RSF2JB150R Equivalent & Substitute Parts

Part Overview

The RSF2JB150R is a 150 Ohms ±5% 2W through-hole resistor manufactured by Stackpole Electronics Inc. This metal oxide film axial resistor features flame retardant coating and safety design, operating across a temperature range of -55°C to 235°C. The part is currently active in production with ROHS3 compliance and is suitable for applications requiring reliable power dissipation in compact form factors. Substitute parts are identified when packaging configurations differ or when alternative series offerings provide equivalent electrical performance with identical core specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB150R is determined by matching the following core electrical and mechanical parameters: resistance value (150 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), axial package configuration, and two-terminal design. Packaging format (bulk versus cut tape) does not affect electrical equivalence. Physical dimensions may vary between series offerings while maintaining functional compatibility in standard through-hole applications. All substitute parts must maintain ROHS3 compliance and equivalent safety certifications.

Parameter Comparison

Engineering Selection Recommendations

RSF2JT150R serves as a direct electrical equivalent to RSF2JB150R with identical electrical specifications and physical dimensions. The primary distinction is packaging format: RSF2JT150R is supplied in cut tape configuration rather than bulk, making it suitable for automated assembly processes. Both parts maintain equivalent performance characteristics and compliance certifications.

RSMF2JT150R is a manufacturer-recommended alternative from the RSMF series, offering identical electrical performance with a more compact physical footprint (4.50mm x 11.00mm versus 5.50mm x 15.00mm). This series features flame proof construction compared to the flame retardant coating of the RSF series. Selection of RSMF2JT150R is appropriate for space-constrained applications where the reduced dimensions provide design advantages without compromising electrical or thermal performance. All three parts maintain active production status and full ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT150R be used as a direct replacement for RSF2JB150R? A: Yes. RSF2JT150R is electrically and mechanically equivalent to RSF2JB150R. Both parts share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. The difference is packaging format: RSF2JT150R is supplied in cut tape while RSF2JB150R is supplied in bulk.

Q: What is the difference between RSF2JB150R and RSMF2JT150R? A: Both parts are electrically equivalent with 150 Ohms resistance, ±5% tolerance, and 2W power rating. The RSMF2JT150R has a smaller physical footprint (4.50mm x 11.00mm versus 5.50mm x 15.00mm) and features flame proof construction instead of flame retardant coating. RSMF2JT150R is supplied in cut tape packaging.

Q: Are all three parts ROHS3 compliant? A: Yes. RSF2JB150R, RSF2JT150R, and RSMF2JT150R are all ROHS3 compliant and maintain equivalent environmental compliance certifications.

Q: Which part should I select for automated assembly? A: RSF2JT150R or RSMF2JT150R are both supplied in cut tape packaging suitable for automated pick-and-place assembly. RSF2JB150R in bulk packaging is intended for manual assembly or tape-and-reel conversion processes.

Q: Can RSMF2JT150R be used in applications with space constraints? A: Yes. RSMF2JT150R provides the same electrical performance as RSF2JB150R and RSF2JT150R in a more compact axial form factor, making it suitable for designs with limited board space.
