Ohmite 43F470 Equivalent & Substitute Parts

Part Overview

The Ohmite 43F470 is a 470 Ohms ±1% 3W through-hole resistor with axial wirewound construction, part of the Ohmicone® 40 series. This component is currently active in production and available in box packaging with 900 pieces in stock. The part operates across a temperature range of -55°C to 275°C with a temperature coefficient of ±20ppm/°C.

Substitute parts are identified when they maintain identical electrical specifications (resistance value, tolerance, power rating, and composition) while potentially offering different packaging formats, compliance certifications, or physical dimensions within acceptable mechanical tolerances for axial wirewound resistors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 43F470 is determined by strict equivalence in the following core electrical parameters:

• Resistance value: 470 Ohms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial through-hole

All identified substitute parts maintain these electrical specifications. Variations in packaging format (box versus bulk), physical dimensions, temperature coefficient ranges, maximum operating temperature, and regulatory compliance certifications do not affect functional interchangeability in applications where the core electrical parameters are the design requirement.

Parameter Comparison

Engineering Selection Recommendations

All three parts—43F470, 43F470E, and ALSR03470R0FE12—are electrically equivalent for applications requiring a 470 Ohms ±1% 3W axial wirewound resistor.

The 43F470E (Ohmite) is a direct manufacturer equivalent differing only in packaging format (bulk versus box) and RoHS compliance status. This part is suitable for applications where RoHS compliance is required and bulk packaging is acceptable.

The ALSR03470R0FE12 (Vishay Dale) is functionally equivalent with the following distinctions: it features a moisture-resistant construction, operates across an extended lower temperature range (-65°C versus -55°C), has a slightly higher temperature coefficient (±30ppm/°C versus ±20ppm/°C), and maintains a smaller physical footprint (0.180" diameter versus 0.220" diameter). This part is suitable for applications where moisture resistance, extended low-temperature operation, or space constraints are design considerations. ROHS3 compliance is available with this substitute.

Selection between these parts depends on specific application requirements regarding regulatory compliance, packaging preferences, physical space constraints, and environmental operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 43F470E be used as a direct replacement for the 43F470?

A: Yes. Both parts are manufactured by Ohmite with identical electrical specifications (470 Ohms ±1%, 3W, wirewound, axial). The primary difference is packaging format: 43F470 is supplied in box packaging while 43F470E is supplied in bulk packaging. RoHS compliance status also differs. Functional interchangeability is complete.

Q: Is the ALSR03470R0FE12 compatible with the 43F470 in all applications?

A: The ALSR03470R0FE12 is electrically equivalent for the core function (470 Ohms ±1%, 3W, wirewound, axial). However, design-specific considerations apply: the temperature coefficient is ±30ppm/°C (versus ±20ppm/°C), the maximum operating temperature is 250°C (versus 275°C), and the physical dimensions are smaller. Applications with tight temperature coefficient requirements or maximum temperature specifications near 275°C should verify compatibility. Applications benefiting from moisture resistance and extended low-temperature operation (-65°C) may prefer this substitute.

Q: What is the significance of the physical dimension differences between the 43F470 and ALSR03470R0FE12?

A: The ALSR03470R0FE12 has a smaller diameter (0.180" versus 0.220") and shorter length (0.500" versus 0.594"). These differences may affect board layout and mechanical fit. Verify that PCB footprints and mechanical clearances accommodate the smaller dimensions before substitution.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a regulatory and material composition requirement, not an electrical performance specification. All three parts deliver identical electrical performance. Selection between RoHS-compliant and non-compliant versions depends on application regulatory requirements and end-market destination.

Q: Are all three parts suitable for high-temperature applications?

A: The 43F470 and 43F470E both operate to 275°C maximum. The ALSR03470R0FE12 operates to 250°C maximum. For applications requiring operation above 250°C, the 43F470 or 43F470E are required. For applications operating below 250°C, all three parts are suitable.
