Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected based strictly on matching input voltage range, dual output voltages (+9V, -9V), and output current. Other key equivalence parameters include isolation voltage, mounting type, package/case, application (ITE Commercial), features such as short-circuit protection, efficiency within provided tolerance, and similar size. Compliance and regulatory statuses are also considered, enabling direct replacement for the original part VWRAS1-D24-D9-SIP.

Parameter Comparison

Engineering Selection Recommendations

VWRAS1-D24-D9-SIP is obsolete; direct substitution requires consideration of product status, compliance, and certifications. RSO-2409D/H2 by Recom Power is an active product, is ROHS3 compliant, and shares matching REACH, ECCN, and HTSUS statuses. Both parts support the same electrical parameters, mounting type, and package dimensions. Selection should be based on required product availability and regulatory compliance for specific applications.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if RSO-2409D/H2 can substitute VWRAS1-D24-D9-SIP?
A1: Substitution is based strictly on electrical parameters (input voltage, output voltages, output current, isolation), package type (8-SIP Module, 7 Leads), mounting type (Through Hole), and regulated application status.

Q2: Are there any differences in package size or pinout between these DC-DC converter modules?
A2: Both modules use an 8-SIP package with 7 leads. Provided physical dimensions are similar.

Q3: Is RoHS compliance different between the original part and the substitute?
A3: VWRAS1-D24-D9-SIP is listed as not applicable for RoHS, while RSO-2409D/H2 is ROHS3 compliant. Users should consider regulatory requirements.

Q4: Does the substitute part provide additional features not present in the original?
A4: RSO-2409D/H2 lists Remote On/Off control and an isolation voltage of 2 kV; VWRAS1-D24-D9-SIP provides 1.5 kV and does not explicitly include remote control.

Q5: Is there any difference in application suitability for ITE (Commercial)?
A5: Both parts are suitable for ITE (Commercial) applications. The substitute also supports Medical use per listed parameters.

Q6: Can the difference in output current (55mA vs. 56mA) affect compatibility?
A6: Both output currents meet or exceed the requirement specified by the original part.
