ELFH19180 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The ELFH19180 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 shrouded 4-side design provides mechanical protection and guided mating. Substitute parts are identified to address inventory availability, lead time requirements, or specific application constraints while maintaining functional compatibility within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH19180 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 19 positions at 0.197" (5.00mm) spacing (non-negotiable for PCB footprint compatibility)
• Connector Type & Orientation: Header with male pins, shrouded 4-side design, vertical orientation
• Mounting Method: Through-hole solder termination
• Electrical Ratings: Voltage rating of 300 V (UL) and current capacity of 12 A minimum (UL)
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance status

The Phoenix Contact 1755671 meets all substitution criteria within these parameters. Differences in color, contact tail length, and insulation height do not affect functional interchangeability for standard PCB mounting applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH19180 and 1755671 are active products with equivalent functional specifications for 19-position, 5.00mm pitch terminal block header applications. Selection between these parts should be based on:

ELFH19180 (Amphenol PCD): Select when the 15 A UL current rating is required, or when the specified operating temperature range of -40°C to 105°C is a design requirement. RoHS compliance is confirmed.

1755671 (Phoenix Contact): Select when inventory availability or lead time is the primary constraint. This part meets the 12 A UL current requirement and 300 V UL voltage specification. ROHS3 compliance status provides extended regulatory coverage. The defined contact tail length (3.90mm) and insulation height (12.00mm) may be advantageous for specific PCB layout requirements.

Both parts carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755671 be used as a direct replacement for the ELFH19180 on existing PCBs?

A: Yes, within the constraints of the application's current requirements. Both parts share identical pitch (5.00mm), position count (19), orientation (vertical), and mounting method (through-hole solder). The 1755671 supports 12 A at 300 V (UL), which is lower than the ELFH19180's 15 A rating. Verify that your application does not exceed 12 A per contact before substitution.

Q: What is the significance of the different colors (black vs. green)?

A: Color is a cosmetic and identification feature only. It does not affect electrical performance or mechanical compatibility. The black housing of the ELFH19180 and green housing of the 1755671 are manufacturer-specific design choices and do not impact substitutability.

Q: Are the contact tail length and insulation height differences important for PCB compatibility?

A: These dimensions affect solder joint formation and PCB clearance. The 1755671 specifies a contact tail length of 3.90mm and insulation height of 12.00mm. If your PCB design was validated with the ELFH19180 (dimensions not specified), physical verification of the 1755671's fit is recommended before high-volume production transition.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts are UL94 V-0 rated and RoHS compliant (ELFH19180 is RoHS Compliant; 1755671 is ROHS3 Compliant). Both carry MSL 1 (Unlimited) moisture sensitivity classification and share identical ECCN (EAR99) and HTSUS (8536.69.4040) codes, confirming regulatory equivalence.

Q: What is the current inventory status for each part?

A: ELFH19180 has 795 pieces in stock (Amphenol PCD, Tray packaging). 1755671 has 1150 pieces in stock (Phoenix Contact, Bulk packaging). Packaging format differences may affect procurement and handling procedures.
