Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three core parameters: resistance value, tolerance, and composition. All identified substitutes maintain 33 kOhms ±5% metal oxide film construction. Variations occur in packaging format (Bulk, Cut Tape, Tape & Reel), power rating (2W or 3W), series designation (RSF or RSMF), and physical dimensions. The RSF2JT33K0 provides direct electrical equivalence with alternative packaging. The RSMF series parts offer enhanced flame proof features with modified dimensions and packaging configurations.

Parameter Comparison

Engineering Selection Recommendations

RSF2JT33K0 serves as the direct electrical equivalent with identical specifications and dimensions, differing only in packaging format (Cut Tape versus Bulk). Selection depends on procurement and assembly requirements.

RSMF3JT33K0 provides upgraded power handling at 3W while maintaining all other electrical parameters. This part accommodates applications requiring higher power dissipation margins. Physical dimensions remain consistent with the main part.

RSMF2JT33K0 offers flame proof enhancement over flame retardant coating with reduced physical dimensions (4.50mm x 11.00mm versus 5.50mm x 15.00mm). This part is suitable for space-constrained applications requiring improved flame safety characteristics. Packaging format is Tape & Reel.

All substitute parts maintain ROHS3 compliance and identical temperature coefficient and operating range specifications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT33K0 replace RSF2JB33K0 directly? A: Yes. Both parts share identical electrical specifications (33 kOhms ±5%, 2W, metal oxide film) and physical dimensions. The difference is packaging format: RSF2JB33K0 is supplied in Bulk, while RSF2JT33K0 is supplied in Cut Tape. Direct substitution is valid for circuit performance.

Q: What is the difference between RSF and RSMF series? A: The RSF series features flame retardant coating, while the RSMF series features flame proof construction. Both meet safety requirements; RSMF provides enhanced flame safety performance. RSMF2JT33K0 also has reduced physical dimensions compared to RSF parts.

Q: When should RSMF3JT33K0 be selected over RSMF2JT33K0? A: RSMF3JT33K0 provides 3W power rating versus 2W in RSMF2JT33K0. Select the 3W variant when circuit analysis indicates power dissipation approaching or exceeding 2W limits, or when design margin requirements specify higher power headroom.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RSF2JB33K0, RSF2JT33K0, RSMF3JT33K0, and RSMF2JT33K0 are all ROHS3 compliant.

Q: What packaging formats are available? A: RSF2JB33K0 is supplied in Bulk. RSF2JT33K0 and RSMF3JT33K0 are supplied in Cut Tape. RSMF2JT33K0 is supplied in Tape & Reel. Selection depends on assembly process requirements and order quantities.

Q: Do dimension differences affect PCB layout? A: RSMF2JT33K0 has reduced dimensions (4.50mm x 11.00mm) compared to RSF series parts (5.50mm x 15.00mm). PCB footprint and lead spacing must accommodate the selected part. RSF2JT33K0 and RSMF3JT33K0 maintain identical dimensions to the main part.
