Honeywell 26PCAFK2G Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The Honeywell 26PCAFK2G is a compound pressure sensor designed for board mount applications. This sensor measures pressure in the ±1PSI (±6.89kPa) range with a Wheatstone Bridge output configuration. The device operates across a wide supply voltage range of 2.5V to 16V and delivers a linear output of 0 mV to 16.7 mV at 10V supply.

The 26PCAFK2G is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity where this sensor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 26PCAFK2G is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Output Type: Wheatstone Bridge configuration
• Output Range: 0 mV ~ 16.7 mV (10V)
• Supply Voltage Range: 2.5V ~ 16V
• Accuracy: ±0.5%

Mechanical Compatibility:

• Pressure Type: Compound
• Operating Pressure: ±1PSI (±6.89kPa)
• Port Size: Male - 0.2" Tube
• Port Style: Barbless
• Mounting Type: Through Hole
• Package Type: 4-SIP Module
• Termination Style: PC Pin

Environmental Specifications:

• Operating Temperature: -40°C ~ 85°C
• Maximum Pressure: ±20PSI (±137.9kPa)
• Temperature Compensation: Required

Compliance Requirements:

• RoHS Compliant
• MSL Rating: 1 (Unlimited)

Substitute parts must match all parameters listed above. Packaging format differences (such as Tray versus standard packaging) do not affect functional substitution when electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell 26PCAFA6G is a direct functional equivalent to the 26PCAFK2G. Both sensors share identical electrical specifications, mechanical dimensions, and environmental operating parameters. The primary distinction is product status: the 26PCAFK2G is obsolete, while the 26PCAFA6G is active and currently in production.

The 26PCAFA6G is supplied in Tray packaging format, whereas the 26PCAFK2G uses standard packaging. This packaging difference does not affect electrical or mechanical compatibility. Both parts are RoHS Compliant with MSL Rating 1 (Unlimited), meeting identical compliance requirements.

For applications requiring the 26PCAFK2G specification, the 26PCAFA6G provides continued availability with no functional compromise. The active production status of the 26PCAFA6G ensures supply chain continuity and long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the 26PCAFA6G replace the 26PCAFK2G in existing designs?

A: Yes. The 26PCAFA6G is electrically and mechanically equivalent to the 26PCAFK2G. All critical parameters—pressure range, output type, supply voltage, operating temperature, and mechanical interface—are identical. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between the 26PCAFK2G and 26PCAFA6G?

A: The primary differences are product status and packaging format. The 26PCAFK2G is obsolete; the 26PCAFA6G is active production. The 26PCAFA6G is supplied in Tray packaging, while the 26PCAFK2G uses standard packaging. Functional specifications are identical.

Q: Are there any compatibility concerns with the port size difference (5.08mm vs 5mm)?

A: No. The port size specifications (0.2" / 5.08mm for the 26PCAFK2G and 0.2" / 5mm for the 26PCAFA6G) are equivalent within standard engineering tolerances for male barbless tube connections. Both parts use identical port style and mechanical interface.

Q: Does the Tray packaging of the 26PCAFA6G affect performance?

A: No. Packaging format does not affect sensor performance, electrical output, or mechanical function. Tray packaging is a distribution and handling format only. The sensor itself operates identically regardless of packaging type.

Q: Are both parts RoHS Compliant?

A: Yes. Both the 26PCAFK2G and 26PCAFA6G are RoHS Compliant with MSL Rating 1 (Unlimited), meeting identical environmental and regulatory requirements.

Q: What is the availability status of these parts?

A: The 26PCAFK2G is obsolete. The 26PCAFA6G is active production with current inventory availability. For new designs and ongoing production, the 26PCAFA6G is the recommended selection.

Q: Can I use the 26PCAFA6G in applications originally designed for the 26PCAFK2G?

A: Yes. The 26PCAFA6G meets all electrical, mechanical, and environmental specifications of the 26PCAFK2G. No application modifications are required for direct substitution.
