KAJ04TGGT Equivalent & Substitute Parts

Part Overview

The KAJ04TGGT is a 4-position surface mount DIP slide switch manufactured by E-Switch, rated for 25mA at 24VDC with SPST circuit configuration. This component features gold-plated copper alloy contacts, flush/recessed slide actuator, and gull wing termination suitable for PCB assembly. The part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production runs and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete KAJ04TGGT with the active TE Connectivity ALCOSWITCH part number 1825006-7 is based on electrical and mechanical parameter equivalence within the DIP switch product category. The substitute maintains identical specifications across critical functional parameters: SPST circuit, 4-position configuration, 25mA current rating, 24VDC voltage rating, slide actuator type with flush/recessed actuation level, copper alloy gold-plated contacts, surface mount assembly, gull wing termination, and 0.100" pitch. Both components utilize PPS body material, feature tape seal protection, and meet ROHS3 compliance and MSL 1 moisture sensitivity requirements. These aligned parameters ensure functional and mechanical interchangeability in existing PCB designs without requiring layout or schematic modifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity ALCOSWITCH 1825006-7 is the qualified substitute for the obsolete KAJ04TGGT. Selection is based on the following engineering criteria:

Electrical equivalence is established through identical SPST circuit topology, 4-position configuration, 25mA current rating, and 24VDC voltage specification. Mechanical interchangeability is confirmed by matching actuator type (slide standard), actuator level (flush/recessed), contact material and finish (copper alloy, gold-plated), mounting method (surface mount), termination style (gull wing), and pitch (0.100"). Physical dimensions show minor variations: the substitute exhibits a lower profile (0.114" versus 0.140" height) and marginally shorter length (0.394" versus 0.400"), both compatible with standard PCB layouts.

Compliance alignment includes ROHS3 certification and MSL 1 moisture sensitivity for both components, ensuring regulatory and environmental consistency. The substitute maintains active product status with established supply chain availability, addressing the obsolescence constraint of the original part.

Operating temperature range for the substitute (-30°C to 85°C) encompasses the majority of industrial applications, though designs requiring the full -40°C lower limit of the original part require thermal analysis. Mechanical and electrical life ratings of 1,000 cycles for the substitute remain adequate for standard switching applications, though designs dependent on the original 2,000-cycle specification require operational profile assessment.

Frequently Asked Questions (FAQ)

Q: Can the 1825006-7 be used as a direct replacement in existing PCB designs?

A: Yes. The substitute maintains identical electrical ratings (25mA, 24VDC, SPST), circuit configuration (4-position), actuator type (slide standard), contact specifications (copper alloy, gold-plated), mounting method (surface mount), termination style (gull wing), and pitch (0.100"). Physical dimensions are compatible with standard PCB layouts. No schematic or layout modifications are required.

Q: What are the dimensional differences between the KAJ04TGGT and 1825006-7?

A: The substitute is lower profile (0.114" versus 0.140" height above board) and marginally shorter (0.394" versus 0.400" length). These differences are negligible for standard PCB assembly and do not affect component placement or clearance in typical designs.

Q: Are there temperature range limitations with the substitute?

A: The substitute operates from -30°C to 85°C, compared to the original part's -40°C to 85°C range. For applications requiring operation below -30°C, thermal performance analysis is necessary to confirm suitability.

Q: How do the mechanical and electrical life ratings compare?

A: The substitute is rated for 1,000 mechanical and electrical cycles, while the original part is rated for 2,000 cycles. For applications with switching cycles exceeding 1,000 operations, operational profile assessment is required to confirm adequacy.

Q: What is the packaging format for the substitute part?

A: The 1825006-7 is supplied in tube packaging, suitable for automated pick-and-place assembly and standard component handling procedures.

Q: Are both parts RoHS and MSL compliant?

A: Yes. Both the KAJ04TGGT and 1825006-7 meet ROHS3 compliance and carry MSL 1 (Unlimited) moisture sensitivity classification, ensuring regulatory and environmental consistency.

Q: What is the supply status difference between these parts?

A: The KAJ04TGGT is classified as obsolete with limited remaining inventory (914 pieces). The 1825006-7 is an active product with established supply availability (12,309 pieces in stock), ensuring long-term procurement reliability for production and support applications.
