MX3A-L1JW Equivalent & Substitute Parts

Part Overview

The MX3A-L1JW is a pushbutton switch manufactured by Cherry Americas LLC, classified as a SPST-NO (Single Pole Single Throw - Normally Open) keyswitch with through-hole mounting. This component is designed for applications requiring momentary contact switching with a 10mA current rating at 12V AC/DC. The product is currently listed as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MX3A-L1JW is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Current rating: 10mA (AC/DC)
• Voltage rating: 12V AC and 12V DC
• Actuator type: Plunger for Cap
• Actuator color: Red
• Termination style: PC Pin
• Mounting type: Through Hole
• Ingress protection: IP40
• Operating temperature range: -10°C to 70°C
• Mechanical life: 50,000,000 cycles
• Series: MX

The MX3A-L1NW meets all these criteria and is classified as a direct substitute. The primary distinction is product status: MX3A-L1NW is active production, whereas MX3A-L1JW is obsolete. Packaging differs (MX3A-L1NW supplied in bulk versus MX3A-L1JW standard packaging), but this does not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The MX3A-L1NW is the direct substitute for the obsolete MX3A-L1JW. Both components share identical electrical and mechanical specifications across all functional parameters. The MX3A-L1NW carries active product status and ROHS3 compliance certification, providing assurance of ongoing availability and regulatory alignment. For applications currently using MX3A-L1JW, transition to MX3A-L1NW requires no circuit redesign or application modification. The component is pin-compatible and functionally equivalent in all operating conditions within the specified temperature and voltage ranges.

Frequently Asked Questions (FAQ)

Q: Can MX3A-L1NW be used as a direct replacement for MX3A-L1JW in existing designs?

A: Yes. Both components are electrically and mechanically identical across all functional parameters including circuit configuration, current rating, voltage rating, actuator type, and termination style. No circuit modification is required.

Q: What is the difference between MX3A-L1JW and MX3A-L1NW?

A: The primary differences are product status (MX3A-L1JW is obsolete; MX3A-L1NW is active production) and packaging format (bulk packaging for MX3A-L1NW). Functional specifications are identical.

Q: Are there any compliance differences between these parts?

A: Both components are RoHS compliant. MX3A-L1NW carries ROHS3 certification, representing the current regulatory standard. Both meet MSL 1 (Unlimited) moisture sensitivity requirements.

Q: Does packaging format affect component performance?

A: No. Packaging format (bulk versus standard) does not affect electrical or mechanical performance. Component specifications and functionality remain identical regardless of packaging configuration.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by matching circuit configuration (SPST-NO), switch function (Off-Mom), current rating (10mA AC/DC), voltage rating (12V AC/DC), actuator type (Plunger for Cap), termination style (PC Pin), mounting type (Through Hole), and operating temperature range (-10°C to 70°C).
