Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSCMRRN100MD2A5 is determined by strict equivalence across the following critical parameters:

Pressure Specification: Operating pressure range must be ±1.45PSI (±10kPa) differential with maximum pressure rating of ±20.31PSI (±140kPa).

Electrical Interface: Output type must be I2C with 12-bit resolution to maintain firmware and circuit compatibility.

Electrical Supply: Supply voltage range must be 3V to 3.6V.

Accuracy: Measurement accuracy must be ±0.25%.

Mechanical Interface: Port configuration must be male barbed tubes of 0.08" (1.93mm) diameter, dual ports on the same side.

Package Configuration: Package must be 8-SMD with J-Lead termination style, suitable for surface mount assembly.

Environmental Specifications: Operating temperature range must span -40°C to 85°C.

Compliance: RoHS compliance status must be maintained.

The SSCMRRT100MD7A3 meets all these criteria and is classified as a parametric equivalent substitute.

Frequently Asked Questions (FAQ)

Q: Can the SSCMRRT100MD7A3 be used as a direct replacement for SSCMRRN100MD2A5 without circuit modifications?

A: Yes. The SSCMRRT100MD7A3 is a parametric equivalent with identical electrical specifications, I2C interface, 12-bit output, supply voltage range, and package configuration. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. The SSCMRRN100MD2A5 is obsolete, while the SSCMRRT100MD7A3 is active. All functional and electrical parameters are identical. The base product numbers differ (SSCMRRN versus SSCMRRT), indicating different manufacturing or packaging variants within the TruStability® SSC series.

Q: Are the mechanical port connections identical?

A: Yes. Both components feature male barbed tube ports of 0.08" (1.93mm) diameter, configured as dual ports on the same side. Tubing connections and pneumatic interface are fully compatible.

Q: Will the I2C communication protocol be the same?

A: Yes. Both components use I2C output with 12-bit resolution. Communication protocols, data formatting, and interface timing are identical.

Q: What is the packaging difference between these parts?

A: The SSCMRRN100MD2A5 is supplied in standard packaging, while the SSCMRRT100MD7A3 is supplied in bulk packaging. Both use 8-SMD, J-Lead surface mount packages suitable for automated assembly.

Q: Are there any temperature or pressure rating differences?

A: No. Both components have identical operating temperature range (-40°C to 85°C), operating pressure (±1.45PSI / ±10kPa), and maximum pressure rating (±20.31PSI / ±140kPa).

Q: Why should I choose the substitute part if the original is still in stock?

A: The SSCMRRT100MD7A3 is classified as active, ensuring long-term availability and continued manufacturer support. The SSCMRRN100MD2A5 is obsolete, meaning future stock may become unavailable. For production continuity and supply chain reliability, the active substitute is the recommended choice.
