All parts are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can RSF2JA47K0 or RSF2JT47K0 be used as direct replacements for RSF2JB47K0?

A: Yes. Both parts are electrically and mechanically identical to RSF2JB47K0. The only difference is packaging format (Cut Tape vs. Bulk). They share identical resistance, tolerance, power rating, composition, temperature coefficient, and operating temperature range. Physical dimensions and axial mounting are unchanged.

Q: What is the difference between RSF2JB47K0 and RSMF2JT47K0?

A: Both parts have identical electrical specifications (47 kOhms ±5%, 2W, Metal Oxide Film, ±200ppm/°C, -55°C ~ 235°C). The RSMF2JT47K0 features flame proof safety design versus flame retardant coating on RSF2JB47K0. Physical dimensions differ: RSMF2JT47K0 is 4.50mm x 11.00mm compared to 5.50mm x 15.00mm for RSF2JB47K0. Both maintain axial through-hole compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RSF2JA47K0, RSF2JT47K0, and RSMF2JT47K0 are all ROHS3 compliant and REACH unaffected, matching the compliance status of RSF2JB47K0.

Q: Which substitute part has the best availability?

A: RSMF2JT47K0 has the highest inventory at 9802 Pcs. RSF2JA47K0 follows with 3409 Pcs, and RSF2JT47K0 has 1710 Pcs available.

Q: Can RSMF2JT47K0 be used in applications requiring the exact same physical dimensions as RSF2JB47K0?

A: No. RSMF2JT47K0 has reduced dimensions (4.50mm x 11.00mm vs. 5.50mm x 15.00mm). It is suitable for space-constrained applications while maintaining electrical equivalence and axial through-hole mounting. Verify PCB layout compatibility before substitution.
