JMSP-26XP General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The JMSP-26XP is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This hermetically sealed, through-hole mounted relay operates at 26.5VDC with a 1A contact rating and DPDT (2 Form C) contact configuration. The component is qualified to MIL-R-39016/11 military specification and is currently active in production with 929 pieces in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the primary part is unavailable, inventory constraints exist, or alternative compliance certifications are acceptable for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the JMSP-26XP is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

• Coil voltage: 26.5VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 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 resistance: 3300 Ohms
• Must operate voltage: 14 VDC
• Must release voltage: 1.4 VDC
• Operate time: 4 ms
• Release time: 2 ms
• Contact material: Silver Palladium (AgPd), Gold (Au)
• Military grade classification
• MIL-R-39016/11 qualification

The JMSW-26XM meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the JMSP-26XP and JMSW-26XM are active military-grade general purpose relays with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and inventory availability.

The JMSP-26XP is ROHS3 compliant, making it suitable for applications subject to RoHS (Restriction of Hazardous Substances) regulations. The JMSW-26XM is RoHS non-compliant and is appropriate for applications where RoHS compliance is not required.

Both parts carry MIL-R-39016/11 qualification and are manufactured by TE Connectivity Aerospace, Defense and Marine. Both are classified as EAR99 for export control purposes. The JMSP-26XP has higher current inventory availability at 929 pieces compared to 738 pieces for the JMSW-26XM.
