Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FLEX-14-7-10 is determined by the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration must remain SPST-NO
• Glass body reed switch type
• Through-hole axial termination
• Operating temperature range compatibility (-40°C ~ 125°C)
• RoHS3 compliance and REACH unaffected status

Electrical Performance Compatibility: Substitute parts must maintain or exceed the switching current and voltage ratings. The FLEX-14-7-10 operates at 350mA AC / 500mA DC with 140V AC / 200V DC switching capability. Substitute components must support these electrical parameters or higher ratings to ensure functional equivalence in the target application circuit.

Mechanical Compatibility: Both the main part and substitute must feature through-hole axial termination for direct PCB mounting compatibility without requiring adapter modifications or redesign of the mounting footprint.

The SW GP560/10-15 AT from Standex-Meder Electronics qualifies as a substitute based on matching circuit configuration (SPST-NO), glass body reed type, through-hole axial termination, identical operating temperature range, and equivalent compliance certifications. The substitute part provides higher current switching capability (1A AC/DC) and maintains the 10W/10VA power rating envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the FLEX-14-7-10 and SW GP560/10-15 AT maintain Active product status with full RoHS3 compliance and REACH unaffected certification, ensuring regulatory compliance for current and future applications. Selection between these components should be based on specific circuit voltage and current requirements within the application design envelope.

The FLEX-14-7-10 is suitable for applications requiring 140V AC / 200V DC switching with current loads up to 350mA AC or 500mA DC. The SW GP560/10-15 AT provides higher current switching capacity (1A AC/DC) but operates at reduced voltage ratings (125V AC / 100V DC). Direct substitution is valid only when the target application operates within the voltage and current specifications of the selected component.

Both parts feature identical operating temperature range (-40°C ~ 125°C), capacitance (0.2 pF), and moisture sensitivity level (MSL 1 - Unlimited), ensuring thermal and environmental performance equivalence. Through-hole axial termination is consistent across both components, eliminating PCB redesign requirements for mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SW GP560/10-15 AT directly replace the FLEX-14-7-10 in all applications?

A: Direct substitution is valid only when the application circuit operates within the voltage specifications of the SW GP560/10-15 AT (125V AC / 100V DC maximum). If the circuit requires 140V AC or 200V DC switching, the FLEX-14-7-10 must be retained. Both parts support identical current switching in DC applications (500mA and 1A respectively), and the substitute provides higher current capacity.

Q: What are the key electrical differences between these two reed switches?

A: The FLEX-14-7-10 supports 140V AC / 200V DC switching with 350mA AC / 500mA DC current capacity. The SW GP560/10-15 AT supports 125V AC / 100V DC switching with 1A AC/DC current capacity. Both maintain 10W/10VA power ratings. Selection depends on whether the application requires the higher voltage capability of the FLEX-14-7-10 or the higher current capacity of the SW GP560/10-15 AT.

Q: Are there any packaging or mounting differences?

A: Both components feature through-hole axial termination and are suitable for identical PCB mounting configurations. The FLEX-14-7-10 is supplied in Box packaging, while the SW GP560/10-15 AT is supplied in Bulk packaging. No mechanical redesign is required for substitution.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the FLEX-14-7-10 and SW GP560/10-15 AT are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the operate range specification, and how does it affect substitution?

A: The FLEX-14-7-10 has an operate range of 7 ~ 10AT (ampere-turns), while the SW GP560/10-15 AT has an operate range of 10 ~ 50AT. The operate range defines the magnetic field strength required to activate the reed switch. Application-specific magnetic field characteristics must be verified to ensure the selected component activates within the intended operating environment.
