Selection among these equivalents may be based on packaging designation, inventory availability, or specific application requirements where moisture sensitivity level (MSL) specifications are relevant.

Frequently Asked Questions (FAQ)

Q: Can JMACDD-26XL be used as a direct replacement for JMACDD-26XM?

A: Yes. JMACDD-26XL is a parametric equivalent with identical electrical and mechanical specifications. Both parts operate at 26.5VDC coil voltage, feature DPDT contact form, 1 A contact rating, and maintain the same operating temperature range and switching characteristics.

Q: What is the difference between JMACDD-26XM and JMACDD-26XPS2?

A: The parts are electrically and mechanically identical. The designation difference reflects packaging and moisture sensitivity level (MSL) specifications. Both maintain hermetically sealed construction and identical performance parameters.

Q: Is 1617542-8 compatible with JMACDD-26XM applications?

A: Yes. Part number 1617542-8 is a parametric equivalent within the MAC series. It provides identical coil voltage, contact form, current rating, switching voltage, and operating characteristics. Through-hole mounting and PC pin termination are identical.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All substitute parts operate across -65°C to 125°C, matching the JMACDD-26XM specification.

Q: Are there differences in contact material between the main part and substitutes?

A: No. All parts use Silver Palladium (AgPd) and Gold (Au) contact materials with identical coil resistance of 1.56 kOhms.

Q: What is the significance of the MSL rating difference?

A: JMACDD-26XM does not specify an MSL rating, while JMACDD-26XL, JMACDD-26XPS2, and 1617542-8 specify MSL 1 (Unlimited). Since all parts are hermetically sealed, this difference does not affect functional performance in sealed applications.

Q: Can these relays be used interchangeably in aerospace and defense applications?

A: All parts are manufactured by TE Connectivity Aerospace, Defense and Marine and share identical ECCN (EAR99) and HTSUS (8536.41.0050) classifications. Interchangeability depends on specific application requirements and design documentation.
