300AA00102A: Does Your Quote Cover the Coil or the Complete Valve?

Purchasing guide | 28 September 2026
The 300AA00102A product listing uses the description “solenoid valve coil,” while its photographs show an electrical section together with a covered projecting section and retaining hardware. Before comparing prices, ask exactly which of those items the quotation includes. The product name alone is not a packing list.
Separate three quotation lines
Ask the seller to distinguish the electrical coil, the plug or connector assembly, and the hydraulic valve or cartridge components. List seals and retaining hardware separately where the installation requires them. If a component is supplied only as a complete assembly, the quotation should state that rather than leaving separate serviceability implied.
A small price difference can reflect a different supplied scope. Compare equivalent itemised packages before drawing conclusions about value. Do not assume the connector shown fitted in a product photograph is included with a replacement coil.
Confirm the electrical specification in writing
Obtain a clear photograph of the installed coil marking and the offered replacement marking. Ask for the specified voltage, AC or DC supply, power or current rating, duty information and applicable connector details. No voltage or pin assignment is assigned to 300AA00102A in this guide because the available views are not sufficient evidence for those conclusions.
Danfoss coil documentation lists supply voltage, frequency and power consumption as separate selection fields. Those fields illustrate why a physically similar coil is not automatically equivalent. Danfoss's product-specific ratings are not transferred to this independently listed component.
| Option and inspection condition | Parts cost scope | Workshop time | Downtime and delivery considerations |
|---|---|---|---|
| Repair the supply or connector when testing identifies that fault and the coil/valve remain serviceable. | The diagnosed wiring or connector repair items. | Electrical diagnosis, repair and functional verification. | Avoid ordering a coil before the supply-side fault is resolved. |
| Coil-only replacement when the electrical fault is confirmed and separate replacement is supported. | Correct rated coil and required retention or connection items. | Specified replacement and verification of commanded function. | Check electrical data and separate serviceability before dispatch. |
| Complete valve assembly when diagnosis or the approved repair method requires it. | Identified valve package, coil, seals and connector as explicitly quoted. | Hydraulic isolation, replacement and prescribed system checks. | Include the complete repair scope and any required contamination investigation. |
Keep symptoms separate from the purchasing conclusion
A function that will not operate does not by itself distinguish an electrical command problem from a coil or hydraulic fault. Have the technician identify the failed item using the correct circuit diagram and service procedure. Do not apply an assumed voltage to an unidentified coil or use an improvised pin assignment.
For a quote, provide the full installed reference, machine serial number, coil and valve photographs, diagnostic conclusion and required package. Evaluate parts, diagnostic labour, installation work and confirmed lead time together. A complete assembly is not automatically the most economical choice, and a coil-only order is not automatically a complete repair.

Request a clearly scoped quotation
Send the identification details and inspection findings above to GUANGZHOU JIAJUE MACHINERY EQUIPMENT CO.,LTD, together with quantity and destination. Ask us to state the exact supplied components, supporting identification evidence and confirmed dispatch terms in the quotation.
These are purchasing checks, not a machine-specific repair procedure or a record of a completed customer repair. Product photographs show visible features; they do not establish internal condition, test performance or compatibility. Installation and testing should follow the applicable equipment service information.
