STU-053A16AX Equivalent & Substitute Parts

Part Overview

The STU-053A16AX is a tactile switch manufactured by Mitsumi Electric Company Ltd, designed for surface mount applications with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration. This component operates at 0.02A @ 15VDC with top actuated orientation and IP68 ingress protection rating. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing production, maintenance, and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STU-053A16AX is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom
• Contact rating: 0.02A @ 15VDC

Mechanical Compatibility:

• Mounting type: Surface Mount
• Actuator orientation: Top Actuated
• Outline dimensions: 2.80mm x 1.90mm
• Termination style: SMD (SMT) Tab
• Actuator height: 0.53mm

Environmental & Regulatory:

• Ingress protection rating: IP67 or higher
• RoHS compliance status
• ECCN classification: EAR99

The EVP-BL2A1B000 from Panasonic Electronic Components meets all critical substitution criteria within the allowed parameter tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

The EVP-BL2A1B000 is the direct substitute for the obsolete STU-053A16AX. Both components share identical electrical specifications, mechanical dimensions, and mounting characteristics. The substitute part is currently in active production status with 9228 units available in inventory, ensuring supply chain continuity.

The EVP-BL2A1B000 maintains ROHS3 compliance and carries the same ECCN classification (EAR99). The ingress protection rating of IP67 on the substitute part exceeds the original IP68 specification, providing equivalent or superior environmental sealing performance. Operating force differential of 3gf (160gf vs. 163gf) falls within normal manufacturing tolerances for tactile switches and does not impact functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EVP-BL2A1B000 be used as a direct replacement for the STU-053A16AX?

A: Yes. Both parts share identical circuit configuration (SPST-NO), contact rating (0.02A @ 15VDC), mounting type (Surface Mount), physical outline (2.80mm x 1.90mm), actuator height (0.53mm), and termination style (SMD Tab). Electrical and mechanical compatibility is confirmed.

Q: What is the difference in ingress protection ratings?

A: The original STU-053A16AX carries IP68 rating (dust tight, waterproof). The substitute EVP-BL2A1B000 carries IP67 rating (dust tight, waterproof). Both ratings provide sealed operation; IP67 is suitable for applications requiring dust and water ingress protection.

Q: Are there packaging differences between these parts?

A: The STU-053A16AX packaging is listed as standard; the EVP-BL2A1B000 is supplied in Tape & Reel (TR) format. Both are surface mount compatible. Tape & Reel packaging is standard for high-volume SMT assembly operations.

Q: What is the operating force difference?

A: The STU-053A16AX specifies 163gf operating force; the EVP-BL2A1B000 specifies 160gf. This 3gf difference is within normal manufacturing tolerances for tactile switches and does not affect functional performance or user experience.

Q: Are both parts RoHS compliant?

A: Yes. The STU-053A16AX is RoHS Compliant; the EVP-BL2A1B000 is ROHS3 Compliant. Both meet current RoHS requirements for restricted substance elimination.
