J1MSCT-26XM Equivalent & Substitute Parts

Part Overview

The J1MSCT-26XM is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This SPDT (Single Pole Double Throw) relay operates at 26.5VDC coil voltage with a 1A contact rating and is designed for through-hole mounting applications. The component is sealed hermetically and features a non-latching coil with integrated diode protection. Product status is Active, with 716 units currently in stock. Substitute parts are identified when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits equivalent component selection within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the J1MSCT-26XM is permissible with the J1MACT-26XPS based on electrical and mechanical parameter equivalence. Both components share identical specifications across all critical functional parameters: coil voltage (26.5VDC), contact form (SPDT), contact rating (1A), switching voltage (115VAC, 28VDC - Max), coil current (13.3 mA), non-latching coil type, through-hole mounting, PC pin termination, operating temperature range (-65°C ~ 125°C), hermetic seal rating, and coil resistance (2 kOhms). The substitute part maintains identical must-operate and must-release voltage thresholds, operate and release times, and contact material composition (Silver Palladium and Gold). Both components are manufactured by TE Connectivity Aerospace, Defense and Marine and carry identical compliance status (RoHS non-compliant, REACH Unaffected, EAR99 ECCN classification). The primary distinction is the series designation (1MS versus 1MA) and base product number (J1MSC versus J1MAC), which reflect internal product line organization without affecting functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the J1MSCT-26XM and J1MACT-26XPS are Active status products manufactured by TE Connectivity Aerospace, Defense and Marine. Selection between these components should be based on availability and inventory status. The J1MSCT-26XM currently maintains 716 units in stock, while the J1MACT-26XPS maintains 928 units in stock. Both components carry identical compliance certifications: RoHS non-compliant status, REACH Unaffected classification, and EAR99 ECCN designation. No electrical, mechanical, or environmental performance differential exists between these parts. Component selection may be determined by procurement lead times, supplier inventory levels, or design documentation requirements. Both parts are suitable for aerospace, defense, and marine applications requiring hermetically sealed SPDT relays with 26.5VDC coil operation and 1A contact rating.

Frequently Asked Questions (FAQ)

Q: Can J1MACT-26XPS be used as a direct replacement for J1MSCT-26XM in existing designs?

A: Yes. Both components share identical electrical specifications, mechanical dimensions (through-hole mounting with PC pin termination), operating temperature range, and switching characteristics. No circuit modifications or board layout changes are required.

Q: What is the difference between the 1MS and 1MA series designations?

A: The series designation reflects internal TE Connectivity product line organization. Both series meet identical functional and performance specifications for this application. The series difference does not affect interchangeability.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components carry identical compliance status: RoHS non-compliant, REACH Unaffected, and EAR99 ECCN classification. Both are suitable for aerospace, defense, and marine applications.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on matching coil voltage (26.5VDC), contact form (SPDT), contact rating (1A), switching voltage (115VAC, 28VDC - Max), coil current (13.3 mA), non-latching operation, through-hole mounting, PC pin termination, operating temperature range (-65°C ~ 125°C), hermetic seal rating, and coil resistance (2 kOhms).

Q: Which part should be selected if both are available?

A: Selection may be based on inventory availability, procurement lead times, or design documentation requirements. The J1MACT-26XPS currently maintains higher inventory (928 units) compared to the J1MSCT-26XM (716 units). Both parts are functionally equivalent.

Q: Are the operate and release times identical between these relays?

A: Yes. Both components operate in 2 ms and release in 4 ms. Must-operate voltage is 14.4 VDC and must-release voltage is 1.25 VDC for both parts.

Q: What is the packaging format for these relays?

A: Both components are supplied in Bulk packaging with through-hole PC pin termination suitable for printed circuit board assembly.
