Substitute Part Grouping Explanation

Substitution eligibility for NTC thermistor NTCLE100CL154JB0 is determined by the following critical parameters:

• Resistance value at 25°C: 150kΩ (exact match required)
• B value (B25/85): 4370K (exact match required)
• Resistance tolerance: ±5% (must be equal or tighter)
• B value tolerance: ±2.5% (must be equal or tighter)
• Mounting type: Through Hole (mechanical compatibility)
• Package type: Bead (form factor requirement)
• Maximum power rating: 500mW (minimum requirement)
• Operating temperature range: Must encompass or match the application requirement

The substitute part NTCLE100E3154JB0 meets all electrical and mechanical compatibility criteria, with identical resistance, B value, tolerance specifications, and mounting configuration. The primary distinction lies in product status (active vs. obsolete) and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

NTCLE100E3154JB0 is the direct substitute for NTCLE100CL154JB0. Both components share identical electrical characteristics: 150kΩ resistance at 25°C, 4370K B value, and equivalent tolerance specifications. Both are rated for 500mW maximum power and feature through-hole bead packaging.

The substitute part offers two significant advantages: active product status ensures continued availability and supply chain reliability, and ROHS3 compliance aligns with current regulatory requirements. The operating temperature range of the substitute (-40°C to 125°C) is narrower than the original (-40°C to 150°C) by 25°C at the upper limit. This difference must be evaluated against the specific application's maximum operating temperature requirement.

Selection of NTCLE100E3154JB0 is appropriate for applications where the 125°C upper temperature limit is sufficient and where RoHS3 compliance is required or preferred.

Frequently Asked Questions (FAQ)

Q: What makes NTCLE100E3154JB0 a valid substitute for NTCLE100CL154JB0?

A: Both components are NTC thermistors with identical electrical specifications: 150kΩ resistance at 25°C, 4370K B value, ±5% resistance tolerance, and ±2.5% B value tolerance. Both are rated for 500mW maximum power and use through-hole bead packaging. These parameters determine functional equivalence in thermistor applications.

Q: What is the difference in operating temperature range?

A: NTCLE100CL154JB0 operates from -40°C to 150°C, while NTCLE100E3154JB0 operates from -40°C to 125°C. The substitute has a 25°C lower maximum temperature rating. Applications requiring operation above 125°C cannot use the substitute without thermal performance verification.

Q: Why is the original part obsolete?

A: NTCLE100CL154JB0 is classified as obsolete by the manufacturer. NTCLE100E3154JB0 is the active equivalent, ensuring long-term availability and supply chain continuity.

Q: Does RoHS3 compliance matter for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many other markets. NTCLE100E3154JB0 meets ROHS3 requirements, while NTCLE100CL154JB0 does not. Regulatory requirements for your end application determine whether this distinction is relevant.

Q: Are the lead wire specifications important?

A: NTCLE100E3154JB0 specifies lead wire length as 0.59" (15.00mm). The original part does not provide this specification. If lead wire length is critical for your assembly process or mechanical design, verify compatibility before substitution.

Q: Can I use these parts interchangeably in existing designs?

A: Electrical interchangeability is confirmed based on resistance, B value, tolerance, power rating, and mounting type. Mechanical interchangeability depends on lead wire length compatibility and the specific PCB layout or assembly requirements of your design.
