DC030NDC4 Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DC030NDC4 is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 1.08PSI (7.48kPa) differential pressure range and analog voltage output of 0.25V to 4.25V. The sensor features a male barbed tube port (0.19" / 4.83mm) with dual connections and operates on a 5V supply. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DC030NDC4 are classified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Pressure Type: Differential
• Operating Pressure Range: ±1.08PSI (±7.48kPa) or equivalent
• Output Type: Analog Voltage
• Package Type: 4-SIP Module
• Mounting Type: Through Hole
• Port Configuration: Dual ports with male tube connection
• Accuracy: ±0.25%
• Temperature Compensation: Required

Direct Equivalent Classification: Parts meeting all primary criteria with identical or compatible electrical and mechanical specifications are classified as direct equivalents.

Similar Part Classification: Parts meeting core pressure and output specifications but with minor variations in port size, voltage output range, or supply voltage tolerance are classified as similar alternatives suitable for applications with flexible interface requirements.

Parameter Comparison

Engineering Selection Recommendations

SSCSNBN030NDAA5 (Honeywell TruStability® SSC Series)

This part is the primary direct equivalent for DC030NDC4 replacement. Both sensors share identical differential pressure specifications (±1.08PSI / ±7.48kPa), matching port size (0.19" / 4.8mm male tube), equivalent accuracy (±0.25%), and 4-SIP through-hole package configuration. The SSCSNBN030NDAA5 is an active product with extended supply voltage tolerance (4.75V ~ 5.25V versus 5V nominal) and expanded operating temperature range (-40°C ~ 85°C). Output voltage differs slightly (0.5V ~ 4.5V versus 0.25V ~ 4.25V), requiring verification of signal conditioning circuits in existing designs. The barbless port style eliminates mechanical retention features present in the original barbed design, necessitating alternative tubing attachment methods.

30 INCH-D-4V (Amphenol All Sensors ADCA Series)

This part provides functional equivalence with identical pressure range (±1.08PSI / ±7.48kPa), matching output voltage (0.25V ~ 4.25V), and compatible port size (0.19" / 4.8mm male tube). The 30 INCH-D-4V maintains the same 4-SIP through-hole package and ±0.25% accuracy specification. Supply voltage tolerance is broader (4.5V ~ 5.5V), and maximum pressure rating is significantly higher (±28.91PSI / ±199.34kPa). The barbless port style requires tubing attachment method adjustment. This part is manufactured by a different supplier, offering supply chain diversification for long-term availability.

SSCSHHN001PDAA5 (Honeywell TruStability® SSC Series)

This part is classified as a similar alternative with closely matched differential pressure specification (±1PSI / ±6.89kPa, approximately 7% lower than DC030NDC4). Port size differs (0.16" / 3.94mm versus 0.19" / 4.83mm), requiring tubing adapter evaluation. Output voltage (0.5V ~ 4.5V) and supply voltage (4.75V ~ 5.25V) differ from the original specification. This part is suitable only for applications where the slightly reduced pressure range and different port size are compatible with system requirements.

All substitute parts maintain RoHS compliance and are classified as active products with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can SSCSNBN030NDAA5 directly replace DC030NDC4 without circuit modifications?

A: The SSCSNBN030NDAA5 shares identical pressure specifications and package configuration but differs in output voltage range (0.5V ~ 4.5V versus 0.25V ~ 4.25V) and port style (barbless versus barbed). Signal conditioning circuits designed for the original 0.25V ~ 4.25V output range require evaluation. Tubing attachment methods must be adapted for the barbless port design.

Q: What is the primary difference between barbed and barbless port styles?

A: Barbed ports feature mechanical retention features that grip tubing during insertion, providing passive retention without additional fasteners. Barbless ports require alternative attachment methods such as hose clamps, compression fittings, or adhesive-based connections. Port style selection depends on the tubing material and system assembly requirements.

Q: Is the 30 INCH-D-4V suitable for applications requiring the exact 0.25V ~ 4.25V output range?

A: Yes. The 30 INCH-D-4V maintains the identical 0.25V ~ 4.25V output voltage range as the DC030NDC4, making it compatible with existing signal conditioning circuits. Port style (barbless) and supply voltage tolerance (4.5V ~ 5.5V) differ from the original specification and require system-level evaluation.

Q: Why does SSCSHHN001PDAA5 have a different port size?

A: The SSCSHHN001PDAA5 is designed for applications requiring a smaller port diameter (0.16" / 3.94mm versus 0.19" / 4.83mm). This part is classified as a similar alternative rather than a direct equivalent due to the port size variation. Use this part only when the reduced port size is compatible with system tubing and manifold specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (SSCSNBN030NDAA5, SSCSHHN001PDAA5, and 30 INCH-D-4V) are RoHS compliant. The DC030NDC4 is RoHS Compliant, while the Amphenol part is ROHS3 Compliant, both meeting current environmental regulations.

Q: What is the impact of extended operating temperature range on part selection?

A: The SSCSNBN030NDAA5 and SSCSHHN001PDAA5 offer extended low-temperature operation (-40°C versus -25°C), providing additional margin for applications in cold environments. The 30 INCH-D-4V maintains the original -25°C lower limit. Temperature range selection depends on the specific application environment and system thermal requirements.

Q: Can supply voltage tolerance differences affect system performance?

A: Yes. The DC030NDC4 specifies 5V nominal supply, while substitutes offer tolerance ranges (4.75V ~ 5.25V or 4.5V ~ 5.5V). Verify that existing power supply regulation meets the substitute part's voltage tolerance specification. Broader tolerance ranges provide additional design margin but do not guarantee improved performance if the original supply design operates outside the substitute's specified range.
