SCC30D Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC30D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 30PSI (206.84kPa) differential pressure measurement. The sensor outputs a Wheatstone Bridge signal in the range of 60 mV to 150 mV and operates across a temperature range of -40°C to 85°C.

The SCC30D has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCC30D is based on the following critical parameters that must align between the original and substitute part:

Mandatory Matching Parameters:

• Pressure Type: Differential
• Operating Pressure Range: 30PSI (206.84kPa) nominal
• Maximum Pressure Rating: 60PSI (413.69kPa)
• Output Type: Wheatstone Bridge
• Package / Case: 4-SIP Module
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -40°C ~ 85°C

Allowable Variations:

• Output voltage range may differ while maintaining Wheatstone Bridge output topology
• Accuracy specification may improve (lower tolerance value)
• Supply voltage range may be specified in substitute parts
• Temperature compensation features may be added

The NSCSSNN030PDUNV meets all mandatory matching parameters and qualifies as a direct substitute for the SCC30D.

Engineering Selection Recommendations

The NSCSSNN030PDUNV is a qualified substitute for the obsolete SCC30D based on the following engineering criteria:

Product Status Alignment: The SCC30D is obsolete with no ongoing production. The NSCSSNN030PDUNV is an active product from the same manufacturer, ensuring long-term supply availability and continued technical support.

Compliance and Certification: Both parts maintain RoHS compliance and carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 9026.20.4000, ensuring regulatory consistency.

Functional Equivalence: The substitute maintains identical pressure type (differential), operating pressure (30PSI / 206.84kPa), maximum pressure rating (60PSI / 413.69kPa), output topology (Wheatstone Bridge), package configuration (4-SIP Module), mounting method (Through Hole), and operating temperature range (-40°C ~ 85°C).

Performance Enhancement: The NSCSSNN030PDUNV provides improved accuracy (±0.25% versus ±0.5%) and explicitly specifies a supply voltage range of 1.5V ~ 12V, offering greater design flexibility.

Circuit Modification Required: The output voltage range differs between parts (60 mV ~ 150 mV for SCC30D versus 0 mV ~ 207 mV for NSCSSNN030PDUNV). Signal conditioning and calibration adjustments in the receiving circuit are necessary to accommodate this voltage level change.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN030PDUNV be used as a direct pin-for-pin replacement for the SCC30D?

A: The NSCSSNN030PDUNV shares identical package configuration (4-SIP Module), mounting type (Through Hole), and termination style (PC Pin) with the SCC30D. However, the output voltage range differs, requiring signal conditioning circuit modifications. Physical installation is compatible; electrical integration requires recalibration.

Q: What is the primary difference in output specifications between these two sensors?

A: The SCC30D outputs 60 mV ~ 150 mV, while the NSCSSNN030PDUNV outputs 0 mV ~ 207 mV (5V). Both use Wheatstone Bridge output topology. The receiving circuit must be adjusted to accommodate the different voltage levels and scaling factors.

Q: Does the NSCSSNN030PDUNV require different supply voltage than the SCC30D?

A: The SCC30D does not specify a supply voltage range in the provided data. The NSCSSNN030PDUNV specifies 1.5V ~ 12V supply voltage. Verify the original SCC30D supply voltage requirements in your application documentation before substitution.

Q: Are both sensors suitable for the same temperature operating range?

A: Yes. Both the SCC30D and NSCSSNN030PDUNV operate across -40°C ~ 85°C, ensuring thermal compatibility in equivalent applications.

Q: What is the accuracy difference between these sensors?

A: The SCC30D provides ±0.5% accuracy, while the NSCSSNN030PDUNV provides ±0.25% accuracy. The substitute offers improved measurement precision.

Q: Are there any regulatory or compliance concerns with substitution?

A: Both parts are RoHS Compliant, carry identical MSL ratings (1 - Unlimited), and share the same ECCN (EAR99) and HTSUS classifications (9026.20.4000). No regulatory barriers exist for substitution.

Q: What pressure ranges do these sensors support?

A: Both sensors operate at 30PSI (206.84kPa) differential pressure with a maximum pressure rating of 60PSI (413.69kPa). The NSCSSNN030PDUNV specifies ±30PSI and ±60PSI, indicating bidirectional pressure measurement capability.
