KAJ10LGGT DIP Switch Equivalent & Substitute Parts

Part Overview

The KAJ10LGGT is a 10-position surface mount DIP switch manufactured by E-Switch, designed for SPST (Single Pole Single Throw) switching applications at 24VDC with a 25mA current rating. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing production support and design updates. The switch features a standard slide actuator with gold-plated copper alloy contacts and is suitable for applications requiring low-current DC switching with a mechanical and electrical life rating of 2,000 cycles.

Key Parameters

Substitute Part Grouping Explanation

The SD12H0SB from C&K is identified as a manufacturer-recommended substitute for the KAJ10LGGT. Substitution compatibility is determined by the following critical parameters:

Electrical Compatibility:

• Both parts operate as SPST switches with identical circuit configuration
• The SD12H0SB voltage rating of 25VDC exceeds the KAJ10LGGT requirement of 24VDC, providing adequate margin
• The SD12H0SB current rating of 100mA exceeds the KAJ10LGGT requirement of 25mA, ensuring sufficient capacity for the same applications

Mechanical Compatibility:

• Both parts use surface mount technology with gull wing termination
• Both parts maintain 0.100" (2.54mm) pitch spacing, ensuring PCB footprint compatibility
• Both parts feature standard slide actuators with identical operating temperature range (-40°C ~ 85°C)
• Both parts achieve 2,000 cycles mechanical and electrical life rating

Regulatory Compliance:

• Both parts are ROHS3 compliant and REACH unaffected
• Both parts carry identical ECCN and HTSUS classifications

Functional Differences: The SD12H0SB provides 12 positions compared to the KAJ10LGGT's 10 positions. This difference does not prevent substitution; the additional positions simply provide expanded configuration options. The SD12H0SB is currently in active production status, whereas the KAJ10LGGT is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The SD12H0SB is suitable as a direct substitute for the KAJ10LGGT based on the following engineering criteria:

Electrical Performance: The SD12H0SB exceeds the electrical requirements of the KAJ10LGGT with higher current and voltage ratings, ensuring safe operation in applications designed for the original part.

Physical Integration: Both parts maintain identical pitch spacing and surface mount gull wing termination, allowing direct PCB footprint compatibility. The minimal height difference (0.007" / 0.18mm) is negligible for most applications.

Regulatory Compliance: Both parts meet ROHS3 compliance and carry identical trade classification codes, ensuring regulatory continuity in production environments.

Production Availability: The SD12H0SB is in active production status, providing long-term supply chain security compared to the obsolete KAJ10LGGT.

Functional Capacity: The SD12H0SB's 12-position configuration accommodates all 10-position applications of the original part, with additional configuration flexibility.

Frequently Asked Questions (FAQ)

Q: Can the SD12H0SB directly replace the KAJ10LGGT on existing PCBs?

A: Yes. Both parts share identical pitch spacing (0.100" / 2.54mm), gull wing termination, and surface mount footprint. The height difference of 0.007" (0.18mm) is within standard PCB assembly tolerances.

Q: Are there electrical differences that affect circuit operation?

A: The SD12H0SB has higher electrical ratings (100mA at 25VDC versus 25mA at 24VDC). This provides additional capacity margin and does not negatively affect circuits designed for the lower-rated KAJ10LGGT.

Q: What is the significance of the position count difference (10 vs. 12)?

A: The SD12H0SB provides two additional switch positions. Applications using only 10 positions will function identically; the extra positions remain available for future configuration changes without requiring component replacement.

Q: Does the actuator level difference (Raised vs. Flush/Recessed) affect compatibility?

A: The actuator level difference reflects physical profile variation. Both actuator types are standard slide mechanisms. Verify that the enclosure or access panel design accommodates the SD12H0SB's flush/recessed actuator profile.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -40°C to 85°C, providing identical thermal performance.

Q: What packaging format is the SD12H0SB supplied in?

A: The SD12H0SB is supplied in tube packaging, compared to the KAJ10LGGT's standard packaging. Verify that tube packaging is compatible with your assembly process.
