D6L90 LFS Equivalent & Substitute Parts

Part Overview

The D6L90 LFS 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 32V DC and features tactile feedback with a plunger actuator. The D6L90 LFS is currently listed as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

The D6L90 F1 LFS qualifies as a direct substitute for the D6L90 LFS based on the following critical parameters:

• Electrical Specifications: Identical current rating (100mA DC), voltage rating (32V DC), and circuit configuration (SPST-NO)
• Mechanical Compatibility: Matching mounting type (Through Hole), actuator type (Plunger for Cap), and termination style (PC Pin)
• Environmental Performance: Identical operating temperature range (-20°C to 85°C) and electrical life rating (250,000 cycles)
• Regulatory Compliance: Both parts maintain RoHS compliance, REACH unaffected status, and MSL 1 rating
• Series Continuity: Both components belong to the C&K D6 series

The primary distinction is product status: D6L90 LFS is obsolete, while D6L90 F1 LFS is active. The D6L90 F1 LFS represents the current production equivalent with expanded inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The D6L90 F1 LFS is the appropriate selection for new designs and procurement activities. This part maintains full electrical and mechanical compatibility with the obsolete D6L90 LFS while offering the advantage of active product status and established supply chain availability. The D6L90 F1 LFS carries ROHS3 compliance, representing current regulatory alignment. Both parts satisfy identical functional requirements for SPST-NO momentary switch applications within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can D6L90 F1 LFS be used as a direct replacement for D6L90 LFS in existing designs?

A: Yes. The D6L90 F1 LFS provides direct functional and mechanical compatibility. All critical electrical parameters, mounting specifications, and environmental ratings are identical. The primary difference is product status and packaging format.

Q: What is the significance of the packaging difference between these parts?

A: D6L90 LFS is supplied in bulk packaging, while D6L90 F1 LFS is supplied in tray packaging. This distinction affects handling and storage procedures but does not impact component performance or electrical characteristics.

Q: Why is the D6L90 LFS listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. The D6L90 F1 LFS serves as the current production equivalent within the D6 series.

Q: Are there any compliance differences between these parts?

A: Both parts maintain RoHS compliance and REACH unaffected status. The D6L90 F1 LFS carries ROHS3 designation, reflecting current regulatory standards. Both parts maintain MSL 1 rating.

Q: What electrical parameters determine substitution eligibility for this switch?

A: Substitution is based on matching circuit configuration (SPST-NO), current rating (100mA DC), voltage rating (32V DC), and switch function (Off-Mom momentary operation).
