ELFH19190 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH19190 is a 19-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 2-side shrouding, solder termination, and operates within a temperature range of -40°C to 105°C. Equivalent and substitute parts are identified to provide procurement flexibility, inventory alternatives, and continuity of supply for applications requiring compatible 19-position vertical terminal block headers with matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELFH19190 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Number of positions: 19 (exact match required)
• Pitch spacing: 0.197" (5.00mm) (exact match required)
• Header orientation: Vertical (exact match required)
• Termination style: Solder (exact match required)
• Mounting type: Through hole (exact match required)
• Voltage rating: 300 V UL minimum (equal or greater)
• Current rating: 12 A minimum (equal or greater acceptable for derating applications)
• Material flammability: UL94 V-0 (equal or greater)
• RoHS compliance: Compliant status (equal or greater)

The Phoenix Contact 1755671 qualifies as a substitute part. While it features 4-side shrouding compared to the 2-side shrouding of the ELFH19190, both parts maintain identical position count, pitch, orientation, and termination methodology. The electrical ratings (300 V UL, 12 A UL) and compliance certifications (UL94 V-0, RoHS3) satisfy the minimum requirements for substitution in applications where the main part is unavailable.

Parameter Comparison

Engineering Selection Recommendations

The ELFH19190 is an active product with confirmed inventory availability (873 pcs) and full RoHS compliance certification. For applications requiring this specific part, direct procurement is recommended when supply is available.

The Phoenix Contact 1755671 serves as a qualified substitute when ELFH19190 availability is constrained. Selection of the substitute should be based on the following criteria:

• Current requirement does not exceed 12 A UL rating
• PCB layout accommodates 4-side shrouded housing (larger footprint than 2-side shrouding)
• Application environment tolerates unspecified operating temperature range or operates within -40°C to 105°C
• ROHS3 compliance status meets or exceeds project requirements

Both parts carry UL94 V-0 flammability certification and 300 V UL voltage rating, satisfying safety and electrical performance requirements for industrial terminal block applications. The mechanical dimensions (contact tail length and insulation height) are equivalent within standard manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755671 directly replace the ELFH19190 on existing PCBs?

A: Direct replacement is possible with PCB layout verification. The 4-side shrouding of the 1755671 results in a larger overall housing footprint compared to the 2-side shrouding of the ELFH19190. Contact tail length and insulation height differences are negligible (0.04mm and 0.07mm respectively), but board-level clearances and connector mating surfaces must be confirmed before assembly.

Q: What is the current rating difference between these parts?

A: The ELFH19190 is rated for 15 A UL, while the 1755671 is rated for 12 A UL. The 3 A difference is significant for high-current applications. The substitute part is suitable only for applications operating at or below 12 A. Current derating calculations should be performed if thermal management is a design consideration.

Q: Are both parts RoHS compliant?

A: Yes. The ELFH19190 carries RoHS Compliant certification, and the 1755671 carries ROHS3 Compliant certification. ROHS3 represents the updated RoHS Directive 2011/65/EU compliance standard. Both certifications satisfy RoHS requirements for electronic component procurement.

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

A: Shrouding refers to the protective housing surrounding the terminal block pins. 2-side shrouding provides protection on two opposing sides, while 4-side shrouding provides protection on all four sides. 4-side shrouding offers enhanced mechanical protection and reduced risk of accidental contact, but requires additional PCB space and may affect connector accessibility during assembly and maintenance.

Q: Are the voltage and pitch specifications identical?

A: Yes. Both parts operate at 300 V UL and feature 0.197" (5.00mm) pitch spacing. These critical electrical and mechanical parameters are exact matches, ensuring compatibility in applications designed for 19-position, 5.00mm pitch terminal block headers.

Q: What packaging differences exist between these parts?

A: The ELFH19190 is supplied in Tray packaging, while the 1755671 is supplied in Bulk packaging. Packaging format does not affect electrical or mechanical performance but may influence inventory management, handling procedures, and cost per unit.
