Substitute Part Grouping Explanation

Substitute parts for the RSF2JB12K0 are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

  • Identical resistance value: 12 kOhms
  • Identical tolerance: ±5%
  • Identical power rating: 2W
  • Identical composition: Metal Oxide Film
  • Identical package type: Axial
  • Identical temperature coefficient: ±200ppm/°C
  • Identical operating temperature range: -55°C ~ 235°C
  • Identical physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
  • Identical manufacturer: Stackpole Electronics Inc
  • Identical series: RSF

The RSF2JT12K0 qualifies as a direct substitute. The only difference between these parts is the packaging format: RSF2JB12K0 is supplied in Bulk packaging, while RSF2JT12K0 is supplied in Cut Tape (CT) packaging. Both parts are electrically and mechanically identical, with the same component specifications and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT12K0 be used as a direct replacement for RSF2JB12K0?

A: Yes. The RSF2JT12K0 is a direct substitute. All electrical parameters, mechanical dimensions, and performance characteristics are identical. The only difference is the packaging format (Cut Tape versus Bulk).

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

A: Bulk packaging supplies components in loose form, suitable for manual handling and high-volume applications. Cut Tape packaging supplies components on adhesive tape in continuous strips, optimized for automated pick-and-place assembly equipment.

Q: Are both parts compliant with current regulations?

A: Yes. Both RSF2JB12K0 and RSF2JT12K0 are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: Will switching from RSF2JB12K0 to RSF2JT12K0 require circuit design changes?

A: No. Both parts are electrically and mechanically identical. No circuit design modifications are required. The substitution affects only procurement and assembly processes.

Q: Are there any temperature or performance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C ~ 235°C) with the same temperature coefficient (±200ppm/°C) and power rating (2W).
