Key Parameters

Substitute Part Grouping Explanation

Substitution of the MF020-1-LC3 is determined by strict alignment of the following critical parameters:

Output Signal Compatibility: Both the main part and substitute must provide 4mA to 20mA output to ensure direct integration with existing signal conditioning and control circuits.

Sensor Type: Both must be oxygen sensors to maintain functional equivalence in measurement application.

Supply Voltage and Current: The substitute must operate within or be compatible with the 22.8V to 25.2V supply voltage and 500mA current specification to function within existing power delivery infrastructure.

Oxygen Measurement Range: The substitute must cover the 1 mbar to 250 mbar range or a range that encompasses the operational requirements of the original application.

Regulatory Compliance: The substitute must maintain RoHS compliance status to satisfy environmental and regulatory requirements equivalent to the original component.

Moisture Sensitivity Level: MSL 1 (Unlimited) classification ensures the substitute can be stored and handled under the same conditions as the original part.

The OXY-FLEX-1-H from SST Sensing Ltd. meets all these substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: OXY-FLEX-1-H from SST Sensing Ltd. is the designated equivalent for MF020-1-LC3 applications.

Regulatory Compliance: The OXY-FLEX-1-H maintains ROHS3 compliance, which supersedes the RoHS compliance of the original part, ensuring continued adherence to current environmental regulations. Both parts carry EAR99 export classification.

Product Status Advantage: The OXY-FLEX-1-H is classified as an active product with current manufacturing support and documented inventory availability (2700 pieces), whereas the MF020-1-LC3 is obsolete. This ensures long-term component availability and technical support for future procurement requirements.

Performance Characteristics: The substitute provides ±1% accuracy compared to the original ±2%, and extends the operating temperature range to +85°C, offering improved performance margins for applications operating near the upper temperature limit of the original specification.

Signal and Power Compatibility: Both parts operate on identical 4mA to 20mA output and 500mA supply current, enabling direct replacement without signal conditioning circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the OXY-FLEX-1-H directly replace the MF020-1-LC3 in existing installations?

A: Yes. Both sensors provide 4mA to 20mA output, operate at 500mA supply current, and accept 24V supply voltage (within the MF020-1-LC3 specification of 22.8V to 25.2V). No circuit modifications are required for signal or power compatibility.

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

A: The MF020-1-LC3 provides ±2% accuracy, while the OXY-FLEX-1-H provides ±1% accuracy. The substitute offers improved measurement precision.

Q: Does the OXY-FLEX-1-H operate within the same temperature range as the MF020-1-LC3?

A: The OXY-FLEX-1-H operates from -10°C to +85°C, which encompasses the original part's range of -10°C to +50°C. The substitute supports an extended upper temperature limit of +85°C.

Q: Are both sensors RoHS compliant?

A: Yes. The MF020-1-LC3 is RoHS Compliant, and the OXY-FLEX-1-H is ROHS3 Compliant. ROHS3 represents the current regulatory standard and is fully compatible with RoHS requirements.

Q: What is the packaging format for the OXY-FLEX-1-H?

A: The OXY-FLEX-1-H is supplied in Bulk packaging, compared to the original part's packaging designation. Confirm packaging requirements for your procurement process.

Q: Is the OXY-FLEX-1-H currently available?

A: Yes. The OXY-FLEX-1-H is classified as an active product with 2700 pieces documented as new original in stock.

Q: Do both sensors have the same moisture sensitivity level?

A: Yes. Both the MF020-1-LC3 and OXY-FLEX-1-H are classified as MSL 1 (Unlimited), allowing unlimited storage and handling without moisture control requirements.
