Substitute Part Grouping Explanation

The RSMF3JB33K0 has one identified substitute: RSMF3JT33K0. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and share identical electrical and mechanical specifications. The substitution is valid based on the following matching parameters:

• Resistance value: 33 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package/Case: Axial
• Physical dimensions: 0.217" Dia x 0.591" L (5.50mm x 15.00mm)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Features: Flame Proof, Safety
• RoHS compliance: ROHS3 Compliant

The only difference between these parts is the packaging format: RSMF3JB33K0 is supplied in Bulk packaging, while RSMF3JT33K0 is supplied in Cut Tape (CT) packaging.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF3JB33K0 and RSMF3JT33K0 are Active status components from Stackpole Electronics Inc with identical electrical performance and mechanical compatibility. Selection between these parts depends on procurement and assembly requirements:

• RSMF3JB33K0 (Bulk packaging) is suitable for high-volume applications where components are supplied in loose form for manual or bulk handling processes.
• RSMF3JT33K0 (Cut Tape packaging) is suitable for automated assembly operations requiring tape-and-reel or cut-tape feeding systems.

Both parts maintain ROHS3 compliance and are REACH unaffected, meeting regulatory requirements for industrial and commercial applications. The choice between bulk and cut-tape packaging does not affect electrical performance or thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can RSMF3JT33K0 replace RSMF3JB33K0 in my circuit?

A: Yes. Both parts have identical electrical specifications (33 kOhms ±5%, 3W), composition (metal oxide film), temperature characteristics (±200ppm/°C, -55°C to 235°C), and physical dimensions (0.217" Dia x 0.591" L). The difference is packaging format only.

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

A: Bulk packaging supplies components loose in a container, suitable for manual assembly or bulk handling. Cut Tape (CT) packaging supplies components on adhesive tape in specified quantities, designed for automated pick-and-place assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF3JB33K0 and RSMF3JT33K0 are ROHS3 compliant and REACH unaffected.

Q: Do these resistors have the same thermal performance?

A: Yes. Both parts have identical temperature coefficients (±200ppm/°C) and operating temperature ranges (-55°C to 235°C), ensuring equivalent thermal stability in circuit applications.

Q: Can I use these parts interchangeably in PCB assembly?

A: Electrical and mechanical interchangeability is complete. Assembly process compatibility depends on your equipment: bulk packaging requires manual placement, while cut-tape packaging integrates with automated assembly systems.
