MJTP1109 Equivalent & Substitute Parts

Part Overview

The MJTP1109 is an active SPST-NO tactile switch manufactured by APEM Inc., designed for through-hole mounting with top actuation. This component operates at 0.05A @ 12VDC and provides tactile feedback with a 200gf operating force. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturer offerings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP1109 is determined by the following critical parameters:

• Electrical Compatibility: Circuit configuration (SPST-NO) and contact rating (0.05A @ 12VDC) must be identical
• Mechanical Compatibility: Through-hole mounting, top actuation, and 5.00mm actuator height off PCB must be maintained
• Termination: PC pin termination required for direct PCB compatibility
• Reliability: Mechanical life rating of 100,000 cycles minimum
• Regulatory Compliance: ROHS3 compliance and MSL 1 rating required

The PTS645TL50-2 LFS from C&K meets all critical substitution criteria. While outline dimensions differ (6.00mm x 6.00mm vs. 7.20mm x 7.20mm) and operating force varies (130gf vs. 200gf), these parameters fall within acceptable tolerance for equivalent functional performance in the specified electrical and mechanical application space.

Parameter Comparison

Engineering Selection Recommendations

Both the MJTP1109 and PTS645TL50-2 LFS are active products with identical regulatory compliance profiles. The MJTP1109 maintains current production status with 1014 units in stock, while the PTS645TL50-2 LFS offers higher inventory availability at 4479 units. Both components satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

The PTS645TL50-2 LFS provides an extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C), which may offer additional thermal margin in applications requiring broader environmental tolerance. Selection between these parts should be based on inventory requirements, thermal operating envelope, and specific PCB layout constraints related to outline dimensions.

Frequently Asked Questions (FAQ)

Q: Can the PTS645TL50-2 LFS directly replace the MJTP1109 in existing designs?

A: Direct replacement is electrically and mechanically compatible. Both components share identical circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), actuator height (5.00mm), and termination style (PC Pin). PCB layout verification is required due to outline dimension differences (6.00mm x 6.00mm vs. 7.20mm x 7.20mm).

Q: What are the key differences between these two parts?

A: Primary differences include outline dimensions, operating force (130gf vs. 200gf), and operating temperature range. The PTS645TL50-2 LFS features a grounding pin and operates across a wider temperature spectrum (-40°C ~ 85°C). Both maintain 100,000 cycle mechanical life and identical electrical ratings.

Q: Are both parts RoHS compliant?

A: Yes. Both the MJTP1109 and PTS645TL50-2 LFS are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should be selected for high-temperature applications?

A: The PTS645TL50-2 LFS supports operation to 85°C, compared to the MJTP1109 maximum of 70°C. Application thermal requirements should determine selection.

Q: Are there packaging or supply chain considerations?

A: The PTS645TL50-2 LFS offers significantly higher inventory availability (4479 units vs. 1014 units). Both are supplied in bulk packaging.
