MB2061SS1W01 Equivalent & Substitute Parts

Part Overview

The MB2061SS1W01 is a DPDT pushbutton switch manufactured by NKK Switches, designed for panel mount rear installation with 6A AC and 3A DC current ratings at 125V AC and 30V DC respectively. This component features a plunger actuator with solder lug termination and epoxy sealed terminals, rated for 100,000 mechanical cycles and 25,000 electrical cycles. The product is currently obsolete, making equivalent substitute parts necessary for ongoing maintenance, repair, and new design implementations where this switch specification remains applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS1W01 is determined by the following critical parameters: DPDT circuit configuration, On-Momentary switch function, panel mount rear installation capability, solder lug termination, and compatible electrical ratings. The primary substitutes are grouped as follows:

MFR Recommended Substitute - MBN25SS1W01 (NKK Switches): This part maintains identical circuit configuration (DPDT), switch function (On-Momentary), mounting type (Panel Mount, Rear), termination style (Solder Lug), and panel cutout diameter (6.50mm). The key difference is reduced current rating (3A AC versus 6A AC) and lower mechanical life (50,000 cycles versus 100,000 cycles). This substitute is suitable for applications where the lower current and cycle ratings are acceptable. Product status is Active.

Similar Substitutes - MPA206R and MPE206R (TE Connectivity ALCOSWITCH Switches): Both parts maintain DPDT configuration, On-Momentary function, panel mount rear installation, solder lug termination, and equivalent AC voltage rating (125V). These parts provide 6A AC current rating matching the original specification. Panel cutout diameter is 6.35mm (versus 6.50mm original), requiring panel modification. Both are Active products with higher electrical life ratings (50,000 cycles). MPE206R includes splash proof ingress protection. DC voltage rating is 28V (versus 30V original).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): MBN25SS1W01 is the manufacturer-recommended substitute from NKK Switches. It maintains identical mechanical interface (6.50mm panel cutout), mounting configuration, and termination style. This part is suitable for applications where current requirements do not exceed 3A AC. The Active product status ensures ongoing availability and supply chain continuity.

For Full Electrical Specification Match: MPA206R and MPE206R both provide 6A AC current rating matching the original specification. These parts require panel cutout modification from 6.50mm to 6.35mm. Both are Active products with extended electrical life (50,000 cycles). MPE206R provides additional splash proof ingress protection for applications requiring environmental resistance. DC voltage rating is 28V, which is acceptable for most applications requiring 30V DC or lower.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. MPA206R and MPE206R are REACH Affected, whereas the original part is REACH Unaffected. MBN25SS1W01 has Not Applicable REACH status.

Frequently Asked Questions (FAQ)

Q: Can MBN25SS1W01 replace MB2061SS1W01 in all applications? A: MBN25SS1W01 is suitable for applications where AC current does not exceed 3A. If your application requires 6A AC current, this substitute is not appropriate. The mechanical interface is identical (6.50mm panel cutout), eliminating installation modifications.

Q: What is the primary difference between MPA206R and MPE206R? A: Both parts share identical electrical specifications (6A AC, 4A DC, 125V AC, 28V DC) and mechanical configuration. MPE206R includes splash proof ingress protection, making it suitable for applications with moisture or environmental exposure. MPA206R lacks this protection feature.

Q: Do MPA206R and MPE206R require panel modifications? A: Yes. Both parts have a 6.35mm panel cutout diameter compared to the original 6.50mm specification. Panel drilling or cutout modification is required for installation.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts (MBN25SS1W01, MPA206R, and MPE206R) are ROHS3 compliant, matching the original MB2061SS1W01 compliance status.

Q: What is the electrical life difference between the original and substitutes? A: MB2061SS1W01 has 25,000 electrical cycles. MBN25SS1W01 maintains this rating. MPA206R and MPE206R provide extended electrical life at 50,000 cycles, offering improved longevity for high-cycle applications.

Q: Can I use MPA206R or MPE206R if my application requires 30V DC? A: MPA206R and MPE206R are rated for 28V DC maximum. For applications strictly requiring 30V DC operation, these substitutes are not suitable. MBN25SS1W01 does not specify DC voltage rating and should be verified with the manufacturer for 30V DC applications.

Q: What is the operating temperature range difference? A: MB2061SS1W01 and MBN25SS1W01 operate from -30°C to 85°C. MPA206R and MPE206R operate from -20°C to 80°C. For applications requiring operation below -20°C or above 80°C, the original or MBN25SS1W01 are required.
