Key Parameters

Substitute Part Grouping Explanation

Substitution of the ST100PG2SPGF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Operating pressure range: 0-100 PSI
• Output signal type: 4-20 mA analog current
• Accuracy specification: ±1%
• Port size and style: Male 1/4" NPT threaded connection
• Pressure measurement type: Vented gauge configuration
• Core features: Amplified output with temperature compensation

Compatible Substitute Criteria: Substitute parts must maintain these specifications within the defined tolerances. Variations in supply voltage range, maximum pressure rating, operating temperature limits, or termination style are acceptable provided the primary measurement function and interface remain unchanged.

M3051-000005-100PG (TE Connectivity Measurement Specialties) - Primary Substitute

The M3051-000005-100PG is functionally equivalent to the ST100PG2SPGF for applications requiring 0-100 PSI pressure measurement with 4-20 mA output. This substitute maintains all critical measurement parameters and interface specifications.

Compliance Considerations:

• The M3051-000005-100PG holds active product status, ensuring ongoing availability and manufacturer support
• Both sensors are RoHS compliant (ST100PG2SPGF: RoHS Compliant; M3051-000005-100PG: ROHS3 Compliant)
• Both are classified under ECCN EAR99 and HTSUS 9026.20.4000
• The TE Connectivity part is REACH Affected, requiring verification against specific application regulatory requirements

Parameter Deviations:

• Supply voltage range: M3051-000005-100PG operates 9V-30V versus ST100PG2SPGF 9.5V-35V. Verify system supply voltage falls within 9V-30V overlap range
• Maximum pressure rating: M3051-000005-100PG rated 200 PSI versus ST100PG2SPGF 300 PSI. Acceptable for applications not exceeding 200 PSI transient conditions
• Operating temperature: M3051-000005-100PG range -20°C to 85°C versus ST100PG2SPGF -40°C to 100°C. Verify application temperature environment remains within -20°C to 85°C limits
• Termination: M3051-000005-100PG supplied with cable termination; ST100PG2SPGF termination style not specified. Confirm connector compatibility with system wiring

Frequently Asked Questions (FAQ)

Q: Can the M3051-000005-100PG directly replace the ST100PG2SPGF in existing installations?

A: Direct replacement is possible when system operating conditions remain within the M3051-000005-100PG specifications. Verify that supply voltage operates within 9V-30V range, maximum pressure does not exceed 200 PSI, and operating temperature stays between -20°C and 85°C. Confirm cable termination compatibility with existing connectors.

Q: What are the critical parameters that must match for substitution?

A: Operating pressure range (0-100 PSI), output signal type (4-20 mA), accuracy (±1%), port configuration (1/4" NPT male threaded), and pressure measurement type (vented gauge) must remain identical. These parameters define the sensor's functional role in the measurement system.

Q: Are there differences in supply voltage requirements between these sensors?

A: Yes. The ST100PG2SPGF accepts 9.5V-35V while the M3051-000005-100PG accepts 9V-30V. Both sensors operate within the 9V-30V overlap range. If your system supplies voltage above 30V or below 9.5V, the M3051-000005-100PG may not be suitable.

Q: How do the maximum pressure ratings differ?

A: The ST100PG2SPGF is rated for 300 PSI maximum pressure, while the M3051-000005-100PG is rated for 200 PSI. Both measure 0-100 PSI in normal operation. The M3051-000005-100PG is suitable for applications where transient pressures do not exceed 200 PSI.

Q: What is the significance of the operating temperature range difference?

A: The ST100PG2SPGF operates from -40°C to 100°C, while the M3051-000005-100PG operates from -20°C to 85°C. Substitution is valid only when the application environment remains within -20°C to 85°C. Applications requiring operation below -20°C or above 85°C require the original ST100PG2SPGF or alternative sensors with extended temperature ranges.

Q: What packaging differences exist between these sensors?

A: The ST100PG2SPGF uses a cylinder metal package, while the M3051-000005-100PG uses a cylinder threaded package with cable termination. Verify that the cable termination and connector type of the M3051-000005-100PG are compatible with your system's wiring and connection requirements.

Q: Are both sensors RoHS compliant?

A: Yes. The ST100PG2SPGF is RoHS Compliant, and the M3051-000005-100PG is ROHS3 Compliant. Both meet RoHS requirements. The M3051-000005-100PG is also REACH Affected; verify compliance with your specific regulatory requirements.

Q: Why is the ST100PG2SPGF classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The M3051-000005-100PG maintains active product status, ensuring continued availability, technical support, and supply chain reliability for new designs and system maintenance.
