BARO-A-4V-MIL Pressure Sensor Equivalent & Substitute Parts

Part Overview

The BARO-A-4V-MIL is an absolute pressure sensor manufactured by Amphenol All Sensors Corporation, designed for board mount applications requiring analog voltage output. This 4-SIP module sensor measures absolute pressure in the range of 8.7PSI to 15.95PSI (60kPa to 110kPa) with dual output channels providing 0.25V to 4.25V signals. The part is currently active in production with 652 pieces available in stock. Equivalent substitute parts are identified based on matching electrical specifications, mechanical interfaces, and environmental operating parameters to ensure direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BARO-A-4V-MIL are identified based on strict equivalence across the following critical parameters:

Pressure Specifications: Operating pressure range of 8.7PSI to 15.95PSI (60kPa to 110kPa) and absolute pressure type must match exactly.

Electrical Output: Analog voltage output with 0.25V to 4.25V range and supply voltage of 4.5V to 5.5V must be identical.

Mechanical Interface: Port size (Male - 0.19" / 4.83mm Tube, Dual), port style (Barbless), and package type (4-SIP Module) must be compatible.

Performance Characteristics: Accuracy (±2%), temperature compensation, amplified output, and operating temperature range (-40°C to 125°C) must be maintained.

Compliance & Certifications: RoHS Compliant status and Moisture Sensitivity Level 1 must be preserved.

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both BARO-A-4V-MIL and BARO-A-4V are active production parts from Amphenol All Sensors Corporation with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on availability and supply chain requirements. Both parts maintain RoHS Compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with standard PCB assembly processes and storage conditions. The BARO-A-4V offers higher inventory availability (769 pieces) compared to BARO-A-4V-MIL (652 pieces), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can BARO-A-4V be used as a direct replacement for BARO-A-4V-MIL?

A: Yes. Both parts are parametric equivalents with identical pressure range (8.7PSI to 15.95PSI), output voltage (0.25V to 4.25V), supply voltage (4.5V to 5.5V), accuracy (±2%), port configuration (Male - 0.19" Tube, Dual), package type (4-SIP Module), and operating temperature range (-40°C to 125°C). No circuit modifications are required for substitution.

Q: Are there any differences in mechanical interface between these parts?

A: No. Both parts feature identical port size (Male - 0.19" / 4.83mm Tube, Dual), port style (Barbless), termination style (PC Pin), and mounting type (Through Hole). Physical installation and PCB layout remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both BARO-A-4V-MIL and BARO-A-4V are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and ECCN EAR99 classification.

Q: What is the difference between BARO-A-4V-MIL and BARO-A-4V?

A: The parts are electrically and mechanically identical. The "-MIL" suffix typically indicates military-grade packaging or documentation, while BARO-A-4V represents the standard commercial variant. Both are active production parts with equivalent performance specifications.

Q: Which part should be selected for new designs?

A: Selection should be based on supply chain availability and procurement requirements. BARO-A-4V currently has higher inventory (769 pieces) compared to BARO-A-4V-MIL (652 pieces). Both parts are suitable for new board mount applications requiring absolute pressure measurement in the 8.7PSI to 15.95PSI range.
