Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERT-D2FGL750S is determined by the following critical parameters:

• Resistance value at 25°C must be 75 ohms
• Mounting type must be through hole
• Package form factor must be disc configuration
• Operating temperature range must encompass or exceed the original specification
• Power dissipation capability must meet or exceed 400 mW
• B value characteristics must be compatible with the thermal response requirements

The identified substitute parts (MF11-0007505 and MF11-0007510) meet these core electrical and mechanical criteria, though with variations in tolerance specifications and extended operating temperature ranges.

Parameter Comparison

Engineering Selection Recommendations

Both Cantherm MF11-0007505 and MF11-0007510 thermistors provide functional equivalence to the obsolete Panasonic ERT-D2FGL750S based on core electrical parameters. Key considerations for selection:

MF11-0007505 offers tighter resistance tolerance (±5%) compared to the original part (±15%), providing improved accuracy in temperature sensing circuits. This part carries ROHS3 compliance and REACH unaffected status.

MF11-0007510 provides intermediate resistance tolerance (±10%) with identical compliance certifications. Both substitute parts feature extended operating temperature ranges (-55°C ~ 125°C) and increased power dissipation capability (500 mW), offering enhanced performance margins beyond the original specification.

The B value difference (3000K versus 3700K) represents a variation in thermal response characteristics that must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can MF11-0007505 and MF11-0007510 be used interchangeably with ERT-D2FGL750S?

A: Both parts share the same 75 ohm resistance value and through-hole disc mounting configuration. Selection between them depends on tolerance requirements and thermal response characteristics specific to your application.

Q: What is the significance of the B value difference (3700K vs 3000K)?

A: The B value determines the thermistor's thermal response curve. The 700K difference between the original part and substitutes will produce different resistance changes across the operating temperature range. Application-specific thermal modeling is required to confirm compatibility.

Q: Are the substitute parts physically compatible with the original PCB layout?

A: Both substitute parts use through-hole mounting with disc form factors. The Cantherm parts have a slightly larger diameter (6.5mm vs 5mm), which may require PCB layout verification for clearance and spacing.

Q: What compliance advantages do the substitute parts offer?

A: Both MF11 series parts are ROHS3 compliant and REACH unaffected, providing regulatory compliance for modern manufacturing standards. The original ERT-D2FGL750S carries MSL 1 (unlimited) moisture sensitivity rating.

Q: Which substitute part should be selected for improved measurement accuracy?

A: MF11-0007505 provides the tightest resistance tolerance at ±5%, compared to ±15% for the original part and ±10% for MF11-0007510. Tolerance selection should align with your circuit's accuracy requirements.
