Key Parameters

Substitute Part Grouping Explanation

Substitution of the KB25CKG01-GG is determined by the following critical parameters:

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

Switch Function Match: On-Momentary function must be preserved to ensure the switch returns to its default state upon release, maintaining compatibility with momentary-action control circuits.

Mounting Compatibility: Panel Mount, Front mounting type with compatible panel cutout dimensions ensures mechanical fit within existing enclosures. The substitute YB25WCKW01-GB features a 16.00mm circular cutout, which represents a larger opening and may require panel modification.

Voltage and Current Ratings: The substitute part YB25WCKW01-GB is rated for 3A at 125V AC and 30V DC, providing significantly higher electrical capacity than the KB25CKG01-GG (0.4VA at 28V). This represents an upward-compatible substitution where the substitute can safely handle the original part's electrical requirements.

Actuator and Termination: Both parts feature round button actuators with blue coloring. The KB25CKG01-GG uses Solder Lug termination, while YB25WCKW01-GB offers Solder and Quick Connect options, requiring termination method verification during integration.

Environmental and Compliance: Both parts operate within the -25°C to 70°C temperature range, maintain ROHS3 compliance, and feature MSL 1 rating, ensuring compatibility in regulated applications.

Parameter Comparison

Engineering Selection Recommendations

The YB25WCKW01-GB qualifies as a functional substitute for the KB25CKG01-GG based on the following engineering criteria:

Product Status Alignment: The KB25CKG01-GG is obsolete, while YB25WCKW01-GB is active production status, ensuring long-term availability and supply chain continuity.

Electrical Compatibility: The substitute part's higher current (3A) and voltage ratings (125V AC, 30V DC) exceed the original part's requirements (0.4VA at 28V), providing upward-compatible electrical performance without derating concerns.

Compliance Certification: Both parts maintain ROHS3 compliance and MSL 1 rating, satisfying regulatory requirements for equivalent component selection in controlled environments.

Mechanical Considerations: Panel cutout diameter difference (16.00mm substitute versus 12.30mm original) requires physical verification. The larger opening may necessitate panel modification or use of adapter hardware depending on enclosure design.

Termination Verification: Termination method compatibility must be confirmed during integration. The substitute offers multiple termination options (Solder and Quick Connect), providing flexibility for different assembly approaches.

Enhanced Durability: The substitute's mechanical life rating (1,000,000 cycles) significantly exceeds the original part (100,000 cycles), offering improved longevity in high-cycle applications.

Frequently Asked Questions (FAQ)

Q: Can YB25WCKW01-GB directly replace KB25CKG01-GG without circuit modifications?

A: Yes, from an electrical standpoint. Both parts feature identical DPDT circuit configuration and On-Momentary switch function. The substitute's higher electrical ratings are backward-compatible with the original part's 0.4VA/28V specification. However, panel cutout diameter difference (16.00mm versus 12.30mm) requires mechanical verification.

Q: What is the significance of the panel cutout diameter difference?

A: The KB25CKG01-GG requires a 12.30mm circular opening, while YB25WCKW01-GB requires 16.00mm. If the original enclosure has a 12.30mm cutout, the larger substitute will not fit without panel modification. Verify panel dimensions before selection.

Q: Are the termination styles compatible?

A: The KB25CKG01-GG uses Solder Lug termination exclusively. The YB25WCKW01-GB offers both Solder and Quick Connect (0.110" / 2.8mm) options. Confirm your assembly process supports the selected termination method. Solder Lug compatibility exists, but Quick Connect requires appropriate receptacles.

Q: Does the substitute provide additional environmental protection?

A: Yes. The YB25WCKW01-GB includes IP65 ingress protection (Dust Tight, Water Resistant), while the KB25CKG01-GG does not specify ingress protection. This makes the substitute suitable for applications requiring enhanced environmental sealing.

Q: What is the mechanical life advantage of the substitute?

A: The YB25WCKW01-GB is rated for 1,000,000 mechanical cycles compared to the KB25CKG01-GG's 100,000 cycles. This 10-fold improvement extends component service life in high-frequency switching applications.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both parts operate within -25°C to 70°C, maintaining functional equivalence across standard industrial temperature environments.

Q: What compliance certifications apply to both parts?

A: Both KB25CKG01-GG and YB25WCKW01-GB are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, satisfying regulatory requirements for equivalent component selection in controlled manufacturing environments.
