Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF3JB15R0 is determined by the following critical parameters:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Package: Axial through-hole (exact match required)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The ROX3SJ15R from TE Connectivity Passive Product meets all core electrical and mechanical requirements. Both parts share identical resistance, tolerance, power rating, and axial package configuration. Both are ROHS3 compliant and maintain metal oxide film construction suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF3JB15R0 and ROX3SJ15R are active production parts with ROHS3 compliance. Selection between these parts should be based on the following factors:

The RSF3JB15R0 offers a wider operating temperature range (-55°C to 235°C) and lower temperature coefficient (±200ppm/°C), making it suitable for applications requiring extended thermal performance. The ROX3SJ15R provides equivalent electrical performance with a narrower operating range (-55°C to 200°C) and higher temperature coefficient (±350ppm/°C). Physical dimensions differ slightly, with the ROX3SJ15R being more compact. Both parts maintain identical resistance, tolerance, power rating, and axial package configuration required for direct circuit substitution.

Frequently Asked Questions (FAQ)

Q: Can ROX3SJ15R replace RSF3JB15R0 in all applications?

A: ROX3SJ15R meets the core electrical specifications (15 Ohms, ±5%, 3W, metal oxide film, axial package). However, applications operating above 200°C or requiring the lower temperature coefficient of ±200ppm/°C should retain the RSF3JB15R0.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use axial through-hole packaging with 2 terminations. The ROX3SJ15R is slightly more compact (5.50mm diameter vs. 6.00mm, 16.00mm length vs. 17.50mm). PCB layout and spacing should accommodate the smaller dimensions of the ROX3SJ15R without issue.

Q: Do both parts meet the same regulatory requirements?

A: Both RSF3JB15R0 and ROX3SJ15R are ROHS3 compliant with EAR99 ECCN classification and identical HTSUS codes (8533.21.0090).

Q: What is the temperature coefficient difference and when does it matter?

A: The RSF3JB15R0 has ±200ppm/°C while ROX3SJ15R has ±350ppm/°C. In precision circuits requiring tight resistance stability across temperature variations, the lower coefficient of the RSF3JB15R0 is preferable.

Q: Are there packaging format differences?

A: RSF3JB15R0 is supplied in Bulk packaging, while ROX3SJ15R is supplied in Cut Tape (CT) format. This affects procurement and handling but does not impact electrical or mechanical compatibility.
