SCX30DN Equivalent & Substitute Parts Reference

Part Overview

The SCX30DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This 6-SIP module device measures pressure differentials up to 30 PSI (206.84 kPa) with a Wheatstone Bridge output of 0 mV to 90 mV at 12V supply. The sensor features temperature compensation, barbed male tube ports (0.19" / 4.8mm dual configuration), and PC pin termination for through-hole mounting on printed circuit boards.

The SCX30DN maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified for applications requiring equivalent pressure measurement capabilities, identical output characteristics, or compatible mechanical interfaces within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCX30DN are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Pressure Type: Differential
• Operating Pressure: 30 PSI (206.84 kPa)
• Output Type: Wheatstone Bridge
• Output Range: 0 mV ~ 90 mV (12V)
• Package Type: 6-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Port Configuration: Male tube, dual configuration

Secondary Compatibility Parameters:

• Port size tolerance: 0.19" nominal (4.8 mm ± 0.03 mm acceptable)
• Temperature compensation: Required
• Supply voltage: 12V to 20V range acceptable
• Accuracy: ±1% or better
• Operating temperature: Minimum -25°C to 85°C acceptable

The identified substitute parts meet these criteria while maintaining equivalent pressure measurement functionality and circuit board integration characteristics.

Parameter Comparison

Engineering Selection Recommendations

SCX30DN (Honeywell Sensing and Productivity Solutions)

Primary selection for applications requiring the extended operating temperature range of -40°C to 85°C. RoHS Compliant status with unlimited MSL rating (1) supports long-term storage and high-reliability applications. Maximum pressure rating of 60 PSI provides adequate overpressure protection for 30 PSI nominal operation. Barbed port configuration ensures secure tubing attachment.

30 PSI-D-CGRADE-MV (Amphenol All Sensors Corporation)

Suitable for applications operating within -25°C to 85°C temperature range. ROHS3 Compliant designation indicates enhanced environmental compliance. Higher maximum pressure rating (90 PSI) provides increased overpressure margin. Barbless port design offers alternative tubing interface characteristics. Supply voltage requirement of 16V is compatible with standard industrial power supplies. Tube packaging format supports alternative inventory management approaches.

PHPSU-4502-030P-D-SP (Angst+Pfister Sensors and Power AG)

Applicable for applications requiring improved accuracy specification (±0.5% versus ±1%). Wide supply voltage range (12V to 20V) accommodates diverse power distribution architectures. Maximum pressure rating of 90 PSI matches Amphenol substitute. Barbed port configuration aligns with SCX30DN mechanical interface. Bulk packaging format supports high-volume procurement. Operating temperature range of -25°C to 85°C meets standard industrial requirements.

Frequently Asked Questions (FAQ)

Q: Can the 30 PSI-D-CGRADE-MV replace the SCX30DN in all applications?

A: The 30 PSI-D-CGRADE-MV is functionally equivalent for applications operating within -25°C to 85°C. Applications requiring operation below -25°C must use the SCX30DN, which operates to -40°C. The barbless port style differs from the SCX30DN barbed configuration; tubing attachment methods must be verified for your specific application.

Q: What is the significance of the port style difference (barbed versus barbless)?

A: Barbed ports (SCX30DN, PHPSU-4502-030P-D-SP) use mechanical barbs to retain tubing through friction and deformation. Barbless ports (30 PSI-D-CGRADE-MV) require alternative retention methods such as hose clamps or compression fittings. Tubing diameter and material compatibility must be confirmed for your application.

Q: Are all three parts compatible with 12V supply voltage?

A: The SCX30DN requires 20V supply. The 30 PSI-D-CGRADE-MV requires 16V supply. The PHPSU-4502-030P-D-SP accepts 12V to 20V supply range. Verify your circuit design supply voltage before part selection.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates conformance to the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates conformance to the updated directive (2011/65/EU). Both designations restrict hazardous substances; ROHS3 represents the current regulatory standard. The PHPSU-4502-030P-D-SP RoHS status is not specified in available documentation.

Q: Can I use the PHPSU-4502-030P-D-SP for improved accuracy?

A: The PHPSU-4502-030P-D-SP offers ±0.5% accuracy compared to ±1% for the SCX30DN and 30 PSI-D-CGRADE-MV. This improved accuracy is available within the same 6-SIP package and output range. Verify that your circuit design and signal conditioning can utilize the improved accuracy specification.

Q: What is the maximum pressure rating significance?

A: The SCX30DN maximum pressure is 60 PSI; both substitute parts are rated to 90 PSI. Higher maximum pressure ratings provide greater overpressure protection margin. For 30 PSI nominal operation, all three parts provide adequate safety margin.

Q: Are the 6-SIP module pinouts identical across all three parts?

A: All three parts use 6-SIP module packaging with PC pin termination for through-hole mounting. Pinout compatibility must be verified against your specific circuit board design and the manufacturer's detailed pinout documentation.
