COM-09190 Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The COM-09190 is a tactile switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, manufactured by SparkFun Electronics. This component features top actuation, through-hole mounting, and PC pin termination in a 12.00mm x 12.00mm outline. The product is active and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent functional performance can be achieved through components sharing the same circuit topology, mounting methodology, and physical form factor. Identification of alternatives becomes necessary when primary inventory is unavailable or when design requirements permit selection from multiple qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the COM-09190 is determined by strict alignment with the following parameters:

Primary Substitution Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Actuator orientation: Top Actuated
• Mounting type: Through Hole
• Termination style: PC Pin
• Physical outline: 12.00mm x 12.00mm
• Illumination status: Non-Illuminated
• Product status: Active
• Regulatory compliance: ROHS3 Compliant

The substitute part TL1100EF160Q from E-Switch satisfies all primary substitution criteria. Both components share identical circuit topology, mounting methodology, physical dimensions, and regulatory compliance status. The substitute part provides additional specified parameters including contact rating, operating force, actuator height, switch travel, mechanical life, and operating temperature range, which are not specified for the main part but do not conflict with application requirements.

Parameter Comparison

Engineering Selection Recommendations

COM-09190 (SparkFun Electronics):

• Primary selection when SparkFun component availability and supply chain continuity are required
• Active product status with established inventory support
• ROHS3 compliant and MSL 1 rated for standard PCB assembly processes

TL1100EF160Q (E-Switch):

• Qualified substitute when COM-09190 inventory is unavailable
• Active product status with higher inventory availability (27,692 units in stock versus 971 units)
• ROHS3 compliant and MSL 1 rated with identical regulatory standing
• Provides fully specified electrical and mechanical parameters: 0.05A @ 12VDC contact rating, 160gf operating force, 7.50mm actuator height, 0.30mm switch travel, 100,000 cycle mechanical life, and -20°C to 70°C operating temperature range
• REACH unaffected status provides additional regulatory documentation

Both components are suitable for direct substitution in applications requiring SPST-NO momentary tactile switches with through-hole mounting and top actuation in standard 12.00mm x 12.00mm packages.

Frequently Asked Questions (FAQ)

Q: Can TL1100EF160Q be used as a direct replacement for COM-09190?

A: Yes. Both components share identical circuit configuration (SPST-NO), switch function (Off-Mom), mounting type (Through Hole), actuator orientation (Top Actuated), termination style (PC Pin), physical outline (12.00mm x 12.00mm), and regulatory compliance (ROHS3, MSL 1). The components are functionally equivalent for PCB-level substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: SPST-NO circuit configuration, momentary (Off-Mom) switch function, standard actuator type, through-hole mounting, top actuation orientation, PC pin termination, 12.00mm x 12.00mm outline dimensions, non-illuminated status, active product status, and ROHS3 compliance. All parameters must align for substitution to be valid.

Q: Does the TL1100EF160Q provide additional specifications not listed for COM-09190?

A: Yes. The TL1100EF160Q includes fully specified contact rating (0.05A @ 12VDC), operating force (160gf), actuator height (7.50mm), switch travel (0.30mm), mechanical life (100,000 cycles), and operating temperature range (-20°C to 70°C). These specifications do not conflict with COM-09190 application requirements and provide additional design reference data.

Q: Are there any packaging or inventory considerations?

A: Both components are supplied in bulk packaging. TL1100EF160Q has significantly higher inventory availability (27,692 units) compared to COM-09190 (971 units), which may influence supply chain planning and lead time considerations.

Q: What is the regulatory compliance status of both components?

A: Both COM-09190 and TL1100EF160Q are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level. TL1100EF160Q additionally carries REACH Unaffected status. Both components are classified under ECCN EAR99 and HTSUS 8536.50.9031.
