Honeywell 9253525 Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The Honeywell 9253525 is a sealed gauge pressure sensor from the Eclipse series designed for industrial pressure measurement applications. This component features a 100 PSI operating range with 4 mA to 20 mA analog current output, male 1/8" NPT threaded port connection, and amplified, temperature-compensated output. The product is classified as obsolete, making identification of functionally equivalent substitute components essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Honeywell 9253525 pressure sensor is determined by strict alignment of the following critical parameters:

Pressure Measurement Compatibility:

• Pressure type must be sealed gauge
• Operating pressure range must be 100 PSI (689.48 kPa)
• Maximum pressure rating must support 200 PSI (1378.95 kPa) or higher

Electrical Interface Compatibility:

• Output must be analog (current or voltage)
• Port connection must be male 1/8" (3.18 mm) NPT threaded
• Operating temperature range must encompass -40°C to 105°C

Performance & Compliance:

• Accuracy specification must be ±0.5% or better
• Temperature compensation must be present
• Amplified output must be present
• RoHS compliance required
• ECCN classification EAR99

The Amphenol SSI Technologies P51-100-S-G-P-4.5V-000-000 meets these substitution criteria with the exception of output signal type (voltage vs. current) and supply voltage specification, which requires circuit-level evaluation during integration.

Parameter Comparison

Engineering Selection Recommendations

Honeywell 9253525 Status: The Honeywell 9253525 is classified as obsolete. Current inventory availability is 817 pieces in new original condition. For new system designs or long-term production commitments, reliance on obsolete components presents supply chain risk.

Amphenol P51-100-S-G-P-4.5V-000-000 Status: The Amphenol SSI Technologies P51-100-S-G-P-4.5V-000-000 is classified as active product status with 888 pieces available in new original condition. This component shares identical pressure measurement specifications, port configuration, and operating temperature range with the Honeywell 9253525.

Critical Differences Requiring Evaluation:

1. Output Signal Type: The Honeywell outputs 4 mA to 20 mA current; the Amphenol outputs 0.5 V to 4.5 V. Systems designed for current-loop input require signal conditioning or receiver modification to accept voltage output.

2. Supply Voltage: The Honeywell operates from 9.5 V to 35 V; the Amphenol requires 5 V. Power supply architecture must be evaluated for compatibility.

3. Accuracy: The Honeywell provides ±0.25% accuracy; the Amphenol provides ±0.5%. Applications with tight tolerance requirements must account for this specification difference.

Compliance & Certification: Both components are RoHS compliant, classified under ECCN EAR99, and share identical HTSUS commodity code 9026.20.4000, supporting equivalent regulatory and trade classification status.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol P51-100-S-G-P-4.5V-000-000 directly replace the Honeywell 9253525 without circuit modification?

A: No. The Amphenol outputs analog voltage (0.5 V to 4.5 V) while the Honeywell outputs analog current (4 mA to 20 mA). Systems designed for current-loop input require signal conditioning circuitry or receiver modification. Additionally, the Amphenol requires 5 V supply voltage versus the Honeywell's 9.5 V to 35 V range.

Q: Are the port connections identical between these two sensors?

A: Yes. Both sensors feature male 1/8" (3.18 mm) NPT threaded ports, enabling identical mechanical installation without adapter requirements.

Q: What is the accuracy difference between these two pressure sensors?

A: The Honeywell 9253525 provides ±0.25% accuracy while the Amphenol P51-100-S-G-P-4.5V-000-000 provides ±0.5% accuracy. For applications requiring measurement precision better than ±0.5%, the Honeywell specification is superior. Both accuracies are suitable for general industrial pressure monitoring.

Q: Do both sensors operate across the same temperature range?

A: Yes. Both sensors operate from -40°C to 105°C with temperature compensation, supporting identical environmental operating conditions.

Q: What is the significance of the obsolete status for the Honeywell 9253525?

A: Obsolete status indicates the manufacturer has discontinued production. While current inventory exists (817 pieces), future procurement may face availability constraints. The active status of the Amphenol component provides longer-term supply assurance for new designs or production continuity.

Q: Are both sensors RoHS compliant?

A: Yes. Both the Honeywell 9253525 and Amphenol P51-100-S-G-P-4.5V-000-000 are RoHS compliant and classified under identical ECCN (EAR99) and HTSUS (9026.20.4000) codes.

Q: What packaging differences exist between these sensors?

A: The Honeywell 9253525 is packaged with unspecified packaging designation. The Amphenol P51-100-S-G-P-4.5V-000-000 is supplied in box packaging with cylinder package/case configuration and 3-pin Packard termination style.
