ELXP18100 Equivalent & Substitute Parts

Part Overview

The ELXP18100 is an 18-position terminal block plug manufactured by Amphenol PCD, featuring female sockets with 0.138" (4.60mm) pitch and 180° free-hanging in-line configuration. This component is actively produced and stocked at 1087 units. Terminal block plugs of this specification are essential in industrial control systems, automation equipment, and modular electrical interconnection applications where standardized connector interfaces are required. Substitute parts may be necessary due to supply chain constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the ELXP18100 is determined by the following critical parameters:

• Position Count & Pitch: 18 positions at 0.138" (4.60mm) spacing ensures mechanical and electrical interchangeability with mating connectors
• Connector Type: Female socket plug configuration with 180° wire entry orientation
• Termination Method: Screw-based rising cage clamp termination for consistent wire retention
• Electrical Ratings: Current and voltage specifications must meet or exceed application requirements
• Wire Gauge Compatibility: AWG range must accommodate the intended wire sizes
• Flammability & Compliance: UL94 V-0 rating and RoHS compliance are mandatory for regulated applications
• Mounting Configuration: Free-hanging in-line orientation for direct panel or backplane integration

The Phoenix Contact 1840528 qualifies as a substitute based on matching position count, pitch, connector type, wire entry orientation, termination style, and mounting configuration. Electrical and compliance parameters remain within acceptable ranges for equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELXP18100 and 1840528 are active products with current manufacturing status and full compliance certifications. Selection between these parts should be based on the following engineering criteria:

ELXP18100 (Amphenol PCD) is the primary specification. It provides 12 A UL current rating and supports 16-28 AWG wire gauge range. This part is suitable for applications requiring the specified current capacity and wire gauge compatibility.

1840528 (Phoenix Contact) serves as an equivalent substitute with identical mechanical and connector interface specifications. The UL current rating is 8 A, which is lower than the primary part. Wire gauge range extends to 14-30 AWG, providing broader compatibility for finer and heavier gauge conductors. Both parts maintain UL94 V-0 flammability rating and RoHS compliance. The Phoenix Contact part carries ROHS3 compliance designation, indicating compliance with the latest RoHS directive iteration.

Selection of the substitute should account for application current requirements. If the application operates at or below 8 A, the 1840528 provides full functional equivalence. For applications requiring current capacity above 8 A, the ELXP18100 is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the 1840528 be used as a direct replacement for the ELXP18100?

A: The 1840528 is mechanically and electrically compatible for applications operating at 8 A or below. Both parts share identical position count, pitch, connector type, wire entry orientation, and termination method. The primary difference is the UL current rating: ELXP18100 at 12 A versus 1840528 at 8 A. Verify application current requirements before substitution.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: 18-position count, 0.138" (4.60mm) pitch, female socket plug type, 180° wire entry, screw-based rising cage clamp termination, free-hanging in-line mounting, UL94 V-0 flammability rating, and RoHS compliance. Deviations in any of these parameters indicate incompatibility.

Q: Are there packaging differences between these parts?

A: Yes. The ELXP18100 is supplied in Tray packaging, while the 1840528 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical compatibility but may influence procurement, storage, and handling procedures.

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

A: The wire gauge ranges differ slightly. ELXP18100 supports 16-28 AWG, while 1840528 supports 14-30 AWG. The 1840528 accommodates finer (14 AWG) and heavier (30 AWG) gauge conductors. For applications using 16-28 AWG wire, both parts are compatible.

Q: What compliance certifications apply to each part?

A: Both parts carry UL94 V-0 flammability rating and RoHS compliance. ELXP18100 is RoHS Compliant, while 1840528 is ROHS3 Compliant. Both parts have Moisture Sensitivity Level (MSL) 1 (Unlimited) and ECCN EAR99 classification.
