Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1770597 is determined by the following critical parameters:

• Pitch and Position Count: Both main and substitute parts maintain 0.591" (15.00mm) pitch with 8 positions per level, ensuring PCB footprint compatibility
• Mating Orientation: Horizontal with board configuration is preserved across all substitute options
• Voltage Rating: 600V rating is maintained, supporting equivalent electrical stress conditions
• Mounting Type: Through-hole mounting is consistent, allowing direct PCB integration without redesign
• RoHS Compliance: All parts meet RoHS requirements, ensuring regulatory alignment

The Phoenix Contact 1932559 qualifies as a substitute based on these core parameters. Variations in current rating, wire gauge range, termination method, and series designation reflect design evolution within the COMBICON product family while maintaining functional equivalence for the specified pitch, position count, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1932559 is the designated substitute for the obsolete 1770597 based on the following criteria:

Product Status Alignment: The 1932559 maintains active product status within the Phoenix Contact COMBICON family, ensuring continued availability and manufacturing support. The 1770597 obsolete classification necessitates transition to an active equivalent.

Regulatory Compliance: Both parts maintain RoHS compliance certification, satisfying environmental and regulatory requirements for electronic component procurement.

Functional Compatibility: The substitute part preserves the critical mechanical and electrical parameters required for direct PCB integration: identical pitch spacing, position count, mounting orientation, and voltage rating. These parameters ensure that existing PCB designs require no layout modifications.

Enhanced Electrical Capability: The 1932559 provides increased current rating (115A versus 66A) and expanded wire gauge acceptance (2-20 AWG versus 4-18 AWG), offering improved flexibility for applications within the original design envelope.

Termination Method Transition: The shift from screwless spring cage to screw-based rising cage clamp termination represents a design evolution. This change requires operator familiarity with screw-based assembly procedures but maintains equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 1932559 be used as a direct replacement for the 1770597 without PCB modification?

A: Yes. Both parts share identical pitch (15mm), position count (8), mating orientation (horizontal with board), and through-hole mounting configuration. PCB footprints are compatible without redesign.

Q: What is the primary difference between these two terminal blocks?

A: The main differences are product status (1770597 is obsolete; 1932559 is active), wire termination method (screwless spring cage versus screw-based rising cage clamp), current rating (66A versus 115A), and wire gauge range (4-18 AWG versus 2-20 AWG).

Q: Does the higher current rating of the 1932559 affect compatibility with existing designs?

A: No. The higher current rating (115A) is a capability enhancement that does not degrade performance in applications designed for the original 66A specification. The substitute part operates safely within the original design parameters.

Q: Are there packaging differences between these parts?

A: The 1770597 is supplied without specified packaging, while the 1932559 is supplied in bulk packaging. Verify packaging requirements with your procurement specifications.

Q: What wire gauge range should be used with the 1932559?

A: The 1932559 accepts wire gauges from 2-20 AWG, providing broader compatibility than the original 1770597 (4-18 AWG). Select wire gauge based on your application current requirements and circuit design specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1770597 and 1932559 are RoHS compliant, meeting environmental and regulatory standards for electronic component manufacturing and use.
