Engineering Selection Recommendations
JMAC-26XM: This substitute is qualified to MIL-R-39016/9 and carries ROHS3 compliance. It is actively available with 927 pieces in stock. Selection of JMAC-26XM is appropriate for applications requiring military-grade qualification and RoHS3 compliance.
JMAC-26XP: This substitute is qualified to MIL-R-39016/9 with military-grade designation. It maintains RoHS non-compliant status matching the PRMAP-26X. It is actively available with 706 pieces in stock. Selection of JMAC-26XP is appropriate for military applications where RoHS compliance is not a requirement.
JMAW-26XL: This substitute is qualified to MIL-R-39016/9 and carries ROHS3 compliance. It is actively available with 659 pieces in stock. Selection of JMAW-26XL is appropriate for applications requiring military-grade qualification and RoHS3 compliance.
PRMAC-26XS: This substitute maintains the same series characteristics as PRMAP-26X with identical coil resistance specification (1.56 kOhms) and RoHS non-compliant status. However, it is discontinued at DiGi Electronics. Selection of PRMAC-26XS is limited to existing inventory applications where 667 pieces remain available.
PRMAC-26Y: This substitute maintains the same series characteristics as PRMAP-26X with identical coil resistance specification (1.56 kOhms) and RoHS non-compliant status. However, it is discontinued at DiGi Electronics. Selection of PRMAC-26Y is limited to existing inventory applications where 850 pieces remain available.
For new designs, JMAC-26XM or JMAW-26XL are preferred due to active product status and RoHS3 compliance. For applications requiring military qualification without RoHS compliance, JMAC-26XP is available. The PRMAC series substitutes are suitable only for replacement of existing PRMAP-26X installations where inventory depletion necessitates alternative sourcing.
Frequently Asked Questions (FAQ)
Q: Can JMAC-26XM be used as a direct replacement for PRMAP-26X?
A: Yes. JMAC-26XM meets all electrical and mechanical parameters of PRMAP-26X, including coil voltage (26.5VDC), contact form (DPDT), current rating (1 A), switching voltage (115VAC, 28VDC - Max), operating temperature range (-65°C ~ 125°C), and termination style (PC Pin). The primary differences are military qualification (MIL-R-39016/9) and RoHS3 compliance, which represent enhancements rather than deviations.
Q: What is the difference between JMAC-26XM and JMAC-26XP?
A: Both parts are qualified to MIL-R-39016/9 and share identical electrical and mechanical specifications. The difference is RoHS compliance status: JMAC-26XM is ROHS3 compliant, while JMAC-26XP is RoHS non-compliant. Selection depends on regulatory requirements of the application.
Q: Why are PRMAC-26XS and PRMAC-26Y marked as discontinued?
A: Both parts are discontinued at DiGi Electronics, indicating they are no longer actively produced or distributed through primary channels. However, inventory remains available (667 and 850 pieces respectively). These parts are suitable only for replacement applications where existing stock is available.
Q: Are all substitute parts through-hole mounted?
A: Yes. All substitute parts (JMAC-26XM, JMAC-26XP, JMAW-26XL, PRMAC-26XS, PRMAC-26Y) use through-hole mounting with PC pin termination, matching the PRMAP-26X mounting configuration.
Q: What is the coil resistance of each substitute part?
A: JMAC-26XM, JMAC-26XP, and JMAW-26XL specify coil resistance as 1560 Ohms. PRMAC-26XS and PRMAC-26Y specify coil resistance as 1.56 kOhms. These values are equivalent (1560 Ohms = 1.56 kOhms) and match the PRMAP-26X specification of 1.56 kOhms.
Q: Which substitute part has the highest inventory availability?
A: JMAC-26XM has the highest inventory with 927 pieces in stock, followed by PRMAC-26Y with 850 pieces. Both are suitable for immediate procurement.
Q: Can JMAW-26XL be used in applications requiring RoHS compliance?
A: Yes. JMAW-26XL carries ROHS3 compliance status and is qualified to MIL-R-39016/9. It is suitable for applications with RoHS compliance requirements.
Q: Are all substitute parts hermetically sealed?
A: Yes. All substitute parts maintain the sealed hermetically rating of the PRMAP-26X, providing equivalent environmental protection.
