Honeywell LSC2C Snap Action Switch: Equivalent & Substitute Parts

Part Overview

The Honeywell LSC2C is a DPDT snap action switch rated for 10A at 120V AC and 800mA at 115V DC. This component features a round pin plunger actuator, chassis mount configuration, and plug-in termination style. The LSC2C is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement.

The LSC2C belongs to the HDLS series and is RoHS compliant with MSL Level 1 rating. Due to its obsolete status, the LSC2B serves as the direct functional equivalent while maintaining active product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LSC2C is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish valid substitution:

Electrical Parameters (Critical):

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

Mechanical Parameters (Critical):

• Actuator type: Round (Pin Plunger)
• Mounting type: Chassis Mount
• Termination style: Plug In
• Operating force: 1814gf
• Pretravel: 0.071" (1.8mm)
• Differential travel: 0.020" (0.5mm)
• Overtravel: 0.190" (4.8mm)

Environmental Parameters (Critical):

• Operating temperature range: -12°C to 93°C
• RoHS compliance: Required
• MSL rating: 1 (Unlimited)

The LSC2B meets all specified electrical, mechanical, and environmental parameters, establishing it as a direct substitute for the obsolete LSC2C.

Parameter Comparison

Engineering Selection Recommendations

The LSC2B is the appropriate substitute for the obsolete LSC2C based on the following factors:

Functional Equivalence: All electrical parameters, mechanical specifications, and environmental ratings are identical between the two components. The LSC2B maintains the same DPDT circuit configuration, 10A AC / 800mA DC current capacity, and 120V AC / 115V DC voltage ratings.

Compliance Status: Both components are RoHS compliant and carry MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Product Availability: The LSC2B is classified as active product status with confirmed inventory availability (1066 pieces in stock), whereas the LSC2C is obsolete. This availability differential makes the LSC2B the necessary selection for new procurement and system maintenance.

Mechanical Compatibility: Identical actuator type, mounting configuration, and termination style ensure direct mechanical fit and electrical interface compatibility in existing applications.

Frequently Asked Questions (FAQ)

Q: Can the LSC2B directly replace the LSC2C in existing applications?

A: Yes. The LSC2B is electrically and mechanically identical to the LSC2C across all specified parameters. The plug-in termination style and chassis mount configuration ensure direct compatibility without modification.

Q: What is the primary reason for substitution?

A: The LSC2C is classified as obsolete product status. The LSC2B, which is active and in stock, provides functional equivalence while ensuring ongoing component availability for procurement and maintenance.

Q: Are there any differences in packaging between LSC2C and LSC2B?

A: The LSC2C is supplied in standard packaging, while the LSC2B is supplied in bulk packaging. This difference does not affect component functionality or electrical performance.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both the LSC2C and LSC2B are RoHS compliant and carry MSL Level 1 rating, meeting current environmental and moisture sensitivity standards.

Q: Are the mechanical specifications identical?

A: Yes. Operating force (1814gf), pretravel (0.071" / 1.8mm), differential travel (0.020" / 0.5mm), and overtravel (0.190" / 4.8mm) are identical between both components.

Q: What is the operating temperature range for both parts?

A: Both the LSC2C and LSC2B operate across the temperature range of -12°C to 93°C.

Q: Is the LSC2B available in sufficient quantity?

A: Yes. The LSC2B has confirmed inventory of 1066 pieces in stock as new original components.
