MF52F104F4150 NTC Thermistor Equivalent & Substitute Parts

Part Overview

The MF52F104F4150 is an NTC thermistor manufactured by Cantherm, designed for temperature sensing applications requiring a 100kΩ resistance at 25°C. This component operates across a temperature range of -55°C to 125°C and is packaged as a through-hole bead thermistor. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when inventory constraints, lead time requirements, or application-specific operating temperature ranges necessitate alternative sourcing while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MF52F104F4150 are identified based on the following criteria:

Electrical Compatibility:

• Resistance value at 25°C must be 100kΩ
• Resistance tolerance must be ±1% or better
• B value tolerance must be ±1% or better

Thermal Compatibility:

• Operating temperature range must encompass or exceed -55°C to 125°C
• Maximum power dissipation must be 50 mW or greater

Mechanical Compatibility:

• Mounting type must be through-hole
• Package form must be bead configuration

Regulatory Compliance:

• RoHS3 compliance required
• REACH unaffected status required

The B25/50 parameter (4150K for the main part) serves as a reference thermal coefficient. Substitute parts with alternative B-value specifications at different temperature points (B25/85, B25/100) remain functionally equivalent when the core 100kΩ @ 25°C specification and tolerance requirements are maintained.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: MF52F104F4150

Select the MF52F104F4150 when:

• Standard temperature range of -55°C to 125°C is sufficient for the application
• Cantherm component availability and lead times are acceptable
• Inventory stock of 1015 units meets procurement requirements

Substitute Part: B57560G1104F000

The B57560G1104F000 from EPCOS - TDK Electronics is electrically and mechanically equivalent to the MF52F104F4150 for applications within the -55°C to 125°C range. This substitute provides:

• Identical 100kΩ resistance at 25°C with ±1% tolerance
• Identical ±1% B value tolerance
• Extended operating temperature capability to 200°C, enabling use in higher-temperature applications
• ROHS3 compliance and REACH unaffected status matching the primary part
• Through-hole bead package compatible with existing PCB designs
• Inventory availability of 1290 units

The B57560G1104F000 is suitable for direct substitution in applications where the primary part is unavailable or when extended temperature operation to 200°C is required.

Frequently Asked Questions (FAQ)

Q: Can the B57560G1104F000 be used as a direct replacement for the MF52F104F4150?

A: Yes. Both parts share identical electrical specifications (100kΩ @ 25°C, ±1% tolerance, ±1% B value tolerance), identical power ratings (50 mW maximum), and compatible through-hole bead packaging. Both maintain ROHS3 compliance and REACH unaffected status. The B57560G1104F000 operates to 200°C versus 125°C for the MF52F104F4150, making it suitable for applications within the standard temperature range and beyond.

Q: What is the difference between the B25/50 and B25/85 parameters?

A: These parameters represent the B-value (thermal coefficient) measured at different temperature points. B25/50 indicates the B-value between 25°C and 50°C; B25/85 indicates the B-value between 25°C and 85°C. Both characterize the thermistor's temperature response. The MF52F104F4150 specifies B25/50 at 4150K, while the B57560G1104F000 specifies B25/85 at 4072K and B25/100 at 4092K. These different measurement points do not affect substitution compatibility when the core 100kΩ @ 25°C specification and tolerance requirements are met.

Q: Are there physical size differences between the bead and bead glass packages?

A: Both parts use bead form factor suitable for through-hole mounting. The B57560G1104F000 specifies a glass bead construction with a lead wire length of 2.64" (67.00mm). The MF52F104F4150 lead wire length is not specified in the provided data. Verify lead wire length compatibility with your specific PCB design before substitution.

Q: Which part should I select for applications requiring operation above 125°C?

A: The B57560G1104F000 is the appropriate choice for applications requiring operation up to 200°C. The MF52F104F4150 is rated to 125°C maximum and is not suitable for higher-temperature applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the MF52F104F4150 and B57560G1104F000 are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards for component selection.
