Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702251 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Positions Per Level: 2
• Pitch: 0.400" (10.16mm)
• Width: 2.192" (55.68mm)
• Panel Thickness Range: 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Panel Mount Type: 2 Piece, Snap Lock - Front Flange
• Front Panel Wire Connection: Header, Male Pins
• Color: Green
• Voltage - UL: 600 V

Allowable Variation Parameters:

• Rear Panel Wire Connection: PCB Pins configuration (straight or right-angle)
• Current - UL: Equal to or greater than 5 A
• Series designation within COMBICON DFK family
• Product Status: Active or Obsolete
• Compliance certifications (RoHS, REACH)

The Phoenix Contact 1702251 has one identified substitute: part number 1701537, which maintains all mandatory matching parameters while offering enhanced current capacity and active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701537 serves as a direct substitute for the obsolete 1702251 based on dimensional and electrical compatibility. Both components maintain identical pitch, width, panel thickness accommodation, and voltage rating specifications. The 1701537 provides enhanced current capacity (66A versus 5A) and active product status, ensuring continued availability and compliance with current RoHS3 standards.

The primary design consideration is the rear panel connection configuration: the 1702251 features straight PCB pins while the 1701537 uses right-angle PCB pins. This difference requires evaluation of available PCB layout space and mounting orientation requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1701537 replace the 1702251 in existing designs?

A: Yes, provided the PCB layout accommodates right-angle pin orientation instead of straight pins. All electrical and mechanical parameters remain compatible.

Q: What is the significance of the current rating difference between these parts?

A: The 1701537 supports 66A current capacity compared to the 1702251's 5A rating. This represents an allowable variation parameter; the substitute part exceeds the original specification and maintains backward compatibility for applications requiring the original 5A capacity.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 1702251 carries RoHS Compliant status while the 1701537 carries ROHS3 Compliant status, indicating the substitute meets current regulatory requirements. The 1701537 also carries REACH Unaffected status.

Q: What packaging differences exist?

A: The 1702251 packaging specification is not provided. The 1701537 is supplied in Bulk packaging.

Q: How do the series designations differ?

A: The 1702251 belongs to the COMBICON DFK-PCV series while the 1701537 belongs to the COMBICON DFK-PC series. Both are within the Phoenix Contact COMBICON DFK terminal block family and maintain compatible form factors and electrical characteristics.

Q: What is the inventory status for these parts?

A: The 1702251 has 1112 pieces in stock (obsolete status). The 1701537 has 857 pieces in stock (active status), providing ongoing availability for new orders and replacements.
