UM2325 Equivalent & Substitute Parts

Part Overview

The UM2325 is a Glass Body Reed Switch manufactured by Coto Technology, configured as a SPST-NO (Single Pole, Single Throw, Normally Open) device rated for 250mA at 175V with a 5VA power rating. The product is currently obsolete, necessitating identification of compatible alternatives for ongoing system support and new design implementations. Substitutes must maintain functional equivalence in switching characteristics and electrical performance while accommodating physical and environmental constraints.

Substitute Part Grouping Explanation

The CT05-3050-J1 serves as a direct substitute based on the following alignment criteria:

Common Functional Parameters:

• Circuit configuration: Both SPST-NO
• Switching current: Both rated 250mA (AC), with CT05-3050-J1 supporting 350mA DC
• Mounting type: Both Surface Mount
• Operating temperature range: Both -40°C ~ 125°C
• Moisture sensitivity: Both MSL 1 (Unlimited)
• Compliance: Both RoHS compliant and REACH unaffected

Electrical Performance Trade-offs: The CT05-3050-J1 operates at reduced maximum switching voltage (100V AC / 140V DC) compared to the UM2325 (175V AC/DC), but delivers higher power handling (5W vs 5VA) and increased current carry capability. The operate range differs (30 ~ 50AT vs 15 ~ 20AT), reflecting the molded body construction's higher magnetic sensitivity.

Parameter Comparison

Engineering Selection Recommendations

The CT05-3050-J1 is available with active product status and current inventory, addressing the obsolescence of the UM2325. Both components meet RoHS compliance and possess identical moisture sensitivity levels, supporting deployment in standard manufacturing and storage environments.

Selection of CT05-3050-J1 requires confirmation that application voltage requirements do not exceed 100V AC or 140V DC, as these represent the primary electrical constraint relative to the original UM2325 specification. The molded body construction and J-lead termination differ from the UM2325 glass body with gull-wing leads, necessitating PCB layout evaluation for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: What makes CT05-3050-J1 a direct substitute for UM2325? Both components share SPST-NO circuit configuration, 250mA AC switching current, identical operating temperature range (-40°C to 125°C), and equivalent moisture sensitivity classification (MSL 1). Both are surface-mounted devices from the same manufacturer with compatible compliance profiles.

Q: What are the limitations when substituting CT05-3050-J1 for UM2325? The CT05-3050-J1 operates at reduced switching voltages: 100V AC and 140V DC versus 175V for the UM2325. Applications requiring voltages above these thresholds cannot use this substitute. Additionally, the molded body and J-lead termination differ physically from the glass body with gull-wing leads.

Q: Are there packaging differences between these parts? The UM2325 is specified with standard packaging, while CT05-3050-J1 is supplied in Tape & Reel (TR) format. This affects bulk ordering and automated assembly processes.

Q: Do both parts meet industry compliance requirements? Both are RoHS compliant and REACH unaffected. The CT05-3050-J1 carries ROHS3 certification, providing updated compliance verification.

Q: What voltage range should I verify for CT05-3050-J1 substitution? Confirm that your application operates at or below 100V AC or 140V DC. If higher voltages are present in the circuit, CT05-3050-J1 is not suitable.

Q: How do the switching characteristics differ? The CT05-3050-J1 has a higher operate range (30 ~ 50AT) than the UM2325 (15 ~ 20AT), indicating greater magnetic sensitivity. This affects the magnetic field strength required for actuation.
