Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1703263 is determined by strict alignment of the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-IPCV series
• Electrical Specifications: Voltage rating (600V UL) and current capacity (5A) must be identical
• Mechanical Configuration: Position count (7), pitch (0.400"/10.16mm), and connection types (female sockets front, straight PCB pins rear) must match exactly
• Environmental Compliance: RoHS compliance and MSL rating must be equivalent or superior
• Panel Mount Type: Snap lock mechanism must be compatible with the application's mounting requirements

The Phoenix Contact 1703108 qualifies as a substitute based on these parameters. Both parts share identical electrical ratings, position configuration, pitch spacing, and environmental compliance specifications. The primary distinction lies in physical width and panel mount type variation, which does not affect electrical or functional compatibility within the COMBICON DFK-IPCV series framework.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1703108 is the qualified substitute for the obsolete 1703263 within the COMBICON DFK-IPCV terminal block family. Both components maintain identical electrical performance specifications (600V UL, 5A current), mechanical pitch and position configuration, and environmental compliance certifications.

The 1703108 carries active product status, ensuring continued availability and supply chain reliability. The width differential (3.750" versus 4.417") and panel mount type variation (standard snap lock versus front flange snap lock) represent design refinements within the series and do not compromise functional compatibility for applications requiring 7-position, 0.400" pitch terminal block headers with female socket front connections.

Selection between these parts should be based on specific panel mounting geometry requirements and available panel space. Both parts satisfy identical electrical and environmental specifications for 600V, 5A applications within the COMBICON DFK-IPCV series.

Frequently Asked Questions (FAQ)

Q: Can the 1703108 directly replace the 1703263 in existing installations?

A: Electrical and functional compatibility is confirmed. Physical installation feasibility depends on panel mounting space and flange configuration requirements specific to your application. The width difference (3.750" versus 4.417") and panel mount type variation must be evaluated against your mechanical constraints.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The 1703263 is classified as obsolete, indicating discontinued manufacturing. The 1703108 maintains active status, ensuring ongoing availability, supply chain support, and manufacturing consistency for new procurements and system maintenance.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both the 1703263 and 1703108 operate at 600V UL voltage rating with 5A current capacity. Pitch spacing (0.400"/10.16mm) and position count (7) are identical.

Q: What does the panel mount type difference mean?

A: The 1703263 features a 2-piece snap lock with front flange, while the 1703108 uses a 2-piece snap lock without specified flange designation. Both employ snap lock mechanisms; the flange variation affects panel mounting geometry and should be evaluated against your specific installation requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1703263 and 1703108 are RoHS compliant with MSL rating of 1 (Unlimited), meeting equivalent environmental and regulatory standards.

Q: What is the pitch specification, and why does it matter?

A: Both parts feature 0.400" (10.16mm) pitch spacing. This specification determines compatibility with mating connectors and PCB layout requirements. Identical pitch ensures mechanical and electrical interchangeability at the connection interface.
