Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped based on maintained electrical and mechanical compatibility within the SPST-NO tactile switch category. The primary substitution criteria are:

Core Compatibility Parameters:

• Circuit configuration: SPST-NO maintained across all substitutes
• Switch function: Off-Mom maintained across all substitutes
• Mounting type: Surface Mount maintained across all substitutes
• Actuator orientation: Top Actuated maintained across all substitutes
• Termination style: Gull Wing maintained across all substitutes
• RoHS3 compliance: Maintained across all substitutes

Allowed Variation Parameters:

• Contact rating voltage and current (0.05A @ 12VDC to 0.1A @ 16VDC)
• Operating temperature range (-55°C ~ 125°C extended capability)
• Actuator height (2.00mm to 4.19mm)
• Operating force (160gf to 300gf)
• Mechanical life (100,000 to 1,000,000 cycles)
• Outline dimensions (5.00mm x 5.00mm to 6.20mm x 6.20mm)
• Packaging format (Tape & Reel, Cut Tape, Tube, Bulk)
• Ingress protection (standard to IP67)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, qualifying them for direct substitution within the SPST-NO tactile switch category.

Bourns 7914G Series (7914G-1-000, 7914G-1-000E, 7914G-1-024E, 7914G-1-032E): These parts provide higher contact rating (0.1A @ 16VAC/DC), extended operating temperature range (-55°C ~ 125°C), and IP67 ingress protection. Outline dimensions are reduced to 5.00mm x 5.00mm. Actuator height varies from 2.62mm to 4.19mm depending on variant. Operating force increases to 300gf. Packaging options include Tube, Cut Tape & Digi-Reel, and Tape & Reel formats.

TE Connectivity FSM1JELGTR: This part maintains identical contact rating (0.05A @ 12VDC) and outline dimensions (6.20mm x 6.20mm) as the MJTP1122BTR. Operating force matches at 160gf. Mechanical life extends to 1,000,000 cycles. Actuator height reduces to 2.00mm. Operating temperature range extends to -35°C ~ 85°C. Packaging is Tape & Reel format.

TE Connectivity FSM1LPAS: This part maintains outline dimensions (6.20mm x 6.00mm) and actuator height (3.10mm) similar to the MJTP1122BTR. Contact rating increases to 0.05A @ 24VDC. Operating force increases to 260gf. Mechanical life extends to 1,000,000 cycles. Operating temperature range extends to -40°C ~ 105°C. Packaging is Bulk format. This part includes a grounding pin feature.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 7914G series replace the MJTP1122BTR in all applications?

A: The Bourns 7914G series maintains SPST-NO circuit configuration, surface mount mounting, top actuated orientation, and gull wing termination. However, outline dimensions reduce from 6.20mm x 6.20mm to 5.00mm x 5.00mm, and operating force increases from 160gf to 300gf. PCB layout and actuator force requirements must be verified before substitution.

Q: What is the primary difference between FSM1JELGTR and FSM1LPAS?

A: FSM1JELGTR maintains the 0.05A @ 12VDC contact rating with 2.00mm actuator height and Tape & Reel packaging. FSM1LPAS increases contact rating to 0.05A @ 24VDC, maintains 3.10mm actuator height, and uses Bulk packaging with an additional grounding pin feature.

Q: Are all substitute parts suitable for extended temperature applications?

A: The Bourns 7914G series supports -55°C ~ 125°C. FSM1JELGTR supports -35°C ~ 85°C. FSM1LPAS supports -40°C ~ 105°C. The original MJTP1122BTR operates -20°C ~ 70°C. Application temperature requirements must be matched to the appropriate substitute.

Q: Which substitute offers the longest mechanical life?

A: FSM1JELGTR and FSM1LPAS both provide 1,000,000 cycle mechanical life, compared to 100,000 cycles for the MJTP1122BTR and all Bourns 7914G variants.

Q: Do any substitutes provide ingress protection?

A: All Bourns 7914G variants (7914G-1-000, 7914G-1-000E, 7914G-1-024E, 7914G-1-032E) feature IP67 ingress protection. The MJTP1122BTR, FSM1JELGTR, and FSM1LPAS do not specify ingress protection ratings.

Q: What packaging options are available for high-volume production?

A: Tape & Reel packaging is available for MJTP1122BTR, 7914G-1-024E, and FSM1JELGTR. Cut Tape & Digi-Reel packaging is available for 7914G-1-000E and 7914G-1-032E. Tube packaging is available for 7914G-1-000. Bulk packaging is available for FSM1LPAS.
