T103MHCRE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The T103MHCRE is an active production toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. This panel mount component is rated for 2A at 120V AC and 28V DC, with a circular 4.95mm diameter panel cutout and 10-48 bushing thread. The switch employs PC pin termination with epoxy sealed terminals and operates across -30°C to 85°C. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T103MHCRE is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-Off-On
• Voltage Ratings: 120V AC and 28V DC minimum
• Mounting Interface: Panel mount with 4.95mm circular cutout and 10-48 bushing thread
• Termination: PC pin configuration
• Operating Temperature: -30°C to 85°C range
• Actuator Type: Standard round actuator
• Electrical Life: 30,000 cycles minimum

The substitute part 200MSP3T2B1M2QE from E-Switch meets all critical substitution criteria. While the current rating differs (3A versus 2A), the higher rating provides functional compatibility for applications designed for the 2A specification. Both parts share identical voltage ratings, panel cutout dimensions, bushing thread specifications, termination style, operating temperature range, and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the T103MHCRE and 200MSP3T2B1M2QE are active production components with ROHS3 compliance. The primary distinction is the current rating: the E-Switch substitute provides 3A capacity compared to the C&K original's 2A specification. For applications operating at or below 2A, the 200MSP3T2B1M2QE functions as a direct substitute with identical mechanical and electrical interface characteristics. The higher current rating of the substitute part does not degrade performance in lower-current applications. Both parts maintain equivalent voltage ratings, panel mounting geometry, termination configuration, and operating temperature specifications. Selection between these parts should be based on availability, lead time, and packaging requirements (Tray versus Bulk).

Frequently Asked Questions (FAQ)

Q: Can the 200MSP3T2B1M2QE replace the T103MHCRE in existing designs?

A: Yes. The substitute part maintains identical SPDT circuit configuration, On-Off-On switching function, voltage ratings (120V AC / 28V DC), panel cutout dimensions (4.95mm circular), bushing thread (10-48), PC pin termination, and operating temperature range (-30°C to 85°C). The 3A current rating of the substitute accommodates applications designed for 2A operation.

Q: What is the difference in actuator length between these parts?

A: The T103MHCRE actuator measures 5.44mm while the 200MSP3T2B1M2QE actuator measures 5.33mm. This 0.11mm difference is within typical mechanical tolerance for panel mount toggle switches and does not affect functional compatibility or panel interface geometry.

Q: Are there packaging differences between these substitute parts?

A: Yes. The T103MHCRE is supplied in Tray packaging, while the 200MSP3T2B1M2QE is supplied in Bulk packaging. Packaging selection should align with inventory management and assembly process requirements.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the T103MHCRE and 200MSP3T2B1M2QE are ROHS3 compliant and active production components. The T103MHCRE carries REACH Affected status while the 200MSP3T2B1M2QE is REACH Unaffected. Both are classified under ECCN EAR99 and HTSUS 8536.50.9065.

Q: What electrical life rating should be expected from these switches?

A: Both parts are rated for 30,000 electrical cycles, providing equivalent operational longevity across the specified voltage and current ranges.
