EE2-9SNU-L Equivalent & Substitute Parts

Part Overview

The EE2-9SNU-L is a General Purpose Relay manufactured by KEMET, configured as a DPDT (2 Form C) surface mount component with a 9VDC coil voltage and 2A contact rating. This relay is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, production continuity, and component sourcing.

The EE2-9SNU-L operates across a wide temperature range (-40°C to 85°C) and is RoHS3 compliant. Due to its obsolete status, engineers and procurement teams must identify active alternative components that maintain electrical and mechanical compatibility with existing designs.

The substitute part 6-1462037-4 (TE Connectivity Potter & Brumfield Relays) meets all electrical and mechanical compatibility criteria. This part is manufactured by TE Connectivity and carries active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The 6-1462037-4 (TE Connectivity Potter & Brumfield Relays) is the qualified substitute for the obsolete EE2-9SNU-L based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including coil voltage (9VDC), contact form (DPDT), contact rating (2A), switching voltage (250VAC/220VDC), coil current (11.1 mA), and coil resistance (810 Ohms). The must-operate voltage threshold of 6.75 VDC is identical.

Mechanical Compatibility: Both components utilize surface mount technology with gull wing termination, ensuring PCB layout and assembly process compatibility without design modification.

Compliance Status: The substitute part maintains RoHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original component.

Product Status Advantage: The substitute part carries active product status with TE Connectivity, ensuring long-term availability, technical support, and supply chain continuity compared to the obsolete EE2-9SNU-L.

Timing Differences: The substitute exhibits slightly longer operate time (3 ms vs. 2 ms) and release time (3 ms vs. 1 ms). These differences must be evaluated against specific application timing requirements. Applications with strict timing constraints below these thresholds require additional circuit-level analysis.

Environmental Enhancement: The substitute provides hermetic sealing, offering enhanced protection in moisture-sensitive or harsh environments compared to the original component specification.

Frequently Asked Questions (FAQ)

Q: Can the 6-1462037-4 be used as a direct replacement for the EE2-9SNU-L without PCB modifications?

A: Yes. Both components share identical mounting type (surface mount), termination style (gull wing), and footprint compatibility. No PCB layout changes are required for mechanical substitution.

Q: Are the coil electrical characteristics identical between these parts?

A: Yes. Coil voltage (9VDC), coil current (11.1 mA), and coil resistance (810 Ohms) are identical. The must-operate voltage threshold of 6.75 VDC is also equivalent, ensuring compatible drive circuit requirements.

Q: What is the significance of the timing differences (operate and release times)?

A: The substitute part exhibits operate time of 3 ms (vs. 2 ms original) and release time of 3 ms (vs. 1 ms original). Applications requiring faster switching response must evaluate whether these timing differences impact system performance. Circuit-level timing analysis is necessary for time-critical applications.

Q: Does the substitute part meet the same regulatory compliance standards?

A: Yes. The 6-1462037-4 is RoHS3 compliant and REACH unaffected, matching the compliance profile of the EE2-9SNU-L.

Q: What is the advantage of the hermetic sealing on the substitute part?

A: Hermetic sealing provides enhanced protection against moisture ingress and environmental contamination. This is beneficial for applications in humid, corrosive, or sealed enclosure environments. The original EE2-9SNU-L specification does not indicate sealed construction.

Q: Is the contact material difference significant?

A: The original uses silver alloy and gold alloy contacts, while the substitute uses palladium, ruthenium, and gold. Both material systems are suitable for 2A switching at 250VAC/220VDC. Material selection differences reflect manufacturer design choices and do not indicate incompatibility for standard relay applications.

Q: What is the MSL (Moisture Sensitivity Level) difference between these parts?

A: The original part has MSL 1 (unlimited shelf life), while the substitute has MSL 3 (168-hour maximum floor life after moisture exposure). For high-volume production or extended storage, the substitute requires stricter moisture control during handling and storage.

Q: Is the substitute part available in the same packaging format?

A: The substitute is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Confirm packaging compatibility with your assembly equipment and procurement requirements.
