Honeywell 9251707 Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The Honeywell 9251707 is a sealed gauge pressure sensor from the Eclipse series designed for industrial pressure measurement applications. This component features a 3000PSI operating pressure range with analog voltage output (0.5V to 4.5V) and is rated for -40°C to 105°C operation. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 9251707 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pressure Type: Sealed Gauge
• Operating Pressure: 3000PSI (20684.27kPa)
• Output Type: Analog Voltage
• Output Range: 0.5V to 4.5V
• Accuracy: ±0.25%
• Port Size: Male - 1/8" (3.18mm) NPT
• Port Style: Threaded
• Features: Amplified Output, Temperature Compensated

Allowable Parameter Variations:

• Supply Voltage: 5V to 6V (compatible with 5V base specification)
• Maximum Pressure: Equal to or greater than 4500PSI
• Operating Temperature Range: Equal to or exceeding -40°C to 105°C
• Termination Style: May differ if electrically compatible
• Product Status: Active status preferred for ongoing availability

The Honeywell MLH03KPSB06A meets all mandatory parameters and represents a direct functional equivalent with enhanced specifications in maximum pressure rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The Honeywell MLH03KPSB06A is a qualified substitute for the obsolete Honeywell 9251707 based on the following engineering criteria:

Functional Equivalence: All critical electrical and mechanical parameters match the original specification. The sensor maintains identical pressure measurement range (3000PSI), output characteristics (0.5V to 4.5V), accuracy (±0.25%), and port configuration (Male 1/8" NPT threaded).

Enhanced Specifications: The substitute part provides superior performance margins with a maximum pressure rating of 6000PSI versus 4500PSI, and an extended operating temperature range of -40°C to 125°C versus -40°C to 105°C. These enhancements provide additional design margin without compromising original application requirements.

Active Product Status: The MLH03KPSB06A is classified as active, ensuring ongoing availability, technical support, and supply chain continuity. This addresses the primary limitation of the obsolete 9251707.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, supporting regulatory and environmental requirements.

Connector Consideration: The substitute part features Packard Metripak 150 termination versus unspecified termination on the original. Connector compatibility must be verified against existing wiring harnesses and control system interfaces during integration.

Frequently Asked Questions (FAQ)

Q: Can the Honeywell MLH03KPSB06A directly replace the 9251707 in existing applications?

A: The MLH03KPSB06A provides electrical and mechanical compatibility for applications requiring 3000PSI sealed gauge pressure measurement with 0.5V to 4.5V analog output. The primary integration consideration is the Packard Metripak 150 connector termination, which must be verified against existing wiring interfaces. Mechanical mounting and port threading are identical.

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

A: The primary differences are product status (obsolete versus active), maximum pressure rating (4500PSI versus 6000PSI), operating temperature range (-40°C to 105°C versus -40°C to 125°C), and connector termination style. All core measurement specifications remain identical.

Q: Is the higher maximum pressure rating of the MLH03KPSB06A a concern for existing applications?

A: No. The higher maximum pressure rating (6000PSI) provides additional design margin and does not affect performance at the 3000PSI operating pressure. This enhancement improves component reliability and longevity in the application.

Q: Are there supply voltage compatibility issues?

A: The original 9251707 requires 5V supply. The MLH03KPSB06A accepts 5V to 6V supply voltage. Existing 5V power supplies are fully compatible. If 6V supply is available, the sensor will operate within specification.

Q: What is the significance of the Packard Metripak 150 connector on the substitute part?

A: The Packard Metripak 150 is a sealed automotive-grade connector. Integration requires verification that existing wiring harnesses and connector receptacles are compatible, or that adapter solutions are available. This is a mechanical integration consideration, not an electrical one.

Q: Are both parts RoHS compliant?

A: Yes. Both the Honeywell 9251707 and MLH03KPSB06A are RoHS compliant and carry identical MSL ratings of 1 (Unlimited), supporting regulatory and environmental requirements.

Q: Why is the 9251707 classified as obsolete?

A: The 9251707 is from the Eclipse series, which has been superseded by the active MLH series. The MLH03KPSB06A represents the current generation equivalent with enhanced specifications and ongoing manufacturer support.
