ELXM079G0 Equivalent & Substitute Parts

Part Overview

The ELXM079G0 is a 7-position wire-to-board terminal block manufactured by Amphenol PCD, designed for vertical PCB mounting with top entry wire connection. This component is classified as Active product status and is RoHS Compliant. Terminal blocks of this specification are essential in applications requiring reliable electrical connections between external wiring and printed circuit boards. Substitute parts may be required due to inventory availability, lead time constraints, or specific application requirements such as mating orientation or operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELXM079G0 is determined by the following critical parameters:

• 7 positions per level (fixed requirement)
• 0.138" (4.60mm) pitch spacing (fixed requirement)
• 12 A current rating (fixed requirement)
• 300 V voltage rating (fixed requirement)
• 16-28 AWG wire gauge compatibility (fixed requirement)
• Through hole mounting (fixed requirement)
• Screw-based wire termination with rising cage clamp mechanism (fixed requirement)

The substitute part 0393570007 (Molex Eurostyle 39357) meets all critical electrical and mechanical parameters. The primary difference is mating orientation: the main part features vertical top entry, while the substitute features horizontal side entry. This orientation difference does not affect electrical performance but impacts physical board layout integration.

Parameter Comparison

Engineering Selection Recommendations

Both the ELXM079G0 and 0393570007 are Active product status components with current RoHS compliance certifications. The ELXM079G0 supports a maximum operating temperature of 125°C, while the 0393570007 operates within -40°C to 105°C. Selection between these parts depends on application thermal requirements. The ELXM079G0 is suitable for high-temperature environments; the 0393570007 is suitable for wide temperature range applications including low-temperature operation. Both components meet the same electrical specifications (12 A, 300 V) and wire gauge requirements (16-28 AWG). The primary design consideration is mating orientation: vertical top entry versus horizontal side entry. PCB layout constraints will determine which orientation is appropriate for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 0393570007 directly replace the ELXM079G0 in all applications?

A: Electrical compatibility is confirmed across all critical parameters. However, the mating orientation differs: ELXM079G0 features vertical top entry while 0393570007 features horizontal side entry. PCB layout and connector routing must accommodate this orientation difference.

Q: What is the significance of the pitch specification?

A: The 0.138" (4.60mm) pitch defines the center-to-center spacing between adjacent positions. Both parts share identical pitch, ensuring compatible PCB footprints and wire routing patterns.

Q: Are there temperature limitations when substituting?

A: The ELXM079G0 operates to 125°C maximum; the 0393570007 operates to 105°C maximum. Applications requiring sustained operation above 105°C require the ELXM079G0. Applications requiring operation below -40°C require the 0393570007.

Q: Do the screw torque specifications affect substitution?

A: The ELXM079G0 specifies 0.25 Nm (2.2 Lb-In) torque; the 0393570007 specifies 0.31 Nm (2.7 Lb-In) torque. Both values are within acceptable ranges for screw-based cage clamp termination. Assembly procedures should reference the specific torque value for each part.

Q: What packaging differences exist between these parts?

A: The ELXM079G0 is supplied in Tray packaging; the 0393570007 is supplied in Bulk packaging. This affects inventory management and handling but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. The ELXM079G0 is RoHS Compliant; the 0393570007 is ROHS3 Compliant. Both meet current regulatory requirements for restricted substance elimination.
