CXA-0549 Equivalent & Substitute Parts

Part Overview

The CXA-0549 is a CCFL and UV lamps inverter manufactured by TDK Corporation, designed for applications requiring 12V input conversion to 1500V output. This component operates within an input voltage range of 10.8 to 13.2V and is housed in a compact chassis-mount package measuring 140mm × 30mm × 8mm.

The CXA-0549 carries an obsolete product status, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement. Substitute parts must maintain electrical compatibility across input/output voltage specifications and physical mounting requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CXA-0549 is determined by the following critical parameters:

• Output Voltage: Must equal 1500V
• Application Type: Must support CCFL and UV lamps operation
• Mounting Configuration: Must be chassis mount
• Manufacturer Compatibility: TDK Corporation series parts
• Moisture Sensitivity: MSL 1 classification maintained

The CXA-M1112-VJ qualifies as a substitute based on matching output voltage (1500V), identical application type (CCFL and UV lamps inverter), and compatible chassis-mount configuration. Both components share MSL 1 moisture sensitivity classification and are manufactured by TDK Corporation within the CXA series.

Input voltage specification differs between the main part (10.8 ~ 13.2V range) and the substitute (fixed 12V nominal), representing a narrower input tolerance in the substitute model. This difference must be evaluated against system power supply characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CXA-M1112-VJ is the manufacturer-designated substitute for the obsolete CXA-0549. Both components deliver identical 1500V output for CCFL and UV lamp applications and maintain equivalent moisture sensitivity classification.

The substitute part carries active product status, ensuring continued availability and manufacturing support compared to the obsolete main part. Both components are classified under ECCN EAR99 and HTSUS 8504.40.9570.

Physical dimensions differ between the two models. The CXA-M1112-VJ measures 180.3mm × 24.6mm × 8mm compared to the CXA-0549 at 140mm × 30mm × 8mm. Mechanical integration verification is required to confirm fit within existing chassis or enclosure designs.

Input voltage specification requires evaluation. The CXA-0549 accepts a 10.8 to 13.2V range, while the CXA-M1112-VJ operates at 12V nominal. System power supply regulation and tolerance must be confirmed to ensure the substitute operates within specified input parameters.

Frequently Asked Questions (FAQ)

Q: Can the CXA-M1112-VJ directly replace the CXA-0549 in existing designs?

A: Electrical compatibility is established through matching 1500V output and CCFL/UV lamp application type. Physical dimensions differ, requiring verification that the substitute fits within the available mounting space. Input voltage tolerance differences must be evaluated against system power supply specifications.

Q: What is the significance of the product status difference?

A: The CXA-0549 is obsolete, indicating discontinued manufacturing and limited future availability. The CXA-M1112-VJ maintains active status, ensuring ongoing supply and manufacturing support for new procurements and system maintenance.

Q: Are there compliance differences between these components?

A: The CXA-M1112-VJ is classified as RoHS non-compliant. Both components share identical ECCN and HTSUS classifications. Regulatory requirements for your application must be verified independently.

Q: How do input voltage specifications affect substitution?

A: The CXA-0549 accepts 10.8 to 13.2V input, providing a ±10% tolerance window around 12V nominal. The CXA-M1112-VJ operates at 12V fixed specification. System power supply regulation must maintain output within the substitute's operating range.

Q: What packaging differences exist?

A: The CXA-0549 packaging specification is not provided. The CXA-M1112-VJ is supplied in bulk packaging. Procurement requirements for tape, reel, or alternative packaging formats should be confirmed with the supplier.
