KAJ06TAGT Equivalent & Substitute Parts

Part Overview

The KAJ06TAGT is a 6-position DIP slide switch manufactured by E-Switch, rated for 25mA at 24VDC with SPST (Single Pole Single Throw) circuit configuration. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The switch features through-hole mounting with PC pin termination, gold-plated copper alloy contacts, and is suitable for applications requiring low-current switching in industrial and consumer electronics.

Substitute Part Grouping Explanation

Substitution eligibility for the KAJ06TAGT is determined by the following critical parameters:

Primary Compatibility Criteria:

Circuit configuration: SPST (mandatory match)
Number of positions: 6 (mandatory match)
Mounting type: Through Hole (mandatory match)
Termination style: PC Pin (mandatory match)
Pitch: 0.100" (2.54mm) (mandatory match)
Actuator type: Slide (Standard) (mandatory match)

Secondary Compatibility Criteria (allowable variance):

Current rating: Must equal or exceed 25mA
Voltage rating: Must equal or exceed 24VDC
Operating temperature range: Must encompass or exceed -40°C ~ 85°C
Contact material and finish: Copper alloy or beryllium copper with gold finish acceptable
RoHS and regulatory compliance: ROHS3 compliant required

All three substitute parts meet these criteria with higher current and voltage ratings, providing enhanced electrical performance margins.

Engineering Selection Recommendations

1825006-9 (TE Connectivity ALCOSWITCH): This part provides the closest electrical match to the KAJ06TAGT with identical current (25mA) and voltage (24VDC) ratings. Product status is active with full manufacturing support. Operating temperature range is -30°C ~ 85°C, which covers the upper portion of the original specification. ROHS3 compliance and unlimited MSL rating ensure regulatory alignment. Height above board is reduced to 0.114" compared to the original 0.142", which may require PCB layout verification for clearance-sensitive applications.

SD06H0B (C&K): This substitute offers enhanced electrical performance with 100mA current rating and 25VDC voltage rating, exceeding the original 25mA/24VDC specification. Operating temperature range matches the original at -40°C ~ 85°C. Product status is active with established supply chain. Mechanical and electrical life ratings are 2,000 cycles, matching the original. Height above board is 0.178", requiring PCB layout consideration.

209-6LPST (CTS Electrocomponents): This part provides the highest current rating at 100mA but operates at 20VDC, which is below the original 24VDC specification. Operating temperature range matches at -40°C ~ 85°C. Product status is active. This option is suitable only for applications where the 20VDC rating is acceptable and current headroom is prioritized. Height above board is 0.180", the tallest of the three substitutes.

Frequently Asked Questions (FAQ)

Q: Can the 1825006-9 replace the KAJ06TAGT in all applications?

A: The 1825006-9 is electrically compatible for applications operating at 24VDC with loads up to 25mA. The reduced operating temperature minimum of -30°C (versus -40°C) must be evaluated for cold-environment applications. PCB layout clearance should be verified due to the reduced height of 0.114" compared to the original 0.142".

Q: Is the SD06H0B suitable for 24VDC applications?

A: Yes. The SD06H0B is rated for 25VDC, which exceeds the 24VDC requirement. The 100mA current rating provides additional margin beyond the 25mA requirement. Operating temperature range and mechanical life match the original specification.

Q: Why does the 209-6LPST have a lower voltage rating than the original?

A: The 209-6LPST is rated for 20VDC, which is below the original 24VDC specification. This part is not recommended as a direct substitute for applications requiring 24VDC operation. Use only if circuit voltage can be confirmed at 20VDC or lower.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification, matching the original KAJ06TAGT. All are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the impact of different contact materials on substitution?

A: The original KAJ06TAGT uses copper alloy contacts. The SD06H0B and 209-6LPST use beryllium copper contacts, which offer superior electrical and mechanical performance. Both materials are gold-plated and suitable for low-current switching applications. Contact material change does not affect functional compatibility.

Q: Are there packaging differences between substitutes?

A: All substitutes are supplied in tube packaging. The original part number does not specify packaging format. Tube packaging is standard for DIP switch distribution and does not affect component functionality or PCB assembly compatibility.
