Key Parameters

Substitute Part Grouping Explanation

Substitution of the MX1A-E1DW is determined by strict alignment of the following critical parameters:

• Circuit configuration: SPST-NO topology
• Switch function: Momentary (Off-Mom) operation
• Current rating: 10mA maximum
• Voltage rating: 12V AC/DC
• Mounting type: Through hole with PC pin termination
• Actuator type: Plunger configuration
• Operating temperature range: -40°C to 70°C minimum
• Mechanical life: 50,000,000 cycles minimum

The MX1A-E1NW has been identified as a functionally equivalent substitute based on these core electrical and mechanical parameters. Both components share identical circuit topology, current and voltage ratings, mounting configuration, and mechanical durability specifications.

Parameter Comparison

Engineering Selection Recommendations

The MX1A-E1NW serves as an active substitute for the obsolete MX1A-E1DW based on functional equivalence in circuit topology and switch operation. However, the following compliance considerations apply:

The MX1A-E1DW is RoHS compliant, while the MX1A-E1NW is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this difference in material composition and environmental restrictions.

Both components carry EAR99 export classification. The MX1A-E1NW includes REACH status information available upon request from the manufacturer.

Selection between these parts should be based on regulatory compliance requirements of the target application and supply chain availability, as the MX1A-E1DW is obsolete and the MX1A-E1NW is currently in active production.

Frequently Asked Questions (FAQ)

Q: Can the MX1A-E1NW directly replace the MX1A-E1DW in existing designs?

A: The MX1A-E1NW is functionally equivalent in circuit topology and switch operation. However, the RoHS compliance difference must be evaluated against application requirements. Physical dimensions and pin configuration should be confirmed with manufacturer datasheets before implementation.

Q: What is the primary reason for seeking a substitute for the MX1A-E1DW?

A: The MX1A-E1DW is classified as obsolete. The MX1A-E1NW is an active product currently in production, making it available for new procurement and ongoing supply chain requirements.

Q: Are there electrical parameter differences between these parts?

A: Both components share SPST-NO circuit configuration and momentary switch function. Complete electrical specifications for the MX1A-E1NW (current rating, voltage rating, temperature range, mechanical life) should be obtained from the manufacturer to confirm full parameter alignment.

Q: What packaging options are available?

A: The MX1A-E1DW packaging specification is not provided. The MX1A-E1NW is available in bulk packaging.

Q: How do RoHS compliance differences affect component selection?

A: RoHS compliance is a regulatory requirement in specific markets and applications. The MX1A-E1DW is RoHS compliant; the MX1A-E1NW is not. Applications subject to RoHS directives must use the compliant component or identify an alternative that meets both functional and regulatory requirements.
