JMACT-26XM General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The JMACT-26XM is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This DPDT (2 Form C) relay is designed for through-hole mounting applications requiring 26.5VDC coil voltage with 1A contact rating. The component is actively produced and maintains military-grade qualification under MIL-R-28776/1. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or component availability across production cycles.

• Must operate voltage: 14.2 VDC
• Must release voltage: 1.37 VDC

Mechanical Parameters:

• Mounting type: Through Hole
• Termination style: PC Pin
• Seal rating: Sealed - Hermetically

Performance Parameters:

• Operate time: 2 ms
• Release time: 7.5 ms
• Operating temperature: -65°C ~ 125°C

Compliance Parameters:

• Grade: Military

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both the JMACT-26XM and JMACT-26XP are active production components manufactured by TE Connectivity Aerospace, Defense and Marine with identical military-grade qualification under MIL-R-28776/1. All electrical, mechanical, and performance parameters are equivalent across both part numbers. Selection between these components is based on inventory availability and procurement lead times rather than technical performance differences. Both components maintain the same compliance status (RoHS non-compliant, REACH Unaffected, EAR99 classification) and are suitable for aerospace, defense, and marine applications requiring hermetically sealed DPDT relays with 26.5VDC coil voltage and 1A contact rating.

Frequently Asked Questions (FAQ)

Q: Can JMACT-26XP be used as a direct replacement for JMACT-26XM in existing designs?
