Substitute Part Grouping Explanation

Substitution of the LS3M2D is based on electrical and mechanical parameter equivalence within the HDLS series from Honeywell Sensing and Productivity Solutions. The substitute part must satisfy the following criteria:

Electrical Equivalence:

• Identical circuit configuration: DPDT (DB/DM)
• Identical switch function: Mom-Off-Mom
• Matching current ratings: 10A AC and 800mA DC
• Matching voltage ratings: 120V AC and 115V DC

Mechanical Equivalence:

• Identical actuator type: Side Rotary - No Lever
• Identical mounting type: Chassis Mount
• Identical termination style: Plug In
• Identical feature set: Center Neutral

Environmental & Compliance Equivalence:

• Operating temperature range: -1°C to 121°C
• RoHS Compliance status
• Moisture Sensitivity Level: 1 (Unlimited)

The LSM6D meets all substitution criteria and is classified as an active product within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

The LSM6D is a direct electrical and mechanical equivalent to the LS3M2D. Both components share identical electrical specifications, mechanical configurations, and environmental operating parameters within the HDLS series.

Selection Basis:

The LSM6D is classified as an active product, whereas the LS3M2D is obsolete. For new designs or ongoing production requiring DPDT Mom-Off-Mom snap action switches with 10A AC (120V) and 800mA DC (115V) ratings, the LSM6D provides continuity of supply and design compatibility.

Both components maintain RoHS compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The LSM6D is available in bulk packaging, supporting production requirements.

Frequently Asked Questions (FAQ)

Q: Can the LSM6D directly replace the LS3M2D in existing applications?

A: Yes. The LSM6D is electrically and mechanically equivalent to the LS3M2D. Both components feature identical circuit configuration (DPDT), switch function (Mom-Off-Mom), current ratings (10A AC, 800mA DC), voltage ratings (120V AC, 115V DC), actuator type (Side Rotary - No Lever), mounting type (Chassis Mount), and termination style (Plug In). No circuit modifications are required.

Q: What is the primary reason to substitute the LS3M2D?

A: The LS3M2D is classified as obsolete. The LSM6D is the active equivalent within the same HDLS series, ensuring ongoing availability and supply chain continuity.

Q: Are there any compliance differences between the LS3M2D and LSM6D?

A: No. Both components are RoHS compliant and share identical moisture sensitivity levels (MSL 1 - Unlimited). Both are classified under ECCN EAR99 for export control purposes.

Q: What packaging options are available for the LSM6D?

A: The LSM6D is available in bulk packaging. The LS3M2D was supplied with standard packaging. Confirm packaging requirements with procurement specifications.

Q: Are the operating temperature ranges identical?

A: Yes. Both the LS3M2D and LSM6D operate across the identical temperature range of -1°C to 121°C.

Q: What are the mechanical specifications that ensure substitution compatibility?

A: Substitution compatibility is ensured through identical pretravel (18°), differential travel (10°), overtravel (57°), and operating force (46gfm) specifications. Both components feature center neutral functionality.
