KAS1104R Equivalent & Substitute Parts

Part Overview

The KAS1104R is a DIP switch manufactured by E-Switch, designed for through-hole PCB mounting applications requiring low-current switching at 24VDC. This SPST 4-position slide switch is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit configurations are maintained across alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAS1104R is determined by strict equivalence in the following parameters:

• Electrical Compatibility: Circuit type (SPST), current rating (25mA), and voltage rating (24VDC) must be identical
• Mechanical Compatibility: Number of positions (4), actuator type (slide standard), mounting method (through hole), pitch (0.100"), and termination style (PC pin) must match
• Environmental Compliance: RoHS3 compliance and MSL rating (1 - Unlimited) are required
• Form Factor: Through-hole mounting with standard slide actuator ensures PCB layout compatibility

The substitute part 1825006-5 (TE Connectivity ALCOSWITCH Switches) meets all mandatory electrical and mechanical criteria, enabling direct functional replacement in applications where the KAS1104R is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the KAS1104R and 1825006-5 are active products with full regulatory compliance (RoHS3, REACH Unaffected, EAR99 classification). Selection between these parts should be based on:

• Supply Availability: Current inventory levels and lead times from respective manufacturers
• Procurement Specifications: Existing design documentation and approved vendor lists
• Physical Constraints: The KAS1104R has a height of 0.236" (6.00mm) versus 1825006-5 at 0.114" (2.90mm); applications with height restrictions may require the lower-profile TE Connectivity option
• Operational Cycles: The KAS1104R supports 2,000 mechanical and electrical cycles, while 1825006-5 supports 1,000 cycles; high-cycle applications should prioritize the E-Switch part
• Environmental Sealing: The 1825006-5 includes tape seal features; applications requiring washable components should consider this option

Frequently Asked Questions (FAQ)

Q: Can the 1825006-5 be used as a direct replacement for the KAS1104R in existing designs?

A: Yes, the 1825006-5 meets all mandatory electrical and mechanical specifications (SPST, 4-position, 25mA, 24VDC, through-hole, 0.100" pitch, PC pin termination). However, physical height differences (0.236" vs. 0.114") and mechanical life ratings (2,000 vs. 1,000 cycles) must be evaluated for specific applications.

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

A: Primary differences include: height above board (KAS1104R is taller), mechanical/electrical life cycles (KAS1104R rated for 2,000 cycles vs. 1,000 for 1825006-5), operating temperature minimum (-40°C vs. -30°C), body material (PBT glass-filled vs. PPS), and washability features (1825006-5 includes tape seal).

Q: Are both parts RoHS3 compliant?

A: Yes, both the KAS1104R and 1825006-5 are ROHS3 compliant with MSL rating 1 (Unlimited) and REACH Unaffected status.

Q: Which part should be selected for high-cycle switching applications?

A: The KAS1104R is rated for 2,000 mechanical and electrical cycles, compared to 1,000 cycles for the 1825006-5. Applications requiring extended operational life should specify the KAS1104R.

Q: Does the height difference affect PCB layout compatibility?

A: The KAS1104R height of 0.236" (6.00mm) versus 1825006-5 at 0.114" (2.90mm) may impact clearance in space-constrained designs. PCB layout and enclosure dimensions must be verified before substitution.
