ELFH05150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH05150 is a 5-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component features male pins with 4-side shrouding and is rated for 15A at 300V (UL). The part is currently active in production with 715 units in stock. Alternative equivalent parts may be required due to supply constraints, design revisions, or specific application requirements for different shrouding configurations or voltage/current ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH05150 is determined by the following critical parameters:

• Number of Positions and Pitch: Must be 5 positions at 0.197" (5.00mm) spacing to maintain PCB layout compatibility
• Header Orientation: Must be vertical through-hole configuration
• Termination Style: Must be solder-based for direct PCB mounting
• Shrouding Configuration: 4-side shrouding is the baseline; 2-side shrouding represents a functional alternative with reduced mechanical protection
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements (15A/300V UL minimum)
• Material Compliance: Housing and contact materials must maintain UL94 V-0 flammability rating and RoHS compliance
• Contact Finish: Tin plating ensures solderability and corrosion resistance

The Phoenix Contact 1753495 qualifies as a substitute based on matching position count, pitch, orientation, termination style, and electrical ratings. The primary difference is the 2-side shrouding versus 4-side shrouding on the original part.

Parameter Comparison

Engineering Selection Recommendations

ELFH05150 (Amphenol PCD) is the primary specification. This part is active in production with full RoHS compliance and provides 15A current capacity at 300V with 4-side shrouding for maximum mechanical protection and EMI shielding.

1753495 (Phoenix Contact) is a functional equivalent suitable for applications where the 12A current rating is sufficient and 2-side shrouding meets mechanical requirements. This part carries ROHS3 compliance and is available in higher inventory (1161 units). The reduced shrouding configuration may affect EMI performance in noise-sensitive applications.

Selection between these parts should be based on:

• Current requirement: If the application requires more than 12A, the ELFH05150 is mandatory
• Shrouding requirement: If 4-side shrouding is specified for EMI or mechanical protection, the ELFH05150 is required
• Supply availability: The 1753495 offers higher stock levels for immediate availability
• Compliance certification: Both parts meet UL94 V-0 and RoHS requirements; ROHS3 compliance on the 1753495 indicates updated regulatory alignment

Frequently Asked Questions (FAQ)

Q: Can the 1753495 be used as a direct replacement for the ELFH05150?

A: The 1753495 is functionally compatible for applications requiring 12A or less at 300V. The primary differences are the reduced shrouding (2-side vs. 4-side) and lower current rating. PCB layout compatibility is maintained due to identical pitch and position count. Verify that your application does not require the additional mechanical protection or EMI shielding provided by 4-side shrouding.

Q: What is the impact of 2-side versus 4-side shrouding?

A: 4-side shrouding on the ELFH05150 provides complete mechanical protection around the header and improved EMI containment. 2-side shrouding on the 1753495 reduces material usage and cost but offers less protection against accidental contact and reduced shielding effectiveness. Select based on application environment and EMI requirements.

Q: Are there any soldering or assembly differences between these parts?

A: Both parts use identical solder termination style and through-hole mounting. No assembly process changes are required. Verify PCB pad dimensions match the contact tail specifications if available.

Q: Do both parts meet the same compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant. The ELFH05150 carries standard RoHS compliance, while the 1753495 carries ROHS3 compliance, indicating alignment with the most current regulatory requirements. Both are suitable for regulated applications.

Q: What is the current rating difference, and when does it matter?

A: The ELFH05150 is rated for 15A (UL), while the 1753495 is rated for 12A (UL). If your application draws more than 12A per position, the ELFH05150 is required. For applications at or below 12A, the 1753495 is acceptable.
