Key Parameters

Substitute Part Grouping Explanation

Substitution of the KSL0M312 is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST-NO)
• Switch function (Off-Mom momentary operation)
• Contact rating (0.05A @ 32VDC)
• Mounting type (Through Hole)
• Actuator orientation (Top Actuated)
• Physical dimensions (7.40mm x 7.40mm outline, 9.90mm actuator height)
• Mechanical characteristics (130gf operating force, 0.50mm travel, 1,000,000 cycle life)
• Environmental rating (IP65 ingress protection)
• Operating temperature range (-40°C ~ 90°C)
• Termination style (PC Pin)
• Series compatibility (KSL MKII)

The KSL0M312LFT meets all these parameters and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging configuration.

Engineering Selection Recommendations

The KSL0M312LFT is the direct substitute for the obsolete KSL0M312. Both components are electrically and mechanically identical across all functional parameters.

Selection between these parts should be based on the following factors:

Product Status: The KSL0M312 is obsolete, while the KSL0M312LFT maintains active product status with higher inventory availability (11,032 pcs vs. 1,096 pcs). For new designs or ongoing production, the KSL0M312LFT is the appropriate choice.

Regulatory Compliance: The KSL0M312LFT is ROHS3 compliant, whereas the KSL0M312 is RoHS non-compliant. Applications subject to RoHS regulations require the KSL0M312LFT.

Packaging: The KSL0M312 is supplied in standard packaging, while the KSL0M312LFT is supplied in bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Both parts share identical electrical ratings, mechanical characteristics, environmental protection ratings, and temperature operating ranges, ensuring functional interchangeability in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the KSL0M312LFT be used as a direct replacement for the KSL0M312?

A: Yes. The KSL0M312LFT is a direct substitute. Both components share identical electrical specifications (0.05A @ 32VDC SPST-NO), mechanical characteristics (130gf operating force, 0.50mm travel, 1,000,000 cycle life), physical dimensions (7.40mm x 7.40mm outline, 9.90mm actuator height), and environmental ratings (IP65 ingress protection, -40°C ~ 90°C operating temperature). No circuit redesign or PCB layout modification is required.

Q: What are the key differences between KSL0M312 and KSL0M312LFT?

A: The primary differences are product status, RoHS compliance, and packaging. The KSL0M312 is obsolete and RoHS non-compliant, while the KSL0M312LFT is active and ROHS3 compliant. The KSL0M312LFT is supplied in bulk packaging with significantly higher inventory availability.

Q: Are there any compatibility concerns with PCB footprints?

A: No. Both components use identical through-hole PC pin termination, share the same 7.40mm x 7.40mm outline dimensions, and maintain the same 9.90mm actuator height off PCB. Existing PCB designs require no modification.

Q: Which part should be selected for new designs?

A: The KSL0M312LFT should be selected for new designs. It maintains active product status, offers superior supply chain availability, and meets current RoHS3 regulatory requirements.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints during storage or handling.
