Omron D3V-6-3C4-K Equivalent & Substitute Parts

Part Overview

The Omron D3V-6-3C4-K 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 designated as Last Time Buy, indicating discontinued production status. Identifying equivalent and substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this switch function is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D3V-6-3C4-K is determined by the following critical parameters:

Mechanical Compatibility:

• Actuator type (Round pin plunger)
• Mounting configuration (Chassis mount)
• Termination style (Quick connect 0.250" / 6.3mm)
• Operating position and travel characteristics
• Physical envelope dimensions

Electrical Compatibility:

• Voltage ratings (AC and DC)
• Current capacity requirements
• Circuit configuration capability
• Operating temperature range
• Environmental protection rating (IP40)

Regulatory & Compliance:

• RoHS compliance status
• ECCN and HTSUS classifications

The substitute part D3V-11G-1C4-K shares the same series (D3V), manufacturer, actuator type, mounting method, termination style, voltage ratings, temperature range, and compliance certifications. However, it differs in circuit configuration (SPDT vs. SPST-NO) and current ratings, which affects its application suitability.

Parameter Comparison

Engineering Selection Recommendations

The D3V-11G-1C4-K is listed as an active product within the same D3V series, providing continued availability compared to the Last Time Buy status of the D3V-6-3C4-K. Both parts maintain identical mechanical interfaces, voltage ratings, temperature operating range, and RoHS compliance.

Selection between these parts depends on circuit configuration requirements. The D3V-6-3C4-K provides SPST-NO functionality with 6A AC capacity, while the D3V-11G-1C4-K provides SPDT functionality with 11A AC capacity but reduced DC current rating (100mA vs. 400mA). The D3V-11G-1C4-K's higher AC current rating and active product status support long-term supply chain continuity for applications requiring SPDT switching logic.

Frequently Asked Questions (FAQ)

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

A: Direct replacement depends on circuit configuration requirements. The D3V-6-3C4-K is SPST-NO (single throw), while the D3V-11G-1C4-K is SPDT (double throw). Applications requiring single-throw logic cannot use the SPDT substitute without circuit redesign. Additionally, DC current requirements must be evaluated, as the substitute provides 100mA DC versus the original 400mA DC.

Q: Are the mechanical interfaces identical?

A: Yes. Both parts share identical actuator type (round pin plunger), chassis mount configuration, quick connect termination (0.250" / 6.3mm), and operating position (0.579" / 14.7mm). Physical mounting and connection are compatible.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy indicates the D3V-6-3C4-K is discontinued and no longer in production. The D3V-11G-1C4-K's Active status ensures ongoing availability for future orders and supply chain reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the D3V-6-3C4-K and D3V-11G-1C4-K are RoHS Compliant and share identical ECCN (EAR99) and HTSUS (8536.50.7000) classifications.

Q: What are the key differences in electrical ratings?

A: The D3V-6-3C4-K is rated 6A AC at 250V and 400mA DC at 125V. The D3V-11G-1C4-K is rated 11A AC at 250V and 100mA DC at 125V. AC voltage ratings are identical; however, AC current capacity differs, as does DC current capacity. Application voltage and current requirements must be verified before substitution.

Q: Do both switches operate within the same temperature range?

A: Yes. Both parts operate across -25°C to 105°C, ensuring thermal compatibility in equivalent environmental conditions.
