Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3-1393223-2 relay is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Contact form configuration (SPDT / 1 Form C)
• Coil voltage (24VDC)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-40°C ~ 85°C)
• Must operate and release voltage thresholds (16.3 VDC / 2.4 VDC)
• Switching voltage capability (400VAC - Max)

Secondary Compatibility Parameters:

• Contact current rating (8A minimum)
• Coil resistance (2.27 kOhms nominal)
• Operate and release timing (10 ms / 5 ms)
• Relay type classification (General Purpose)
• Series designation (MSR, SCHRACK)

Substitute parts must maintain all primary criteria. Variations in contact material composition, coil insulation class, seal rating specification, and product status (active vs. obsolete) do not preclude substitution when all primary parameters align.

Engineering Selection Recommendations

V23061B1007A501 (Recommended Primary Substitute)

The V23061B1007A501 provides full parametric equivalence to the 3-1393223-2 across all critical electrical and mechanical specifications. This part maintains identical contact rating (8A), coil voltage (24VDC), contact material (Silver Nickel), coil resistance (2.27 kOhms), and timing characteristics. The part carries active product status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment. Packaging is supplied in tube format.

V23061B1007A301 (Secondary Substitute)

The V23061B1007A301 maintains full parametric equivalence across all primary substitution criteria. Contact material differs (Silver Tin Oxide vs. Silver Nickel), which does not affect functional compatibility for general purpose relay applications. This part carries active product status with RoHS compliance certification. Packaging is supplied in tube format.

6-1416200-7 (Higher Current Rating Substitute)

The 6-1416200-7 provides functional substitution with elevated contact current rating (10A vs. 8A). All other critical parameters remain equivalent, including coil voltage, mounting type, termination style, and timing specifications. Coil insulation class differs (Class F vs. Class A) and seal rating specification differs (Sealed - Flux Protection vs. Sealed - Fully). This part carries active product status with ROHS3 compliance and REACH unaffected certification. Selection of this part is appropriate for applications requiring higher contact current capacity within the same form factor and coil voltage specification.

Frequently Asked Questions (FAQ)

Q: Can the V23061B1007A501 directly replace the 3-1393223-2 in existing circuit designs?

A: Yes. The V23061B1007A501 maintains identical electrical specifications including coil voltage (24VDC), contact form (SPDT), contact rating (8A), coil resistance (2.27 kOhms), and timing parameters (10 ms operate, 5 ms release). Physical mounting (Through Hole) and termination style (PC Pin) are identical. No circuit modifications are required.

Q: What is the difference between the contact materials used in these relays?

A: The 3-1393223-2 and V23061B1007A501 use Silver Nickel (AgNi) contact material. The V23061B1007A301 uses Silver Tin Oxide (AgSnO) contact material. Both materials are suitable for general purpose relay applications and do not affect functional compatibility in standard switching circuits.

Q: Why does the 6-1416200-7 have a higher current rating (10A vs. 8A)?

A: The 6-1416200-7 is rated for 10A contact current, compared to 8A for the main part. This represents an enhanced contact design within the same relay form factor and coil voltage specification. The higher rating does not preclude use in 8A applications; the part is backward compatible for lower current requirements.

Q: Are there packaging differences between these substitute parts?

A: The main part 3-1393223-2 is specified with packaging designation "-" (not specified). All three substitute parts are supplied in tube packaging format. Tube packaging is standard for through-hole relay components and does not affect electrical or mechanical compatibility.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 3-1393223-2 carries obsolete product status, indicating discontinued manufacturing. The three substitute parts (V23061B1007A501, V23061B1007A301, and 6-1416200-7) all carry active product status, ensuring continued availability for procurement and long-term supply chain reliability.

Q: Do all substitute parts meet current regulatory compliance standards?

A: The V23061B1007A501 and 6-1416200-7 are ROHS3 compliant with REACH unaffected status. The V23061B1007A301 is RoHS compliant. All three parts carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications support use in regulated manufacturing environments.

Q: Can the 6-1416200-7 be used in applications designed for 8A operation?

A: Yes. The 6-1416200-7 is rated for 10A contact current, which exceeds the 8A requirement of the original design. The part operates within all specified voltage, timing, and temperature parameters. Use in 8A applications represents operation within the part's rated capability.

Q: What are the coil resistance specifications across these parts?

A: The 3-1393223-2, V23061B1007A501, and V23061B1007A301 all specify 2.27 kOhms coil resistance. The 6-1416200-7 specifies 2270 Ohms, which is numerically equivalent (2.27 kOhms). Coil resistance equivalence ensures identical coil current draw (10.6 mA for specified parts) and circuit behavior.
