RI-02SMD-G1 Equivalent & Substitute Parts

Part Overview

The RI-02SMD-G1 is a glass body reed switch manufactured by Comus International, configured as a single-pole single-throw normally open (SPST-NO) device. This surface mount component is rated for 500mA switching current at 140V AC and 200V DC, with a maximum power rating of 10W. The part operates within a 5–18AT (Ampere-Turn) range with response times of 0.3ms operation and 0.07ms release.

The RI-02SMD-G1 is classified as obsolete. Locating active production alternatives is necessary to ensure long-term component availability, supply chain continuity, and access to current manufacturing quality assurance and compliance certifications.

Substitute Part Grouping Explanation

The RI-02SMDM-1015-G1 qualifies as a functional substitute for the RI-02SMD-G1 based on the following electrical and mechanical parameters:

Electrical Equivalence:

Both parts maintain identical switching current capacity: 500mA (AC/DC)
Both parts maintain identical AC switching voltage: 140V
Both parts maintain identical DC switching voltage: 200V
Both parts maintain identical power rating: 10W
Both parts share identical circuit configuration: SPST-NO

Mechanical Equivalence:

Both parts use surface mount technology with gull wing termination
Both parts maintain compatible overall length: 0.639" (16.23mm)
Both parts maintain compatible height above board within acceptable tolerance
Both parts operate within overlapping temperature ranges

Key Difference: The RI-02SMDM-1015-G1 features a molded body construction (versus glass body) and operates within a narrower 10–15AT range compared to the 5–18AT range of the RI-02SMD-G1. This narrower operate range does not restrict substitution in applications where the magnetic field strength falls within 10–15AT.

Compliance Advantage: The RI-02SMDM-1015-G1 carries active product status with current RoHS3 compliance, ensuring ongoing manufacturing support and regulatory alignment.

Engineering Selection Recommendations

For Direct Substitution: The RI-02SMDM-1015-G1 is suitable as a direct substitute when the application magnetic field strength operates within the 10–15AT range. This part provides the advantage of active product status, ensuring ongoing availability and current manufacturing compliance certifications (ROHS3).

Compliance Considerations: The RI-02SMDM-1015-G1 meets ROHS3 compliance, which supersedes the RoHS compliance of the obsolete RI-02SMD-G1. Both parts maintain REACH Unaffected status and identical MSL ratings, supporting equivalent handling and storage requirements.

Temperature Range Consideration: The RI-02SMDM-1015-G1 operates from -40°C to 125°C, compared to the RI-02SMD-G1 range of -55°C to 125°C. Applications requiring operation below -40°C must evaluate alternative solutions.

Packaging and Availability: The RI-02SMDM-1015-G1 is available in Cut Tape and Digi-Reel packaging with significantly higher inventory levels (32,897 pcs), supporting production volume requirements and reducing lead times compared to the obsolete RI-02SMD-G1.

Frequently Asked Questions (FAQ)

Q: Can the RI-02SMDM-1015-G1 replace the RI-02SMD-G1 in all applications?

A: The RI-02SMDM-1015-G1 is functionally equivalent for applications where the magnetic field strength falls within 10–15AT. Applications requiring operation below -40°C or magnetic field strengths outside this range require alternative evaluation.

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

A: The RI-02SMD-G1 uses glass body construction with a 5–18AT operate range, while the RI-02SMDM-1015-G1 uses molded body construction with a narrower 10–15AT operate range. Both maintain identical electrical ratings (500mA, 140V AC, 200V DC, 10W).

Q: Why is the RI-02SMD-G1 classified as obsolete?

A: The RI-02SMD-G1 is no longer in active production. The RI-02SMDM-1015-G1 represents the current production equivalent from Comus International.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts share identical overall length (0.639" / 16.23mm) and compatible height above board measurements. Gull wing termination is identical on both parts, supporting direct PCB footprint compatibility.

Q: What packaging options are available for the substitute part?

A: The RI-02SMDM-1015-G1 is available in Cut Tape (CT) and Digi-Reel packaging, with inventory of 32,897 pcs supporting production requirements.

Q: Do both parts meet current regulatory compliance standards?

A: The RI-02SMDM-1015-G1 meets ROHS3 compliance and maintains REACH Unaffected status. Both parts carry MSL 1 (Unlimited) ratings, supporting equivalent handling and storage protocols.
