ELFH09290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH09290 is a 9-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This component is actively produced and stocked at 1065 units. Terminal block headers serve as connection interfaces in industrial control systems, power distribution, and signal routing applications where reliable solder-terminated connections are required. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH09290 is determined by the following critical parameters:

Position Count: Both the main part and substitute must provide 9 positions to maintain circuit connectivity and PCB layout compatibility.

Pitch Specification: The ELFH09290 operates at 0.200" (5.08mm) pitch. The substitute part 1753576 operates at 0.197" (5.00mm) pitch, representing a 0.03mm variance. This minor pitch difference falls within acceptable mechanical tolerance for through-hole mounting applications where PCB pad spacing can accommodate both specifications.

Header Type and Orientation: Both parts are vertical-mount, male-pin headers with 2-side shrouding, ensuring identical mechanical interface and mating characteristics.

Termination and Mounting: Both parts use solder termination and through-hole mounting, maintaining identical assembly processes and PCB integration methods.

Electrical Ratings: The ELFH09290 is rated at 15A (UL) and 300V (UL). The substitute 1753576 is rated at 12A (UL) and 300V (UL), with additional IEC ratings of 12A and 400V. The substitute's lower UL current rating (12A vs 15A) requires circuit validation to confirm adequacy for the intended application.

Compliance and Material: Both parts meet UL94 V-0 flammability requirements and maintain RoHS compliance status, ensuring regulatory alignment for industrial and consumer applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ELFH09290): Recommended for applications requiring the full 15A UL current rating. Active product status and established supply chain (1065 units in stock) support consistent availability. RoHS compliance meets standard industrial and consumer regulatory requirements.

Substitute Part (1753576): Applicable in circuits where the 12A UL current rating satisfies design requirements. ROHS3 compliance indicates enhanced environmental and substance restriction adherence. Phoenix Contact manufacturing provides alternative supply chain access. The 0.03mm pitch variance and 0.04mm insulation height difference are within mechanical tolerance for standard PCB through-hole applications.

Selection Criteria: Choose the substitute part only when circuit current requirements do not exceed 12A and when PCB pad spacing accommodates the 5.00mm pitch specification. Both parts maintain identical voltage ratings (300V UL) and flammability compliance (UL94 V-0), supporting direct substitution in applications meeting the current constraint.

Frequently Asked Questions (FAQ)

Q: Can the 1753576 substitute directly for the ELFH09290 in all applications?

A: Direct substitution is valid only when the circuit current requirement does not exceed 12A. The ELFH09290 supports 15A, while the 1753576 is rated at 12A. Voltage ratings (300V) and flammability compliance (UL94 V-0) are identical, supporting substitution in current-compliant designs.

Q: What is the significance of the pitch difference between 5.08mm and 5.00mm?

A: The 0.03mm variance represents a 0.6% difference. Standard PCB through-hole pad tolerances accommodate both specifications. However, PCB layout must be verified to confirm pad spacing compatibility with the 5.00mm pitch before component placement.

Q: Are both parts suitable for the same operating temperature range?

A: The ELFH09290 specifies -40°C to 105°C operating temperature. The 1753576 does not provide an operating temperature specification in the available data. Thermal performance validation is required if the substitute is used in temperature-critical applications.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. The ELFH09290 is RoHS Compliant. The 1753576 is ROHS3 Compliant, indicating compliance with the most current RoHS directive revision. Both parts meet UL94 V-0 flammability requirements for industrial applications.

Q: What packaging differences exist between these parts?

A: The ELFH09290 is supplied in Tray packaging (1065 units in stock). The 1753576 is supplied in Bulk packaging (1550 units in stock). Packaging format may affect procurement, storage, and assembly handling procedures.
