Key Parameters

Substitute Part Grouping Explanation

Substitution of the PVB6 OA 300 NS LFS is determined by the following critical parameters:

Circuit Configuration: Both the main part and substitute must maintain DPDT topology to preserve electrical functionality in dual-pole switching applications.

Switch Function: On-Momentary operation must be preserved to ensure correct behavioral characteristics in the target application.

Mounting Type and Termination: Surface mount configuration with gull wing termination ensures mechanical and electrical compatibility with existing PCB layouts.

Electrical Ratings: The substitute part must meet or exceed the voltage and current requirements. The PVB6 OA 300 NS LFS operates at 14V DC with 200mA capacity. Substitute parts with higher voltage and current ratings remain compatible, as they operate within the same electrical envelope.

Environmental Compliance: RoHS compliance status ensures regulatory alignment for modern manufacturing and end-of-life requirements.

The G3B25AP-S from NKK Switches satisfies all substitution criteria through equivalent DPDT circuit configuration, On-Momentary function, surface mount gull wing termination, and superior electrical ratings (28V, 0.4VA) that encompass the original specification.

Engineering Selection Recommendations

The G3B25AP-S is a direct functional substitute for the PVB6 OA 300 NS LFS. Selection is based on the following engineering criteria:

Electrical Compatibility: The G3B25AP-S operates at 28V DC with 0.4VA capacity, which exceeds the original part's 14V, 200mA specification. This higher rating ensures the substitute operates safely within the original application's electrical envelope without derating.

Circuit Equivalence: Both parts maintain identical DPDT configuration and On-Momentary switching behavior, ensuring functional parity in dual-pole switching applications.

Mechanical Compatibility: Surface mount configuration with gull wing termination on both parts ensures direct PCB layout compatibility without redesign.

Product Status and Compliance: The G3B25AP-S is an active product with ROHS3 compliance, providing long-term availability and regulatory alignment. The original PVB6 OA 300 NS LFS is obsolete, making the G3B25AP-S the appropriate selection for new procurement and system maintenance.

Environmental Performance: The G3B25AP-S operating temperature range (-30°C to 85°C) and extended electrical life (50,000 cycles) provide enhanced reliability compared to the original specification.

Frequently Asked Questions (FAQ)

Q: Can the G3B25AP-S directly replace the PVB6 OA 300 NS LFS without PCB modification?

A: Yes. Both parts feature identical surface mount configuration with gull wing termination. No PCB layout changes are required for mechanical or electrical integration.

Q: What is the significance of the higher voltage rating on the G3B25AP-S?

A: The G3B25AP-S is rated for 28V DC compared to the original 14V specification. This higher rating indicates the substitute can safely operate in the original 14V application without derating. The component operates within its electrical envelope and maintains full performance characteristics.

Q: Are there differences in actuator design between these parts?

A: Yes. The PVB6 OA 300 NS LFS features a square plunger actuator, while the G3B25AP-S uses a round plunger with gray coloring. These differences are cosmetic and do not affect electrical function or mechanical compatibility in standard applications.

Q: What is the packaging difference, and does it affect compatibility?

A: The G3B25AP-S is supplied in tube packaging, while the original part number does not specify packaging format. This difference applies only to procurement and handling; it does not affect component performance or PCB integration.

Q: Why does the G3B25AP-S have extended electrical life?

A: The G3B25AP-S is rated for 50,000 electrical cycles compared to 30,000 cycles for the PVB6 OA 300 NS LFS. This extended life reflects the active product status and modern manufacturing standards of the NKK Switches component.

Q: Is the G3B25AP-S suitable for new designs?

A: Yes. The G3B25AP-S is an active product with current manufacturing support, ROHS3 compliance, and superior electrical specifications. It is appropriate for both legacy component replacement and new design implementations.
