• Output Type: Wheatstone Bridge
• Port Size: 0.19" (4.83mm) Male Tube, Dual configuration
• Mounting Type: Through Hole, Board Mount
• Termination Style: PC Pin
• Temperature Compensation: Required

Secondary Compatibility Considerations:

• Operating Pressure Range: Must accommodate 0.72PSI (4.98kPa)
• Output Signal Range: 0 mV ~ 20 mV nominal
• Supply Voltage Compatibility: Overlap with 3V ~ 16V range
• Accuracy: ±0.25% or better
• Operating Temperature: Coverage of -25°C ~ 85°C range

The substitute parts listed below meet these criteria with variations in package configuration, port style, and output signal specifications that require evaluation for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

20 INCH-D-MV (Amphenol All Sensors Corporation):

The 20 INCH-D-MV is a direct functional equivalent to the DCXL20DS, matching the operating pressure (0.72PSI), output signal range (0 mV ~ 20 mV at 12V), accuracy (±0.25%), and package configuration (6-SIP Module). Both sensors feature identical port specifications (0.19" male tube, dual configuration) and operating temperature range (-25°C ~ 85°C). The 20 INCH-D-MV is currently in active production status with 1004 units in stock.

Key Differences: The 20 INCH-D-MV features barbless ports compared to the barbed ports of the DCXL20DS, and has a fixed 16V supply voltage specification versus the DCXL20DS range of 3V ~ 16V. The 20 INCH-D-MV carries RoHS non-compliant status, whereas the DCXL20DS is RoHS compliant. The maximum pressure rating is higher at 7.23PSI (49.83kPa) versus 5PSI (34.47kPa).

TSCSNBN001PDUCV (Honeywell Sensing and Productivity Solutions):

The TSCSNBN001PDUCV is a similar substitute from the same manufacturer, maintaining Wheatstone Bridge output type and PC Pin termination. This sensor is currently in active production status with 827 units in stock. The operating pressure range is ±1PSI (±6.89kPa), which encompasses the DCXL20DS operating point of 0.72PSI.

Key Differences: The TSCSNBN001PDUCV uses a 4-SIP package with dual ports on the same side, compared to the 6-SIP module of the DCXL20DS. The output signal is 0 mV ~ 15 mV at 5V supply, requiring signal conditioning adjustments. Port style is barbless. Supply voltage range is 1.5V ~ 12V. Operating temperature extends to -40°C minimum. The accuracy is ±0.2%, superior to the DCXL20DS. Maximum pressure rating is ±12.5PSI (±86.18kPa). RoHS compliant status is maintained.

Compliance Considerations:

For applications requiring RoHS compliance, the TSCSNBN001PDUCV is the preferred substitute. For applications requiring direct pin-for-pin compatibility and identical electrical output characteristics, the 20 INCH-D-MV is the appropriate selection, with the understanding that RoHS compliance status differs.

Frequently Asked Questions (FAQ)

Q: Can the 20 INCH-D-MV be used as a direct replacement for the DCXL20DS?

A: The 20 INCH-D-MV is functionally equivalent for pressure measurement applications within the 0.72PSI operating range. Both sensors provide identical output signal ranges (0 mV ~ 20 mV at 12V), accuracy (±0.25%), and package configuration (6-SIP Module). However, the port style differs (barbless versus barbed), and the supply voltage is fixed at 16V rather than the DCXL20DS range of 3V ~ 16V. Tubing connection compatibility must be verified for the barbless port configuration.

Q: What are the key differences between the 20 INCH-D-MV and TSCSNBN001PDUCV?

A: The 20 INCH-D-MV maintains identical electrical output characteristics to the DCXL20DS (0 mV ~ 20 mV at 12V), while the TSCSNBN001PDUCV outputs 0 mV ~ 15 mV at 5V, requiring signal conditioning. The 20 INCH-D-MV uses a 6-SIP package; the TSCSNBN001PDUCV uses a 4-SIP package with dual ports on the same side. The TSCSNBN001PDUCV has superior accuracy (±0.2% versus ±0.25%) and extended operating temperature range (-40°C to 85°C versus -25°C to 85°C). The TSCSNBN001PDUCV is RoHS compliant; the 20 INCH-D-MV is not.

Q: Is the TSCSNBN001PDUCV suitable for applications requiring RoHS compliance?

A: Yes. The TSCSNBN001PDUCV is RoHS compliant, whereas the DCXL20DS (obsolete) and 20 INCH-D-MV are not compliant or have non-compliant status. For new designs or applications with RoHS requirements, the TSCSNBN001PDUCV is the appropriate selection.

Q: What is the impact of the different output signal ranges?

A: The DCXL20DS and 20 INCH-D-MV both output 0 mV ~ 20 mV at 12V supply. The TSCSNBN001PDUCV outputs 0 mV ~ 15 mV at 5V supply. This difference requires adjustment of signal conditioning circuits and analog-to-digital converter scaling. The lower output voltage of the TSCSNBN001PDUCV may provide improved noise immunity in some applications but requires recalibration of measurement systems.

Q: Are the port connections compatible between these sensors?

A: All three sensors feature 0.19" (4.83mm or 4.8mm) male tube ports in dual configuration. The DCXL20DS and 20 INCH-D-MV have identical port sizes (4.83mm). The TSCSNBN001PDUCV port size is 4.8mm, a negligible difference. However, the DCXL20DS uses barbed ports while the 20 INCH-D-MV and TSCSNBN001PDUCV use barbless ports. Tubing compatibility must be verified based on the specific tubing specifications and connection method used in the application.

Q: What is the significance of the maximum pressure ratings?

A: The DCXL20DS has a maximum pressure rating of 5PSI (34.47kPa), the 20 INCH-D-MV has 7.23PSI (49.83kPa), and the TSCSNBN001PDUCV has ±12.5PSI (±86.18kPa). These ratings define the overpressure protection limits. For applications operating at or near the 0.72PSI nominal pressure, all three sensors provide adequate overpressure margin. Applications with potential pressure spikes must verify that the selected sensor's maximum pressure rating accommodates the system's worst-case pressure conditions.

Q: Can the TSCSNBN001PDUCV operate with the same supply voltage as the DCXL20DS?

A: The DCXL20DS operates at 3V ~ 16V supply. The TSCSNBN001PDUCV operates at 1.5V ~ 12V supply. The overlap range is 3V ~ 12V. At 12V supply, both sensors function within specification. However, the TSCSNBN001PDUCV output signal at 12V supply will be lower than at its nominal 5V, requiring verification that the signal conditioning circuit can accommodate the reduced output voltage.

Q: What inventory availability should be considered?

A: The DCXL20DS has 1700 units in stock (obsolete status). The 20 INCH-D-MV has 1004 units in stock (active status). The TSCSNBN001PDUCV has 827 units in stock (active status). For long-term supply chain planning, the active status parts (20 INCH-D-MV and TSCSNBN001PDUCV) are preferable to the obsolete DCXL20DS.
