OD512JE Equivalent & Substitute Parts

Part Overview

The OD512JE is a 5.1 kOhms ±5% 0.25W through-hole resistor in axial package configuration, manufactured by Ohmite as part of the Little Demon® OD series. This carbon composition resistor features pulse withstanding capability and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OD512JE is determined by the following critical parameters:

• Resistance Value: The substitute must maintain functional equivalence within circuit design tolerances. The OD512JE specifies 5.1 kOhms at ±5% tolerance.
• Power Rating: The substitute must support the same 0.25W (1/4W) power dissipation requirement.
• Package Configuration: The substitute must use axial through-hole package to ensure mechanical and electrical compatibility with existing PCB layouts.
• Physical Dimensions: The substitute must match the 0.098" Dia x 0.276" L (2.50mm x 7.00mm) form factor for board space constraints.
• Composition and Features: Carbon composition construction with pulse withstanding capability ensures performance characteristics are preserved.
• Compliance: RoHS3 compliance and MSL 1 rating must be maintained for regulatory and environmental requirements.

The OD472KE is listed as a substitute part. However, this part exhibits a resistance value of 4.7 kOhms with ±10% tolerance, which represents a deviation from the original 5.1 kOhms specification. This substitution is valid only in applications where the circuit design permits tolerance for the lower resistance value and wider tolerance band.

Parameter Comparison

Engineering Selection Recommendations

Both the OD512JE and OD472KE are obsolete products within the Little Demon® OD series. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment for current manufacturing standards.

The primary distinction between these parts is the resistance value and tolerance specification. The OD512JE provides 5.1 kOhms at ±5% tolerance, while the OD472KE provides 4.7 kOhms at ±10% tolerance. Selection between these parts depends on circuit design requirements and tolerance margins. The OD472KE represents a 7.8% nominal resistance reduction from the OD512JE specification.

Both parts share identical physical dimensions, power rating, package configuration, and composition characteristics, ensuring mechanical and thermal compatibility in axial through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the OD472KE directly replace the OD512JE in all applications?

A: The OD472KE shares the same package, power rating, and physical dimensions as the OD512JE. However, the resistance value differs (4.7 kOhms versus 5.1 kOhms). Substitution is valid only when circuit design tolerances accommodate the lower resistance value and the wider ±10% tolerance band.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by resistance value, tolerance, power rating, package configuration, physical dimensions, composition type, and compliance certifications. Deviations in any of these parameters may affect circuit performance or regulatory compliance.

Q: Are both parts suitable for new designs?

A: Both the OD512JE and OD472KE are classified as obsolete. For new designs, current-production alternatives from Ohmite or other manufacturers should be evaluated to ensure long-term component availability and supply chain stability.

Q: Do the physical dimensions match between these parts?

A: Yes. Both parts share identical dimensions of 0.098" Dia x 0.276" L (2.50mm x 7.00mm), ensuring compatibility with existing PCB layouts and through-hole mounting requirements.

Q: Are there compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring equivalent regulatory and environmental compliance for manufacturing and deployment.
