EP12SD1CLE Equivalent & Substitute Parts

Part Overview

The EP12SD1CLE is a pushbutton switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuit configuration with 1A current rating at 120V AC / 28V DC. This through-hole mounted component is designed for standard applications requiring momentary switching action with IP57 ingress protection. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The EP12SD1CRE qualifies as a direct substitute for the EP12SD1CLE based on the following critical parameters:

Electrical Compatibility:

• Identical SPDT circuit configuration
• Matching current rating of 1A (AC/DC)
• Identical voltage ratings: 120V AC and 28V DC
• Same switch function: On-Mom (momentary action)
• Equivalent electrical life: 30,000 cycles

Mechanical Compatibility:

• Same mounting type: Through Hole
• Identical actuator type: Round, Plunger
• Matching termination style: PC Pin
• Same ingress protection rating: IP57

Environmental & Compliance:

• Identical operating temperature range: -30°C to 85°C
• Both RoHS compliant (ROHS3 for main part, RoHS for substitute)
• Same REACH status: REACH Unaffected
• Identical ECCN and HTSUS classifications

The EP12SD1CRE maintains all functional and physical parameters required for direct substitution, with the primary distinction being active product status versus obsolete status of the original part.

Engineering Selection Recommendations

The EP12SD1CRE is the appropriate substitute for the obsolete EP12SD1CLE. Selection is based on:

Product Availability: The EP12SD1CLE is obsolete with no ongoing manufacturing. The EP12SD1CRE is an active product with current inventory availability (960 pcs in stock), ensuring reliable procurement for new designs and system maintenance.

Compliance Alignment: Both parts maintain equivalent regulatory compliance. The EP12SD1CRE carries RoHS compliance certification, meeting current environmental standards. Both parts are REACH unaffected and classified as EAR99 for export control purposes.

Functional Equivalence: All electrical and mechanical parameters are identical, including circuit topology, current and voltage ratings, switching characteristics, and environmental operating range. The parts are physically and functionally interchangeable.

Certification Status: Both components maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can EP12SD1CRE be used as a direct replacement for EP12SD1CLE in existing designs?

A: Yes. The EP12SD1CRE is electrically and mechanically equivalent to the EP12SD1CLE. All critical parameters—circuit configuration, current and voltage ratings, switching function, mounting type, and environmental specifications—are identical. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The EP12SD1CLE is obsolete and no longer manufactured. The EP12SD1CRE is the active equivalent from the same manufacturer and series, with identical specifications and current availability.

Q: Are there any packaging differences between EP12SD1CLE and EP12SD1CRE?

A: The EP12SD1CLE was supplied in standard packaging, while the EP12SD1CRE is available in bulk packaging. This difference does not affect component functionality or performance.

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. Both parts use identical through-hole PC pin termination and round plunger actuator configuration. PCB layouts and assembly procedures remain unchanged.

Q: What is the electrical life expectancy for the EP12SD1CRE?

A: The EP12SD1CRE is rated for 30,000 electrical cycles, matching the specification of the original EP12SD1CLE.

Q: Are there any compliance or certification differences?

A: Both parts meet current environmental and regulatory standards. The EP12SD1CRE carries RoHS compliance certification. Both are REACH unaffected and classified as EAR99 for export purposes.

Q: What is the operating temperature range for the EP12SD1CRE?

A: The operating temperature range is -30°C to 85°C, identical to the EP12SD1CLE.
