Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2061SS4W01 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: DPDT
• Switch function: On-Momentary
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• AC voltage rating: 125V minimum
• AC current rating: 6A minimum
• Actuator type: Plunger for Cap

Acceptable Parameter Variations:

• DC current rating may exceed 3A (higher ratings are acceptable)
• DC voltage rating may exceed 30V (higher ratings are acceptable)
• Panel cutout diameter tolerance: ±0.15mm from 6.50mm
• Operating temperature range may be narrower than -30°C to 85°C
• Electrical life may exceed 25,000 cycles
• Mechanical life specifications may vary

The substitute parts MPA206R, MPE206R, and MBN25SS4W01 meet these criteria within the allowed parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

MPA206R and MPE206R (TE Connectivity ALCOSWITCH): Both parts are active products with ROHS3 compliance and meet all critical electrical parameters. MPA206R and MPE206R provide equivalent AC/DC ratings with enhanced electrical life (50,000 cycles vs. 25,000 cycles). The panel cutout diameter is 6.35mm, requiring a 0.15mm reduction in panel opening. MPE206R includes splash proof ingress protection, offering additional environmental protection. Both parts are subject to REACH regulations, whereas the original MB2061SS4W01 is REACH unaffected.

MBN25SS4W01 (NKK Switches): This part is an active NKK Switches product with ROHS3 compliance and maintains manufacturer continuity. However, detailed electrical and mechanical specifications are not provided in the available data, limiting direct parameter verification. The mounting type is specified as bushing mount rather than panel mount rear, indicating a different installation configuration.

For applications requiring direct parameter equivalence with documented specifications, MPA206R or MPE206R are the primary recommendations. For applications prioritizing manufacturer continuity within the NKK Switches product line, MBN25SS4W01 requires specification verification before selection.

Frequently Asked Questions (FAQ)

Q: Can MPA206R or MPE206R directly replace MB2061SS4W01 in existing designs?

A: Both parts meet the critical electrical parameters (DPDT, 6A AC at 125V, On-Momentary function, solder lug termination). The panel cutout diameter differs by 0.15mm (6.35mm vs. 6.50mm), requiring panel modification or use of an adapter bushing. Operating temperature range is narrower (-20°C to 80°C vs. -30°C to 85°C), which may affect applications in extreme cold environments.

Q: What is the difference between MPA206R and MPE206R?

A: Both parts share identical electrical ratings and mechanical specifications. MPE206R includes splash proof ingress protection, making it suitable for applications with moisture exposure. MPA206R lacks specified ingress protection. Selection depends on environmental requirements.

Q: Why is the DC voltage rating lower on MPA206R and MPE206R?

A: MPA206R and MPE206R are rated at 28V DC compared to the original 30V DC rating. This 2V difference remains within acceptable design margins for most DC applications. Applications requiring operation above 28V DC should retain the original MB2061SS4W01 or verify compatibility with the substitute part's specifications.

Q: Is MBN25SS4W01 a suitable substitute?

A: MBN25SS4W01 is an active NKK Switches product, maintaining manufacturer continuity. However, complete electrical and mechanical specifications are not provided in the available documentation. The mounting type is specified as bushing mount rather than panel mount rear, indicating a different installation method. Specification verification is required before selection.

Q: What compliance considerations apply to these substitutes?

A: All substitute parts are ROHS3 compliant. MPA206R and MPE206R are subject to REACH regulations, whereas the original MB2061SS4W01 is REACH unaffected. Applications in REACH-restricted regions should confirm regulatory compliance with the substitute manufacturer.
