LSYNB7L Equivalent & Substitute Parts Reference

Part Overview

The LSYNB7L is a snap action DPDT (double-pole double-throw) switch manufactured by Honeywell Sensing and Productivity Solutions, designed for chassis mount applications with screw terminal connections. This component operates at 10A AC (120V) and 800mA DC (115V) with a side rotary actuator configuration and no lever mechanism.

The LSYNB7L is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LSYNB7L is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be DPDT (DB/DM)
• Switch function must be On-On
• Current rating must support minimum 10A AC at 120V and 800mA DC at 115V
• Voltage ratings must match or exceed specified values

Mechanical Compatibility Requirements:

• Actuator type must be Side Rotary - No Lever
• Mounting type must be Chassis Mount
• Termination style must be Screw Terminal
• Operating force must be 46gfm
• Travel specifications (pretravel 65°, differential travel 40°, overtravel 20°) must be identical

Environmental & Compliance Requirements:

• Operating temperature range must encompass or match the specified range
• RoHS compliance status must be maintained
• Moisture sensitivity level must be 1 (Unlimited)

Only components meeting all these criteria are classified as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

LSN7L as Primary Substitute:

The LSN7L is a direct functional equivalent to the LSYNB7L across all critical electrical and mechanical parameters. Both components are manufactured by Honeywell Sensing and Productivity Solutions within the HDLS series and share identical circuit configuration, current and voltage ratings, actuator type, mounting configuration, and termination style.

Compliance Status:

Both the LSYNB7L and LSN7L maintain RoHS compliance and identical moisture sensitivity classification (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility in applications requiring these certifications.

Product Status Consideration:

The LSYNB7L is classified as obsolete, while the LSN7L is classified as active. The active status of the LSN7L ensures ongoing availability and continued manufacturing support from Honeywell Sensing and Productivity Solutions.

Temperature Range Variance:

The LSN7L operating temperature range (-1°C ~ 121°C) is narrower at the lower temperature limit compared to the LSYNB7L (-29°C ~ 121°C). Applications requiring operation below -1°C must account for this specification difference.

Frequently Asked Questions (FAQ)

Q: Can LSN7L be used as a direct replacement for LSYNB7L in existing designs?

A: LSN7L meets all critical electrical and mechanical specifications of LSYNB7L, including circuit configuration, current/voltage ratings, actuator type, mounting method, and termination style. The primary consideration is the operating temperature range, which is narrower for LSN7L at the lower limit (-1°C versus -29°C).

Q: What is the significance of the product status difference between LSYNB7L (Obsolete) and LSN7L (Active)?

A: Obsolete status indicates the LSYNB7L is no longer manufactured or supported by Honeywell. Active status for LSN7L confirms current production and availability. For new designs or ongoing production requirements, LSN7L provides supply chain continuity.

Q: Are the mechanical specifications identical between these two parts?

A: Yes. Both components share identical specifications for actuator type (Side Rotary - No Lever), mounting type (Chassis Mount), termination style (Screw Terminal), operating force (46gfm), pretravel (65°), differential travel (40°), and overtravel (20°).

Q: Do both parts meet the same regulatory and environmental standards?

A: Yes. Both LSYNB7L and LSN7L are RoHS compliant and classified as MSL 1 (Unlimited moisture sensitivity level), ensuring equivalent compliance for regulated applications.

Q: What is the inventory status for these parts?

A: LSYNB7L has 665 pieces in stock (new original). LSN7L has 868 pieces in stock (new original). Both are available for immediate procurement.

Q: Are there any electrical performance differences between LSYNB7L and LSN7L?

A: No. Both components are rated for 10A AC at 120V and 800mA DC at 115V with identical DPDT On-On circuit configuration and switching characteristics.
