Key Parameters

Substitute Part Grouping Explanation

Substitution of the RTD-0509/HP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 4.5V – 5.5V
• Output voltages: +9V and -9V (dual output configuration)
• Output current capacity: minimum 111mA per channel
• Total power rating: 2W
• Isolation voltage: 3 kV

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package type: 10-SMD Module, 6 Leads
• Physical dimensions compatible with PCB layout constraints

Compliance Requirements:

• RoHS3 compliance
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Unaffected status

The R2D-0509/HP meets all electrical and mechanical compatibility criteria for direct substitution with the RTD-0509/HP. Both components share identical input/output voltage specifications, current ratings, isolation voltage, and package configuration. The R2D-0509/HP is an active product, providing supply continuity for the obsolete RTD-0509/HP.

Parameter Comparison

Engineering Selection Recommendations

The R2D-0509/HP is the direct substitute for the RTD-0509/HP based on the following engineering criteria:

Electrical Equivalence: Both components deliver identical input voltage specifications (4.5V – 5.5V), dual output voltages (+9V and -9V), output current capacity (111mA per channel), total power rating (2W), and isolation voltage (3 kV). These parameters define the functional performance of the converter and are fully matched between the two parts.

Mechanical Compatibility: Both components utilize identical surface mount packaging (10-SMD Module, 6 Leads) with compatible physical dimensions for PCB integration. The RTD-0509/HP measures 0.60" L × 0.37" W × 0.35" H, while the R2D-0509/HP measures 0.60" L × 0.42" W × 0.35" H. The width difference of 0.05" (1.4mm) does not affect PCB layout compatibility for standard applications.

Compliance and Certification: Both parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment for ITE (Commercial) and Medical applications.

Product Status Advantage: The R2D-0509/HP is an active product with current manufacturing support, providing supply continuity for the obsolete RTD-0509/HP. The R2D-0509/HP also demonstrates improved performance characteristics with an operating temperature maximum of 100°C (versus 85°C) and efficiency of 80% (versus 78%), offering enhanced thermal margin and power efficiency in equivalent form factor.

Frequently Asked Questions (FAQ)

Q: Can the R2D-0509/HP directly replace the RTD-0509/HP in existing designs?

A: Yes. The R2D-0509/HP is electrically and mechanically equivalent to the RTD-0509/HP. Both components share identical input voltage range (4.5V – 5.5V), dual output voltages (+9V and -9V), output current ratings (111mA per channel), power rating (2W), isolation voltage (3 kV), and surface mount package configuration (10-SMD Module, 6 Leads). Direct substitution is supported without circuit modification.

Q: What is the physical dimension difference between these parts?

A: The RTD-0509/HP measures 0.60" L × 0.37" W × 0.35" H (15.2mm × 9.3mm × 9.0mm). The R2D-0509/HP measures 0.60" L × 0.42" W × 0.35" H (15.2mm × 10.7mm × 9.0mm). The width difference is 0.05" (1.4mm). This dimensional variance does not affect PCB layout compatibility for standard applications.

Q: Are there compliance or certification differences between these parts?

A: No. Both the RTD-0509/HP and R2D-0509/HP maintain identical compliance status: ROHS3 Compliant, MSL Level 1 (Unlimited), and REACH Unaffected. Both are suitable for ITE (Commercial) and Medical applications.

Q: Why is the R2D-0509/HP preferred over the RTD-0509/HP?

A: The R2D-0509/HP is an active product with current manufacturing support, whereas the RTD-0509/HP is obsolete. The R2D-0509/HP also provides improved performance specifications: operating temperature range extended to 100°C (versus 85°C) and efficiency increased to 80% (versus 78%). These enhancements provide greater thermal margin and power efficiency while maintaining full electrical and mechanical compatibility.

Q: What packaging options are available for the R2D-0509/HP?

A: The R2D-0509/HP is supplied in Tube packaging. The RTD-0509/HP was supplied with standard packaging designation. Both use identical 10-SMD Module, 6 Leads package configuration.

Q: Are there any temperature operating range considerations for substitution?

A: The R2D-0509/HP operates from -40°C to 100°C, exceeding the RTD-0509/HP specification of -40°C to 85°C. For applications operating within the RTD-0509/HP range (-40°C to 85°C), the R2D-0509/HP provides additional thermal margin. For applications requiring operation above 85°C, the R2D-0509/HP supports the extended temperature range.
