LSYDB6B Snap Action Switch - Equivalent & Substitute Parts

Part Overview

The LSYDB6B is a snap action DPDT (double pole double throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This component features a roller plunger actuator, chassis mount configuration, and plug-in termination style. It is rated for 10A AC at 120V and 800mA DC at 115V, with an operating temperature range of -40°C to 93°C.

The LSYDB6B carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSYDB6B is determined by strict equivalence across the following critical parameters:

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

Mechanical Parameters: Actuator type (roller plunger), mounting type (chassis mount), termination style (plug-in), operating force (1814gf), pretravel (0.071"), differential travel (0.020"), and overtravel (0.190") must be identical.

Environmental & Compliance Parameters: Operating temperature range, RoHS compliance status, and moisture sensitivity level must be compatible with the original application requirements.

The LSD6B meets these substitution criteria and is identified as an equivalent part for the LSYDB6B.

Parameter Comparison

*Operating temperature range note: LSD6B minimum operating temperature is -12°C, which is higher than LSYDB6B at -40°C. Applications requiring operation below -12°C must account for this difference.

Engineering Selection Recommendations

The LSD6B is the direct equivalent substitute for the LSYDB6B based on identical electrical, mechanical, and compliance specifications across all critical parameters.

Product Status Advantage: The LSD6B carries an active product status, ensuring ongoing availability and supply chain support. The LSYDB6B is obsolete and no longer manufactured.

Compliance Certification: Both parts maintain RoHS compliance and identical moisture sensitivity ratings, supporting regulatory and environmental requirements.

Temperature Range Consideration: The LSD6B operates across -12°C to 93°C, compared to the LSYDB6B range of -40°C to 93°C. Applications requiring operation below -12°C must evaluate this specification difference against system requirements.

Packaging Difference: The LSYDB6B is supplied in standard packaging, while the LSD6B is supplied in bulk packaging. Procurement and inventory management processes should account for this distinction.

Frequently Asked Questions (FAQ)

Q: Can the LSD6B directly replace the LSYDB6B in existing designs?

A: Yes. The LSD6B is electrically and mechanically equivalent to the LSYDB6B across all critical parameters: DPDT circuit configuration, 10A AC / 800mA DC current ratings, 120V AC / 115V DC voltage ratings, roller plunger actuator, chassis mount configuration, and plug-in termination. Physical dimensions, mounting interfaces, and electrical performance are identical.

Q: What is the difference between LSYDB6B and LSD6B?

A: The primary differences are product status and operating temperature range. The LSYDB6B is obsolete with an operating range of -40°C to 93°C. The LSD6B is an active product with an operating range of -12°C to 93°C. All other electrical, mechanical, and compliance specifications are identical.

Q: Does the operating temperature range difference affect substitution?

A: The LSD6B minimum operating temperature of -12°C is higher than the LSYDB6B minimum of -40°C. If your application requires operation below -12°C, the LSD6B may not be suitable. For applications operating within -12°C to 93°C, the LSD6B is fully compatible.

Q: Are there packaging considerations when switching from LSYDB6B to LSD6B?

A: Yes. The LSYDB6B uses standard packaging while the LSD6B is supplied in bulk packaging. Procurement specifications, inventory management, and handling procedures may require adjustment to accommodate bulk packaging requirements.

Q: Is the LSD6B RoHS compliant?

A: Yes. The LSD6B is RoHS compliant with a moisture sensitivity level of 1 (unlimited), matching the LSYDB6B compliance profile.

Q: What is the base product number for the LSD6B?

A: The base product number for the LSD6B is LSD6, which identifies the core product family within the Honeywell HDLS series.
