Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 9251405 is determined by strict alignment of the following critical parameters:

Pressure Measurement Specifications:

• Pressure type classification (Sealed Gauge)
• Operating pressure range (1000 PSI / 6894.76 kPa nominal)
• Maximum pressure rating (minimum 1500 PSI / 10342.14 kPa)

Electrical Interface Requirements:

• Output type (Analog Voltage)
• Output signal range (0.5 V ~ 4.5 V)
• Supply voltage compatibility (5 V nominal, with tolerance range)
• Accuracy specification (±0.25%)

Mechanical Interface Specifications:

• Port connection type (Male - 1/8" NPT threaded)
• Functional features (Amplified Output, Temperature Compensated)

Compliance & Regulatory:

• RoHS compliance status
• MSL rating (1 - Unlimited)

The MLH01KPSB06A meets all substitution criteria across these parameter categories while maintaining active product status and enhanced operational specifications.

Parameter Comparison

Engineering Selection Recommendations

The MLH01KPSB06A serves as a direct functional equivalent to the obsolete Honeywell 9251405 pressure sensor. Both components share identical pressure measurement specifications, electrical output characteristics, and mechanical interface requirements.

Compliance Alignment: Both parts maintain RoHS compliance and MSL rating 1 (Unlimited) status, ensuring regulatory consistency in applications subject to environmental and moisture sensitivity requirements.

Operational Advantages of Substitute: The MLH01KPSB06A provides enhanced specifications beyond the original part:

• Maximum pressure rating increased from 1500 PSI to 2000 PSI
• Operating temperature range extended from 105°C to 125°C
• Supply voltage tolerance expanded to 5 V ~ 6 V range
• Active product status ensures ongoing availability and support

Electrical Interface Compatibility: The 0.5 V ~ 4.5 V output range, ±0.25% accuracy, and 5 V supply voltage specification remain identical, enabling direct signal conditioning circuit compatibility without modification.

Mechanical Interface Compatibility: Male 1/8" NPT threaded port configuration is preserved, allowing direct installation in existing manifold and system designs without adapter requirements.

Frequently Asked Questions (FAQ)

Q: Can the MLH01KPSB06A directly replace the 9251405 in existing systems?

A: Yes. The substitute part maintains identical pressure type classification, operating pressure range, output signal characteristics, accuracy specification, and mechanical port configuration. No circuit modifications or mechanical adaptations are required for direct substitution.

Q: What is the significance of the supply voltage range difference (5 V versus 5 V ~ 6 V)?

A: The MLH01KPSB06A accepts a wider supply voltage range. Systems designed for 5 V operation remain fully compatible. The expanded tolerance provides additional flexibility for applications with variable power supply conditions.

Q: Does the higher maximum pressure rating (2000 PSI vs. 1500 PSI) affect system compatibility?

A: No. The higher maximum pressure rating of the substitute part indicates greater structural margin and does not affect normal operation at the 1000 PSI nominal operating pressure. This represents an enhancement for system robustness.

Q: Are there termination style differences between these parts?

A: Yes. The 9251405 uses standard termination, while the MLH01KPSB06A features Packard Metripak 150 termination. Connector compatibility must be verified during integration planning.

Q: What is the inventory status for each part?

A: The 9251405 (obsolete) has 993 pieces in stock. The MLH01KPSB06A (active) has 763 pieces in stock. Long-term availability is assured only for the active MLH01KPSB06A part.

Q: Are both parts RoHS compliant?

A: Yes. Both the 9251405 and MLH01KPSB06A maintain full RoHS compliance status, ensuring regulatory alignment for applications subject to environmental restrictions.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes. This simplifies supply chain management and manufacturing procedures.
