ELXM07900 Equivalent & Substitute Parts

Part Overview

The ELXM07900 is a 7-position wire-to-board terminal block manufactured by Amphenol PCD, designed for vertical top-entry PCB applications with 0.138" (4.60mm) pitch spacing. This component is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and board integration requirements can be met through alternative manufacturers while maintaining the same pitch, position count, current rating, and voltage specification.

Key Parameters

Parameter	Value
Positions Per Level	7
Pitch	0.138" (4.60mm)
Current Rating	12 A
Voltage Rating	300 V
Wire Gauge	16-28 AWG
Mounting Type	Through Hole
Wire Termination	Screw - Rising Cage Clamp
RoHS Status	RoHS Compliant

Substitute Part Grouping Explanation

Substitution eligibility for the ELXM07900 is determined by the following critical parameters:

7 positions per level configuration
0.138" (4.60mm) pitch spacing for PCB footprint compatibility
12 A current capacity
300 V voltage rating
16-28 AWG wire gauge acceptance
Through-hole mounting technology
Screw-based rising cage clamp termination method
RoHS compliance status

The substitute part 0393570007 (Molex Eurostyle 39357 series) meets all electrical and mechanical compatibility criteria. The primary difference is mating orientation: the ELXM07900 features vertical top-entry configuration, while the 0393570007 provides horizontal side-entry access. Both maintain identical pitch, position count, current/voltage ratings, wire gauge range, and termination technology.

Engineering Selection Recommendations

Selection between ELXM07900 and 0393570007 is determined by PCB layout and connector access requirements:

The ELXM07900 is specified for applications requiring vertical top-entry wire insertion, providing direct overhead access to terminal positions. This configuration is suitable for densely populated boards where side-entry access is obstructed.

The 0393570007 is specified for applications requiring horizontal side-entry wire insertion, providing lateral access to terminal positions. This configuration is suitable for edge-mounted or perimeter-mounted applications.

Both parts maintain Active product status and full regulatory compliance (RoHS and ROHS3). The ELXM07900 supports continuous operation to 125°C, while the 0393570007 operates within -40°C to 105°C range. Selection should be based on thermal environment requirements and available board space orientation.

Frequently Asked Questions (FAQ)

Q: Can the ELXM07900 and 0393570007 be used interchangeably on the same PCB?

A: No. While both parts share identical electrical ratings and pitch specifications, they differ in mating orientation. The ELXM07900 requires vertical top-entry access, while the 0393570007 requires horizontal side-entry access. PCB layout and connector positioning must accommodate the specific orientation of the selected part.

Q: Are the screw torque specifications different between these parts?

A: Yes. The ELXM07900 specifies 0.25 Nm (2.2 Lb-In) screw torque, while the 0393570007 specifies 0.31 Nm (2.7 Lb-In). Assembly procedures must use the torque value specified for the selected part number.

Q: What is the maximum operating temperature difference between these parts?

A: The ELXM07900 operates to 125°C maximum, while the 0393570007 operates to 105°C maximum. For applications exceeding 105°C, the ELXM07900 is required.

Q: Do both parts accept the same wire gauge range?

A: Yes. Both the ELXM07900 and 0393570007 accept 16-28 AWG wire gauge, ensuring wire compatibility across both part options.

Q: Are there packaging differences between these parts?

A: Yes. The ELXM07900 is supplied in Tray packaging, while the 0393570007 is supplied in Bulk packaging. Procurement and inventory management procedures should account for these packaging differences.

Q: What is the difference in contact material plating between these parts?

A: The ELXM07900 uses Brass - Tin Plated contacts, while the 0393570007 uses Copper Alloy - Tin Plated contacts. Both provide tin plating for corrosion resistance and solder compatibility.
