Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K12CF21.5OD is determined by strict alignment of the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 100mA DC minimum
• Voltage rating: 30V DC minimum
• Mounting type: Through Hole
• Actuator type: Round button with rubber cap
• Termination style: PC Pin
• Ingress protection: IP67 or equivalent
• Operating temperature range: -40°C to 85°C or broader
• Tactile feedback requirement: Present

The K12C 1 5N meets all specified parameters and belongs to the same K12 series, confirming direct substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

The K12C 1 5N is the direct substitute for the K12CF21.5OD. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the K12CF21.5OD is obsolete, while the K12C 1 5N maintains active production status.

From a compliance perspective, both parts are RoHS compliant. The K12C 1 5N carries ROHS3 certification, representing current regulatory alignment. The K12C 1 5N is available in bulk packaging with significantly higher inventory levels (19,604 units in stock versus 1,009 units for the obsolete part), ensuring supply chain continuity for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the K12C 1 5N directly replace the K12CF21.5OD in existing designs?

A: Yes. Both components are electrically and mechanically identical across all specified parameters, including circuit configuration, current and voltage ratings, actuator type, termination style, and ingress protection rating. Direct substitution is supported without design modification.

Q: What is the primary reason to transition from K12CF21.5OD to K12C 1 5N?

A: The K12CF21.5OD is obsolete. The K12C 1 5N is an active product with reliable supply availability and current regulatory compliance (ROHS3). Transitioning to the active part ensures long-term component availability and manufacturing continuity.

Q: Are there packaging differences between these parts?

A: The K12CF21.5OD is supplied with standard packaging, while the K12C 1 5N is available in bulk packaging. Both configurations support the same component specifications and performance characteristics.

Q: Do both parts meet the same environmental and operational requirements?

A: Yes. Both components operate across the identical temperature range (-40°C to 85°C), maintain IP67 ingress protection, and provide tactile feedback. Moisture sensitivity levels are equivalent at MSL 1 (Unlimited).

Q: Is there any difference in electrical life or cycle rating?

A: The K12CF21.5OD specifies 1,000,000 electrical life cycles. The K12C 1 5N does not list this parameter in the provided data. For applications where electrical life specification is critical, direct confirmation with the manufacturer is advised.
