CPCL04DFC Equivalent & Substitute Parts Reference

Part Overview

The CPCL04DFC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component operates at 0.15PSI (1kPa) differential pressure with a Wheatstone Bridge output of 0 mV ~ 25 mV at 12V supply. The CPCL04DFC features a male barbed tube port (0.16" / 4.06mm dual configuration) and is mounted through-hole in a 4-SIP module package with PC pin termination.

The CPCL04DFC is classified as obsolete. Locating equivalent and substitute parts is necessary to support legacy system maintenance, design updates, and procurement continuity. Active alternative models from Honeywell and compatible manufacturers provide equivalent or enhanced performance characteristics while maintaining design compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPCL04DFC is determined by the following critical parameters:

Primary Compatibility Criteria:

• Pressure Type: Differential
• Operating Pressure: 0.15PSI (1kPa) or ±0.15PSI (±1kPa)
• Mounting Type: Through Hole
• Package / Case: 4-SIP Module configuration
• Termination Style: PC Pin
• Port Style: Barbed or equivalent mechanical interface
• RoHS Compliance: RoHS Compliant

Secondary Compatibility Considerations:

• Output Type: Wheatstone Bridge or Analog Voltage (both acceptable for differential pressure measurement)
• Supply Voltage: Must overlap with or encompass the 3V ~ 16V range
• Operating Temperature: Must support -25°C ~ 85°C minimum
• Accuracy: ±2% or better

Substitute parts are grouped into two categories:

Category 1 - Honeywell Active Series (Enhanced Performance): NSCSAAN004NDUNV and SSCSAAN004NDAA5 represent active product lines with improved accuracy (±0.25%), extended pressure ratings, and broader operating temperature ranges (-40°C ~ 85°C). These parts maintain the 4-SIP through-hole configuration and PC pin termination while offering superior specifications.

Category 2 - Cross-Manufacturer Direct Equivalent: 4 INCH-D-CGRADE-MINI from Amphenol All Sensors Corporation provides functional equivalence with identical pressure rating, output type, and package configuration. Minor variations in port size (0.18" vs. 0.16") and port style (barbless vs. barbed) require mechanical interface verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Obsolete Part Substitution):

The 4 INCH-D-CGRADE-MINI from Amphenol All Sensors Corporation provides the closest functional equivalence to the CPCL04DFC. Both components share identical pressure ratings (0.15PSI differential), output type (Wheatstone Bridge), output range (0 mV ~ 25 mV at 12V), package configuration (4-SIP through-hole), and termination style (PC pin). The port size variation (0.18" vs. 0.16") and port style difference (barbless vs. barbed) require mechanical interface assessment but do not affect electrical compatibility. This part is currently active and RoHS compliant.

For Enhanced Performance Applications:

The SSCSAAN004NDAA5 (Honeywell TruStability® SSC series) offers superior accuracy (±0.25% vs. ±2%), amplified analog voltage output (0.5 V ~ 4.5 V), and extended maximum pressure rating (±10.84PSI vs. 3PSI). This part maintains 4-SIP through-hole mounting and PC pin termination. The supply voltage requirement (4.95V ~ 5.05V) is narrower than the CPCL04DFC but falls within the original operating range. This substitution is suitable for designs requiring improved measurement precision and pressure headroom.

For Wheatstone Bridge Output Preservation:

The NSCSAAN004NDUNV (Honeywell TruStability® NSC series) maintains Wheatstone Bridge output architecture with enhanced accuracy (±0.25%). This part supports a broader supply voltage range (2.7V ~ 6.5V) and extended operating temperature (-40°C ~ 85°C). The port size (0.19" vs. 0.16") requires mechanical interface verification. This substitution is appropriate for applications prioritizing output type consistency.

All substitute parts are RoHS compliant and carry active product status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q1: Can the SSCSAAN004NDAA5 replace the CPCL04DFC in existing designs?

