Substitute Part Grouping Explanation

Substitution of the OF752JE is determined by strict equivalence across the following critical parameters:

• Resistance value: 7.5 kOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Composition: Carbon Composition
• Package: Axial through-hole
• Physical dimensions: 0.150" Dia x 0.406" L
• Termination count: 2
• Pulse withstanding capability

The substitute part identified maintains identical electrical and mechanical specifications, ensuring direct functional replacement without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

The substitute OF752JE (active product status) is a direct equivalent to the obsolete main part number. Both components share identical electrical specifications, mechanical dimensions, and composition characteristics. The substitute maintains full RoHS compliance and carries active manufacturing status, ensuring long-term availability and supply chain continuity. The increased inventory level of the substitute part (1653 Pcs versus 811 Pcs) provides additional procurement flexibility. Both parts are MSL Level 1, requiring no special moisture handling during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can the active OF752JE substitute be used as a direct replacement for the obsolete OF752JE?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values, tolerances, power ratings, physical dimensions, and axial package configurations. No circuit modifications or PCB layout changes are required.

Q: Are there any differences in RoHS compliance between the main part and substitute?

A: Both parts meet RoHS requirements. The main part carries ROHS3 certification, while the substitute carries standard RoHS compliance. Both are suitable for applications requiring lead-free construction.

Q: What is the significance of the packaging difference (standard versus bulk)?

A: The packaging designation reflects order and delivery format. The substitute is available in bulk packaging, which may affect minimum order quantities and pricing. Electrical and mechanical performance remain identical regardless of packaging format.

Q: Does the pulse withstanding feature apply to both parts?

A: Yes. Both the main part and substitute incorporate pulse withstanding capability, maintaining identical transient response characteristics and reliability performance.

Q: Are moisture sensitivity considerations the same for both parts?

A: Yes. Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard storage conditions apply without special desiccant or controlled environment requirements.
