Equivalent & Substitute Parts: SW GR560/20-25 AT

Part Overview

The SW GR560/20-25 AT is a glass body reed switch manufactured by Standex-Meder Electronics, configured as a single-pole single-throw normally open (SPST-NO) device. This component operates at 1A switching capacity with 125V AC and 100V DC ratings, delivering 10VA of rated power. The device features an operate range of 20–25AT with axial through-hole termination and is housed in a compact 0.091" diameter glass body measuring 54.00mm in overall length.

The SW GR560/20-25 AT is classified as obsolete. Locating equivalent substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this model is no longer available from primary inventory channels.

Parameter Comparison

Engineering Selection Recommendations

The SW GP560/20-25 AT is the appropriate substitute for the obsolete SW GR560/20-25 AT based on the following factors:

Product Status: The SW GR560/20-25 AT is classified as obsolete, while the SW GP560/20-25 AT maintains active manufacturing status. This ensures continued availability and supply chain reliability for new procurements and field replacements.

Electrical Compatibility: All critical electrical parameters—switching current, voltage ratings (AC and DC), rated power, operate time, and release time—are identical between the two devices. The substitute's broader operate range (10–50AT) encompasses the original specification (20–25AT), ensuring functional compatibility within the original design envelope.

Mechanical Compatibility: Physical dimensions, mounting type (through-hole), termination style (axial), and body configuration are identical. Direct board-level substitution is supported without circuit modification or mechanical redesign.

Regulatory Compliance: The substitute meets ROHS3 compliance requirements, whereas the main part does not specify RoHS status. Both components maintain REACH Unaffected status and identical ECCN and HTSUS classifications, supporting regulatory and export requirements.

Inventory Availability: The SW GP560/20-25 AT is available in significantly higher quantities (18,387 pcs) compared to the obsolete main part, supporting both immediate and long-term procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the SW GP560/20-25 AT be used as a direct replacement for the SW GR560/20-25 AT without circuit modification?

A: Yes. All electrical and mechanical parameters are identical or compatible. The substitute operates within the original design specifications and requires no circuit changes or board-level modifications.

Q: What is the significance of the broader operate range (10–50AT) in the substitute part?

A: The substitute's operate range encompasses the original part's 20–25AT specification. This means the substitute will activate within the original design window and is fully compatible with applications designed for the GR560/20-25 AT.

Q: Are there any differences in switching performance between the two parts?

A: No. Operate time (0.6 ms), release time (0.1 ms), switching current (1A AC/DC), and voltage ratings (125V AC / 100V DC) are identical.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The SW GP560/20-25 AT is ROHS3 compliant and maintains REACH Unaffected status, meeting current regulatory standards. The original part does not specify RoHS compliance.

Q: Are the physical dimensions identical?

A: Yes. Both parts feature identical overall length (2.126" / 54.00mm), body diameter (0.091" / 2.30mm), and body length (0.559" / 14.20mm). Through-hole mounting and axial termination are identical, supporting direct board-level substitution.

Q: What is the packaging difference between the two parts?

A: The main part (SW GR560/20-25 AT) packaging is not specified. The substitute (SW GP560/20-25 AT) is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Why is the substitute part actively manufactured while the original is obsolete?

A: The SW GP560/20-25 AT (GP560 series) represents the current production line for this device category from Standex-Meder Electronics. The GR560 series has been discontinued in favor of the GP560 series, which maintains identical electrical and mechanical specifications.

Q: Are there any temperature or environmental differences?

A: No. Both parts operate across the identical temperature range (-40°C to 125°C) and maintain identical moisture sensitivity level (MSL 1 / Unlimited).
