K6SLWH1.55NLV302SD Equivalent & Substitute Parts

Part Overview

The K6SLWH1.55NLV302SD is a pushbutton switch manufactured by C&K, classified as a SPST-NO (Single Pole Single Throw - Normally Open) keyswitch with illumination. This surface mount component is rated for 0.1A at 30V DC and features white LED illumination with tactile feedback. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the K6SLWH1.55NLV302SD is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Switch Function: Off-Mom (momentary) operation required
• Current Rating: 100mA DC minimum
• Voltage Rating: 30V DC minimum
• Mounting Type: Surface Mount required
• Illumination: LED, White color
• Operating Temperature: -40°C to 85°C range
• Environmental Compliance: RoHS and REACH status

The substitute part 14AP-L1-02-W (Grayhill Inc.) meets all critical electrical and mechanical parameters. While differences exist in actuator type, termination style, and mechanical life rating, these variations do not prevent functional substitution when the core electrical and operational requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The 14AP-L1-02-W from Grayhill Inc. is a direct functional substitute for the obsolete K6SLWH1.55NLV302SD. Both components satisfy identical electrical specifications: SPST-NO circuit, 100mA DC current rating, 30V DC voltage rating, and white LED illumination across the -40°C to 85°C operating range.

The substitute part offers enhanced product status (Active vs. Obsolete), ensuring long-term availability and supply chain stability. The 14AP-L1-02-W demonstrates superior environmental compliance with ROHS3 certification and provides extended electrical life (200,000 cycles vs. 100,000 cycles), representing improved reliability margins for equivalent electrical performance.

Both components maintain identical moisture sensitivity classification (MSL 1) and REACH compliance status, confirming compatibility with existing regulatory and manufacturing requirements.

Frequently Asked Questions (FAQ)

Q: Can the 14AP-L1-02-W directly replace the K6SLWH1.55NLV302SD in existing designs?

A: Yes. Both components share identical electrical specifications (SPST-NO, 100mA DC, 30V DC), illumination characteristics (LED, White), and operating temperature range (-40°C to 85°C). Surface mount mounting type is consistent. Physical footprint compatibility must be confirmed through PCB layout review, as actuator type and termination style differ between manufacturers.

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

A: The primary differences are: (1) Actuator type—K6 uses plunger for cap; 14AP uses round button; (2) Termination style—K6 uses gull wing; 14AP uses SMD tab; (3) Electrical life—K6 rated for 100,000 cycles; 14AP rated for 200,000 cycles; (4) Product status—K6 is obsolete; 14AP is active.

Q: Are there packaging differences?

A: Yes. The K6SLWH1.55NLV302SD is supplied in standard packaging, while the 14AP-L1-02-W is supplied in Tape & Reel (TR) format. This affects procurement and assembly processes but does not impact electrical or functional performance.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both components are RoHS compliant and REACH unaffected. The 14AP-L1-02-W carries ROHS3 certification, representing the current standard revision.

Q: What is the illumination voltage requirement for the 14AP-L1-02-W?

A: The 14AP-L1-02-W specifies 2.85 VDC nominal illumination voltage. This parameter was not provided for the K6SLWH1.55NLV302SD. Circuit design must accommodate this specification when implementing the substitute part.
