Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSCDRRN250MDAA5 is determined by strict equivalence across the following critical parameters:

Pressure Measurement Specification: Operating pressure of ±3.63PSI (±25kPa) with differential measurement type must be maintained.

Electrical Interface: Output voltage range of 0.5V ~ 4.5V with supply voltage of 4.75V ~ 5.25V must be identical.

Accuracy and Compensation: Accuracy of ±0.25% and temperature compensation across -40°C ~ 85°C operating range must be preserved.

Physical Interface: Port configuration must match: Male barbed ports of 0.08" (1.93mm) tube diameter, dual ports on same side.

Package and Mounting: 8-DIP (0.524", 13.30mm) through-hole package with PC pin termination style must be maintained.

Compliance: RoHS compliance and MSL rating of 1 must be retained.

The SSCDRRT250MDAA5 meets all these criteria and is identified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The SSCDRRT250MDAA5 is the appropriate substitute for the obsolete SSCDRRN250MDAA5. Both components are manufactured by Honeywell Sensing and Productivity Solutions and share identical electrical, mechanical, and performance specifications across all critical parameters.

The primary distinction between these parts is product status: the SSCDRRN250MDAA5 is obsolete, while the SSCDRRT250MDAA5 is active. This status difference reflects manufacturing lifecycle management and does not indicate any functional or performance divergence.

Both parts maintain RoHS compliance and MSL rating of 1, ensuring compatibility with modern manufacturing and assembly processes. The substitute part is available in higher inventory quantities (1109 pieces versus 774 pieces), supporting supply chain continuity.

For applications currently using the SSCDRRN250MDAA5, direct substitution with SSCDRRT250MDAA5 requires no circuit modifications, recalibration, or firmware adjustments. Pin configuration, electrical interface, and mechanical mounting are fully compatible.

Frequently Asked Questions (FAQ)

Q: Can SSCDRRT250MDAA5 be used as a direct replacement for SSCDRRN250MDAA5?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, pressure specifications, output characteristics, and physical dimensions match exactly. No circuit modifications are required.

Q: What is the difference between SSCDRRN250MDAA5 and SSCDRRT250MDAA5?
