Phoenix Contact 1704482 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704482 is a 4-position terminal block header with male pins and partial shroud, designed for 0.197" (5.00mm) pitch vertical through-hole applications. This component operates at 14.6A (IEC) / 10A (UL) and 400V (IEC) / 300V (UL), featuring tin-plated contacts and polyamide housing with UL94 V-0 flammability rating.

The product is currently obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this connector type.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704482 is determined by the following critical parameters:

Position Count & Pitch: Must be 4 positions at 0.197" (5.00mm) spacing
Orientation & Mounting: Vertical through-hole configuration required
Electrical Performance: Current and voltage ratings must meet or exceed IEC 14.6A / 400V or UL 10A / 300V specifications
Termination & Contact: Solder termination with tin-plated contacts
Housing & Compliance: Polyamide construction with UL94 V-0 flammability rating and RoHS compliance

The TE Connectivity AMP Connectors 282822-4 meets these core substitution criteria. While it features a shrouded (2-side) design versus the partial shroud of the original part, the electrical, mechanical, and compliance parameters align with the functional requirements of the 1704482.

Engineering Selection Recommendations

The TE Connectivity 282822-4 is a suitable substitute for the obsolete Phoenix Contact 1704482 based on the following engineering criteria:

Electrical Compatibility: The 282822-4 exceeds the current rating of the original part (15A UL versus 10A UL) while maintaining the same voltage specification (300V UL). The IEC current rating for the 1704482 (14.6A) is within the performance envelope of the substitute.

Mechanical Compatibility: Both parts share identical pitch (5.00mm), orientation (vertical), mounting type (through-hole), and contact tail length (4.60mm), ensuring PCB footprint compatibility.

Compliance & Reliability: Both components carry UL94 V-0 flammability certification and RoHS compliance status. The 282822-4 is an active product with current manufacturing support, addressing supply chain continuity for the obsolete 1704482.

Design Consideration: The primary design difference is the shroud configuration. The 282822-4 features 2-side shrouding compared to the partial shroud of the original part. This enhanced shrouding provides improved mechanical protection and may require verification of clearance in space-constrained PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 282822-4 directly replace the Phoenix Contact 1704482 on existing PCBs?

A: Yes, from an electrical and mechanical standpoint. Both parts share the same 5.00mm pitch, vertical orientation, through-hole mounting, and 4.60mm contact tail length. PCB footprints are compatible. However, the enhanced 2-side shrouding of the 282822-4 may require clearance verification in confined spaces.

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

A: The primary differences are shroud design (partial versus 2-side), housing material specification (PA versus PA66), and product status (obsolete versus active). The 282822-4 also provides higher current capacity (15A UL) and includes operating temperature specification (-40°C to 110°C).

Q: Are both parts RoHS compliant?

A: Yes. The Phoenix Contact 1704482 is ROHS3 Compliant, and the TE Connectivity 282822-4 is RoHS Compliant. Both meet current environmental compliance requirements.

Q: What is the significance of the shroud type difference?

A: The partial shroud on the 1704482 provides minimal side protection, while the 2-side shroud on the 282822-4 offers enhanced mechanical protection and reduced risk of accidental contact. This may affect board layout and component spacing considerations.

Q: Is the TE Connectivity part available in production quantities?

A: Yes. The 282822-4 is an active product with 2400 pieces in stock, providing reliable supply availability compared to the obsolete 1704482.
