ELFH03140 Equivalent & Substitute Parts Reference

Part Overview

The Amphenol PCD ELFH03140 is a terminal block header from the ELFH series, featuring a 3-position, right angle, through-hole configuration with a 5.00mm pitch and shrouded (2 side) male pins. It is rated for 15A/300V (UL) and operates from -40°C to 105°C. This component is RoHS compliant and active, suitable for PCB connection applications. Identifying equivalent or substitute terminal blocks is necessary in cases of inventory constraints, supply chain optimization, or to ensure consistent availability of functionally compatible components within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitute terminal block headers are selected strictly on the basis of matching or closely corresponding electrical and mechanical parameters: type (header, male pins, shrouded), number of positions, number of levels, pitch, orientation, termination style, mounting type, voltage and current ratings, color, operating temperature, contact finish, material ratings, contact and housing materials, dimensions, RoHS compliance, and active part status. Only parts aligning with these parameters are included as valid substitutes.

Key parameters governing substitution:

• Type
• Number of Positions
• Pitch
• Orientation
• Termination Style
• Mounting Type
• Electrical Ratings (Current/Voltage)
• Flammability Rating
• Material Composition
• RoHS/Compliance Status
• Active Availability

Parameter Comparison

Engineering Selection Recommendations

Both ELFH03140 (Amphenol PCD) and 0395320003 (Molex) terminal block headers are active, RoHS compliant, and maintain equivalent electrical ratings (15A/300V). Both parts carry a UL94 V-0 flammability rating and meet the stated mechanical and thermal requirements. Selection can be based solely on inventory status, specific RoHS certification version, or compliance as both are MSL 1 (unlimited) and fulfill the provided compliance designations.

Frequently Asked Questions (FAQ)

Q1: What is the primary substitution criterion for terminal block headers?
A1: Substitution requires matching or closely corresponding parameters including type, number of positions, pitch, orientation, termination style, mounting type, electrical ratings, flammability rating, material composition, and compliance status.

Q2: Can a different housing material affect compatibility?
A2: Housing materials listed (Polyamide (PA46)/Nylon 4/6 vs. Polyamide (PA66)/Nylon 6/6) are both UL94 V-0 rated, ensuring compliance with specified flammability standards.

Q3: Is a small difference in pitch or insulation height acceptable in this context?
A3: Only parts with parameters within the range provided (pitch, insulation height) are included for substitution. Specific values are listed in the parameter comparison for engineering review.

Q4: Are all substitute parts also through-hole and right angle?
A4: All listed substitute models are through-hole and 90° right angle, matching the main part’s mechanical configuration.

Q5: How does RoHS compliance affect part selection?
A5: Both main and substitute parts are RoHS compliant, maintaining required environmental compliance for regulated markets.

Q6: Can different packaging types (tray vs. bulk) impact substitutability?
A6: Packaging type does not affect electrical or mechanical compatibility and is not a basis for exclusion in this reference.

Q7: Are current and voltage ratings identical between main and substitute parts?
A7: All compared parts state the same UL current and voltage ratings: 15A and 300V.
