MJS22 Equivalent & Substitute Parts

Part Overview

The MJS22 is a slide switch manufactured by APEM Inc., configured as a Double Pole Double Throw (DPDT) switch with On-On functionality. It is rated for 100mA DC at 12V and features through-hole PC pin termination with silver contact finish. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MJS22 is determined by the following critical parameters: circuit configuration (DPDT), switch function (On-On), mounting type (through hole), and termination style (PC pin). The substitute parts listed maintain these core functional characteristics.

Substitutes are grouped into two categories based on electrical ratings:

Direct Electrical Equivalents (100mA DC at 12V):

• EG2209 (E-Switch): Matches current and voltage ratings exactly with identical actuator length and switch travel specifications.

Higher-Rated Alternatives (Suitable for 12V applications with margin):

• SSB22 (TE Connectivity ALCOSWITCH): Rated for 100mA DC at 30V with equivalent mechanical specifications, providing voltage headroom for 12V operation.
• 1825010-1 (TE Connectivity ALCOSWITCH): Rated for 300mA AC at 115V; suitable where higher current capacity is required.
• 1825010-2 (TE Connectivity ALCOSWITCH): Rated for 0.4VA AC/DC at 20V; suitable for low-power AC/DC applications.

All substitute parts maintain DPDT configuration, On-On function, through-hole mounting, PC pin termination, and ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Choice): EG2209 is the preferred substitute. It matches the MJS22 in current rating (100mA DC), voltage rating (12V), actuator length (2.00mm), and switch travel (2.00mm). Both parts are ROHS3 compliant and maintain active product status. This part provides the closest functional and mechanical equivalence.

For Applications Requiring Voltage Margin: SSB22 is suitable for 12V DC applications where additional voltage headroom is beneficial. It maintains 100mA DC current rating, identical switch travel (2.00mm), and ROHS3 compliance. The actuator length is 4.60mm, which may require PCB layout verification. Operating force is comparable (250gf vs. 225gf).

For Higher Current or AC Applications: 1825010-1 and 1825010-2 are suitable only where application requirements exceed the MJS22 specifications. 1825010-1 supports 300mA AC at 115V for AC-rated circuits. 1825010-2 supports 0.4VA AC/DC at 20V for low-power mixed-signal applications. Both feature higher operating force (950gf) and extended temperature range (-40°C to 80°C).

All substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the original MJS22.

Frequently Asked Questions (FAQ)

Q: Can EG2209 be used as a direct replacement for MJS22? A: Yes. EG2209 matches the MJS22 in circuit configuration (DPDT), switch function (On-On), current rating (100mA DC), voltage rating (12V), actuator length (2.00mm), and switch travel (2.00mm). Both are ROHS3 compliant. Mechanical fit and electrical performance are equivalent.

Q: What is the difference between SSB22 and EG2209? A: Both are suitable for 12V DC applications at 100mA. SSB22 is rated for 30V DC, providing voltage margin. SSB22 has a longer actuator (4.60mm vs. 2.00mm) and higher operating force (250gf vs. unspecified for EG2209). SSB22 features epoxy sealed terminals. EG2209 matches the original MJS22 actuator dimensions more closely.

Q: Are the TE Connectivity ALCOSWITCH parts (1825010-1, 1825010-2, SSB22) interchangeable? A: No. These parts have different electrical ratings and are not interchangeable. 1825010-1 is rated for 300mA AC at 115V. 1825010-2 is rated for 0.4VA AC/DC at 20V. SSB22 is rated for 100mA DC at 30V. Selection depends on application voltage and current requirements.

Q: Does actuator length affect PCB compatibility? A: Yes. The MJS22 and EG2209 both have 2.00mm actuator length. SSB22 has 4.60mm actuator length, and 1825010-1 and 1825010-2 have 2.79mm actuator length. Verify PCB cutout and mechanical clearance specifications before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. EG2209, SSB22, 1825010-1, and 1825010-2 are all ROHS3 compliant, matching the MJS22 regulatory status.

Q: What is the difference between silver and gold contact finish? A: MJS22, EG2209, SSB22, and 1825010-1 feature silver contact finish. 1825010-2 features gold contact finish. Gold provides enhanced corrosion resistance in high-humidity or corrosive environments. Silver is suitable for standard industrial applications.

Q: Can I use a higher-rated substitute in a 12V application? A: Yes, if the application circuit is designed for the substitute part's specifications. SSB22 (30V DC rating) is suitable for 12V applications. 1825010-1 (115V AC) and 1825010-2 (20V AC/DC) are suitable only if the application circuit operates at their respective voltage and current ratings.
