Phoenix Contact 1704576 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704576 is an 11-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 classified as 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 component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704576 is determined by the following critical parameters:

• Position Count & Pitch: Substitute parts must have 11 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.
• Orientation & Mounting: Vertical orientation with solder termination is required for through-hole PCB assembly compatibility.
• Electrical Ratings: Substitute parts must meet or exceed the voltage and current requirements (minimum 300V UL / 10A UL for direct substitution).
• Contact & Housing Materials: Tin-plated contacts and thermoplastic housing materials ensure equivalent electrical performance and environmental resistance.
• Compliance: RoHS compliance is mandatory for modern supply chains; REACH status and ECCN classification must align with regulatory requirements.

The On Shore Technology Inc. OSTOQ117050 qualifies as a functional equivalent based on these parameters, with the primary design difference being full shrouding (2-side) versus partial shrouding on the original part.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ117050 is an active-status substitute for the obsolete Phoenix Contact 1704576. Both components meet the same electrical specifications at the UL rating level (300V, 10A minimum) and share identical pitch, position count, and vertical orientation.

Key considerations for selection:

• Shroud Design: The OSTOQ117050 features 2-side shrouding compared to the partial shroud of the original part. This provides enhanced EMI shielding and mechanical protection but may require verification of PCB layout compatibility, particularly in confined spaces.
• Contact Tail Length: The OSTOQ117050 has a contact tail length of 0.157" (4.00mm) versus 0.138" (4.60mm) on the original part. This difference must be evaluated against PCB hole depth and solder joint requirements.
• Compliance Status: Both components are RoHS compliant. The OSTOQ117050 carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for new designs and production.
• Supply Availability: The OSTOQ117050 is in active production with 968 units in stock, ensuring long-term availability compared to the obsolete Phoenix Contact part.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ117050 be used as a direct drop-in replacement for the Phoenix Contact 1704576?

A: The OSTOQ117050 is electrically and mechanically compatible at the connector interface level (11 positions, 5.00mm pitch, vertical orientation, solder termination). However, the differences in shroud design, contact tail length (0.157" vs. 0.138"), and insulation height (0.157" vs. 0.441") require PCB layout verification before implementation. Physical fit testing is recommended for existing designs.

Q: What are the electrical compatibility limits between these two parts?

A: Both parts meet 300V UL and 10A UL ratings. The Phoenix Contact part specifies higher IEC ratings (400V, 14.6A), which are not matched by the OSTOQ117050. If your application requires IEC-level ratings, alternative substitutes should be evaluated.

Q: Are there any compliance or certification differences?

A: Both components are RoHS compliant. The OSTOQ117050 carries ROHS3 compliance and REACH Unaffected status, making it suitable for current regulatory environments. The Phoenix Contact part does not specify REACH status in the provided data.

Q: How do the shroud designs affect application suitability?

A: The partial shroud on the Phoenix Contact 1704576 provides minimal side protection, while the 2-side shroud on the OSTOQ117050 offers enhanced EMI shielding and mechanical protection. The increased shrouding may affect mating connector alignment or require design adjustments in space-constrained applications.

Q: What should be verified before switching to the OSTOQ117050?

A: Verify PCB hole depth compatibility with the 0.157" contact tail length, confirm shroud clearance in the assembly area, validate solder joint formation with the different tail geometry, and test mating connector engagement with the 2-side shroud design.
