Honeywell 24PCGFB2G Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The Honeywell 24PCGFB2G is a compound pressure sensor designed for board mount applications, featuring a ±250PSI operating range with Wheatstone Bridge output. This sensor operates within the 10V to 12V supply voltage range and delivers 0 mV to 212 mV output signals with ±1% accuracy. The device is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 24PCGFB2G is determined by strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure of ±250PSI (±1723.69kPa) and maximum pressure of ±500PSI (±3447.38kPa) must remain constant.

Electrical Characteristics: Output type (Wheatstone Bridge), output range (0 mV ~ 212 mV at 10V), accuracy (±1%), and supply voltage range (10V ~ 12V) must be identical.

Mechanical Interface: Port size (Male - 0.25" tube), mounting type (Through Hole), and package type (4-DIP Module) must match.

Environmental & Compliance: Operating temperature range (-40°C ~ 85°C), RoHS compliance, and MSL rating (1) must be maintained.

The 24PCGFA2G qualifies as a direct substitute based on these parameters. Minor variations in port style (barbless versus barbed) and packaging format (Bulk versus standard) do not affect functional equivalence when the core electrical and mechanical specifications remain aligned.

Engineering Selection Recommendations

The 24PCGFA2G is the designated substitute for the obsolete 24PCGFB2G. Both components maintain identical electrical performance specifications, pressure ratings, and environmental operating parameters. The 24PCGFA2G carries Active product status, ensuring continued availability and manufacturing support.

The primary distinction between these parts is port style configuration: the 24PCGFB2G features a barbed connection, while the 24PCGFA2G uses a barbless design. This variation affects tubing attachment methodology but does not alter sensor functionality or output characteristics. System designers must evaluate tubing connection requirements during integration planning.

Both components are RoHS Compliant with MSL rating of 1, confirming environmental and regulatory alignment. The 24PCGFA2G is available in Bulk packaging, supporting high-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 24PCGFA2G directly replace the 24PCGFB2G in existing applications?

A: The 24PCGFA2G provides electrical and mechanical equivalence for the obsolete 24PCGFB2G across all critical performance parameters. The primary consideration is port style: the barbless design of the 24PCGFA2G requires tubing connection methods compatible with non-barbed fittings. System integration must account for this mechanical variation.

Q: What is the significance of the port size difference (6.35mm versus 6.4mm)?

A: The nominal port sizes of 0.25" (6.35mm) and 0.25" (6.4mm) represent functionally equivalent tube connection points. This minor dimensional variation falls within standard tolerance ranges for 0.25-inch tubing interfaces and does not affect substitution compatibility.

Q: Are there differences in packaging that affect component selection?

A: The 24PCGFB2G is supplied in standard packaging, while the 24PCGFA2G is available in Bulk format. Bulk packaging is suitable for high-volume applications and does not alter component specifications or performance characteristics.

Q: How do the barbed and barbless port styles affect installation?

A: Barbed ports (24PCGFB2G) use mechanical barbs to retain tubing through friction and deformation. Barbless ports (24PCGFA2G) require alternative retention methods such as hose clamps or compression fittings. Installation procedures must be adapted accordingly based on the selected port style.

Q: Is the 24PCGFA2G suitable for applications requiring RoHS compliance?

A: Yes. The 24PCGFA2G is RoHS Compliant with MSL rating of 1 (Unlimited), matching the compliance profile of the 24PCGFB2G and supporting regulatory requirements for restricted substance management.

Q: What is the inventory status for these components?

A: The 24PCGFB2G (obsolete) has 1172 pieces in stock. The 24PCGFA2G (active) has 1081 pieces in stock. Active product status for the 24PCGFA2G ensures ongoing availability for future procurement cycles.
