Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1617569-4 are qualified based on matching the following critical parameters:

• Contact form configuration (DPDT / 2 Form C)
• Coil voltage rating (6VDC)
• Contact current rating (1 A)
• Maximum switching voltage (115VAC, 28VDC)
• Coil current draw (30 mA)
• Coil type (Non Latching)
• Mounting method (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-65°C ~ 125°C)
• Hermetic seal rating
• Contact material composition (Silver Palladium and Gold)
• Coil resistance (200 Ohms)

All substitute parts listed maintain these electrical and mechanical parameters, ensuring direct functional equivalence in circuit applications. Differences in series designation (MS, MST, MGA) and base product numbers reflect internal TE Connectivity product line variations that do not affect performance or interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1617569-4, 6-1617543-5, and 8-1617542-7—are active production items from TE Connectivity Aerospace, Defense and Marine and maintain identical electrical and mechanical specifications for DPDT relay applications.

Compliance Considerations:

The 1617569-4 (main part) carries RoHS non-compliant status. The substitute part 6-1617543-5 maintains RoHS non-compliant status with REACH Unaffected certification. The substitute part 8-1617542-7 is ROHS3 Compliant with REACH Unaffected certification, making it suitable for applications requiring RoHS3 compliance.

Inventory Availability:

• 1617569-4: 640 units in stock
• 6-1617543-5: 956 units in stock
• 8-1617542-7: 987 units in stock

Selection between these parts should be based on compliance requirements, inventory availability, and series preference. All parts are functionally interchangeable in circuit applications requiring DPDT 6VDC general purpose relay switching.

Frequently Asked Questions (FAQ)

Q: Can the 6-1617543-5 be used as a direct replacement for the 1617569-4?

A: Yes. The 6-1617543-5 maintains all critical electrical and mechanical parameters including coil voltage, contact rating, switching voltage, operating temperature range, and termination style. The difference in series designation (MST versus MS) does not affect functional compatibility.

Q: What is the primary difference between the 8-1617542-7 and the other two parts?

A: The 8-1617542-7 is ROHS3 Compliant, whereas the 1617569-4 and 6-1617543-5 are RoHS non-compliant. All three parts are electrically and mechanically identical. Selection of the 8-1617542-7 is required for applications subject to RoHS3 regulatory requirements.
