TPA511GLFS Navigation Switch - Equivalent & Substitute Parts

Part Overview

The TPA511GLFS is a 2-axis digital navigation switch manufactured by C&K, designed for surface mount applications with gull wing termination. This component provides 4-way directional control with center select functionality, rated for 50mA at 24V DC with a mechanical life of 200,000 cycles. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPA511GLFS is determined by the following core parameters:

• Functional Type: 2-axis navigation switch with 4-way directional and center select capability
• Output Configuration: Digital mechanical switch output
• Mounting & Termination: Surface mount with gull wing termination
• Electrical Ratings: Current and voltage ratings must not exceed the application requirements
• Environmental Specifications: Operating temperature range and mechanical life cycles
• Compliance: RoHS and REACH compliance status

The JS5208 qualifies as a substitute based on matching functional type, output configuration, mounting style, and termination. However, electrical and environmental parameters differ and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The JS5208 from E-Switch is available as an active product with current manufacturing support, providing supply chain continuity for the obsolete TPA511GLFS. Both components share identical functional architecture and mounting characteristics.

Selection of the JS5208 requires verification that application electrical requirements do not exceed 20mA at 15V DC, as these ratings are lower than the original TPA511GLFS specification. The JS5208 operates within a narrower temperature range (-20°C to 70°C versus -40°C to 85°C) and provides half the mechanical life cycles (100,000 versus 200,000). Operating force characteristics differ, with the JS5208 requiring higher actuation force (280/500gf versus 180/400gf).

Both components maintain RoHS and REACH compliance, supporting regulatory requirements for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the JS5208 directly replace the TPA511GLFS in existing designs?

A: Direct replacement is possible only if the application operates within JS5208 electrical limits (20mA maximum, 15V maximum) and environmental specifications (-20°C to 70°C operating range). The higher operating force and reduced mechanical life must be evaluated against system requirements.

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

A: The primary differences are electrical ratings (50mA/24V for TPA511GLFS versus 20mA/15V for JS5208), operating temperature range (40°C wider for TPA511GLFS), mechanical life (2x higher for TPA511GLFS), and operating force (higher for JS5208). Functional type and mounting characteristics are identical.

Q: Why is the TPA511GLFS obsolete?

A: Product obsolescence is determined by the manufacturer. The JS5208 provides an active alternative with equivalent functional capability and current manufacturing availability.

Q: Are there packaging considerations for substitution?

A: Both components use surface mount gull wing termination. The TPA511GLFS was available in bulk packaging, while the JS5208 is specified as bulk. Verify packaging requirements for your procurement process.

Q: Do both parts meet current compliance standards?

A: Yes. The TPA511GLFS is RoHS Compliant and REACH Unaffected. The JS5208 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.
