JMSC-26XPS General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The JMSC-26XPS is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This hermetically sealed, through-hole mounted relay features a DPDT (2 Form C) contact configuration with a 26.5VDC coil voltage and 1A contact rating. The component is qualified to MIL-R-39016/11 military specification and operates across an extended temperature range of -65°C to 125°C. The JMSC-26XPS maintains active product status with 768 units currently 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 JMSC-26XPS are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are established through the following key parameters:

Electrical Parameters: Coil voltage (26.5VDC), contact form (DPDT), contact rating (1A), switching voltage (115VAC, 28VDC - Max), coil resistance (3300 Ohms), must operate voltage (14 VDC), must release voltage (1.4 VDC), operate time (4 ms), and release time (2 ms).

Mechanical Parameters: Mounting type (Through Hole), termination style (PC Pin), seal rating (Sealed - Hermetically), and operating temperature range (-65°C ~ 125°C).

Compliance Parameters: Military grade classification, MIL-R-39016/11 qualification, contact material composition (Silver Palladium and Gold), and series designation (MS, CII).

Parts meeting all specified parameters within these categories are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the JMSC-26XPS and JMSW-26XM are active products manufactured by TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Both components are qualified to MIL-R-39016/11 military specification and maintain the same coil voltage, contact configuration, current rating, switching voltage, operating temperature range, and timing characteristics.

Selection between these parts is based on inventory availability and base product number designation. The JMSC-26XPS (base product JMSC-26) currently maintains 768 units in stock, while the JMSW-26XM (base product JMSW-26) maintains 738 units in stock. Both parts carry identical compliance status including RoHS non-compliance, REACH unaffected designation, and EAR99 export classification.

For applications requiring military-grade general purpose DPDT relays with 26.5VDC coil voltage and 1A contact rating in through-hole PC pin configuration, either part number satisfies the specified electrical and mechanical requirements.

Frequently Asked Questions (FAQ)

Q: Are JMSC-26XPS and JMSW-26XM direct substitutes?

A: Yes. Both parts are parametric equivalents with identical coil voltage (26.5VDC), contact form (DPDT), contact rating (1A), 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), and timing characteristics (4 ms operate, 2 ms release). Both are qualified to MIL-R-39016/11 and manufactured by the same supplier.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by coil voltage (26.5VDC), contact form (DPDT), contact rating (1A), switching voltage (115VAC, 28VDC - Max), coil resistance (3300 Ohms), must operate voltage (14 VDC), must release voltage (1.4 VDC), operate time (4 ms), and release time (2 ms).

Q: What are the key mechanical parameters that define substitution compatibility?

A: Substitution compatibility is determined by mounting type (Through Hole), termination style (PC Pin), seal rating (Sealed - Hermetically), and operating temperature range (-65°C ~ 125°C).

Q: Do both parts have the same contact material composition?

A: Yes. Both JMSC-26XPS and JMSW-26XM utilize Silver Palladium (AgPd) and Gold (Au) contact materials.

Q: Are there differences in compliance or regulatory status between these parts?

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH unaffected, EAR99 export classification, and MIL-R-39016/11 qualification.

Q: What is the difference between the JMSC-26 and JMSW-26 base product numbers?

A: The base product numbers identify different product lines within the TE Connectivity military relay series. JMSC-26XPS uses base product JMSC-26, while JMSW-26XM uses base product JMSW-26. Both are part of the MS and CII series designations and maintain identical electrical and mechanical specifications.

Q: Can these relays be used in applications requiring hermetic sealing?

A: Yes. Both parts are rated as Sealed - Hermetically, meeting hermetic sealing requirements for aerospace, defense, and marine applications.

Q: What is the moisture sensitivity level for these relays?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
