J1MSCD-5XMS General Purpose Relay SPDT Equivalent & Substitute Parts

Part Overview

The J1MSCD-5XMS is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This Single Pole Double Throw (SPDT) relay operates at 5VDC with a 1A contact rating and is designed for through-hole mounting applications. The relay features hermetically sealed construction with integrated diode protection and operates across an extended temperature range of -65°C to 125°C.

The J1MSCD-5XMS maintains Active product status with 1024 units currently in stock. Substitute parts are identified based on identical electrical specifications, mechanical compatibility, and functional equivalence within the 1MS relay series.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the J1MSCD-5XMS are identified through parametric equivalence within the TE Connectivity 1MS relay series. Substitution is valid when all critical electrical and mechanical parameters remain identical:

Critical Substitution Parameters:

• Coil voltage: 5VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 1 A
• Switching voltage: 115VAC, 28VDC maximum
• Coil current: 40 mA
• Mounting type: Through hole
• Termination style: PC pin
• Operating temperature range: -65°C to 125°C
• Coil resistance: 125 Ohms
• Seal rating: Hermetically sealed
• Contact material composition: Silver Palladium and Gold

The J1MSWD-5XM is a direct parametric equivalent within the 1MS series, differing only in base product designation (J1MSW versus J1MSC) while maintaining identical functional and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the J1MSCD-5XMS and J1MSWD-5XM are Active status products from TE Connectivity Aerospace, Defense and Marine. Selection between these parts is based on availability and supply chain considerations rather than functional differences.

J1MSCD-5XMS is the primary specification with 1024 units in current inventory, providing established supply availability.

J1MSWD-5XM is a direct parametric equivalent with 640 units in current inventory, suitable for use when primary stock is unavailable.

Both parts share identical compliance profiles: RoHS non-compliant status, REACH Unaffected designation, EAR99 export classification, and HTSUS code 8536.41.0050. Both maintain Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can J1MSWD-5XM be used as a direct replacement for J1MSCD-5XMS?

A: Yes. The J1MSWD-5XM is a parametric equivalent with identical electrical specifications, mechanical dimensions, and functional characteristics. All critical parameters including coil voltage, contact form, current rating, switching voltage, operating temperature range, and timing specifications are identical.

Q: What is the difference between J1MSCD-5XMS and J1MSWD-5XM?

A: The parts differ only in base product designation (J1MSC versus J1MSW). All electrical, mechanical, and performance parameters are identical. Both are manufactured by TE Connectivity within the 1MS relay series.

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

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Unaffected, EAR99 export classification, and HTSUS code 8536.41.0050. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the through-hole PC pin termination style?

A: PC pin termination refers to printed circuit board pins designed for insertion into plated through-holes on circuit boards. This mounting style is standard for both the J1MSCD-5XMS and J1MSWD-5XM.

Q: Can these relays operate below 5VDC?

A: Yes. The must-operate voltage is 2.8VDC, indicating the relay will energize at voltages as low as 2.8VDC. The must-release voltage is 0.23VDC, indicating the relay will de-energize when coil voltage drops below this threshold.

Q: What is the hermetically sealed construction?

A: Hermetically sealed construction provides a completely sealed enclosure that prevents moisture and contaminant ingress. This design is suitable for aerospace, defense, and marine applications requiring high reliability in harsh environments.

Q: Are these relays suitable for aerospace and defense applications?

A: Yes. Both parts are manufactured by TE Connectivity Aerospace, Defense and Marine and are designed to meet the requirements of these industries. The hermetically sealed construction, extended operating temperature range (-65°C to 125°C), and integrated diode protection support aerospace and defense specifications.
