Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on identical or superior values for all functionally relevant electrical and mechanical parameters. Substitute groupings require exact input and output voltage ranges, output current, output power, isolation voltage, mounting method, package compatibility, and environmental and compliance status. Only parts meeting or exceeding these parameters may be considered equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both VIBLSD1-S24-S9-SIP and PQME1-S24-S9-S are listed as active status, RoHS compliant, and share the same main electrical and operational parameters including input voltage range, output voltage, output current, power rating, mounting type, and environmental compliance. Both are suitable for ITE (Commercial) applications. Package dimension differences need verification within the context of allowed mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: On what basis are substitute DC DC converters selected for VIBLSD1-S24-S9-SIP?
A: Substitutes are selected strictly on matching input voltage range, output voltage, output current, power rating, isolation voltage, mounting type, package form factor, environmental operating range, and compliance status.

Q: Are VIBLSD1-S24-S9-SIP and PQME1-S24-S9-S mechanically identical?
A: Both parts use SIP module packages with 4 leads and similar dimensions. The VIBLSD1-S24-S9-SIP uses a 6-SIP module, while PQME1-S24-S9-S uses a 7-SIP module.

Q: Do both models provide the same level of isolation?
