Phoenix Contact 1704547 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704547 is an 8-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 1704547 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this terminal block header.

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704547 is determined by strict alignment with the following core parameters:

Position Count & Pitch: 8 positions at 0.197" (5.00mm) spacing (non-negotiable for PCB compatibility)
Orientation & Mounting: Vertical through-hole configuration
Electrical Performance: Current and voltage ratings must meet or exceed IEC/UL specifications
Termination Method: Solder termination required
Material & Compliance: UL94 V-0 flammability rating and RoHS compliance

The TE Connectivity AMP Connectors 282822-8 qualifies as a substitute based on matching position count, pitch, orientation, mounting type, termination style, and compliance certifications. Differences in shroud design (partial vs. 2-side shrouded) and housing material composition do not preclude substitution when electrical and mechanical interfaces remain compatible.

Engineering Selection Recommendations

The TE Connectivity 282822-8 is the qualified substitute for the obsolete Phoenix Contact 1704547. Selection rationale is based on the following engineering criteria:

Compliance & Availability: The 282822-8 maintains active product status with confirmed inventory availability (857 pcs), whereas the 1704547 is obsolete. Both components meet UL94 V-0 flammability requirements and RoHS compliance standards, ensuring regulatory alignment for new designs and legacy system support.

Electrical Performance: The 282822-8 provides superior current handling at 15A (UL) compared to the 1704547 at 10A (UL), while maintaining identical 300V (UL) voltage rating. This performance margin ensures safe operation in applications originally specified for the 1704547.

Mechanical Compatibility: Both components share identical pitch (0.197" / 5.00mm), position count (8), contact tail length (0.138" / 4.60mm), and through-hole solder termination. The 282822-8 insulation height of 0.472" (12.00mm) versus 0.441" (11.20mm) for the 1704547 represents a minor dimensional variance that does not compromise PCB layout compatibility in standard applications.

Material & Contact Specifications: Both use tin-plated contacts and polyamide housing with UL94 V-0 rating. The 282822-8 specifies PA66 (Nylon 6/6) versus the 1704547's PA (Nylon), representing equivalent material performance for this application class.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 282822-8 directly replace the Phoenix Contact 1704547 on existing PCBs?

A: Yes. Both components share identical pitch (5.00mm), position count (8), contact tail length (4.60mm), and solder termination specifications. The 0.031" (0.80mm) difference in insulation height does not affect PCB footprint compatibility for standard through-hole designs.

Q: What is the significance of the shroud design difference (partial vs. 2-side shrouded)?

A: The 282822-8 features 2-side shrouding compared to the 1704547's partial shroud. This provides enhanced mechanical protection and improved mating alignment. The shroud design does not affect electrical performance or solder pad compatibility.

Q: Are there any compliance or certification differences between these parts?

A: Both components are UL94 V-0 rated and RoHS compliant. The 282822-8 carries ROHS3 certification, representing the current RoHS standard, while the 1704547 is RoHS Compliant. Both meet MSL 1 (Unlimited) moisture sensitivity requirements.

Q: Does the 282822-8 meet the electrical specifications of the 1704547?

A: Yes. The 282822-8 exceeds the 1704547 specifications: 15A (UL) versus 10A (UL) current rating, and 300V (UL) matching voltage rating. The 282822-8 does not provide IEC current rating data; applications requiring IEC 14.6A specification should verify UL 15A equivalence with system requirements.

Q: What is the inventory status for these components?

A: The 1704547 is obsolete with no active inventory. The 282822-8 is active with 857 pcs in stock, ensuring availability for immediate procurement and production support.
