J1MSPD-12XM Equivalent & Substitute Parts

Part Overview

The J1MSPD-12XM is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This SPDT (Single Pole Double Throw) relay operates at 12VDC with a 1A contact rating and is designed for through-hole mounting applications. The device features hermetic sealing, integrated diode protection, and operates across an extended temperature range of -65°C to 125°C. The part is currently active in production with 894 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require alternative component selection.

Substitute Part Grouping Explanation

The J1MSCD-12XL is identified as a parametric equivalent to the J1MSPD-12XM based on strict alignment of electrical and mechanical specifications. Both parts share identical values across all critical substitution parameters: 12VDC coil voltage, SPDT contact configuration, 1A contact rating, 115VAC/28VDC maximum switching voltage, 11.7mA coil current, through-hole mounting, hermetic sealing, -65°C to 125°C operating temperature range, and 1.025 kOhms coil resistance. Both relays feature non-latching coil operation with integrated diode protection and identical contact material composition (Silver Palladium and Gold). The substitution is valid based on these matching electrical and mechanical parameters, which determine functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the J1MSPD-12XM and J1MSCD-12XL are active production parts from TE Connectivity Aerospace, Defense and Marine with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status. The J1MSPD-12XM currently has 894 units in stock, while the J1MSCD-12XL has 815 units available. Both parts carry identical compliance designations (EAR99 export classification and HTSUS code 8536.41.0050). The J1MSPD-12XM is RoHS non-compliant with MSL rating of 1 (Unlimited), while the J1MSCD-12XL is REACH Unaffected with MSL listed as Not Applicable. For applications requiring RoHS compliance or specific moisture sensitivity level documentation, compliance requirements should be evaluated against project specifications. Both relays are suitable for general purpose switching applications requiring 12VDC coil operation, 1A contact capacity, and hermetic sealing across the -65°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the J1MSCD-12XL be used as a direct replacement for the J1MSPD-12XM?

A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications across all critical parameters including coil voltage, contact form, current rating, switching voltage, operating temperature range, and coil resistance. Direct substitution is valid from an electrical and mechanical standpoint.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching values in the following parameters: coil voltage (12VDC), contact form (SPDT), contact rating (1A), switching voltage (115VAC/28VDC max), coil current (11.7mA), mounting type (through-hole), seal rating (hermetically sealed), operating temperature range (-65°C to 125°C), and coil resistance (1.025 kOhms). Both parts match across all these parameters.

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

A: Both parts share identical export classification (EAR99) and HTSUS codes (8536.41.0050). The J1MSPD-12XM is RoHS non-compliant with MSL 1 (Unlimited), while the J1MSCD-12XL is REACH Unaffected with MSL listed as Not Applicable. Project-specific compliance requirements should be evaluated when selecting between these parts.

Q: Do both parts use the same contact material?

A: Yes. Both the J1MSPD-12XM and J1MSCD-12XL use Silver Palladium (AgPd) and Gold (Au) contact materials, ensuring identical contact performance and reliability characteristics.

Q: What is the difference between the base product numbers J1MSP and J1MSC?

A: The base product numbers indicate different product lines within the 1MS series from TE Connectivity. However, the J1MSPD-12XM and J1MSCD-12XL are parametric equivalents with identical electrical and mechanical specifications, making them functionally interchangeable for circuit applications.

Q: Are the timing characteristics identical between these relays?

A: Yes. Both parts have identical operate time (4 ms) and release time (7.5 ms), as well as matching must-operate voltage (7 VDC) and must-release voltage (0.63 VDC) specifications.

Q: Which part should be selected based on current inventory?

A: The J1MSPD-12XM has higher current inventory (894 units) compared to the J1MSCD-12XL (815 units). Selection should be based on project delivery requirements and inventory availability at the time of procurement.
