RTD-1224/H Equivalent & Substitute Parts

Part Overview

The RTD-1224/H is an isolated module DC-DC converter manufactured by Recom Power, part of the ECONOLINE RTD series. This 2-watt converter provides dual output voltages of +24V and -24V from a 10.8V to 13.2V input, with a maximum output current of 42mA per rail. The device is designed for surface mount applications in ITE (Commercial) and Medical environments with 3 kV isolation and short-circuit protection (SCP).

The RTD-1224/H is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production and field service requirements for systems utilizing this converter.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RTD-1224/H is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 10.8V to 13.2V
• Output voltage configuration: +24V and -24V dual output
• Output current capacity: 42mA per rail minimum
• Power rating: 2W
• Isolation voltage: 3 kV
• Short-circuit protection (SCP) feature

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package configuration: 10-SMD Module with 6 Leads
• Physical footprint compatibility

Environmental and Compliance Requirements:

• Operating temperature range: Minimum -40°C to 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The R2D-1224/H meets all electrical and mechanical compatibility criteria. While the R2D-1224/H exhibits a slightly larger width dimension (0.42" versus 0.37") and an extended operating temperature range (-40°C to 100°C), these differences represent improvements or non-restrictive variations that do not prevent substitution in applications designed for the RTD-1224/H.

Engineering Selection Recommendations

Primary Substitute: R2D-1224/H

The R2D-1224/H is the direct functional equivalent of the RTD-1224/H and is the recommended substitute for new designs and field replacements. Selection of the R2D-1224/H is supported by the following factors:

Product Status: The R2D-1224/H holds Active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. The RTD-1224/H is Obsolete, making the R2D-1224/H the appropriate long-term solution.

Electrical Equivalence: All critical electrical parameters are identical, including input voltage range (10.8V to 13.2V), dual output configuration (+24V / -24V), output current capacity (42mA per rail), power rating (2W), isolation voltage (3 kV), and short-circuit protection feature.

Mechanical Compatibility: Both devices utilize identical mounting type (Surface Mount), package configuration (10-SMD Module, 6 Leads), and share the same length and height dimensions. The width difference of 0.05" (1.4mm) on the R2D-1224/H does not restrict substitution in standard PCB layouts.

Compliance and Environmental: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL rating of 1 (Unlimited). The R2D-1224/H provides an extended operating temperature maximum of 100°C compared to 85°C on the RTD-1224/H, representing an operational advantage with no compatibility restrictions.

Packaging: The R2D-1224/H is supplied in Tube packaging, which is standard for production and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the R2D-1224/H be used as a direct replacement for the RTD-1224/H in existing designs?

A: Yes. The R2D-1224/H provides electrical and mechanical equivalence across all critical parameters. The input voltage range, dual output voltages (+24V / -24V), output current capacity (42mA per rail), power rating (2W), isolation voltage (3 kV), and short-circuit protection are identical. Both devices use Surface Mount packaging with 10-SMD Module, 6-Lead configuration. The R2D-1224/H width is 0.05" (1.4mm) wider, which does not restrict PCB layout compatibility in standard applications.

Q: What is the significance of the product status difference between RTD-1224/H (Obsolete) and R2D-1224/H (Active)?

A: Product status indicates manufacturer support and supply availability. The RTD-1224/H is Obsolete, meaning Recom Power no longer manufactures or actively supports this part. The R2D-1224/H is Active, ensuring continued production, technical support, and reliable supply chain access for both new designs and field service requirements.

Q: Are there any thermal performance differences between these parts?

A: Both parts specify 85% efficiency. The R2D-1224/H operates across a wider temperature range (-40°C to 100°C) compared to the RTD-1224/H (-40°C to 85°C). This extended range on the R2D-1224/H provides additional operational margin in high-temperature environments without reducing performance in standard operating conditions.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the RTD-1224/H and R2D-1224/H are ROHS3 Compliant, REACH Unaffected, and carry MSL rating 1 (Unlimited). Both are classified under ECCN EAR99 and HTSUS 8504.40.9580. Compliance status is equivalent for both Medical and ITE (Commercial) applications.

Q: What packaging formats are available for the R2D-1224/H?

A: The R2D-1224/H is supplied in Tube packaging, which is standard for production assembly and field service applications. This packaging format is suitable for both automated pick-and-place equipment and manual component handling.

Q: Are there any lead-time or inventory considerations when transitioning from RTD-1224/H to R2D-1224/H?

A: The R2D-1224/H is an Active product with established supply chain availability. The RTD-1224/H is Obsolete. For new production and field service, the R2D-1224/H should be specified to ensure reliable component sourcing and eliminate obsolescence risk.
