Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EP11SD1AME is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 1A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Through Hole, Right Angle
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Ingress protection: IP57
• Operating temperature range: -30°C to 85°C
• Electrical life: 60,000 cycles

The EP11SD1ASE qualifies as a direct substitute based on complete alignment with all critical electrical and mechanical parameters. The primary distinction is product status: EP11SD1ASE is active and available, whereas EP11SD1AME is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EP11SD1ASE is the direct equivalent for EP11SD1AME applications. Both components share identical electrical and mechanical specifications, with the primary distinction being product lifecycle status. EP11SD1ASE is currently in active production, ensuring long-term availability and supply chain stability.

Both parts maintain equivalent compliance certifications: RoHS compliance and REACH unaffected status. The EP11SD1ASE is designated as RoHS Compliant, while the EP11SD1AME carries RoHS3 Compliant status; both satisfy modern regulatory requirements for electronic component procurement.

For new designs or component replenishment, EP11SD1ASE is the appropriate selection due to its active status and confirmed availability. For legacy system maintenance where EP11SD1AME is currently installed, EP11SD1ASE provides functional and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can EP11SD1ASE be used as a direct replacement for EP11SD1AME?

A: Yes. Both components are electrically and mechanically identical across all critical parameters: SPST-NO circuit, 1A current rating, 120V AC / 28V DC voltage ratings, through-hole right-angle mounting, round plunger actuator, PC pin termination, IP57 ingress protection, and -30°C to 85°C operating temperature range.

Q: What is the primary reason to transition from EP11SD1AME to EP11SD1ASE?

A: EP11SD1AME is obsolete. EP11SD1ASE is an active product with confirmed manufacturing and supply availability, making it the appropriate choice for ongoing procurement and new designs.

Q: Are there packaging differences between these parts?

A: EP11SD1AME packaging is listed as standard through-hole format. EP11SD1ASE is supplied in bulk packaging. Both maintain identical component specifications and mounting characteristics.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. Both EP11SD1AME and EP11SD1ASE are RoHS compliant and REACH unaffected, satisfying current regulatory requirements for electronic component use.

Q: What is the electrical life specification for these switches?

A: Both components are rated for 60,000 electrical cycles, providing equivalent operational durability across momentary switch applications.
