DC2R5BDC4 Equivalent & Substitute Parts

Part Overview

The DC2R5BDC4 is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement with analog voltage output. This component operates within a 0.04 PSI (0.25 kPa) differential pressure range and delivers output signals between 0.25 V and 4.25 V.

The DC2R5BDC4 is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain system functionality in applications where original inventory is depleted or long-term supply cannot be guaranteed. Substitute parts must maintain electrical compatibility, mechanical fit, and performance characteristics within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC2R5BDC4 is determined by the following critical parameters:

Pressure Measurement Characteristics: Operating pressure range of 0.04 PSI (0.25 kPa) differential, maximum pressure rating of approximately 3.6 PSI (25 kPa), and accuracy of ±0.25%.

Electrical Output Specifications: Analog voltage output between 0.25 V and 4.25 V, compatible with 5 V supply systems.

Mechanical Interface: Male barbed tube port configuration with 0.19" (4.83 mm) nominal diameter, dual port arrangement for differential measurement.

Package and Mounting: 4-SIP module format with through-hole PC pin termination for direct board mounting.

Environmental Compliance: RoHS compliance and operating temperature range of -25°C to 85°C.

The substitute part 1 INCH-D-4V manufactured by Amphenol All Sensors Corporation satisfies these critical parameters within acceptable engineering tolerances.

Engineering Selection Recommendations

The 1 INCH-D-4V from Amphenol All Sensors Corporation is a direct functional substitute for the obsolete DC2R5BDC4. Selection of this substitute is supported by the following engineering factors:

Product Availability: The 1 INCH-D-4V maintains active product status with confirmed inventory of 838 units, ensuring reliable supply compared to the obsolete DC2R5BDC4.

Electrical Compatibility: Both sensors deliver identical output voltage ranges (0.25 V ~ 4.25 V) and maintain ±0.25% accuracy. The 1 INCH-D-4V supply voltage range of 4.5 V ~ 5.5 V encompasses the 5 V requirement of the original design.

Pressure Measurement Equivalence: Operating pressure specifications are functionally identical at 0.04 PSI (0.25 kPa) differential, with maximum pressure ratings within 0.02 PSI of each other.

Mechanical Interface: Port configuration, tube diameter, and dual-port arrangement are equivalent. The barbless port style of the 1 INCH-D-4V provides functionally equivalent tubing connection capability.

Regulatory Compliance: Both components meet RoHS requirements. The 1 INCH-D-4V carries ROHS3 compliance and REACH unaffected status, meeting current environmental standards.

Package and Mounting: 4-SIP module format and through-hole PC pin termination are identical, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 1 INCH-D-4V directly replace the DC2R5BDC4 without circuit modifications?

A: Yes. Both sensors share identical output voltage ranges, accuracy specifications, and package formats. The supply voltage range of the 1 INCH-D-4V (4.5 V ~ 5.5 V) is compatible with 5 V supply systems. No circuit modifications are required.

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

A: Barbed ports feature mechanical barbs that grip tubing from the inside, while barbless ports rely on compression or friction fit. Both styles provide functional tubing connections. The barbless design of the 1 INCH-D-4V is suitable for applications using standard tubing connection methods.

Q: Are the pressure measurement ranges identical?

A: The operating pressure specifications are functionally equivalent. The DC2R5BDC4 specifies 0.04 PSI (0.25 kPa), while the 1 INCH-D-4V specifies ±0.04 PSI (±0.25 kPa). Maximum pressure ratings differ by 0.02 PSI (0.08 kPa), which is negligible for practical applications.

Q: What is the significance of the 1 INCH-D-4V being an active product?

A: Active product status indicates ongoing manufacturing and supply availability. This ensures long-term component sourcing reliability compared to the obsolete DC2R5BDC4, which has no guaranteed future availability.

Q: Are there any temperature operating differences?

A: No. Both sensors operate across the identical temperature range of -25°C to 85°C with temperature compensation features.

Q: What certifications apply to the substitute part?

A: The 1 INCH-D-4V carries ROHS3 compliance, REACH unaffected status, and EAR99 export classification, meeting current regulatory requirements for electronic components.
