Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24PCDFC6G is determined by strict alignment of the following critical parameters:

Pressure Specifications: Operating pressure range must match ±30PSI (±206.84kPa) compound measurement capability.

Output Characteristics: Wheatstone Bridge output type is required. Output voltage range compatibility must be evaluated based on system signal conditioning design.

Electrical Interface: Supply voltage range, output impedance, and signal levels must be compatible with existing circuit design.

Mechanical Interface: Port size (0.18" tube), port style (barbless vs. barbed), and termination style (PC Pin) determine physical compatibility.

Environmental Compliance: Operating temperature range (-40°C to 85°C) and RoHS compliance status must be maintained.

Package Configuration: 4-SIP Module through-hole mounting is the standard form factor for this product category.

The 26PCDFB6G qualifies as a substitute based on matching pressure range, output type, port size tolerance, temperature range, mounting type, package configuration, and RoHS compliance.

Engineering Selection Recommendations

Active Product Status: The 26PCDFB6G is classified as active, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards. The 24PCDFC6G is obsolete, limiting future procurement options.

Compliance Certification: Both parts maintain RoHS compliance and identical MSL ratings, supporting equivalent environmental and reliability requirements.

Output Signal Differences: The 26PCDFB6G produces 0 mV ~ 100 mV output versus the 24PCDFC6G's 0 mV ~ 330 mV output. This represents a 3.3:1 reduction in signal amplitude. System signal conditioning and analog-to-digital conversion must accommodate this lower output range. The 26PCDFB6G's improved accuracy specification (±0.2% versus ±1%) provides enhanced measurement precision.

Supply Voltage Flexibility: The 26PCDFB6G accepts 2.5V ~ 16V supply voltage, compared to the 24PCDFC6G's 10V ~ 12V range. This broader input tolerance provides design flexibility for multi-voltage system architectures.

Mechanical Interface Considerations: Port size tolerance is equivalent (4.6mm versus 4.57mm). The 26PCDFB6G features barbed port style versus the 24PCDFC6G's barbless design. Barbed connections provide enhanced tubing retention in high-vibration environments.

Temperature Compensation: The 26PCDFB6G includes temperature compensation, reducing thermal drift effects across the -40°C to 85°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 26PCDFB6G directly replace the 24PCDFC6G without circuit modifications?

A: Direct replacement requires evaluation of signal conditioning circuits. The 26PCDFB6G's 100 mV maximum output versus the 24PCDFC6G's 330 mV output necessitates amplifier gain adjustment or analog-to-digital converter input scaling. Port style differences (barbed versus barbless) may require tubing connector evaluation.

Q: What is the significance of the output voltage difference between these sensors?

A: The 24PCDFC6G produces 33 mV per PSI (330 mV / 10 PSI span), while the 26PCDFB6G produces 10 mV per PSI (100 mV / 10 PSI span). Signal processing electronics must be recalibrated accordingly. The lower output of the 26PCDFB6G may require lower-noise amplification stages.

Q: Are the port connections compatible?

A: Both sensors feature 0.18" male tube connections with nominal 4.6mm diameter. The 26PCDFB6G's barbed design provides mechanical retention advantages over the 24PCDFC6G's barbless configuration. Existing tubing connections may require evaluation for barbed compatibility.

Q: Does the 26PCDFB6G's temperature compensation affect substitution suitability?

A: Temperature compensation in the 26PCDFB6G reduces output drift across temperature extremes, improving system accuracy. This represents a functional enhancement rather than a compatibility limitation.

Q: What supply voltage should be used with the 26PCDFB6G?

A: The 26PCDFB6G operates across 2.5V ~ 16V. For direct substitution in systems designed for the 24PCDFC6G's 10V ~ 12V range, operation within this narrower band is acceptable and maintains compatibility with existing power supplies.

Q: Is the 4-SIP Module package identical between both sensors?

A: Both sensors use 4-SIP Module through-hole packaging with PC Pin termination, ensuring identical printed circuit board footprint compatibility.
