Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MJTP1230G are categorized based on the following critical parameters that determine functional interchangeability:

Primary Substitution Criteria:

• Circuit configuration (SPST-NO)
• Contact rating voltage (12VDC nominal)
• Contact current rating (0.05A)
• Switch function (Off-Mom momentary operation)
• Mounting type (Through Hole)
• Actuator orientation (Top Actuated)
• Outline dimensions (6.00mm x 6.00mm)
• Termination style (PC Pin)
• Mechanical life (100,000 cycles minimum)

Substitute Categories:

Category 1: Direct Electrical & Mechanical Equivalents Parts matching all primary criteria with identical or compatible operating force and temperature ranges. These parts provide pin-for-pin and functional compatibility.

Category 2: Voltage-Rated Variants Parts with identical mechanical and electrical specifications but rated for higher voltage (24VDC). These parts are electrically compatible in 12VDC applications due to voltage derating principles.

Category 3: Operating Force Variants Parts with identical electrical specifications and form factors but different operating force ratings. These parts maintain functional compatibility with variations in actuation force.

Category 4: Non-Equivalent Parts Parts with different circuit topologies, mounting types, or current ratings that do not provide direct substitution but are listed in the original part's substitute reference.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Pin-for-Pin Compatible):

The TL1105FF160Q manufactured by E-Switch provides complete electrical and mechanical equivalence to the MJTP1230G. Both parts share identical contact ratings (0.05A @ 12VDC), operating force (160gf), switch travel (0.25mm), actuator height (7.00mm), outline dimensions (6.00mm x 6.00mm), and mechanical life (100,000 cycles). Both are ROHS3 compliant with MSL 1 rating. The operating temperature range of the TL1105FF160Q (-20°C ~ 70°C) matches the MJTP1230G specification. This part is suitable for direct substitution without circuit modification.

Voltage-Rated Substitute (Electrically Compatible):

The 1-1825910-0 manufactured by TE Connectivity ALCOSWITCH Switches is rated for 0.05A @ 24VDC but maintains identical mechanical specifications to the MJTP1230G (7.00mm actuator height, 6.00mm x 6.00mm outline, 160gf operating force, 0.25mm switch travel, 100,000 mechanical cycles). This part is electrically compatible in 12VDC applications through voltage derating. The extended operating temperature range (-40°C ~ 105°C) provides broader environmental capability. Both parts are ROHS3 compliant with MSL 1 rating. This part is suitable for substitution in applications where extended temperature performance is beneficial.

Operating Force Variants (Functionally Compatible):

The PTS645SH70-2 LFS, PTS645SK70-2 LFS, and PTS645SL702 LFS manufactured by C&K are all rated for 0.05A @ 12VDC with identical mechanical form factors (7.00mm actuator height, 6.00mm x 6.00mm outline, through-hole PC pin termination, 100,000 mechanical cycles). These parts differ only in operating force: 200gf, 260gf, and 130gf respectively, compared to the MJTP1230G's 160gf. All three are ROHS3 compliant with MSL 1 rating and extended operating temperature range (-40°C ~ 85°C). These parts are suitable for substitution when different actuation force characteristics are acceptable or required by the application.

Non-Equivalent Parts (Not Recommended for Direct Substitution):

The HDT0204 (C&K) is a surface-mount detector switch with 1mA @ 5V rating and 35gf operating force. This part does not provide electrical or mechanical compatibility due to different mounting type, voltage rating, current rating, and actuator type.

The SDA01H0BD and TDA08H0SB1 (both C&K) are DIP switches with 25mA @ 24V rating and significantly lower mechanical life (1,000 cycles). These parts do not provide functional equivalence due to different circuit topology, current rating, and mechanical life specification.

Frequently Asked Questions (FAQ)

Q: Can the TL1105FF160Q be used as a direct replacement for the MJTP1230G?

A: Yes. The TL1105FF160Q provides complete pin-for-pin and functional compatibility. Both parts share identical electrical specifications (0.05A @ 12VDC), mechanical parameters (7.00mm height, 6.00mm x 6.00mm outline, 160gf operating force, 0.25mm travel), and lifecycle ratings (100,000 cycles). No circuit modification is required.

Q: Is the 1-1825910-0 suitable for a 12VDC application despite its 24VDC rating?

A: Yes. The 1-1825910-0 is electrically compatible in 12VDC applications. A 24VDC-rated contact can safely operate at lower voltages through voltage derating. The mechanical specifications (7.00mm height, 6.00mm x 6.00mm outline, 160gf operating force, 0.25mm travel) are identical to the MJTP1230G. The extended temperature range (-40°C ~ 105°C) provides additional environmental capability.

Q: What is the difference between the PTS645 series variants?

A: The PTS645SH70-2 LFS, PTS645SK70-2 LFS, and PTS645SL702 LFS differ only in operating force: 200gf, 260gf, and 130gf respectively. All other electrical and mechanical specifications match the MJTP1230G (0.05A @ 12VDC, 7.00mm height, 6.00mm x 6.00mm outline, 100,000 cycles). Selection depends on required actuation force for the application.

Q: Can the HDT0204 replace the MJTP1230G?

A: No. The HDT0204 is not suitable for direct substitution. It is a surface-mount detector switch with significantly different electrical specifications (1mA @ 5V versus 0.05A @ 12VDC), different mounting type (surface mount versus through hole), and different actuator type (angled toggle detector versus standard top actuated). The mechanical and electrical parameters are incompatible.

Q: Are the SDA01H0BD and TDA08H0SB1 equivalent to the MJTP1230G?

A: No. These parts are DIP switches with fundamentally different circuit topology (SPST multi-position versus SPST-NO single momentary), significantly higher current rating (25mA versus 0.05A), and substantially lower mechanical life (1,000 cycles versus 100,000 cycles). These parts do not provide functional equivalence.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected. All parts carry MSL 1 (unlimited moisture sensitivity level) rating. These certifications ensure regulatory compliance across all identified substitutes.

Q: Does packaging format affect substitution compatibility?

A: Packaging format (bulk, tape and reel, or tube) does not affect electrical or mechanical compatibility. The packaging designation indicates the quantity and delivery format only. Component selection should be based on electrical specifications, mechanical parameters, and form factor compatibility, not packaging type.

Q: What is the significance of the 0.25mm switch travel specification?

A: Switch travel defines the distance the actuator moves from the initial position to full contact closure. The 0.25mm specification is a mechanical characteristic that affects tactile feedback and response time. Substitute parts with identical or compatible switch travel ensure consistent user interface behavior and electrical performance.
