Is there a pin-compatible replacement for TX2-5V?

A pin-compatible replacement has not been verified. The Panasonic TQ and TX series have different package dimensions (TQ2: 14x9mm, TX2: 15x7.4mm), so they are not pin-compatible despite both being DPDT through-hole relays.

What risks should I check before replacing TX2-5V?

Before replacing, you must verify: 1) Coil Voltage (must be 5V), 2) Contact Current Rating (must be 2A or more), 3) Package Dimensions and Pinout (must match the 15.0 x 7.4 mm footprint), and 4) Coil Type (must be non-latching).

TX2-5V Alternatives, Datasheet & Cross Reference | PANASONIC

Finding a substitute for the Panasonic TX2-5V signal relay requires matching its 5V coil, DPDT contacts, and 2A rating. Key challenges include finding parts with identical package dimensions and electrical ratings.

AI replacement insight

Electrical riskhigh

Candidates often have lower current ratings, posing a reliability risk.

Package riskhigh

Footprints for signal relays are varied and must be matched exactly.

Can it be replaced directly?

No direct drop-in replacement has been identified. The closest functional match, TQ2-5V, has a lower current rating and a different package, making it unsuitable for many applications without redesign.

Best replacement path

The best path is to find another relay from a major manufacturer with a 5V coil, DPDT contacts, a 2A or higher current rating, and a matching 15.0 x 7.4 mm footprint.

Main risk

The primary risks are electrical overstress due to lower current ratings and mechanical incompatibility from different package footprints.

Recommended alternatives

A functional alternative with the same 5V coil, but has a lower 1A current rating and different package size.

Questions & answers

Currently, no direct drop-in alternative is confirmed. The Panasonic TQ2-5V has a matching 5V coil but a lower 1A current rating and different package. Reviewing other 2A relays like the Omron G6S series for a 5V version is recommended.
