KAJ09TGGR Equivalent & Substitute Parts

Part Overview

The KAJ09TGGR is a 9-position DIP switch manufactured by E-Switch, configured as a single-pole single-throw (SPST) surface mount component rated for 25mA at 24VDC. This part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KAJ09TGGR is determined by strict equivalence across the following critical parameters: circuit configuration (SPST), position count (9), current rating (25mA), voltage rating (24VDC), actuator type (slide standard), mounting method (surface mount), termination style (gull wing), and pitch spacing (0.100"). All identified substitutes maintain these core electrical and mechanical specifications. Packaging format (tube versus tape & reel) represents a logistics variation that does not affect functional compatibility. Minor dimensional variations in height above board and overall length remain within acceptable tolerances for PCB layout and assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both DMR09T and DMR09TTR from APEM Inc. are functionally equivalent substitutes for the obsolete KAJ09TGGR. The primary distinction between these two alternatives is packaging format: DMR09T is supplied in tube packaging, while DMR09TTR is supplied in tape & reel format. Selection between these options depends on assembly process requirements and volume considerations. Both substitutes maintain active product status, ensuring long-term availability and supply chain stability. All three parts satisfy ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can DMR09T and DMR09TTR be used interchangeably with KAJ09TGGR? A: Yes. Both APEM Inc. parts are electrically and mechanically equivalent to the KAJ09TGGR. They share identical circuit configuration, position count, current and voltage ratings, actuator type, mounting method, and termination style. Packaging format does not affect functional compatibility.

Q: What is the difference between DMR09T and DMR09TTR? A: The primary difference is packaging. DMR09T is supplied in tube packaging, while DMR09TTR is supplied in tape & reel format. Both parts are otherwise identical in electrical and mechanical specifications. Tape & reel packaging is typically preferred for high-volume automated assembly processes.

Q: Are there dimensional differences between the KAJ09TGGR and its substitutes? A: Minor dimensional variations exist. The KAJ09TGGR has a height above board of 0.140" (4.65mm) and length of 0.900" (22.86mm), while both APEM substitutes measure 0.146" (3.70mm) in height and 0.937" (23.80mm) in length. These differences remain within acceptable tolerances for standard PCB layouts and do not affect functional compatibility.

Q: Do the substitute parts support the same operating temperature range? A: The KAJ09TGGR operates from -40°C to 85°C, while the APEM substitutes operate from -20°C to 85°C. For applications requiring operation below -20°C, the original KAJ09TGGR specification must be maintained if available from inventory.

Q: Are all three parts RoHS and REACH compliant? A: Yes. The KAJ09TGGR and both APEM substitutes are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
