Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ZTS1R54812 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Output voltage specification of 12V
• Output current capacity of 130mA minimum
• Input voltage range encompassing 36V to 72V operation
• Isolation voltage rating of 500V or greater

Physical and Mechanical Requirements:

• Through hole mounting capability
• Package footprint compatibility with 6-pin DIP or equivalent module configuration

Compliance and Quality Requirements:

• RoHS3 compliance status
• Active product status for ongoing availability
• Commercial ITE application suitability

The MGS1R54812 satisfies all substitution criteria through equivalent electrical performance, enhanced specifications, and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: MGS1R54812

The MGS1R54812 serves as the direct functional equivalent for the obsolete ZTS1R54812. Both components are manufactured by Cosel USA, Inc., and deliver identical electrical performance specifications for 12V output at 130mA from 36V to 72V input sources.

The MGS1R54812 provides enhanced performance characteristics across multiple parameters: extended isolation voltage (1.5 kV versus 500V), improved efficiency (82% versus 73%), and expanded operating temperature range (-40°C to 85°C versus -20°C to 71°C). These enhancements ensure superior reliability and operational margin in commercial ITE applications.

Package Consideration:

The substitute part utilizes a 6-SIP module configuration with 4 leads, whereas the original part employs a 6-DIP module package. PCB layout modifications are required to accommodate the different footprint. Physical dimensions differ: the MGS1R54812 measures 17.0mm × 8.5mm × 12.0mm compared to the ZTS1R54812 at 28.0mm × 10.0mm × 21.0mm. Design review of board-level integration is necessary prior to implementation.

Compliance Status:

The MGS1R54812 carries CE, cUL, cURus, and DEMKO approvals with compliance to IEC 60950-1 standard. The original ZTS1R54812 maintains ROHS3 compliance. Verification of RoHS compliance status for the MGS1R54812 is recommended during procurement specification.

Frequently Asked Questions (FAQ)

Q: Can the MGS1R54812 directly replace the ZTS1R54812 without circuit modifications?

A: Electrical substitution is direct; however, physical package differences require PCB layout modifications. The MGS1R54812 uses a 6-SIP configuration versus the 6-DIP module of the original part, necessitating footprint redesign.

Q: What are the key electrical advantages of the MGS1R54812 substitute?

A: The substitute provides three measurable improvements: isolation voltage increases from 500V to 1.5 kV, efficiency improves from 73% to 82%, and operating temperature range expands from -20°C to 71°C to -40°C to 85°C. These enhancements deliver greater design margin and thermal performance.

Q: Are both parts suitable for the same commercial ITE applications?

A: Yes. Both the ZTS1R54812 and MGS1R54812 are specified for commercial ITE applications. The substitute's enhanced specifications make it suitable for applications requiring extended temperature operation or higher isolation requirements.

Q: What is the significance of the input voltage range difference (72V maximum versus 76V maximum)?

A: The MGS1R54812 accepts input voltages up to 76V, exceeding the original specification of 72V. This provides additional operational margin for systems with input voltage variations. Applications operating within the original 36V to 72V range experience no functional difference.

Q: How do the physical dimensions affect board design?

A: The MGS1R54812 is significantly smaller (17.0mm × 8.5mm × 12.0mm) compared to the ZTS1R54812 (28.0mm × 10.0mm × 21.0mm). This reduction in size may provide layout benefits; however, the different pin configuration requires complete footprint redesign rather than direct socket replacement.

Q: What compliance certifications should be verified for the MGS1R54812?

A: The MGS1R54812 carries CE, cUL, cURus, and DEMKO approvals and complies with IEC 60950-1. Confirmation of RoHS3 compliance status is recommended to match the original part's environmental specifications.

Q: Is the 1.56W power rating of the MGS1R54812 equivalent to the 1.6W rating of the ZTS1R54812?

A: Yes. The power ratings are functionally equivalent within normal engineering tolerance. Both parts deliver the required 12V at 130mA output current for commercial ITE applications.
