Description
Product Overview
The TMEIC ARND-3620 is an industrial printed circuit board identified in available parts records as an operator-control board associated with the LEOPACK-WI system. The alternate designation 2N3A3620-B is useful when checking maintenance records, equipment drawings, spare-parts lists, or an existing board label. This identification establishes the board’s general category, but it does not confirm its complete electrical design, connector assignments, firmware requirements, or compatibility with every system using related TMEIC hardware.
For maintenance teams supporting installed equipment, the primary concern is preserving the original control configuration. Before ordering a TMEIC ARND-3620, compare the complete part number and revision markings on the installed board with the replacement unit. Check connector positions, board layout, mounting details, and any system-specific identifiers. A visually similar PCB may belong to a different assembly or revision, and the available identification records do not provide enough evidence to approve an unconditional substitute.
The ARND-3620 is reported as discontinued, making inventory condition and test documentation important procurement considerations. A unit described as unused may have been stored for years, while a refurbished board may have undergone repair without necessarily having been tested in the customer’s actual equipment. Ask for clear photographs of the label and PCB, confirmation of the 2N3A3620-B cross-reference where applicable, and a written description of any inspection or functional testing performed. The TMEIC ARND-3620 should be treated as a legacy control component whose application fit must be confirmed against the installed system—not selected on model resemblance alone.
Product Introduction (Non-Templated)
A control-board failure can extend equipment downtime when the original assembly is no longer in regular production. The TMEIC ARND-3620 is identified as an operator-control PCB for LEOPACK-WI-related equipment, with 2N3A3620-B recorded as an alternate part number.
For maintenance or spare-parts planning, verify the installed board’s markings and equipment application before approving a replacement. No verified public datasheet was found to substantiate electrical ratings, connector pinouts, or firmware requirements for this exact model.

Frequently Asked Questions
Q1: What is the TMEIC used for?
Available product records describe it as an operator-control printed circuit board associated with LEOPACK-WI. The precise control functions and supported equipment configurations have not been confirmed by an authoritative datasheet.
Q2: Is the same part as 2N3A3620-B?
Records list 2N3A3620-B as an alternate part number for . Confirm both identifiers on the original board or equipment bill of materials before ordering.
Q3: Can I hot-swap this board?
Do not assume hot-swapping is supported. The available information does not establish whether the or its host system supports live removal and insertion. Follow the equipment’s shutdown and isolation procedure unless the applicable service documentation explicitly permits hot-swapping.
Q4: Does this support firmware v3.1?
A firmware version or compatibility matrix for was not verified. Confirm the host system, board revision, installed firmware, and approved upgrade path before installation.
Q5: Can replace another TMEIC control board?
Not on model similarity alone. Confirm the complete part number, revision, connectors, system role, and configuration. A board with a similar designation may perform a different function.
Q6: How can I verify the board’s condition and authenticity?
Request photographs of the actual PCB, manufacturer label, revision markings, connectors, and any serial or traceability labels. Ask for a written condition statement and test report. Packaging or a “never used” description alone does not prove functional condition.
Q7: What warranty applies to ?
Warranty coverage depends on the seller’s written terms and the unit’s condition. Confirm the warranty period, exclusions, return process, and whether testing or repair is covered before placing the order. Do not assume that a legacy component carries current factory warranty coverage.
Final procurement recommendation: Treat as a legacy TMEIC operator-control PCB. Confirm the / 2N3A3620-B identification, equipment application, revision, and test evidence before committing to a replacement.
