• Circuit configuration: DPDT (DB/DM)
• Switch function: Mom-Off-Mom
• Current rating: 10A AC, 800mA DC
• Voltage rating: 120V AC, 115V DC

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary, Roller
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force: 46gfm
• Travel specifications: Pretravel 18°, Differential Travel 10°, Overtravel 57°
• Operating temperature range: -40°C to 121°C

Compliance Criteria:

• RoHS Compliant status
• Moisture Sensitivity Level 1

The LSYMB7N-1D meets all electrical, mechanical, and compliance requirements for direct substitution with the LSYMB7N-1C. The primary distinction between these parts is product status and roller material composition.

Parameter Comparison

Engineering Selection Recommendations

LSYMB7N-1D as Primary Substitute:

The LSYMB7N-1C is classified as obsolete. The LSYMB7N-1D is the direct equivalent part with active product status from the same manufacturer and series. Both parts share identical electrical ratings, mechanical specifications, and compliance certifications. The LSYMB7N-1D is suitable for new designs and replacement applications where the LSYMB7N-1C is no longer available.

Material Consideration:

The LSYMB7N-1D features a steel roller actuator, whereas the LSYMB7N-1C uses a nylon roller. Both configurations maintain the specified operating force of 46gfm and travel characteristics. Material selection between steel and nylon rollers does not affect electrical performance or switching characteristics within the defined operating parameters.

Compliance and Certification:

Both parts maintain RoHS Compliance and Moisture Sensitivity Level 1 (Unlimited), ensuring compatibility with current regulatory requirements and manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can LSYMB7N-1D directly replace LSYMB7N-1C in existing applications?

A: Yes. The LSYMB7N-1D meets all electrical and mechanical specifications of the LSYMB7N-1C. Both parts are DPDT Mom-Off-Mom switches with identical current ratings (10A AC, 800mA DC), voltage ratings (120V AC, 115V DC), actuator type (Side Rotary, Roller), mounting configuration (Chassis Mount), and operating characteristics (46gfm operating force, 18° pretravel, 10° differential travel, 57° overtravel).

Q: What is the difference between LSYMB7N-1C and LSYMB7N-1D?

A: The primary differences are product status and roller material. LSYMB7N-1C is obsolete with a nylon roller, while LSYMB7N-1D is active with a steel roller. All electrical and mechanical performance parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both LSYMB7N-1C and LSYMB7N-1D are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the operating temperature range for these switches?

A: Both parts operate across -40°C to 121°C, suitable for industrial and commercial applications requiring wide temperature tolerance.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both parts use identical screw terminal termination style for chassis mount installation.

Q: Which part should be selected for new designs?

A: LSYMB7N-1D should be selected for new designs due to its active product status and current availability from Honeywell Sensing and Productivity Solutions.
