RSF2JTR620 Equivalent & Substitute Parts

Part Overview

The RSF2JTR620 is a 620 mOhms ±5% 2W through-hole axial resistor manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame retardant coating and safety characteristics, designed for applications requiring precision current sensing and power dissipation in the 2W range. The part is currently active in production with 909 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JTR620 is determined by the following critical parameters:

• Resistance value: 620 mOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C to 235°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Termination count: 2 (exact match required)
• Regulatory compliance: ROHS3 Compliant (exact match required)

The RSMF2JTR620 meets all substitution criteria. Packaging format differs (Cut Tape versus Tape & Reel), and physical dimensions vary slightly, but electrical performance and functional characteristics remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF2JTR620 and RSMF2JTR620 are active production parts from Stackpole Electronics Inc with identical electrical specifications and ROHS3 compliance. Selection between these parts depends on packaging and inventory requirements:

The RSF2JTR620 in Tape & Reel format is suitable for high-volume automated assembly operations. The RSMF2JTR620 in Cut Tape format accommodates lower-volume applications or manual assembly processes. Both parts satisfy the same electrical and thermal performance requirements for 620 mOhms 2W axial resistor applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JTR620 replace RSF2JTR620 in my circuit?

A: Yes. Both parts have identical electrical specifications: 620 mOhms resistance, ±5% tolerance, 2W power rating, ±200ppm/°C temperature coefficient, and -55°C to 235°C operating range. The difference is packaging format only.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging provides components on tape segments, suitable for manual assembly or lower-volume production.

Q: Are the physical dimensions identical?

A: No. RSF2JTR620 measures 0.217" diameter × 0.591" length (5.50mm × 15.00mm). RSMF2JTR620 measures 0.177" diameter × 0.433" length (4.50mm × 11.00mm). Both are axial through-hole components with equivalent electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSF2JTR620 and RSMF2JTR620 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which part should I select for new designs?

A: Selection depends on assembly method and volume. For automated assembly, use RSF2JTR620 (Tape & Reel). For manual assembly or prototyping, use RSMF2JTR620 (Cut Tape). Both deliver identical circuit performance.
