NTCS0402E3104FHT Equivalent & Substitute Parts

Part Overview

The NTCS0402E3104FHT is an NTC thermistor manufactured by Vishay Beyschlag/Draloric/BC Components, rated at 100kΩ resistance at 25°C with a B25/85 value of 3950K. This surface mount component in 0402 (1005 Metric) package is designed for temperature sensing applications requiring automotive-grade reliability. The part maintains Active product status with full RoHS3 compliance and AEC-Q200 automotive qualification. Substitute parts are identified to address inventory availability, extended operating temperature ranges, or alternative packaging formats while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTCS0402E3104FHT is determined by the following mandatory parameters:

• Resistance value at 25°C: 100kΩ (exact match required)
• Resistance tolerance: ±1% (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The identified substitute parts NTCG104EF104FT1X and NTCG104KF104FT1 satisfy all mandatory electrical and mechanical parameters. Variations in B value specifications and operating temperature ranges represent acceptable deviations within the NTC thermistor product category, as these parameters do not affect physical compatibility or core thermal sensing functionality in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain Active product status and full ROHS3 compliance, ensuring regulatory alignment with the original NTCS0402E3104FHT. The NTCG104EF104FT1X offers improved B value tolerance (±1% versus ±3%) and higher power dissipation capability (100 mW versus 70 mW), with availability of 245,100 units in stock. The NTCG104KF104FT1 provides equivalent B value tolerance to the main part (±3%) and identical power dissipation upgrade (100 mW), available in Tape & Reel packaging format with 2,400 units in stock.

Selection between substitutes depends on application-specific requirements for B value accuracy and operating temperature ceiling. Applications requiring operation above 125°C must retain the original NTCS0402E3104FHT. Applications operating within -40°C to 125°C range may utilize either substitute without functional degradation.

Frequently Asked Questions (FAQ)

Q: Can NTCG104EF104FT1X and NTCG104KF104FT1 be used interchangeably with NTCS0402E3104FHT?

A: Both parts are mechanically and electrically compatible as direct substitutes. They share identical 100kΩ resistance at 25°C, ±1% tolerance, 0402 package format, and surface mount configuration. Differences in B value specifications and operating temperature ranges do not affect physical board compatibility or standard thermal sensing applications.

Q: What is the significance of B value differences between the main part and substitutes?

A: B value determines the thermistor's temperature coefficient and thermal response curve. The main part specifies B25/85 at 3950K, while substitutes range from 4308K to 4485K. These variations affect temperature measurement accuracy in precision applications but do not impact component interchangeability for general temperature sensing functions.

Q: Are there packaging format differences between the substitute parts?

A: NTCG104EF104FT1X is available in Cut Tape (CT) & Digi-Reel® format, matching the original part's packaging. NTCG104KF104FT1 is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly processes. Both formats are compatible with standard surface mount assembly equipment.

Q: What is the operating temperature limitation for substitute parts?

A: Both TDK substitutes are rated for -40°C to 125°C operation, compared to the original part's -40°C to 150°C range. Applications requiring sustained operation above 125°C must use the original NTCS0402E3104FHT.

Q: Do substitute parts maintain automotive-grade qualification?

A: The provided data confirms ROHS3 compliance and MSL 1 rating for all parts. Automotive qualification status (AEC-Q200) is specified only for the original NTCS0402E3104FHT. Verification of automotive qualification for TDK substitutes should be obtained directly from the manufacturer for safety-critical automotive applications.
