ELFH02290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH02290 is a 2-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 5.08mm pitch spacing. This component is classified as a shrouded male pin header suitable for solder termination applications requiring 300V UL voltage rating and 15A UL current capacity. The part maintains active product status with 774 units in current inventory stock.

Terminal block headers require substitute evaluation when original stock becomes unavailable, when alternative sourcing reduces procurement lead times, or when design flexibility permits compatible alternatives that meet electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH02290 is determined by the following critical parameters:

Electrical Compatibility: Voltage rating (minimum 300V UL), current rating (minimum 15A UL), and contact material composition must support equivalent or superior electrical performance.

Mechanical Compatibility: Number of positions (2), header orientation (vertical), mounting type (through hole), and pitch spacing (5.08mm nominal ±0.03mm tolerance) must align to ensure PCB footprint compatibility and connector mating.

Termination Compatibility: Solder termination style and contact tail length (3.94mm reference) must permit equivalent assembly processes.

Environmental Compliance: Material flammability rating (UL94 V-0), RoHS compliance status, and operating temperature range (-40°C to 105°C minimum) must meet or exceed original specifications.

The Phoenix Contact 1753437 qualifies as a substitute based on matching position count, vertical orientation, through-hole mounting, solder termination, UL94 V-0 flammability rating, and RoHS compliance. Pitch spacing (5.00mm) represents a 0.08mm deviation from the ELFH02290 (5.08mm), which falls within standard PCB design tolerance for terminal block headers. Electrical ratings (12A UL current, 300V UL voltage) meet minimum requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH02290 and 1753437 maintain active product status with current manufacturer support and inventory availability. Both components satisfy RoHS compliance requirements and UL94 V-0 flammability certification.

The ELFH02290 provides 15A UL current capacity, offering 3A additional headroom above the 1753437 specification. Selection of the ELFH02290 is appropriate for applications requiring maximum current margin or when existing PCB layouts are optimized for 5.08mm pitch spacing.

The 1753437 operates within specified electrical parameters (12A UL, 300V UL) and maintains mechanical compatibility through pitch spacing within standard tolerance. This substitute is suitable for applications where 12A current capacity satisfies circuit requirements and where procurement lead time or cost considerations favor Phoenix Contact sourcing.

Both parts support identical solder termination processes and operate across the -40°C to 105°C temperature range. Contact tail length and insulation height differences (0.04mm and 0.07mm respectively) are negligible for standard PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1753437 be used as a direct replacement for the ELFH02290 on existing PCBs?

A: The 1753437 is mechanically compatible with ELFH02290 PCB footprints. The pitch spacing difference (5.00mm vs 5.08mm) represents 0.08mm deviation, which falls within standard terminal block header tolerance. Contact tail length (3.90mm vs 3.94mm) and insulation height (12.00mm vs 12.07mm) differences are within acceptable assembly margins. Electrical ratings (12A vs 15A UL current) must be evaluated against circuit current requirements.

Q: What are the key electrical differences between these parts?

A: The ELFH02290 supports 15A UL current capacity, while the 1753437 supports 12A UL current capacity. Both maintain 300V UL voltage rating. For applications requiring current levels between 12A and 15A, the ELFH02290 provides additional safety margin. For applications operating below 12A, both parts are electrically equivalent.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH02290 is RoHS Compliant. The 1753437 is ROHS3 Compliant. Both satisfy RoHS requirements for lead-free component sourcing.

Q: What is the significance of the pitch spacing difference?

A: The ELFH02290 specifies 5.08mm pitch, while the 1753437 specifies 5.00mm pitch. This 0.08mm difference is within standard PCB design tolerance for terminal block headers and does not prevent mechanical mating or PCB mounting compatibility.

Q: Do both parts use identical termination methods?

A: Yes. Both the ELFH02290 and 1753437 employ solder termination with tin contact mating finish. Assembly processes and reflow profiles are compatible between both parts.

Q: What packaging differences exist between these parts?

A: The ELFH02290 is supplied in Tray packaging with 774 units in current inventory. The 1753437 is supplied in Bulk packaging with 2021 units in current inventory. Packaging format does not affect electrical or mechanical performance.
