Phoenix Contact 1796597 Terminal Block Header – Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1796597 is a 6-position terminal block header with male pins, shrouded on all four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component operates at 12A (IEC) and 250V (IEC), featuring solder termination and explosion-proof construction with a locking ramp mechanism.

The 1796597 carries an obsolete product status. Identifying functionally equivalent substitute parts is necessary to maintain design compatibility and ensure continued availability for new production runs, repairs, and system upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1796597 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Current rating (12A IEC), voltage rating (250V IEC), and contact material specifications must match exactly
• Mechanical Compatibility: Position count (6), pitch (5.08mm), header orientation (vertical), shroud configuration (4-side), and contact tail length (3.90mm) must be identical
• Termination & Mounting: Solder termination and through-hole mounting type must be preserved
• Material & Safety Compliance: Housing material (Polyamide/Nylon), flammability rating (UL94 V-0), and RoHS compliance status must be maintained

The Phoenix Contact 1796364 meets all substitution criteria and is listed as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1796364 is the direct substitute for the obsolete 1796597. Both components share identical electrical ratings, mechanical dimensions, and safety certifications. The 1796364 carries active product status, ensuring long-term availability and supply chain continuity.

The 1796364 maintains RoHS3 compliance, exceeding the RoHS compliance level of the original part. Both components are classified as EAR99 and carry the same HTSUS code, confirming regulatory and trade equivalence.

The primary design difference lies in the feature set: the 1796597 includes a locking ramp mechanism, while the 1796364 incorporates a mating and mounting flange. This distinction does not affect electrical or mechanical compatibility in standard through-hole PCB applications. Component selection should be based on the specific mounting and retention requirements of the target application.

Frequently Asked Questions (FAQ)

Q: Can the 1796364 be used as a direct replacement for the 1796597 in existing designs?

A: Yes. Both components meet identical electrical (12A, 250V), mechanical (6-position, 5.08mm pitch, vertical orientation), and safety specifications (UL94 V-0, RoHS compliance). PCB footprints and solder pad layouts are compatible.

Q: What is the functional difference between the locking ramp and mating flange features?

A: The locking ramp on the 1796597 provides mechanical retention during mating. The mating and mounting flange on the 1796364 serves alignment and structural support functions. Feature selection depends on the connector interface design and retention strategy of the mating component.

Q: Are there any compliance or certification differences between these parts?

A: Both components carry UL94 V-0 flammability ratings and EAR99 export classification. The 1796364 meets ROHS3 compliance, while the 1796597 meets RoHS compliance. This represents an upgrade in regulatory status with no functional impact.

Q: What is the contact tail length, and why is it critical for substitution?

A: Both components feature a 0.154" (3.90mm) contact tail length. This dimension determines solder joint depth and PCB hole engagement. Matching tail length ensures proper solder fillet formation and mechanical stability in through-hole assembly.

Q: Can these components be used in explosion-proof applications?

A: Both the 1796597 and 1796364 are rated for explosion-proof construction. Compliance with specific explosion-proof standards depends on the complete system design and certification requirements of the target application.
