ELFH09190 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH09190 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 signal and power distribution in industrial and commercial applications. The need to identify equivalent and substitute parts arises from inventory availability, lead time considerations, and supply chain optimization across different manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH09190 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must have 9 positions with 0.197" (5.00mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Header Configuration: Vertical orientation with male pins and 2-side shrouding is mandatory for form-factor compatibility.
• Mounting & Termination: Through-hole solder termination is required for direct PCB integration.
• Electrical Ratings: Voltage rating of 300 V (UL) and current capacity of 12 A or greater (UL) satisfy the electrical requirements of the main part.
• Environmental & Compliance: UL94 V-0 flammability rating and MSL 1 classification ensure equivalent safety and moisture handling characteristics.
• Contact Finish: Tin plating on contact surfaces provides equivalent corrosion resistance and solderability.

The Phoenix Contact 1753576 meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

The Phoenix Contact 1753576 is a qualified substitute for the ELFH09190 based on the following engineering criteria:

• Electrical Equivalence: Both components meet 300 V UL voltage rating and 12 A UL current capacity, satisfying circuit protection and signal integrity requirements.
• Mechanical Compatibility: Identical 9-position, 5.00mm pitch configuration with vertical through-hole mounting ensures direct PCB footprint compatibility without layout modifications.
• Compliance Status: Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification, meeting equivalent safety and environmental standards. The substitute part holds ROHS3 compliance, exceeding the main part's RoHS compliance requirement.
• Physical Dimensions: Contact tail length and insulation height measurements are equivalent within standard manufacturing tolerances, ensuring proper mating with corresponding receptacle connectors.
• Product Status: Both components are active products with confirmed inventory availability, supporting uninterrupted supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753576 be used as a direct replacement for the ELFH09190 without PCB modifications?

A: Yes. Both components share identical position count (9), pitch spacing (5.00mm), orientation (vertical), and mounting type (through-hole solder). Physical dimensions are equivalent within standard tolerances, allowing direct substitution without PCB layout changes.

Q: What is the current capacity difference between these parts, and does it affect circuit design?

A: The ELFH09190 is rated for 15 A (UL), while the 1753576 is rated for 12 A (UL). If your circuit operates at or below 12 A, both parts are functionally equivalent. If your design requires current capacity above 12 A, the ELFH09190 must be used.

Q: Are there differences in housing material between these terminal blocks?

A: The ELFH09190 uses Polyamide (PA46), Nylon 4/6 housing. The 1753576 uses Polyamide (PA), Nylon housing. Both materials provide equivalent UL94 V-0 flammability performance and mechanical durability for this application class.

Q: Do both parts have the same environmental operating temperature range?

A: The ELFH09190 specifies -40°C to 105°C operating temperature. The 1753576 does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance across the full -40°C to 105°C range, the ELFH09190 should be specified.

Q: What packaging differences exist between these parts?

A: The ELFH09190 is supplied in Tray packaging, while the 1753576 is supplied in Bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH09190 is RoHS Compliant, and the 1753576 is ROHS3 Compliant. Both meet RoHS requirements for hazardous substance restrictions.
