Substitute Part Grouping Explanation

The D3V-11-1C24 is identified as a manufacturer-recommended substitute for the D3V-6-3C24. Substitution eligibility is determined by the following critical parameters:

Mechanical Compatibility:

• Same series (D3V) ensures mechanical interchangeability
• Identical actuator type (Round Pin Plunger) and mounting configuration (Chassis Mount)
• Matching termination style (Quick Connect - 0.187") and connector footprint
• Identical operating position (0.579"), pretravel (0.047"), differential travel (0.016"), and overtravel (0.040")
• Same ingress protection rating (IP40)

Electrical Compatibility Considerations:

• Both parts operate within the same voltage ratings (250V AC / 125V DC)
• Operating temperature range remains identical (-25°C to 105°C)
• The substitute provides higher current capacity (11A AC / 600mA DC), making it suitable for applications requiring equal or lower current demands than the original 6A AC / 400mA DC specification

Circuit Configuration Difference:

• Main part: SPST-NO (Single Pole Single Throw - Normally Open)
• Substitute: SPDT (Single Pole Double Throw)
• This difference requires circuit-level evaluation; SPDT functionality can accommodate SPST-NO applications when only the NO contact is utilized

Engineering Selection Recommendations

The D3V-11-1C24 is the manufacturer-recommended substitute for the D3V-6-3C24. Selection of this substitute is supported by the following factors:

Product Status: The D3V-6-3C24 is in Last Time Buy status, indicating end-of-life production. The D3V-11-1C24 maintains Active product status, ensuring ongoing availability and supply chain continuity.

Compliance: Both parts maintain RoHS compliance. The substitute achieves ROHS3 compliance, meeting current regulatory requirements. Both parts are classified as EAR99 and carry identical HTSUS codes (8536.50.7000), confirming regulatory equivalence.

Mechanical Interchangeability: Identical mechanical specifications across actuator type, mounting configuration, termination style, and operational travel distances ensure direct physical replacement without enclosure or mechanical redesign.

Electrical Capability: The substitute's higher current rating (11A AC / 600mA DC) accommodates applications operating at or below the original part's specifications (6A AC / 400mA DC). Voltage ratings and operating temperature ranges are identical.

Circuit Configuration: The SPDT configuration of the substitute provides additional switching capability compared to the SPST-NO original. Applications utilizing only the normally open contact require no circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the D3V-11-1C24 directly replace the D3V-6-3C24 in existing designs?

A: Mechanical and electrical compatibility is confirmed for applications operating at or below the original part's current specifications. The SPDT circuit configuration of the substitute accommodates SPST-NO applications when only the NO contact is utilized. Circuit-level verification is required to confirm contact assignment compatibility with existing wiring.

Q: What is the significance of the SPDT versus SPST-NO circuit difference?

A: SPDT (Single Pole Double Throw) provides both normally open and normally closed contacts, while SPST-NO (Single Pole Single Throw - Normally Open) provides only a normally open contact. The substitute's SPDT configuration can function in SPST-NO applications by utilizing only the NO contact, leaving the NC contact unused.

Q: Are the packaging and termination specifications identical?

A: Both parts feature identical Quick Connect termination (0.187" / 4.7mm) and are supplied in Bulk packaging. Connector footprint and pin spacing are mechanically equivalent.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant. The D3V-6-3C24 carries RoHS Compliant status, while the D3V-11-1C24 achieves ROHS3 Compliant status. Both are classified as EAR99 for export control purposes and share identical HTSUS commodity codes.

Q: Why is the D3V-6-3C24 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production of this part number. The D3V-11-1C24 remains in Active production status, making it the recommended path for continued supply and future designs.

Q: Are there any electrical performance differences in switching characteristics?

A: Operating force (100gf), release force (15gf), and mechanical life (10,000,000 cycles) are identical. The substitute exhibits lower electrical life (200,000 cycles versus 500,000 cycles), which may be relevant for high-cycle applications.
