Key Parameters

Substitute Part Grouping Explanation

Substitute models for the PSS3-5-12 are identified strictly based on matching the following electrical and mechanical parameters: input voltage range (4.5V - 9V), output voltage/functionality (12V, or compatible adjustable 12 ~ 15V), output current (250mA), power rating (3W), number of outputs (1), mounting type (Through Hole), package type (DIP Module), applications (ITE Commercial), and operating temperature range (-40°C ~ 85°C). Only substitute parts provided within these boundaries are considered equivalent.

Parameter Comparison

Engineering Selection Recommendations

The PSS3-5-12 Isolated Module DC DC Converter is obsolete. Substitute part CC3-0512SF-E is an active model with comparable key electrical and mechanical specifications. Both PSS3-5-12 and CC3-0512SF-E are RoHS compliant and classified under ECCN EAR99 and HTSUS 8504.40.9580. These parameters align with regulatory and compliance requirements included in the input.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a valid DC-DC converter substitution?
A1: Input voltage range, output voltage, output current, power rating, number of outputs, mounting type, package/case, and operating temperature range must match for a substitution to be valid.

Q2: How does package type affect compatibility?
A2: Both main and substitute parts are DIP modules with through hole mounting. Ensure footprint and pin configuration alignment before direct replacement.

Q3: Is there a difference in output voltage specifications between PSS3-5-12 and CC3-0512SF-E?
A3: PSS3-5-12 provides a fixed 12V output. CC3-0512SF-E specifies an output range of 12 ~ 15V. Select according to specific output voltage requirements.

Q4: Does operating temperature range differ?
A4: Both parts support -40°C to 85°C operation, meeting industrial and commercial thermal performance requirements as specified.

Q5: Are there differences in compliance or regulatory status?
A5: Both models are classified as EAR99 and listed under the same HTSUS code. The CC3-0512SF-E also meets RoHS compliance.

Q6: What is the impact of product status on sourcing?
A6: PSS3-5-12 is obsolete. Substitute CC3-0512SF-E is active and suitable for ongoing or new design-in based on provided parameters.
