NTPA75R0LBMB0 Equivalent & Substitute Parts

Part Overview

The NTPA75R0LBMB0 is an NTC thermistor manufactured by Murata Electronics with a nominal resistance of 5 ohms at 25°C in a disc 7mm package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part operates across a temperature range of -20°C to 160°C and is RoHS3 compliant with MSL 1 rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NTPA75R0LBMB0 is based on the following critical parameters:

• Resistance value: 5 ohms nominal
• Resistance tolerance: ±15% to ±20% acceptable range
• Operating temperature range: -20°C to 160°C minimum
• Package compatibility: Through-hole mounting, disc form factor
• Regulatory compliance: RoHS3 compliant, MSL 1 rating
• Electrical classification: NTC thermistor or equivalent inrush current limiting device

The substitute part B57235S0509M000 meets these criteria as a 5-ohm component with ±20% tolerance, through-hole mounting, and equivalent regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The B57235S0509M000 serves as a direct functional substitute for the obsolete NTPA75R0LBMB0 based on matching resistance specifications and regulatory compliance. Both components share identical ROHS3 compliance status, MSL 1 rating, and ECCN/HTSUS classification, ensuring procurement and regulatory continuity.

The primary design consideration is package geometry: the B57235S0509M000 features a 9.5mm diameter compared to the 7mm disc of the original part. Physical space constraints in the application must be evaluated before substitution. The tolerance difference (±20% versus ±15%) is acceptable for most thermal sensing applications where the 5-ohm nominal value is the primary functional requirement.

Frequently Asked Questions (FAQ)

Q: Can B57235S0509M000 directly replace NTPA75R0LBMB0 in all applications?

A: Electrical substitution is valid based on matching 5-ohm resistance and tolerance specifications. Physical board layout must accommodate the larger 9.5mm package diameter of the substitute part.

Q: What is the significance of the ±20% tolerance on the substitute versus ±15% on the original?

A: The wider tolerance on B57235S0509M000 represents a less stringent specification. Applications requiring the tighter ±15% tolerance must evaluate whether the ±20% tolerance meets circuit performance requirements.

Q: Are both parts suitable for the same temperature operating range?

A: The NTPA75R0LBMB0 specifies -20°C to 160°C operation. The B57235S0509M000 specifications provided do not include explicit temperature range data; thermal performance must be verified against application requirements.

Q: What are the lead spacing differences between these components?

A: The B57235S0509M000 specifies 0.197" (5.00mm) lead spacing. Original part lead spacing is not provided in available documentation. PCB footprint compatibility must be confirmed before substitution.

Q: Do both parts maintain equivalent regulatory compliance?

A: Yes. Both components are ROHS3 compliant, carry MSL 1 rating, and share identical ECCN (EAR99) and HTSUS (8533.40.8070) classifications.
