UM2315 Equivalent & Substitute Parts

Part Overview

The UM2315 is a glass body reed switch manufactured by Coto Technology, classified as SPST-NO (Single Pole Single Throw, Normally Open) with a switching capacity of 250mA at 175V. This component is suitable for applications requiring reliable electromagnetic switching in a compact surface-mount package. The product status is obsolete, making identification of compatible substitute parts essential for design continuity and procurement planning. Alternative parts must maintain equivalent electrical performance characteristics and physical compatibility with existing board designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UM2315 are identified based on the following critical electrical and mechanical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPST-NO
• Mounting type: Surface Mount with Gull Wing termination
• Operating temperature range: -40°C to 125°C
• Physical envelope compatibility: Length approximately 0.376" to 0.400", Height Above Board approximately 0.064" to 0.094"

Allowable Parameter Variations:

• Current switching capacity: minimum 250mA AC/DC
• Voltage switching (AC/DC): sufficient to handle application requirements up to 175V
• Power rating: minimum 5VA or 5W
• Compliance certifications: RoHS and REACH status

The CT05-1535-G1 qualifies as a substitute based on its SPST-NO configuration, surface-mount design, compatible operating temperature range, and superior switching specifications. While voltage rating is lower (100V AC / 140V DC), and body type differs (molded vs. glass), these variations are within acceptable substitution parameters for applications operating below the specified voltage thresholds.

Parameter Comparison

Engineering Selection Recommendations

The CT05-1535-G1 is the identified substitute for the obsolete UM2315. Both components are manufactured by Coto Technology and share identical SPST-NO circuit topology and surface-mount Gull Wing termination. The CT05-1535-G1 maintains RoHS and REACH compliance, with ROHS3 certification exceeding the original RoHS compliance level.

The primary engineering consideration is voltage rating. The UM2315 supports 175V operation (AC/DC), while CT05-1535-G1 supports 100V AC and 140V DC. Selection of CT05-1535-G1 is appropriate for applications operating within these voltage parameters. For applications requiring the full 175V switching capability, alternative substitute candidates must be evaluated.

The CT05-1535-G1 provides enhanced current switching capacity in DC mode (350mA vs. 250mA), offering improved performance headroom for compatible applications. Package dimensions are similar, supporting direct board-level replacement with minor layout adjustments if necessary.

Frequently Asked Questions (FAQ)

Q: Can the CT05-1535-G1 replace the UM2315 directly on my PCB? A: Direct mechanical replacement is possible due to compatible surface-mount Gull Wing termination and similar package dimensions (9.55mm vs. 10.16mm length, 2.40mm vs. 1.64mm height). Board layout verification is required to confirm clearance compatibility.

Q: What is the critical difference between these two parts? A: The voltage switching rating differs: UM2315 switches 175V (AC/DC), while CT05-1535-G1 switches 100V AC and 140V DC. Electrical design operating voltage must not exceed CT05-1535-G1 specifications. The UM2315 is glass body; CT05-1535-G1 is molded body, with no functional impact on switching performance.

Q: Are both parts RoHS compliant? A: Both parts meet RoHS requirements. The CT05-1535-G1 carries ROHS3 certification, which includes additional restricted substance limitations compared to the original RoHS compliance of UM2315.

Q: What is the packaging format for the CT05-1535-G1? A: The CT05-1535-G1 is supplied in Cut Tape (CT) and Digi-Reel format, suitable for automated assembly processes.

Q: Can I use CT05-1535-G1 in a 200V application? A: No. The CT05-1535-G1 has a maximum voltage rating of 100V AC and 140V DC. Use in applications exceeding these ratings will result in component failure.
