Parameter Comparison

Engineering Selection Recommendations

The 142PC05DW79 is designated as obsolete and should be replaced with active equivalent alternatives to ensure long-term supply chain continuity and component availability. Both substitute parts—142PC05D and 142PC05D97—are classified as active products and maintain complete parametric equivalence with the original specification.

Selection Basis:

Both substitute parts satisfy all electrical and mechanical requirements for direct replacement:

• Identical pressure sensing characteristics (5PSI differential, ±1.5% accuracy)
• Matching analog voltage output (1V ~ 6V)
• Equivalent supply voltage range (7V ~ 16V)
• Identical mechanical interface (Male 0.2" dual tube, barbless)
• Same termination and mounting configuration (PC Pin, Through Hole, 3-SIP Module)
• Full RoHS compliance and MSL rating equivalence

The selection between 142PC05D and 142PC05D97 is determined by application-specific requirements and supplier availability, as both parts are functionally and mechanically interchangeable with the 142PC05DW79.

Frequently Asked Questions (FAQ)

Q: Can the 142PC05D and 142PC05D97 be used interchangeably with the 142PC05DW79?

A: Yes. Both substitute parts maintain complete parametric equivalence across all electrical and mechanical specifications, including pressure range, output characteristics, supply voltage, port configuration, and package type. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the primary reason for substituting the 142PC05DW79?

A: The 142PC05DW79 is classified as obsolete. The active alternatives (142PC05D and 142PC05D97) provide equivalent functionality with assured long-term availability and supply chain support.

Q: Are there any differences in the output signal between the original and substitute parts?

A: No. All parts deliver identical analog voltage output (1V ~ 6V) with ±1.5% accuracy across the 5PSI operating pressure range and -40°C to 85°C temperature range.

Q: Do the substitute parts require different mounting or termination approaches?

A: No. The substitute parts use identical Through Hole mounting, PC Pin termination, and 3-SIP Module packaging. No PCB layout modifications are required.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both 142PC05D and 142PC05D97 are RoHS compliant with MSL rating of 1 (Unlimited), matching the original 142PC05DW79 specification.

Q: What is the pressure port configuration for these sensors?

A: All parts feature Male 0.2" (5mm) dual tube ports with barbless design, supporting direct connection to standard tubing without additional adapters.

Q: Can these sensors operate across the full -40°C to 85°C temperature range?

A: Yes. All parts are rated for operation across the complete -40°C to 85°C temperature range with temperature compensation integrated into the sensor design.
