MJTP1232E Equivalent & Substitute Parts

Part Overview

The MJTP1232E is an active SPST-NO tactile switch manufactured by APEM Inc., designed for through-hole mounting applications requiring low-current switching at 12VDC. This component is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). The part is specified for applications demanding tactile feedback with 100,000 mechanical life cycles. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and compliance certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MJTP1232E is determined by the following mandatory parameters:

• Electrical Compatibility: Circuit configuration (SPST-NO), contact rating (0.05A @ 12VDC), and switch function (Off-Mom) must be identical
• Mechanical Compatibility: Through-hole mounting, top actuated orientation, PC pin termination, and 6.00mm x 6.00mm outline dimensions must match
• Reliability: Mechanical life rating of 100,000 cycles minimum
• Compliance: ROHS3 compliance and active product status required

The identified substitute parts PTS645TK70-2 LFS and PTS645TM70-2 LFS from C&K satisfy all mandatory electrical and mechanical parameters. Variations in operating force, actuator height, and operating temperature range do not preclude substitution when the core switching characteristics and physical form factor remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both C&K substitute parts maintain active product status and ROHS3 compliance, meeting regulatory requirements equivalent to the MJTP1232E. PTS645TM70-2 LFS is the primary substitute, offering identical operating force (160gf) to the original part while providing extended operating temperature range (-40°C ~ 85°C versus -20°C ~ 70°C). PTS645TK70-2 LFS is a secondary substitute with higher operating force (260gf), suitable for applications where increased actuation resistance is acceptable or beneficial. Both C&K parts feature grounding pins and polyamide actuator material, providing additional design flexibility. Selection between substitutes depends on application-specific requirements for operating force and temperature range.

Frequently Asked Questions (FAQ)

Q: Can PTS645TK70-2 LFS replace MJTP1232E in all applications?

A: PTS645TK70-2 LFS is electrically and mechanically compatible as a substitute. The primary difference is operating force (260gf versus 160gf). Applications sensitive to actuation force require evaluation of this parameter against design specifications.

Q: What is the difference between PTS645TK70-2 LFS and PTS645TM70-2 LFS?

A: Both parts are C&K PTS645 series switches with identical electrical ratings and physical dimensions. The distinction is operating force: PTS645TK70-2 LFS requires 260gf, while PTS645TM70-2 LFS requires 160gf (matching the original MJTP1232E). Both provide extended temperature range (-40°C ~ 85°C).

Q: Are there PCB layout considerations when substituting these parts?

A: All three parts share identical outline dimensions (6.00mm x 6.00mm) and PC pin termination. Actuator height varies slightly (MJTP1232E: 7.30mm; C&K parts: 7.00mm), which may affect clearance in confined spaces. Verify mechanical clearance in your specific application.

Q: Do substitute parts maintain the same compliance certifications?

A: All parts are ROHS3 compliant with REACH Unaffected status and EAR99 ECCN classification. Moisture sensitivity level (MSL 1 - Unlimited) is identical across all three parts.

Q: What inventory levels are available for these substitutes?

A: MJTP1232E: 957 Pcs; PTS645TK70-2 LFS: 10,485 Pcs; PTS645TM70-2 LFS: 6,949 Pcs.
