Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB330R is determined by matching the following critical parameters: resistance value (330 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), package type (axial), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), and compliance certifications (ROHS3, REACH unaffected).

The identified substitutes maintain these core electrical and mechanical specifications. Packaging format variations (bulk versus cut tape) do not affect electrical performance or circuit compatibility. Physical dimension differences within the axial package category are noted but do not preclude functional substitution in standard through-hole applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full compliance with ROHS3 and REACH requirements. RSF2JT330R provides direct electrical and dimensional equivalence to RSF2JB330R with identical specifications; the difference is packaging format (cut tape versus bulk). RSMF2JT330R is manufacturer-recommended and maintains all critical electrical parameters with identical temperature performance; however, physical dimensions are reduced (4.50mm x 11.00mm versus 5.50mm x 15.00mm). Selection between RSF2JT330R and RSMF2JT330R depends on available board space and mechanical clearance requirements. All three parts are suitable for applications requiring 330 Ohm, 2W, ±5% tolerance resistors within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT330R replace RSF2JB330R in my circuit? A: Yes. RSF2JT330R is electrically and mechanically identical to RSF2JB330R. The only difference is packaging format (cut tape versus bulk). Both parts have identical resistance, tolerance, power rating, temperature coefficient, and operating range.

Q: What is the difference between RSF2JB330R and RSMF2JT330R? A: Both parts are 330 Ohm, 2W, ±5% metal oxide film resistors with identical electrical performance. The primary difference is physical size: RSMF2JT330R is smaller (4.50mm x 11.00mm) compared to RSF2JB330R (5.50mm x 15.00mm). RSMF2JT330R is the manufacturer-recommended option.

Q: Are there any compliance differences between these substitutes? A: No. All three parts are ROHS3 compliant and REACH unaffected. They share identical regulatory status and certifications.

Q: Can I use RSMF2JT330R if my PCB layout was designed for RSF2JB330R? A: RSMF2JT330R has smaller physical dimensions. Verify that your PCB layout provides sufficient clearance for the reduced size (4.50mm diameter versus 5.50mm). If space is constrained, the smaller form factor may be advantageous. If your design requires the original dimensions, use RSF2JT330R instead.

Q: Which substitute should I choose for new designs? A: RSMF2JT330R is the manufacturer-recommended part and offers the advantage of a more compact form factor while maintaining all electrical specifications. Use this part for new designs unless specific space or mechanical constraints require the larger RSF2JB330R or RSF2JT330R dimensions.
