Equivalent & Substitute Parts for 7101SPYALE Toggle Switch SPDT

Part Overview

The 7101SPYALE is a toggle switch SPDT (Single Pole Double Throw) manufactured by C&K, designed for panel mount, right-angle applications. This part operates at 5A (AC/DC) with 120V AC and 28V DC ratings. The product is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SPYALE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Panel Mount, Right Angle)
• Termination style (PC Pin)
• Bushing thread specification (1/4-40)

Electrical Compatibility Criteria:

• Current rating must equal or exceed 5A (AC/DC)
• Voltage rating - AC must equal or exceed 120V
• Voltage rating - DC must equal or exceed 28V

Mechanical Compatibility Criteria:

• Panel cutout dimensions must accommodate 6.35mm circular opening
• Actuator length within acceptable tolerance for panel assembly

The substitute parts are grouped into two categories: direct manufacturer equivalents from C&K and functionally similar alternatives from Electroswitch that meet or exceed the electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

7101SPYARE (Direct C&K Equivalent): This is the primary substitute for the obsolete 7101SPYALE. It maintains identical electrical ratings (5A AC/DC, 120V AC, 28V DC), mechanical specifications, and actuator configuration. Both parts share the same base product number (7101SP) and feature identical panel cutout dimensions and bushing thread specifications. The 7101SPYARE is currently in active production status with 747 units in stock. RoHS compliance is maintained, though REACH status differs from the original part.

A123S1YAQP (Electroswitch Alternative): This substitute provides enhanced electrical performance with 6A current rating and 125V AC rating, exceeding the original 5A/120V specifications. It maintains the anti-rotation actuator type matching the 7101SPYALE and operates across an expanded temperature range (-30°C ~ 90°C). This part is actively produced with 1,078 units available. RoHS compliance is confirmed with MSL rating of 1 (Unlimited).

A123S1YAG and A123S1YAQ (Electroswitch Alternatives): These parts provide equivalent electrical performance (6A AC/DC, 125V AC, 28V DC) with panel mount, right-angle configuration and 1/4-40 bushing thread. Both are actively produced with high inventory availability. The primary distinction is actuator type: A123S1YAG features a standard round actuator, while A123S1YAQ also uses standard round configuration. Both operate across -30°C ~ 90°C with 60,000 cycle electrical life.

All substitute parts maintain PC Pin termination and epoxy sealed terminals consistent with the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 7101SPYARE directly replace the 7101SPYALE without any modifications?

A: Yes. The 7101SPYARE is a direct equivalent with identical electrical ratings (5A AC/DC, 120V AC, 28V DC), mechanical mounting specifications, panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator configuration (anti-rotation, 10.67mm length). Both parts use PC Pin termination and feature epoxy sealed terminals.

Q: What are the key differences between the C&K 7101SPYARE and the Electroswitch A123S1YAQP?

A: The 7101SPYARE maintains the original 5A current rating and 120V AC voltage rating. The A123S1YAQP provides higher electrical performance with 6A current rating and 125V AC rating. Both share the anti-rotation actuator type and operate across similar temperature ranges. The A123S1YAQP has a slightly shorter actuator length (10.41mm vs. 10.67mm) and lower electrical life rating (60,000 vs. 100,000 cycles).

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (7101SPYARE, A123S1YAG, A123S1YAQ, A123S1YAQP) are RoHS compliant. The original 7101SPYALE is ROHS3 compliant.

Q: What is the difference between the Electroswitch A123S1YAG and A123S1YAQ?

A: Both parts are electrically and mechanically identical with 6A AC/DC current rating, 125V AC voltage rating, and 1/4-40 bushing thread. The primary distinction is inventory availability: A123S1YAQ has 910 units in stock compared to 762 units for A123S1YAG. Both feature standard round actuators and operate across -30°C ~ 90°C.

Q: Does the slightly shorter actuator length of the Electroswitch parts (10.41mm vs. 10.67mm) affect compatibility?

A: Actuator length differences of 0.26mm are within typical mechanical tolerances for panel mount applications. However, panel assembly design should be reviewed to confirm the shorter actuator length is acceptable for the specific application.

Q: What is the electrical life difference between the C&K and Electroswitch substitutes?

A: The C&K 7101SPYALE and 7101SPYARE are rated for 100,000 electrical cycles. The Electroswitch alternatives (A123S1YAG, A123S1YAQ, A123S1YAQP) are rated for 60,000 electrical cycles. Application duty cycle requirements should be evaluated when selecting between these options.

Q: Are the panel cutout dimensions identical across all substitute parts?

A: The C&K parts (7101SPYALE and 7101SPYARE) specify circular panel cutout dimensions of 6.35mm diameter. The Electroswitch parts do not specify panel cutout dimensions in the provided data. Panel assembly compatibility should be confirmed during design integration.
