Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NB20N00823KBA are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: 1206 (3216 Metric) surface mount form factor
• Mounting Type: Surface Mount
• Category: Temperature Sensors (NTC Thermistor)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Electrical Parameters:

• Resistance Tolerance: ±5% to ±10%
• B Value Tolerance: ±3%
• Operating Temperature Range: Must encompass or align with application requirements

The identified substitute parts maintain identical package specifications and compliance certifications. Resistance values and B-value characteristics differ from the main part, reflecting alternative thermal response profiles suitable for different temperature sensing applications within the same physical and environmental constraints.

Parameter Comparison

Engineering Selection Recommendations

NB20N00823KBA (Main Part - Recommended for New Designs)

The NB20N00823KBA maintains Active product status and is the preferred selection for new design implementations. This part offers the highest resistance value (82kΩ) among the available options with a B25/85 value of 4080K, providing specific thermal response characteristics for temperature sensing applications requiring higher impedance levels.

NTHS1206N01N5002JE (Vishay Dale - 50kΩ)

This substitute provides a mid-range resistance value of 50kΩ with a B25/75 value of 3964K. The part carries a "Not For New Designs" status, indicating it is suitable for legacy system support or replacement applications only. Tighter resistance tolerance (±5%) compared to the main part may provide improved consistency in specific applications.

NTHS1206N11N2202JE (Vishay Dale - 22kΩ)

This substitute offers the lowest resistance value at 22kΩ with a B25/75 value of 3700K. Like the 50kΩ variant, this part is designated "Not For New Designs" and is appropriate for legacy applications or direct replacement scenarios. The lower resistance value suits applications requiring lower impedance thermal sensing.

All substitute parts maintain identical physical packaging, RoHS3 compliance, and MSL ratings, ensuring mechanical and environmental compatibility with the main part.

Frequently Asked Questions (FAQ)

Q: Can NTHS1206N01N5002JE or NTHS1206N11N2202JE be used as direct replacements for NB20N00823KBA?

A: These parts share identical package specifications (1206 / 3216 Metric), mounting type (Surface Mount), and compliance certifications (ROHS3, MSL 1). However, they have different resistance values (50kΩ and 22kΩ respectively versus 82kΩ) and different B-value characteristics. Substitution is valid only if the application circuit design accommodates these electrical parameter differences.

Q: What is the significance of the "Not For New Designs" status on the Vishay Dale substitutes?

A: This designation indicates these parts are in mature or end-of-life phases and are maintained primarily for legacy system support and replacement applications. For new product development, the NB20N00823KBA (Active status) is the appropriate selection.

Q: Are all three parts physically interchangeable on a PCB?

A: Yes. All three parts use the 1206 (3216 Metric) surface mount package with identical footprint dimensions, allowing direct PCB placement without layout modifications. However, electrical circuit behavior will differ due to resistance and B-value variations.

Q: What compliance certifications are maintained across all parts?

A: All parts are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental and regulatory compliance for applications requiring these certifications.

Q: How do the B-value differences affect thermistor performance?

A: B-value determines the thermistor's thermal response curve. The main part (NB20N00823KBA) specifies B25/85 at 4080K, while substitutes provide B25/75 values (3964K and 3700K). These differences result in different temperature-to-resistance relationships. Selection must align with the specific temperature sensing range and accuracy requirements of the application.
