DHD990H03B/1 filter element: specifications & equivalents

Q: What are the dimensions of the DHD990H03B/1 filter element?

The published envelope is 90.5 mm OD × 485 mm length with a 48.1 mm inside diameter (3.563 × 19.094 in × 1.894 in ID). Confirm against the housing drawing before ordering.

Q: What micron rating does DHD990H03B/1 use?

This element is rated 5 µm absolute — β5(c)≥1000. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

The DHD990H03B/1 is a Filtrec inline-line hydraulic filter element, built with glassfiber media, sized 90.5 × 485 mm OD × length (ID 48.1 mm), rated at 5 µm absolute (β5(c)≥1000). Verify against the current manufacturer data sheet before ordering.

Catalog verified. Parameters extracted from the manufacturer’s electronic catalog / official interchange document and checked 2026-10-03. Confidence score 0.90.

Dimensions and media grade are taken from Filtrec’s official Cross Navigator, which maps this element to specific competitor part numbers. Filtrec does not publish collapse pressure or seal compound in this API for every code — verify collapse rating, seal execution and bypass setting against the current Filtrec data sheet for the target housing before ordering.

Selection pitfalls — read before you substitute

“10 µm nominal” and “12 µm at β1000” can describe the very same media — one is reported at β≥200, the other at β≥1000 per ISO 16889. Compare ratings at the same Beta test point, not just the printed micron number.
Fine 5 µm media loads faster and runs at a higher cold Δp than coarser grades — only downgrade cleanliness targets if the system ISO 4406 code allows it.

Frequently asked questions

What are the dimensions of the DHD990H03B/1 filter element?

The published envelope is 90.5 mm OD × 485 mm length with a 48.1 mm inside diameter (3.563 × 19.094 in × 1.894 in ID). Confirm against the housing drawing before ordering.

What micron rating does DHD990H03B/1 use?

This element is rated 5 µm absolute — β5(c)≥1000. Always compare Beta ratings at the same test point: two brands may print different micron numbers for the same physical grade.

What replaces the DHD990H03B/1 filter element?

Cross references are being verified for this model — use the inquiry form and the engineering desk will confirm equivalents.

Is a same-envelope aftermarket element always a drop-in replacement?

No. Matching OD and length only proves the cartridge fits the bowl. End-cap style, seal compound, micron/Beta rating, collapse pressure and bypass configuration must also match; the table above tags every equivalent as full, partial or verify for exactly this reason.
