Part Overview

The MJTP1140 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 surface-mount component is rated for 0.05A at 12VDC with top actuation and gull wing termination. The part is RoHS3 compliant and carries MSL 1 (unlimited moisture sensitivity level) classification.

• Outline dimensions (4.20mm x 4.20mm to 6.20mm x 6.20mm)
• Operating temperature range (extended ranges acceptable)
• Packaging format (Bulk, Tube, Cut Tape, Tape & Reel)

The substitute parts listed below maintain core electrical functionality while offering variations in physical form factor and actuator characteristics suitable for different PCB layout and user interface requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain SPST-NO momentary contact functionality with gull wing surface-mount termination and MSL 1 classification. Selection among substitutes depends on specific application constraints:

Bourns 7914G Series (7914G-1-000, 7914G-1-000E, 7914G-1-024E, 7914G-1-032E): These parts offer higher contact ratings (0.1A @ 16VAC/DC) and extended operating temperature range (-55°C ~ 125°C). The 7914G-1-024E variant features a flush actuator (2.62mm height) suitable for low-profile applications. All variants include IP67 ingress protection. Packaging options include Tube, Cut Tape & Digi-Reel, and Tape & Reel formats. Actuator heights range from 2.62mm to 4.19mm with 300gf operating force.

TE Connectivity FSM2 Series (FSM2JELGLTR, FSM2JELGXLTR): These Extended Life parts match the MJTP1140 contact rating (0.05A @ 12VDC) and offer significantly extended mechanical life (1,000,000 cycles versus 100,000 cycles). Both variants feature 2.50mm actuator height and 0.25mm switch travel. Operating force differs: FSM2JELGLTR at 100gf and FSM2JELGXLTR at 50gf. Operating temperature range is -35°C ~ 85°C. Outline dimensions are 6.20mm x 6.20mm. Both are supplied in Tape & Reel packaging.

E-Switch TL3313AF160QG: This part matches the MJTP1140 in contact rating (0.05A @ 12VDC), actuator height (1.50mm), switch travel (0.25mm), mechanical life (100,000 cycles), and operating temperature range (-20°C ~ 70°C). Operating force is 160gf. Outline dimensions are 4.80mm x 4.80mm. Supplied in Tape & Reel packaging. This variant provides the closest dimensional and electrical match to the MJTP1140.

All substitute parts are active-status products with RoHS compliance and MSL 1 ratings, suitable for direct substitution within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 7914G series parts directly replace the MJTP1140 in all applications?

A: The Bourns 7914G series maintains SPST-NO momentary contact functionality and gull wing termination. However, note the following differences: higher contact rating (0.1A @ 16VAC/DC versus 0.05A @ 12VDC), larger outline dimensions (5.00mm x 5.00mm versus 4.20mm x 4.20mm), greater actuator heights (2.62mm to 4.19mm versus 1.50mm), and higher operating force (300gf versus 260gf). These parts are suitable for applications where PCB space permits larger footprints and where higher contact ratings provide design margin.

Q: What is the primary advantage of the TE Connectivity FSM2 series over the MJTP1140?

A: The FSM2 series offers extended mechanical life of 1,000,000 cycles compared to 100,000 cycles for the MJTP1140, making it suitable for high-cycle-count applications. Contact rating, switch travel, and operating temperature range are comparable. Trade-offs include larger outline dimensions (6.20mm x 6.20mm) and different actuator heights (2.50mm).

Q: Which substitute part provides the closest physical and electrical match to the MJTP1140?

A: The E-Switch TL3313AF160QG provides the closest match, with identical contact rating (0.05A @ 12VDC), actuator height (1.50mm), switch travel (0.25mm), mechanical life (100,000 cycles), and operating temperature range (-20°C ~ 70°C). The primary difference is outline dimensions (4.80mm x 4.80mm versus 4.20mm x 4.20mm) and operating force (160gf versus 260gf).

Q: Are all substitute parts RoHS3 compliant?

A: The MJTP1140, Bourns 7914G series, and E-Switch TL3313AF160QG are ROHS3 compliant. The TE Connectivity FSM2 series carries RoHS compliance designation. All parts are MSL 1 rated with unlimited moisture sensitivity level.

Q: What packaging options are available for these substitute parts?

A: MJTP1140 is supplied in Bulk packaging. Bourns 7914G variants are available in Tube (7914G-1-000), Cut Tape & Digi-Reel (7914G-1-000E, 7914G-1-032E), and Tape & Reel (7914G-1-024E) formats. TE Connectivity FSM2 series and E-Switch TL3313AF160QG are supplied in Tape & Reel packaging.

Q: Can the Bourns 7914G-1-024E flush actuator variant be used in space-constrained applications?

A: The 7914G-1-024E features a 2.62mm actuator height, which is lower than the standard 7914G variants (4.19mm) but higher than the MJTP1140 (1.50mm). This variant is suitable for applications requiring reduced actuator profile while maintaining the larger 5.00mm x 5.00mm footprint of the 7914G series.

Q: What is the difference between FSM2JELGLTR and FSM2JELGXLTR?

A: Both parts are electrically and mechanically identical except for operating force: FSM2JELGLTR operates at 100gf while FSM2JELGXLTR operates at 50gf. Selection depends on the required actuation force for the specific user interface application.
