ADP5251 Equivalent & Substitute Parts

Part Overview

The ADP5251 is a surface-mount pressure sensor manufactured by Panasonic Electronic Components, part of the PS-A series. This vented gauge pressure sensor operates at 29.01PSI (200kPa) with amplified Wheatstone Bridge output ranging from 0V to 4.5V. The component is actively produced and stocked at 1006 units, making it suitable for board-mount applications requiring pressure measurement with temperature compensation. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADP5251 is determined by strict equivalence across the following critical parameters:

• Operating Pressure: 29.01PSI (200kPa)
• Output Type: Wheatstone Bridge
• Output Voltage Range: 0V ~ 4.5V
• Supply Voltage: 5V
• Accuracy: ±1.5%
• Pressure Type: Vented Gauge
• Port Size: Male - 0.12" (3mm) Tube
• Port Style: Barbless
• Package / Case: 6-SMD Module
• Mounting Type: Surface Mount
• Operating Temperature: -10°C ~ 60°C
• Maximum Pressure: 58.02PSI (400kPa)

The ADP5250 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, mechanical interfaces, and environmental operating ranges, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the ADP5251 and ADP5250 are active products manufactured by Panasonic Electronic Components and maintain ROHS3 compliance. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences. The ADP5250 offers marginally higher inventory availability at 1020 units compared to 1006 units for the ADP5251. Both components carry identical electrical specifications, mechanical interfaces, and environmental ratings, ensuring functional interchangeability in all applications. No design modifications or circuit adjustments are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can the ADP5250 be used as a direct replacement for the ADP5251?

A: Yes. The ADP5250 is a parametric equivalent with identical operating pressure, output characteristics, supply voltage, accuracy, port configuration, package type, and temperature range. Direct substitution is supported without circuit modifications.

Q: Are there any differences in the 6-SMD Module package between these parts?

A: No. Both parts use the same 6-SMD Module package with identical termination style (Gull Wing) and surface-mount configuration, ensuring compatibility with existing PCB layouts and assembly processes.

Q: Do both parts support the same pressure range and output voltage?

A: Yes. Both the ADP5251 and ADP5250 operate at 29.01PSI (200kPa) nominal pressure with maximum pressure rating of 58.02PSI (400kPa), and both provide 0V to 4.5V output from a 5V supply with ±1.5% accuracy.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant and carry identical regulatory status (REACH Unaffected, ECCN EAR99, HTSUS 9026.20.4000).

Q: What is the barbless port configuration used for?

A: The barbless male 0.12" (3mm) tube port provides a smooth connection interface for pneumatic tubing without retention barbs, allowing for straightforward insertion and removal of tubing connections in pressure measurement applications.
