Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1617343-5 relay is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for a part to function as a direct substitute:

Mandatory Equivalence Parameters:

• Contact Form: DPDT (2 Form C)
• Contact Rating: 2 A
• Coil Voltage: 12VDC
• Switching Voltage: 115VAC, 28VDC - Max
• Coil Current: 75 mA
• Coil Resistance: 160 Ohms
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Seal Rating: Sealed - Hermetically
• Operating Temperature Range: -65°C ~ 125°C
• Contact Material: Silver (Ag), Gold (Au)
• Coil Type: Non Latching
• Operate/Release Time: 4 ms each
• Must Operate/Release Voltages: 6.4 VDC / 0.7 VDC

All identified substitute parts maintain these parameters within the HFW and CII relay series manufactured by TE Connectivity Aerospace, Defense and Marine.

Parameter Comparison

Engineering Selection Recommendations

All four relay part numbers (1617343-5, 2-1617033-6, 3-1617030-3, and 4-1617535-1) are active products manufactured by TE Connectivity Aerospace, Defense and Marine and maintain identical electrical and mechanical specifications for DPDT general purpose relay applications.

Compliance Considerations:

Part 1617343-5 and 4-1617535-1 are designated RoHS non-compliant with REACH Unaffected status. Part 2-1617033-6 carries RoHS non-compliant status with REACH Unaffected designation. Part 3-1617030-3 has RoHS status listed as Not Applicable with Vendor Undefined REACH status.

All parts carry ECCN classification EAR99 and HTSUS code 8536.41.0050, indicating consistent regulatory treatment for aerospace, defense, and marine applications.

Packaging and Inventory:

Part 1617343-5 is supplied in Bulk packaging with 1,058 units in stock. Part 2-1617033-6 is supplied in Bulk packaging with 760 units available. Part 3-1617030-3 has packaging listed as unspecified with 758 units in stock. Part 4-1617535-1 is supplied in Bulk packaging with 668 units available.

Selection between these equivalent parts is determined by packaging requirements, inventory availability, and compliance documentation needs for specific applications.

Frequently Asked Questions (FAQ)

Q: Can part 2-1617033-6 be used as a direct replacement for 1617343-5?

A: Yes. Part 2-1617033-6 maintains identical electrical parameters including 12VDC coil voltage, 2A contact rating, DPDT configuration, 160 Ohm coil resistance, and hermetically sealed construction. Both parts operate within -65°C to 125°C temperature range with 4 ms switching times. The parts differ only in manufacturing variant designation within the HFW/CII series.

Q: What is the difference between 3-1617030-3 and the other substitute parts?

A: Part 3-1617030-3 maintains all critical electrical and mechanical parameters identical to 1617343-5. The primary difference is packaging designation, which is listed as unspecified rather than Bulk. All switching characteristics, coil specifications, contact ratings, and operating conditions remain equivalent.

Q: Are all substitute parts suitable for aerospace and defense applications?

A: All four parts are manufactured by TE Connectivity Aerospace, Defense and Marine and carry identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications. Compliance documentation requirements should be verified against specific application and customer specifications.

Q: What is the significance of the MSL (Moisture Sensitivity Level) differences?

A: Part 1617343-5 lists MSL as Not Applicable. Parts 2-1617033-6, 3-1617030-3, and 4-1617535-1 list MSL as 1 (Unlimited). This indicates different moisture sensitivity classifications; however, all parts maintain hermetically sealed construction, which provides protection independent of MSL designation.

Q: Can these relays be used interchangeably in existing circuit board designs?

A: Yes. All substitute parts use identical Through Hole mounting with PC Pin termination style. The physical footprint and electrical interface remain constant across all four part numbers, enabling direct substitution in existing PCB layouts without design modification.

Q: What coil current should be supplied to operate these relays?

A: All parts require 75 mA coil current at 12VDC nominal. The coil resistance of 160 Ohms is consistent across all variants. Must Operate Voltage is 6.4 VDC minimum, and Must Release Voltage is 0.7 VDC maximum.

Q: Are there any switching voltage limitations for these relays?

A: All parts are rated for maximum switching voltage of 115VAC or 28VDC. Contact rating is 2A across both AC and DC switching applications. Specific application voltage selection should be based on load requirements and circuit design parameters.
