Omron D3V-6-3C4 Equivalent & Substitute Parts

Part Overview

The Omron D3V-6-3C4 is a snap-action switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 6A AC at 250V and 400mA DC at 125V. This chassis-mounted switch features a round pin plunger actuator with quick connect termination and IP40 ingress protection. The part is currently in Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D3V-6-3C4 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the Omron D3V series to ensure mechanical and electrical compatibility with existing mounting and termination infrastructure.
• Mounting and Termination: Chassis mount configuration with quick connect 0.250" (6.3mm) termination must be maintained.
• Actuator Type: Round pin plunger actuator ensures identical mechanical interface and actuation characteristics.
• Voltage Ratings: AC and DC voltage ratings must meet or exceed the original specification (250V AC / 125V DC minimum).
• Operating Temperature: Must support the -25°C to 105°C operating range.
• Ingress Protection: IP40 rating must be maintained for environmental sealing requirements.

The D3V-11-1C4 qualifies as a substitute based on these parameters. While it features a different circuit configuration (SPDT instead of SPST-NO) and higher current rating (11A AC instead of 6A AC), it maintains all mechanical compatibility requirements and exceeds electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

The D3V-11-1C4 is available as an active product from Omron Electronics Inc-EMC Div, providing supply continuity for applications currently using the D3V-6-3C4. Both parts maintain RoHS compliance, with the D3V-11-1C4 meeting ROHS3 standards. The substitute part exceeds the electrical performance specifications of the original part, supporting higher current ratings (11A AC vs. 6A AC) and increased DC current capacity (600mA vs. 400mA). Mechanical compatibility is preserved through identical actuator type, mounting configuration, and termination style. The D3V-11-1C4 maintains the same operating temperature range and ingress protection rating. Circuit configuration differs (SPDT vs. SPST-NO), requiring circuit design evaluation to confirm functional compatibility with the application.

Frequently Asked Questions (FAQ)

Q: Can the D3V-11-1C4 directly replace the D3V-6-3C4 in existing applications?

A: Mechanical and electrical compatibility is maintained. However, the circuit configuration differs: the D3V-11-1C4 is SPDT (Single Pole Double Throw) while the D3V-6-3C4 is SPST-NO (Single Pole Single Throw - Normally Open). Circuit design evaluation is required to confirm functional compatibility.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical actuator type (round pin plunger), mounting configuration (chassis mount), termination style (quick connect 0.250"), and ingress protection rating (IP40). Physical installation compatibility is maintained.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The D3V-11-1C4 meets ROHS3 standards, providing enhanced compliance status. Both parts are rated for the same operating temperature range (-25°C to 105°C) and maintain equivalent environmental sealing.

Q: How do the electrical ratings compare?

A: The D3V-11-1C4 provides higher electrical performance: 11A AC at 250V (vs. 6A AC) and 600mA DC at 125V (vs. 400mA DC). Voltage ratings remain identical at 250V AC and 125V DC. The substitute part exceeds the original specifications.

Q: What is the difference in electrical life between these parts?

A: The D3V-6-3C4 is rated for 500,000 electrical cycles, while the D3V-11-1C4 is rated for 200,000 electrical cycles. Both maintain 10,000,000 mechanical life cycles. Application duty cycle requirements should be evaluated accordingly.

Q: Why is the D3V-6-3C4 in Last Time Buy status?

A: Last Time Buy status indicates discontinued production. The D3V-11-1C4 remains in active production, providing a path for continued component availability and supply chain continuity.
