Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JB15K0 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 15 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 235°C
• Termination count: 2

Allowed Variations:

• Packaging format (Bulk vs. Cut Tape)
• Physical dimensions (within axial package constraints)
• Flame retardant vs. flame proof coating classification
• Series designation (RSF vs. RSMF)

All identified substitutes maintain identical electrical performance and compliance certifications while differing only in packaging delivery method or enhanced safety feature classification.

Parameter Comparison

Engineering Selection Recommendations

RSF2JT15K0 serves as a direct electrical equivalent to RSF2JB15K0, differing only in packaging format (Cut Tape vs. Bulk). Both parts maintain identical physical dimensions, electrical specifications, and compliance certifications. Selection between these two is determined by procurement requirements and assembly process compatibility.

RSMF2JT15K0 is the manufacturer-recommended alternative, offering enhanced flame proof safety classification compared to the flame retardant coating of the original part. This part features a more compact axial package (4.50mm x 11.00mm vs. 5.50mm x 15.00mm) while maintaining all electrical parameters. The RSMF2JT15K0 is suitable for applications where space constraints or enhanced thermal safety requirements justify the dimensional change. All three parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT15K0 be used as a direct replacement for RSF2JB15K0?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The only difference is packaging format: RSF2JB15K0 is supplied in Bulk, while RSF2JT15K0 is supplied in Cut Tape. Physical dimensions and performance characteristics are identical.

Q: What is the difference between RSF2JB15K0 and RSMF2JT15K0?

A: Both parts share identical electrical specifications (15 kOhms ±5%, 2W, ±200ppm/°C, -55°C ~ 235°C). The RSMF2JT15K0 differs in two aspects: (1) Enhanced safety classification with flame proof coating instead of flame retardant, and (2) Compact axial dimensions of 4.50mm x 11.00mm compared to 5.50mm x 15.00mm. The RSMF2JT15K0 is supplied in Cut Tape format.

Q: Are there physical space considerations when substituting RSMF2JT15K0 for RSF2JB15K0?

A: Yes. The RSMF2JT15K0 has a smaller axial package (4.50mm diameter x 11.00mm length) compared to RSF2JB15K0 (5.50mm diameter x 15.00mm length). Verify that PCB layout and component spacing accommodate the dimensional difference before substitution.

Q: Do all three parts meet the same compliance standards?

A: Yes. RSF2JB15K0, RSF2JT15K0, and RSMF2JT15K0 are all ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility across applications.

Q: Which substitute should be selected for new designs?

A: Selection depends on procurement and assembly requirements. For equivalent performance with standard packaging, use RSF2JT15K0. For applications requiring enhanced flame proof safety classification and compact dimensions, use RSMF2JT15K0. All three parts are active in production and suitable for new designs.
