ELFH19290 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH19290 is a 19-position terminal block header manufactured by Amphenol PCD, designed for vertical through-hole mounting with 0.200" (5.08mm) pitch spacing. This component is classified as an active product and serves as a connector interface for wire termination in industrial and electronic applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH19290 is determined by the following critical parameters:

• Position Count: Must equal 19 positions to maintain PCB layout compatibility
• Pitch Specification: Primary pitch is 0.200" (5.08mm); minor pitch variations (0.197" / 5.00mm) fall within acceptable tolerance for mechanical fit in standard 5mm-class connector footprints
• Orientation: Must be vertical through-hole configuration
• Termination Method: Solder termination required
• Electrical Ratings: Substitute must meet or exceed UL voltage (300 V minimum) and current (12 A minimum) specifications
• Flammability Compliance: UL94 V-0 rating required for safety-critical applications
• RoHS Compliance: Substitute must maintain RoHS or ROHS3 compliance status

The Phoenix Contact 1755671 qualifies as a substitute based on matching position count, vertical orientation, solder termination, compatible pitch tolerance, and equivalent electrical and safety certifications.

Parameter Comparison

Engineering Selection Recommendations

ELFH19290 (Primary Selection)

Use the ELFH19290 when the application requires the full 15 A UL current rating and the specified operating temperature range of -40°C to 105°C. This part maintains active product status and is RoHS compliant. The 2-side shroud configuration provides standard EMI shielding for most industrial applications.

1755671 (Substitute Selection)

The Phoenix Contact 1755671 is suitable as a substitute when:

• Application current requirement does not exceed 12 A (UL rating)
• PCB layout can accommodate the 0.197" (5.00mm) pitch within design tolerance
• The 4-side shroud configuration is compatible with the mechanical envelope
• ROHS3 compliance status is acceptable for the application
• IEC electrical ratings (12 A / 400 V) meet or exceed application requirements

Both parts carry UL94 V-0 flammability certification, EAR99 export classification, and identical HTSUS tariff codes, confirming regulatory and compliance equivalence for standard industrial use.

Frequently Asked Questions (FAQ)

Q: Can the 1755671 be used as a direct replacement for the ELFH19290 in all applications?

A: The 1755671 is compatible for applications where the current requirement does not exceed 12 A. The ELFH19290 supports 15 A, so applications requiring the full 15 A rating must use the primary part. Pitch tolerance (5.08mm vs. 5.00mm) is acceptable for standard PCB footprints designed for 5mm-class connectors.

Q: What is the significance of the shroud configuration difference (2-side vs. 4-side)?

A: The ELFH19290 features 2-side shrouding, while the 1755671 has 4-side shrouding. This affects the mechanical envelope and EMI shielding characteristics. Verify that the 4-side shroud does not interfere with adjacent PCB components or enclosure constraints before substitution.

Q: Are both parts suitable for high-temperature applications?

A: The ELFH19290 specifies an operating temperature range of -40°C to 105°C. The 1755671 does not provide an operating temperature specification in the available data. For applications requiring confirmed temperature performance beyond standard industrial ranges, the ELFH19290 is the specified choice.

Q: Do both parts meet current regulatory compliance standards?

A: Yes. The ELFH19290 is RoHS compliant, and the 1755671 is ROHS3 compliant. Both carry UL94 V-0 flammability certification and are classified under identical HTSUS tariff code 8536.69.4040. Both have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the pitch tolerance consideration for substitution?

A: The ELFH19290 specifies 0.200" (5.08mm) pitch, while the 1755671 specifies 0.197" (5.00mm) pitch. This 0.08mm difference is within acceptable tolerance for standard 5mm-class connector footprints. However, verify PCB layout constraints and connector mating specifications before final selection.

Q: Are there any voltage or current derating considerations?

A: The ELFH19290 is rated 15 A / 300 V (UL). The 1755671 is rated 12 A / 300 V (UL) and 12 A / 400 V (IEC). For applications requiring the full 15 A capacity, the ELFH19290 must be used. The 1755671 is suitable for applications up to 12 A.
