ELFH09150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH09150 is a 9-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 electrical termination in industrial and commercial applications. The part features male pins with 4-side shrouding, solder termination, and operates within a temperature range of -40°C to 105°C. Alternative equivalent parts may be required due to inventory availability, lead time considerations, or specific application requirements related to shrouding configuration or housing material specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH09150 is determined by the following critical parameters:

• Number of Positions and Pitch: Both the main part and substitute must maintain 9 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Orientation and Mounting Type: Vertical through-hole mounting is required to match the original application footprint.
• Termination Style: Solder termination is mandatory for compatibility with standard PCB assembly processes.
• Voltage and Current Ratings: Substitute parts must meet or exceed UL voltage (300 V) and current (15 A) specifications to ensure safe operation within the intended electrical environment.
• Shrouding Configuration: While the main part features 4-side shrouding, substitutes with reduced shrouding (2-side) may be acceptable depending on application-specific EMI/RFI requirements and mechanical clearance constraints.
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating are required for regulatory and safety adherence.

The substitute part 1753576 (Phoenix Contact COMBICON MSTBV series) meets the core substitution criteria of position count, pitch, orientation, and termination style, with the primary difference being 2-side shrouding instead of 4-side shrouding.

Parameter Comparison

Engineering Selection Recommendations

The ELFH09150 and 1753576 are functionally equivalent for applications requiring 9-position, 5.00mm pitch vertical terminal block headers with solder termination. Both parts maintain active product status and comply with UL94 V-0 flammability requirements and RoHS standards.

The primary distinction is the shrouding configuration: the ELFH09150 provides 4-side shrouding, while the 1753576 provides 2-side shrouding. This difference affects mechanical protection and EMI/RFI shielding characteristics. The 1753576 exhibits a lower UL current rating (12 A versus 15 A), which must be evaluated against specific application current requirements. Housing material differs between the parts (PBT versus PA/Nylon), which may influence thermal and chemical resistance properties in specialized environments.

Selection between these parts should be based on shrouding requirements, current load specifications, and housing material compatibility with the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can the 1753576 directly replace the ELFH09150 in existing designs?

A: Direct replacement is possible if the application does not require 4-side shrouding and operates at currents not exceeding 12 A. The identical pitch, position count, and vertical through-hole mounting ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors. However, the reduced shrouding and lower current rating must be evaluated against design specifications.

Q: What is the significance of the shrouding difference between 4-side and 2-side configurations?

A: 4-side shrouding provides enhanced mechanical protection and improved EMI/RFI containment by surrounding the pin array on all sides. 2-side shrouding provides reduced protection but may offer advantages in applications with space constraints or where full shrouding is not required. The choice depends on the specific application environment and electromagnetic compatibility requirements.

Q: Are there differences in housing material that affect performance?

A: The ELFH09150 uses Polybutylene Terephthalate (PBT), while the 1753576 uses Polyamide (PA) and Nylon. Both materials meet UL94 V-0 flammability standards. PBT generally offers superior dimensional stability and lower moisture absorption, while PA/Nylon provides good mechanical properties. Material selection should consider the operating environment, temperature exposure, and chemical compatibility requirements.

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

A: The ELFH09150 is rated for 15 A (UL), while the 1753576 is rated for 12 A (UL). For applications operating at currents between 12 A and 15 A, the ELFH09150 must be used. For applications operating below 12 A, both parts are suitable.

Q: Do both parts comply with RoHS requirements?

A: Yes. The ELFH09150 is RoHS Compliant, and the 1753576 is ROHS3 Compliant. Both meet current RoHS standards for hazardous substance restrictions.
