Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS4W01-CC is determined by the following critical parameters:

Primary Electrical Compatibility Criteria:

• Circuit configuration must be DPDT
• AC current rating must be minimum 6A
• AC voltage rating must be minimum 125V
• Switch function must be On-Mom
• Termination style must be Solder Lug

Secondary Mechanical Compatibility Criteria:

• Mounting type must be Panel Mount, Rear
• Panel cutout diameter must accommodate 6.50mm or smaller
• Actuator type must be compatible with standard panel installations

Compliance Requirements:

• RoHS3 compliance required for new designs
• MSL rating of 1 (Unlimited) preferred for storage flexibility

The substitute parts identified—MPA206R, MPE206R, and MBN25SS4W01-CC—meet the primary electrical criteria and mounting specifications. MPA206R and MPE206R are manufactured by TE Connectivity ALCOSWITCH Switches and maintain active product status. MBN25SS4W01-CC is an NKK Switches alternative with bushing mount configuration.

Parameter Comparison

Engineering Selection Recommendations

MPA206R and MPE206R (TE Connectivity ALCOSWITCH) are the primary recommended substitutes. Both parts maintain active product status, ensuring long-term availability and supply chain stability. These components exceed the electrical specifications of the original part with 4A DC current rating versus 3A, and deliver 50,000 electrical life cycles compared to 25,000. The 6.35mm panel cutout diameter is compatible with the original 6.50mm specification. MPE206R provides additional splash-proof ingress protection, suitable for applications requiring environmental resistance.

MBN25SS4W01-CC (NKK Switches) is an active NKK alternative maintaining manufacturer continuity. This part features bushing mount configuration rather than panel mount rear, requiring mechanical redesign consideration. Detailed electrical specifications are not provided for this option.

All substitute candidates maintain ROHS3 compliance and MSL 1 rating, meeting modern regulatory and storage requirements. Selection between MPA206R and MPE206R depends on environmental exposure requirements; MPE206R is specified for splash-proof applications.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061SS4W01-CC without circuit modification?

A: Yes. Both parts maintain identical DPDT circuit configuration, On-Mom switch function, 6A AC current rating, and 125V AC voltage rating. Solder lug termination and panel mount rear configuration are preserved. The 6.35mm panel cutout diameter is compatible with the original 6.50mm specification.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical ratings and mechanical mounting specifications. MPE206R includes splash-proof ingress protection; MPA206R does not specify ingress protection. Selection depends on environmental exposure in the application.

Q: Why is the operating temperature range narrower in the substitute parts?

A: MPA206R and MPE206R operate from -20°C to 80°C, compared to the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C must evaluate thermal performance requirements independently.

Q: Are the substitute parts RoHS compliant?

A: Yes. MPA206R, MPE206R, and MBN25SS4W01-CC are all ROHS3 compliant, meeting current regulatory requirements for new designs and production.

Q: What is the advantage of the higher electrical life rating in substitute parts?

A: MPA206R and MPE206R specify 50,000 electrical life cycles versus 25,000 in the original part. This extended rating provides greater operational margin in high-cycle applications.

Q: Is MBN25SS4W01-CC a suitable alternative?

A: MBN25SS4W01-CC is an active NKK product with DPDT On-Mom configuration. However, it features bushing mount rather than panel mount rear configuration, requiring mechanical redesign. Detailed electrical specifications are not provided for direct comparison.

Q: What panel cutout modifications are required for the substitute parts?

A: MPA206R and MPE206R require a 6.35mm circular cutout, compared to 6.50mm for the original part. Existing 6.50mm cutouts accommodate the smaller diameter without modification. Panels designed for 6.35mm cutouts are not compatible with the original 6.50mm specification.
