Key Parameters

Substitute Part Grouping Explanation

Substitution of the S3-22RJ1 is determined by the following critical parameters that must remain constant:

• Resistance value: 22 Ohms
• Power rating: 3W
• Package / Case: 6327 J-Lead
• Physical dimensions: 0.626" L x 0.272" W (15.90mm x 6.90mm)
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C ~ 275°C
• Composition: Wirewound
• Features: Current Sense, Flame Proof, Moisture Resistant, Pulse Withstanding, Safety

The S3-22RF1 qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

Both the S3-22RJ1 and S3-22RF1 are Active products manufactured by Riedon and maintain full ROHS3 compliance and REACH affected status. The S3-22RF1 provides improved tolerance specification at ±1% compared to the ±5% tolerance of the S3-22RJ1, while maintaining identical electrical performance, thermal characteristics, and mechanical compatibility. Selection between these parts depends on circuit tolerance requirements and application specifications.

Frequently Asked Questions (FAQ)

Q: Can the S3-22RF1 directly replace the S3-22RJ1 in existing designs?

A: Yes. The S3-22RF1 maintains identical resistance value, power rating, package dimensions, temperature coefficient, and operating temperature range. The improved tolerance specification of ±1% is a functional enhancement that does not compromise compatibility.

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

A: The tolerance specification differs: S3-22RJ1 is ±5% while S3-22RF1 is ±1%. All other electrical and mechanical parameters remain identical.

Q: Are both parts available in the same packaging format?

A: Yes. Both the S3-22RJ1 and S3-22RF1 are supplied in Tape & Reel (TR) packaging and use the identical 6327 J-Lead package with matching physical dimensions.

Q: Do these parts have the same thermal characteristics?

A: Yes. Both parts share identical temperature coefficient (±20ppm/°C) and operating temperature range (-55°C ~ 275°C).

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH affected, and carry identical moisture sensitivity level (MSL 1 - Unlimited).
