SCX01DNC Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The SCX01DNC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring precise pressure measurement in the 1PSI (6.89kPa) range. This sensor outputs a Wheatstone Bridge signal of 0 mV to 18 mV at 12V supply, with ±1% accuracy and temperature compensation across the -40°C to 85°C operating range. The part is actively produced and RoHS compliant with MSL Level 1 rating.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same functional and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCX01DNC are qualified based on the following critical parameters that must align with the main part specification:

Mandatory Matching Parameters:

• Pressure Type: Differential
• Operating Pressure: 1PSI (6.89kPa)
• Output Type: Wheatstone Bridge
• Output Range: 0 mV ~ 18 mV (12V)
• Port Size: Male - 0.19" (4.8mm) Tube, Dual
• Port Style: Barbed
• Package / Case: 6-SIP
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Temperature Compensation: Required

Allowable Parameter Variations:

• Accuracy: ±1% or better (tighter tolerance acceptable)
• Supply Voltage: 12V ~ 20V range (accommodates both 12V and 20V operation)
• Operating Temperature: -25°C ~ 85°C or wider (narrower range acceptable if application permits)
• Maximum Pressure: 10PSI or higher (higher rating acceptable)

The PHPSU-4502-001P-D from Angst+Pfister Sensors and Power AG qualifies as a substitute part because it meets all mandatory parameters and operates within allowable variations for accuracy, supply voltage, and maximum pressure rating.

Parameter Comparison

Engineering Selection Recommendations

SCX01DNC Selection Criteria:

• Primary choice when -40°C lower temperature limit is required
• Preferred when maximum pressure rating of 20PSI is a system requirement
• Recommended for applications requiring RoHS compliance certification documentation
• 2100 units currently in stock

PHPSU-4502-001P-D Selection Criteria:

• Acceptable substitute when operating temperature minimum of -25°C meets application requirements
• Suitable when maximum pressure exposure does not exceed 10PSI
• Provides improved accuracy specification (±0.5% vs ±1%)
• Supports flexible supply voltage range (12V ~ 20V)
• 928 units currently in stock

Both parts are active products with confirmed availability. Selection between them depends on specific application temperature and pressure envelope requirements, not on functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can PHPSU-4502-001P-D replace SCX01DNC in all applications?

A: The PHPSU-4502-001P-D is functionally compatible for applications where the operating temperature does not fall below -25°C and maximum pressure exposure remains below 10PSI. If your application requires the -40°C lower limit or operates near 20PSI maximum pressure, the SCX01DNC is the required choice.

Q: What is the difference in accuracy between these two sensors?

A: The SCX01DNC specifies ±1% accuracy, while the PHPSU-4502-001P-D specifies ±0.5% accuracy. The substitute part provides tighter accuracy tolerance, which is compatible with applications designed for the main part's ±1% specification.

Q: Are the 6-SIP packages identical between manufacturers?

A: Both parts use 6-SIP through-hole mounting with PC pin termination. The PHPSU-4502-001P-D is designated as a 6-SIP Module, but maintains identical mechanical compatibility for board mount applications.

Q: What supply voltage should I use with each part?

A: The SCX01DNC operates at 20V supply. The PHPSU-4502-001P-D accepts 12V to 20V supply voltage. Both produce the same 0 mV to 18 mV output range at 12V operation, ensuring signal compatibility in systems using either voltage level.

Q: Which part should I specify for new designs?

A: For new designs, evaluate your application's temperature and pressure requirements. If operation below -25°C or above 10PSI maximum pressure is required, specify SCX01DNC. If your application operates within -25°C to 85°C and below 10PSI, either part is acceptable; PHPSU-4502-001P-D offers improved accuracy.

Q: Are both parts RoHS compliant?

A: The SCX01DNC is confirmed RoHS compliant. RoHS compliance status for PHPSU-4502-001P-D is not specified in available documentation.
