JMACD-26XPS General Purpose Relay DPDT Equivalent & Substitute Parts

Part Overview

The JMACD-26XPS is a general purpose relay manufactured by TE Connectivity Aerospace, Defense and Marine. This hermetically sealed, through-hole mounted DPDT (2 Form C) relay operates at 26.5VDC coil voltage with a 1 A contact rating. The part is classified as Active product status and is designed for applications requiring switching of 115VAC or 28VDC maximum loads. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the relay series, enabling component interchangeability in circuit designs where the original part number becomes unavailable or when alternative packaging or compliance requirements necessitate alternative selection.

Substitute Part Grouping Explanation

Substitute parts for the JMACD-26XPS are qualified based on strict equivalence of the following critical parameters: coil voltage (26.5VDC), contact form (DPDT), contact rating (1 A), switching voltage capability (115VAC, 28VDC maximum), mounting type (through hole), coil type (non-latching), termination style (PC pin), seal rating (hermetically sealed), operating temperature range (-65°C to 125°C), and contact material composition (Silver Palladium and Gold). All substitute parts maintain these electrical and mechanical specifications. Variations in coil resistance (1.56 kOhms versus 1560 Ohms), series designation, military grade qualification, and RoHS compliance status do not preclude substitution when the core functional parameters remain identical. Parts are grouped by base product number families: JMACD, JMACDG, JMAPD, JMAWD, and PRMAPD series.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the JMACD-26XPS. Selection among substitute parts should be based on product availability, compliance requirements, and series designation applicable to the end application.

JMACD-26XM, JMACD-26XP, and JMACDG-26XM are qualified to MIL-R-39016/15 military specification and carry military grade designation. These parts are suitable for aerospace, defense, and marine applications requiring military qualification.

JMAPD-26XL, JMAPD-26XM, and JMAPD-26XP represent the JMAPD series family. JMAPD-26XM is RoHS3 compliant, while JMAPD-26XL and JMAPD-26XP maintain RoHS non-compliant status.

JMAWD-26XL and JMAWD-26XP represent the JMAWD series family. JMAWD-26XL is RoHS3 compliant with REACH status listed as Vendor Undefined. JMAWD-26XP is RoHS non-compliant with REACH Unaffected status.

PRMAPD-26X represents the PRMAPD series and maintains RoHS non-compliant status with REACH Unaffected designation.

The original JMACD-26XPS part is RoHS non-compliant. When RoHS3 compliance is required, JMAPD-26XM or JMAWD-26XL are direct functional equivalents with enhanced environmental compliance.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical electrical parameters: 26.5VDC coil voltage, DPDT contact form, 1 A contact rating, 115VAC/28VDC switching voltage, hermetically sealed construction, and -65°C to 125°C operating temperature range. The primary difference is military grade qualification (MIL-R-39016/15) on JMACD-26XM.

Q: What is the difference between JMAPD-26XL and JMAPD-26XM?

A: Both parts are electrically and mechanically equivalent with identical coil voltage, contact form, current rating, and switching specifications. JMAPD-26XM is RoHS3 compliant, while JMAPD-26XL is RoHS non-compliant. Selection depends on environmental compliance requirements of the application.

Q: Are all substitute parts hermetically sealed?

A: Yes. All substitute parts listed maintain hermetically sealed construction, matching the JMACD-26XPS seal rating specification.

Q: Can PRMAPD-26X be used in place of JMACD-26XPS?

A: Yes. PRMAPD-26X maintains all critical electrical and mechanical parameters: 26.5VDC coil voltage, DPDT contact form, 1 A contact rating, 115VAC/28VDC switching voltage, through-hole mounting, PC pin termination, hermetic sealing, and -65°C to 125°C operating temperature. The part number prefix indicates series designation but does not affect functional equivalence.

Q: What does the suffix letter designation (M, P, L, X) indicate?

A: Suffix letters represent packaging or configuration variants within the relay series. All variants listed maintain identical electrical specifications and are functionally interchangeable.

Q: Are military-qualified parts (MIL-R-39016/15) required for all applications?

A: Military qualification is application-dependent. Parts bearing MIL-R-39016/15 qualification (JMACD-26XM, JMACD-26XP, JMAPD-26XM, JMAPD-26XP, JMAWD-26XL, JMAWD-26XP) are suitable for aerospace, defense, and marine applications requiring military specification compliance. Non-qualified parts are suitable for general industrial applications.

Q: What is the significance of RoHS compliance status in relay selection?

A: RoHS compliance status indicates environmental and hazardous substance restrictions applicable to the component. RoHS3 compliant parts (JMAPD-26XM, JMAWD-26XL) meet current environmental regulations and are preferred for applications subject to RoHS directives. RoHS non-compliant parts remain functionally equivalent but may not be suitable for regulated markets.

Q: Can substitute parts be mixed in the same circuit board design?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably in circuit designs. However, design documentation should specify the approved part number list to ensure procurement consistency.
