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

Part Overview

The JMACDG-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 switching applications up to 115VAC or 28VDC. The part is currently active in production with 1007 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the JMACDG-18XP are identified based on strict electrical and mechanical parameter equivalence. The following parameters must match identically for substitution eligibility:

• Coil Voltage: 18VDC
• Contact Form: DPDT (2 Form C)
• Contact Rating (Current): 1 A
• Switching Voltage: 115VAC, 28VDC - Max
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Seal Rating: Sealed - Hermetically
• Operating Temperature Range: -65°C ~ 125°C
• Coil Type: Non Latching
• Features: Diode

The JMACDG-18XL meets all substitution criteria and is classified as a parametric equivalent within the MAC series relay family.

Parameter Comparison

Engineering Selection Recommendations

Both JMACDG-18XP and JMACDG-18XL are active production parts from TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

Both parts share the same compliance profile: RoHS non-compliant, REACH Unaffected, and EAR99 export classification. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity restrictions for either part.

The JMACDG-18XP currently maintains higher inventory (1007 units) compared to the JMACDG-18XL (967 units). Either part is suitable for direct substitution in applications requiring a general purpose DPDT relay with 18VDC coil operation, 1A contact rating, and hermetically sealed construction.
