EP12SD1AME Equivalent & Substitute Parts

Part Overview

The EP12SD1AME is a pushbutton switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 120V AC. This through-hole, right-angle mounted component is designed for standard applications requiring momentary switching action with IP57 ingress protection. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the EP12SD1AME is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary action)
• 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: 30,000 cycles

The EP12SD1ASE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The EP12SD1ASE is the qualified substitute for the obsolete EP12SD1AME. Both components share identical electrical specifications, mechanical configuration, and environmental ratings. The EP12SD1ASE maintains active product status with C&K, ensuring continued availability and supply chain reliability. Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

Selection between these parts should be based on packaging requirements and procurement logistics. The EP12SD1AME was supplied in bulk packaging, while the EP12SD1ASE is available in tray packaging. For applications requiring the original bulk format, the EP12SD1ASE can be sourced and repackaged according to system assembly procedures.

Frequently Asked Questions (FAQ)

Q: Can EP12SD1ASE directly replace EP12SD1AME in existing designs?

A: Yes. The EP12SD1ASE is electrically and mechanically equivalent to the EP12SD1AME. All functional parameters, voltage ratings, current capacity, and environmental specifications are identical. Direct substitution is supported without circuit or mechanical redesign.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging. The EP12SD1AME is obsolete and was supplied in bulk packaging. The EP12SD1ASE is an active product available in tray packaging. All electrical and mechanical characteristics are identical.

Q: Are there any compliance differences between the parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance status is equivalent.

Q: Does packaging affect electrical performance?

A: No. Packaging format (bulk versus tray) does not affect component performance, electrical ratings, or mechanical function. Selection should be based on assembly and procurement requirements.

Q: What is the base product number for these parts?

A: The base product number is EP12SD1, which identifies the core switch design within the C&K EP series. Suffix designations (AME, ASE) indicate packaging and configuration variants.
