RSS-1509/P Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RSS-1509/P is an isolated DC-DC converter module in the ECONOLINE RSS (1W) series. It delivers a regulated 9V output at up to 111mA from a 13.5V to 16.5V input range, with 1kV isolation and surface mount packaging. This product has an obsolete status, requiring identification of suitable replacements to maintain design continuity and ensure availability in future builds.

Key Parameters

Substitute Part Grouping Explanation

Suitable substitute parts for RSS-1509/P must meet the following explicit criteria: identical or overlapping input and output voltages, output current equal to or greater than 111mA, isolation voltage of 1kV, power rating of 1W, surface mount configuration with the same package type (8-SMD Module, 5 Leads), efficiency of 78%, compliance with ROHS3, and an equivalent or wider operating temperature range.

The substitute part listed matches all required key parameters, allowing use within the same application category without deviation from the explicit product specifications.

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for RSS-1509/P, use R1S-1509/P if inventory availability and product status (active) are required. Both parts are ROHS3 compliant, have the same MSL rating, and meet equivalent regulatory requirements. R1S-1509/P extends the operating temperature range, maintains compatible electrical specifications, and fits the same surface mount footprint. Substitute parts listed in this document comply with all current certification and environmental standards referenced in the original part data.

Frequently Asked Questions (FAQ)

Q1: What criteria determine a valid substitute for RSS-1509/P?
A1: Valid substitutes must match input voltage range, output voltage and current rating, isolation voltage, package type, mounting method, efficiency, operating temperature, and compliance/certification parameters.

Q2: Is the R1S-1509/P package compatible with RSS-1509/P in existing layouts?
A2: Both use an 8-SMD Module, 5 Leads configuration for surface mounting, supporting direct replacement where footprint alignment is required.

Q3: Does R1S-1509/P differ in regulatory or environmental compliance from RSS-1509/P?
A3: No; both are ROHS3 compliant, have MSL 1 (Unlimited), and are REACH Unaffected.

Q4: What is the product lifecycle status and why does it matter?
A4: RSS-1509/P is obsolete, and R1S-1509/P is active. Substituting with an active part ensures ongoing availability.

Q5: Are all electrical and thermal parameters identical?
A5: All explicit electrical specifications provided, including voltage, current, isolation, power, and efficiency, are matched. R1S-1509/P supports a wider operating temperature range.
