Is there a pin-compatible replacement for DB2EK-3.81-4P-GN-S?

While several parts have the same 3.81mm pitch and 4-pin layout, true pin-to-pin compatibility requires comparing mechanical drawings to ensure the housing and contacts align perfectly. No replacements are verified as drop-in without this check.

What risks should I check before replacing DB2EK-3.81-4P-GN-S?

The main risk is mechanical incompatibility. Verify the candidate's housing dimensions, wire entry orientation (e.g., vertical), and any locking features against the target's datasheet and your application's space constraints.

DB2EK-3.81-4P-GN-S is a 4-position, 3.81mm pitch pluggable terminal block rated for 300V/8A. Alternatives with similar electrical and mechanical properties are available but require datasheet verification for fit.

AI replacement insight

Package riskmedium

Housing dimensions and locking features must be verified from datasheets.

Electrical risklow

Key electrical ratings match the target.

Can it be replaced directly?

No verified direct drop-in replacement exists. Several functional alternatives with matching key specs are available but require mechanical verification.

Best replacement path

Use a functional alternative like WJ15EDGVM-3.81-04P-14-00A after verifying mechanical drawings from the datasheet.

Main risk

Mechanical mismatch. The housing dimensions or locking mechanism of an alternative may not be identical.

Recommended alternatives

A 4-position, 3.81mm pitch pluggable block with matching electrical ratings. Verify mechanical fit.
