Substitute Part Grouping Explanation

Substitution eligibility for the SS-20007 magnetic switch is determined by the following parameters:

Primary Substitution Criteria:

• Manufacturer: Honeywell Sensing and Productivity Solutions (same manufacturer ensures design compatibility)
• Category: Magnetic Sensors (functional equivalence)
• Function: Digital switching via magnetic field detection
• Technology: Hall Effect sensing (detection method)
• Polarization: South Pole magnet actuation (magnetic orientation)
• RoHS Compliance: RoHS Compliant status (regulatory alignment)

Secondary Compatibility Parameters:

• Supply Voltage Range: Overlap within 4.5V to 24V envelope
• Operating Temperature Range: Coverage of -40°C to 85°C minimum
• Output Type: Current or Open Collector configurations
• Termination Style: Wire Leads or Through Hole mounting

The two identified substitutes—SR3F-A1 and SS449R—meet these core criteria while offering different output configurations and package options to accommodate varying circuit design requirements.

Engineering Selection Recommendations

SR3F-A1 Selection Criteria:

• Choose SR3F-A1 when current output configuration is required
• Suitable for applications requiring wire lead termination and flange mount packaging
• Operating temperature range of -40°C to 85°C covers standard industrial applications
• Supply voltage range 4.5V to 24V accommodates most control circuit designs
• Active product status ensures continued availability and support
• RoHS Compliant designation meets environmental and regulatory requirements

SS449R Selection Criteria:

• Choose SS449R when open collector output is required for direct logic circuit integration
• Suitable for applications requiring through-hole mounting on printed circuit boards
• Extended operating temperature range of -40°C to 150°C supports high-temperature environments
• Lower minimum supply voltage (3V) enables battery-powered applications
• Higher maximum output current (20mA) supports direct LED or relay driver applications
• Unipolar switch function with defined trip (46mT) and release (13.5mT) thresholds provides predictable switching behavior
• Active product status and high inventory (3521 units) ensure supply continuity

Both substitutes maintain RoHS compliance and are manufactured by Honeywell Sensing and Productivity Solutions, ensuring design consistency and quality standards equivalent to the original SS-20007 component.

Frequently Asked Questions (FAQ)

Q: What determines whether SR3F-A1 or SS449R can substitute for SS-20007?

A: Substitution is determined by matching the core functional parameters: Hall Effect technology, South Pole polarization, Honeywell manufacturer origin, and RoHS compliance. The specific choice between SR3F-A1 and SS449R depends on output type requirements (current versus open collector) and package form factor compatibility with your circuit design.

Q: What is the primary difference between SR3F-A1 and SS449R?

A: SR3F-A1 provides current output with wire lead termination and barrel plastic housing suitable for panel or flange mounting. SS449R provides open collector output with through-hole TO-92-3 package suitable for printed circuit board assembly. Additionally, SS449R supports extended temperature operation to 150°C and lower minimum supply voltage (3V).

Q: Can I use SS449R in applications requiring wire leads instead of through-hole mounting?

A: No. SS449R is designed for through-hole mounting on printed circuit boards. For wire lead applications, SR3F-A1 is the appropriate substitute with its wire lead termination and flange mount configuration.

Q: Are both substitutes RoHS compliant?

A: Yes. Both SR3F-A1 and SS449R carry RoHS Compliant status, meeting environmental and regulatory requirements equivalent to the original SS-20007 component.

Q: What supply voltage range is common to all three parts?

A: The overlapping supply voltage range across all three components is 4.5V to 24V. SS449R extends the lower limit to 3V, enabling additional low-voltage applications.

Q: Which substitute has higher current output capability?

A: SS449R provides maximum output current of 20mA with open collector configuration. SR3F-A1 provides current output but maximum current specification is not provided in the available data.

Q: What is the inventory status for each part?

A: SS-20007 has 716 units in stock, SR3F-A1 has 864 units in stock, and SS449R has 3521 units in stock. All are listed as new original components.
