J1MSWD-5XP General Purpose Relay SPDT Equivalent & Substitute Parts

Part Overview

The J1MSWD-5XP is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This SPDT (Single Pole Double Throw) 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 J1MSWD-5XP maintains active product status with 1022 units currently in stock. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and access to alternative inventory sources when the primary part number becomes unavailable or when procurement requirements necessitate alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the J1MSWD-5XP are identified based on electrical and mechanical parameter equivalence within the 1MS relay series. The substitution logic is based on the following critical parameters that must remain identical:

• Coil Voltage: 5VDC
• Contact Form: SPDT (1 Form C)
• Contact Rating (Current): 1 A
• Switching Voltage: 115VAC, 28VDC - Max
• Coil Current: 40 mA
• Coil Type: Non Latching
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -65°C ~ 125°C
• Coil Resistance: 125 Ohms
• Seal Rating: Sealed - Hermetically
• Contact Material: Silver Palladium (AgPd), Gold (Au)
• Features: Diode

Parts meeting all these parameter specifications are classified as parametric equivalents and direct substitutes. The J1MSWD-5XM is identified as a parametric equivalent within the 1MS series, sharing identical electrical characteristics, mechanical configuration, and performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the J1MSWD-5XP and J1MSWD-5XM are active products manufactured by TE Connectivity Aerospace, Defense and Marine within the 1MS relay series. These parts are parametric equivalents with identical electrical specifications, mechanical configurations, and performance characteristics.

Selection between these parts should be based on inventory availability and procurement lead times. The J1MSWD-5XP currently maintains higher inventory levels at 1022 units in stock, while the J1MSWD-5XM has 640 units available. Both parts share identical compliance status, including RoHS non-compliance, REACH unaffected designation, and EAR99 export classification.

For applications requiring hermetically sealed SPDT relays with 5VDC coil operation, 1A contact rating, and through-hole PC pin termination, either part number provides equivalent performance and functionality. The choice between these substitutes is determined by supply chain requirements and inventory considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

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

A: Yes. The J1MSWD-5XM is a parametric equivalent with identical coil voltage (5VDC), contact form (SPDT), current rating (1A), switching voltage (115VAC, 28VDC max), coil current (40 mA), operating temperature range (-65°C to 125°C), and all other electrical and mechanical specifications. Direct substitution is supported without circuit modification.

Q: Are there any differences in the physical package or mounting between these parts?

A: No. Both parts feature identical through-hole mounting configuration with PC pin termination style. The physical package dimensions and pin spacing are equivalent, allowing direct board-level substitution.

Q: What is the significance of the hermetically sealed construction?

A: Hermetically sealed construction provides protection against moisture ingress and environmental contamination. Both the J1MSWD-5XP and J1MSWD-5XM feature sealed hermetic construction, ensuring reliable operation in harsh environments and extended storage conditions.

Q: Do these relays include any protection features?

A: Yes. Both parts include integrated diode protection, which suppresses inductive kickback voltage when the coil is de-energized. This feature protects downstream circuitry from voltage transients.

Q: What is the coil resistance specification, and why is it important?

A: Both parts have a coil resistance of 125 Ohms at 5VDC. This specification determines the coil current draw (40 mA) and is critical for proper circuit design and power supply sizing.

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

A: Both parts are manufactured by TE Connectivity Aerospace, Defense and Marine and carry EAR99 export classification. They are designed for demanding applications requiring reliable switching performance across extended temperature ranges.

Q: What is the operating time specification?

A: Both relays have an operate time of 4 milliseconds, representing the time required for the relay contacts to transition from open to closed state after coil energization. Release time is 7.5 milliseconds.

Q: How do the must-operate and must-release voltage specifications affect circuit design?

A: The must-operate voltage of 2.8VDC indicates the minimum coil voltage required to guarantee relay activation. The must-release voltage of 0.23VDC specifies the maximum coil voltage at which the relay is guaranteed to release. These specifications define the operating window for reliable relay control.
