Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 1701540 qualifies as a direct substitute for the 1702028 based on the following matching parameters:

• Identical position count (3 positions per level)
• Identical pitch spacing (0.400" / 10.16mm)
• Identical panel mount configuration (2 piece, snap lock front flange)
• Identical connector interface (header male pins to PCB right-angle pins)
• Identical physical width (2.592" / 65.84mm)
• Identical panel thickness tolerance (0.039 ~ 0.118" / 1.0 ~ 3.0mm)
• Identical color designation (green)
• Same series family (COMBICON DFK-PC)
• Equivalent RoHS compliance status

The primary distinction between these parts is product status: 1702028 is obsolete while 1701540 is active production. Electrical specifications differ (voltage and current ratings), requiring application-level verification for suitability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701540 is the designated substitute for the obsolete 1702028. Both components share identical mechanical and dimensional specifications, ensuring direct form-fit compatibility in existing PCB layouts and panel mounting configurations.

Selection between these parts depends on application electrical requirements. The 1702028 supports 600 V at 5 A, while the 1701540 supports 300 V at 66 A. Applications requiring the higher voltage rating of the original part must evaluate whether the 1701540's reduced voltage specification is acceptable for the intended circuit. Conversely, applications requiring higher current capacity benefit from the 1701540's enhanced current rating.

Both parts maintain RoHS compliance and identical moisture sensitivity classification, supporting equivalent environmental performance in standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 1701540 be used as a direct replacement for the 1702028 in existing assemblies?

A: Mechanical and dimensional compatibility is confirmed. The 1701540 maintains identical pitch, position count, panel mount configuration, and physical dimensions. Electrical specification differences (voltage and current ratings) require application-level assessment to confirm suitability.

Q: What are the key differences between these two parts?

A: The primary differences are product status (1702028 is obsolete; 1701540 is active) and electrical ratings. The 1702028 is rated 600 V / 5 A, while the 1701540 is rated 300 V / 66 A. All mechanical, dimensional, and interface specifications are identical.

Q: Are there packaging differences between the 1702028 and 1701540?

A: The 1702028 packaging is not specified in available documentation. The 1701540 is supplied in bulk packaging. Packaging format should be confirmed with the supplier for procurement purposes.

Q: Do both parts meet the same compliance standards?

A: Both the 1702028 and 1701540 are RoHS compliant and carry identical moisture sensitivity level (MSL 1 - Unlimited). Both share the same ECCN and HTSUS classifications.

Q: Which part should be selected for new designs?

A: The 1701540 is the active production part and is the appropriate choice for new designs. The 1702028 is obsolete and should only be used for replacement in existing systems where electrical specifications are confirmed compatible.
