JMACD-18XP General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The JMACD-18XP is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This DPDT (2 Form C) through-hole relay operates at 18VDC coil voltage with a 1A contact rating and is designed for applications requiring hermetically sealed switching functionality. The part is currently active in production with 784 pieces available in inventory. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JMACD-18XP are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Coil voltage: 18VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 1 A
• Switching voltage: 115VAC, 28VDC - Max
• Coil current: 20.5 mA
• Mounting type: Through Hole
• Seal rating: Sealed - Hermetically
• Operating temperature range: -65°C ~ 125°C
• Coil resistance: 880 Ohms
• Must operate voltage: 10.5 VDC
• Must release voltage: 0.91 VDC
• Operate time: 2 ms
• Release time: 4 ms
• Termination style: PC Pin
• Contact material: Silver Palladium (AgPd), Gold (Au)

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison
