Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S5-0R05J8 are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 50 mOhms (exact match required)
• Power rating: 4W (exact match required)
• Composition: Wirewound (exact match required)

Mechanical Parameters (Critical):

• Package / Case: 8230 J-Lead (exact match required)
• Physical dimensions: 0.819" L x 0.296" W, height 0.319" max (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance Parameters (Critical):

• Operating temperature range: -55°C ~ 275°C (exact match required)
• RoHS3 Compliance (required)
• REACH Affected status (required)

Tolerance Variance: Tolerance may vary from ±5% to tighter specifications (±1%) while maintaining full substitutability, as tighter tolerance represents improved performance without circuit impact.

Parameter Comparison

Engineering Selection Recommendations

The S5-0R05F1 qualifies as a direct substitute for the S5-0R05J8 based on identical electrical, mechanical, and environmental specifications. The primary distinction is tolerance specification: S5-0R05F1 provides ±1% tolerance compared to ±5% tolerance of the main part.

Both parts maintain Active product status and full RoHS3 and REACH compliance. Selection between these parts depends on application tolerance requirements. Where circuit design permits ±5% tolerance, either part is suitable. Where tighter tolerance control is required, S5-0R05F1 provides enhanced precision without modification to PCB layout, thermal management, or circuit operation.

Both parts are supplied in Tape & Reel packaging and maintain identical MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can S5-0R05F1 replace S5-0R05J8 in existing designs?

A: Yes. S5-0R05F1 is mechanically and electrically compatible with S5-0R05J8. Identical package, dimensions, power rating, and operating temperature range ensure direct substitution without PCB modification or thermal redesign.

Q: What is the tolerance difference between these parts?

A: S5-0R05J8 specifies ±5% tolerance, while S5-0R05F1 specifies ±1% tolerance. Both measure 50 mOhms nominal resistance. The tighter tolerance of S5-0R05F1 provides improved measurement accuracy in current sense applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both S5-0R05J8 and S5-0R05F1 are RoHS3 Compliant and REACH Affected, meeting current environmental and regulatory requirements.

Q: Do these parts have moisture sensitivity concerns?
