Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6-1393222-4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Contact Form: SPST-NO (1 Form A)
• Coil Voltage: 60VDC
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Seal Rating: Sealed - Fully
• Coil Resistance: 15.27 kOhms
• Must Operate Voltage: 40.8 VDC
• Operate Time: 10 ms
• Release Time: 5 ms

Allowable Variation Parameters:

• Contact Rating (Current): Substitute must equal or exceed 8A
• Switching Voltage: Substitute must equal or exceed 400VAC
• Coil Insulation Class: Substitute may differ (Class A to Class F represents improved thermal performance)
• Must Release Voltage: Substitute may differ within sealed relay specifications
• Product Status: Active status preferred for ongoing availability

The substitute part 6-1416200-1 meets all mandatory matching parameters while providing enhanced current rating (10A versus 8A) and improved coil insulation (Class F versus Class A), with active product status ensuring continued supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 6-1416200-1 is suitable for direct replacement of the obsolete 6-1393222-4 based on the following engineering criteria:

Functional Equivalence: Both relays maintain identical contact form (SPST-NO), coil voltage (60VDC), coil resistance (15.27 kOhms), and switching timing characteristics (10 ms operate, 5 ms release). Mechanical compatibility is assured through matching mounting type (through hole) and termination style (PC pin).

Enhanced Specifications: The substitute provides increased contact current rating (10A versus 8A), maintaining the 400VAC maximum switching voltage. The improved coil insulation class (Class F versus Class A) provides superior thermal performance without affecting electrical operation.

Compliance and Availability: The substitute part carries active product status with ROHS3 compliance certification, ensuring long-term supply chain availability and regulatory alignment for new production. The main part's obsolete status necessitates transition to the active equivalent.

Operational Compatibility: The substitute's must operate voltage (40.8 VDC) and operate/release timing remain identical to the main part, ensuring drop-in compatibility in existing circuit designs. The increased must release voltage (6 VDC versus 0.6 VDC) represents a minor operational difference within sealed relay specifications that does not affect standard switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 6-1416200-1 directly replace the 6-1393222-4 in existing designs?

A: Yes. Both relays share identical contact form, coil voltage, coil resistance, mounting type, termination style, and switching timing. The substitute's higher current rating (10A) and improved coil insulation (Class F) provide enhanced performance without requiring circuit modification.

Q: What is the significance of the higher contact current rating on the substitute part?

A: The 6-1416200-1 is rated for 10A continuous current versus 8A on the main part. This provides additional design margin and allows the relay to handle higher switching loads. Applications requiring only 8A operation remain fully compatible.

Q: How does the Class F coil insulation on the substitute differ from Class A on the main part?

A: Class F insulation provides higher thermal performance and temperature stability compared to Class A. This represents an improvement that does not affect electrical compatibility or circuit operation.

Q: Why is the must release voltage different between the two parts?

A: The must release voltage (0.6 VDC on the main part versus 6 VDC on the substitute) reflects design variations within sealed relay specifications. Both values remain well within normal operating margins for standard switching applications and do not affect functional compatibility.

Q: What is the impact of the substitute's specified operating temperature range?

A: The substitute specifies -40°C to 85°C operating range, whereas the main part does not provide this specification. This documented range on the substitute provides additional design confidence for temperature-sensitive applications.

Q: Does the substitute's ROHS3 compliance affect compatibility?

A: No. ROHS3 compliance indicates the substitute meets environmental and regulatory standards for new production. This certification supports long-term supply availability and regulatory alignment without affecting electrical or mechanical compatibility.

Q: Are there packaging differences between the main part and substitute?

A: The main part packaging is not specified, while the substitute is supplied in tube packaging. Tube packaging is standard for through-hole relays and does not affect component functionality or circuit integration.

Q: Can the substitute be used in applications originally designed for the main part?

A: Yes. The substitute meets all mandatory electrical and mechanical parameters for direct replacement. The enhanced specifications (higher current rating, improved insulation class, active product status) make it suitable for both legacy applications and new designs.
