Is there a pin-compatible replacement for DB301V-3.81-2P-GN-S?

There are several potential form-fit-function replacements like XY303V-3.81-2P and DB2EKM-3.81-2P-GN-S, which match key specs. However, none are verified as pin-compatible without a manual check of the datasheet's mechanical drawing to confirm the PCB footprint.

What risks should I check before replacing DB301V-3.81-2P-GN-S?

Before replacing, you must check three main risks: 1) Mechanical Fit: Verify the substitute's PCB footprint and height from its datasheet. 2) Orientation: Ensure the wire entry is vertical like the original, not right-angle. 3) Wire Gauge: Confirm the substitute accepts your required wire size.

DB301V-3.81-2P-GN-S Alternatives, Datasheet & Cross Reference | Ningbo Dorabo Electric Co., Ltd.

Finding a substitute for the DORABO DB301V-3.81-2P-GN-S terminal block involves matching the critical 3.81mm pitch and 2-position configuration. Several functional alternatives are available with similar or better electrical ratings, but require careful verification of the mechanical footprint.

AI replacement insight

Package riskhigh

Footprint and orientation must be verified from datasheets as they are critical for terminal blocks and often vary.

Electrical risklow

Several candidates meet or exceed the voltage and current ratings of the target part.

Can it be replaced directly?

No direct, verified pin-to-pin replacement has been identified. Several functional alternatives exist but require engineers to verify the PCB footprint and orientation from the datasheet.

Best replacement path

XY303V-3.81-2P offers a strong parametric match with higher current and wider wire gauge support, but requires mechanical verification.

Main risk

The primary risk is mechanical incompatibility. Substitutes may have a different PCB footprint or orientation (e.g., right-angle vs. vertical) that will not fit the existing board layout.

Recommended alternatives

A potential alternative from the same manufacturer with stronger electrical specs; requires footprint verification.
