Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-1617534-8 are identified based on electrical and mechanical parameter equivalence within the HFW and CII series families from TE Connectivity Aerospace, Defense and Marine. All substitute parts maintain identical specifications across the following critical parameters:

• Contact form configuration (DPDT / 2 Form C)
• Contact current rating (2 A)
• Coil voltage (26.5VDC)
• Coil current (37.9 mA)
• Coil resistance (700 Ohms)
• Switching voltage capability (115VAC, 28VDC - Max)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Seal rating (Sealed - Hermetically)
• Operating temperature range (-65°C ~ 125°C)
• Contact material composition (Silver and Gold)
• Switching timing (4 ms operate, 4 ms release)
• Voltage thresholds (13.5 VDC must operate, 1.5 VDC must release)

The substitute parts differ only in base product number designation, which reflects internal TE Connectivity product line variations within the same functional and performance class.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—2-1617031-8, 3-1617533-0, and 4-1617033-5—are direct parametric equivalents to the 3-1617534-8 and are suitable for component substitution in applications requiring identical electrical and mechanical performance. Each substitute part maintains active product status from TE Connectivity Aerospace, Defense and Marine and carries identical compliance certifications including RoHS non-compliant status, REACH Unaffected designation, EAR99 export classification, and HTSUS code 8536.41.0050.

Selection among these equivalent parts may be based on inventory availability, supply chain logistics, or internal design documentation requirements. All parts are manufactured to the same specifications and are interchangeable within the HFW and CII series relay families.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used interchangeably with the 3-1617534-8 in existing circuit designs?

A: Yes. The substitute parts 2-1617031-8, 3-1617533-0, and 4-1617033-5 are parametric equivalents with identical electrical and mechanical specifications. They share the same contact form, current rating, coil voltage, switching characteristics, mounting type, and termination style, making them directly interchangeable in applications designed for the 3-1617534-8.

Q: What are the critical parameters that define substitution eligibility for this relay?

A: Substitution eligibility is determined by equivalence in contact form (DPDT), contact current rating (2 A), coil voltage (26.5VDC), coil resistance (700 Ohms), switching voltage capability (115VAC, 28VDC - Max), mounting type (Through Hole), termination style (PC Pin), seal rating (Hermetically Sealed), operating temperature range (-65°C ~ 125°C), and switching timing (4 ms operate and release). All substitute parts maintain these parameters identically.

Q: Are there any compliance or certification differences between the main part and substitute parts?

A: No. All parts share identical compliance status: RoHS non-compliant, REACH Unaffected, EAR99 export classification, and HTSUS code 8536.41.0050. Regulatory and trade compliance considerations are equivalent across all parts.

Q: What is the difference between the part numbers if all electrical and mechanical specifications are identical?

A: The part numbers reflect internal TE Connectivity product line designations within the HFW and CII series families. The differences are administrative and do not affect functional performance, electrical characteristics, or mechanical compatibility.

Q: Are all substitute parts currently in active production?

A: Yes. All substitute parts—2-1617031-8, 3-1617533-0, and 4-1617033-5—maintain active product status with TE Connectivity Aerospace, Defense and Marine.

Q: Can these relays be used in aerospace, defense, and marine applications?

A: Yes. All parts are manufactured by TE Connectivity Aerospace, Defense and Marine and are designed for use in these application domains. The hermetically sealed construction, extended operating temperature range (-65°C ~ 125°C), and silver/gold contact materials support reliability requirements in these environments.
