Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 95J3K9 is determined by strict equivalence across the following parameters:

• Resistance value: 3.9 kOhms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±30ppm/°C
• Safety features: Flame retardant coating

The Ohmite 25J3K9 meets all substitution criteria. Both parts are manufactured by Ohmite, share identical electrical specifications, and maintain compatible axial package geometry suitable for through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 95J3K9 and 25J3K9 are Active products with identical electrical and safety specifications. Selection between these parts is based on packaging and dimensional considerations:

The 95J3K9 is supplied in Box packaging with dimensions of 0.264" diameter × 0.969" length. The 25J3K9 is supplied in Bulk packaging with slightly larger dimensions of 0.276" diameter × 1.016" length. Both parts maintain RoHS non-compliant status and EAR99 export classification. The marginal dimensional difference (0.012" diameter increase, 0.047" length increase) is within typical PCB layout tolerances for axial through-hole components.

Frequently Asked Questions (FAQ)

Q: Can the Ohmite 25J3K9 directly replace the 95J3K9 in existing designs?

A: Yes. Both parts share identical electrical specifications (3.9 kOhms ±5%, 5W, ±30ppm/°C) and axial package configuration. The 25J3K9 dimensions are marginally larger but remain compatible with standard through-hole PCB layouts designed for 5W axial resistors.

Q: What is the difference between the 95J3K9 and 25J3K9?

A: The primary differences are series designation (90 vs. 20), packaging format (Box vs. Bulk), and physical dimensions. The 25J3K9 is 0.012" larger in diameter and 0.047" longer. All electrical and safety characteristics are equivalent.

Q: Are both parts RoHS compliant?

A: No. Both the 95J3K9 and 25J3K9 are RoHS non-compliant. If RoHS compliance is required, alternative component sourcing is necessary.

Q: What packaging considerations apply to these parts?

A: The 95J3K9 is supplied in Box packaging, while the 25J3K9 is supplied in Bulk packaging. Box packaging typically includes protective containment for smaller quantities, whereas Bulk packaging is used for higher-volume orders. This distinction does not affect electrical performance or mechanical compatibility.

Q: Are there any export restrictions on these parts?

A: Both parts are classified under ECCN EAR99 and HTSUS code 8533.21.0080, indicating standard export classification for wirewound resistors with no additional restrictions beyond standard commercial export procedures.
