KAJ02TGGR Equivalent & Substitute Parts

Part Overview

The KAJ02TGGR is a DIP slide switch manufactured by E-Switch, configured as a single-pole single-throw (SPST) switch with 2 positions, rated for 25mA at 24VDC. This component features surface mount gull wing termination with gold-plated copper alloy contacts and is designed for applications requiring reliable switching in compact form factors.

The KAJ02TGGR is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production, repair, and field replacement applications.

Substitute Part Grouping Explanation

Substitute parts for the KAJ02TGGR are qualified based on electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Electrical Parameters (Critical):

Circuit configuration: SPST
Number of positions: 2
Current rating: 25mA
Voltage rating: 24VDC
Contact material: Copper Alloy
Contact finish: Gold

Mechanical Parameters (Critical):

Actuator type: Slide (Standard)
Actuator level: Flush, Recessed
Mounting type: Surface Mount
Termination style: Gull Wing
Pitch: 0.100" (2.54mm)

Compliance Parameters:

RoHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed below meet these core requirements. Variations in physical dimensions (height above board, length), operating temperature range, body material composition, and packaging format do not affect functional substitutability within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

All three substitute parts—DMR02, DMR02T, and DMR02TTR—are manufactured by APEM Inc. and maintain active product status. Each part satisfies the electrical and mechanical requirements for direct substitution with the obsolete KAJ02TGGR.

DMR02 (Tube Packaging): Suitable for applications requiring standard tube packaging. Inventory availability is 991 pieces.

DMR02T (Tube Packaging with Tape Seal): Includes tape seal feature for enhanced protection during storage and transport. Inventory availability is 2,132 pieces.

DMR02TTR (Tape & Reel Packaging with Tape Seal): Optimized for high-volume automated assembly processes. Tape & reel format enables direct integration with pick-and-place equipment. Inventory availability is 6,142 pieces.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection between these three options should be based on packaging requirements and production methodology rather than electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can DMR02, DMR02T, and DMR02TTR be used interchangeably with KAJ02TGGR?

A: Yes. All three parts meet the core electrical and mechanical specifications: SPST circuit, 2 positions, 25mA at 24VDC, slide actuator, flush/recessed level, gold-plated copper alloy contacts, surface mount gull wing termination, and 0.100" pitch. Functional performance is equivalent.

Q: What is the difference between DMR02, DMR02T, and DMR02TTR?

A: The primary differences are packaging format and tape seal feature. DMR02 is supplied in tube packaging without tape seal. DMR02T is supplied in tube packaging with tape seal protection. DMR02TTR is supplied in tape & reel format with tape seal protection, designed for automated assembly. All three are electrically and mechanically identical.

Q: Which substitute part should be selected for automated assembly?

A: DMR02TTR is recommended for automated pick-and-place assembly due to its tape & reel packaging format. This format integrates directly with standard SMT equipment and reduces manual handling.

Q: Are there any temperature range differences between the main part and substitutes?

A: The KAJ02TGGR operates from -40°C to 85°C. The APEM Inc. substitutes (DMR02, DMR02T, DMR02TTR) operate from -20°C to 85°C. If the application requires operation below -20°C, the KAJ02TGGR specification must be maintained.

Q: Do all parts meet current compliance standards?

A: Yes. All parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the mechanical life rating for these switches?

A: All parts, including the main part and substitutes, are rated for 2,000 mechanical cycles and 2,000 electrical cycles.