The SSCSAAN004NDAA5 is electrically compatible with the CPCL04DFC at the board level. Both use 4-SIP through-hole mounting with PC pin termination. However, the output type differs: SSCSAAN004NDAA5 provides amplified analog voltage (0.5 V ~ 4.5 V) rather than Wheatstone Bridge output (0 mV ~ 25 mV). This requires signal conditioning circuit modifications. The supply voltage requirement (4.95V ~ 5.05V) is more restrictive than the CPCL04DFC (3V ~ 16V). Mechanical interface compatibility must be verified due to port size differences (0.19" vs. 0.16").

Q2: What are the mechanical interface considerations when substituting the 4 INCH-D-CGRADE-MINI?

The 4 INCH-D-CGRADE-MINI has a port size of 0.18" (4.57mm) compared to the CPCL04DFC's 0.16" (4.06mm). The port style differs: 4 INCH-D-CGRADE-MINI uses barbless ports while CPCL04DFC uses barbed ports. These differences affect tubing connection methods and may require adapter fittings or tubing specification changes. Electrical and functional performance are equivalent. Verify tubing compatibility and connection integrity before deployment.

Q3: Why does the NSCSAAN004NDUNV have a different port size?

The NSCSAAN004NDUNV uses a 0.19" (4.93mm) male barbed tube port compared to the CPCL04DFC's 0.16" (4.06mm). This represents a design evolution in the Honeywell TruStability® NSC series. The larger port size accommodates higher pressure ratings (±9.76PSI vs. 3PSI) and improved performance specifications. Tubing compatibility must be verified; adapter fittings may be required for direct substitution in existing pneumatic systems.

Q4: Is the CPCL04DFC truly obsolete, and what does this mean for procurement?

The CPCL04DFC is classified as obsolete by Honeywell, indicating discontinued manufacturing and limited future availability. Current inventory is reported at 787 pieces. For new designs or long-term production, substitution to active parts (SSCSAAN004NDAA5, NSCSAAN004NDUNV, or 4 INCH-D-CGRADE-MINI) is recommended to ensure supply chain continuity and access to technical support.

Q5: Which substitute part offers the best accuracy improvement?

Both SSCSAAN004NDAA5 and NSCSAAN004NDUNV provide ±0.25% accuracy compared to the CPCL04DFC's ±2%. The SSCSAAN004NDAA5 additionally offers amplified analog voltage output with temperature compensation, making it suitable for applications requiring high-precision differential pressure measurement. The NSCSAAN004NDUNV preserves Wheatstone Bridge output for designs requiring minimal signal conditioning modifications.

Q6: Can I use the substitute parts interchangeably in the same PCB footprint?

All substitute parts use 4-SIP through-hole mounting with PC pin termination, making them mechanically compatible at the PCB level. However, electrical signal characteristics differ: SSCSAAN004NDAA5 outputs analog voltage (0.5 V ~ 4.5 V) while CPCL04DFC and NSCSAAN004NDUNV output Wheatstone Bridge signals (0 mV ~ 25 mV range). Signal conditioning and amplification circuits must be adapted accordingly. Verify supply voltage compatibility with your power distribution design.

Q7: What is the temperature operating range difference, and does it matter?

The CPCL04DFC operates from -25°C to 85°C. The SSCSAAN004NDAA5 and NSCSAAN004NDUNV extend the lower limit to -40°C. This extended range is beneficial for applications in cold environments or outdoor installations. If your application operates within -25°C to 85°C, all parts are functionally equivalent in this parameter. For cold-temperature applications, the Honeywell TruStability® series provides additional margin.

Q8: Are all substitute parts RoHS compliant?

Yes. The CPCL04DFC, SSCSAAN004NDAA5, NSCSAAN004NDUNV, and 4 INCH-D-CGRADE-MINI are all RoHS compliant. All parts carry MSL 1 (Unlimited) moisture sensitivity classification and are suitable for standard PCB assembly processes without special handling requirements.
