Key Parameters

Substitute Part Grouping Explanation

Substitution for PSS3-48-12 is based strictly on these key parameters: input voltage range, output voltage specification, output current capability, power rating, mounting type, number of outputs, package type, operating temperature range, application classification, and compliance (MSL, ECCN, HTSUS). Only parts matching these parameters are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Main part PSS3-48-12 is obsolete; substitutes such as CC3-4812SF-E are in active product status. Both parts are compliant with RoHS, have an MSL rating of 1 (Unlimited), and are classified as EAR99 for ECCN and 8504.40.9580 for HTSUS. These factors support selecting an active substitute with matching compliance and certification data.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for selecting a substitute for PSS3-48-12?
A1: Input voltage range, output voltage and current ratings, power rating, number of outputs, mounting type, package, operating temperature, and compliance certifications are the critical parameters.

Q2: Is package compatibility a concern between PSS3-48-12 and CC3-4812SF-E?
A2: PSS3-48-12 uses a 6-DIP module, while CC3-4812SF-E uses a 7-DIP module. Dimensional differences should be considered for mechanical footprint compatibility in PCB layouts.

Q3: Does the substitute provide the same output voltage and current capability?
A3: CC3-4812SF-E supports an output voltage range of 12 ~ 15V at up to 250mA, matching the main part's base requirements for 12V 250mA.

Q4: Are both parts suitable for commercial ITE applications?
A4: Both PSS3-48-12 and CC3-4812SF-E are specified for ITE (Commercial) applications.

Q5: Do both devices comply with required MSL and regulatory certifications?
A5: Both devices are MSL 1 (Unlimited) and classified as EAR99 for ECCN and 8504.40.9580 for HTSUS.

Q6: Why is substitution necessary?
A6: PSS3-48-12 is obsolete; substitution is needed to ensure ongoing operational and supply chain continuity.
