RSS-0515 DC DC Converter 15V 1W Equivalent & Substitute Parts

Part Overview

The RSS-0515 is an isolated module DC DC converter manufactured by Recom Power, designed to convert 4.5V to 5.5V input voltage to a regulated 15V output at 66mA maximum current. This 1W converter is classified as obsolete, which necessitates identification of active equivalent parts for continued system support and new design implementations. The part operates across the commercial ITE (Information Technology Equipment) application space with 1 kV isolation and short-circuit protection features.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RSS-0515 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Input voltage range: 4.5V to 5.5V
• Output voltage: 15V
• Maximum output current: 66mA
• Power rating: 1W
• Isolation voltage: 1 kV
• Efficiency: 82%

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package configuration: 8-SMD Module, 5 Leads
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

Functional Equivalence Criteria:

• Type: Isolated Module
• Features: Short-Circuit Protection (SCP)
• Applications: ITE (Commercial)

The R1S-0515 meets all electrical and mechanical equivalence requirements while maintaining identical functional characteristics and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The R1S-0515 is the direct active equivalent for the obsolete RSS-0515. Both parts are manufactured by Recom Power within the ECONOLINE series and maintain identical electrical specifications, output characteristics, and regulatory compliance certifications.

Selection Basis:

The R1S-0515 provides full functional replacement capability with the following advantages:

• Active product status ensures continued availability and manufacturing support
• Extended maximum operating temperature range (100°C versus 85°C) provides additional thermal margin for demanding applications
• Identical electrical performance across all critical parameters: input voltage range, output voltage, current capacity, isolation voltage, and efficiency
• Equivalent mechanical form factor and surface mount package configuration
• Maintained ROHS3 compliance and unlimited moisture sensitivity rating
• Same short-circuit protection feature set for ITE commercial applications

No performance degradation or functional compromise occurs when substituting the R1S-0515 for the RSS-0515 in existing designs or new implementations.

Frequently Asked Questions (FAQ)

Q: Can the R1S-0515 directly replace the RSS-0515 in existing circuit boards?

A: Yes. The R1S-0515 is electrically and mechanically equivalent to the RSS-0515. Both parts feature identical 8-SMD Module, 5 Leads surface mount packages with matching pinout and footprint requirements. No circuit modifications are necessary.

Q: What is the primary difference between these two parts?

A: The RSS-0515 is obsolete while the R1S-0515 is an active product. The R1S-0515 also extends the maximum operating temperature from 85°C to 100°C, providing enhanced thermal performance for high-temperature environments.

Q: Are the electrical specifications identical?

A: Yes. Both parts deliver 15V output at 66mA maximum current from a 4.5V to 5.5V input with 1 kV isolation, 1W power rating, and 82% efficiency. All electrical parameters are equivalent.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RSS-0515 and R1S-0515 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited).

Q: What packaging formats are available for the R1S-0515?

A: The R1S-0515 is supplied in Tube packaging. The RSS-0515 was supplied with standard packaging. Both use the same 8-SMD Module, 5 Leads physical configuration.

Q: Is the R1S-0515 suitable for ITE commercial applications?

A: Yes. The R1S-0515 is specified for ITE (Information Technology Equipment) commercial applications with short-circuit protection features, identical to the RSS-0515.

Q: What is the physical size difference between these parts?

A: The R1S-0515 width is 10.7mm compared to the RSS-0515 at 8.2mm. Length is 12.8mm for both. Height is 7.0mm for the R1S-0515 versus 7.3mm for the RSS-0515. These minor dimensional variations do not affect PCB footprint compatibility for standard surface mount applications.
