Compare the construction, not only the category name.

Select up to three SUNPU product directions. Use the result to identify specification gaps before requesting samples or a quotation.

Choose models

Build a working shortlist.

Products from different families can be compared, but a valid substitute must still be reviewed against the same system role, interface, performance target, and environment.

Side-by-side review

1 selected product.

Blank or different fields are review points—not automatic failures. Confirm the exact quoted construction and model-level evidence before approval.

Use the shortlist

Turn the comparison into a model review.

Send the selected models together with the application, quantity, destination, target standard, required documents, and any reference specification. SUNPU can then confirm which differences matter for the quotation.

Same label ≠ same construction

Category names can hide differences in conductor, shielding, connector, jacket, test basis, and packaging.

Missing field = question

A field not shown on the website should be confirmed in the quotation or controlled specification, not guessed.

System role comes first

Compare products that perform the same job in the channel and verify surrounding-component compatibility.

Evidence follows the model

Certificates, declarations, reports, and inspection records must be checked against the selected construction.
