SCC05DN Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC05DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 5PSI (34.47kPa) differential pressure measurement. This sensor features a Wheatstone Bridge output with 25 mV ~ 65 mV signal range and operates across -40°C to 85°C. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SCC05DN is determined by the following critical parameters:

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

Output Interface: Both the main part and substitute utilize Wheatstone Bridge output topology, enabling direct signal compatibility with existing conditioning circuits.

Electrical Characteristics: The substitute must operate within the same temperature range (-40°C to 85°C) and maintain through-hole PC pin termination for PCB integration.

Mechanical Interface: Port configuration must accommodate dual barbed tube connections, though port size variation (0.19" to 0.16") is permissible if tubing adapters are employed.

Packaging and Mounting: Both components utilize 4-SIP module packaging with through-hole mounting, ensuring footprint compatibility on existing circuit boards.

Regulatory Compliance: RoHS compliance and REACH unaffected status are maintained across both components.

The NSCSHHN005PDUNV qualifies as a direct substitute based on these parameters, with the primary distinction being enhanced accuracy (±0.25% versus ±0.5%) and expanded output signal range (0 mV ~ 150 mV at 5V supply).

Engineering Selection Recommendations

Product Status Consideration: The SCC05DN is classified as obsolete, while the NSCSHHN005PDUNV maintains active production status. For applications requiring long-term component availability and supply chain continuity, the NSCSHHN005PDUNV is the appropriate selection.

Compliance and Certification: Both components maintain RoHS compliance and equivalent regulatory classifications (ECCN: EAR99, HTSUS: 9026.20.4000), ensuring no compliance barriers to substitution.

Signal Conditioning Requirements: The NSCSHHN005PDUNV operates with a specified supply voltage range (1.5V ~ 12V) and produces a wider output signal range (0 mV ~ 150 mV at 5V) compared to the SCC05DN (25 mV ~ 65 mV). Existing signal conditioning circuits must be evaluated and potentially recalibrated to accommodate this output difference.

Mechanical Interface Adaptation: The port size difference (0.19" versus 0.16" tube diameter) necessitates tubing adapter selection to maintain system integrity. Standard barbed tube adapters are commercially available for this transition.

Accuracy Enhancement: The NSCSHHN005PDUNV provides superior measurement accuracy (±0.25% versus ±0.5%), which may improve overall system performance in applications sensitive to pressure measurement precision.

Frequently Asked Questions (FAQ)

Q: Can the NSCSHHN005PDUNV be directly installed in place of the SCC05DN without modifications?

A: Direct pin-for-pin installation is possible due to identical 4-SIP through-hole PC pin termination and footprint compatibility. However, tubing adapter fittings are required to accommodate the 0.19" to 0.16" port size transition, and signal conditioning circuits must be recalibrated for the different output signal range.

Q: What is the primary reason for substituting the SCC05DN?

A: The SCC05DN is classified as obsolete, meaning Honeywell no longer manufactures this component. The NSCSHHN005PDUNV is an active product from the same manufacturer with equivalent pressure measurement specifications and superior accuracy, ensuring ongoing availability and supply chain reliability.

Q: Are there electrical compatibility concerns between these two sensors?

A: Both sensors employ Wheatstone Bridge output topology, which is electrically compatible. The key difference is the output signal range: the SCC05DN produces 25 mV ~ 65 mV, while the NSCSHHN005PDUNV produces 0 mV ~ 150 mV at 5V supply. Existing analog-to-digital conversion circuits or signal amplifiers must be recalibrated to accommodate this range difference.

Q: What supply voltage should be used with the NSCSHHN005PDUNV?

A: The NSCSHHN005PDUNV operates with a supply voltage range of 1.5V ~ 12V. The specific voltage selection depends on the application requirements and existing power distribution architecture. A 5V supply is typical for generating the full 0 mV ~ 150 mV output range.

Q: Is the port size difference a significant barrier to substitution?

A: The port size difference (0.19" versus 0.16" barbed tube connections) requires mechanical adaptation through standard tubing reducers or adapters. This is a routine mechanical consideration and does not prevent functional substitution. Adapter selection should ensure pressure rating compatibility with the sensor's 20PSI maximum pressure specification.

Q: Do both sensors operate across the same temperature range?

A: Yes, both the SCC05DN and NSCSHHN005PDUNV operate across -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What is the accuracy improvement provided by the substitute part?

A: The NSCSHHN005PDUNV provides ±0.25% accuracy compared to the SCC05DN's ±0.5% accuracy, representing a 50% improvement in measurement precision. This enhanced accuracy may be beneficial in applications requiring tighter pressure measurement tolerances.
