QH04CT-12 Equivalent & Substitute Parts Reference

Part Overview

The XP Power QH04CT-12 (DC DC CONVERTER 200V -200V 1.25W) is a high voltage isolated DC-DC converter module intended for ITE (Commercial) applications. The product provides two isolated outputs of +200V and -200V, each capable of sourcing up to 3.125mA, with an input range of 0.7V to 12V. The converter is built in a 6-DIP through-hole package, with specified dimensions, and is ROHS3 compliant.

The QH04CT-12 is currently obsolete. Engineering teams requiring maintenance, replacement, or second-sourcing of this exact specification must identify substitute DC-DC converters with electrical and mechanical compatibility. The necessity arises from the product's end-of-life status, impacting availability for new projects and ongoing maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the QH04CT-12 is governed by strict adherence to user-supplied electrical and mechanical parameters. Only devices matching the following criteria are considered:

• Type: High Voltage - Isolated Module DC DC Converter
• Input Voltage Range: 0.7V - 12V
• Output Voltages: 200V, -200V (dual outputs)
• Maximum Output Current: per channel specification
• Maximum Output Power: defined wattage or lower
• Isolation Voltage: 500V
• Package: 6-DIP Module, Through Hole
• Mechanical Dimensions: 0.50" x 0.50" x 0.50"
• Application Category: ITE (Commercial)
• ROHS3 Compliance

Only part numbers matching these electrical and mechanical characteristics are considered direct substitutes here.

Engineering Selection Recommendations

The XP Power QH04CT-12 is classified as obsolete. When a direct substitute is required within the same category, only parts matching provided compliance, package, and certification criteria should be selected. Q04CT-12 is active, ROHS3 compliant, and meets size and package requirements in the same category as the main part, aligning with standard regulatory and handling profiles.

Frequently Asked Questions (FAQ)

Q: What are the primary substitution criteria for the QH04CT-12 DC-DC converter?
A: Allowed substitutions must match the electrical parameters (input voltage range, output voltages, isolation voltage, number of outputs, and maximum output current/power), mechanical parameters (package type, mounting method, physical dimensions), and compliance status.

Q: Is package compatibility guaranteed when substituting QH04CT-12 with Q04CT-12?
A: Both parts have a 6-DIP module package and identical mechanical dimensions (0.50" x 0.50" x 0.50"), with through hole mounting, fulfilling physical package compatibility requirements.

Q: Are there differences in electrical capability between QH04CT-12 and Q04CT-12?
A: QH04CT-12 supports up to 3.125mA per output at 1.25W, while Q04CT-12 provides 1.25mA per output at 500mW. This distinction in maximum output current and wattage must be considered when assessing functional compatibility.

Q: Is ROHS3 compliance maintained when selecting the substitute part?
A: Both QH04CT-12 and Q04CT-12 are ROHS3 compliant.

Q: Are substitute parts in this category intended for the same application type?
A: Both models are specified for ITE (Commercial) applications.

Q: Are remote on/off or proportional output features retained?
A: QH04CT-12 features proportional output and remote on/off. Q04CT-12 lists proportional output. Retention of all features is dependent on supplied parameters. Only those explicitly provided have been considered for substitution criteria.
