Equivalent & Substitute Parts for Grayhill 95C04A3T Tactile Switch

Part Overview

The Grayhill 95C04A3T is an active SPST-NO tactile switch designed for through-hole mounting applications requiring low-current switching at 12VDC. This component delivers tactile feedback with a 160gf operating force and supports up to 50,000 mechanical cycles. The switch is packaged in tube format and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute parts are identified to address inventory availability, packaging preferences, or specific mechanical parameter requirements while maintaining functional equivalence in SPST-NO circuit topology and electrical contact ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Grayhill 95C04A3T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be SPST-NO
• Contact rating must support 0.05A @ 12VDC minimum
• Switch function must be Off-Mom (momentary operation)

Mechanical Equivalence Requirements:

• Mounting type must be through-hole
• Actuator orientation must be top-actuated
• Termination style must be PC pin
• Outline dimensions must be 6.00mm x 3.50mm
• Switch travel must be 0.25mm

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture sensitivity level must be 1 (unlimited)
• REACH unaffected status required

The E-Switch TL1107BF180WQ meets all electrical and mechanical equivalence criteria. Variations in operating force (180gf vs. 160gf), actuator height (5.00mm vs. 4.30mm), mechanical life (40,000 vs. 50,000 cycles), and operating temperature range (-20°C to 70°C vs. -25°C to 70°C) do not disqualify substitution when the primary electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Grayhill 95C04A3T): Select the Grayhill 95C04A3T when the original specification requires the lower operating force of 160gf, the extended lower temperature rating of -25°C, or the higher mechanical life rating of 50,000 cycles. This part maintains active product status with full RoHS3 and REACH compliance.

Substitute Selection (E-Switch TL1107BF180WQ): The E-Switch TL1107BF180WQ serves as a functional substitute when inventory availability of the primary part is constrained or when bulk packaging is preferred over tube packaging. This part satisfies all critical electrical and mechanical interface requirements with active product status and equivalent compliance certifications. The higher operating force of 180gf and reduced mechanical life of 40,000 cycles do not impact substitution eligibility for applications within the specified electrical and thermal operating envelope.

Both parts maintain identical circuit topology, contact ratings, mounting interfaces, and outline dimensions. Selection between these parts depends on application-specific requirements for actuator force sensitivity, temperature extremes, or expected cycle life within the stated mechanical life parameters.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch TL1107BF180WQ replace the Grayhill 95C04A3T in all applications?

A: The E-Switch TL1107BF180WQ is electrically and mechanically equivalent for SPST-NO momentary switching at 0.05A @ 12VDC with identical through-hole mounting and PC pin termination. However, applications requiring the lower 160gf operating force or extended -25°C lower temperature rating should retain the Grayhill part. Applications with cycle life requirements exceeding 40,000 cycles should use the Grayhill part.

Q: What is the impact of the 0.7mm difference in actuator height?

A: The Grayhill 95C04A3T has an actuator height of 4.30mm while the E-Switch TL1107BF180WQ measures 5.00mm. This 0.7mm difference may affect panel cutout design, actuator clearance to surrounding components, or user interface ergonomics. PCB layout compatibility is maintained due to identical outline dimensions and PC pin termination.

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

A: The Grayhill 95C04A3T operates from -25°C to 70°C, while the E-Switch TL1107BF180WQ operates from -20°C to 70°C. Applications requiring operation below -20°C must use the Grayhill part. Both parts support the full 70°C upper temperature limit.

Q: What packaging differences exist between these parts?

A: The Grayhill 95C04A3T is supplied in tube packaging, while the E-Switch TL1107BF180WQ is supplied in bulk packaging. Tube packaging provides individual component protection and is suitable for lower-volume assembly operations. Bulk packaging is optimized for high-volume manufacturing environments.

Q: Do both parts meet the same compliance standards?

A: Both the Grayhill 95C04A3T and E-Switch TL1107BF180WQ are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Compliance certifications are equivalent across both parts.

Q: What is the significance of the 20gf difference in operating force?

A: The E-Switch TL1107BF180WQ requires 180gf operating force compared to 160gf for the Grayhill 95C04A3T. This 20gf increase represents approximately 12.5% higher actuation force. Applications with tactile feedback sensitivity requirements or user interface feel specifications should account for this difference during design validation.

Q: How do the mechanical life ratings compare?

A: The Grayhill 95C04A3T is rated for 50,000 mechanical cycles, while the E-Switch TL1107BF180WQ is rated for 40,000 cycles. Applications with cycle life requirements exceeding 40,000 cycles should use the Grayhill part. Both ratings assume operation within specified electrical and temperature parameters.
