RI-02SMD-G2 Equivalent & Substitute Parts

Part Overview

The RI-02SMD-G2 is a glass body reed switch manufactured by Comus International, configured as a single-pole single-throw normally open (SPST-NO) device. This component operates at 500mA with a switching voltage of 140V AC and 200V DC, rated for 10W power dissipation. The part features surface mount gull wing termination and operates across a temperature range of -55°C to 125°C.

The RI-02SMD-G2 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this reed switch specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RI-02SMD-G2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Current rating: 500mA (AC/DC)
• Voltage switching capability: 140V AC / 200V DC minimum
• Power rating: 10W
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance status

Allowable Variations:

• Operate range and release range specifications may differ within functional limits
• Physical dimensions (length, body size, height above board) may vary due to different construction methods (glass vs. molded body)
• Operating temperature range may be narrower in substitute parts
• Product status may transition from obsolete to active

The RI-02SMDM-1015-G1 meets all mandatory matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The RI-02SMDM-1015-G1 is qualified as a direct substitute for the RI-02SMD-G2 based on electrical and mechanical parameter equivalence. Both components share identical switching current (500mA AC/DC), voltage ratings (140V AC / 200V DC), and power dissipation (10W). Both maintain surface mount gull wing termination and unlimited moisture sensitivity classification.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain support. Both components maintain full RoHS and REACH compliance, with the substitute achieving ROHS3 certification.

The operating temperature range of the substitute part (−40°C to 125°C) is narrower than the main part (−55°C to 125°C). Applications requiring operation below −40°C must retain the original RI-02SMD-G2 specification or identify alternative solutions.

The operate range specification differs: the main part specifies 5–18AT while the substitute specifies 10–15AT. Both release ranges overlap sufficiently (2–17AT vs. 2–13AT) to maintain functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the RI-02SMDM-1015-G1 be used as a direct replacement for RI-02SMD-G2 in all applications?

A: The RI-02SMDM-1015-G1 qualifies as a direct substitute for applications operating within −40°C to 125°C and with operate range requirements between 10–15AT. Applications requiring operation below −40°C or with operate range specifications below 10AT require design review.

Q: What is the primary difference between these two parts?

A: The main part features a glass body reed switch construction, while the substitute uses molded body construction. Both deliver identical electrical performance (500mA, 140V AC / 200V DC, 10W). The substitute part is currently in active production status, whereas the main part is obsolete.

Q: Are there packaging differences between these parts?

A: The RI-02SMD-G2 is specified with standard surface mount packaging. The RI-02SMDM-1015-G1 is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement and assembly workflows.

Q: Do both parts meet current regulatory requirements?

A: Both components are RoHS compliant and REACH unaffected. The substitute part carries ROHS3 certification, representing the current regulatory standard. Both maintain unlimited moisture sensitivity classification (MSL 1).

Q: What should be verified before implementing the substitute part?

A: Confirm that the application's minimum operating temperature requirement does not fall below −40°C. Verify that the operate range specification (10–15AT for the substitute) aligns with the magnetic field strength available in the application circuit.
