Substitute Part Grouping Explanation

The CT05-3050-G1 (Coto Technology CT05 series) is identified as a functional substitute for the UM2376 based on the following critical parameters that define substitution compatibility:

Matching Parameters:

• Circuit Configuration: Both are SPST-NO devices
• Manufacturer: Both manufactured by Coto Technology
• Mounting Type: Both are Surface Mount with Gull Wing termination
• Operating Temperature Range: Both operate across -40°C ~ 125°C
• Current Switching Capability: Both rated for 250mA AC switching
• RoHS and Environmental Compliance: Both RoHS Compliant, REACH Unaffected

Functional Differences: The CT05-3050-G1 employs a Molded Body Reed construction compared to the Glass Body design of the UM2376. The substitute part supports higher DC current switching (350mA DC versus 250mA) and an increased power rating (5W versus 5VA). The operate range differs at 30 ~ 50AT versus the original 10 ~ 30AT, and the AC switching voltage is rated at 100V compared to 175V.

The CT05-3050-G1 is an Active product, ensuring continued availability and supply chain support for applications requiring this functional class of surface mount reed switch.

Parameter Comparison

Engineering Selection Recommendations

The UM2376 is classified as Obsolete. The CT05-3050-G1 (Coto Technology CT05 series) is the identified substitute, carrying Active product status and ROHS3 Compliant certification, ensuring long-term availability and environmental compliance. Both components maintain RoHS compliance and REACH unaffected status, supporting continued use in regulated applications.

Selection of the CT05-3050-G1 for new designs or replacements is supported by identical circuit configuration (SPST-NO), matching termination style (Gull Wing), surface mount capability, and overlapping AC current ratings. The substitute provides equivalent AC switching performance at 250mA with identical operating temperature range (-40°C ~ 125°C).

Design applications with AC switching requirements at 250mA and 100V AC are directly compatible. Applications operating at the original 175V AC level will require verification of system voltage compatibility with the 100V AC rating of the substitute. Similarly, applications requiring DC switching above 250mA benefit from the CT05-3050-G1's enhanced 350mA DC capability.

Frequently Asked Questions (FAQ)

Q: Can the CT05-3050-G1 directly replace the UM2376 in existing assemblies? A: The CT05-3050-G1 shares identical circuit configuration (SPST-NO), termination style (Gull Wing), and surface mount footprint. Direct substitution is mechanically and electrically feasible for applications where the 100V AC and 140V DC ratings are sufficient. Applications originally designed for 175V operation require system voltage evaluation.

Q: What is the primary difference between the UM2376 and CT05-3050-G1? A: The UM2376 uses Glass Body Reed construction, while the CT05-3050-G1 employs Molded Body Reed construction. The substitute part offers higher DC current capacity (350mA DC versus 250mA) and operates at lower maximum voltages (100V AC / 140V DC versus 175V AC/DC).

Q: Why is the UM2376 listed as Obsolete? A: The UM2376 is a legacy component in the UM2 series. Coto Technology's CT05 series Molded Body Reed switches represent the current active alternative, offering improved performance characteristics and continued manufacturing support.

Q: Are both parts RoHS compliant? A: Yes. The UM2376 is RoHS Compliant, and the CT05-3050-G1 is ROHS3 Compliant. Both meet current environmental standards and are REACH Unaffected.

Q: What is the packaging difference between these parts? A: The UM2376 packaging specification is not provided in the technical data. The CT05-3050-G1 is available in Tape & Reel (TR) packaging for automated assembly.

Q: Can the CT05-3050-G1 handle the same operate range as the UM2376? A: The UM2376 operates at 10 ~ 30AT, while the CT05-3050-G1 operates at 30 ~ 50AT. The substitute requires a higher magnetic field strength for activation but retains functional reed switch operation within its specified range.
