95J4K7 Equivalent & Substitute Parts Reference

Part Overview

The Ohmite 95J4K7 is a 4.7 kOhms ±5% 5W through-hole axial wirewound resistor with flame retardant coating and safety features. This component is classified as Active product status with 869 pieces currently in stock. The 95J4K7 operates within the 90 series product line and is designed for applications requiring reliable power dissipation in through-hole configurations. Substitute parts become necessary when the primary part is unavailable, when alternative packaging formats are required for manufacturing processes, or when inventory constraints necessitate equivalent alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 95J4K7 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 4.7 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±30ppm/°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)
• Terminations: 2 (exact match required)

The Ohmite 25J4K7 qualifies as a direct substitute because it maintains identical electrical characteristics and functional features across all critical parameters. The primary distinction between the main part and substitute is the packaging format (Box versus Bulk) and minor dimensional variations within acceptable tolerances for axial through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Both the 95J4K7 and 25J4K7 maintain Active product status with Ohmite, ensuring continued manufacturer support and availability. Both components carry identical RoHS non-compliant classification, making them suitable for applications where RoHS compliance is not a requirement. The electrical performance characteristics are identical across resistance, tolerance, power rating, and temperature coefficient specifications.

The 25J4K7 substitute offers higher current inventory availability (957 pieces versus 869 pieces), which may provide supply chain advantages in high-volume procurement scenarios. The dimensional variation between the two parts (0.264" to 0.276" diameter and 0.969" to 1.016" length) remains within acceptable tolerances for standard through-hole PCB mounting applications and does not affect electrical performance or thermal dissipation characteristics.

Selection between the main part and substitute should be based on packaging requirements (Box versus Bulk format) and inventory availability for your specific procurement timeline.

Frequently Asked Questions (FAQ)

Q: Can the 25J4K7 be used as a direct replacement for the 95J4K7 in existing designs?

A: Yes. Both components are electrically and functionally identical across all critical parameters: 4.7 kOhms resistance, ±5% tolerance, 5W power rating, wirewound composition, axial package type, and ±30ppm/°C temperature coefficient. The dimensional variation is within acceptable tolerances for through-hole PCB mounting.

Q: What is the primary difference between these two parts?

A: The main differences are packaging format (95J4K7 ships in Box; 25J4K7 ships in Bulk) and minor dimensional variations. The 25J4K7 has a slightly larger diameter (0.276" versus 0.264") and length (1.016" versus 0.969"), but both maintain standard axial through-hole compatibility.

Q: Are there any compliance or certification differences between the 95J4K7 and 25J4K7?

A: Both parts share identical RoHS non-compliant status and ECCN/HTSUS classifications. No compliance differences exist between the two components.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on packaging preference (Box or Bulk) and current inventory availability. Both maintain Active product status with Ohmite.

Q: Do the dimensional differences affect thermal performance?

A: No. The minor dimensional variations do not impact thermal dissipation or electrical performance. Both components are rated for identical 5W power dissipation and maintain the same temperature coefficient specification.
