Key Parameters

Substitute Part Grouping Explanation

For DC-DC converters in this category, potential substitutes are determined by strict alignment of functional parameters. Parameters used for substitution include: type (isolated module), number of outputs, output voltage (12V), output current rating (minimum 83mA), input voltage range encompassing the original, power rating (1W), isolation voltage (≥1kV), mounting type (through-hole), and package considerations. Compliance with RoHS and intended application (ITE Commercial) are also required.

Parameter Comparison

Engineering Selection Recommendations

The original part, VIBLSD1-S5-S12-DIP, has reached obsolete status, requiring replacement selection for ongoing production and support. Substitute PDSE1-S5-S12-D from CUI Inc. is active, RoHS-compliant, and matches the core functional and electrical requirements. Both parts suit ITE (Commercial) applications and offer through-hole mounting. Parameter comparison confirms compatibility according to supplied input, product status, application, and compliance certifications.

Frequently Asked Questions (FAQ)

What are the key substitution criteria for VIBLSD1-S5-S12-DIP?

Only parts matching type (isolated DC-DC converter), output voltage (12V), current rating (≥83mA), input voltage range (inclusive of 4.75V–5.25V), power (1W), and mounting (through-hole) are considered equivalent substitutes. Application and RoHS compliance are also required.

Are there differences in package size or pinout between VIBLSD1-S5-S12-DIP and its substitute?

The VIBLSD1-S5-S12-DIP uses a 14-DIP Module (300 mil, 5 Leads), while the substitute PDSE1-S5-S12-D is supplied in an 8-DIP Module with 4 leads. Review of mechanical drawings and form factor dimensions is necessary to ensure suitability.

Is the substitute part PDSE1-S5-S12-D active and compliant?

PDSE1-S5-S12-D is listed as active and RoHS compliant, matching the compliance requirements of the original.

Can the substitute be used in the same applications?

Both parts are designated for ITE (Commercial) applications with matching core parameters as per provided input.

What are the isolation and efficiency differences?

PDSE1-S5-S12-D offers a higher isolation voltage (3 kV vs. 1 kV) and increased efficiency (83% vs. 71%) based on the provided data.
