LM336BDR-2-5 Equivalent & Substitute Parts

Part Overview

The LM336BDR-2-5 is a shunt voltage reference IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This fixed 2.49V reference device operates with ±2% tolerance and delivers 10 mA output current in an 8-SOIC surface mount package. The part is Active status and ROHS3 compliant. Substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable, when alternative tolerance specifications are acceptable, or when different distribution packaging (Tube, Cut Tape) is required for procurement or assembly workflows.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM336BDR-2-5 is determined by the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Reference Type: Shunt
• Output Type: Fixed
• Voltage - Output: 2.49V
• Current - Output: 10 mA
• Current - Cathode: 400 µA
• Operating Temperature Range: 0°C ~ 70°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Allowable Variation:

• Tolerance: The main part specifies ±2%. Substitute parts with ±4% tolerance are electrically compatible but represent a relaxed accuracy specification.
• Packaging Format: Substitutes differ in distribution packaging (Tube, Cut Tape & Digi-Reel®, Tape & Reel) but maintain identical component specifications and pin configuration.

All substitute parts share the same base product number (LM336), manufacturer (Texas Instruments), product status (Active), and compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Identical Electrical Specifications): LM336BMX-2.5/NOPB is the recommended substitute when Tape & Reel packaging is required. This part maintains ±2% tolerance matching the original LM336BDR-2-5 and offers the highest inventory availability (15,825 Pcs). Both parts are Active status and ROHS3 compliant.

Secondary Substitute (Relaxed Tolerance): LM336MX-2.5/NOPB provides the largest inventory stock (32,279 Pcs) and is suitable for applications where ±4% tolerance is acceptable. This part is distributed in Cut Tape & Digi-Reel® format and maintains all other electrical and mechanical specifications.

Tube Packaging Alternatives: LM336BM-2.5/NOPB (±2% tolerance) and LM336M-2.5/NOPB (±4% tolerance) are available in Tube packaging for manual assembly or lower-volume procurement workflows.

All substitute parts maintain identical pin configuration, operating temperature range, and compliance certifications (ROHS3, REACH Unaffected, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can LM336MX-2.5/NOPB replace LM336BDR-2-5 in my design? A: Yes, provided your circuit design tolerates ±4% voltage tolerance. The LM336MX-2.5/NOPB maintains identical output voltage (2.49V), current ratings (10 mA output, 400 µA cathode), operating temperature range (0°C ~ 70°C), and 8-SOIC package dimensions. The tolerance specification is the only electrical difference.

Q: What is the difference between Tape & Reel, Tube, and Cut Tape packaging? A: These are distribution packaging formats that do not affect component performance. Tape & Reel (TR) is used for automated assembly lines. Tube packaging is used for manual assembly or lower-volume orders. Cut Tape & Digi-Reel® combines both formats. The actual component specifications remain identical.

Q: Are all substitute parts from Texas Instruments? A: Yes, all substitute parts listed are manufactured by Texas Instruments and share the same base product number (LM336). All are Active status products.

Q: Do substitute parts have the same pin configuration? A: Yes, all substitute parts use the 8-SOIC package with identical pin configuration and mechanical dimensions (0.154", 3.90mm Width).

Q: Which substitute has the best availability? A: LM336MX-2.5/NOPB has the highest inventory (32,279 Pcs). If ±2% tolerance is required, LM336BMX-2.5/NOPB offers 15,825 Pcs in Tape & Reel format.

Q: Are all substitutes ROHS3 compliant? A: Yes, all substitute parts are ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level) and REACH Unaffected status.
