LM336BLPR-2-5 Equivalent & Substitute Parts

Part Overview

The LM336BLPR-2-5 is a shunt voltage reference IC manufactured by Texas Instruments, designed for precision voltage regulation applications. This fixed 2.49V reference device operates with ±2% tolerance and supports 10 mA output current in a TO-92-3 through-hole package. The part is currently in active production status with 1650 units available in new original inventory. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, design flexibility, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM336BLPR-2-5 is determined by the following critical parameters:

• Fixed Output Voltage: 2.49V (must match exactly)
• Output Current Capability: 10 mA (must match or exceed)
• Cathode Current: 400 µA (must match)
• Package Type: TO-92-3 through-hole (must match for PCB compatibility)
• Reference Type: Shunt (functional classification)
• Operating Temperature Range: 0°C ~ 70°C (must match or exceed)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The LM336Z-2.5/LFT7 qualifies as a substitute part because it maintains identical electrical specifications for output voltage, output current, cathode current, operating temperature range, and package configuration. The tolerance specification differs (±4% versus ±2%), which represents a relaxation of the accuracy requirement and does not prevent substitution in applications where the tighter tolerance of the primary part is not mandatory.

Parameter Comparison

Engineering Selection Recommendations

Both the LM336BLPR-2-5 and LM336Z-2.5/LFT7 are active production parts manufactured by Texas Instruments with ROHS3 compliance and identical regulatory status (REACH Unaffected, ECCN EAR99). Selection between these parts should be based on tolerance requirements specific to the application circuit. The LM336BLPR-2-5 provides ±2% accuracy, suitable for applications requiring tighter voltage reference precision. The LM336Z-2.5/LFT7 provides ±4% accuracy and is appropriate for applications where this tolerance specification meets design requirements. Both parts are pin-compatible and functionally interchangeable within their respective tolerance specifications. Inventory availability may also influence part selection, with the LM336Z-2.5/LFT7 currently showing higher stock levels (4963 units versus 1650 units).

Frequently Asked Questions (FAQ)

Q: Can the LM336Z-2.5/LFT7 be used as a direct replacement for the LM336BLPR-2-5?

A: Yes, the LM336Z-2.5/LFT7 is electrically and mechanically compatible. Both parts provide identical 2.49V output, 10 mA current capability, and TO-92-3 package configuration. The tolerance difference (±4% versus ±2%) must be evaluated against circuit requirements.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. The LM336BLPR-2-5 guarantees ±2% output voltage accuracy, while the LM336Z-2.5/LFT7 guarantees ±4% accuracy. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for the same PCB layout?

A: Yes. Both parts use the TO-92-3 through-hole package with identical pin configuration and spacing, requiring no PCB modifications for substitution.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99, meeting current regulatory standards.

Q: Which part should be selected for a precision analog circuit?

A: Application requirements determine the appropriate selection. If the circuit design specifies ±2% tolerance, use the LM336BLPR-2-5. If ±4% tolerance is acceptable, either part is suitable.

Q: Is there a temperature performance difference between these parts?

A: No. Both parts operate across the identical temperature range of 0°C to 70°C (TA).
