Key Parameters

Substitute Part Grouping Explanation

Substitution for the M2022SS1W02 is determined by strict alignment of electrical and mechanical parameters. The primary substitution criteria are:

Electrical Parameters: Circuit configuration (DPDT), switch function (On-On), current ratings (minimum 6A AC / 4A DC), and voltage ratings (minimum 125V AC / 30V DC).

Mechanical Parameters: Panel mount configuration, standard round actuator, panel cutout dimensions (6.50mm circular), and bushing thread (1/4-40).

Termination Compatibility: The original part uses quick connect termination. Substitute parts may employ alternative termination styles (solder lug, PC pin) provided the electrical and mechanical interfaces remain compatible with the application circuit design.

Environmental & Compliance: Operating temperature range (-30°C to 85°C), RoHS3 compliance, and REACH unaffected status are maintained across all qualified substitutes.

The M2022SS1W01 (NKK Switches) is classified as a manufacturer-recommended substitute with identical electrical and mechanical specifications, differing only in termination style (solder lug vs. quick connect) and packaging format.

The 2M1-DP1-T1-B1-M2QE (Carling Technologies) is classified as a similar substitute with comparable electrical performance and mechanical compatibility, though with minor variations in current rating (5A AC/DC vs. 6A AC / 4A DC), voltage rating (28V DC vs. 30V DC), panel cutout diameter (6.35mm vs. 6.50mm), and enhanced electrical life (50,000 cycles vs. 25,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

M2022SS1W01 (NKK Switches): This part is the manufacturer-recommended substitute and maintains identical electrical and mechanical specifications to the M2022SS1W02. The primary difference is termination style (solder lug instead of quick connect). This substitute is appropriate for applications where solder lug termination is compatible with the circuit design. Both parts share obsolete product status and equivalent compliance certifications (ROHS3, REACH unaffected).

2M1-DP1-T1-B1-M2QE (Carling Technologies): This substitute is suitable for applications where the slightly reduced AC current rating (5A vs. 6A) and DC voltage rating (28V vs. 30V) remain within system operating margins. The part offers enhanced electrical life (50,000 cycles vs. 25,000 cycles) and IP67 ingress protection, making it advantageous for environments requiring moisture and dust resistance. The active product status ensures ongoing availability and supply chain continuity. Panel cutout diameter variation (6.35mm vs. 6.50mm) requires mechanical compatibility assessment for panel mounting.

Selection between these substitutes depends on termination requirements, environmental conditions, electrical margin requirements, and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the M2022SS1W01 be used as a direct replacement for the M2022SS1W02?

A: The M2022SS1W01 is electrically and mechanically equivalent with identical DPDT configuration, current ratings (6A AC / 4A DC), voltage ratings (125V AC / 30V DC), and panel mount specifications. The primary difference is termination style: M2022SS1W01 uses solder lug termination while M2022SS1W02 uses quick connect termination. Direct replacement is possible if the circuit design accommodates solder lug connections.

Q: What are the limitations of using the 2M1-DP1-T1-B1-M2QE as a substitute?

A: The 2M1-DP1-T1-B1-M2QE has a reduced AC current rating (5A vs. 6A) and DC voltage rating (28V vs. 30V). Applications operating at or near the original 6A AC or 30V DC specifications may exceed this substitute's ratings. Additionally, the panel cutout diameter is 6.35mm versus 6.50mm, requiring mechanical compatibility assessment for existing panel installations. Termination style is PC pin, requiring circuit design compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both M2022SS1W01 and 2M1-DP1-T1-B1-M2QE are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance equivalent to the original M2022SS1W02.

Q: What is the difference between quick connect and solder lug termination?

A: Quick connect termination (M2022SS1W02) uses a 0.062" (1.5mm) spade connector for push-on connection to circuit terminals. Solder lug termination (M2022SS1W01) requires soldering directly to circuit board pads or wire connections. Selection depends on circuit design and assembly process requirements.

Q: Does the 2M1-DP1-T1-B1-M2QE offer any performance advantages?

A: The 2M1-DP1-T1-B1-M2QE provides doubled electrical life (50,000 cycles vs. 25,000 cycles) and IP67 ingress protection (dust tight, waterproof), making it suitable for harsh or moisture-prone environments. However, it has reduced current and voltage ratings compared to the original part.

Q: What should be considered when selecting between these substitutes?

A: Primary considerations are: (1) termination style compatibility with circuit design, (2) electrical margin requirements relative to reduced ratings in the Carling Technologies part, (3) environmental conditions (IP67 protection availability), (4) panel cutout diameter compatibility, and (5) long-term supply chain availability (active vs. obsolete product status).
