Electrical Compatibility Requirements:

• Coil voltage: 5VDC
• Coil current: 44.6 mA
• Coil resistance: 112 Ohms
• Contact form: SPST-NC (1 Form B)
• Contact rating: 8 A minimum
• Switching voltage: 400VAC maximum
• Must operate voltage: 3.5 VDC
• Must release voltage: 0.5 VDC

Mechanical Compatibility Requirements:

• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -40°C ~ 70°C minimum
• Coil type: Non Latching

Functional Equivalence:

• Relay type: General Purpose
• Seal rating: Sealed - Fully
• Operate time: 9 ms
• Release time: 5 ms

The substitute part 2-1393224-6 meets all electrical and mechanical compatibility requirements. The primary distinction is product status: 2-1393224-6 is Active, whereas 2-1393224-3 is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 2-1393224-6 is the direct substitute for the obsolete 2-1393224-3. Both parts are manufactured by TE Connectivity Potter & Brumfield Relays within the RY/SCHRACK series and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The 2-1393224-3 is classified as Obsolete, while the 2-1393224-6 is Active. For new designs and ongoing production, the 2-1393224-6 is the appropriate selection to ensure long-term component availability and supply chain continuity.

Compliance Status: The 2-1393224-6 carries ROHS3 compliance and REACH Unaffected status, providing regulatory alignment for applications subject to these requirements. The 2-1393224-3 does not specify these compliance certifications.

Contact Material Difference: The 2-1393224-3 uses Silver Cadmium Oxide (AgCdO) contact material, while the 2-1393224-6 uses Silver Nickel (AgNi). Both materials are suitable for general-purpose relay applications with 8A contact rating and 400VAC maximum switching voltage. The contact material difference does not affect functional equivalence for standard switching applications.

Moisture Sensitivity: The 2-1393224-6 is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The 2-1393224-3 is rated Not Applicable. This difference does not impact substitution suitability.

Frequently Asked Questions (FAQ)

Q: Can the 2-1393224-6 directly replace the 2-1393224-3 in existing designs?

A: Yes. The 2-1393224-6 is electrically and mechanically equivalent to the 2-1393224-3. All critical parameters including coil voltage, contact form, contact rating, switching voltage, coil current, coil resistance, mounting type, and termination style are identical. Direct substitution is supported without circuit modification.

Q: What is the significance of the contact material difference between AgCdO and AgNi?

A: Both Silver Cadmium Oxide (AgCdO) and Silver Nickel (AgNi) are established contact materials for general-purpose relays rated at 8A and 400VAC maximum switching voltage. The contact material difference does not affect functional performance or compatibility in standard switching applications. The 2-1393224-6 with AgNi contacts is suitable for all applications previously served by the 2-1393224-3 with AgCdO contacts.

Q: Why is the 2-1393224-3 listed as Obsolete?

A: The 2-1393224-3 carries an Obsolete product status, indicating it is no longer in active production. The 2-1393224-6 is the Active equivalent part maintained in current production by TE Connectivity Potter & Brumfield Relays.

Q: Are there packaging differences between these parts?

A: The 2-1393224-3 packaging is listed as unspecified in the provided data. The 2-1393224-6 is supplied in Bulk packaging. Both parts use identical PC Pin termination for through-hole mounting on printed circuit boards.

Q: Does the 2-1393224-6 meet regulatory requirements for new designs?

A: The 2-1393224-6 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in most jurisdictions. The 2-1393224-3 does not specify these compliance certifications. For applications subject to ROHS or REACH regulations, the 2-1393224-6 is the appropriate selection.

Q: What is the operating temperature range for both parts?

A: Both the 2-1393224-3 and 2-1393224-6 operate across the temperature range of -40°C to 70°C. This range is identical for both parts and supports substitution in temperature-controlled and industrial environments within these limits.

Q: Are the coil electrical characteristics identical?

A: Yes. Both parts have identical coil specifications: 5VDC coil voltage, 44.6 mA coil current, 112 Ohms coil resistance, 3.5 VDC must operate voltage, and 0.5 VDC must release voltage. Switching timing is also identical: 9 ms operate time and 5 ms release time.
