Key Parameters

Substitute Part Grouping Explanation

Substitution of the XPX01D is determined by the following critical parameters:

Pressure Specification: Operating pressure range must accommodate the 1PSI (6.89kPa) differential requirement. The substitute part NSCSMNN001PDUNV operates at ±1PSI (±6.89kPa) differential, providing equivalent pressure measurement capability.

Output Characteristics: Both the main part and substitute utilize Wheatstone Bridge output topology. The XPX01D outputs 0 mV to 75 mV at 5V supply, while NSCSMNN001PDUNV outputs 0 mV to 65 mV at 5V supply. Both operate within compatible supply voltage ranges (XPX01D: 3V ~ 12V; NSCSMNN001PDUNV: 1.5V ~ 12V).

Package and Mounting: Both parts are housed in 4-SIP Module packages with PC Pin termination and through-hole mounting, ensuring mechanical and electrical compatibility on existing PCB designs.

Regulatory Compliance: Both parts are RoHS Compliant with MSL 1 (Unlimited) rating and carry identical HTSUS and ECCN classifications.

Product Status Consideration: The XPX01D is obsolete, while NSCSMNN001PDUNV is active production, making it the primary substitute for continued supply assurance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: NSCSMNN001PDUNV is the recommended substitute for XPX01D applications. Both parts are manufactured by Honeywell and share identical package, termination, and mounting specifications. The substitute is RoHS Compliant and carries the same regulatory classifications (ECCN: EAR99; HTSUS: 9026.20.4000).

Compliance Status: Both parts meet RoHS requirements and carry MSL 1 (Unlimited) ratings, ensuring compatibility with standard PCB assembly processes. REACH status is unaffected for both parts.

Production Continuity: The XPX01D is obsolete, while NSCSMNN001PDUNV is in active production with confirmed inventory availability (787 Pcs New Original In Stock). This ensures long-term supply assurance for new designs and system replacements.

Performance Advantages: The NSCSMNN001PDUNV offers improved accuracy (±0.25% versus ±1%), extended temperature range (-40°C minimum versus -25°C), and higher overpressure rating (±10PSI versus 3PSI), providing enhanced performance margins for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can NSCSMNN001PDUNV directly replace XPX01D in existing designs?

A: Yes. Both parts use identical 4-SIP Module packaging with PC Pin termination and through-hole mounting. Electrical compatibility is confirmed through matching Wheatstone Bridge output topology and overlapping supply voltage ranges (3V ~ 12V operational window). The 10 mV output difference (75 mV versus 65 mV at 5V) requires signal conditioning verification in the receiving circuit.

Q: What is the output voltage difference between these parts?

A: XPX01D outputs 0 mV to 75 mV at 5V supply, while NSCSMNN001PDUNV outputs 0 mV to 65 mV at 5V supply. This 10 mV difference represents approximately 13% variation in full-scale output. Analog-to-digital converter (ADC) scaling and calibration must account for this difference.

Q: Are there temperature range differences?

A: Yes. XPX01D operates from -25°C to 85°C, while NSCSMNN001PDUNV operates from -40°C to 85°C. The substitute supports 15°C lower minimum temperature, providing expanded operational capability for cold environment applications.

Q: What is the accuracy improvement?

A: XPX01D specifies ±1% accuracy, while NSCSMNN001PDUNV specifies ±0.25% accuracy. The substitute provides four times better accuracy, reducing measurement uncertainty in pressure monitoring applications.

Q: Are both parts RoHS Compliant?

A: Yes. Both XPX01D and NSCSMNN001PDUNV are RoHS Compliant with MSL 1 (Unlimited) ratings. Both carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications.

Q: What is the maximum pressure rating difference?

A: XPX01D is rated for 3PSI (20.68kPa) maximum pressure, while NSCSMNN001PDUNV is rated for ±10PSI (±68.95kPa). The substitute provides significantly higher overpressure protection, suitable for applications with pressure transient events.

Q: Is the supply voltage range compatible?

A: Both parts operate within the 3V to 12V range. XPX01D specifies 3V ~ 12V, while NSCSMNN001PDUNV specifies 1.5V ~ 12V. The substitute supports lower minimum supply voltage, enabling operation in battery-powered or low-voltage applications.
