Key Parameters

Substitute Part Grouping Explanation

The V7-1B17D8-022 from Honeywell Sensing and Productivity Solutions is identified as a substitute based on the following alignment criteria:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Actuator type: Lever, Straight
• Mounting type: Chassis Mount
• Termination style: Quick Connect - 0.187" (4.7mm)
• Operating temperature range: -40°C to 85°C
• RoHS compliance: Active product status with compliance certification

Parameter Variations: The V7-1B17D8-022 operates at reduced current and voltage ratings (11A AC at 125V) compared to the D459-R1LL-G2 (16A AC at 250V). This substitute is suitable for applications where the lower electrical ratings are acceptable. The V7-1B17D8-022 provides extended electrical life (100,000 cycles versus 50,000 cycles) and includes mechanical life specification (10,000,000 cycles).

Parameter Comparison

Engineering Selection Recommendations

D459-R1LL-G2 Selection Criteria: Select the D459-R1LL-G2 for applications requiring 16A at 250V AC with explosion-proof construction. This part is active and RoHS3 compliant. The lower operating force (22gf) and release force (5.099gf) make it suitable for applications with sensitive actuation requirements.

V7-1B17D8-022 Selection Criteria: Select the V7-1B17D8-022 for applications where current requirements do not exceed 11A AC at 125V. This substitute offers extended electrical life (100,000 cycles) and documented mechanical life (10,000,000 cycles). The part is RoHS compliant and active. Higher operating force (82gf) and release force (8.000gf) may be relevant for applications requiring more deliberate actuation.

Compliance Considerations: Both parts maintain MSL rating 1 (Unlimited) and are suitable for standard storage and handling conditions. The D459-R1LL-G2 carries RoHS3 compliance, while the V7-1B17D8-022 carries RoHS compliance. Both are classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can the V7-1B17D8-022 replace the D459-R1LL-G2 in all applications?

A: No. The V7-1B17D8-022 is suitable only for applications where the electrical load does not exceed 11A AC at 125V. If your application requires 16A at 250V AC, the D459-R1LL-G2 is the required selection.

Q: What are the key mechanical differences between these switches?

A: Operating force differs significantly: D459-R1LL-G2 requires 22gf while V7-1B17D8-022 requires 82gf. Operating position is nearly identical (0.600" versus 0.602"). Both use identical termination style and mounting configuration.
