SCHURTER 4300.0603 Power Entry Connector - Equivalent & Substitute Parts

Part Overview

The SCHURTER 4300.0603 is a Power Entry Connector Plug with IEC 320-C15 female sockets, designed for free hanging (in-line) mounting applications. This connector accommodates 10A at 250VAC with screw termination and unfiltered commercial design. The part is currently obsolete, making identification of equivalent substitute components essential for ongoing maintenance, repair, and new design implementations where this connector specification is required.

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 4300.0603 are qualified based on strict electrical and mechanical parameter alignment:

Primary Substitution Criteria:

• Connector Style: IEC 320-C15 (mandatory match)
• Connector Type: Plug, Female Sockets (mandatory match)
• Current Rating: 10A (mandatory match)
• Voltage Rating: 250VAC (mandatory match)
• Number of Positions: 3 (mandatory match)
• Mounting Type: Free Hanging (In-Line) (mandatory match)
• Termination: Screw (mandatory match)
• Filter Type: Unfiltered - Commercial (mandatory match)

Two substitute parts meet these criteria: SCHURTER 4781.0100 and Qualtek 709-00/00. Both maintain identical electrical specifications and mechanical configuration, ensuring direct functional equivalence in applications requiring the 4300.0603 connector.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 4781.0100 is the primary recommended substitute. This part maintains active product status with full electrical and mechanical equivalence to the 4300.0603. The material flammability rating improves to UL94 V-0 (compared to V-2 on the original), and regulatory approvals include cULus and VDE certification. Current inventory availability is 3753 units.

Qualtek 709-00/00 serves as a secondary substitute option. While electrically and mechanically equivalent with matching UL94 V-0 flammability rating and CSA, UL, VDE approvals, this part carries obsolete product status. Inventory availability is 1172 units. Selection of this substitute should account for long-term supply chain considerations due to obsolescence designation.

Both substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 4781.0100 directly replace SCHURTER 4300.0603 in existing applications?

A: Yes. The 4781.0100 maintains identical electrical specifications (10A, 250VAC), connector configuration (IEC 320-C15, 3-position), mounting type (free hanging in-line), and termination method (screw). The improved flammability rating (UL94 V-0) and active product status make this the preferred direct replacement.

Q: What is the difference between the material flammability ratings on these parts?

A: The original 4300.0603 carries UL94 V-2 rating, while both substitutes (4781.0100 and 709-00/00) carry UL94 V-0 rating. UL94 V-0 represents superior flame resistance performance. This difference does not prevent substitution; it represents an improvement in material performance.

Q: Are there any packaging differences between these substitutes?

A: The 4300.0603 packaging is listed as unspecified. Both substitutes are supplied in bulk packaging, which is standard for this connector category.

Q: Which substitute should be selected for new designs?

A: SCHURTER 4781.0100 is the appropriate choice for new designs. Active product status ensures long-term availability and supply chain stability. The part meets all electrical, mechanical, and regulatory requirements with enhanced material specifications.

Q: Can Qualtek 709-00/00 be used as a substitute?

A: Qualtek 709-00/00 is electrically and mechanically equivalent and carries obsolete product status. Use of this substitute should be evaluated based on application requirements and supply chain strategy, as obsolete designation may impact future availability.
