DUXL01D Equivalent & Substitute Parts Reference

Part Overview

The DUXL01D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 0.04PSI (0.25kPa) operating pressure range. The sensor outputs a Wheatstone Bridge signal of 0 mV ~ 6 mV at 4.5V supply voltage and features male barbed tube ports of 0.08" (2.03mm) diameter in a 4-SIP module configuration.

This part is classified as Obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The following substitute parts maintain functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DUXL01D are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Pressure Type: Differential
• Operating Pressure Range: 0.04PSI (0.25kPa) nominal
• Output Type: Wheatstone Bridge
• Termination Style: PC Pin
• Mounting Type: Through Hole
• Package Configuration: 4-SIP Module

Secondary Compatibility Considerations:

• Supply Voltage Range (must overlap with 3V ~ 8V)
• Operating Temperature Range (must cover -25°C ~ 85°C minimum)
• Port Configuration: Male barbed tube ports, dual configuration
• Output Signal Compatibility: Voltage output in mV range at specified supply voltage

The substitute parts listed below satisfy the primary compatibility criteria and maintain electrical and mechanical interchangeability within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

NSCSDRN001NDUNV (Honeywell TruStability® NSC Series)

This substitute maintains Honeywell manufacturer continuity and shares the same differential pressure operating range (±0.04PSI / ±0.25kPa). The part features improved accuracy (±0.25% vs. ±0.5%) and extended maximum pressure rating (9.76PSI vs. 3.61PSI). Supply voltage range (2.7V ~ 6.5V) overlaps with the DUXL01D specification (3V ~ 8V). Operating temperature range extends to -40°C, exceeding the original -25°C minimum.

Mechanical Consideration: Port size differs (0.19" vs. 0.08" tube diameter), requiring tubing adapter evaluation for existing pneumatic connections. Package configuration specifies dual ports on opposite sides, which may require PCB layout verification.

Compliance: Product status is Obsolete; RoHS compliance status not specified in available data.

1 INCH-D1-BASIC (Amphenol All Sensors ADUX Series)

This substitute is manufactured by Amphenol All Sensors Corporation and maintains active product status, ensuring ongoing availability and support. Operating pressure (0.04PSI / 0.25kPa) and output type (Wheatstone Bridge) match the DUXL01D specification. Output signal (0 mV ~ 7 mV at 4.5V) is within 1 mV of the original specification. Port size (0.08" / 2.13mm tube) is dimensionally equivalent to the DUXL01D (0.08" / 2.03mm), minimizing pneumatic interface modifications.

Electrical Consideration: Supply voltage is fixed at 6V, within the DUXL01D range (3V ~ 8V). Accuracy specification (±1%) is less stringent than the original (±0.5%).

Mechanical Consideration: Port style is barbless, differing from the original barbed configuration. This may affect tubing retention characteristics and require mechanical interface review.

Compliance: Product status is Active. RoHS non-compliant status must be evaluated against system requirements.

Frequently Asked Questions (FAQ)

Q: Can NSCSDRN001NDUNV be used as a direct replacement for DUXL01D?

A: NSCSDRN001NDUNV maintains functional compatibility in pressure range, output type, and electrical interface. However, the port size differs (0.19" vs. 0.08" tube diameter), requiring tubing adapter specification. Dual ports on opposite sides may require PCB layout verification. Accuracy improvement (±0.25% vs. ±0.5%) is beneficial for system performance.

Q: What are the pneumatic interface differences between DUXL01D and 1 INCH-D1-BASIC?

A: Port tube diameters are nominally equivalent (0.08" / 2.03mm vs. 0.08" / 2.13mm). The primary difference is port style: DUXL01D features barbed ports for mechanical tubing retention, while 1 INCH-D1-BASIC features barbless ports. Tubing retention method must be re-evaluated for the barbless configuration.

Q: Which substitute part is recommended for new designs?

A: 1 INCH-D1-BASIC is recommended for new designs due to active product status, ensuring long-term availability and manufacturer support. NSCSDRN001NDUNV is suitable for legacy system maintenance where Honeywell manufacturer continuity is required.

Q: Are there supply voltage compatibility issues with these substitutes?

A: DUXL01D operates at 3V ~ 8V. NSCSDRN001NDUNV operates at 2.7V ~ 6.5V (compatible within overlap range 3V ~ 6.5V). 1 INCH-D1-BASIC operates at fixed 6V (within DUXL01D range). System power supply specifications must be verified to ensure compatibility.

Q: What is the impact of accuracy differences between these parts?

A: DUXL01D specifies ±0.5% accuracy. NSCSDRN001NDUNV specifies ±0.25% (improved). 1 INCH-D1-BASIC specifies ±1% (reduced). System measurement requirements must be evaluated to determine acceptable accuracy tolerance for the application.

Q: Are there RoHS compliance considerations for substitution?

A: DUXL01D is RoHS Compliant. NSCSDRN001NDUNV RoHS status is not specified. 1 INCH-D1-BASIC is RoHS non-compliant. System environmental and regulatory requirements must be reviewed to determine compliance necessity.

Q: What is the operating temperature range compatibility?

A: DUXL01D operates at -25°C ~ 85°C. NSCSDRN001NDUNV operates at -40°C ~ 85°C (extended low-temperature range). 1 INCH-D1-BASIC operates at -25°C ~ 85°C (equivalent). System thermal environment specifications must be verified.
