OF472JE Equivalent & Substitute Parts

Part Overview

The OF472JE is a 4.7 kOhms ±5% 0.5W through-hole resistor in axial configuration, manufactured by Ohmite as part of the Little Demon® OF series. This carbon composition resistor features pulse withstanding capability and is designed for applications requiring reliable fixed resistance in compact form factors. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OF472JE is determined by the following critical parameters:

• Resistance Value: Must remain 4.7 kOhms
• Power Rating: Must maintain 0.5W (1/2W) minimum
• Package Configuration: Must be axial through-hole format
• Physical Dimensions: Must match 0.150" Dia x 0.406" L (3.80mm x 10.30mm)
• Composition: Carbon composition construction
• Termination Count: Two-terminal configuration

The tolerance specification (±5% vs ±10%) represents the primary electrical difference among available substitutes. Substitutes with relaxed tolerance (±10%) are acceptable in applications where the tighter tolerance of the original part is not a functional requirement. All substitute candidates maintain identical resistance value, power rating, package type, physical dimensions, and composition.

Parameter Comparison

Engineering Selection Recommendations

The OF472KE serves as a direct substitute for the OF472JE in applications where tolerance specification is not a critical design parameter. Both components are manufactured by Ohmite within the Little Demon® OF series, share identical physical dimensions, power ratings, and composition characteristics, and maintain equivalent RoHS3 compliance and MSL ratings.

The primary distinction is tolerance: the OF472JE provides ±5% tolerance, while the OF472KE provides ±10% tolerance. Selection between these parts depends on circuit requirements for resistance accuracy. In circuits where the ±5% tolerance of the original part is mandatory, the OF472JE remains the required specification. In applications tolerant of ±10% variance, the OF472KE is electrically and mechanically compatible.

Both parts are classified as obsolete products. Availability through authorized distributors should be confirmed prior to procurement for production or high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can OF472KE replace OF472JE in any application?

A: The OF472KE is mechanically and electrically compatible with the OF472JE in applications where ±10% tolerance is acceptable. If the circuit design requires the ±5% tolerance specification of the original part, the OF472KE is not suitable.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both OF472JE and OF472KE measure 0.150" diameter by 0.406" length (3.80mm x 10.30mm) and are configured as axial through-hole components. They are mechanically interchangeable in PCB layouts.

Q: What is the difference between these two part numbers?

A: The primary difference is tolerance specification. OF472JE is rated ±5%, while OF472KE is rated ±10%. Both maintain 4.7 kOhms resistance, 0.5W power rating, carbon composition construction, and pulse withstanding features.

Q: Are both parts RoHS compliant?

A: Yes. Both OF472JE and OF472KE are ROHS3 compliant and carry MSL rating 1 (Unlimited), meeting current environmental and reliability standards.

Q: Why are both parts listed as obsolete?

A: Both the OF472JE and OF472KE are obsolete products from the Little Demon® OF series. Availability is limited to existing inventory through authorized distributors. For new designs, modern resistor alternatives should be evaluated.
