Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Automotive and equipment circuits originally using SLDH-12VDC-1C
  • Custom 12V control systems with the identical terminal footprint and load rating
  • Not vehicle-specific; electrical specifications determine fit

Product Overview

Fans, pumps, lights, winches, and other high-current loads can stop working even when the control switch still sends voltage. If testing shows the relay coil or contacts have failed, matching the exact SLDH pinout is more important than matching the outer case alone.

Each relay provides common, normally open, and normally closed switching. Actual safe load depends on wiring size, socket condition, duty cycle, heat, and the device being controlled; never increase fuse size to compensate for a hot or damaged connector.

Key Features & Performance

  • Two changeover power relays
  • 12VDC coil
  • 80A normally open contact rating at 14VDC
  • 60A normally closed contact rating at 14VDC

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.

Frequently Asked Questions

Q: Can this replace any five-pin automotive relay? A: No. Pin position, coil suppression, contact form, and current rating must all match.

Q: Why did the original relay melt? A: Loose terminals, excessive load, undersized wire, poor ventilation, or a failing motor can generate damaging heat.

Q: How do I confirm this is the correct part? A: Match SLDH-12VDC-1C, coil voltage, terminal diagram, footprint, contact form, current rating, and socket keying.

Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
