Substitute Part Grouping Explanation

Substitute parts for the JMACD-26XMS2 are qualified based on electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications for coil voltage (26.5VDC), contact form (DPDT), contact rating (1 A), switching voltage (115VAC, 28VDC - Max), mounting type (through hole), coil type (non-latching), seal rating (hermetically sealed), operating temperature range (-65°C to 125°C), and contact materials (silver palladium and gold).

Substitution logic is determined by the following key parameters:

Coil voltage and coil current characteristics
Contact form and current rating
Switching voltage specifications
Mounting and termination compatibility
Thermal operating range
Seal rating and contact material composition
Timing characteristics (operate and release times)

Substitute parts are grouped into two categories: parts with identical coil resistance (1.56 kOhms / 1560 Ohms) and parts with military qualification (MIL-R-39016/15). Variations in RoHS compliance status and series designation do not affect functional substitutability when all electrical and mechanical parameters remain equivalent.

Engineering Selection Recommendations

All substitute parts listed are functionally equivalent to the JMACD-26XMS2 and maintain identical electrical performance across switching voltage, coil voltage, contact rating, and timing specifications. Selection among substitute parts is determined by application-specific requirements regarding military qualification and regulatory compliance.

For applications requiring military qualification to MIL-R-39016/15, the following parts are suitable: JMACD-26XM, JMACD-26XP, JMAPD-26XM, JMAPD-26XP, JMAWD-26XL, and JMAWD-26XP.

For applications requiring RoHS3 compliance, JMAPD-26XM and JMAWD-26XL are available. These parts maintain all electrical and mechanical specifications while meeting RoHS3 requirements.

Parts without military qualification or RoHS compliance include JMACDG-26XM, JMAPD-26XL, JMAPD-26XP, and PRMAPD-26X. These parts are suitable for general commercial applications where military qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can JMACD-26XM be used as a direct replacement for JMACD-26XMS2?

A: Yes. JMACD-26XM is functionally equivalent with identical coil voltage (26.5VDC), contact form (DPDT), contact rating (1 A), switching voltage (115VAC, 28VDC - Max), operating temperature range (-65°C to 125°C), and timing characteristics. The primary difference is military qualification to MIL-R-39016/15, which does not affect functional substitutability in applications where military certification is not required.

Q: What is the difference between parts with 1.56 kOhms and 1560 Ohms coil resistance?

A: These values are equivalent. 1.56 kOhms equals 1560 Ohms. Both represent the same coil resistance specification and do not affect substitutability.

Q: Are RoHS3 compliant parts (JMAPD-26XM, JMAWD-26XL) suitable for non-RoHS applications?

A: Yes. RoHS3 compliant parts meet or exceed RoHS non-compliant specifications and are suitable for all applications. RoHS compliance is an additional qualification that does not restrict use in non-RoHS applications.

Q: Do all substitute parts use the same contact materials?

A: Yes. All substitute parts use silver palladium (AgPd) and gold (Au) contact materials, identical to the JMACD-26XMS2.

Q: Can parts from different series (MAC, MAD, CII, PRMAPD) be interchanged?

A: Yes, when all electrical and mechanical parameters are identical. Series designation indicates manufacturing lineage but does not affect functional compatibility when coil voltage, contact form, contact rating, switching voltage, mounting type, seal rating, and operating temperature specifications are equivalent.

Q: What is the significance of the "G" suffix in JMACDG-26XM?

A: The "G" suffix indicates a variant within the JMACD series. JMACDG-26XM maintains identical electrical and mechanical specifications to JMACD-26XMS2 and is functionally equivalent.

Q: Are all substitute parts hermetically sealed?

A: Yes. All substitute parts maintain hermetically sealed construction, identical to the JMACD-26XMS2.

Q: What is the coil current for all these relays?

A: The coil current is 17 mA for all parts listed, including the JMACD-26XMS2 and all substitute parts where this specification is provided.
