WHC150FET Equivalent & Substitute Parts

Part Overview

The WHC150FET is a 150 Ohms ±1% 2W through-hole resistor manufactured by Ohmite in axial wirewound composition. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are identified when packaging format or specific feature requirements differ while maintaining identical electrical performance and mechanical compatibility within the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WHC150FET is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 150 Ohms
• Tolerance: ±1%
• Power rating: 2W
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C ~ 150°C

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.180" Dia x 0.449" L (4.57mm x 11.40mm)
• Number of terminations: 2

Variable Parameters (Allowed to Differ):

• Packaging format (Tape & Reel, Cut Tape, Bulk)
• Specific wirewound features (standard vs. non-inductive)
• Series designation

The identified substitutes maintain full electrical and mechanical compatibility while differing only in packaging delivery format or internal construction features that do not affect circuit performance.

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance. Selection between WHC150FET, WNC150FET, and WHC150FE is determined by packaging and supply requirements:

WHC150FET (Tape & Reel): Primary selection for automated assembly processes requiring reel-based component feeding. Inventory: 622 Pcs.

WNC150FET (Cut Tape): Selection for applications requiring non-inductive wirewound construction. Cut tape format supports both manual and semi-automated assembly. Inventory: 3350 Pcs.

WHC150FE (Bulk): Selection for manual assembly or prototype applications where individual component handling is required. Inventory: 1856 Pcs.

All parts are electrically and mechanically interchangeable within the specified parameters. Compliance certifications (ROHS3, REACH Unaffected, EAR99) are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can WHC150FET be replaced with WNC150FET in production assembly? A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, and temperature specifications. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and the non-inductive feature of WNC150FET. Assembly equipment compatibility should be verified based on tape specifications.

Q: What is the difference between WHC150FET and WHC150FE? A: Both are standard wirewound 150 Ohm 2W axial resistors from the WH series with identical electrical and mechanical specifications. The difference is packaging format: WHC150FET is supplied in Tape & Reel format, while WHC150FE is supplied in Bulk format.

Q: Is the non-inductive feature of WNC150FET critical for substitution? A: The non-inductive construction of WNC150FET is a feature that does not prevent substitution. Standard wirewound resistors (WHC150FET, WHC150FE) can be substituted for non-inductive versions in applications where inductance is not a limiting factor. Application requirements determine whether non-inductive construction is necessary.

Q: Are all three parts ROHS3 compliant? A: Yes. WHC150FET, WNC150FET, and WHC150FE are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What packaging format should be selected for high-volume automated assembly? A: Tape & Reel format (WHC150FET) is standard for automated pick-and-place assembly. Cut Tape format (WNC150FET) supports semi-automated processes. Bulk format (WHC150FE) is suitable for manual assembly or low-volume applications.
