Honeywell LSM6D4 Equivalent & Substitute Parts Reference

Part Overview

The Honeywell LSM6D4 is a snap action DPDT (double pole double throw) switch with a side rotary actuator, rated for 10A AC at 120V and 800mA DC at 115V. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and system maintenance. The LSM6D4 features a chassis mount configuration with plug-in termination and center neutral functionality, making it suitable for applications requiring momentary-off-momentary switching action.

Due to its obsolete status, the LSM6D4 requires substitution with active production equivalents that maintain identical electrical and mechanical specifications to ensure seamless integration into existing designs without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSM6D4 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (DPDT), switch function (Mom-Off-Mom), current ratings (10A AC / 800mA DC), and voltage ratings (120V AC / 115V DC) must be identical.

Mechanical Parameters: Actuator type (Side Rotary - No Lever), mounting configuration (Chassis Mount), termination style (Plug In), operating force (46gfm), and travel specifications (18° pretravel, 10° differential travel, 57° overtravel) must match exactly.

Environmental & Compliance: Operating temperature range (-1°C to 121°C), RoHS compliance status, and moisture sensitivity level (MSL 1) must be maintained.

The LSM6D series represents the active production line for this switch family. Substitution within this series ensures full compatibility without design modification.

Engineering Selection Recommendations

The LSM6D represents the direct active production equivalent for the obsolete LSM6D4. All electrical, mechanical, and environmental parameters are identical, establishing full functional interchangeability.

Product Status Consideration: The LSM6D maintains active production status with confirmed inventory availability (664 pcs), ensuring reliable procurement for new designs and replacement applications. The LSM6D4 is classified as obsolete, making it unsuitable for new procurement.

Compliance & Certification: Both parts maintain RoHS compliance and MSL 1 rating, satisfying regulatory requirements for industrial and commercial applications. The LSM6D carries REACH Unaffected status, providing additional compliance assurance.

Packaging Consideration: The LSM6D is supplied in bulk packaging, whereas the LSM6D4 packaging specification is not provided. Bulk packaging is standard for industrial switch procurement and does not affect functional performance or circuit integration.

The LSM6D is the appropriate selection for all applications currently specified for the LSM6D4.

Frequently Asked Questions (FAQ)

Q: Can the LSM6D directly replace the LSM6D4 without circuit modification?

A: Yes. The LSM6D is electrically and mechanically identical to the LSM6D4 across all specified parameters. No circuit modification is required. The parts are pin-compatible and functionally equivalent.

Q: What is the primary reason for substituting the LSM6D4?

A: The LSM6D4 is classified as obsolete and is no longer in active production. The LSM6D is the active production equivalent within the same HDLS series, ensuring continued availability and supply chain reliability.

Q: Are there any differences in electrical ratings between the LSM6D4 and LSM6D?

A: No. Both parts are rated for 10A AC at 120V and 800mA DC at 115V. Current and voltage specifications are identical.

Q: Do the mechanical specifications match between these parts?

A: Yes. Operating force (46gfm), pretravel (18°), differential travel (10°), and overtravel (57°) are identical. The side rotary actuator without lever and chassis mount configuration are the same.

Q: What is the operating temperature range for the LSM6D?

A: The operating temperature range is -1°C to 121°C, identical to the LSM6D4.

Q: Is the LSM6D RoHS compliant?

A: Yes. The LSM6D is RoHS compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, matching the LSM6D4 specifications.

Q: What packaging is available for the LSM6D?

A: The LSM6D is supplied in bulk packaging. This is standard for industrial switch applications and does not affect functional performance or integration into existing circuits.

Q: Are there any certifications or compliance differences between the LSM6D4 and LSM6D?

A: The LSM6D carries REACH Unaffected status in addition to RoHS compliance. Both parts meet the same regulatory requirements for industrial applications.
