Honeywell V3L-112-D8 Snap Action Switch: Equivalent & Substitute Parts

Part Overview

The Honeywell V3L-112-D8 is a snap action SPDT switch with chassis mount configuration, rated for 11A AC at 125V and 500mA DC at 125V. This component features a straight lever actuator with quick connect 0.187" (4.7mm) termination style. The V3L-112-D8 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete V3L-112-D8 is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 11A AC, 500mA DC
• Voltage rating: 125V AC and DC
• Actuator type: Lever, Straight
• Mounting type: Chassis Mount
• Termination style: Quick Connect - 0.187" (4.7mm)

Acceptable Variation Parameters:

• Operating force, release force, pretravel, differential travel, and overtravel may vary within mechanical design tolerances
• Operating temperature range may be extended in active substitutes
• Electrical and mechanical life specifications may be enhanced in active substitutes

The Honeywell V7 series snap action switches meet all mandatory equivalence criteria. Two active substitute models are identified: V7-1B17D8-048 and V7-2B17D8-048, both manufactured by Honeywell Sensing and Productivity Solutions with active product status.

Parameter Comparison

Engineering Selection Recommendations

Both V7-1B17D8-048 and V7-2B17D8-048 are qualified substitutes for the obsolete V3L-112-D8 based on electrical and mechanical parameter equivalence. Selection between the two active alternatives depends on application-specific actuation force requirements:

V7-1B17D8-048 provides an operating force of 50gf with a release force of 4.000gf, representing a closer mechanical match to the original V3L-112-D8 specifications (46gf operating force, 6.000gf release force).

V7-2B17D8-048 features a reduced operating force of 20gf with a release force of 1.000gf, suitable for applications requiring lighter actuation.

Both substitutes offer enhanced reliability specifications with defined operating temperature range (-40°C ~ 85°C), electrical life (100,000 cycles), and mechanical life (10,000,000 cycles). Both maintain RoHS compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can V7-1B17D8-048 and V7-2B17D8-048 be used interchangeably with V3L-112-D8?

A: Both V7 series switches satisfy all mandatory electrical and mechanical substitution criteria: SPDT circuit, 11A AC / 500mA DC current rating, 125V AC/DC voltage rating, straight lever actuator, chassis mount configuration, and 0.187" quick connect termination. Interchangeability is confirmed for these parameters. Differences in operating force and release force must be evaluated against specific application requirements.

Q: What are the key differences between V7-1B17D8-048 and V7-2B17D8-048?

A: The primary distinction is actuation force. V7-1B17D8-048 requires 50gf operating force with 4.000gf release force. V7-2B17D8-048 requires 20gf operating force with 1.000gf release force. Both share identical electrical ratings, mounting configuration, and termination style. Selection depends on whether the application requires standard or light-touch actuation.

Q: Are there packaging differences between the substitute parts?

A: Both V7-1B17D8-048 and V7-2B17D8-048 are supplied in bulk packaging. The original V3L-112-D8 packaging specification is not provided in the technical data. Bulk packaging is standard for both active substitutes.

Q: Do the V7 series substitutes provide improved specifications compared to the V3L-112-D8?

A: The V7 series substitutes include defined operating temperature range (-40°C ~ 85°C), electrical life specification (100,000 cycles), and mechanical life specification (10,000,000 cycles). The original V3L-112-D8 does not include these specifications in the provided data. Both substitutes maintain RoHS compliance and MSL 1 rating.

Q: What is the inventory status for these substitute parts?

A: V7-1B17D8-048 has 1,450 pieces in stock. V7-2B17D8-048 has 3,718 pieces in stock. Both are active products with established supply availability.
