Description

Parameters & footprint — Sealed PCB power relay 953-1A-12DG-2 (953G series): coil 12VDC (≈0.9W), coil resistance 155 Ω, nominal coil current ≈77 mA, pick-up ≤9 V, drop-out ≥1.2 V; contact arrangement 1 Form A (SPST-NO) up to 30 A resistive at 250 VAC or 30 VDC (max switching 250 VAC/30 VDC); Ag-alloy contacts; electrical life 100k ops, mechanical life 10M ops; two common terminals / 5-pin layout for low contact resistance; body ~27.4 × 31.8 mm; RoHS. Compatible with HSINDA 953G sealed 5-pin footprints on control boards.
Installation & location — PCB-mounted relay typically located on HVAC/appliance/industrial control boards (e.g., compressor, blower, heater, pump, charger outputs). To install: desolder the original relay, clean pads, insert this unit per silkscreen notch/orientation, solder all 5 pins, and inspect joints; observe coil polarity if the driver uses a diode or transistor; maintain creepage/clearance around high-voltage pins; typical board designators include “RL1/RLY1/953.” Compatible with control-board locations calling for a sealed 12 VDC 1 Form A 30 A relay of the HSINDA 953G footprint
Compatibility checklist (use to confirm fit) — Compatible with boards that specify 953-1A-12DG-2 or “953G 1A 12V sealed” and that use the 5-pin two-common-terminal footprint shown in the 953G outline. Match the following before purchase: coil 12 VDC (≈77 mA), contact form 1A (normally open), load ≤30 A at 250 VAC or ≤30 VDC (resistive), outline ~27.4 × 31.8 mm, engage height/clearance, and pick-up ≤9 V. If your original part is 953-1C (SPDT) or 953-1A-12DG-1 (4-pin), it is not a drop-in; choose the identical contact arrangement and pin count for your board. Compatible with the HSINDA 953G sealed footprint only.
Reliability & related items — Coil class options and sealed housing support harsh environments; operate time ≤15 ms, release ≤10 ms; dielectric strength test levels support robust isolation. For longevity on inductive loads, size margins conservatively and add suppression (e.g., flyback diode/TVS across coil or snubber across load if your board lacks it). Compatible with common control-board service materials (rosin flux, solder wick) and with maintenance practices such as conformal-coating rework where required. Operating range −40 °C to +85 °C; store dry and within temperature limits.
