Parameter Comparison

Engineering Selection Recommendations

The R2D-2412 is the direct substitute for the RTD-2412 based on the following engineering criteria:

Product Status Consideration: The RTD-2412 is classified as obsolete, indicating discontinued manufacturing and limited availability. The R2D-2412 maintains active product status with confirmed inventory of 1122 pieces, ensuring supply chain continuity and long-term component availability.

Electrical Equivalence: All critical electrical parameters are identical between the two parts: input voltage range, output voltage levels, output current capacity, power rating, isolation voltage, and efficiency. These parameters determine functional compatibility in the application circuit.

Thermal Performance Enhancement: The R2D-2412 extends the maximum operating temperature from 85°C to 100°C, providing improved thermal margin for applications operating in elevated ambient conditions or with higher component density on the PCB.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. Moisture sensitivity level remains at 1 (Unlimited) for both variants.

Mechanical Compatibility: Package configuration, mounting type, and lead count are identical, enabling direct PCB layout compatibility without redesign requirements.

Frequently Asked Questions (FAQ)

Q: Can the R2D-2412 be used as a direct replacement for the RTD-2412 in existing designs?

A: Yes. The R2D-2412 is electrically and mechanically equivalent to the RTD-2412. All critical parameters including input voltage range, output voltages, output current capacity, power rating, isolation voltage, and package configuration are identical. Direct substitution is supported without circuit modification.

Q: What is the primary difference between the RTD-2412 and R2D-2412?

A: The primary differences are product status and operating temperature range. The RTD-2412 is obsolete with a maximum operating temperature of 85°C, while the R2D-2412 is actively manufactured with an extended maximum operating temperature of 100°C. The R2D-2412 also specifies tube packaging.

Q: Are there any dimensional differences between these parts?

A: Minor dimensional variation exists in the width specification. The RTD-2412 measures 0.37" W (9.3mm), while the R2D-2412 measures 0.42" W (10.7mm). Length and height remain identical at 0.60" L × 0.35" H (15.2mm × 9.0mm). PCB layout verification is recommended to confirm clearance compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RTD-2412 and R2D-2412 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level ratings of 1 (Unlimited). Regulatory compliance is equivalent between the two parts.

Q: What is the significance of the active product status for the R2D-2412?

A: Active product status indicates ongoing manufacturing and distribution by Recom Power. This ensures component availability for new production orders, spare parts procurement, and design revisions. The RTD-2412's obsolete status limits availability to existing inventory only.

Q: Are the output current ratings identical for both parts?

A: Yes. Both the RTD-2412 and R2D-2412 deliver 83mA maximum current on the +12V output and 83mA maximum current on the -12V output, providing identical load capacity for dual-rail applications.

Q: Can the extended temperature range of the R2D-2412 affect circuit performance?

A: The extended temperature range of the R2D-2412 (-40°C to 100°C versus -40°C to 85°C) represents improved thermal capability and does not negatively affect circuit performance. Applications operating within the RTD-2412's original temperature range will experience identical performance with the R2D-2412.
