• Applications
  These parameters ensure electrical and mechanical compatibility between the RSS-053.3/HP and possible substitute parts.

Parameter Comparison

Engineering Selection Recommendations

The RSS-053.3/HP is classified as obsolete with ROHS3 and REACH compliance. The substitute part R1S-053.3/HP is active, maintains the same compliance and certification standards, and matches or exceeds all relevant parameters for electrical and mechanical compatibility as provided. Both products support ITE (Commercial) and Medical applications and conform to the same regulatory classifications.

Frequently Asked Questions (FAQ)

Q: What criteria determine whether a DC-DC converter is a suitable substitute?
A: Key criteria include input voltage range, output voltage and current, output power, isolation voltage, number of outputs, mounting type, package, and compliance status (RoHS, REACH).

Q: Does the R1S-053.3/HP match the package and mounting requirements of the RSS-053.3/HP?
A: Both parts utilize a surface mount configuration with an 8-SMD Module and 5 leads, though the size dimensions differ. Form factor should be evaluated strictly according to the provided measurements.

Q: Are there differences in electrical performance between the RSS-053.3/HP and R1S-053.3/HP?
A: According to all provided parameters, core electrical specifications such as voltage and current ratings, isolation, and efficiency remain consistent.

Q: Is regulatory compliance maintained with the substitute part?
A: Both RSS-053.3/HP and R1S-053.3/HP are listed as ROHS3 compliant and are unaffected by REACH, with the same ECCN and HTSUS classifications.

Q: Can the part be substituted in medical and ITE applications?
A: Both the original and substitute parts are specified for ITE (Commercial) and Medical applications as per the provided parameters.

Q: Are there differences in operating temperature?
A: The R1S-053.3/HP supports a wider operating temperature range (-40°C ~ 100°C) compared to the RSS-053.3/HP (-40°C ~ 85°C). This can impact application suitability within the allowable parameter set.
