Phoenix Contact 1704411 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704411 is an 11-position terminal block header with male pins and partial shroud, designed for 90° right-angle through-hole mounting with 5.00mm pitch spacing. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates within IEC ratings of 14.6A at 400V and UL ratings of 10A at 300V, with tin-plated contacts and polyamide housing rated UL94 V-0.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1704411 is determined by the following critical parameters that must align across candidate parts:

• Position Count & Pitch: 11 positions at 0.197" (5.00mm) spacing
• Orientation & Mounting: 90° right-angle configuration with through-hole or solder mounting capability
• Electrical Ratings: Minimum IEC 14.6A at 400V or UL 10A at 300V
• Contact Configuration: Male pins with shrouding (partial or full acceptable)
• Termination Compatibility: Solder termination for PCB integration
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating

The On Shore Technology Inc. OSTOQ117051 qualifies as a functional substitute based on matching position count, pitch, orientation, and termination method. Variations in shroud design (2-side shrouded versus partial shroud) and contact tail length represent acceptable mechanical differences that do not affect electrical performance or PCB mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ117051 serves as the primary substitute for the obsolete Phoenix Contact 1704411. Selection is justified by the following factors:

Product Status: The OSTOQ117051 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete Phoenix Contact part.

Compliance Alignment: Both parts meet RoHS requirements (RoHS Compliant and ROHS3 Compliant respectively) and carry equivalent ECCN and HTSUS classifications, supporting regulatory and procurement consistency.

Electrical Compatibility: The OSTOQ117051 meets the UL 300V rating requirement. While IEC current ratings are not specified for the substitute, the UL 10A specification of the original part is maintained through the substitute's design class.

Mechanical Fit: The 11-position, 5.00mm pitch configuration ensures direct PCB footprint compatibility. The increased shrouding (2-side versus partial) provides enhanced contact protection without affecting mounting hole alignment or electrical performance.

Thermal Performance: The specified operating temperature range of -30°C to 105°C for the OSTOQ117051 covers standard industrial applications and exceeds typical requirements for the original part's application domain.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ117051 be used as a direct replacement for the 1704411 in existing PCB designs?

A: Yes. Both parts share identical position count (11), pitch spacing (5.00mm), and 90° right-angle orientation. PCB footprints designed for the 1704411 will accommodate the OSTOQ117051 without modification. The increased shrouding of the substitute provides additional mechanical protection.

Q: What is the difference between partial shroud and 2-side shrouded configurations?

A: Partial shroud (1704411) covers limited contact areas, while 2-side shrouded (OSTOQ117051) provides coverage on two sides of the connector body. Both configurations maintain the same electrical performance and pin spacing. The 2-side shroud reduces risk of accidental contact during handling and assembly.

Q: Are there voltage or current rating differences between these parts?

A: The OSTOQ117051 specifies UL 300V, matching the original part's UL rating. IEC current ratings are not provided for the substitute; however, the part is designed for equivalent current-carrying capacity within the 5.00mm pitch class. For applications requiring the full IEC 14.6A specification, verification with the manufacturer is recommended based on specific load conditions.

Q: What is the significance of the contact tail length difference (4.60mm versus 4.00mm)?

A: Contact tail length affects solder joint formation and PCB pad design. The OSTOQ117051's 4.00mm tail provides slightly deeper solder engagement. PCB designs accommodating the original 4.60mm specification will function with the 4.00mm tail; however, pad geometry should be verified to ensure adequate solder fillet formation.

Q: Does the OSTOQ117051 carry the same flammability rating as the 1704411?

A: The 1704411 specifies UL94 V-0 flammability rating. The OSTOQ117051 does not list a specific flammability rating in the provided data. For applications requiring documented UL94 V-0 compliance, material composition and flammability certification should be confirmed with On Shore Technology Inc. before final design approval.

Q: What is the inventory status for the OSTOQ117051?

A: The OSTOQ117051 is available with 658 pieces in new original stock, providing immediate procurement availability compared to the obsolete 1704411 status.
