A 3-position, 5.0mm pitch terminal block with a lower voltage rating (250V) but slightly higher current rating (16A).
Best Alternatives to DB127V-5.0-3P-GN-S
DB127V-5.0-3P-GN-S is a 3-position, 5.0mm pitch PCB terminal block rated for 300V and 15A. Finding a suitable replacement requires strictly matching the pitch, voltage, and current to ensure mechanical fit and electrical safety.
AI replacement insight
Package riskhigh
High risk of selecting a 5.08mm pitch part which is mechanically incompatible. Mounting orientation must also be verified.
Electrical riskmedium
Candidates often have lower voltage or current ratings, which requires careful engineering review to ensure safety and reliability.
Can it be replaced directly?
No direct, drop-in replacement for DB127V-5.0-3P-GN-S was identified. All potential alternatives have significant electrical or mechanical differences.
Best replacement path
Reviewing candidates with the same 5.0mm pitch but potentially lower electrical ratings, like MX126R-5.0-03P-GN01-Cu-S-A, if the application allows.
Main risk
The primary risk is selecting a part with the wrong pitch (5.08mm instead of 5.0mm), followed by electrical downgrades in voltage or current ratings.
