Substitute Part Grouping Explanation

The D3V-64-3C4 has one manufacturer-recommended substitute: D3V-114-1C4. This substitution is valid based on the following shared mechanical and electrical parameters:

Common Parameters Enabling Substitution:

• Same manufacturer series (D3V)
• Identical actuator type (Lever, Simulated Roller)
• Identical mounting type (Chassis Mount)
• Identical termination style (Quick Connect - 0.250")
• Identical ingress protection rating (IP40)
• Identical operating temperature range (-25°C to 105°C)
• Identical mechanical life rating (10,000,000 Cycles)
• Same voltage ratings (250V AC, 125V DC)

Differences Requiring Design Review:

• Circuit configuration changes from SPST-NO to SPDT
• Switch function changes from Off-Mom to On-Mom
• Current ratings increase (6A AC to 11A AC; 400mA DC to 600mA DC)
• Electrical life decreases (500,000 to 200,000 cycles)

Parameter Comparison

Engineering Selection Recommendations

The D3V-114-1C4 is designated as the manufacturer-recommended substitute for the D3V-64-3C4. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The substitute part is currently in Active product status, providing long-term availability compared to the Last Time Buy status of the original part.

Selection of the D3V-114-1C4 requires circuit redesign consideration due to the change from SPST-NO to SPDT configuration and from Off-Mom to On-Mom operation. The increased current ratings (11A AC and 600mA DC) provide design margin for applications within the original 6A AC and 400mA DC specifications. The reduced electrical life (200,000 cycles versus 500,000 cycles) must be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the D3V-114-1C4 directly replace the D3V-64-3C4 without circuit modification?

A: No. The D3V-114-1C4 has a different circuit configuration (SPDT versus SPST-NO) and switch function (On-Mom versus Off-Mom). Circuit redesign is required to accommodate these functional differences.

Q: Are the mechanical mounting and termination characteristics identical?

A: Yes. Both parts share identical actuator type, mounting type (Chassis Mount), termination style (Quick Connect - 0.250"), and ingress protection rating (IP40), ensuring mechanical compatibility in the same enclosure footprint.

Q: What is the impact of the reduced electrical life rating?

A: The D3V-114-1C4 has an electrical life of 200,000 cycles compared to 500,000 cycles for the D3V-64-3C4. Applications with high switching frequency must evaluate whether this reduced rating meets operational requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the D3V-64-3C4 and D3V-114-1C4 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the advantage of the higher current ratings in the substitute part?

A: The D3V-114-1C4 is rated for 11A AC and 600mA DC, compared to 6A AC and 400mA DC for the original part. This provides design margin for applications operating within the original specifications and allows for potential future load increases.

Q: Is the operating temperature range the same for both parts?

A: Yes. Both parts operate across the identical temperature range of -25°C to 105°C, ensuring thermal compatibility in the same application environment.
