Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702303 is determined by the following critical parameters:

• Pitch (0.400" / 10.16mm): Substitute parts must maintain identical pitch spacing to ensure mechanical and electrical compatibility with existing mating connectors and PCB layouts.
• Panel Mount Type (2 Piece, Snap Lock - Front Flange): The mounting mechanism must be identical to preserve panel integration and mechanical stability.
• Panel Thickness Tolerance (0.039 ~ 0.118" / 1.0 ~ 3.0mm): Substitute parts must support the same panel thickness range for proper installation.
• Voltage Rating (600 V UL): Electrical isolation and safety requirements must be maintained at or above this specification.
• Color (Green): Visual identification and circuit designation must remain consistent.
• RoHS Compliance: Environmental and regulatory compliance status must be maintained.

The identified substitute part 1701582 shares the core mechanical mounting parameters (pitch, panel mount type, panel thickness, color, and RoHS compliance) with the main part. However, differences exist in position count, current rating, rear panel connection type, and product status, which must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1702303 is classified as obsolete. The substitute part 1701582 maintains mechanical compatibility through identical pitch spacing, panel mount configuration, panel thickness tolerance, voltage rating, color designation, and RoHS compliance status.

Selection of 1701582 as a substitute requires evaluation of the following application-specific factors:

• Position Count Difference: The main part provides 7 positions per level, while the substitute provides 6 positions. Circuit designs requiring all 7 positions cannot use this substitute without redesign.
• Current Rating Difference: The main part is rated for 5 A per position, while the substitute is rated for 66 A per position. Applications with current requirements exceeding 5 A per position benefit from the higher rating of the substitute.
• Rear Connection Type: The main part features straight PCB pins, while the substitute features right-angle PCB pins. PCB layout compatibility must be verified based on available board space and connector orientation requirements.
• Product Status: The substitute part 1701582 is active and currently in production, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can 1701582 be used as a direct replacement for 1702303?

A: Mechanical and electrical compatibility exists for the core mounting and voltage parameters. However, the 6-position configuration of 1701582 differs from the 7-position configuration of 1702303. Direct substitution is only possible if the circuit design can accommodate the reduced position count. Additionally, the right-angle PCB pin configuration of 1701582 differs from the straight pin configuration of 1702303, requiring PCB layout verification.

Q: What are the critical parameters for substitution compatibility?

A: Pitch spacing (0.400" / 10.16mm), panel mount type (2 Piece, Snap Lock - Front Flange), panel thickness tolerance (0.039 ~ 0.118" / 1.0 ~ 3.0mm), voltage rating (600 V UL), color (Green), and RoHS compliance status are the primary parameters determining substitution eligibility.

Q: Does the higher current rating of 1701582 affect compatibility?

A: The 66 A current rating of 1701582 exceeds the 5 A rating of 1702303. This represents an enhancement in current-carrying capacity and does not create compatibility issues for applications within the original 5 A specification. Applications requiring higher current density benefit from this increased rating.

Q: How does the PCB pin configuration difference impact selection?

A: The main part 1702303 features straight PCB pins, while substitute 1701582 features right-angle PCB pins. This difference affects PCB layout and connector orientation. Straight pins are suitable for vertical board mounting, while right-angle pins are suitable for horizontal or edge-mounted configurations. PCB design must accommodate the selected pin orientation.

Q: Is 1701582 suitable for new designs?

A: Yes. Part 1701582 is classified as active and currently in production. It meets all RoHS compliance requirements and provides enhanced current-carrying capacity. New designs should evaluate whether the 6-position configuration and right-angle pin orientation align with circuit requirements.
