Engineering Selection Recommendations

Active Substitute Parts

JMAC-26XM, JMAC-26XP, and JMAW-26XL are currently active products with continuous availability. JMAC-26XM and JMAW-26XL carry ROHS3 compliance status, while JMAC-26XP maintains RoHS non-compliant status consistent with the original JMACG-26XMS. All three active substitutes are military-grade relays qualified to MIL-R-39016/9 specification.

Discontinued Substitute Parts

PRMAC-26XS and PRMAC-26Y are discontinued at DiGi Electronics but remain available in inventory. These parts maintain electrical and mechanical equivalence to the JMACG-26XMS and carry identical RoHS non-compliant status. Both PRMAC series parts are suitable for applications where military qualification is not required.

Compliance Considerations

For applications requiring RoHS3 compliance, JMAC-26XM or JMAW-26XL are appropriate selections. For applications with existing RoHS non-compliant component specifications, JMAC-26XP, PRMAC-26XS, or PRMAC-26Y maintain compliance alignment with the original JMACG-26XMS.

Frequently Asked Questions (FAQ)

Q: Can JMAC-26XM, JMAC-26XP, and JMAW-26XL be used interchangeably with JMACG-26XMS?

A: Yes. All three parts maintain identical electrical and mechanical parameters including coil voltage, contact form, contact rating, switching voltage, operating temperature range, and timing specifications. The parts are functionally equivalent for circuit applications.

Q: What is the difference between the military-grade JMAC series and the PRMAC series substitutes?

A: The JMAC series (JMAC-26XM, JMAC-26XP, JMAW-26XL) are military-grade relays qualified to MIL-R-39016/9 specification. The PRMAC series (PRMAC-26XS, PRMAC-26Y) are commercial-grade relays without military qualification. Both series maintain identical electrical and mechanical specifications for the 26.5 VDC DPDT 1 A relay configuration.

Q: Are there RoHS compliance differences among the substitute parts?

A: Yes. JMAC-26XM and JMAW-26XL are ROHS3 compliant. JMAC-26XP, PRMAC-26XS, and PRMAC-26Y are RoHS non-compliant, matching the original JMACG-26XMS status. Component selection should align with the RoHS compliance requirements of the target application.

Q: Which substitute part has the highest current inventory availability?

A: PRMAC-26Y has the highest inventory with 850 pieces in stock, followed by JMAC-26XM with 927 pieces. JMAC-26XP has 706 pieces, PRMAC-26XS has 667 pieces, and JMAW-26XL has 659 pieces available.

Q: Are all substitute parts through-hole mounted with PC pin termination?

A: Yes. All substitute parts maintain through-hole mounting type with PC pin termination style, ensuring mechanical compatibility with existing printed circuit board designs.

Q: What is the coil resistance specification for each substitute part?

A: JMAC-26XM, JMAC-26XP, and JMAW-26XL specify 1560 Ohms coil resistance. PRMAC-26XS and PRMAC-26Y specify 1.56 kOhms coil resistance, which is equivalent to 1560 Ohms.

Q: Can substitute parts be used in aerospace and defense applications?

A: The military-grade JMAC series parts (JMAC-26XM, JMAC-26XP, JMAW-26XL) are qualified for aerospace and defense applications with MIL-R-39016/9 certification. The PRMAC series parts are suitable for commercial applications. Application requirements should determine the appropriate selection.
