ELMP04041 Equivalent & Substitute Parts

Part Overview

The ELMP04041 is a 4-position wire-to-board terminal block manufactured by Amphenol PCD, designed for horizontal PCB mounting with side entry wire connections. This component features a 0.400" (10.16mm) pitch and through-hole mounting configuration. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The ELMP04041 can be substituted with the TE Connectivity AMP Connectors part 282843-4 based on the following critical matching parameters:

• 4 positions per level
• 0.400" (10.16mm) pitch spacing
• Horizontal with board mating orientation
• Through-hole PCB mounting
• Screw-based rising cage clamp wire termination
• Side interlocking feature
• Polyamide nylon housing material

These parameters define the mechanical and electrical interface compatibility for direct substitution in PCB applications.

Parameter Comparison

Engineering Selection Recommendations

The 282843-4 serves as a direct mechanical and electrical substitute for the obsolete ELMP04041. Both components are RoHS compliant and share identical pitch, position count, mounting orientation, and wire termination methodology.

The 282843-4 offers active product status with current availability, addressing the obsolescence constraint of the ELMP04041. The substitute maintains through-hole PCB compatibility and side-entry wire connection architecture.

Current and voltage rating differences exist between the two components. The ELMP04041 supports 60 A at 300 V, while the 282843-4 is rated for 17.5 A at 600 V. Wire gauge acceptance ranges differ: ELMP04041 accepts 8-18 AWG versus 282843-4 acceptance of 12-30 AWG. These electrical parameter variations require evaluation against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 282843-4 directly replace the ELMP04041 in existing PCB designs?

A: Mechanical and positional compatibility is confirmed. The 0.400" pitch, 4-position configuration, through-hole mounting, and side-entry screw termination are identical. Electrical parameter differences must be evaluated for your specific application requirements.

Q: What are the key differences between these two terminal blocks?

A: The primary differences are current rating (60 A vs. 17.5 A), voltage rating (300 V vs. 600 V), wire gauge range (8-18 AWG vs. 12-30 AWG), and product status (obsolete vs. active). Housing material composition differs slightly (PA vs. PA66 nylon variant).

Q: Is the 282843-4 suitable for high-current applications originally designed for the ELMP04041?

A: The 282843-4 has a lower current rating of 17.5 A compared to the ELMP04041's 60 A specification. Applications requiring the full 60 A capacity cannot use this substitute without circuit redesign.

Q: Are both components RoHS compliant?

A: Yes, both the ELMP04041 and 282843-4 are RoHS compliant, meeting environmental regulatory requirements.

Q: What wire gauges are compatible with each terminal block?

A: The ELMP04041 accommodates 8-18 AWG wire. The 282843-4 accommodates 12-30 AWG wire. Wire gauge selection must fall within the acceptable range for the chosen component.
