Key Parameters

Substitute Part Grouping Explanation

The NSCSSNN015PDUNV is identified as a direct substitute for the SCC15D based on the following critical parameters:

Pressure Specifications: Both sensors operate at ±15PSI (±103.42kPa) differential pressure with identical maximum pressure ratings of ±30PSI (±206.84kPa).

Output Configuration: Both sensors utilize Wheatstone Bridge output topology, enabling direct signal compatibility in existing circuit designs.

Physical Form Factor: Both sensors are packaged in 4-SIP Module configuration with PC Pin termination and Through Hole mounting, ensuring mechanical and electrical compatibility with existing PCB layouts.

Operating Environment: Both sensors function across the identical temperature range of -40°C to 85°C, maintaining performance consistency across thermal conditions.

Regulatory Compliance: Both sensors are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and reliability standards.

The NSCSSNN015PDUNV represents an active product from the TruStability® NSC series, providing improved accuracy (±0.25% versus ±0.5%) and expanded supply voltage range (1.5V to 12V) compared to the obsolete SCC15D.

Parameter Comparison

Engineering Selection Recommendations

The NSCSSNN015PDUNV is the qualified substitute for the obsolete SCC15D based on the following engineering criteria:

Product Lifecycle Status: The SCC15D is classified as obsolete, creating supply chain risk for new production and field replacements. The NSCSSNN015PDUNV maintains active product status with documented inventory availability, ensuring long-term supply continuity.

Regulatory Compliance: Both parts maintain identical RoHS Compliance and EAR99 export classification status, eliminating compliance barriers to substitution.

Electrical Compatibility: Both sensors employ Wheatstone Bridge output topology with identical pressure operating ranges and temperature specifications. The NSCSSNN015PDUNV provides expanded supply voltage flexibility (1.5V to 12V) compared to the unspecified supply voltage of the SCC15D, accommodating broader circuit design requirements.

Physical Compatibility: Identical 4-SIP Module packaging, PC Pin termination, and Through Hole mounting ensure direct PCB layout compatibility without redesign requirements.

Performance Enhancement: The NSCSSNN015PDUNV delivers improved accuracy (±0.25% versus ±0.5%), providing superior measurement precision in applications requiring tighter tolerance control.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN015PDUNV directly replace the SCC15D without circuit modifications?

A: The NSCSSNN015PDUNV is mechanically and electrically compatible with the SCC15D. Both sensors use identical 4-SIP Module packaging with PC Pin termination and Wheatstone Bridge output topology. However, the output signal range differs (0 mV ~ 155 mV for NSCSSNN015PDUNV versus 40 mV ~ 95 mV for SCC15D). Signal conditioning circuits must be evaluated to confirm compatibility with the expanded output range of the substitute part.

Q: What are the key electrical differences between these two sensors?

A: The primary electrical differences are output signal range and supply voltage specification. The NSCSSNN015PDUNV provides a wider output range (0 mV ~ 155 mV at 5V supply) with improved accuracy (±0.25% versus ±0.5%). The NSCSSNN015PDUNV specifies a supply voltage range of 1.5V to 12V, whereas the SCC15D does not specify supply voltage parameters. Both sensors maintain identical pressure operating ranges (15PSI differential) and temperature specifications (-40°C to 85°C).

Q: Are the physical dimensions and pin configurations identical?

A: Both sensors are packaged in 4-SIP Module configuration with PC Pin termination and Through Hole mounting. This ensures identical PCB footprint compatibility and mounting requirements. No mechanical redesign is necessary for physical substitution.

Q: What is the significance of the ± symbol in the NSCSSNN015PDUNV pressure specification?

A: The ± notation indicates the NSCSSNN015PDUNV can measure differential pressure in both positive and negative directions (±15PSI), whereas the SCC15D specification indicates unidirectional measurement capability. This represents an expanded functional capability of the substitute part.

Q: Are both parts RoHS compliant?

A: Yes, both the SCC15D and NSCSSNN015PDUNV are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both parts maintain identical regulatory compliance status.

Q: Why is the SCC15D classified as obsolete?

A: The SCC15D is part of the legacy SCC series. Honeywell has transitioned to the active TruStability® NSC series, which includes the NSCSSNN015PDUNV. The NSCSSNN015PDUNV represents the current generation equivalent with improved performance specifications and active manufacturing status.
