5pcs PCH-112L2MH Relay 12VDC PCB Power Relay SPST-NO (1 Form A) 5A 4-Pin Through-Hole Solder Relay Replacement, Alt P/N PCH-112L2MH,000/1461353-5, Module Repair

PCH-112L2MH 12VDC PCB Power Relay (SPST-NO)This is a PCB-mount (through-hole) power relay intended to replace the same relay part number on an electronic board/module. It is not a blade-terminal plug-in relay.Key SpecsPart number: PCH-112L2MH (alt markings may include PCH-112L2MH,000 / 1461353-5)Coil: 12VDC sensitive coil, 200 mW, 720 ohmContacts: SPST-NO (1 Form A), 5A contact rating, max switching 30VDC / 277VACTerminals: 4-pin through-hole solder pins (THT)Size: approx. 20 x 10 x 15.2 mm; sealed "H" style coverWhat it doesSwitches power to a load when the 12V coil is energized. Commonly used as a general-purpose relay on control boards where compact size and stable switching are needed.Common Symptoms of a Failed RelayIntermittent operation (works sometimes, fails when warm)No output to the load even when the control signal is presentRelay does not actuate/click during testing, or contacts show high resistanceFitment & Installation NotesConfirm fitment by the OE/part number printed on your original relay, your vehicle/service manual, and the PCB footprint (pin layout). Match coil voltage (12VDC) and contact form (SPST-NO) before soldering. Disconnect power before servicing electronics.

• Specs: PCH-112L2MH 12VDC PCB power relay with sensitive coil (200 mW, 720 ohm), SPST-NO (1 Form A) contact, 5A contact rating, max switching 30VDC / 277VAC, operate/release <=10ms/<=5ms, AgSnO2 contacts, min load 100mA @ 5V. Electrical: 4000Vrms coil-to-contact insulation (750Vrms open contacts), frequency up to 360 ops/hr, mechanical endurance up to 10 million ops, ambient rated up to 85C, wave-solder capable up to 265C. Monostable, wash-tight sealed cover, 4-pin through-hole solder terminals, compact 20 x 10 x 15.2 mm. OE/Part No: PCH-112L2MH / PCH-112L2MH,000 / 1461353-5; choose only if markings, ratings, and footprint match your board.
• Install tips (PCB relay): Disconnect battery before removing any control module. Open the module/relay board, note relay orientation, then desolder the old relay (solder wick/hot air), clean pads, and solder the new relay flush to the PCB with solid joints. Verify coil is 12VDC (typical operate ~9V, release ~0.6V) and contacts are SPST-NO (normally open) before reassembly. Common placement: inside electronic control modules or relay boards where relays are soldered to the PCB (not a blade-terminal plug-in relay). After install, check continuity across contact pins while energizing the coil, inspect for lifted pads/bridges; confirm fitment by OE number and your service manual.
• Compatible with relays marked PCH-112L2MH used on PCB-mounted relay boards/control modules where a 12VDC coil, SPST-NO (1 Form A) contact, and 4-pin through-hole (THT) solder-pin footprint are required. Confirm fitment by matching: printed part number (PCH-112L2MH / PCH-112L2MH,000 / 1461353-5), case size ~20 x 10 x 15.2 mm, pin layout on your PCB, and the electrical ratings (5A contact, max 30VDC switching). Designed for board-level power switching in general-purpose circuits; great for module repair when the relay on the board is heat-damaged or intermittent. If your application uses a blade-terminal 4/5-pin plug-in socket relay, this PCB relay will not interchange - verify style first.
• Compatible with general-purpose control boards that need a compact 12VDC SPST-NO power relay, including appliance and HVAC control boards (examples: air conditioner, refrigerator, microwave control PCB) when the board specifies PCH-112L2MH.

For automotive electronics use, confirm the exact relay marking/OE number and PCB footprint on your module before ordering; this is not a blade-terminal plug-in relay.
• Compatible with buyers searching related PCH series PCB relays for board repair - verify suffix/specs before substituting. Related PCH family examples include: PCH-112L2M,000 (sensitive, flux proof), PCH-112L2M-WG (flux proof, IEC 60335-1), PCH-112D2,000 (standard coil, 1 Form C), PCH-112D2H,000 (wash tight), PCH-112D2M,000 (1 Form A), PCH-112D2MH,000, PCH-105L2MH,000 (5V coil), and 24V coil versions such as PCH-124L2MH,000 / PCH-124D2M,000 / PCH-124D2MH,000. Use these only as search references: do NOT assume interchangeability. Replace only when coil voltage, contact arrangement (SPST-NO vs CO), and protection style (H = sealed) match your original relay and your PCB footprint.
