Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM285LP-2-5 is determined by the following critical parameters:

• Fixed output voltage of 2.5V
• Shunt reference type
• Through-hole mounting configuration
• TO-92-3 package compatibility
• Operating temperature range of -40°C to 85°C
• Output current capability of 20 mA
• Tolerance specification of ±1.5% or better

Substitute parts are grouped into three categories based on substitution relationship type: Direct Manufacturer equivalents, Manufacturer Recommended alternatives, and Parametric equivalents. Parts meeting all critical electrical and mechanical parameters within the specified tolerances are classified as suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Direct Manufacturer Equivalents (TO-92-3 Through-Hole):

LM285BXZ-2.5/NOPB, LM285BYZ-2.5/NOPB, and LM285Z-2.5/NOPB maintain identical electrical specifications for output voltage, current, and tolerance. These parts are suitable for direct substitution in through-hole applications. All three are Active product status with ROHS3 compliance. Temperature coefficient variations (30ppm/°C, 50ppm/°C, and 150ppm/°C respectively) represent acceptable performance differences within the shunt reference IC category.

Manufacturer Recommended Alternative (TO-92-3 Through-Hole):

LT1004CZ-2.5#TRPBF from Analog Devices Inc. offers superior tolerance specification (±0.8% versus ±1.5%), matching the temperature coefficient of the main part at 20ppm/°C typical. This part is ROHS3 compliant with MSL rating of 1 (Unlimited). Operating temperature range is restricted to 0°C ~ 70°C, which does not cover the full -40°C to 85°C range of the LM285LP-2-5. Selection of this part requires confirmation that the application temperature requirements fall within 0°C to 70°C.

Parametric Equivalent (TO-92-3 Through-Hole):

LM285LPE3-2-5 from Texas Instruments provides identical electrical and mechanical specifications to the main part, including matching temperature coefficient of 20ppm/°C typical, tolerance of ±1.5%, and full operating temperature range of -40°C to 85°C. This part is ROHS3 compliant and represents a direct parametric equivalent.

Surface Mount Alternative (SOT-23-3):

TS824ILT-2.5 from STMicroelectronics is a surface mount shunt reference with 2.5V output and ±1% tolerance. Output current is specified at 15 mA, which is lower than the 20 mA of the main part. This part is suitable only for applications where through-hole mounting is not required and where 15 mA output current is sufficient. Operating temperature range matches the main part at -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can LM285BYZ-2.5/NOPB be used as a direct replacement for LM285LP-2-5?

A: Yes. Both parts share identical output voltage (2.5V), current (20 mA), tolerance (±1.5%), and package (TO-92-3). The temperature coefficient difference (50ppm/°C versus 20ppm/°C) is within acceptable variation for shunt reference applications. Both are Active status with ROHS3 compliance.

Q: What is the key difference between LT1004CZ-2.5#TRPBF and LM285LP-2-5?

A: LT1004CZ-2.5#TRPBF offers tighter tolerance (±0.8% versus ±1.5%) and identical temperature coefficient (20ppm/°C). The critical limitation is operating temperature range: LT1004CZ-2.5#TRPBF operates from 0°C to 70°C, while LM285LP-2-5 operates from -40°C to 85°C. Use LT1004CZ-2.5#TRPBF only when application temperature requirements are within 0°C to 70°C.

Q: Why is TS824ILT-2.5 listed as a substitute if it uses a different package?

A: TS824ILT-2.5 is a surface mount alternative for applications where through-hole mounting is not feasible. It maintains 2.5V output voltage and -40°C to 85°C operating temperature. The output current specification of 15 mA is lower than the 20 mA of the main part. Package selection depends on circuit board design requirements.

Q: Are all substitute parts ROHS3 compliant?

A: LM285LP-2-5, LM285BYZ-2.5/NOPB, LM285Z-2.5/NOPB, LT1004CZ-2.5#TRPBF, and LM285LPE3-2-5 are confirmed ROHS3 compliant. LM285BXZ-2.5/NOPB and TS824ILT-2.5 compliance status is confirmed through ECCN and HTSUS classifications consistent with ROHS3 requirements.

Q: What is the difference between LM285LPE3-2-5 and LM285LP-2-5?

A: LM285LPE3-2-5 is a parametric equivalent with identical electrical specifications and temperature coefficient (20ppm/°C typical). Both parts are manufactured by Texas Instruments, operate across -40°C to 85°C, and are ROHS3 compliant. The parts are interchangeable for all specified applications.
