Engineering Selection Recommendations

The JMACT-26XPS maintains Active product status with established supply availability (802 pieces in stock). The component carries RoHS non-compliant designation and REACH Unaffected status, which are material considerations for applications subject to regulatory compliance requirements.

Selection of alternative components should be based on:

1. Product Status Alignment: Substitute parts must maintain Active status to ensure continued manufacturability and supply chain stability.

2. Regulatory Compliance: Applications requiring RoHS compliance will require alternative components with RoHS compliant designation. The JMACT-26XPS is not suitable for such applications.

3. Certification Requirements: The REACH Unaffected status of the JMACT-26XPS indicates no restriction under REACH regulations. Substitute parts should maintain equivalent or superior regulatory standing.

4. Electrical Parameter Matching: All critical parameters including coil voltage, contact form, contact rating, and switching voltage must align precisely with application requirements.

5. Environmental Specifications: The extended operating temperature range (-65°C to 125°C) and hermetic sealing are critical for aerospace, defense, and marine applications and must be maintained in any substitute selection.

Frequently Asked Questions (FAQ)

Q: What makes the JMACT-26XPS suitable for aerospace and defense applications?

A: The JMACT-26XPS features hermetic sealing, extended operating temperature range (-65°C to 125°C), integrated diode protection, and contact materials (Silver Palladium and Gold) that provide reliability in demanding environments. These characteristics are standard for TE Connectivity Aerospace, Defense and Marine product lines.

Q: Can the JMACT-26XPS be used in RoHS-compliant applications?

A: No. The JMACT-26XPS carries RoHS non-compliant designation and is not suitable for applications requiring RoHS compliance. Alternative RoHS-compliant relay components must be selected for such applications.

Q: What are the critical parameters for substituting the JMACT-26XPS?

A: Substitute parts must match the following parameters: DPDT (2 Form C) contact form, 26.5VDC coil voltage, 1A contact rating, 115VAC/28VDC maximum switching voltage, through-hole mounting with PC pin termination, hermetic sealing, -65°C to 125°C operating temperature range, non-latching coil type, and integrated diode protection.

Q: What is the significance of the 1.56 kOhms coil resistance specification?

A: The coil resistance of 1.56 kOhms, combined with the 26.5VDC coil voltage, determines the nominal coil current of 17 mA. This parameter is critical for circuit design and power supply dimensioning in applications using the JMACT-26XPS.

Q: How do the operate and release times affect circuit design?

A: The operate time of 2 ms and release time of 7.5 ms define the switching response characteristics of the relay. These timing parameters must be considered in applications requiring specific switching speed or synchronization with other circuit elements.

Q: What does "Must Operate Voltage" and "Must Release Voltage" indicate?

A: Must Operate Voltage (14.2 VDC) is the minimum coil voltage at which the relay is guaranteed to energize. Must Release Voltage (1.37 VDC) is the maximum coil voltage at which the relay is guaranteed to de-energize. These parameters define the operational voltage window for reliable relay function.

Q: Is the JMACT-26XPS affected by REACH regulations?

A: No. The JMACT-26XPS carries REACH Unaffected status, indicating that REACH regulations do not apply to this component. This status simplifies compliance documentation for applications subject to REACH requirements.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 (Unlimited) indicates that the JMACT-26XPS has no moisture sensitivity restrictions. The component can be stored and handled without special moisture control measures, simplifying logistics and inventory management.
