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

Part Overview

The JMSCD-26XM 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 DPDT (2 Form C) contact configuration and 1A contact rating. The component is qualified to MIL-R-39016/16 military standards and features integrated diode protection with silver palladium and gold contact materials. The JMSCD-26XM maintains active product status with 710 units currently in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required for applications where the primary part is unavailable or when alternative compliance profiles are acceptable.

The JMSCD-26XP currently maintains higher inventory (905 units) compared to the JMSCD-26XM (710 units), both available as new original stock in bulk packaging.

Frequently Asked Questions (FAQ)

Q: Are the JMSCD-26XM and JMSCD-26XP electrically interchangeable?

A: Yes. Both parts operate at 26.5VDC coil voltage, feature DPDT (2 Form C) contact configuration with 1A rating, and share identical switching voltage (115VAC, 28VDC - Max), coil resistance (3300 Ohms), and timing specifications (4 ms operate, 7.5 ms release).

Q: What is the difference between these two relay models?

A: The primary differences are compliance-related. The JMSCD-26XM is ROHS3 compliant with REACH Unaffected status. The JMSCD-26XP is RoHS non-compliant with Vendor Undefined REACH status. All electrical and mechanical parameters are identical.

Q: Can I use JMSCD-26XP in an application requiring RoHS compliance?

A: No. The JMSCD-26XP is RoHS non-compliant. Applications with RoHS compliance requirements must use the JMSCD-26XM.

Q: Are the through-hole mounting and PC pin termination identical between both parts?

A: Yes. Both relays feature identical through-hole mounting type and PC pin termination style, ensuring mechanical compatibility in circuit board layouts.

Q: Do both relays operate across the same temperature range?

A: Yes. Both the JMSCD-26XM and JMSCD-26XP operate across the identical temperature range of -65°C to 125°C.

Q: What is the contact material composition for both relays?

A: Both relays use Silver Palladium (AgPd) and Gold (Au) contact materials, providing identical electrical and wear characteristics.

Q: Are both relays hermetically sealed?

A: Yes. Both the JMSCD-26XM and JMSCD-26XP feature hermetically sealed construction with identical seal rating.

Q: What military qualification applies to both parts?

A: Both relays are qualified to MIL-R-39016/16 military standards, indicating equivalent military-grade performance and reliability.

Q: Is there a difference in coil insulation between these parts?

A: No coil insulation specification is provided for either part in the available technical data.

Q: Which part should I select if both are available?

A: Selection depends on application requirements. For RoHS-compliant applications, use JMSCD-26XM. For applications without RoHS requirements, either part is electrically and mechanically equivalent. The JMSCD-26XP currently has higher inventory availability.
