• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C

Mechanical Parameters (Must Match):

• Package type: Axial through-hole
• Number of terminations: 2

Allowed Variations:

• Packaging format (Bulk, Cut Tape)
• Physical dimensions (within axial form factor)
• Surface treatment (Flame Proof vs. Flame Retardant Coating)
• Series designation (RSMF vs. RSF)

All substitute parts listed maintain identical electrical specifications and are manufactured by Stackpole Electronics Inc under the same compliance framework.

Parameter Comparison

Engineering Selection Recommendations

RSMF2JT47K0 is the primary direct substitute for RSMF2JB47K0. Both parts share identical electrical specifications, physical dimensions, and flame-proof surface treatment. The only difference is packaging format: RSMF2JT47K0 is supplied in Cut Tape format with significantly higher inventory availability (9802 units vs. 703 units). Selection of this substitute is appropriate when tape packaging is compatible with assembly processes.

RSF2JA47K0 and RSF2JT47K0 are manufacturer-recommended alternatives from the RSF series. These parts maintain all electrical parameters and operating characteristics but feature flame-retardant coating instead of flame-proof construction and have larger physical dimensions (0.217" Dia x 0.591" L vs. 0.177" Dia x 0.433" L). Selection of RSF series parts is appropriate when PCB layout accommodates the larger form factor and flame-retardant coating meets application requirements. RSF2JA47K0 offers higher inventory (3409 units) compared to RSF2JT47K0 (1710 units).

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT47K0 replace RSMF2JB47K0 in existing designs?

A: Yes. RSMF2JT47K0 is a direct electrical and mechanical equivalent. The only difference is packaging format (Cut Tape vs. Bulk). If your assembly process accepts tape-packaged components, this substitution requires no design changes.

Q: What is the difference between RSMF and RSF series resistors?

A: Both series are 47 kOhm ±5% 2W metal oxide film resistors with identical electrical performance. The RSMF series features flame-proof construction with dimensions 0.177" Dia x 0.433" L. The RSF series features flame-retardant coating with larger dimensions 0.217" Dia x 0.591" L. Selection depends on PCB layout constraints and surface treatment requirements.

Q: Are the RSF2JA47K0 and RSF2JT47K0 parts interchangeable with each other?

A: Yes. RSF2JA47K0 and RSF2JT47K0 are electrically and mechanically identical. The difference is packaging format: RSF2JA47K0 is supplied in Cut Tape with higher inventory availability.

Q: Will using a larger RSF series resistor affect PCB layout?

A: The RSF series has larger physical dimensions (0.217" Dia x 0.591" L) compared to RSMF series (0.177" Dia x 0.433" L). PCB layout must accommodate this size difference. Verify that component spacing and trace routing allow for the larger form factor before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RSMF2JB47K0, RSMF2JT47K0, RSF2JA47K0, and RSF2JT47K0 are all ROHS3 compliant and REACH unaffected, ensuring regulatory compatibility across all substitution options.

Q: Which substitute part should I select for maximum inventory availability?

A: RSMF2JT47K0 offers the highest inventory with 9802 units in stock. This part is the direct equivalent to RSMF2JB47K0 with only packaging format differences.
