RTD-1212 Equivalent & Substitute Parts Reference

Part Overview

The RTD-1212 is an isolated module DC-DC converter manufactured by Recom Power, designed to deliver dual output voltages of +12V and -12V from a 10.8V to 13.2V input source. This 2W converter is rated for 83mA output on each rail and features 1kV isolation, making it suitable for commercial ITE applications requiring galvanic isolation.

The RTD-1212 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for existing applications and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RTD-1212 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 10.8V to 13.2V (exact match required)
• Output voltage configuration: +12V and -12V dual output (exact match required)
• Output current capability: 83mA per rail minimum (exact match required)
• Power rating: 2W (exact match required)
• Isolation voltage: 1 kV (exact match required)

Mechanical & Physical Requirements:

• Mounting type: Surface Mount (exact match required)
• Package type: 10-SMD Module, 6 Leads (exact match required)
• Form factor compatibility: Physical dimensions must accommodate existing PCB layouts

Compliance & Regulatory Requirements:

• RoHS3 compliance (mandatory for new designs)
• REACH unaffected status (mandatory for supply chain continuity)

The R2D-1212 meets all electrical and mechanical compatibility criteria with the RTD-1212. Both parts share identical input/output specifications, isolation ratings, and package configurations. The primary distinction is product status: the RTD-1212 is obsolete, while the R2D-1212 maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The R2D-1212 is the appropriate selection for new product development. This part maintains active production status with Recom Power, ensuring long-term availability and supply chain stability. The R2D-1212 provides an extended operating temperature maximum of 100°C compared to the RTD-1212's 85°C rating, offering improved thermal margin for demanding applications. Both parts carry identical RoHS3 and REACH compliance certifications, meeting current regulatory requirements.

For Existing RTD-1212 Applications: Direct substitution of the R2D-1212 for the RTD-1212 is electrically and mechanically valid. All critical electrical parameters—input voltage range, dual output voltages, output current ratings, power rating, and isolation voltage—are identical. The package configuration and mounting type are equivalent. The extended temperature range of the R2D-1212 provides additional operational margin without introducing compatibility concerns.

Supply Chain Considerations: The RTD-1212 obsolete status necessitates transition planning. Current inventory of 892 units provides limited supply for ongoing support. The R2D-1212, with 1151 units in stock and active production status, represents the sustainable long-term solution for this application category.

Frequently Asked Questions (FAQ)

Q: Can the R2D-1212 directly replace the RTD-1212 in existing circuit designs?

A: Yes. The R2D-1212 provides electrical and mechanical equivalence to the RTD-1212. Input voltage range, dual output voltages (+12V/-12V), output current ratings (83mA per rail), power rating (2W), isolation voltage (1 kV), and package configuration (10-SMD Module, 6 Leads) are identical. No circuit modifications are required.

Q: What is the significance of the extended operating temperature range in the R2D-1212?

A: The R2D-1212 operates to 100°C maximum, compared to the RTD-1212's 85°C maximum. This 15°C extension provides additional thermal margin in applications approaching the RTD-1212's temperature limits. For applications operating within the RTD-1212's original -40°C to 85°C range, this difference does not affect performance.

Q: Are there physical dimension differences between the RTD-1212 and R2D-1212?

A: Both parts use the 10-SMD Module, 6 Leads package. The R2D-1212 width is 10.7mm compared to the RTD-1212's 9.3mm. Length (15.2mm) and height (9.0mm) are identical. PCB layout verification is recommended to confirm clearance in space-constrained applications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both the RTD-1212 and R2D-1212 are ROHS3 compliant and REACH unaffected. They meet current regulatory requirements for commercial ITE applications.

Q: Why is the RTD-1212 listed as obsolete?

A: Product obsolescence reflects Recom Power's manufacturing and support decisions. The R2D-1212 represents the active production equivalent within the ECONOLINE series, ensuring continued availability and technical support.

Q: What packaging differences exist between the two parts?

A: The RTD-1212 is supplied in standard packaging, while the R2D-1212 is supplied in Tube packaging. Both contain identical components and specifications. Tube packaging is standard for active production parts and does not affect electrical or mechanical performance.
