RTD-1509/P Equivalent & Substitute Parts Reference

Part Overview

The RTD-1509/P by Recom Power is an isolated DC-DC converter module that provides dual outputs of +9V and -9V at 111mA each, with a total power rating of 2W. It operates over an input voltage range of 13.5V to 16.5V and is designed for ITE (Commercial) applications. This device features surface mount packaging and includes short circuit protection (SCP). As the RTD-1509/P is now designated as "Obsolete," identifying suitable substitute parts is necessary to maintain continued design support and ensure system compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for RTD-1509/P is determined strictly by the following key parameters:

• Electrical specifications (input voltage range, output voltages and current, power, isolation voltage)
• Function (isolated module, number of outputs)
• Feature set (short circuit protection)
• Package/mechanical compatibility (mounting type, package/case, size)
• Application suitability (ITE commercial)
• Compliance (RoHS, REACH, MSL, ECCN)

Substitute selection in this context is based only on parts meeting these explicit requirements.

Parameter Comparison

Engineering Selection Recommendations

The RTD-1509/P is listed as obsolete, and its substitute R2D-1509/P is active. Both parts are ROHS3 compliant, REACH unaffected, and have the same moisture sensitivity level (MSL 1). Both have EAR99 ECCN classification. Substitute selection can be based on maintaining compliance and continuous availability.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to ensure a substitute part is compatible with RTD-1509/P?
A1: Key parameters include electrical input/output ratings, number of outputs, power rating, isolation voltage, mounting type, package dimensions, application suitability, and compliance certifications.

Q2: Are package differences significant for these DC-DC converters?
A2: Both RTD-1509/P and R2D-1509/P use a 10-SMD Module with 6 leads in surface mount configuration; however, the width dimension differs slightly (9.3mm vs. 10.7mm). Mechanical fit should be verified against the PCB design.

Q3: Does the substitute part R2D-1509/P provide the same isolation and protection features?
A3: Yes, both parts provide 1 kV isolation and short circuit protection (SCP).

Q4: Are there any differences in compliance status between RTD-1509/P and R2D-1509/P?
A4: Both are ROHS3 compliant, REACH unaffected, and share MSL 1 and EAR99 ECCN status.

Q5: Why is it necessary to consider a substitute for RTD-1509/P?
A5: The RTD-1509/P is obsolete, requiring selection of an alternative part with the same key parameters to ensure sourcing continuity and design compatibility.
