ELFH07150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH07150 is a 7-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is classified as an active product and serves as a connector interface for wire termination in industrial and electronic applications. The need for equivalent and substitute parts arises from inventory availability, lead time considerations, and application-specific requirements across different manufacturing sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH07150 is determined by the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 7 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Orientation & Mounting: Vertical through-hole mounting is required for direct replacement in existing designs.
• Termination Method: Solder termination is mandatory for compatibility with standard PCB assembly processes.
• Electrical Ratings: Voltage rating of 300 V (UL) is a minimum requirement. Current ratings must meet or exceed application demands.
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating ensure regulatory and safety alignment.

The substitute part 1753534 (Phoenix Contact COMBICON MSTBV series) meets these core substitution criteria, though with variations in shroud configuration, housing material, and current rating specifications.

Parameter Comparison

Engineering Selection Recommendations

ELFH07150 (Amphenol PCD) is the primary specification component with active product status, 4-side shrouding, and a 15 A current rating. This part is suitable for applications requiring maximum electrical capacity and full shroud protection.

1753534 (Phoenix Contact) qualifies as a functional substitute with the following considerations:

• Maintains identical pitch, position count, and vertical through-hole mounting configuration.
• Meets the same 300 V UL voltage requirement and UL94 V-0 flammability standard.
• Current rating is reduced to 12 A, making it suitable for applications with lower current demands.
• Features 2-side shrouding instead of 4-side, affecting mechanical protection and EMI shielding characteristics.
• Housing material differs (Polyamide/Nylon vs. Polybutylene Terephthalate), with implications for thermal and chemical resistance.
• ROHS3 compliance exceeds RoHS Compliant status, ensuring broader regulatory alignment.

Selection between these parts should be based on current requirements, shroud configuration needs, and material compatibility with the target application environment.

Frequently Asked Questions (FAQ)

Q: Can 1753534 be used as a direct replacement for ELFH07150?

A: Functional substitution is possible when application current requirements do not exceed 12 A and 2-side shrouding is acceptable. The identical pitch, position count, and vertical through-hole mounting ensure mechanical compatibility with existing PCB layouts and mating connectors.

Q: What is the significance of shroud configuration differences?

A: The ELFH07150 provides 4-side shrouding, offering enhanced mechanical protection and improved EMI shielding. The 1753534 features 2-side shrouding, reducing overall component height and material usage while maintaining basic contact protection. Selection depends on application-specific shielding and space constraints.

Q: Are there voltage or compliance concerns with substitution?

A: Both parts maintain 300 V UL voltage rating and UL94 V-0 flammability compliance. The 1753534 carries ROHS3 compliance, which is more stringent than standard RoHS Compliant status, ensuring compatibility with current and future regulatory requirements.

Q: How do housing materials affect part selection?

A: ELFH07150 uses Polybutylene Terephthalate (PBT), offering superior thermal stability and chemical resistance. The 1753534 uses Polyamide (PA/Nylon), which provides adequate performance in standard environments but may have different thermal and chemical compatibility profiles. Material selection should align with operating temperature ranges and exposure conditions.

Q: What packaging considerations apply to these parts?

A: ELFH07150 is supplied in Tray packaging with 1052 pieces in stock. The 1753534 is supplied in Bulk packaging with 2750 pieces available. Packaging format may affect handling, storage, and integration into assembly workflows.
