WHA5R0FE Equivalent & Substitute Parts

Part Overview

The WHA5R0FE is a 5 Ohm ±1% 0.5W through-hole resistor manufactured by Ohmite in the WH series. This axial wirewound resistor operates across -55°C to 150°C and is ROHS3 compliant. The part is currently active in production with 1025 units in stock. Substitute parts are necessary when packaging requirements differ, when non-inductive characteristics are required for specific circuit applications, or when alternative series options provide equivalent electrical performance with different mechanical or compliance attributes.

Substitute Part Grouping Explanation

Substitution eligibility for the WHA5R0FE is determined by matching the following core electrical and mechanical parameters: 5 Ohm resistance value, ±1% tolerance, 0.5W power rating, wirewound composition, ±50ppm/°C temperature coefficient, -55°C to 150°C operating range, axial package type, and 0.100" Dia x 0.200" L dimensions.

The WHA5R0FE has two qualified substitutes:

WHA5R0FET (Direct Manufacturer Substitute): Identical electrical specifications and dimensions. Differs in packaging format (Tape & Reel vs. bulk) and includes non-inductive feature. RoHS compliant with MSL rating of 1 (Unlimited).

WNA5R0FE (Parametric Equivalent): Belongs to the WN series instead of WH series. Maintains all electrical parameters and physical dimensions. Includes non-inductive feature. ROHS3 compliant with MSL Not Applicable.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet regulatory compliance requirements. Selection between WHA5R0FE and its substitutes depends on specific application requirements:

WHA5R0FE is the baseline specification. Use when standard wirewound characteristics are acceptable and bulk packaging is preferred.

WHA5R0FET provides identical electrical and mechanical performance with non-inductive construction. Select this part when tape and reel packaging is required for automated assembly processes or when non-inductive characteristics are specified in circuit design.

WNA5R0FE offers parametric equivalence with non-inductive construction in the WN series. This option is suitable when series interchangeability is acceptable and non-inductive performance is required.

All parts carry ROHS3 or equivalent RoHS compliance and are suitable for -55°C to 150°C operating environments.

Frequently Asked Questions (FAQ)

Q: Can WHA5R0FET replace WHA5R0FE in all applications? A: Yes, provided the circuit design does not require standard inductive characteristics. WHA5R0FET maintains identical resistance, tolerance, power rating, temperature coefficient, and physical dimensions. The non-inductive feature is an enhancement that does not degrade performance in standard applications.

Q: What is the difference between WHA5R0FE and WNA5R0FE? A: Both parts are parametrically equivalent with identical electrical specifications and dimensions. The primary difference is series designation (WH vs. WN). WNA5R0FE includes non-inductive construction. Both are ROHS3 compliant and suitable for the same operating temperature range.

Q: When should I use tape and reel packaging (WHA5R0FET)? A: Tape and reel packaging is standard for high-volume automated assembly operations. Use WHA5R0FET when your manufacturing process requires reel-fed component placement equipment.

Q: Are all three parts interchangeable on a PCB? A: Yes. All three parts share identical axial package dimensions (0.100" Dia x 0.200" L) and two-terminal configuration, making them mechanically and electrically interchangeable in through-hole applications.

Q: What does non-inductive mean in the context of these resistors? A: Non-inductive construction reduces parasitic inductance in the resistor element, making these parts suitable for high-frequency applications where inductive effects could impact circuit performance.
