Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K5V19023P is determined by strict adherence to the following core electrical and mechanical parameters:

Critical Matching Parameters (Non-Negotiable):

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Contact rating: 0.1A @ 32VDC
• Mounting type: Panel Mount
• Actuator orientation: Top Actuated
• Termination style: Solder Lug
• Outline dimensions: 9.70mm x 8.50mm
• Switch travel: 1.20mm
• Operating temperature range: -40°C ~ 85°C
• Ingress protection: IP40

Allowable Variation Parameters:

• Actuator type (Round Button vs. Translucent)
• Operating force (200gf vs. 400gf)
• Illumination capability (Non-Illuminated vs. Illuminated with LED)
• Product status (Obsolete vs. Active)
• RoHS certification level (RoHS Compliant vs. ROHS3 Compliant)

The K5V1YG43P qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering enhanced features through illumination and higher operating force, with improved product status and compliance certifications.

Engineering Selection Recommendations

K5V1YG43P as Primary Substitute:

The K5V1YG43P is the qualified substitute for the obsolete K5V19023P. Selection of this part is supported by the following engineering criteria:

1. Product Status: The K5V1YG43P maintains Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete K5V19023P.

2. Regulatory Compliance: The K5V1YG43P carries ROHS3 Compliant certification, representing enhanced compliance over the RoHS Compliant designation of the original part. Both parts maintain REACH Unaffected status.

3. Electrical Equivalence: All critical electrical parameters are identical, including SPDT circuit configuration, 0.1A @ 32VDC contact rating, and momentary switch function.

4. Mechanical Compatibility: Physical dimensions, mounting configuration, termination style, and actuator orientation are fully matched, ensuring direct mechanical substitution in panel-mount applications.

5. Environmental Performance: Operating temperature range (-40°C ~ 85°C), ingress protection (IP40), and moisture sensitivity level (MSL 1) are maintained.

Design Considerations:

The K5V1YG43P incorporates illumination capability (LED, Green/Yellow) and increased operating force (400gf vs. 200gf). These enhancements do not compromise substitution eligibility but represent functional upgrades. Applications requiring the original non-illuminated configuration or lower actuation force must evaluate whether these variations impact circuit design or user interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the K5V1YG43P directly replace the K5V19023P in existing designs?

A: Yes. The K5V1YG43P maintains all critical electrical and mechanical parameters required for direct substitution. Physical dimensions, mounting configuration, circuit topology, and contact ratings are identical. The illumination feature and increased operating force represent functional enhancements that do not prevent mechanical or electrical compatibility.

Q: What is the difference in operating force between these parts?

A: The K5V19023P requires 200gf (gram-force) of actuator pressure, while the K5V1YG43P requires 400gf. This difference affects tactile feedback and user interface feel but does not impact electrical performance or circuit compatibility. Applications with specific actuation force requirements must evaluate this parameter against design specifications.

Q: Does the illumination feature of the K5V1YG43P require additional circuit modifications?

A: The illumination feature is integrated into the K5V1YG43P design. Applications not requiring illumination can operate the part without activating the LED function. However, circuit design must accommodate the illumination capability if the LED feature is to be utilized.

Q: Are the outline dimensions and mounting footprints identical?

A: Yes. Both parts share identical outline dimensions (9.70mm x 8.50mm) and panel-mount configuration with solder lug termination. PCB layout and mechanical mounting requirements are fully compatible.

Q: What is the significance of the product status change from Obsolete to Active?

A: The K5V1YG43P's Active status indicates current manufacturing and ongoing availability from C&K. This ensures supply chain continuity and eliminates the risk of end-of-life discontinuation associated with the Obsolete K5V19023P.

Q: Are both parts RoHS compliant?

A: Yes. The K5V19023P is RoHS Compliant, and the K5V1YG43P is ROHS3 Compliant. Both certifications satisfy RoHS directive requirements. The ROHS3 designation represents the current regulatory standard and indicates enhanced compliance documentation.

Q: What is the mechanical life expectancy for both parts?

A: Both the K5V19023P and K5V1YG43P are rated for 25,000 mechanical cycles, providing equivalent durability and reliability for momentary switch applications.
