Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete RSS-0505-R is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 4.5V to 5.5V
• Output voltage: 5V
• Output current capacity: 200mA minimum
• Power rating: 1W
• Isolation voltage: 1 kV
• Efficiency: 78%

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount
• Package configuration: 8-SMD Module, 5 Leads
• Physical dimensions within acceptable tolerance
• Moisture sensitivity level: 1 (Unlimited)

Regulatory Compliance Criteria:

• RoHS3 compliance
• REACH unaffected status
• ECCN classification: EAR99

The R1S-0505-R qualifies as a direct substitute based on matching all electrical specifications, maintaining identical isolation voltage and efficiency ratings, and preserving the same package footprint and lead configuration. The substitute part operates across an extended temperature range and maintains active product status.

Parameter Comparison

Engineering Selection Recommendations

The R1S-0505-R represents a direct functional equivalent to the obsolete RSS-0505-R for all applications requiring isolated 5V/200mA DC DC conversion with 1 kV isolation. Selection of the R1S-0505-R is supported by the following engineering factors:

Product Status: The R1S-0505-R maintains active product status with current manufacturing and distribution support, eliminating supply chain risk associated with the obsolete RSS-0505-R.

Electrical Equivalence: All critical electrical parameters match exactly, including input voltage range, output voltage and current specifications, isolation voltage, and efficiency rating. The substitute part delivers identical performance in the target application.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements. ECCN classification remains EAR99 for both variants.

Thermal Performance: The R1S-0505-R extends the maximum operating temperature to 100°C compared to the 85°C limit of the RSS-0505-R, providing enhanced thermal margin in applications operating at elevated ambient temperatures.

Mechanical Compatibility: Package configuration, lead count, and mounting type remain identical, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the R1S-0505-R replace the RSS-0505-R in existing designs without PCB modification?

A: Yes. Both parts use identical 8-SMD Module, 5 Lead packages with Surface Mount configuration. Physical dimensions are compatible, and the footprint remains unchanged. No PCB redesign is required.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Input voltage range (4.5V to 5.5V), output voltage (5V), output current (200mA), power rating (1W), isolation voltage (1 kV), and efficiency (78%) are identical. Both parts deliver equivalent electrical performance.

Q: What is the primary difference between the RSS-0505-R and R1S-0505-R?

A: The primary differences are product status and operating temperature range. The RSS-0505-R is obsolete with a maximum operating temperature of 85°C. The R1S-0505-R is an active product with an extended maximum operating temperature of 100°C.

Q: Do both parts meet current RoHS and REACH requirements?

A: Yes. Both the RSS-0505-R and R1S-0505-R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any packaging differences between these parts?

A: The RSS-0505-R is supplied in standard packaging. The R1S-0505-R is available in Cut Tape (CT) and Digi-Reel packaging options, providing flexibility in procurement quantities and handling methods.

Q: Can the R1S-0505-R be used in applications with operating temperatures above 85°C?

A: Yes. The R1S-0505-R supports continuous operation up to 100°C, making it suitable for higher temperature environments where the RSS-0505-R (limited to 85°C) would not be appropriate.
