Equivalent & Substitute Parts Reference: PSK-S15C-3

Part Overview

The PSK-S15C-3 by CUI Inc. is an enclosed AC/DC converter with an output of 3.3V at 2.7A, supporting input voltages of 85 ~ 264 VAC and 100 ~ 370 VDC. The product offers 8.9W power output, through hole mounting, universal input compatibility, and certifications including CB Scheme, EN, IEC, UL. The PSK-S15C-3 is listed as Obsolete, necessitating the consideration of substitute parts with equivalent or improved performance parameters to ensure continued availability and direct compatibility in applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly validated on the basis of electrical and mechanical parameters, including output voltage, output current, input voltage range, number of outputs, mounting type, and enclosure. Certification and compliance status, as well as physical packaging, are included as allowed parameters. Only substitute parts meeting or exceeding these values are listed. The listed substitute, PSK-15D-3, matches the output voltage, output type, mounting, and exceeds output current and input voltage ranges.

Parameter Comparison

Engineering Selection Recommendations

The PSK-S15C-3 is classified as obsolete, and the recommended substitute PSK-15D-3 is currently active and in production. Both parts are ROHS3 compliant and REACH unaffected. Approval agencies differ, requiring verification if system certification alignment is mandatory, but both contain safety and compliance certifications suitable for similar markets. Substitution suitability relies on comparison of mounting type, enclosure, output voltage, input voltage range, and single output configuration, all of which are maintained or exceeded in the substitute model.

Frequently Asked Questions (FAQ)

Q1: What input voltage ranges are supported by PSK-S15C-3 and PSK-15D-3 in substitution?
A1: PSK-S15C-3 supports 85 ~ 264 VAC, 100 ~ 370 VDC. PSK-15D-3 supports 85 ~ 305 VAC, 100 ~ 430 VDC.

Q2: Are the output voltages and current ratings identical between the original and substitute parts?
A2: Both parts provide a single 3.3V output. PSK-15D-3 supports up to 4A, exceeding PSK-S15C-3's 2.7A rating.

Q3: Do the mechanical mounting and package options allow direct replacement?
A3: Both parts use through hole mounting and enclosed module packages. Package dimensions are similar though not identical. Review physical compatibility.

Q4: Are RoHS and REACH compliance statuses consistent across both parts?
A4: Both PSK-S15C-3 and PSK-15D-3 are ROHS3 compliant and REACH unaffected.

Q5: Are there differences in approval agency certification between these models?
A5: PSK-S15C-3 carries CB Scheme, EN, IEC, UL approvals. PSK-15D-3 carries CE and cURus approvals. Review certification requirements if needed for system use.

Q6: Is it necessary to consider operating temperature range for substitution?
A6: PSK-S15C-3 is rated for -40°C ~ 70°C with derating. PSK-15D-3 provides -40°C ~ 85°C with derating. Ensure suitability for application environment.
