Equivalent & Substitute Parts for S2-3KJ8

Part Overview

The S2-3KJ8 is a 3 kOhms ±5% 1W wirewound chip resistor manufactured by Riedon in the 2615 J-Lead package. This component is designed for current sensing applications and features flame-proof, moisture-resistant, and pulse-withstanding characteristics. The part is Active in product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Finding equivalent or substitute parts may be necessary due to inventory constraints, application-specific tolerance requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the S2-3KJ8 is determined by the following critical parameters:

• Resistance Value: Must remain 3 kOhms
• Power Rating: Must remain 1W
• Package / Case: Must remain 2615 J-Lead
• Composition: Must remain Wirewound
• Operating Temperature Range: Must remain -55°C ~ 275°C
• Temperature Coefficient: Must remain ±20ppm/°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The S2-3KF1 qualifies as a substitute part because it maintains all critical parameters while offering improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

The S2-3KF1 is a direct substitute for the S2-3KJ8 with identical mechanical and thermal characteristics. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. The primary distinction is tolerance specification: the S2-3KF1 provides ±1% tolerance compared to the S2-3KJ8's ±5% tolerance. Selection between these parts should be based on circuit tolerance requirements and application-specific accuracy needs. Both parts are Active in product status with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can S2-3KF1 be used as a direct replacement for S2-3KJ8?

A: Yes. Both parts share identical resistance value (3 kOhms), power rating (1W), package type (2615 J-Lead), operating temperature range (-55°C ~ 275°C), and temperature coefficient (±20ppm/°C). The S2-3KF1 offers tighter tolerance (±1% versus ±5%).

Q: What is the primary difference between these parts?

A: The tolerance specification differs. S2-3KJ8 has ±5% tolerance, while S2-3KF1 has ±1% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts compliant with environmental standards?

A: Yes. Both S2-3KJ8 and S2-3KF1 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH Affected status.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts measure 0.260" L x 0.154" W (6.60mm x 3.90mm) with a maximum seated height of 0.142" (3.60mm) in the 2615 J-Lead package.

Q: Which part should I select for my application?

A: Selection depends on circuit tolerance requirements. Use S2-3KJ8 for applications with ±5% tolerance acceptance. Use S2-3KF1 for applications requiring tighter ±1% tolerance specification.
