K6B 1.5 5N Equivalent & Substitute Parts

Part Overview

The K6B 1.5 5N is a pushbutton switch manufactured by C&K, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a keyswitch type actuator. This component is rated for 0.1A at 30V DC and features tactile feedback with a plunger actuator. The part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the K6B 1.5 5N is determined by the following critical parameters:

• Circuit Configuration: Both main and substitute parts must maintain SPST-NO topology
• Switch Function: Off-Mom (momentary) operation must be preserved
• Actuator Type: Plunger for cap configuration required for mechanical compatibility
• Termination Style: PC Pin termination for PCB mounting compatibility
• Current Rating: Minimum 100mA capacity at rated voltage
• Voltage Rating: Substitute must support the operating voltage of the application
• Mounting Type: Through Hole configuration for board integration
• Electrical Life: Minimum 200,000 cycles for operational durability

The MDPSLFS substitute meets these core substitution criteria while offering enhanced voltage rating and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MDPSLFS is a direct functional substitute for the K6B 1.5 5N based on matching circuit topology, switch function, actuator configuration, and termination style. Key considerations for selection:

Voltage Capability: The MDPSLFS provides 100V DC rating compared to the K6B 1.5 5N's 30V DC rating. This higher voltage specification ensures compatibility with applications operating at or below 30V DC without derating.

Product Status: The MDPSLFS maintains active product status with current manufacturing support, addressing the obsolescence of the K6B 1.5 5N. This ensures long-term availability and supply chain continuity.

Compliance: Both components are RoHS compliant. The MDPSLFS carries ROHS3 certification, meeting current regulatory requirements. Both are REACH Unaffected and classified as EAR99.

Operating Temperature: The K6B 1.5 5N operates across -40°C to 85°C, while the MDPSLFS operates across -25°C to 70°C. Applications requiring the full -40°C lower temperature range of the original part should be evaluated for thermal compatibility.

Current and Electrical Life: Both components support 100mA operation with 200,000 cycle electrical life, ensuring equivalent switching performance.

Frequently Asked Questions (FAQ)

Q: Can the MDPSLFS directly replace the K6B 1.5 5N in existing designs?

A: The MDPSLFS is functionally compatible as a substitute. Both components share identical circuit topology (SPST-NO), switch function (Off-Mom), actuator type (plunger for cap), and termination style (PC Pin). Verify that your application's operating temperature range falls within -25°C to 70°C and that the 100V DC rating of the MDPSLFS is acceptable for your circuit.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (K6B 1.5 5N: 30V DC; MDPSLFS: 100V DC), operating temperature range (K6B 1.5 5N: -40°C to 85°C; MDPSLFS: -25°C to 70°C), product status (K6B 1.5 5N: Obsolete; MDPSLFS: Active), and packaging (K6B 1.5 5N: standard; MDPSLFS: Tray). Both maintain identical electrical life and current ratings.

Q: Are there packaging considerations when switching to the MDPSLFS?

A: The MDPSLFS is supplied in Tray packaging, whereas the K6B 1.5 5N uses standard packaging. Verify that tray packaging is compatible with your assembly and handling processes.

Q: What compliance certifications apply to the MDPSLFS?

A: The MDPSLFS is ROHS3 Compliant, REACH Unaffected, and classified as EAR99. These certifications align with current regulatory requirements for electronic components.

Q: If my application requires the full -40°C lower temperature range, what should I do?

A: The MDPSLFS operates to -25°C minimum. If your application requires operation below -25°C, the K6B 1.5 5N's extended temperature range may be necessary. Consult with C&K for alternative active products supporting the full -40°C to 85°C range.
