LS70C2D-T Equivalent & Substitute Parts

Part Overview

The LS70C2D-T is a tactile switch manufactured by Citizen, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a rated contact capacity of 0.02A at 12VDC. This surface-mounted component features top actuation and is designed for low-power switching applications. The LS70C2D-T is currently listed as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design and procurement requirements. Substitute parts must maintain electrical compatibility and mechanical form factors suitable for surface-mount assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LS70C2D-T are selected based on strict electrical and mechanical compatibility criteria. The following parameters define substitution eligibility:

Mandatory Matching Parameters:

• Circuit Type: SPST-NO
• Switch Function: Off-Mom (Momentary)
• Mounting Type: Surface Mount
• Actuator Orientation: Top Actuated
• Contact Rating compatibility: minimum 0.02A at rated voltage

Allowable Parameter Variations:

• Voltage rating may exceed 12VDC (higher ratings accommodate 12VDC operation)
• Operating force may vary within tactile switch tolerances (160-163gf range acceptable)
• Actuator height and outline dimensions may differ if PCB assembly space permits
• Termination style may differ (SMD Tab vs. Gull Wing) based on PCB layout
• Mechanical life ratings may exceed minimum requirements
• Product status change from Obsolete to Active is acceptable for substitution purposes

The LS70C2DS-T and EVP-BB2A9B000 meet these substitution criteria and represent valid alternatives for the discontinued LS70C2D-T.

Parameter Comparison

Engineering Selection Recommendations

LS70C2DS-T: This Citizen part represents the closest functional and dimensional equivalent to the discontinued LS70C2D-T. Both components share identical electrical ratings, outline dimensions, actuator height, and switch travel specifications. The LS70C2DS-T carries Active product status, ensuring continued availability. This part includes IP67 ingress protection and is ROHS3 compliant, meeting current regulatory requirements. The primary difference is packaging format (Tape & Reel vs. undefined for the original), which does not affect electrical or mechanical performance.

EVP-BB2A9B000: The Panasonic EVP-BB2A9B000 provides an alternative from a different manufacturer. This part exceeds the voltage rating of the original (15VDC vs. 12VDC) and offers enhanced mechanical life (500,000 cycles vs. 100,000 cycles). Dimensional differences are present: smaller outline (2.60mm x 1.60mm vs. 2.80mm x 2.30mm) and reduced actuator height (0.53mm vs. 0.60mm). The EVP-BB2A9B000 includes defined operating temperature range (-40°C ~ 85°C) and IP67 protection. Selection of this part requires PCB layout verification due to dimensional variance and termination style change from SMD Tab to Gull Wing.

Frequently Asked Questions (FAQ)

Q: Can the LS70C2DS-T be used as a direct replacement for the LS70C2D-T?

A: Yes. The LS70C2DS-T is functionally and mechanically equivalent. Both components maintain SPST-NO circuit topology, identical contact ratings (0.02A @ 12VDC), matching outline dimensions (2.80mm x 2.30mm), and equivalent actuator specifications. The transition from Obsolete to Active product status is advantageous for procurement. Packaging format differences do not affect component performance.

Q: What are the key differences between the Citizen LS70C2DS-T and Panasonic EVP-BB2A9B000?

A: The primary differences are outline dimensions (LS70C2DS-T: 2.80mm x 2.30mm; EVP-BB2A9B000: 2.60mm x 1.60mm), actuator height (0.60mm vs. 0.53mm), termination style (SMD Tab vs. Gull Wing), and mechanical life rating (100,000 vs. 500,000 cycles). The Panasonic part offers higher voltage rating (15VDC vs. 12VDC) and specified operating temperature range. PCB layout compatibility must be confirmed before substitution.

Q: Are there packaging considerations when substituting these parts?

A: The LS70C2D-T original packaging format is not specified in available documentation. The LS70C2DS-T is supplied in Tape & Reel format, standard for surface-mount assembly operations. The EVP-BB2A9B000 is also supplied in Tape & Reel format. Both substitute parts are compatible with automated pick-and-place assembly processes.

Q: Do all substitute parts meet current compliance standards?

A: The LS70C2DS-T and EVP-BB2A9B000 are both ROHS3 compliant and carry MSL 1 (Unlimited moisture sensitivity level) ratings. The EVP-BB2A9B000 includes REACH Unaffected designation. Both parts meet current environmental and regulatory requirements for electronic component use.

Q: What is the impact of different switch travel specifications?

A: The LS70C2D-T and LS70C2DS-T both specify 0.15mm switch travel. The EVP-BB2A9B000 specifies 0.11mm travel. This difference affects tactile feedback and mechanical response characteristics. Applications with specific travel requirements should maintain the 0.15mm specification (both Citizen parts). The 0.11mm travel of the Panasonic part is suitable for designs not dependent on travel distance.

Q: Can the EVP-BB2A9B000 be used in applications designed for 12VDC operation?

A: Yes. The EVP-BB2A9B000 is rated for 0.02A @ 15VDC, which exceeds the 12VDC requirement of the original LS70C2D-T. Higher voltage-rated components safely accommodate lower voltage operation. However, PCB layout changes are required due to the smaller outline dimensions and Gull Wing termination style.
