LL1105RF065Q Equivalent & Substitute Parts

Part Overview

The LL1105RF065Q is an active-status tactile switch manufactured by E-Switch, designed for SPST-NO (Single Pole Single Throw - Normally Open) applications. This side-actuated, through-hole component operates at 0.05A @ 12VDC with an operating force of 65gf and mechanical life rating of 5,000,000 cycles. The component is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity classification.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer offerings, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LL1105RF065Q is determined by the following critical parameters:

• Circuit Configuration: Must be SPST-NO
• Mounting Type: Must be Through Hole, Right Angle
• Actuator Orientation: Must be Side Actuated
• Termination Style: Must be PC Pin
• Switch Travel: Must be 0.25mm
• Regulatory Compliance: Must maintain ROHS3 and REACH compliance status

The substitute part 1825968-2 (TE Connectivity ALCOSWITCH Switches, FSMRACD series) satisfies these core substitution criteria. Variations in contact rating voltage (24VDC vs. 12VDC), operating force (160gf vs. 65gf), mechanical life (100,000 vs. 5,000,000 cycles), and operating temperature range (-35°C ~ 85°C vs. -20°C ~ 70°C) represent parameter differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the LL1105RF065Q and 1825968-2 maintain active product status and full regulatory compliance (ROHS3, REACH Unaffected). Selection between these components should be based on application-specific requirements regarding contact voltage rating, operating force tolerance, mechanical cycle life expectations, and operating temperature envelope.

The LL1105RF065Q is specified for 12VDC operation with 5,000,000 cycle mechanical life and operates within -20°C to 70°C. The 1825968-2 is specified for 24VDC operation with 100,000 cycle mechanical life and operates within -35°C to 85°C. Both components share identical circuit configuration, switch function, mounting type, actuator orientation, termination style, and switch travel specifications.

Frequently Asked Questions (FAQ)

Q: Can 1825968-2 be used in place of LL1105RF065Q in a 12VDC circuit?

A: The 1825968-2 is rated for 0.05A @ 24VDC operation. While the contact current rating is identical, the voltage rating difference must be evaluated against circuit design requirements. The component is electrically capable of 12VDC operation, but voltage derating considerations and application-specific safety margins should be confirmed.

Q: What are the mechanical differences between these switches?

A: The LL1105RF065Q operates at 65gf with 5,000,000 cycle mechanical life. The 1825968-2 operates at 160gf with 100,000 cycle mechanical life. The actuator length differs by 0.20mm (6.15mm vs. 6.35mm). These differences affect tactile feedback, actuation effort, and long-term reliability expectations.

Q: Are both components suitable for the same temperature range?

A: No. The LL1105RF065Q operates from -20°C to 70°C. The 1825968-2 operates from -35°C to 85°C. Applications requiring operation below -20°C or above 70°C must use the 1825968-2. Applications limited to -20°C to 70°C can use either component.

Q: Do packaging differences affect PCB assembly compatibility?

A: The LL1105RF065Q is packaged in standard form. The 1825968-2 is packaged in Bulk. Both components use identical Through Hole, Right Angle mounting with PC Pin termination. Packaging format does not affect PCB assembly compatibility.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the LL1105RF065Q and 1825968-2 are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.
