Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1701605 qualifies as a direct substitute for the 1701760 based on the following critical parameters:

• Identical series designation (COMBICON DFK-PC)
• Matching position count (9 positions)
• Identical pitch specification (0.400" / 10.16mm)
• Identical front panel wire connection type (Header, Male Pins)
• Identical rear panel connection configuration (PCB Pins - Right Angle)
• Identical physical dimensions (Width: 4.992" / 126.80mm)
• Identical panel thickness tolerance (0.039 ~ 0.118" / 1.0 ~ 3.0mm)
• Identical panel mount type (2 Piece, Snap Lock - Front Flange)
• Identical voltage rating (600 V UL)
• Identical color specification (Green)
• Identical features (Threaded Mating Lock, Shield Connection Front Side)
• Identical number of levels (1)
• Identical RoHS compliance status
• Identical MSL rating (1 - Unlimited)

The primary distinction is product status: the 1701605 is active production, whereas the 1701760 is obsolete. The 1701605 also carries a higher current rating (66 A versus 5 A), which represents an enhanced capability suitable for applications requiring greater current capacity.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701605 is the appropriate substitute for the obsolete 1701760. Both components maintain identical mechanical and electrical specifications across all critical parameters, ensuring direct form-fit-function compatibility. The 1701605 is currently in active production status, providing assured supply chain availability and long-term support.

The elevated current rating of the 1701605 (66 A versus 5 A) does not present a compatibility concern; it represents an improved specification that maintains backward compatibility with applications designed for the original 5 A rating. Both components carry identical RoHS compliance certification and MSL ratings, confirming suitability for equivalent environmental and manufacturing conditions.

Frequently Asked Questions (FAQ)

Q: Can the 1701605 be used as a direct replacement for the 1701760 in existing designs?

A: Yes. The 1701605 maintains identical mechanical dimensions, pitch, mounting configuration, and electrical ratings (voltage specification). The components are mechanically and electrically interchangeable.

Q: What is the significance of the different current ratings (5 A versus 66 A)?

A: The 1701605 carries a higher current capacity specification. This represents an enhanced capability and does not restrict its use in applications originally designed for the 5 A rating. The higher rating provides additional margin for current-carrying applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1701760 and 1701605 are RoHS compliant and carry identical MSL ratings (1 - Unlimited), confirming equivalent environmental and manufacturing compliance.

Q: Why is the 1701760 classified as obsolete?

A: The 1701760 has been superseded by the 1701605 in Phoenix Contact's product line. The 1701605 provides equivalent functionality with active production status and improved current capacity.

Q: Are there any packaging differences between these parts?

A: The 1701760 was supplied with standard packaging, while the 1701605 is supplied in bulk packaging. This distinction does not affect component functionality or compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching series designation, position count, pitch, connection types, physical dimensions, panel mount configuration, voltage rating, color, features, and compliance certifications. The 1701605 matches all these parameters with the 1701760.
