Is there a pin-compatible replacement for DS1009-28AT1NS-0A2?

Yes, parts like Z-ICS0S28P-NG00 are very likely pin-compatible as they share the standard narrow DIP-28 package footprint. However, pin-to-pin compatibility should be confirmed by reviewing the mechanical drawings in the datasheet.

What risks should I check before replacing DS1009-28AT1NS-0A2?

The main risk is mismatched row spacing. Ensure any replacement has a 7.62mm (0.3-inch) spacing to fit the PCB layout, not the wider 15.24mm (0.6-inch) version. Also check contact plating and material if your application is sensitive to them.

DS1009-28AT1NS-0A2 Alternatives, Datasheet & Cross Reference | CONNFLY

Finding a substitute for the CONNFLY DS1009-28AT1NS-0A2 28-pin DIP socket requires matching the narrow 7.62mm (0.3") row spacing. Several alternatives exist, but careful verification of mechanical dimensions is critical to ensure PCB compatibility.

AI replacement insight

Package riskhigh

DIP sockets commonly come in narrow (0.3") and wide (0.6") versions. Mismatching this dimension will cause assembly failure.

Electrical risklow

Most DIP sockets have similar, non-critical electrical properties for general use. Check current rating if relevant.

Can it be replaced directly?

Z-ICS0S28P-NG00 is a promising direct replacement, as it matches the package, pin count, and critical 7.62mm row spacing. Datasheet verification is still required.

Best replacement path

Prioritize candidates with a confirmed 7.62mm row spacing, such as Z-ICS0S28P-NG00, and verify datasheet details.

Main risk

The primary risk is selecting a socket with the wrong row spacing (e.g., 15.24mm), which would be mechanically incompatible with the PCB.

Recommended alternatives

A strong alternative with matching package, pin count, pitch, and row spacing.
