Key Parameters

Substitute Part Grouping Explanation

Substitution of the RSF2JB2K40 is determined by the following critical parameters:

• Resistance value: 2.4 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Termination count: 2
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The RSF2JB2K40 has one identified substitute part: RSF2JT2K40. This substitute maintains identical electrical specifications and physical dimensions. The primary difference is packaging format: RSF2JB2K40 is supplied in Bulk packaging, while RSF2JT2K40 is supplied in Cut Tape (CT) packaging. Both parts are from the same RSF series and manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Both RSF2JB2K40 and RSF2JT2K40 are active production parts from Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance.

RSF2JB2K40 in Bulk packaging is suitable for high-volume manufacturing environments with integrated tape-to-board assembly processes. RSF2JT2K40 in Cut Tape (CT) packaging is appropriate for applications requiring smaller quantity procurement or manual assembly operations.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical temperature coefficient (±200ppm/°C) and operating range (-55°C to 235°C) ensure consistent performance across thermal cycling conditions.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT2K40 be used as a direct replacement for RSF2JB2K40?

A: Yes. Both parts have identical resistance (2.4 kOhms), tolerance (±5%), power rating (2W), composition (metal oxide film), physical dimensions (0.217" Dia x 0.591" L), and electrical characteristics. The only difference is packaging format: Bulk versus Cut Tape.

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

A: Bulk packaging supplies loose components suitable for high-volume automated assembly. Cut Tape (CT) packaging provides components on carrier tape in specified quantities, typically used for smaller production runs or manual assembly.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts have identical temperature coefficients (±200ppm/°C) and operating temperature ranges (-55°C to 235°C). Thermal performance is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSF2JB2K40 and RSF2JT2K40 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should be selected for new designs?

A: Selection depends on manufacturing process and supply chain strategy. Both parts are active production items. Choose based on packaging compatibility with your assembly process and inventory management requirements.
