RTD-1509/P-R Equivalent & Substitute Parts

Part Overview

The RTD-1509/P-R is an isolated module DC-DC converter manufactured by Recom Power, part of the ECONOLINE RTD (2W) series. This component provides dual output voltages of +9V and -9V with a maximum output current of 111mA per rail, operating from a 13.5V to 16.5V input supply. The module is designed for commercial ITE (Information Technology Equipment) applications and features short-circuit protection (SCP) with 1 kV isolation.

The RTD-1509/P-R is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this model is no longer available through standard distribution channels.

The substitute exhibits improved efficiency (80% versus 78%) and an extended operating temperature range (-40°C to 100°C versus -40°C to 85°C), providing enhanced performance margins for demanding applications.

Physical and Mechanical Compatibility: Both components utilize identical surface mount packaging (10-SMD Module, 6 Leads) and are designed for direct PCB integration. Dimensional differences are minimal and do not affect standard PCB layout compatibility.

Packaging Availability: The RTD-1509/P-R is supplied in Tape & Reel format, while the R2D-1509/P-R is available in Cut Tape and Digi-Reel® formats. Selection between packaging options depends on assembly process requirements and order quantity specifications.

Frequently Asked Questions (FAQ)

Q: Can the R2D-1509/P-R replace the RTD-1509/P-R in existing designs?

A: Yes. The R2D-1509/P-R is electrically and mechanically equivalent to the RTD-1509/P-R across all critical parameters. Both components provide identical input voltage range (13.5V – 16.5V), dual output voltages (+9V and -9V), output current capacity (111mA per rail), power rating (2W), and isolation voltage (1 kV). Surface mount package compatibility is maintained.

Q: What are the key differences between these two parts?

A: The primary differences are product status and performance enhancements. The RTD-1509/P-R is obsolete, while the R2D-1509/P-R is active. The R2D-1509/P-R offers improved efficiency (80% versus 78%) and an extended operating temperature range (-40°C to 100°C versus -40°C to 85°C). Packaging format differs: Tape & Reel for the RTD-1509/P-R and Cut Tape/Digi-Reel® for the R2D-1509/P-R.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 export classification. Moisture sensitivity level is identical (MSL 1 – Unlimited) for both components.

Q: What packaging options are available for the substitute part?

A: The R2D-1509/P-R is supplied in Cut Tape (CT) and Digi-Reel® formats. Selection depends on assembly process requirements and order volume. The original RTD-1509/P-R was supplied in Tape & Reel (TR) format.

Q: Are there any thermal or performance considerations when substituting?

A: The R2D-1509/P-R provides enhanced thermal performance with an extended operating temperature range to 100°C (compared to 85°C for the RTD-1509/P-R) and improved efficiency at 80% (compared to 78%). These enhancements provide additional performance margin and are not limiting factors for substitution.

Q: Is the R2D-1509/P-R pin-compatible with the RTD-1509/P-R?

A: Yes. Both components use identical 10-SMD Module packaging with 6 leads, ensuring direct PCB footprint compatibility without layout modifications.
