ELMP03150 Equivalent & Substitute Parts

Part Overview

The ELMP03150 is a 3-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with 15mm (0.591") pitch spacing. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The terminal block accommodates wire gauges from 4-16 AWG with a rated current capacity of 75A at 600V, utilizing screw-based rising cage clamp termination for secure wire connections.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELMP03150 are qualified based on the following critical parameters that determine functional equivalence:

• Pitch and Position Count: All substitutes maintain 0.591" (15.00mm) pitch with 3 positions per level, ensuring PCB footprint compatibility
• Mating Orientation and Mounting: All substitutes are horizontal with board orientation and through-hole mounting, maintaining mechanical compatibility
• Wire Termination Method: All substitutes use screw-based rising cage clamp termination, preserving installation and maintenance procedures
• Voltage Rating: All substitutes maintain 600V rating, meeting electrical system requirements
• Housing Material: All substitutes use polyamide/nylon housing, maintaining environmental and mechanical properties

The identified substitutes (1932504 and 1986242-3) meet these core compatibility criteria while offering enhanced current ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

1986242-3 (TE Connectivity AMP Connectors) is the primary substitute for ELMP03150 applications. This part maintains active product status with ROHS3 compliance, offers the highest current rating (125A), and supports the widest wire gauge range (1-20 AWG). The operating temperature range (-40°C ~ 105°C) covers the lower end of the original specification, making it suitable for most industrial applications. The higher torque specification (3.4 Nm) provides enhanced screw retention characteristics.

1932504 (Phoenix Contact COMBICON MKDSP) serves as an alternative substitute with active product status and ROHS3 compliance. This part provides 115A current capacity and supports wire gauges from 2-20 AWG. The flange-mounted feature offers additional mechanical stability for applications requiring enhanced mounting security. The torque range (2.5-4.5 Nm) provides flexibility in installation procedures.

Both substitutes are electrically and mechanically compatible with the ELMP03150 for applications operating within the specified voltage (600V) and pitch (15mm) parameters. Selection between the two substitutes should be based on specific application requirements regarding current capacity, wire gauge compatibility, and mounting configuration preferences.

Frequently Asked Questions (FAQ)

Q: Can 1986242-3 or 1932504 be used as direct replacements for ELMP03150 in existing PCB designs?

A: Yes. Both substitutes maintain identical pitch (15mm), position count (3), mating orientation (horizontal with board), and mounting type (through hole). PCB footprints are compatible without modification.

Q: What is the significance of the higher current ratings in the substitute parts?

A: The substitute parts (115A for 1932504 and 125A for 1986242-3) exceed the original 75A rating. This provides design margin and allows the substitutes to handle higher current loads without thermal stress, extending component life in demanding applications.

Q: Are there differences in wire gauge compatibility?

A: Yes. The ELMP03150 accepts 4-16 AWG wire. The 1986242-3 accepts 1-20 AWG, and the 1932504 accepts 2-20 AWG. Both substitutes support a wider range, allowing connection of smaller and larger gauge conductors within the same terminal block footprint.

Q: How do the torque specifications affect installation?

A: The ELMP03150 specifies 2.26 Nm (20 Lb-In) torque. The 1986242-3 requires 3.4 Nm (30 Lb-In), and the 1932504 specifies a range of 2.5-4.5 Nm (22.1-39.8 Lb-In). Higher torque values indicate stronger screw retention. Installation procedures must use the specified torque values to ensure proper clamping force without over-tightening.

Q: What is the difference between RoHS and ROHS3 compliance?

A: The ELMP03150 is RoHS Compliant (RoHS 1). Both substitutes are ROHS3 Compliant (RoHS 3), which includes additional restricted substances and represents current regulatory standards. ROHS3 compliance is a superset of RoHS 1 requirements, making these parts suitable for applications requiring either standard.

Q: Does the operating temperature difference between ELMP03150 (-40°C ~ 120°C) and 1986242-3 (-40°C ~ 105°C) affect substitution?

A: The 1986242-3 upper temperature limit is 15°C lower than the original. For applications operating below 105°C, this substitution is valid. Applications requiring operation above 105°C should use the 1932504, for which operating temperature is not specified, or verify thermal performance with the manufacturer.

Q: What is the significance of the flange feature on the 1932504?

A: The flange provides additional mechanical mounting surface for enhanced board-level stability. This feature is beneficial in applications with vibration or mechanical stress but is not required for standard PCB mounting. The flange does not affect electrical compatibility.
