RSS-2412 DC DC Converter 12V 1W Equivalent & Substitute Parts

Part Overview

The RSS-2412 is an isolated module DC DC converter manufactured by Recom Power, designed for single 12V output applications with 84mA maximum current capacity. The converter accepts input voltage ranging from 21.6V to 26.4V and delivers 1W of power with 1 kV isolation. The RSS-2412 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance in commercial ITE applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSS-2412 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 21.6V – 26.4V
• Output voltage: 12V
• Maximum output current: 84mA
• Power rating: 1W
• Isolation voltage: 1 kV

Mechanical Compatibility Requirements:

• Mounting type: Surface Mount
• Package configuration: 8-SMD Module, 5 Leads
• Physical dimensions compatible with PCB layout constraints

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• Moisture sensitivity level MSL 1

The R1S-2412 meets all electrical and mechanical parameters specified for the RSS-2412, with the exception of an extended operating temperature maximum of 100°C versus 85°C for the original part. The R1S-2412 maintains active product status and full regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The R1S-2412 is the direct active equivalent for the obsolete RSS-2412. Both parts are manufactured by Recom Power within the ECONOLINE series and share identical electrical specifications, isolation characteristics, and mounting requirements.

Selection Basis:

The R1S-2412 provides functional equivalence with the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended maximum operating temperature of 100°C provides additional thermal margin compared to the RSS-2412 specification of 85°C
• Identical electrical performance across all critical parameters: input voltage range, output voltage, current capacity, power rating, and isolation voltage
• Full compliance with ROHS3 and REACH regulatory requirements
• Surface mount package configuration and 8-SMD Module form factor remain unchanged, supporting direct PCB layout compatibility

For applications operating within the original RSS-2412 temperature specification of -40°C to 85°C, the R1S-2412 operates within its qualified range and provides direct substitution. For applications requiring operation above 85°C, the R1S-2412 extended temperature capability to 100°C offers enhanced performance margin.

Frequently Asked Questions (FAQ)

Q: Can the R1S-2412 directly replace the RSS-2412 in existing designs?

A: Yes. The R1S-2412 maintains identical electrical specifications, output voltage, current capacity, isolation voltage, and surface mount package configuration. PCB layout compatibility is preserved.

Q: What is the primary difference between the RSS-2412 and R1S-2412?

A: The R1S-2412 extends the maximum operating temperature from 85°C to 100°C and maintains active product status. All other electrical and mechanical parameters are identical.

Q: Are there any packaging differences between these parts?

A: Both parts use 8-SMD Module, 5 Leads surface mount packages. Physical dimensions differ slightly: RSS-2412 measures 0.50" L × 0.32" W × 0.29" H, while R1S-2412 measures 0.50" L × 0.42" W × 0.28" H. The width dimension is larger on the R1S-2412 by 0.10 inches (2.5mm). PCB layout verification is required to confirm fit within existing footprints.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the RSS-2412 and R1S-2412 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What input voltage range do these converters accept?

A: Both converters accept input voltage from 21.6V to 26.4V, making them suitable for 24V nominal bus applications with specified tolerance bands.

Q: Is the R1S-2412 available in the same packaging format as the RSS-2412?

A: Both parts use surface mount 8-SMD Module, 5 Leads packages. The R1S-2412 is supplied in Tube packaging, while the RSS-2412 original packaging format is not specified in the provided data.
