5-Pack 303-1AH-C-R1-U01 12V 20A SPST-NO Ultra Micro Automotive Relays

$ 39.95

Product Description

Set of five replacement ultra-micro automotive relays compatible with the specifications of Song Chuan 303-1AH-C-R1-U01-12VDC. Designed for compact automotive and equipment power-distribution applications requiring a 12-volt coil, normally open contacts and a 20-amp resistive switching capacity.

These are unbranded aftermarket replacements. They should not be advertised as genuine Song Chuan components unless the relay markings or manufacturer packaging confirm authenticity.

Compatibility Notice

This is an electrical component and does not have universal vehicle fitment. Before ordering, compare the complete number and specifications of your original relay:

303-1AH-C-R1-U01-12VDC

Also verify:

12V DC coil voltage
20A contact requirement
SPST normally open operation
Terminal count, size and orientation
Socket footprint and housing dimensions
Presence of the internal suppression resistor

A relay with a similar exterior may have a different terminal layout, contact configuration or suppression device. Do not substitute solely by appearance.
