CPC01DFC Equivalent & Substitute Parts Reference

Part Overview

The CPC01DFC is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 1PSI (6.89kPa) operating pressure range. This component features a Wheatstone Bridge output configuration with 0 mV ~ 18 mV (12V) signal output and is housed in a 4-SIP module package with barbed male tube ports (0.16" / 4.06mm dual configuration).

The CPC01DFC is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and new production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPC01DFC are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Pressure Type: Differential
• Output Type: Wheatstone Bridge
• Package Type: 4-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Temperature Compensation: Required

Secondary Compatibility Parameters:

• Operating Pressure Range: Must accommodate 1PSI (6.89kPa) differential measurement
• Output Signal Range: Must be compatible with 0 mV ~ 18 mV (12V) or equivalent signal conditioning
• Supply Voltage: Must overlap with 3V ~ 16V range
• Port Style: Barbed or barbless male tube configuration acceptable
• Operating Temperature: Must support -25°C ~ 85°C minimum range

Two substitute parts meet these criteria with documented compatibility:

1. TSCSAAN001PDUCV (Honeywell Sensing and Productivity Solutions) - Active product status, enhanced accuracy specification
2. 1 PSI-D-CGRADE-MINI (Amphenol All Sensors Corporation) - Active product status, direct pressure range match

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 1 PSI-D-CGRADE-MINI (Amphenol All Sensors Corporation) provides the closest functional match to the CPC01DFC. Both components share identical operating pressure (1PSI / 6.89kPa), output signal range (0 mV ~ 18 mV at 12V), and operating temperature limits (-25°C ~ 85°C). The 1 PSI-D-CGRADE-MINI is currently in active production status with RoHS compliance certification. Port size variation (0.18" vs. 0.16") and barbless configuration require mechanical interface verification but do not affect electrical performance. The improved accuracy specification (±1% vs. ±2%) provides enhanced measurement precision.

For Enhanced Performance Applications:

The TSCSAAN001PDUCV (Honeywell Sensing and Productivity Solutions, TruStability® TSC series) offers superior accuracy (±0.2% vs. ±2%) and extended maximum pressure rating (±12.5PSI vs. 5PSI). This component is suitable for applications requiring higher measurement precision and broader pressure headroom. The extended operating temperature range (-40°C ~ 85°C) supports wider environmental conditions. Port size (0.19" vs. 0.16") and output signal range (0 mV ~ 15 mV at 5V) require circuit-level signal conditioning evaluation. Active product status ensures long-term supply availability.

Compliance Considerations:

All three components (CPC01DFC, TSCSAAN001PDUCV, 1 PSI-D-CGRADE-MINI) maintain RoHS compliance and Moisture Sensitivity Level 1 (Unlimited) classification. ECCN and HTSUS codes are identical across all parts, confirming regulatory equivalence for export and procurement purposes.

Frequently Asked Questions (FAQ)

Q: Can the TSCSAAN001PDUCV directly replace the CPC01DFC without circuit modifications?

A: The TSCSAAN001PDUCV requires signal conditioning evaluation. The output range differs (0 mV ~ 15 mV at 5V vs. 0 mV ~ 18 mV at 12V), necessitating amplifier or analog-to-digital converter recalibration. Port size (0.19" vs. 0.16") requires mechanical interface verification. Electrical substitution is feasible with appropriate signal chain adjustments.

Q: What are the mechanical compatibility considerations for the 1 PSI-D-CGRADE-MINI?

A: The 1 PSI-D-CGRADE-MINI features a 0.18" (4.57mm) male tube port versus the CPC01DFC's 0.16" (4.06mm) port. Tubing adapters or port fittings may be required depending on existing pneumatic connections. The barbless port style differs from the CPC01DFC's barbed configuration; verify tubing retention method compatibility with your application's pneumatic interface design.

Q: Which substitute part offers the best long-term supply availability?

A: Both the TSCSAAN001PDUCV and 1 PSI-D-CGRADE-MINI are classified as active products with documented inventory levels (1015 Pcs and 724 Pcs respectively). The TSCSAAN001PDUCV, as part of Honeywell's TruStability® TSC series, represents a current-generation product line with established market presence. The 1 PSI-D-CGRADE-MINI, manufactured by Amphenol All Sensors Corporation, provides an alternative active source. Both support extended production lifecycles compared to the obsolete CPC01DFC.

Q: Are there accuracy trade-offs when selecting a substitute?

A: The CPC01DFC specifies ±2% accuracy. The 1 PSI-D-CGRADE-MINI provides ±1% accuracy, representing improved measurement precision without performance degradation. The TSCSAAN001PDUCV offers ±0.2% accuracy, a significant enhancement suitable for precision measurement applications. Accuracy improvements do not create compatibility issues; they enhance system performance.

Q: What is the impact of different maximum pressure ratings?

A: The CPC01DFC maximum pressure is 5PSI (34.47kPa). The 1 PSI-D-CGRADE-MINI supports 10PSI (68.95kPa), and the TSCSAAN001PDUCV supports ±12.5PSI (±86.18kPa). Higher maximum pressure ratings provide additional safety margin and overpressure protection. This parameter does not restrict substitution; it indicates enhanced component robustness.

Q: How do supply voltage ranges affect circuit design?

A: The CPC01DFC operates on 3V ~ 16V supply. The 1 PSI-D-CGRADE-MINI requires 16V fixed supply, which is within the CPC01DFC range but less flexible. The TSCSAAN001PDUCV operates on 1.5V ~ 12V, requiring voltage regulator adjustment if your circuit supplies 16V. Verify power supply specifications before substitution to ensure compatibility with existing voltage rails.

Q: Is the 4-SIP package configuration identical across all three parts?

A: All three components use 4-SIP module packaging with through-hole PC pin termination. The TSCSAAN001PDUCV specifies "4-SIP, Dual Ports, Opposite Sides" configuration, indicating port placement on opposite sides of the module. Verify PCB layout compatibility, particularly if existing designs assume specific port orientation. Pin-to-pin electrical compatibility is maintained across all variants.
