Equivalent & Substitute Parts Reference for CU10-12

Part Overview

The CU10-12 is an AC/DC converter manufactured by XP Power, categorized as an open frame, single-output power supply delivering 12V at up to 840mA (10W output). It features through-hole mounting in a 4-DIP module package compliant with ROHS3 standards and operates over a wide input range of 85 ~ 264 VAC. This unit serves in both ITE (Commercial) and medical applications. As the CU10-12 is listed as obsolete, sourcing drop-in, technically compliant substitute models is essential to ensure continuity of design, inventory maintenance, and regulatory alignment.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected by matching the following critical electrical and mechanical parameters: number of outputs (1), input voltage range (minimum 85 ~ 264 VAC), output voltage (12V), output current (minimum 840mA), power (minimum 10W), mounting type (through hole), package/case (4-DIP Module), intended applications (ITE, medical), basic efficiency (75%), line/load regulation, and RoHS3 compliance. Only listed substitute manufacturer part numbers meeting all these required parameters are included.

Parameter Comparison

Engineering Selection Recommendations

The CU10-12 is obsolete and listed as ROHS3 compliant. The substitute part PWC12-12 meets the required application classes (ITE, Medical), offers equivalent electrical and mechanical characteristics, and maintains ROHS3 compliance. Additionally, PWC12-12 provides active inventory status and relevant certification approvals (CE, cURus, UL), suitable for regulated environments. Both products carry ECCN: EAR99 and matching HTSUS codes, supporting direct replacement within existing compliance frameworks.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when substituting CU10-12 with PWC12-12?
Electrical characteristics (input voltage range, output voltage/current, power), mechanical attributes (mounting type, package), application compatibility, regulation performance, and compliance standards (RoHS3) must all be matched.

Q2: Is the physical package between CU10-12 and PWC12-12 compatible for direct replacement?
Both are specified as 4-DIP Module, through-hole mounting, which permits direct replacement within the same footprint class.

Q3: Does the substitute PWC12-12 support the same applications as CU10-12?
Yes, both are designed for ITE (Commercial) and medical use cases, aligning with regulated application domains.

Q4: Are there certification considerations for substitution?
PWC12-12 provides certification to CE, cURus, UL, with listed standards 60601-1 and 60950-1. For deployments requiring explicit certifications, these should align with site or regulatory requirements.

Q5: Do operating temperature differences affect substitution?
Both units function within derated temperature ranges, and substitute selection should consider the provided temperature specification for system compatibility.

Q6: Is RoHS compliance maintained after substitution?
Both CU10-12 and PWC12-12 are listed as ROHS3 compliant, supporting continued environmental compliance.
