Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1J-2-AX16PA is determined by strict equivalence across the following critical parameters:

• Pressure Measurement Range: Operating pressure of 0.07 PSI (0.5 kPa) differential and maximum pressure of 1.02 PSI (7 kPa)
• Output Interface: Digital I2C protocol with 14-bit resolution
• Electrical Specifications: Supply voltage range 2.7V ~ 5.5V and ±0.25% accuracy
• Mechanical Interface: Dual male barbed ports at 0.08" (1.92 mm) tube diameter
• Package Configuration: 8-DIP (0.524", 13.30 mm) with dual ports on the same side, through-hole PC pin termination
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating
• Functional Features: Amplified output and temperature compensation

The P1J-5MB-AX16PA meets all substitution criteria as a parametric equivalent within the P1J series.

Parameter Comparison

Engineering Selection Recommendations

Both the P1J-2-AX16PA and P1J-5MB-AX16PA are Last Time Buy components within the P1J series. The P1J-5MB-AX16PA is the designated parametric equivalent and direct substitute for the P1J-2-AX16PA. Selection between these parts should be based on current inventory availability and supply chain requirements, as both components are electrically and mechanically identical.

Both components carry ROHS3 compliance and MSL Level 1 ratings, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can the P1J-5MB-AX16PA be used as a direct replacement for the P1J-2-AX16PA in existing designs?

A: Yes. The P1J-5MB-AX16PA is a parametric equivalent with identical electrical specifications, pressure measurement range, I2C output protocol, 14-bit resolution, supply voltage requirements, accuracy, package configuration, port dimensions, and termination style. No design modifications are required.

Q: Are there any differences in the mechanical interface between these two parts?

A: No. Both components feature identical dual male barbed ports at 0.08" (1.92 mm) tube diameter, 8-DIP package dimensions (0.524", 13.30 mm), and through-hole PC pin termination. PCB layouts and connector specifications remain unchanged.

Q: What is the significance of the Last Time Buy status for both parts?

A: Last Time Buy status indicates that both the P1J-2-AX16PA and P1J-5MB-AX16PA are discontinued products with no further production planned. Existing inventory represents the final available supply. Long-term applications should evaluate alternative pressure sensor solutions from current product lines.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. They operate across the identical temperature range of -20°C to 85°C and meet the same regulatory requirements.

Q: Is there a difference in supply voltage compatibility?

A: No. Both the P1J-2-AX16PA and P1J-5MB-AX16PA operate across the identical supply voltage range of 2.7V to 5.5V, ensuring compatibility with standard 3.3V and 5V logic systems.
