MB2065SD3W01 Equivalent & Substitute Parts

Part Overview

The MB2065SD3W01 is a pushbutton switch with SPDT (Single Pole Double Throw) configuration manufactured by NKK Switches. This component is rated for 6A at 125V AC and 3A at 30V DC, featuring a plunger actuator with solder lug termination and IP67 ingress protection. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance, repair, and redesign applications. Active equivalent models from TE Connectivity ALCOSWITCH Switches provide functional alternatives that maintain electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065SD3W01 is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration must be SPDT
• Switch function must be On-On
• AC current rating must be 6A minimum
• AC voltage rating must be 125V minimum
• Mounting type must be Panel Mount, Rear
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate 6.50mm or smaller

Allowable Variation Parameters:

• DC current rating may exceed 3A (higher ratings are acceptable)
• DC voltage rating may exceed 30V (higher ratings are acceptable)
• Operating temperature range may be narrower than -30°C to 85°C
• Ingress protection may exceed IP67 (higher protection ratings are acceptable)
• Mechanical and electrical life specifications may differ when not specified in the original part

The substitute parts MPA106D and MPE106D meet these criteria with the following considerations: both maintain 6A AC and 125V AC ratings, offer higher DC ratings (4A at 28V), feature identical SPDT On-On configuration and solder lug termination, and are currently in active production status.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106D and MPE106D are suitable substitutes for the obsolete MB2065SD3W01 based on electrical parameter alignment and active product status.

MPA106D Selection Criteria:

• Maintains all critical electrical parameters (6A AC, 125V AC, SPDT On-On)
• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) match the original part
• Panel cutout diameter of 6.35mm is smaller than the original 6.50mm, requiring panel modification or use of adapter hardware
• Operating temperature range of -20°C to 80°C is narrower than the original specification

MPE106D Selection Criteria:

• Maintains all critical electrical parameters (6A AC, 125V AC, SPDT On-On)
• Active product status ensures long-term availability and supply chain stability
• ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) match the original part
• Splash Proof ingress protection provides environmental protection comparable to the original IP67 rating
• Panel cutout diameter of 6.35mm is smaller than the original 6.50mm, requiring panel modification or use of adapter hardware
• Operating temperature range of -20°C to 80°C is narrower than the original specification
• Higher electrical life rating (50,000 cycles) exceeds the original specification

Frequently Asked Questions (FAQ)

Q: Can MPA106D and MPE106D be used interchangeably with MB2065SD3W01?

A: Both parts meet the core electrical requirements (6A AC, 125V AC, SPDT On-On configuration). The primary consideration is panel cutout diameter: the substitute parts require a 6.35mm diameter hole versus the original 6.50mm. Panel modification or adapter hardware may be necessary. Operating temperature range is narrower (-20°C to 80°C versus -30°C to 85°C), which must be evaluated against application requirements.

Q: What is the difference between MPA106D and MPE106D?

A: Both parts share identical electrical ratings and mounting specifications. The primary difference is ingress protection: MPE106D provides Splash Proof protection, while MPA106D does not specify ingress protection. MPE106D is the preferred choice for applications requiring environmental protection.

Q: Are there any compliance or certification differences?

A: All three parts (MB2065SD3W01, MPA106D, and MPE106D) are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). The substitute parts are affected by REACH regulations, while the original part is REACH unaffected. This distinction must be evaluated for regulatory compliance in the target application region.

Q: What panel modifications are required for substitution?

A: The substitute parts (MPA106D and MPE106D) have a panel cutout diameter of 6.35mm compared to the original 6.50mm. Existing panel holes may require enlargement, or adapter hardware may be used to accommodate the smaller diameter.

Q: Do the substitute parts have longer electrical life?

A: Yes. Both MPA106D and MPE106D are rated for 50,000 electrical cycles, compared to 25,000 cycles for the original MB2065SD3W01. This represents a 2x improvement in electrical life specification.
