SCC30A Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC30A is an absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 30PSI (206.84kPa) 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 product is classified as obsolete, making identification of functionally equivalent active alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCC30A is based on the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Pressure Type: Absolute
• Operating Pressure: 30PSI (206.84kPa)
• Maximum Pressure: 60PSI (413.69kPa)
• Output Type: Wheatstone Bridge
• Package / Case: 4-SIP Module
• Termination Style: PC Pin
• Port Style: No Port
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C ~ 85°C
• RoHS Compliance: Required

Allowable Parameter Variations:

• Output Range: May differ while maintaining Wheatstone Bridge output type
• Accuracy: May improve (lower tolerance value)
• Supply Voltage: May expand operating range
• Temperature Compensation: May be added as enhancement

The NSCSSNN030PAUNV meets all mandatory matching parameters and represents a direct functional equivalent with enhanced specifications.

Engineering Selection Recommendations

The NSCSSNN030PAUNV is the direct active equivalent for the obsolete SCC30A. Selection is based on the following engineering criteria:

Product Status Alignment: The SCC30A is obsolete. The NSCSSNN030PAUNV is active and currently manufactured, ensuring long-term availability and supply chain continuity.

Functional Equivalence: Both sensors maintain identical pressure measurement specifications (30PSI operating, 60PSI maximum), identical package form factor (4-SIP Module), and identical termination method (PC Pin through-hole). Both operate across the full -40°C to 85°C temperature range.

Compliance Certification: Both parts maintain RoHS compliance and identical export classification (EAR99), ensuring regulatory compatibility in existing applications.

Performance Enhancement: The NSCSSNN030PAUNV provides improved accuracy (±0.25% versus ±0.5%), representing a measurable enhancement in measurement precision. The specified supply voltage range (1.5V ~ 12V) provides design flexibility not documented in the SCC30A specification.

Output Characteristic Consideration: The output range differs (0 mV ~ 74 mV for NSCSSNN030PAUNV versus 60 mV ~ 150 mV for SCC30A). Both maintain Wheatstone Bridge output topology. Circuit redesign may be required to accommodate the different output voltage levels and supply voltage specifications.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN030PAUNV be used as a direct pin-for-pin replacement for the SCC30A?

A: Both sensors use 4-SIP Module packaging with PC Pin termination and identical through-hole mounting. Physical installation is compatible. However, the output voltage range differs (0 mV ~ 74 mV versus 60 mV ~ 150 mV), requiring signal conditioning circuit adjustment. The specified supply voltage range for NSCSSNN030PAUNV (1.5V ~ 12V) must be verified against the original SCC30A circuit design.

Q: What is the primary reason for substitution?

A: The SCC30A is classified as obsolete. The NSCSSNN030PAUNV is an active product from the same manufacturer with identical pressure measurement specifications, ensuring continued availability and manufacturing support.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain RoHS compliance, identical MSL rating (1 - Unlimited), identical ECCN classification (EAR99), and identical HTSUS code (9026.20.4000).

Q: How does accuracy differ between these sensors?

A: The NSCSSNN030PAUNV provides ±0.25% accuracy compared to the SCC30A's ±0.5% accuracy. This represents a 50% improvement in measurement tolerance.

Q: What pressure specifications must remain constant for substitution?

A: Operating pressure (30PSI / 206.84kPa), maximum pressure (60PSI / 413.69kPa), and pressure type (absolute) must remain identical. Both sensors meet these requirements.

Q: Is the operating temperature range identical?

A: Yes. Both sensors operate across -40°C to 85°C, ensuring thermal compatibility in existing applications.

Q: What design changes are necessary for circuit integration?

A: The primary circuit modification involves signal conditioning for the different output voltage range. The NSCSSNN030PAUNV outputs 0 mV ~ 74 mV (5V supply) compared to the SCC30A's 60 mV ~ 150 mV. Amplification and offset adjustment in the signal conditioning stage will be required. Supply voltage specifications must be verified and adjusted if necessary.
