MJTP1212 Tactile Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The MJTP1212 is an active-status tactile switch manufactured by APEM Inc., configured as a SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch. This through-hole mounted component is rated for 0.05A at 12VDC with a 12.00mm x 12.00mm footprint and 4.30mm actuator height. The switch provides tactile feedback with 160gf operating force and 100,000 mechanical life cycles. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical dimensions, mounting compatibility, and functional characteristics within the tactile switch product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MJTP1212 are qualified based on the following criteria:

Primary Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Contact rating: 0.05A minimum
• Mounting type: Through Hole
• Actuator orientation: Top Actuated
• Outline dimensions: 12.00mm x 12.00mm
• Termination style: PC Pin

Secondary Compatibility Parameters:

• Actuator height off PCB: 4.30mm (primary specification)
• Operating force: 160gf (nominal tolerance acceptable)
• Switch travel: 0.30mm
• Mechanical life: 100,000 cycles minimum
• RoHS3 compliance required

Substitutes are grouped by voltage rating compatibility and actuator type variation. FSM100 operates at 24VDC and is suitable for applications where higher voltage tolerance is acceptable. PTS125SM43-2 LFS, TL1100DF160Q, and TL1100F160Q operate at 12VDC matching the primary specification. TL1100F160Q features a taller 7.30mm actuator height and plunger-type actuator, suitable only for applications with different mechanical clearance requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (12VDC Rating, 4.30mm Actuator Height):

PTS125SM43-2 LFS and TL1100DF160Q are direct functional equivalents to MJTP1212 for applications requiring identical voltage and actuator height specifications. Both parts maintain SPST-NO circuit configuration, 0.05A contact rating at 12VDC, and through-hole mounting with 12.00mm x 12.00mm footprint. PTS125SM43-2 LFS offers extended mechanical life of 200,000 cycles and wider temperature range (-40°C ~ 60°C). TL1100DF160Q matches the MJTP1212 operating temperature range (-20°C ~ 70°C) and mechanical life specification. All three parts are ROHS3 compliant and active-status products.

Voltage-Rated Substitute (24VDC Rating, 4.30mm Actuator Height):

FSM100 is suitable for applications where 24VDC operation is acceptable. This part maintains identical mechanical dimensions, actuator height, and contact current rating (0.05A). FSM100 provides extended operating temperature range (-35°C ~ 85°C) and is ROHS3 compliant. Voltage substitution is valid only when circuit design permits 24VDC operation without functional impact.

Mechanical Variant (12VDC Rating, 7.30mm Actuator Height):

TL1100F160Q features a 7.30mm actuator height with plunger-type actuator, creating 3.00mm additional clearance above PCB. This variant is suitable only for applications with different mechanical envelope requirements or where taller actuator profile is specified. Electrical and functional characteristics remain equivalent to MJTP1212.

Frequently Asked Questions (FAQ)

Q: Can FSM100 be used as a direct replacement for MJTP1212?

A: FSM100 is mechanically and functionally compatible but operates at 24VDC versus MJTP1212's 12VDC rating. Substitution is valid only if the application circuit supports 24VDC operation. Verify voltage compatibility before implementation.

Q: What is the difference between TL1100DF160Q and TL1100F160Q?

A: Both are E-Switch TL1100 series parts with identical electrical specifications. TL1100DF160Q has a standard 4.30mm actuator height matching MJTP1212. TL1100F160Q has a 7.30mm plunger-type actuator, requiring 3.00mm additional PCB clearance. Select based on mechanical envelope requirements.

Q: Does PTS125SM43-2 LFS have different operating force than MJTP1212?

A: PTS125SM43-2 LFS specifies 180gf operating force versus MJTP1212's 160gf. This 20gf difference is within normal tactile switch tolerance and does not affect functional compatibility for standard momentary switch applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. MJTP1212, FSM100, PTS125SM43-2 LFS, TL1100DF160Q, and TL1100F160Q are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the mechanical life difference between MJTP1212 and PTS125SM43-2 LFS?

A: MJTP1212 is rated for 100,000 cycles. PTS125SM43-2 LFS is rated for 200,000 cycles, providing double the mechanical life specification. Both are suitable for standard applications; PTS125SM43-2 LFS offers extended durability for high-cycle-count environments.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes, for parts with matching 4.30mm actuator height (MJTP1212, FSM100, PTS125SM43-2 LFS, TL1100DF160Q). TL1100F160Q requires mechanical redesign due to 7.30mm actuator height. Verify voltage compatibility and operating force tolerance for your specific application before implementation.
