Substitute Part Grouping Explanation

Substitution eligibility for the EP11SD1ALE is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO topology
• Current rating: 1A (AC/DC)
• Voltage ratings: 120V AC and 28V DC minimum
• Mounting configuration: Through hole, right angle orientation
• Actuator type: Round plunger
• Termination style: PC pin
• Ingress protection: IP57 minimum
• Operating temperature range: -30°C to 85°C
• Electrical life: 60,000 cycles minimum
• RoHS and REACH compliance status

The EP11SD1ARE qualifies as a direct substitute based on identical electrical specifications, mechanical configuration, and environmental ratings. The primary distinction is product status: EP11SD1ARE is active production, whereas EP11SD1ALE is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EP11SD1ARE is the appropriate substitute for EP11SD1ALE applications. Both components maintain identical electrical and mechanical specifications, ensuring direct functional equivalence. The EP11SD1ARE offers the advantage of active production status, providing improved long-term availability and supply chain reliability compared to the obsolete EP11SD1ALE. Both parts satisfy ROHS3 and REACH compliance requirements, supporting regulatory continuity in applications subject to environmental standards. Packaging differs between the two variants: EP11SD1ALE is supplied in bulk format, while EP11SD1ARE is supplied in tray packaging. This distinction may affect handling and inventory management procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can EP11SD1ARE be used as a direct replacement for EP11SD1ALE in existing designs?

A: Yes. The EP11SD1ARE is electrically and mechanically equivalent to EP11SD1ALE. All critical parameters—circuit configuration, current and voltage ratings, mounting type, actuator geometry, termination style, and environmental specifications—are identical. The substitute is suitable for direct board-level replacement without design modification.

Q: What is the primary reason for substitution?

A: EP11SD1ALE is obsolete. EP11SD1ARE is the active production equivalent from the same manufacturer and series, ensuring continued component availability and supply chain support.

Q: Are there packaging differences between these parts?

A: Yes. EP11SD1ALE is supplied in bulk packaging, while EP11SD1ARE is supplied in tray packaging. This affects handling and storage procedures but does not alter component functionality or performance characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both EP11SD1ALE and EP11SD1ARE are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for applications subject to environmental and hazardous substance restrictions.

Q: Are the electrical specifications identical?

A: Yes. Both components are rated for 1A at 120V AC and 28V DC, feature SPST-NO circuit topology, and support 60,000 electrical cycles. Operating temperature range, ingress protection rating, and all other electrical parameters are identical.
