Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC05DD4 is based on the following critical parameters that define functional equivalence:

Pressure Measurement Capability: Both the main part and substitute must support differential pressure measurement at ±5PSI (±34.47kPa) operating range with maximum pressure rating of ±20PSI (±137.9kPa).

Output Signal Type: Both components utilize Wheatstone Bridge output configuration, enabling direct signal compatibility in existing bridge measurement circuits.

Temperature Operating Range: Identical -40°C to 85°C operating temperature range ensures thermal performance equivalence across application environments.

Mounting and Termination: Both components feature through-hole mounting with PC pin termination, maintaining mechanical compatibility with existing PCB layouts.

Compliance Standards: Both parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory equivalence.

The NSCDRRN005PDUNV qualifies as a substitute despite differences in output voltage range, package configuration, and port size, as these parameters do not prevent functional substitution when system design accommodates the enhanced output specification and package footprint.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SCC05DD4 is classified as obsolete. The NSCDRRN005PDUNV is an active product from the same manufacturer, ensuring continued availability and manufacturing support for new production requirements or replacement inventory.

Compliance Equivalence: Both components maintain identical RoHS compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution in regulated applications.

Accuracy Enhancement: The NSCDRRN005PDUNV provides improved accuracy specification (±0.25% versus ±0.5%), offering superior measurement precision without compromising compatibility.

Output Signal Consideration: The substitute part provides expanded output range (0 mV ~ 150 mV at 5V supply) compared to the original (25 mV ~ 65 mV). System signal conditioning and analog-to-digital conversion circuits must accommodate this expanded range. The substitute requires external supply voltage (1.5V ~ 12V) whereas the original supply voltage specification is not provided.

Package and Port Differences: The NSCDRRN005PDUNV uses 8-DIP packaging versus 6-DIP, and features 0.08" (1.93mm) ports versus 0.09" (2.29mm). PCB layout modifications and tubing adapter compatibility must be evaluated for mechanical integration.

Frequently Asked Questions (FAQ)

Q: Can the NSCDRRN005PDUNV directly replace the SCC05DD4 without circuit modifications?

A: Direct pin-for-pin replacement is not possible due to package differences (6-DIP versus 8-DIP). However, functional substitution is achievable with circuit redesign to accommodate the expanded output voltage range and external supply voltage requirement. Port size differences (0.09" versus 0.08") require tubing adapter evaluation.

Q: What are the critical compatibility parameters for substitution?

A: Substitution is based on differential pressure measurement capability (±5PSI operating range), Wheatstone Bridge output configuration, identical operating temperature range (-40°C ~ 85°C), through-hole mounting with PC pin termination, and equivalent regulatory compliance (RoHS, REACH).

Q: How does the output signal difference affect system design?

A: The SCC05DD4 outputs 25 mV ~ 65 mV, while the NSCDRRN005PDUNV outputs 0 mV ~ 150 mV at 5V supply. Signal conditioning circuits, amplification stages, and analog-to-digital converter input ranges must be recalibrated to accommodate the substitute's expanded output specification.

Q: Are there supply voltage requirements for the substitute part?

A: The NSCDRRN005PDUNV requires external supply voltage between 1.5V and 12V. The original SCC05DD4 supply voltage specification is not provided in the component data. System power supply design must accommodate this requirement.

Q: What mechanical considerations apply to port size differences?

A: The SCC05DD4 features 0.09" (2.29mm) barbless ports, while the NSCDRRN005PDUNV features 0.08" (1.93mm) barbed ports. Tubing compatibility and connection method must be evaluated. Barbed ports provide mechanical retention, whereas barbless ports require alternative securing methods.

Q: Does the improved accuracy of the substitute part affect system performance?

A: The NSCDRRN005PDUNV provides ±0.25% accuracy versus the SCC05DD4's ±0.5%. This represents improved measurement precision and does not negatively affect system performance. Applications requiring higher accuracy benefit from this enhancement.
