Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SW246A7 are qualified based on the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Current and voltage ratings must meet or exceed the application requirements
• RoHS3 compliance is required

Two substitute parts meet these criteria:

1. E201MD1AQE (C&K) - Exceeds current rating (7.5A AC/DC vs. 5A AC/4A DC), maintains 125V AC rating, and provides enhanced ingress protection (IP57).

2. 100AWDP1T1B4M6QE (E-Switch) - Meets current rating (5A AC/DC), maintains 120V AC rating, and provides enhanced ingress protection (IP67).

Parameter Comparison

Engineering Selection Recommendations

E201MD1AQE (C&K) is suitable for applications requiring higher current capacity (7.5A AC/DC) and enhanced environmental protection (IP57). This part maintains the same 125V AC rating and electrical life as the SW246A7. The actuator length is nearly identical (7.62mm vs. 7.50mm), minimizing mechanical redesign. Both parts are ROHS3 compliant and active products. Note that REACH status differs; E201MD1AQE is REACH Affected.

100AWDP1T1B4M6QE (E-Switch) is suitable for applications requiring the highest ingress protection (IP67) and extended operating temperature range (-30°C to 85°C). This part maintains the same 5A AC current rating as the SW246A7 and is ROHS3 compliant. The actuator length is longer (12.70mm vs. 7.50mm), which may require panel cutout verification. Electrical life is lower (30,000 cycles vs. 40,000 cycles).

Both substitute parts are active products with current inventory availability and maintain ROHS3 compliance for regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can E201MD1AQE replace SW246A7 in all applications?

A: E201MD1AQE is electrically compatible for applications rated at or below 5A AC / 4A DC, as it exceeds these ratings. Mechanical compatibility must be verified due to the 7.62mm actuator length (vs. 7.50mm). REACH compliance status differs and must be evaluated for your supply chain requirements.

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

A: E201MD1AQE provides higher current capacity (7.5A) and IP57 ingress protection with 40,000 electrical cycles. 100AWDP1T1B4M6QE provides the highest ingress protection (IP67) but with lower electrical life (30,000 cycles) and a longer actuator (12.70mm).

Q: Does actuator length affect substitution compatibility?

A: Yes. The SW246A7 has a 7.50mm actuator. E201MD1AQE (7.62mm) is nearly identical and typically compatible. 100AWDP1T1B4M6QE (12.70mm) is significantly longer and requires verification of panel cutout dimensions and mechanical clearance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SW246A7, E201MD1AQE, and 100AWDP1T1B4M6QE are all ROHS3 compliant. However, E201MD1AQE is REACH Affected, while SW246A7 and 100AWDP1T1B4M6QE are REACH Unaffected.

Q: Which substitute part has the longest operating temperature range?

A: Both E201MD1AQE and 100AWDP1T1B4M6QE operate from -30°C to 85°C, compared to SW246A7 which operates from -20°C to 85°C.

Q: Can 100AWDP1T1B4M6QE be used in applications requiring 40,000 electrical cycles?

A: No. 100AWDP1T1B4M6QE is rated for 30,000 electrical cycles, which is lower than the SW246A7 specification of 40,000 cycles. E201MD1AQE maintains the 40,000 cycle rating.
