Equivalent & Substitute Parts for 7103SPDA3ME

Part Overview

The 7103SPDA3ME is a toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuitry with On-Off-On switching function. This component is rated for 5A at 120V AC and 28V DC, designed for panel mount applications with right-angle orientation. The part is currently classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design requirements and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7103SPDA3ME is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Mounting type (Panel Mount, Right Angle)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)

Electrical Performance Criteria:

• Current rating must meet or exceed 5A (AC/DC)
• Voltage rating must meet or exceed 120V AC and 28V DC
• Electrical life must meet or exceed 40,000 cycles

Compliance Criteria:

• RoHS compliance status
• REACH compliance status

Two substitute parts have been identified based on these parameters:

1. 7103SPDA3SE (C&K) - Direct manufacturer equivalent with identical mechanical and electrical specifications but active product status
2. 34ASP31B5M6RT (Grayhill Inc.) - Similar configuration with reduced electrical ratings requiring application-level verification

Parameter Comparison

Engineering Selection Recommendations

7103SPDA3SE (Recommended Primary Substitute)

The 7103SPDA3SE is the direct equivalent replacement for the obsolete 7103SPDA3ME. Both components share identical electrical ratings (5A at 120V AC / 28V DC), mechanical specifications (panel mount, right-angle, 6.35mm circular cutout, 1/4-40 bushing thread), and functional characteristics (SPDT, On-Off-On). The 7103SPDA3SE maintains active product status with current manufacturing availability. RoHS compliance is confirmed for both parts. The primary distinction is REACH status: the 7103SPDA3SE is REACH Affected, whereas the original part is REACH Unaffected. This difference requires evaluation within the context of end-use application and regulatory requirements.

34ASP31B5M6RT (Limited Compatibility Substitute)

The 34ASP31B5M6RT from Grayhill Inc. provides mechanical and functional compatibility with identical panel mount configuration, cutout dimensions, and bushing thread specification. However, this component exhibits reduced electrical performance: current rating of 0.4VA and voltage ratings of 20V AC/DC, compared to the 5A and 120V AC / 28V DC specifications of the main part. This substitute is suitable only for applications where the reduced electrical ratings are compatible with circuit requirements. Actuator type differs (Standard Round versus Anti-Rotation), and actuator length is reduced (10.41mm versus 12.45mm), which may affect panel aesthetics and operational feel. Both parts maintain ROHS3 compliance and REACH Unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the 7103SPDA3SE be used as a direct replacement for the 7103SPDA3ME?

A: Yes. The 7103SPDA3SE is electrically and mechanically identical to the 7103SPDA3ME. Both components feature 5A current rating at 120V AC and 28V DC, identical panel mount configuration with 6.35mm circular cutout and 1/4-40 bushing thread, and matching SPDT On-Off-On switching function. The primary consideration is REACH compliance status, which differs between the two parts.

Q: What are the limitations of the 34ASP31B5M6RT as a substitute?

A: The 34ASP31B5M6RT has significantly reduced electrical ratings: 0.4VA current capacity and 20V maximum voltage (both AC and DC), compared to 5A and 120V AC / 28V DC for the original part. This substitute is applicable only to low-power applications within these reduced electrical parameters. Additionally, the actuator type is Standard Round rather than Anti-Rotation, and the actuator length is 10.41mm instead of 12.45mm.

Q: Are there mechanical compatibility concerns when substituting these parts?

A: All three components share identical panel mount specifications: right-angle orientation, 6.35mm circular panel cutout, and 1/4-40 bushing thread. Mechanical compatibility is confirmed for direct panel installation. The 34ASP31B5M6RT differs in actuator type and length, which may affect user interface characteristics but does not prevent physical installation.

Q: What is the significance of REACH compliance differences?

A: The 7103SPDA3ME is REACH Unaffected, while the 7103SPDA3SE is REACH Affected. This distinction indicates different regulatory substance restrictions applicable to each component. Applications subject to REACH regulations must evaluate whether the REACH Affected status of the 7103SPDA3SE is acceptable for the intended end-use.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 7103SPDA3ME and 34ASP31B5M6RT are ROHS3 Compliant. The 7103SPDA3SE is RoHS Compliant. All three components meet RoHS requirements.

Q: What is the electrical life specification for these components?

A: All three components are rated for 40,000 electrical cycles, indicating identical operational durability under specified switching conditions.
