Substitute Part Grouping Explanation

Substitution for the S5-4K7J8 is based on maintaining electrical and mechanical compatibility within the following criteria:

• Identical resistance value: 4.7 kOhms
• Identical power rating: 4W
• Identical package type: 8230 J-Lead
• Identical composition: Wirewound
• Identical operating temperature range: -55°C ~ 275°C
• Identical temperature coefficient: ±20ppm/°C
• Identical feature set: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety
• Identical RoHS compliance: ROHS3 Compliant
• Tolerance may vary within acceptable design margins

The S5-4K7F1 qualifies as a direct substitute with an upgrade in tolerance specification from ±5% to ±1%, providing improved accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the S5-4K7J8 and S5-4K7F1 are Active products with ROHS3 compliance and REACH compliance status. The S5-4K7F1 provides improved tolerance specification (±1% versus ±5%) while maintaining identical electrical performance, thermal characteristics, and safety features. Selection between these parts should be based on application tolerance requirements and inventory availability. Both parts are suitable for current sensing applications requiring flame-proof and pulse-withstanding characteristics across the full operating temperature range of -55°C to 275°C.

Frequently Asked Questions (FAQ)

Q: Can the S5-4K7F1 be used as a direct replacement for the S5-4K7J8?

A: Yes. The S5-4K7F1 is electrically and mechanically compatible with the S5-4K7J8. Both parts share identical resistance, power rating, package type, operating temperature range, and feature set. The primary difference is improved tolerance specification in the S5-4K7F1.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance defines the acceptable deviation from the nominal resistance value. The S5-4K7F1 with ±1% tolerance provides tighter resistance accuracy compared to the S5-4K7J8 with ±5% tolerance. Applications requiring precise current sensing or tight circuit performance may benefit from the improved tolerance specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the S5-4K7J8 and S5-4K7F1 use the 8230 J-Lead package with identical dimensions: 0.819" L x 0.296" W (20.80mm x 7.50mm) and maximum seated height of 0.319" (8.10mm).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH affected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0080. Both maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What applications are these parts suitable for?

A: These wirewound resistors are designed for current sensing applications requiring flame-proof, moisture-resistant, and pulse-withstanding characteristics. The 4W power rating and extended operating temperature range (-55°C to 275°C) support demanding industrial and automotive applications.
