Parameter Comparison

Engineering Selection Recommendations

All four parts—1-1617031-6, 2-1617031-8, 3-1617533-0, and 4-1617033-5—are functionally equivalent general purpose relays within the TE Connectivity HFW and CII series. Selection between these parts is determined by application requirements and regulatory compliance constraints rather than electrical or mechanical performance differences.

Primary Selection Criteria:

Regulatory Compliance: The 1-1617031-6 carries "Not applicable" RoHS status with "Vendor Undefined" REACH status. The substitute parts 2-1617031-8, 3-1617533-0, and 4-1617033-5 are designated as "RoHS non-compliant" with "REACH Unaffected" status. Applications subject to RoHS or REACH regulations must account for these compliance designations during component selection.

Packaging Configuration: The 1-1617031-6 is supplied with unspecified packaging ("-"), while all substitute parts are supplied in Bulk packaging. Packaging selection depends on procurement and assembly workflow requirements.

Inventory Availability: Part 3-1617533-0 offers the highest inventory level at 1097 pieces, followed by 1-1617031-6 at 846 pieces, 4-1617033-5 at 822 pieces, and 2-1617031-8 at 804 pieces. Inventory considerations may influence selection for high-volume production schedules.

Base Product Number Variation: The 1-1617031-6 and 2-1617031-8 share base product number 1617031, while 3-1617533-0 uses base product number 1617533 and 4-1617033-5 uses base product number 1617033. These variations reflect internal TE Connectivity product line designations but do not affect functional equivalence.

All parts maintain identical electrical performance, thermal operating range, switching characteristics, and hermetic sealing specifications required for aerospace, defense, and marine applications.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts 2-1617031-8, 3-1617533-0, and 4-1617033-5 be used interchangeably with the 1-1617031-6 in circuit applications?

A: Yes. All four parts maintain identical electrical and mechanical specifications including coil voltage (26.5VDC), contact form (DPDT), current rating (2A), switching voltage (115VAC, 28VDC - Max), coil current (37.9 mA), operating temperature range (-65°C ~ 125°C), and hermetic sealing. Direct functional substitution is supported without circuit redesign.

Q: What is the difference between the 1-1617031-6 and its substitutes?

A: The primary differences are packaging configuration and regulatory compliance status. The 1-1617031-6 has unspecified packaging and "Not applicable" RoHS status. The substitute parts are supplied in Bulk packaging and carry "RoHS non-compliant" designation. All electrical and mechanical performance parameters are identical.

Q: Are there any timing or performance differences between these relay models?

A: No. All four parts specify identical operate time (4 ms), release time (4 ms), must operate voltage (13.5 VDC), and must release voltage (1.5 VDC). Switching performance and response characteristics are equivalent across all models.

Q: Which substitute part should be selected for RoHS-compliant applications?

A: None of the identified substitutes provide RoHS compliance. The 1-1617031-6 carries "Not applicable" RoHS status, while substitutes 2-1617031-8, 3-1617533-0, and 4-1617033-5 are designated "RoHS non-compliant." Applications requiring RoHS compliance must evaluate alternative relay models outside this equivalence group.

Q: Do all parts have the same contact material composition?

A: Yes. All four parts use Silver (Ag) and Gold (Au) contact materials, ensuring consistent electrical conductivity and contact reliability across substitutions.

Q: What is the significance of the different base product numbers (1617031, 1617533, 1617033)?

A: Base product numbers reflect TE Connectivity internal product line designations. The 1-1617031-6 and 2-1617031-8 share base product number 1617031, while 3-1617533-0 and 4-1617033-5 use different base numbers. These designations do not affect functional equivalence or performance characteristics.

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

A: Yes. All four parts are manufactured by TE Connectivity Aerospace, Defense and Marine with active product status. The hermetic sealing, extended temperature range (-65°C ~ 125°C), and specified electrical characteristics support deployment in aerospace, defense, and marine environments.

Q: What is the coil resistance specification, and is it identical across all parts?

A: All four parts specify 700 Ohms coil resistance. This parameter is critical for drive circuit design and is maintained uniformly across the 1-1617031-6 and all substitute parts.

Q: Can these relays be used in applications requiring REACH compliance?

A: The 1-1617031-6 carries "Vendor Undefined" REACH status. The substitute parts 2-1617031-8, 3-1617533-0, and 4-1617033-5 are designated "REACH Unaffected." Applications subject to REACH regulations should clarify compliance requirements with the component supplier.
