Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERT-D2FGL601S is determined by the following critical parameters:

• Resistance Value @ 25°C: Must be 600Ω to maintain circuit calibration and sensor response characteristics
• Mounting Configuration: Must support through-hole mounting to ensure mechanical compatibility with existing PCB layouts
• Package Form Factor: Disc configuration required for thermal coupling and physical fit
• Operating Temperature Range: Must encompass or exceed the -30°C to 60°C specification to ensure functional operation across all intended conditions
• Power Dissipation Rating: Must meet or exceed 400mW to prevent thermal stress and premature failure
• Resistance Tolerance: Acceptable variance from nominal 600Ω value; tighter tolerances provide improved accuracy

The MF11-0060005 from Cantherm meets all primary substitution criteria, maintaining the 600Ω resistance specification and through-hole disc configuration while offering enhanced operating temperature range and power handling capability.

Parameter Comparison

Engineering Selection Recommendations

The MF11-0060005 serves as a direct functional substitute for the obsolete ERT-D2FGL601S based on the following engineering criteria:

Electrical Compatibility: Both components maintain 600Ω resistance at 25°C, the primary electrical specification for circuit operation. The MF11-0060005 provides superior resistance tolerance (±5% versus ±15%), reducing measurement uncertainty in temperature sensing applications.

Thermal Performance: The MF11-0060005 operates across -55°C to 125°C, fully encompassing the original -30°C to 60°C requirement. The B25/50 value difference (3600K versus 4000K) represents a 10% variation in temperature sensitivity; this variance must be evaluated against specific application requirements and calibration procedures.

Power Handling: The substitute component supports 500mW dissipation, exceeding the 400mW specification of the original part, providing additional thermal margin in power-limited applications.

Mechanical Fit: Both components employ through-hole disc configurations. The MF11-0060005 features a 6.5mm diameter versus the 5mm specification; physical clearance verification is required for confined PCB layouts.

Supply Status: The MF11-0060005 is actively manufactured and maintains current inventory levels, ensuring long-term availability for production and field replacement applications.

Compliance: The MF11-0060005 carries RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the MF11-0060005 be used as a direct drop-in replacement for the ERT-D2FGL601S?

A: The MF11-0060005 is electrically and functionally compatible as a substitute. Both components share 600Ω resistance at 25°C and through-hole disc mounting. Physical verification is required due to the larger 6.5mm diameter of the substitute versus the 5mm original specification. PCB layout clearance must be confirmed before implementation.

Q: What is the significance of the B25/50 value difference between the two parts?

A: The B25/50 value defines the thermistor's temperature sensitivity. The ERT-D2FGL601S specifies 4000K while the MF11-0060005 specifies 3600K, representing a 10% difference in the temperature coefficient. This affects the resistance-versus-temperature curve. Applications requiring precise temperature measurement across the full operating range should validate calibration curves and measurement accuracy with the substitute component.

Q: Does the larger package diameter of the MF11-0060005 affect thermal response?

A: The 6.5mm diameter of the MF11-0060005 versus the 5mm original may affect thermal coupling characteristics and response time. The larger mass can result in slower thermal response in dynamic temperature measurement scenarios. Thermal time constant validation is recommended for applications with rapid temperature transients.

Q: Is the MF11-0060005 suitable for new designs?

A: Yes. The MF11-0060005 is actively manufactured with current inventory availability. It meets modern compliance standards (RoHS3, REACH unaffected) and offers enhanced specifications including wider operating temperature range and superior power dissipation capability. New designs should incorporate the MF11-0060005 rather than seeking the obsolete ERT-D2FGL601S.

Q: What certifications and compliance standards apply to the substitute part?

A: The MF11-0060005 carries RoHS3 compliance and is REACH unaffected. Both components share the same ECCN (EAR99) and HTSUS classification (8533.40.8070), ensuring consistent regulatory treatment in procurement and export scenarios.
