GDS04STR Equivalent & Substitute Parts

Part Overview

The GDS04STR is a 4-position surface mount DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This component is a single-pole single-throw (SPST) slide switch rated for 25mA at 24VDC, designed for applications requiring compact, washable switching functionality. The GDS04STR is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where original inventory becomes unavailable.

Engineering Selection Recommendations

The part 1825006-8 is the direct functional equivalent and substitute for the GDS04STR. Selection of 1825006-8 is supported by the following engineering factors:

Functional Equivalence: All critical electrical and mechanical parameters are identical between the GDS04STR and 1825006-8, including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and pitch specifications.

Product Status: The GDS04STR is classified as obsolete, while 1825006-8 is active product status. This distinction ensures continued availability and manufacturing support for 1825006-8.

Regulatory Compliance: The 1825006-8 is ROHS3 compliant, whereas the GDS04STR is RoHS non-compliant. For applications subject to RoHS requirements, 1825006-8 provides improved regulatory alignment.

Contact Finish Compatibility: The GDS04STR features gold contact finish, while 1825006-8 features gold alloy contact finish. Both finishes are compatible with the same electrical and environmental performance requirements.

Packaging Availability: The 1825006-8 is available in Cut Tape (CT) packaging with significantly higher inventory levels (9,620 pieces) compared to the GDS04STR (796 pieces), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 1825006-8 be used as a direct replacement for GDS04STR in existing designs?

A: Yes. The 1825006-8 meets all critical electrical and mechanical parameters required for direct functional replacement. Identical circuit configuration (SPST), position count (4), current rating (25mA), voltage rating (24VDC), actuator type, mounting type, termination style, and pitch ensure pin-for-pin and functional compatibility.

Q: What is the difference between the gold contact finish on GDS04STR and the gold alloy finish on 1825006-8?

A: Both contact finishes are compatible with the specified electrical performance (25mA at 24VDC) and operating temperature range (-30°C to 85°C). Gold alloy finishes are commonly used in modern manufacturing and provide equivalent performance for this application class.

Q: Why is the GDS04STR classified as obsolete?

A: The GDS04STR is no longer in active production. The 1825006-8 represents the current active equivalent from TE Connectivity ALCOSWITCH Switches and is the recommended part for new designs and ongoing supply requirements.

Q: Are there any differences in mechanical life or electrical life between these parts?

A: No. Both the GDS04STR and 1825006-8 are rated for 1,000 mechanical cycles and 1,000 electrical cycles, ensuring equivalent operational durability.

Q: What packaging options are available for the substitute part 1825006-8?

A: The 1825006-8 is available in Cut Tape (CT) packaging format, which is standard for surface mount DIP switches and compatible with automated assembly processes.

Q: Does the 1825006-8 meet RoHS requirements?

A: Yes. The 1825006-8 is ROHS3 compliant. The original GDS04STR is RoHS non-compliant. For applications requiring RoHS compliance, the 1825006-8 is the appropriate selection.

Q: Are the physical dimensions identical between GDS04STR and 1825006-8?

A: Yes. Both parts share identical dimensions: 0.394" (10.01mm) length, 0.114" (2.90mm) height above board, and 0.100" (2.54mm) pitch. PCB layout and footprint compatibility are maintained.

Q: Can 1825006-8 be used in washable applications?

A: Yes. The 1825006-8 is rated as washable with tape seal features, identical to the GDS04STR, supporting applications requiring cleaning or moisture exposure.
