Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8-1393222-3 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Coil voltage: 6VDC
• Contact form: SPDT (1 Form C)
• Mounting type: Through hole
• Termination style: PC pin
• Coil type: Non latching
• Operating temperature range: -40°C ~ 85°C
• Must operate voltage: 4.1 VDC
• Must release voltage: 0.6 VDC
• Coil resistance: 165 Ohms

Secondary Compatibility Parameters:

• Contact rating current: 8A minimum
• Switching voltage: 400VAC maximum
• Seal rating: Sealed construction
• Operate and release times: 10 ms and 5 ms respectively

The substitute parts listed maintain full electrical and mechanical compatibility with the original 8-1393222-3 specification. Variations in contact material composition and seal protection type do not affect functional substitution within the defined parameter set.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred):

The 3-1416200-8 provides the most direct substitution for the obsolete 8-1393222-3. Both components share identical electrical specifications, including coil voltage, contact form, current rating, and timing characteristics. The 3-1416200-8 maintains active product status with TE Connectivity, ensuring long-term availability and supply chain continuity. This part is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production environments.

For Enhanced Current Capacity:

The 6-1416200-4 offers a higher contact current rating of 10A compared to the 8A specification of the main part. This substitute operates within all other electrical parameters and maintains the same coil voltage, timing, and temperature range. The 6-1416200-4 features Class F coil insulation and sealed flux protection, providing enhanced thermal and environmental protection. This part is also RoHS3 compliant and REACH unaffected. Selection of this substitute is appropriate when applications require additional current margin or enhanced environmental sealing.

Both substitute parts are manufactured by TE Connectivity Potter & Brumfield Relays and carry identical export classification (EAR99) and tariff codes (8536.41.0020) as the original component.

Frequently Asked Questions (FAQ)

Q: Can the 3-1416200-8 be used as a direct replacement for the 8-1393222-3?

A: Yes. The 3-1416200-8 maintains full electrical and mechanical compatibility with the 8-1393222-3 across all critical parameters: 6VDC coil voltage, SPDT contact form, 8A current rating, through-hole mounting with PC pin termination, and identical timing specifications. The primary difference is product status; the 3-1416200-8 is active and currently manufactured.

Q: What is the difference between the 3-1416200-8 and 6-1416200-4?

A: The 6-1416200-4 has a higher contact current rating of 10A versus 8A for the 3-1416200-8. Additionally, the 6-1416200-4 features Class F coil insulation and sealed flux protection, compared to Class A insulation and full sealing on the 3-1416200-8. All other electrical parameters, including coil voltage, timing, and operating temperature range, are identical.

Q: Are there packaging differences between these substitute parts?

A: Yes. The 3-1416200-8 is supplied in tube packaging, while the 6-1416200-4 is supplied in bulk packaging. The 8-1393222-3 original part does not specify packaging format. Packaging selection should be based on procurement and assembly requirements.

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

A: Both substitute parts are RoHS3 compliant and REACH unaffected. The original 8-1393222-3 does not specify these compliance certifications. For applications requiring regulatory compliance documentation, the 3-1416200-8 or 6-1416200-4 are appropriate selections.

Q: Can I use the 6-1416200-4 in an application designed for the 8-1393222-3?

A: Yes. The 6-1416200-4 maintains all critical electrical parameters required for substitution, including coil voltage, contact form, timing, and operating temperature range. The higher current rating of 10A provides additional capacity beyond the 8A specification of the original part. The enhanced seal rating and Class F insulation offer improved performance in demanding environments.

Q: What is the coil resistance of these relays?

A: All three parts—8-1393222-3, 3-1416200-8, and 6-1416200-4—have a coil resistance of 165 Ohms. This parameter is critical for circuit design and remains constant across all substitutes.

Q: Are there differences in contact material between these parts?

A: Yes. The 8-1393222-3 uses Silver Cadmium Oxide (AgCdO) and Gold (Au) contact material. The 3-1416200-8 uses Silver Tin Oxide (AgSnO), and the 6-1416200-4 uses Silver Nickel (AgNi). These material variations do not affect functional substitution within the specified electrical parameters and switching voltage ratings.
