IE1205S DC DC Converter 5V 1W Equivalent & Substitute Parts

Part Overview

The IE1205S is an isolated module DC DC converter manufactured by XP Power, designed for commercial ITE applications. This 1W converter accepts input voltage between 10.8V and 13.2V and delivers a regulated 5V output at 200mA maximum current. The device features 1 kV isolation and operates across the temperature range of -40°C to 85°C. The part is currently active in production and ROHS3 compliant.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same functional category. Alternative sources provide identical or superior performance characteristics while maintaining the same input/output voltage specifications, isolation rating, and form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IE1205S are qualified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Requirements:

• Input voltage range: 10.8V to 13.2V (exact match required)
• Output voltage: 5V (exact match required)
• Maximum output current: 200mA (exact match required)
• Power rating: 1W (exact match required)
• Isolation voltage: 1 kV (exact match required)
• Operating temperature range: -40°C to 85°C (exact match required)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match required)
• Package type: 4-SIP Module (exact match required)

Compliance Requirements:

• RoHS3 compliance (required for equivalent substitution)
• Product status: Active (current production)

All substitute parts listed maintain identical electrical specifications and mechanical form factors. Variations in efficiency and physical dimensions within the 4-SIP module envelope do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the IE1205S and are qualified for direct substitution in applications requiring a 5V 1W isolated DC DC converter with 10.8V to 13.2V input.

CRE1S1205SC (Murata Power Solutions Inc.): This substitute maintains all critical electrical and mechanical specifications. The device is ROHS3 compliant and carries IEC 60950-1 certification. Efficiency is rated at 71%, which is lower than the primary part but remains within acceptable operational parameters for the specified application class.

RO-1205S (Recom Power): This substitute is part of the ECONOLINE RO series and provides equivalent performance with 80% efficiency, exceeding the primary part specification. The device includes short-circuit protection (SCP) as an additional feature. All electrical and mechanical parameters match the primary part exactly.

ROE-1205S (Recom Power): This substitute is part of the ECONOLINE ROE E-Series and delivers identical electrical specifications and mechanical compatibility. Efficiency is rated at 80%, matching the RO-1205S performance level. This variant is suitable for applications requiring the E-Series designation.

All substitute parts are currently in active production with confirmed inventory availability. Selection among these alternatives is based on supply chain requirements, preferred manufacturer relationships, or specific feature requirements such as short-circuit protection.

Frequently Asked Questions (FAQ)

Q: Can the CRE1S1205SC be used as a direct replacement for the IE1205S?

A: Yes. The CRE1S1205SC maintains identical input voltage range (10.8V to 13.2V), output voltage (5V), output current (200mA), power rating (1W), isolation voltage (1 kV), operating temperature range (-40°C to 85°C), and package type (4-SIP Through Hole module). ROHS3 compliance and active product status confirm equivalence.

Q: What is the difference between RO-1205S and ROE-1205S?

A: Both parts are manufactured by Recom Power and maintain identical electrical specifications and mechanical form factors. The RO-1205S is part of the ECONOLINE RO series, while the ROE-1205S is part of the ECONOLINE ROE E-Series. The RO-1205S includes short-circuit protection (SCP) as a documented feature. Both deliver 80% efficiency and are suitable for direct substitution.

Q: Are there physical dimension differences between these substitute parts?

A: The IE1205S measures 0.46" L x 0.24" W x 0.50" H (11.7mm x 6.0mm x 12.7mm). The CRE1S1205SC measures 0.45" L x 0.24" W x 0.39" H (11.5mm x 6.1mm x 10.0mm). The RO-1205S and ROE-1205S both measure 0.45" L x 0.24" W x 0.39" H (11.5mm x 6.0mm x 10.0mm). All parts are classified as 4-SIP modules and fit within standard through-hole PCB layouts designed for this package type.

Q: Which substitute part offers the best efficiency?

A: Both the RO-1205S and ROE-1205S are rated at 80% efficiency, which exceeds the IE1205S specification of 75%. The CRE1S1205SC is rated at 71% efficiency. Efficiency differences do not affect functional compatibility but may influence thermal management considerations in power-sensitive applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The CRE1S1205SC, RO-1205S, and ROE-1205S are all ROHS3 compliant, matching the primary part specification.

Q: What is the isolation voltage rating for these converters?

A: All parts, including the primary IE1205S and all substitute parts, maintain a 1 kV isolation voltage rating. This specification is consistent across all equivalent devices.

Q: Can these parts be used in applications outside the -40°C to 85°C temperature range?

A: No. All parts are specified for operation within -40°C to 85°C. Applications requiring extended temperature ranges require alternative component selection outside this product family.
