Substitute Part Grouping Explanation

Substitution of the obsolete CPC0.3DFH requires identification of active pressure sensor alternatives that maintain compatibility across critical electrical and mechanical parameters. The primary substitute identified is the TSCSAAN001PDUCV from Honeywell's TruStability® TSC series.

Substitution logic is based on the following allowable parameter alignment:

Electrical Compatibility Parameters:

• Output Type: Wheatstone Bridge (maintained)
• Termination Style: PC Pin (maintained)
• Mounting Type: Through Hole (maintained)
• Package Type: 4-SIP Module (maintained)
• Temperature Compensation: Present in both designs
• RoHS Compliance: Both parts RoHS Compliant

Mechanical Compatibility Parameters:

• Port Style: Barbed (maintained)
• Dual Port Configuration: Present in both designs
• Supply Voltage Range: Overlapping operational envelope (3V ~ 16V for CPC0.3DFH; 1.5V ~ 12V for TSCSAAN001PDUCV)

Pressure Measurement Parameters:

• Pressure Type: Differential (maintained)
• Operating Pressure Range: Different nominal values (0.3PSI vs. ±1PSI) but within maximum pressure specifications
• Maximum Pressure Rating: TSCSAAN001PDUCV rated to ±12.5PSI, exceeding CPC0.3DFH maximum of 5PSI

The TSCSAAN001PDUCV represents an active product with enhanced specifications, including improved accuracy (±0.2% vs. ±2%), extended temperature range (-40°C ~ 85°C vs. -25°C ~ 85°C), and higher maximum pressure capability.

Engineering Selection Recommendations

The TSCSAAN001PDUCV is the identified substitute for the obsolete CPC0.3DFH. Selection of this alternative is supported by the following engineering criteria:

Product Status Alignment: The CPC0.3DFH is classified as obsolete, making continued procurement impossible. The TSCSAAN001PDUCV maintains active product status with full manufacturer support and availability.

Compliance and Certification: Both parts maintain RoHS Compliance and identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring equivalent environmental and regulatory standing.

Functional Compatibility: Both sensors employ identical Wheatstone Bridge output architecture with PC Pin termination and Through Hole mounting, enabling direct integration into existing board designs without circuit topology modification.

Electrical Operating Envelope: The TSCSAAN001PDUCV supply voltage range (1.5V ~ 12V) overlaps with the CPC0.3DFH range (3V ~ 16V) within the 3V to 12V common operational window, supporting existing power supply configurations.

Pressure Measurement Capability: The TSCSAAN001PDUCV operating pressure of ±1PSI (±6.89kPa) encompasses the CPC0.3DFH nominal range of 0.3PSI (2.07kPa). The substitute's maximum pressure rating of ±12.5PSI (±86.18kPa) provides enhanced overpressure protection compared to the original 5PSI maximum.

Performance Enhancement: The TSCSAAN001PDUCV delivers improved accuracy (±0.2% vs. ±2%) and extended low-temperature operation (-40°C vs. -25°C minimum), representing specification advancement without functional compromise.

Mechanical Interface Considerations: Port size differs between parts (0.16" vs. 0.19" tube diameter). Tubing adapter fittings are required to accommodate the 0.03" (0.76mm) diameter increase. Both parts feature barbed male ports with dual port configuration, maintaining pneumatic interface compatibility with appropriate adapter selection.

Frequently Asked Questions (FAQ)

Q: Can the TSCSAAN001PDUCV directly replace the CPC0.3DFH without circuit modifications?

A: The TSCSAAN001PDUCV maintains identical output type (Wheatstone Bridge), termination style (PC Pin), and package configuration (4-SIP Through Hole), enabling direct PCB mounting without circuit topology changes. However, tubing adapter fittings are required due to port size difference (0.16" to 0.19" tube diameter).

Q: What is the impact of the different operating pressure ranges?

A: The CPC0.3DFH operates at 0.3PSI (2.07kPa) nominal, while the TSCSAAN001PDUCV operates at ±1PSI (±6.89kPa) nominal. The substitute's range encompasses the original specification. For applications requiring precise 0.3PSI measurement, the TSCSAAN001PDUCV's improved accuracy (±0.2% vs. ±2%) provides superior performance within the overlapping measurement envelope.

Q: Are there supply voltage compatibility issues?

A: The CPC0.3DFH operates at 3V ~ 16V supply, while the TSCSAAN001PDUCV operates at 1.5V ~ 12V supply. Both parts function within the 3V to 12V common range. Applications requiring supply voltages above 12V must be evaluated for compatibility with the substitute's maximum 12V specification.

Q: What output signal differences exist between these parts?

A: The CPC0.3DFH outputs 0 mV ~ 20 mV at 12V supply, while the TSCSAAN001PDUCV outputs 0 mV ~ 15 mV at 5V supply. Signal conditioning circuits must be adjusted to accommodate the different output voltage levels and supply requirements.

Q: How do the port configurations differ?

A: Both parts feature dual barbed male ports. The CPC0.3DFH uses 0.16" (4.06mm) tube diameter ports, while the TSCSAAN001PDUCV uses 0.19" (4.93mm) tube diameter ports. The TSCSAAN001PDUCV specifies opposite-side port placement. Tubing adapters are required for the diameter transition, and PCB layout must accommodate the different port positioning.

Q: What is the temperature operating range difference?

A: The CPC0.3DFH operates from -25°C to 85°C, while the TSCSAAN001PDUCV operates from -40°C to 85°C. The substitute provides extended low-temperature capability, beneficial for applications requiring operation below -25°C.

Q: Are both parts RoHS compliant?

A: Yes, both the CPC0.3DFH and TSCSAAN001PDUCV are RoHS Compliant with identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: What accuracy improvement does the substitute provide?

A: The CPC0.3DFH specifies ±2% accuracy, while the TSCSAAN001PDUCV specifies ±0.2% accuracy. This represents a 10-fold improvement in measurement precision, providing enhanced system performance for pressure monitoring applications.
