Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Electrical Compatibility: Current rating (AC/DC) and voltage rating (AC/DC) must meet or exceed the application requirements of the 5649AB (6A AC at 125V, 4A DC at 30V).

Mechanical Compatibility: Panel cutout diameter, bushing thread size (1/4-40), and actuator length must be compatible with existing panel installations.

Circuit Configuration: DPDT circuit with On-Off-On switching function is required for functional equivalence.

Termination Style: Solder lug termination is mandatory for PCB integration compatibility.

Compliance: ROHS3 compliance is required for regulatory alignment with the main part.

Substitute parts are grouped into two categories:

Category 1 - Direct Electrical Equivalents (6A AC / 4A DC rated): Parts matching the full electrical specification of the 5649AB, enabling one-to-one replacement without circuit redesign.

Category 2 - Functional Equivalents (5A AC/DC rated): Parts with reduced current ratings (5A AC/DC) that are electrically compatible for applications not requiring the full 6A AC specification. These parts maintain DPDT configuration, panel mount compatibility, and solder lug termination.

Engineering Selection Recommendations

Direct Electrical Equivalents (Preferred for One-to-One Replacement):

MTA206P (TE Connectivity ALCOSWITCH) is the primary direct equivalent. It matches the 5649AB in current rating (6A AC, 4A DC), voltage rating (125V AC), circuit configuration (DPDT), and termination style (solder lug). The part is active in production with ROHS3 compliance. Electrical life rating of 60,000 cycles exceeds the 5649AB specification. Panel cutout diameter of 6.40mm is within acceptable tolerance of the 6.50mm specification. Operating temperature range (-20°C to 80°C) is narrower than the 5649AB but suitable for most industrial applications.

Functional Equivalents (For Applications Not Requiring Full 6A AC Rating):

2M1-DP3-T1-B1-M1QE (Carling Technologies) is suitable for applications where 5A AC/DC current rating is acceptable. This part maintains 125V AC voltage rating matching the 5649AB, DPDT configuration, solder lug termination, and 50,000 cycle electrical life. Panel cutout diameter of 6.35mm requires panel modification. Operating temperature range (-30°C to 85°C) exceeds the 5649AB specification. Product is active with ROHS3 compliance.

100DP3T1B1M1QEH (E-Switch) provides 5A AC/DC rating with 120V AC voltage specification. Electrical life of 40,000 cycles is lower than the 5649AB. Panel cutout diameter of 6.35mm requires modification. Product is active with ROHS3 compliance.

Parts Not Recommended for New Designs:

M2023SD3W01 and M2023SS1W01 (NKK Switches) are marked as obsolete. Although electrical specifications match the 5649AB (6A AC, 125V AC), obsolete status indicates discontinued production and limited availability. Electrical life of 25,000 cycles is significantly lower than the 5649AB.

Frequently Asked Questions (FAQ)

Q: Can the MTA206P replace the 5649AB in all applications?

A: MTA206P is electrically equivalent with matching current and voltage ratings. Panel cutout diameter differs by 0.10mm (6.40mm vs 6.50mm), which is within standard mechanical tolerance. Operating temperature range is narrower (-20°C to 80°C vs -40°C to 85°C). Verify application temperature requirements before substitution.

Q: What is the difference between the 5649AB and the 5A-rated substitutes?

A: The 5649AB is rated for 6A AC and 4A DC. Substitutes rated at 5A AC/DC have lower current capacity. These are suitable only for applications where maximum current draw does not exceed 5A. Verify circuit current requirements before selection.

Q: Why do some substitutes have different panel cutout diameters?

A: Panel cutout diameter varies by manufacturer design. The 5649AB requires 6.50mm diameter; substitutes with 6.35mm diameter require panel modification or use of adapter bushings. Verify panel compatibility before installation.

Q: Are all listed substitutes ROHS3 compliant?

A: All active and obsolete parts listed are ROHS3 compliant. Compliance status is consistent across the substitute group.

Q: What is the significance of electrical life ratings?

A: Electrical life indicates the number of switching cycles before contact degradation. The 5649AB is rated for 50,000 cycles. MTA206P exceeds this at 60,000 cycles. Lower-rated substitutes (6,000 to 40,000 cycles) may require more frequent replacement in high-cycle applications.

Q: Can I use a 5A-rated substitute in a 6A application?

A: No. Using a 5A-rated part in a 6A application exceeds the component's electrical rating and creates risk of contact failure and fire hazard. Current rating must match or exceed application requirements.

Q: What packaging options are available?

A: The 5649AB is supplied in Tray packaging. Substitutes are available in Tray or Bulk packaging. Verify packaging requirements for your procurement and assembly processes.
