J1MSPT-26XM Equivalent & Substitute Parts

Part Overview

The J1MSPT-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 1 A contact rating and is designed for through-hole mounting applications. The relay features hermetic sealing, non-latching coil operation, and integrated diode protection. Product status is Active with 1051 units currently in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when design flexibility is required within equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the J1MSPT-26XM are identified based on electrical and mechanical parameter equivalence. The primary substitution criteria include:

Critical Matching Parameters:

• Coil voltage: 26.5VDC
• Contact form: SPDT (1 Form C)
• Contact rating: 1 A
• Switching voltage: 115VAC, 28VDC - Max
• Coil current: 13.3 mA
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -65°C ~ 125°C
• Seal rating: Sealed - Hermetically
• Contact material: Silver Palladium (AgPd), Gold (Au)
• Coil resistance: 2 kOhms
• Must operate voltage: 14.4 VDC
• Must release voltage: 1.25 VDC
• Operate time: 2 ms
• Release time: 4 ms

The J1MACT-26XPS qualifies as a parametric equivalent substitute, meeting all critical electrical and mechanical specifications. The primary difference is the series designation (1MA versus 1MS), which reflects internal design variations within the TE Connectivity product family while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the J1MSPT-26XM and J1MACT-26XPS are Active products from TE Connectivity Aerospace, Defense and Marine with identical compliance profiles. Both parts carry RoHS non-compliant status, REACH Unaffected designation, and EAR99 export classification. The HTSUS code 8536.41.0050 applies to both parts.

Selection between these parts should be based on availability and inventory status. The J1MSPT-26XM maintains higher current inventory at 1051 units. The J1MACT-26XPS provides an alternative with 928 units in stock. Both parts meet all specified electrical and mechanical requirements for general purpose relay applications requiring SPDT switching at 26.5VDC coil voltage with 1 A contact rating.

The series designation difference (1MS versus 1MA) reflects internal design variations within the TE Connectivity product family. Both series operate within identical electrical parameters and environmental specifications, making them functionally interchangeable for applications meeting the specified parameter requirements.

Frequently Asked Questions (FAQ)

Q: Can J1MACT-26XPS be used as a direct replacement for J1MSPT-26XM?

A: Yes. The J1MACT-26XPS meets all critical electrical and mechanical parameters specified for the J1MSPT-26XM, including coil voltage, contact form, current rating, switching voltage, operating temperature range, and timing specifications. Both parts feature identical termination style (PC Pin), mounting type (Through Hole), and seal rating (Sealed - Hermetically).

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

A: The series designation reflects internal design variations within the TE Connectivity product family. Both 1MS and 1MA series relays operate within identical electrical specifications and environmental parameters as specified in this reference.

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

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

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

A: Substitution eligibility is determined by matching coil voltage (26.5VDC), contact form (SPDT), contact rating (1 A), switching voltage (115VAC, 28VDC - Max), coil current (13.3 mA), mounting type (Through Hole), termination style (PC Pin), operating temperature range (-65°C ~ 125°C), seal rating (Sealed - Hermetically), and timing specifications (2 ms operate, 4 ms release).

Q: Can these relays be used in applications requiring RoHS compliance?

A: No. Both the J1MSPT-26XM and J1MACT-26XPS are designated as RoHS non-compliant. Applications requiring RoHS-compliant components require alternative part selection.
