KP0115ANBKG03CF-3JB Equivalent & Substitute Parts

Part Overview

The KP0115ANBKG03CF-3JB is a pushbutton switch manufactured by NKK Switches, classified as SPST-NO (Single Pole Single Throw - Normally Open) with illumination capability. This through-hole mounted component operates at 12V DC with a 100mA current rating and features a square button actuator with LED illumination in green/red. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KP0115ANBKG03CF-3JB is determined by strict equivalence across the following critical parameters:

Circuit and Electrical Function: The substitute must maintain SPST-NO configuration with identical switch function (Off-Mom) and matching DC voltage rating of 12V and current rating of 100mA.

Illumination Specifications: LED illumination type with green/red color capability is required. Illumination voltage must be compatible within the specified range (2.1–4.6 VDC nominal).

Physical and Mounting Characteristics: Through-hole mounting type with PC pin termination style and square button actuator type must be preserved for mechanical compatibility with existing PCB layouts.

Environmental and Reliability Parameters: Operating temperature range, mechanical life, and electrical life specifications define the performance envelope for equivalent operation.

The LP11OA1NCSRG from E-Switch meets these substitution criteria across all critical parameters while maintaining functional equivalence for the obsolete KP0115ANBKG03CF-3JB.

Parameter Comparison

Engineering Selection Recommendations

The LP11OA1NCSRG from E-Switch is a functional equivalent for the obsolete KP0115ANBKG03CF-3JB based on matching electrical specifications, circuit configuration, and physical mounting characteristics. The substitute part is currently in active production status, ensuring availability for replacement and new design applications.

The LP11OA1NCSRG provides superior operating temperature range (-20°C to 70°C versus -25°C to 50°C), expanding environmental capability. However, mechanical and electrical life ratings are lower (1,000,000 cycles versus 5,000,000 cycles). This difference must be evaluated against application duty cycle requirements.

The substitute part carries ROHS3 compliance certification, meeting current regulatory requirements. Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS coding, confirming regulatory equivalence.

Illumination voltage specifications are compatible, with the substitute operating at 2.2 and 4.6 VDC nominal versus 2.1 and 4.6 VDC for the original part. This minor variance remains within acceptable tolerance for LED illumination circuits.

Frequently Asked Questions (FAQ)

Q: Can the LP11OA1NCSRG directly replace the KP0115ANBKG03CF-3JB in existing designs?

A: Yes, the LP11OA1NCSRG is a direct functional equivalent. Both parts share identical SPST-NO circuit configuration, 12V DC voltage rating, 100mA current rating, through-hole mounting, PC pin termination, and LED illumination specifications. Physical dimensions and pin configurations are compatible for PCB layout substitution.

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

A: The primary differences are mechanical and electrical life ratings (LP11OA1NCSRG: 1,000,000 cycles versus KP0115ANBKG03CF-3JB: 5,000,000 cycles) and operating temperature range (LP11OA1NCSRG: -20°C to 70°C versus KP0115ANBKG03CF-3JB: -25°C to 50°C). The substitute part offers wider temperature capability but lower cycle life. Product status differs, with the substitute currently in active production.

Q: Are there packaging differences between the main part and substitute?

A: The KP0115ANBKG03CF-3JB is specified with dash packaging notation, while the LP11OA1NCSRG is supplied in bulk packaging. Both maintain identical component specifications and through-hole mounting requirements. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the illumination voltage compatibility between these parts?

A: Both parts operate with LED illumination at compatible voltage levels. The KP0115ANBKG03CF-3JB operates at 2.1 and 4.6 VDC nominal, while the LP11OA1NCSRG operates at 2.2 and 4.6 VDC nominal. This 0.1V variance at the lower voltage point is within standard LED circuit tolerance and does not affect functional compatibility.

Q: Is the LP11OA1NCSRG suitable for applications requiring 5,000,000 cycle life?

A: The LP11OA1NCSRG is rated for 1,000,000 mechanical and electrical cycles, which is lower than the original part's 5,000,000 cycle rating. Applications with high duty cycle requirements must evaluate whether the reduced cycle life meets operational demands. For lower-duty applications, the substitute is fully suitable.

Q: What regulatory certifications apply to the substitute part?

A: The LP11OA1NCSRG carries ROHS3 compliance certification and maintains REACH Unaffected status, identical to the original part. Both components share the same ECCN (EAR99) and HTSUS (8536.50.9031) classifications, confirming regulatory equivalence for import, export, and environmental compliance purposes.
