RSF2JB510R Equivalent & Substitute Parts

Part Overview

The RSF2JB510R is a 510 Ohms ±5% 2W through-hole resistor manufactured by Stackpole Electronics Inc. This axial metal oxide film resistor features flame retardant coating and safety design, operating across -55°C to 235°C. The part is Active status and ROHS3 compliant. Substitute parts are identified when packaging format or series variants meet identical electrical and mechanical specifications, enabling procurement flexibility while maintaining circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB510R is determined by matching the following critical parameters: resistance value (510 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), axial package configuration, and compliance certifications (ROHS3). Variations in packaging format (Bulk, Tape & Reel, Cut Tape) and series designation (RSF, RSMF) do not affect electrical performance or mechanical compatibility in through-hole applications. Physical dimensions may vary within the axial form factor while maintaining functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RSF2JB510R, RSF2JT510R, and RSMF2JT510R—are Active status products manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance. Selection between these equivalents is determined by procurement and assembly requirements rather than electrical performance. RSF2JB510R in Bulk packaging suits manual assembly or small-batch applications. RSF2JT510R in Tape & Reel format supports automated pick-and-place assembly with standard reel handling. RSMF2JT510R in Cut Tape format provides flexibility for mixed-component orders or partial reel requirements. All parts deliver identical electrical characteristics across the specified operating temperature range and maintain equivalent reliability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT510R replace RSF2JB510R in production assembly? A: Yes. Both parts are electrically and mechanically equivalent 510 Ohms ±5% 2W axial resistors. The difference is packaging format: RSF2JB510R is supplied in Bulk, while RSF2JT510R is supplied in Tape & Reel. Selection depends on assembly process requirements, not circuit performance.

Q: What is the difference between RSF and RSMF series designations? A: Both series are metal oxide film axial resistors with identical electrical specifications for this 510 Ohm 2W application. The RSMF series features flame-proof coating compared to flame-retardant coating in the RSF series. All three parts meet the same operating temperature range and compliance standards.

Q: Are physical dimensions identical across all three parts? A: Physical dimensions vary slightly. RSF2JB510R and RSF2JT510R measure 0.217" Dia x 0.591" L (5.50mm x 15.00mm). RSMF2JT510R measures 0.177" Dia x 0.433" L (4.50mm x 11.00mm). Both form factors are axial and compatible with standard through-hole PCB layouts, though board spacing should be verified for the smaller RSMF variant.

Q: Which part should be selected for high-volume automated assembly? A: RSF2JT510R or RSMF2JT510R are preferred for automated assembly due to Tape & Reel and Cut Tape packaging formats, which integrate with standard pick-and-place equipment. RSF2JB510R Bulk packaging is suitable for manual assembly or lower-volume production.

Q: Do all three parts carry the same compliance certifications? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Compliance status is identical across all substitute options.
