• Coil Voltage: 6VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating (Current): 1 A
• Switching Voltage: 115VAC, 28VDC - Max
• Coil Current: 30 mA
• Coil Type: Non Latching
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Seal Rating: Sealed - Hermetically
• Operating Temperature Range: -65°C ~ 125°C
• Contact Material: Silver Palladium (AgPd), Gold (Au)
• Coil Resistance: 200 Ohms
• Features: Diode

The substitute parts 6-1617543-5 and 8-1617542-7 meet all electrical and mechanical requirements for direct substitution. These parts differ only in series designation (MST and MGA respectively, versus MGS for the primary part) and compliance certifications, which do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three relay part numbers (PRMGSCD-6YW, 6-1617543-5, and 8-1617542-7) are active products from TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and inventory availability.

For applications requiring RoHS3 compliance, select either PRMGSCD-6YW (MGS series) or 8-1617542-7 (MGA series). The part 6-1617543-5 (MST series) is RoHS non-compliant and is suitable only for applications without RoHS requirements.

All three parts maintain REACH Unaffected status and EAR99 export classification. Inventory availability is 678 pieces for PRMGSCD-6YW, 956 pieces for 6-1617543-5, and 987 pieces for 8-1617542-7.

Frequently Asked Questions (FAQ)

Q: Can 6-1617543-5 be used as a direct replacement for PRMGSCD-6YW?

A: The 6-1617543-5 is electrically and mechanically equivalent to PRMGSCD-6YW. However, 6-1617543-5 is RoHS non-compliant, while PRMGSCD-6YW is ROHS3 compliant. Use 6-1617543-5 only in applications where RoHS compliance is not required.

Q: What is the difference between the MGS, MST, and MGA series relays?

A: These designations identify different series within the TE Connectivity general purpose relay product line. All three series share identical electrical and mechanical parameters for the 6VDC DPDT 1A configuration. Series differences do not affect functional performance or pin compatibility.

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

A: All three parts are manufactured by TE Connectivity Aerospace, Defense and Marine and carry EAR99 export classification. Selection for aerospace and defense applications must also consider RoHS compliance requirements. PRMGSCD-6YW and 8-1617542-7 are ROHS3 compliant; 6-1617543-5 is not.

Q: What are the critical electrical parameters that must match for substitution?

A: The following parameters must be identical: coil voltage (6VDC), contact form (DPDT), contact rating (1A), switching voltage (115VAC, 28VDC max), coil current (30mA), coil resistance (200 Ohms), and operating temperature range (-65°C to 125°C).

Q: Can these relays be used interchangeably on the same PCB?

A: Yes. All three parts use identical through-hole PC pin termination and have the same physical mounting requirements. No PCB layout modifications are required when substituting between PRMGSCD-6YW, 6-1617543-5, and 8-1617542-7.

Q: What is the significance of the hermetically sealed rating?

A: The hermetically sealed rating indicates the relay contacts are enclosed in a sealed chamber, providing protection against moisture and environmental contamination. This specification is identical across all three substitute parts.

Q: Are there any temperature or voltage derating considerations?

A: All three relays operate across the identical temperature range of -65°C to 125°C and support the same maximum switching voltage of 115VAC or 28VDC. No derating differences exist between the substitute parts.
