MJTP1232A Equivalent & Substitute Parts

Part Overview

The MJTP1232A is a tactile switch manufactured by APEM Inc., classified as SPST-NO (Single Pole Single Throw - Normally Open) with off-momentary function. This through-hole mounted component is rated for 0.05A at 12VDC with a 6.00mm x 6.00mm footprint and 5.00mm actuator height. The part is currently active in production and ROHS3 compliant.

Substitute parts become necessary when the MJTP1232A experiences supply constraints, extended lead times, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications. The following equivalent components maintain functional compatibility through matching circuit topology, contact ratings, mounting style, and physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP1232A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom
• Contact rating: 0.05A @ 12VDC (or higher current capacity)
• 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

Allowable Variation Parameters:

• Actuator height: ±0.70mm from 5.00mm baseline
• Operating force: Within 160gf ±30gf range
• Operating temperature: Must encompass -20°C to 70°C minimum
• Product status: Active or Obsolete (both acceptable for substitution)

The substitute parts listed below meet these criteria and are directly interchangeable in circuit applications requiring SPST-NO momentary tactile switching at 0.05A 12VDC with standard through-hole PCB mounting.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

TLE1105AF160Q and TLE1105F160Q (E-Switch) are the preferred alternatives. Both maintain identical electrical specifications (0.05A @ 12VDC), circuit topology (SPST-NO), and mechanical life (100,000 cycles). TLE1105AF160Q matches the 5.00mm actuator height exactly. TLE1105F160Q operates at 4.30mm height, introducing a 0.70mm reduction that remains within acceptable tolerance for most PCB layouts. Both are ROHS3 compliant and currently active in production.

PTS645TL50-2 LFS (C&K) provides full electrical and mechanical equivalence with identical contact rating and actuator height. The 130gf operating force represents a 30gf reduction from the MJTP1232A baseline but remains functionally compatible. This part offers extended operating temperature range (-40°C ~ 85°C) and is ROHS3 compliant and active.

Secondary Substitute (Limited Application):

EVQ-PBE05R (Panasonic) is electrically rated at 0.02A @ 15VDC, which is lower than the MJTP1232A specification of 0.05A @ 12VDC. This part is suitable only for applications where actual circuit current draw does not exceed 0.02A. The part is obsolete and should be considered only when supply of primary alternatives is unavailable. RoHS compliance is confirmed.

Compliance Verification:

All substitute parts maintain ROHS3 compliance (or equivalent RoHS compliance for EVQ-PBE05R) and MSL 1 rating, ensuring compatibility with standard PCB assembly processes. ECCN and HTSUS classifications are consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can TLE1105F160Q be used as a direct replacement for MJTP1232A despite the 4.30mm actuator height?

A: Yes. The 0.70mm height reduction falls within acceptable mechanical tolerance for standard through-hole PCB applications. Verify that the reduced actuator height does not conflict with enclosure clearances or user interface requirements in your specific design.

Q: Is EVQ-PBE05R suitable for all MJTP1232A applications?

A: No. EVQ-PBE05R is rated for 0.02A @ 15VDC, compared to MJTP1232A at 0.05A @ 12VDC. Use EVQ-PBE05R only in circuits where the actual current draw does not exceed 0.02A. Additionally, this part is obsolete and should not be selected for new designs.

Q: What is the significance of the 130gf operating force on PTS645TL50-2 LFS?

A: The 130gf force is 30gf lower than the MJTP1232A baseline of 160gf. This results in slightly easier actuation. For applications where consistent tactile feedback and actuation force are critical, verify that the reduced force meets user interface requirements.

Q: Are all substitute parts available in the same packaging as MJTP1232A?

A: Yes. All listed substitutes are supplied in bulk packaging, matching the MJTP1232A packaging specification. Confirm specific packaging quantities with your supplier.

Q: Which substitute offers the widest operating temperature range?

A: PTS645TL50-2 LFS operates across -40°C ~ 85°C, compared to -20°C ~ 70°C for MJTP1232A and other E-Switch alternatives. Select this part for applications requiring extended temperature performance.

Q: Can I use multiple substitute parts interchangeably within the same production run?

A: TLE1105AF160Q, TLE1105F160Q, and PTS645TL50-2 LFS are mechanically and electrically interchangeable and can be used interchangeably. EVQ-PBE05R should not be mixed with other substitutes due to its lower current rating and obsolete status.
