Phoenix Contact 1780529 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1780529 is a 2-position terminal block plug with female sockets, 0.098" (2.50mm) pitch, designed for 180° free-hanging in-line applications. This component features IDC (insulation displacement connector) termination and supports 4A at 125V per IEC standards. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1780529 is determined by the following critical parameters:

• Connector Type & Configuration: 2-position plug with female sockets
• Pitch Specification: 0.098" (2.50mm) center-to-center spacing
• Mounting Orientation: 180° free-hanging in-line configuration
• Electrical Performance: Current and voltage ratings must meet or exceed IEC specifications (4A / 125V minimum)
• Wire Compatibility: Wire gauge range must accommodate 22-24 AWG (0.25-0.34mm²)
• Termination Interface: Mechanical compatibility with mating connector systems
• Compliance: RoHS compliance status for regulatory alignment

The substitute part 1778832 maintains identical mechanical form factor, pitch, position count, and mounting orientation. While termination style differs (IDC vs. Screwless Spring Cage), both provide equivalent electrical connectivity for the specified wire gauge range and support higher electrical ratings, ensuring functional compatibility in replacement scenarios.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1778832 serves as a direct functional substitute for the obsolete 1780529 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical 2-position configuration, 2.50mm pitch, and 180° free-hanging in-line mounting. Physical form factor ensures drop-in replacement capability in existing connector systems.

Electrical Performance: The 1778832 exceeds the electrical requirements of the 1780529, providing 6A at 320V (IEC) compared to 4A at 125V. This enhanced rating ensures the substitute operates safely within or below the original design specifications.

Wire Gauge Accommodation: The substitute's 20-26 AWG range (0.14-0.5mm²) encompasses the original 22-24 AWG specification, maintaining compatibility with existing wire harnesses.

Regulatory Compliance: Both components maintain RoHS compliance. The substitute achieves ROHS3 certification, meeting current regulatory standards for new designs and replacements.

Product Availability: The 1778832 holds active product status with substantial inventory availability, ensuring reliable sourcing for production and maintenance applications.

Termination Consideration: The transition from IDC to Screwless Spring Cage termination requires verification that mating connector interfaces are compatible with the spring cage mechanism. This is the primary technical distinction requiring validation in specific applications.

Frequently Asked Questions (FAQ)

Q: Can the 1778832 directly replace the 1780529 in all applications?

A: The 1778832 provides mechanical and electrical compatibility for applications requiring 2-position, 2.50mm pitch terminal block plugs with 180° in-line orientation. The primary consideration is termination style compatibility. The 1780529 uses IDC termination, while the 1778832 uses Screwless Spring Cage. Verify that your mating connector system supports spring cage termination before substitution.

Q: What are the wire gauge compatibility differences?

A: The 1780529 accepts 22-24 AWG (0.25-0.34mm²). The 1778832 accepts 20-26 AWG (0.14-0.5mm²). Existing wire harnesses designed for 22-24 AWG are fully compatible with the substitute. The broader range of the 1778832 provides additional flexibility for future applications.

Q: Does the higher electrical rating of the 1778832 affect compatibility?

A: No. The 1778832's 6A / 320V rating exceeds the original 4A / 125V specification. In replacement scenarios, the substitute operates at lower stress levels than its rated capacity, ensuring safe and reliable operation.

Q: Are both parts RoHS compliant?

A: Yes. The 1780529 is RoHS Compliant. The 1778832 is ROHS3 Compliant, meeting the current and more stringent regulatory requirements for electronic components.

Q: What is the primary reason for substitution?

A: The 1780529 is classified as obsolete. The 1778832 is an active product with confirmed inventory availability, making it the appropriate choice for new designs and ongoing system maintenance where the 1780529 is no longer available from Phoenix Contact.

Q: Are there any performance differences in signal integrity or contact resistance?

A: Both components feature tin contact mating finish and are designed for equivalent electrical performance in terminal block applications. No performance degradation is expected when substituting the 1778832 for the 1780529 in compatible systems.
