SCX05DNC Equivalent & Substitute Parts

Part Overview

The SCX05DNC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. It is designed for board mount applications requiring precise pressure measurement in the 5PSI (34.47kPa) range. The sensor outputs a Wheatstone Bridge signal of 0 mV ~ 60 mV at 12V supply voltage and features temperature compensation for stable operation across -40°C to 85°C. The part is currently active in production and RoHS compliant.

Substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits equivalent performance specifications. The SCX05DNC has one qualified equivalent in the Angst+Pfister Sensors and Power AG product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCX05DNC is determined by the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Differential
• Operating Pressure: 5PSI (34.47kPa)
• Output Type: Wheatstone Bridge
• Output Signal: 0 mV ~ 60 mV (12V)
• Port Size: Male - 0.19" (4.8mm) Tube, Dual
• Port Style: Barbed
• Package / Case: 6-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Temperature Compensation: Required

Allowable Parameter Variations:

• Accuracy: ±0.05% to ±0.5% (tighter tolerance acceptable)
• Voltage Supply: 12V ~ 20V (broader range acceptable)
• Maximum Pressure: 20PSI to 25PSI (higher rating acceptable)
• Operating Temperature: -25°C ~ 85°C to -40°C ~ 85°C (narrower range acceptable)
• Manufacturer: Different manufacturers permitted
• Packaging: Bulk or standard packaging acceptable

The PHPSU-4502-005P-D meets all mandatory matching parameters and falls within allowable variations for accuracy, supply voltage, maximum pressure, and operating temperature range.

Engineering Selection Recommendations

SCX05DNC (Honeywell Sensing and Productivity Solutions)

Select the SCX05DNC when:

• Operating temperature range must extend to -40°C (lower limit requirement)
• Accuracy specification of ±0.05% is required
• Honeywell component qualification is mandated by design or procurement standards
• Supply voltage is fixed at 20V
• RoHS compliance and MSL Level 1 (Unlimited) moisture sensitivity are required

PHPSU-4502-005P-D (Angst+Pfister Sensors and Power AG)

Select the PHPSU-4502-005P-D when:

• Operating temperature range of -25°C ~ 85°C is acceptable
• Accuracy tolerance of ±0.5% meets application requirements
• Supply voltage flexibility of 12V ~ 20V is advantageous
• Maximum pressure rating of 25PSI provides additional safety margin
• Angst+Pfister component qualification is acceptable
• Bulk packaging is preferred for inventory management

Both parts are active products with RoHS compliance and equivalent functional performance for differential pressure measurement at 5PSI with Wheatstone Bridge output in 6-SIP module configuration.

Frequently Asked Questions (FAQ)

Q: Can PHPSU-4502-005P-D replace SCX05DNC in all applications?

A: The PHPSU-4502-005P-D is functionally equivalent for applications where operating temperature does not fall below -25°C and accuracy tolerance of ±0.5% is acceptable. If the application requires -40°C operation or ±0.05% accuracy, the SCX05DNC is required.

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

A: The SCX05DNC specifies ±0.05% accuracy, while the PHPSU-4502-005P-D specifies ±0.5% accuracy. Both are suitable for differential pressure measurement at 5PSI, but the SCX05DNC provides tighter tolerance. Application requirements determine which accuracy level is necessary.

Q: Are the port connections identical?

A: Yes. Both sensors feature Male - 0.19" (4.8mm) Tube, Dual barbed ports. Tubing connections are directly interchangeable.

Q: Can I use PHPSU-4502-005P-D at 12V instead of 20V?

A: Yes. The PHPSU-4502-005P-D accepts supply voltage from 12V to 20V. The SCX05DNC is specified at 20V. Verify that your signal conditioning circuit supports the lower supply voltage if using PHPSU-4502-005P-D at 12V.

Q: Are both parts through-hole mounted?

A: Yes. Both the SCX05DNC and PHPSU-4502-005P-D use through-hole mounting with PC pin termination in 6-SIP module packages.

Q: What is the packaging difference?

A: The SCX05DNC is supplied in standard packaging. The PHPSU-4502-005P-D is supplied in bulk packaging. Both are suitable for board mount assembly.

Q: Are both parts RoHS compliant?

A: The SCX05DNC is explicitly RoHS compliant with MSL Level 1 (Unlimited). RoHS compliance status for PHPSU-4502-005P-D is not specified in the provided data. Verify RoHS compliance with the supplier if this is a requirement.
