Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 8-1617351-3 are qualified based on electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters: 6VDC coil voltage, DPDT contact configuration, 1A contact rating, 115VAC/28VDC maximum switching voltage, 30mA coil current, non-latching coil type, through-hole mounting, hermetic seal rating, -65°C to 125°C operating temperature range, Silver Palladium and Gold contact materials, 200 Ohm coil resistance, PC pin termination, and integrated diode feature.

The substitute parts differ only in series designation (MST/MGA versus MS) and base product number, reflecting internal TE Connectivity product line variations. These differences do not affect functional performance or electrical characteristics in applications requiring the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products from TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Selection between these parts is based on compliance requirements and product status:

8-1617351-3 (Main Part): RoHS non-compliant. Select this part for applications where RoHS compliance is not required or where legacy system compatibility is necessary.

6-1617543-5 (Substitute): RoHS non-compliant. Functionally equivalent to the main part with identical electrical performance. Suitable for applications with the same compliance requirements as the main part.

8-1617542-7 (Substitute): RoHS3 compliant. Select this part for applications requiring RoHS compliance or for new designs where regulatory compliance is mandatory. This part provides the same electrical and mechanical functionality as the main part while meeting current environmental regulations.

All parts are REACH unaffected and classified under ECCN EAR99. Inventory availability is confirmed for all three parts, with 1145 units of the main part, 956 units of 6-1617543-5, and 987 units of 8-1617542-7 currently in stock.

Frequently Asked Questions (FAQ)

Q: Can I substitute 6-1617543-5 or 8-1617542-7 for 8-1617351-3 in my circuit?

A: Yes. Both substitute parts maintain identical electrical specifications including 6VDC coil voltage, DPDT contact configuration, 1A contact rating, 30mA coil current, 200 Ohm coil resistance, and all timing parameters. The parts are functionally interchangeable from an electrical standpoint.

Q: What is the difference between these three part numbers?

A: The parts differ in series designation (MS versus MST versus MGA) and RoHS compliance status. The main part (8-1617351-3) and 6-1617543-5 are RoHS non-compliant, while 8-1617542-7 is RoHS3 compliant. All other electrical and mechanical parameters are identical.

Q: Which part should I use for a new design?

A: If RoHS compliance is required, use 8-1617542-7. If RoHS compliance is not a requirement, any of the three parts are suitable. Verify your application's regulatory requirements before final selection.

Q: Are the through-hole mounting dimensions identical across all three parts?

A: All three parts share identical mounting type (through-hole) and termination style (PC pin). Consult the detailed mechanical drawings for each part number to confirm specific pin spacing and package dimensions for your PCB layout.

Q: What is the operating temperature range for these relays?

A: All three parts operate across the identical temperature range of -65°C to 125°C, making them suitable for aerospace, defense, and marine applications requiring extended temperature performance.

Q: Are these parts hermetically sealed?

A: Yes. All three parts feature hermetic sealing, providing protection against moisture and environmental contamination. This is critical for aerospace and marine applications.

Q: What contact materials are used in these relays?

A: All three parts use Silver Palladium (AgPd) and Gold (Au) contact materials, providing reliable switching performance and corrosion resistance across the specified switching voltage range of 115VAC and 28VDC maximum.

Q: Can I use these relays for switching AC or DC loads?

A: Yes. All three parts are rated for switching both 115VAC and 28VDC loads at the maximum switching voltage specification. The 1A contact rating applies to both AC and DC switching applications.
