Key Parameters

Substitute Part Grouping Explanation

Substitute models are selected by direct matching of the following key allowed parameters: input voltage range, output voltage, output configuration, mounting and package type, operating temperature range, and RoHS compliance. Current output and power must equal or exceed those of the obsolete part. Isolation voltage, efficiency, and exact dimensions vary within the group but are used only as listed.

Parameter Comparison

Engineering Selection Recommendations

CES48120-6-R is listed as obsolete and ROHS3 compliant, requiring replacement for continuity. CHS804812-R is active, shares the same compliance standards (ROHS3, ECCN EAR99, HTSUS 8504.40.9580), input/output voltage ranges, output configuration, package type, mounting, and operating temperature range. Certification, compliance, and package conformity meet substitution requirements.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for substitution?
Allowed substitution requires matching the input voltage range, output voltage, output configuration, mounting type, package/case, operating temperature range, and compliance certification.

Q2: Does the substitute part CHS804812-R provide an adequate replacement in mechanical and electrical terms?
