Key Parameters

Substitute Part Grouping Explanation

Substitution of the LM336DR-2-5 is determined by the following critical parameters:

• Voltage Output: All substitute parts maintain the fixed 2.49V output specification
• Package Type: All substitute parts use the 8-SOIC form factor with identical 0.154" (3.90mm) width
• Mounting Type: All substitute parts are surface mount compatible
• Current Specifications: Output current (10 mA) and cathode current (400 µA) remain constant across all variants
• Operating Temperature Range: All parts operate within 0°C ~ 70°C (TA)
• Tolerance Variation: Substitute parts are available in both ±2% and ±4% tolerance grades
• Packaging Format: Substitute parts differ in delivery packaging (Tape & Reel, Tube, or Cut Tape & Digi-Reel)
• Compliance: All parts maintain ROHS3 compliance and MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

Selection among equivalent parts is based on the following criteria:

Tolerance Grade Selection: The LM336DR-2-5 operates at ±4% tolerance. Direct tolerance-matched substitutes include LM336M-2.5/NOPB and LM336MX-2.5/NOPB. Higher precision applications requiring ±2% tolerance can use LM336BM-2.5/NOPB or LM336BMX-2.5/NOPB, which provide tighter voltage regulation.

Packaging Format: For automated assembly processes requiring tape and reel format, LM336BMX-2.5/NOPB (±2% tolerance) or LM336MX-2.5/NOPB (±4% tolerance) are appropriate. For manual assembly or lower-volume applications, tube packaging options (LM336BM-2.5/NOPB or LM336M-2.5/NOPB) are available.

Inventory Availability: LM336MX-2.5/NOPB offers the highest stock level (32,279 units) with matching ±4% tolerance specification. LM336BMX-2.5/NOPB provides superior tolerance (±2%) with substantial inventory (15,825 units) in tape and reel format.

Compliance Status: All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active production status, ensuring long-term availability and regulatory conformance.

Frequently Asked Questions (FAQ)

Q: Can LM336BM-2.5/NOPB replace LM336DR-2-5 in my design? A: Yes. Both parts share identical voltage output (2.49V), current specifications (10 mA output, 400 µA cathode), operating temperature range (0°C ~ 70°C), and 8-SOIC package dimensions. LM336BM-2.5/NOPB provides superior tolerance (±2% versus ±4%), making it a direct functional substitute. The primary difference is packaging format (Tube versus Tape & Reel).

Q: What is the difference between LM336MX-2.5/NOPB and LM336BMX-2.5/NOPB? A: Both parts use Tape & Reel packaging and the 8-SOIC form factor. The primary distinction is tolerance specification: LM336MX-2.5/NOPB operates at ±4% tolerance (matching the original LM336DR-2-5), while LM336BMX-2.5/NOPB provides ±2% tolerance for applications requiring higher precision voltage regulation.

Q: Are all substitute parts compatible with the same PCB layout? A: Yes. All substitute parts use the identical 8-SOIC package with 0.154" (3.90mm) width and surface mount configuration. PCB footprints and assembly processes remain unchanged across all listed variants.

Q: Which substitute part offers the best inventory availability? A: LM336MX-2.5/NOPB provides the highest stock level at 32,279 units while maintaining the original ±4% tolerance specification and 8-SOIC package format.

Q: Do all substitute parts meet the same compliance requirements? A: Yes. All listed parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain active production status with identical REACH and ECCN classifications.
