Phoenix Contact 1704437 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1704437 is a 2-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 connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1704437 is determined by the following critical parameters:

Core Compatibility Requirements:

• Number of positions: 2
• Pitch: 0.197" (5.00mm)
• Header orientation: Vertical
• Contact mating finish: Tin
• Termination method: Solder-based
• Voltage rating: Minimum 300V (UL standard)
• RoHS compliance status

The On Shore Technology Inc. OSTOQ027050 qualifies as a substitute based on matching these core parameters. Both components share identical position count, pitch spacing, vertical orientation, and tin-plated contacts. Both meet RoHS compliance requirements and operate within compatible voltage specifications (300V UL rating). The primary design difference is the shroud configuration: the Phoenix Contact features partial shroud coverage, while the OSTOQ027050 provides 2-side shrouded design, which offers enhanced mechanical protection and contact isolation.

Parameter Comparison

Engineering Selection Recommendations

The On Shore Technology OSTOQ027050 is an active-status substitute for the obsolete Phoenix Contact 1704437. Both components meet RoHS compliance requirements and share identical electrical specifications for 2-position, 5.00mm pitch vertical terminal block header applications.

Selection between these components should be based on:

Mechanical Compatibility: The OSTOQ027050 features 2-side shrouding compared to the partial shroud design of the 1704437. This difference affects PCB layout clearances and mechanical mounting considerations. The contact tail length differs by 0.019" (0.50mm), which may impact solder joint formation and PCB trace routing.

Supply Chain Status: The OSTOQ027050 maintains active production status with documented inventory availability, whereas the 1704437 is obsolete. For new designs or ongoing production support, the OSTOQ027050 provides supply continuity.

Compliance Certification: Both components carry RoHS compliance certifications suitable for regulated applications. The OSTOQ027050 explicitly lists ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can the OSTOQ027050 directly replace the Phoenix Contact 1704437 in existing designs?

A: Direct replacement requires verification of PCB layout compatibility. The 2-side shroud design of the OSTOQ027050 occupies different physical space than the partial shroud 1704437. Contact tail length variation (0.138" vs. 0.157") may affect solder joint clearances. Electrical compatibility is confirmed for 2-position, 5.00mm pitch applications.

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

A: Both components operate at 300V (UL rating). The 1704437 specifies 14.6A (IEC) and 10A (UL), while the OSTOQ027050 does not provide current ratings in the available data. Verify current requirements against application specifications before selection.

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

A: The partial shroud on the 1704437 provides minimal contact isolation, while the 2-side shroud on the OSTOQ027050 offers enhanced mechanical protection and reduced risk of accidental contact. Shroud design affects board-level clearance requirements and environmental protection in the application.

Q: Are both components RoHS compliant?

A: Yes. The Phoenix Contact 1704437 is RoHS Compliant. The On Shore Technology OSTOQ027050 is ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Why is the Phoenix Contact 1704437 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The OSTOQ027050, maintained in active production status, provides equivalent functionality for ongoing applications requiring 2-position, 5.00mm pitch terminal block headers.
