Substitute Part Grouping Explanation

Substitution for the TAP600K4R0 is based on electrical and mechanical parameter equivalence within the TAP600 series. The substitute part must maintain identical specifications across the following critical parameters:

  • Resistance value: 4 Ohms
  • Tolerance: ±10%
  • Power rating: 600W
  • Composition: Thick Film
  • Temperature coefficient: ±150ppm/°C
  • Operating temperature range: -55°C to 150°C
  • Coating type: Epoxy Coated
  • Mounting configuration: Flanged with M5 threaded leads
  • Physical dimensions: 2.559" L × 2.362" W × 1.280" H (seated max)

The TAP600K4R0E meets all these criteria and is classified as an active production part within the same series.

Engineering Selection Recommendations

The TAP600K4R0E is the direct functional equivalent of the TAP600K4R0. Both components are electrically and mechanically identical across all specified parameters. The primary distinction is product status and regulatory compliance.

The TAP600K4R0E is an active production part with ROHS3 compliance, whereas the TAP600K4R0 is obsolete and RoHS non-compliant. For new designs or component replenishment, the TAP600K4R0E is the appropriate selection. Both parts share identical mechanical mounting interfaces, electrical performance characteristics, and thermal operating ranges, ensuring direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can TAP600K4R0E be used as a direct replacement for TAP600K4R0?

A: Yes. The TAP600K4R0E is electrically and mechanically identical to the TAP600K4R0 across all specified parameters, including resistance, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and mounting configuration. No circuit or mechanical modifications are required.

Q: What is the difference between TAP600K4R0 and TAP600K4R0E?

A: The primary differences are product status and regulatory compliance. The TAP600K4R0 is obsolete and RoHS non-compliant. The TAP600K4R0E is an active production part with ROHS3 compliance. Packaging differs (Box vs. Bulk), but electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting TAP600K4R0E for TAP600K4R0?

A: No compatibility concerns exist. Both parts feature identical M5 threaded leads, flanged mounting configuration, and physical dimensions. PCB layouts, mechanical mounting structures, and electrical circuits require no modification.

Q: What does ROHS3 compliance mean for the TAP600K4R0E?

A: ROHS3 compliance indicates the component meets the Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials in electrical and electronic equipment. This certification is relevant for applications subject to EU regulatory requirements or equivalent standards.

Q: Can the TAP600K4R0 be used in new designs?

A: The TAP600K4R0 is obsolete and not recommended for new designs. The TAP600K4R0E should be specified instead to ensure ongoing manufacturing support, supply chain availability, and compliance with current regulatory standards.
