MB2065LD3W01-BA Equivalent & Substitute Parts

Part Overview

The MB2065LD3W01-BA is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) configuration with 6A AC and 3A DC current ratings. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The switch is designed for panel mount rear installation with IP67 ingress protection and epoxy sealed terminals, suitable for applications requiring dust-tight and waterproof operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2065LD3W01-BA is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• AC current rating: 6A minimum
• AC voltage rating: 125V minimum
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• DC current rating: Substitute parts rated 4A DC exceed the original 3A DC specification
• DC voltage rating: Substitute parts rated 28V DC are acceptable as they remain below the original 30V DC specification
• Operating temperature range: Substitute parts with -20°C to 80°C range represent a narrower specification window
• Panel cutout dimensions: Variations in circular diameter (6.35mm or 11.80mm) indicate mechanical compatibility considerations
• Ingress protection: Substitute parts may have reduced or unspecified ingress protection ratings
• Electrical life: Substitute parts rated at 50,000 cycles exceed the original 25,000 cycles specification

The three substitute parts (MPA106D, MPE106D, MPG106D) meet all mandatory matching parameters and are manufactured by TE Connectivity ALCOSWITCH Switches with active product status.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (MPA106D, MPE106D, MPG106D) maintain active product status with TE Connectivity ALCOSWITCH Switches, ensuring long-term availability and supply chain continuity compared to the obsolete MB2065LD3W01-BA. All substitutes are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements.

MPA106D Selection Criteria: This substitute provides equivalent electrical specifications with a 6.35mm panel cutout diameter. The unspecified ingress protection rating requires evaluation against application environmental requirements. Suitable for applications where the original IP67 specification is not critical.

MPE106D Selection Criteria: This substitute offers splash-proof ingress protection, providing enhanced environmental sealing compared to MPA106D. The 6.35mm panel cutout diameter matches MPA106D. Recommended for applications requiring improved moisture resistance while maintaining the original 6.50mm cutout compatibility through mechanical adaptation.

MPG106D Selection Criteria: This substitute features a larger 11.80mm panel cutout diameter, requiring panel modification for installation. The unspecified ingress protection rating applies. Selection is appropriate only when panel cutout diameter accommodation is feasible and environmental sealing requirements are not critical.

All substitutes exceed the original electrical life specification at 50,000 cycles versus 25,000 cycles, providing improved component longevity. DC current ratings of 4A exceed the original 3A specification, offering enhanced DC performance margin.

Frequently Asked Questions (FAQ)

Q: Can MPA106D, MPE106D, or MPG106D be used as direct replacements for MB2065LD3W01-BA?

A: All three parts meet the mandatory electrical and mechanical parameters: SPDT circuit, 6A AC rating, 125V AC rating, panel mount rear configuration, and solder lug termination. Direct substitution is electrically valid. Panel cutout diameter differences (6.35mm or 11.80mm versus 6.50mm) may require mechanical evaluation depending on panel design tolerances.

Q: What are the key differences between the three substitute options?

A: MPA106D and MPE106D share identical 6.35mm panel cutout dimensions. MPE106D provides splash-proof ingress protection, while MPA106D ingress protection is unspecified. MPG106D features a larger 11.80mm panel cutout diameter and unspecified ingress protection. All three provide superior electrical life (50,000 cycles) and DC current rating (4A) compared to the original part.

Q: Does the narrower operating temperature range (-20°C to 80°C) of substitute parts affect compatibility?

A: The substitute parts operate within -20°C to 80°C, compared to the original -30°C to 85°C range. Applications operating within the narrower temperature window are unaffected. Applications requiring operation below -20°C or above 80°C require alternative component selection.

Q: How does the panel cutout diameter difference impact installation?

A: The original MB2065LD3W01-BA requires a 6.50mm circular cutout. MPA106D and MPE106D require 6.35mm cutouts (0.15mm smaller), typically accommodated by standard panel tolerances. MPG106D requires an 11.80mm cutout, necessitating panel modification. Verify panel design specifications before selection.

Q: Are all substitute parts RoHS and REACH compliant?

A: All three substitute parts are ROHS3 compliant. MPA106D, MPE106D, and MPG106D are REACH affected, indicating regulatory notification requirements. The original MB2065LD3W01-BA is REACH unaffected. Compliance verification with applicable regional regulations is required for final design approval.

Q: What ingress protection level should be selected for moisture-sensitive applications?

A: The original MB2065LD3W01-BA provides IP67 (dust-tight, waterproof) protection. MPE106D offers splash-proof protection, suitable for applications with moderate moisture exposure. MPA106D and MPG106D have unspecified ingress protection ratings. Applications requiring IP67-equivalent sealing should prioritize MPE106D or conduct environmental testing for MPA106D and MPG106D alternatives.
