Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KP0115ACBKG03CF-3JB is determined by the following critical parameters:

• Circuit configuration must be SPST-NO
• Current rating must support minimum 100mA at DC
• Voltage rating must support 12V DC operation
• Mounting type must be Through Hole
• Actuator type must be Square, Button
• Illumination must be LED with Green/Red capability
• Termination style must be PC Pin
• Switch function must be Off-Mom (Momentary)

The substitute part LP11OA1TCSRG from E-Switch meets all these criteria, enabling direct functional replacement in applications requiring this switch configuration.

Engineering Selection Recommendations

The LP11OA1TCSRG from E-Switch serves as a direct functional equivalent for the obsolete KP0115ACBKG03CF-3JB. Selection between these parts should be based on the following factors:

For new designs or long-term applications: The LP11OA1TCSRG is the preferred choice due to its active product status, ensuring ongoing availability and manufacturer support. The component is ROHS3 compliant, meeting current environmental and regulatory requirements.

For legacy system maintenance: The LP11OA1TCSRG provides electrical and mechanical compatibility with existing circuit designs. The illumination voltage specification (2.2, 4.6 VDC) is compatible with the original part's requirement (2.1, 4.6 VDC).

Operational considerations: The E-Switch substitute offers an extended operating temperature range (-20°C ~ 70°C versus -25°C ~ 50°C), providing greater thermal flexibility. However, the mechanical and electrical life ratings are lower (1,000,000 cycles versus 5,000,000 cycles), which should be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the LP11OA1TCSRG directly replace the KP0115ACBKG03CF-3JB without circuit modifications?

A: Yes. Both components share identical electrical specifications (SPST-NO, 100mA, 12V DC), matching actuator geometry (square button), identical termination style (PC Pin), and compatible illumination characteristics (LED, Green/Red). No circuit redesign is required.

Q: What is the difference in illumination voltage between these parts?

A: The KP0115ACBKG03CF-3JB operates at 2.1 and 4.6 VDC, while the LP11OA1TCSRG operates at 2.2 and 4.6 VDC. This 0.1V variance at the lower threshold is within typical LED operating tolerances and does not affect functional compatibility.

Q: Why does the E-Switch part have lower mechanical and electrical life ratings?

A: The KP0115ACBKG03CF-3JB is rated for 5,000,000 cycles, while the LP11OA1TCSRG is rated for 1,000,000 cycles. Applications requiring high-cycle operation should evaluate whether the substitute's cycle rating meets specific duty cycle requirements.

Q: Is the LP11OA1TCSRG suitable for new product designs?

A: Yes. The LP11OA1TCSRG is an active product with ROHS3 compliance, making it appropriate for new designs. The extended operating temperature range (-20°C ~ 70°C) provides additional thermal margin compared to the obsolete KP0115ACBKG03CF-3JB.

Q: Are there packaging differences between these parts?

A: The KP0115ACBKG03CF-3JB is supplied in standard packaging, while the LP11OA1TCSRG is supplied in bulk packaging. Both use identical Through Hole mounting and PC Pin termination, ensuring mechanical compatibility on printed circuit boards.

Q: What compliance certifications apply to the substitute part?

A: The LP11OA1TCSRG is ROHS3 compliant and carries REACH Unaffected status, matching the regulatory classification of the original part (REACH Unaffected, ECCN EAR99).
