CU15-14 Equivalent & Substitute Parts

Part Overview

The XP Power CU15-14 is an open frame AC/DC converter, supplying a single 24V output at up to 630mA, with a maximum power rating of 15W. Designed for ITE (Commercial) and medical applications, this converter offers wide input voltage (85 ~ 264 VAC) and through-hole mounting in a 4-DIP module package. The CU15-14 is now listed as obsolete, necessitating the identification of suitable substitute parts to ensure ongoing availability for existing and future designs that require equivalent electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly by matching key input and output electrical parameters, application conformity, compliance status, and physical mounting and package similarities. The key parameters for equivalence are:

• Type (Open Frame)
• Number of Outputs (1)
• Input Voltage Range (must fully cover or be within original range)
• Output Voltage (24V)
• Output Current (must be at least 630mA or higher)
• Power Rating (must be at least 15W or higher)
• Applications (must include ITE (Commercial) and Medical)
• Mounting Type (Through Hole)
• Package / Case (module standards suitable for open frame converters)
• RoHS Compliance
• Standard Number or equivalent safety certification
• Regulation (Line and Load regulation within same magnitude)

Parameter Comparison

Engineering Selection Recommendations

The primary driver for substitution is the obsolescence status of the XP Power CU15-14. The Cincon CFM21S240 is listed as active, is ROHS3 compliant, and includes ITE (Commercial) and Medical application ratings. Both parts meet comparable regulatory and safety standards. Package, mounting type, and output parameters fall within the required operational envelope, supporting direct substitution within the specified application category and compliance requirements.

Frequently Asked Questions (FAQ)

Q1: Which parameters must match when substituting AC/DC module power supplies in this category?
A1: The essential parameters are type (open frame), number of outputs, input voltage range, output voltage, maximum output current, power rating, application approvals, mounting type, package/case compatibility, RoHS compliance, relevant safety standard numbers, and regulation specifications.

Q2: Are package and mounting methods critical for compatibility?
A2: Yes. Both the module form factor and through-hole mounting must be matched to ensure proper mechanical and electrical integration in the host system.

Q3: Can substitute parts support the same applications as the original?
A3: Substitute parts listed provide support for ITE (Commercial) and Medical applications, matching the original component's application profile.

Q4: How does standard number equivalence affect substitution?
A4: Substitute parts must hold equivalent or additional safety and application certifications to ensure continued compliance in regulated environments.

Q5: Does a different maximum output current or power rating affect substitution?
A5: Substitute parts must provide output current and power equal to or greater than the original specification within the same output voltage, ensuring compatible operation for replacement.
