing are identical.
