RI-60SMDM-1015-G1 Equivalent & Substitute Parts

Part Overview

The RI-60SMDM-1015-G1 is a molded body reed switch manufactured by Comus International, configured as a SPST-NO (Single Pole Single Throw - Normally Open) surface mount component. This switch is designed for applications requiring low-power switching with a rated capacity of 500mA at 140V AC and 200V DC, with a power rating of 10W. The component is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, inventory constraints, or when specific performance characteristics of alternative manufacturers better align with application parameters while maintaining functional compatibility within the defined electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RI-60SMDM-1015-G1 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPST-NO
• Operate range must be 10 ~ 15AT
• Switching voltage must support minimum 140V AC and 200V DC
• Switching current must support minimum 500mA AC/DC operation
• Rated power must be minimum 10W

Mechanical Compatibility Requirements:

• Mounting type must be Surface Mount
• Termination style must be Gull Wing
• Overall length tolerance within component footprint specifications
• Body dimensions compatible with PCB layout constraints

Environmental & Compliance Requirements:

• Operating temperature range must encompass -40°C ~ 125°C
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The substitute part 59170-1-S-00-D from Littelfuse Inc. meets all critical electrical, mechanical, and compliance parameters, with the exception of AC switching current specification (350mA AC versus 500mA AC/DC on the main part). However, the substitute part supports 500mA DC switching current and maintains all other functional requirements within acceptable parameters for SPST-NO reed switch applications.

Engineering Selection Recommendations

Primary Part Selection (RI-60SMDM-1015-G1): The RI-60SMDM-1015-G1 is the specified component and remains the first choice for new designs. This part is active in production with full inventory availability (1011 pcs in stock), RoHS3 compliance, and REACH unaffected status. The component meets all electrical and mechanical requirements with symmetric AC/DC current handling at 500mA.

Substitute Part Selection (59170-1-S-00-D): The 59170-1-S-00-D from Littelfuse Inc. is a qualified substitute for applications where the primary part is unavailable or where alternative sourcing is required. This substitute maintains electrical compatibility for DC switching applications at 500mA and AC switching at 350mA. The substitute part carries identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating. Littelfuse inventory availability is significantly higher (30400 pcs in stock), providing supply chain advantages. The substitute part exhibits improved DC current carry capacity (800mA versus 500mA) and slightly reduced height above board (2.41mm versus 2.72mm), which may provide layout benefits in space-constrained applications.

Compliance Verification: Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. Both components are classified under ECCN EAR99 with identical HTSUS coding (8536.50.9065).

Frequently Asked Questions (FAQ)

Q: Can the 59170-1-S-00-D directly replace the RI-60SMDM-1015-G1 in all applications?

A: The 59170-1-S-00-D is compatible with applications operating at 500mA DC switching current. For applications requiring 500mA AC switching current, the substitute part is rated at 350mA AC and must be evaluated against specific application requirements. Both parts maintain identical voltage ratings (140V AC, 200V DC), power rating (10W), and operating temperature range (-40°C ~ 125°C).

Q: What are the packaging differences between these parts?

A: The RI-60SMDM-1015-G1 is supplied in Tape & Reel (TR) packaging. The 59170-1-S-00-D is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both packaging formats are suitable for automated assembly processes, with selection dependent on production line equipment compatibility and volume requirements.

Q: Are there dimensional differences that affect PCB layout?

A: Both parts have nearly identical body dimensions (0.452" L x 0.090" W x 0.090" H versus 0.450" L x 0.090" W x 0.090" H) and overall length (0.639" versus 0.640"). The substitute part has a lower height above board (0.095" versus 0.107"), which may provide advantages in applications with height constraints. These dimensional variations are within standard PCB footprint tolerances for surface mount gull wing termination components.

Q: Do both parts meet the same regulatory requirements?

A: Both the RI-60SMDM-1015-G1 and 59170-1-S-00-D are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling.

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

A: The main electrical difference is AC switching current specification. The RI-60SMDM-1015-G1 is rated for 500mA AC/DC switching current, while the 59170-1-S-00-D is rated for 350mA AC and 500mA DC switching current. Both parts maintain identical voltage ratings and power ratings. The substitute part provides higher DC current carry capacity (800mA versus 500mA).

Q: Which part should be selected for new designs?

A: The RI-60SMDM-1015-G1 is the specified component and should be used for new designs. The 59170-1-S-00-D is identified as a substitute for situations where the primary part is unavailable or where alternative sourcing provides supply chain or cost advantages.
