Substitute Part Grouping Explanation

Substitution of the TE Connectivity 6-1617351-8 is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitutes:

Critical Matching Parameters:

• Coil voltage: 18 VDC
• Contact form: DPDT (2 Form C)
• Contact current rating: 1 A
• Switching voltage capability: 115 VAC, 28 VDC - Max
• Mounting type: Through Hole
• Seal rating: Sealed - Hermetically
• Operating temperature range: -65°C to 125°C
• Termination style: PC Pin
• Coil resistance: 1.6 kOhms
• Coil current: 11.3 mA
• Must operate voltage: 9.8 VDC
• Must release voltage: 0.92 VDC
• Operate time: 4 ms
• Release time: 2 ms

The substitute part PRMGSC-18XW meets all critical electrical and mechanical parameters, differing only in series designation (MGS vs. MS) and base product number, which do not affect functional equivalence in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the 6-1617351-8 and PRMGSC-18XW are active production components from TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Primary Selection Criteria:

• Both parts maintain identical compliance status: RoHS non-compliant, REACH Unaffected, and EAR99 export classification
• Both parts carry MSL Level 1 (Unlimited) moisture sensitivity rating
• Both parts are hermetically sealed with identical operating temperature ranges and switching characteristics

Inventory Availability:

• 6-1617351-8 (MS Series): 1174 units in stock
• PRMGSC-18XW (MGS Series): 903 units in stock

Application Considerations: The series designation difference (MS vs. MGS) and base product number variation reflect internal TE Connectivity product line organization and do not affect functional performance within the specified electrical and mechanical envelope. Either part is suitable for applications requiring 18 VDC coil voltage, 1 A DPDT switching, and hermetically sealed operation across the -65°C to 125°C temperature range.
