GDS001 Equivalent & Substitute Parts

Part Overview

The GDS001 is a surface mount SPST-NO (Single Pole Single Throw - Normally Open) switch detector manufactured by C&K, designed for 1mA DC operation at 5V. This component features an angled toggle detector actuator with SMD tab termination and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for design continuity and procurement planning. The GDS001 maintains RoHS compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for standard commercial applications requiring low-current switching functionality.

Substitute Part Grouping Explanation

The ESE-22MH24 manufactured by Panasonic Electronic Components qualifies as a functional substitute for the GDS001 based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Voltage rating: 5V DC
• Actuator type: Angled Toggle (Detector)
• Mounting type: Surface Mount
• Termination style: SMD (SMT) Tab
• Operating force: 30gf
• Electrical life: 50,000 Cycles
• Mechanical life: 50,000 Cycles
• RoHS compliance: Yes (ROHS3 Compliant)
• MSL rating: 1 (Unlimited)

Allowable Variance:

• Current rating: ESE-22MH24 rated at 10mA DC, which exceeds the GDS001's 1mA requirement and remains within acceptable operating margins for low-current switching applications
• Operating position: ESE-22MH24 at 0.091" (2.3mm) versus GDS001 at 0.087" (2.2mm) represents a 0.004" (0.1mm) difference, within mechanical tolerance for detector switch applications
• Operating temperature range: ESE-22MH24 operates -10°C to 70°C versus GDS001 at -20°C to 70°C; the substitute has a narrower lower temperature bound but covers standard commercial operating conditions

Parameter Comparison

Engineering Selection Recommendations

The ESE-22MH24 is suitable as a direct substitute for the obsolete GDS001 in applications where the following conditions are met:

Product Status Consideration: The GDS001 is classified as obsolete, making the active-status ESE-22MH24 the appropriate long-term solution for new designs and ongoing production requirements.

Compliance Alignment: Both parts maintain RoHS compliance and unlimited MSL ratings. The ESE-22MH24 carries ROHS3 certification, representing current regulatory compliance standards.

Current Rating: The ESE-22MH24's 10mA DC rating accommodates the GDS001's 1mA requirement with adequate margin. This higher rating does not compromise functionality in low-current switching circuits.

Mechanical Compatibility: The 0.1mm variance in operating position and right-angle mounting configuration of the ESE-22MH24 are compatible with standard PCB layouts designed for detector switch applications.

Temperature Operating Range: For applications operating within -10°C to 70°C, the ESE-22MH24 provides full compatibility. Applications requiring operation below -10°C require alternative component evaluation.

Frequently Asked Questions (FAQ)

Q: Can the ESE-22MH24 directly replace the GDS001 in existing designs?

A: Yes, the ESE-22MH24 is functionally compatible for applications operating within -10°C to 70°C. The higher current rating (10mA vs. 1mA) and minimal mechanical variance (0.1mm operating position difference) do not impact performance in standard detector switch circuits. PCB layout verification is recommended to confirm right-angle mounting compatibility.

Q: What is the significance of the current rating difference between these parts?

A: The GDS001 is rated for 1mA DC, while the ESE-22MH24 is rated for 10mA DC. The substitute's higher rating indicates it can safely handle greater current loads. In applications using only 1mA, the ESE-22MH24 operates well within its safe operating range with no adverse effects.

Q: Are there packaging differences between these parts?

A: The GDS001 packaging is listed as standard SMD tab termination. The ESE-22MH24 is available in Cut Tape (CT) and Digi-Reel packaging formats. Both use identical SMD (SMT) tab termination style, ensuring compatibility with standard surface mount assembly processes.

Q: Does the operating temperature range difference affect substitution?

A: The GDS001 operates from -20°C to 70°C, while the ESE-22MH24 operates from -10°C to 70°C. For applications within the -10°C to 70°C range, the ESE-22MH24 is fully compatible. Applications requiring operation below -10°C must retain the GDS001 or identify alternative components with extended low-temperature ratings.

Q: What compliance certifications apply to the ESE-22MH24?

A: The ESE-22MH24 is ROHS3 compliant and REACH unaffected, matching the regulatory compliance profile of the GDS001. Both parts carry unlimited MSL ratings (MSL 1), indicating no moisture sensitivity restrictions for storage and handling.
