Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for NTC thermistors is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria are:

• Nominal resistance value at 25°C (4.7kΩ)
• Resistance tolerance (±5%)
• B-value specification (3977K) and tolerance (±0.75%)
• Maximum power dissipation (500 mW)
• Mounting type (Through Hole)
• Package configuration (Bead)

The NTCLE100E3472JB0 meets all core electrical specifications and mechanical requirements, establishing it as a direct functional equivalent despite differences in product status and operating temperature upper limit.

Parameter Comparison

Engineering Selection Recommendations

The NTCLE100E3472JB0 is the direct substitute for the obsolete NTCLE100CL472JB0. Both components share identical electrical characteristics across all critical parameters: 4.7kΩ nominal resistance, ±5% tolerance, 3977K B-value with ±0.75% tolerance, and 500 mW maximum power dissipation.

The primary distinction is the operating temperature upper limit: the substitute part is rated to 125°C versus the original part's 150°C. This difference is relevant only for applications requiring sustained operation above 125°C. For applications operating within the -40°C to 125°C range, the substitute provides full functional equivalence.

The NTCLE100E3472JB0 carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the NTCLE100E3472JB0 replace the NTCLE100CL472JB0 in all applications?

A: Yes, provided the application does not require sustained operation above 125°C. Both components are electrically identical across all specified parameters. Applications limited to the -40°C to 125°C range experience no functional difference.

Q: What is the significance of the operating temperature difference?

A: The original part is rated to 150°C; the substitute is rated to 125°C. This affects only applications requiring operation in the 125°C to 150°C range. Verify your application's maximum operating temperature requirement before selection.

Q: Are the bead packages mechanically identical?

A: Both components use identical Through Hole Bead packaging. No mechanical redesign or board layout modification is required for substitution.

Q: Does RoHS compliance affect substitution?

A: The substitute part is ROHS3 compliant, while the original is non-compliant. For new designs and regulated applications, the compliant substitute is preferred. Existing designs using the non-compliant original may continue operation without modification.

Q: Is the lead wire length specified for either part?

A: Lead wire length is not specified for the original part. The substitute specifies 0.59" (15.00mm) lead length. Verify this dimension against your application's mechanical requirements.
