Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3320AF130Q is determined by the following critical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Switch Function: Off-Mom (momentary) operation required
• Mounting Type: Surface mount, right-angle configuration
• Actuator Orientation: Side actuation capability
• Termination Style: Gull wing leads for PCB compatibility
• Contact Rating Compatibility: Substitute must support the electrical load requirements of the original application
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status

The KT11P3SA3M35LFG from C&K meets these core substitution criteria while offering enhanced electrical ratings and environmental protection.

Parameter Comparison

Engineering Selection Recommendations

The KT11P3SA3M35LFG is a qualified substitute for the obsolete TL3320AF130Q based on the following factors:

• Both components maintain identical circuit topology (SPST-NO) and switch function (Off-Mom)
• Both employ surface mount right-angle mounting with side actuation and gull wing termination
• The substitute part carries active product status, ensuring long-term availability and supply chain continuity
• Both components achieve ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• The KT11P3SA3M35LFG provides enhanced electrical ratings (1VA @ 32VAC/DC versus 0.05A @ 12VDC), supporting broader application flexibility
• The substitute offers extended operating temperature range (-40°C ~ 90°C) and increased mechanical life (100,000 cycles)
• IP57 ingress protection on the substitute provides additional environmental robustness

Frequently Asked Questions (FAQ)

Q: Can the KT11P3SA3M35LFG directly replace the TL3320AF130Q on existing PCBs?

A: The substitute part maintains identical mounting type (surface mount, right angle), actuator orientation (side actuated), and termination style (gull wing). However, outline dimensions differ slightly (7.77mm x 4.61mm versus 7.10mm x 6.35mm). PCB layout verification is required to confirm footprint compatibility before implementation.

Q: What are the electrical differences between these parts?

A: The TL3320AF130Q is rated at 0.05A @ 12VDC, while the KT11P3SA3M35LFG is rated at 1VA @ 32VAC/DC. The substitute provides significantly higher electrical capacity, making it suitable for applications requiring the original specifications and those with higher electrical demands.

Q: Does the higher operating force of the substitute affect usability?

A: The KT11P3SA3M35LFG requires 300gf operating force compared to 130gf for the original part. This represents a 2.3x increase in actuation force. Application-specific ergonomic and mechanical design considerations must be evaluated to determine acceptability.

Q: Are both parts available in the same packaging format?

A: The TL3320AF130Q is available in standard packaging, while the KT11P3SA3M35LFG is supplied in Tape & Reel (TR) format. Packaging format may affect procurement processes and handling requirements.

Q: What is the compliance status of both parts?

A: Both the TL3320AF130Q and KT11P3SA3M35LFG are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
