Substitute Part Grouping Explanation

Substitution of the RSF2JB15R0 is valid when the following core parameters remain constant:

• Resistance value: 15 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Package configuration: Axial through-hole
• Compliance: ROHS3 Compliant, REACH Unaffected

The RSMF2JT15R0 meets all substitution criteria. Differences in physical dimensions and packaging format (Cut Tape versus Bulk) do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The RSMF2JT15R0 is a valid substitute for the RSF2JB15R0 based on electrical equivalence and regulatory compliance. Both parts are manufactured by Stackpole Electronics Inc, maintain identical electrical specifications, and comply with ROHS3 and REACH requirements. The RSMF2JT15R0 features flame proof construction compared to the flame retardant coating of the RSF2JB15R0, representing an enhancement in safety characteristics. Selection between these parts should be based on packaging requirements and physical space constraints, as the RSMF2JT15R0 has a smaller physical footprint.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT15R0 be used in place of RSF2JB15R0 in existing designs?

A: Yes. Both parts share identical electrical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The primary consideration is physical dimensions and available board space.

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

A: Bulk packaging is supplied as loose components, while Cut Tape (CT) packaging provides components on adhesive tape in individual pockets. This affects handling, automation compatibility, and storage but does not impact electrical performance.

Q: Are there dimensional compatibility concerns?

A: The RSMF2JT15R0 is physically smaller (4.50mm x 11.00mm) compared to the RSF2JB15R0 (5.50mm x 15.00mm). In applications with tight space constraints, the smaller substitute may be advantageous. In applications requiring specific lead length or diameter, dimensional verification is necessary.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the RSF2JB15R0 and RSMF2JT15R0 are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements.

Q: What is the difference between flame retardant and flame proof?

A: Flame retardant coating slows flame propagation, while flame proof construction prevents flame propagation. The RSMF2JT15R0 offers enhanced fire safety characteristics.
