Key Parameters

Substitute Part Grouping Explanation

Substitution for the RSF3JB36K0 is determined by matching the following critical parameters:

• Resistance value: 36 kOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Metal Oxide Film
• Package: Axial through-hole
• Operating temperature range: minimum -55°C to maximum 235°C or higher
• RoHS compliance: ROHS3 Compliant

Substitute parts must maintain these electrical and mechanical specifications. Variations in packaging format (Bulk, Tape & Reel, Cut Tape), physical dimensions within the axial envelope, temperature coefficient, and enhanced safety features (flame proof vs. flame retardant) are permitted within the substitution criteria for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical substitution criteria for 36 kOhms ±5% 3W axial metal oxide film resistors. Selection between RSF3JB36K0, RSMF3JT36K0, and ROX3SJ36K should be based on:

• Packaging format requirements: RSF3JB36K0 is supplied in Bulk; RSMF3JT36K0 in Tape & Reel; ROX3SJ36K in Cut Tape
• Temperature coefficient tolerance: RSF3JB36K0 and RSMF3JT36K0 specify ±200ppm/°C; ROX3SJ36K specifies ±350ppm/°C
• Maximum operating temperature: RSF3JB36K0 and RSMF3JT36K0 operate to 235°C; ROX3SJ36K operates to 200°C
• Safety feature enhancement: RSMF3JT36K0 and ROX3SJ36K feature flame proof construction; RSF3JB36K0 features flame retardant coating
• Inventory availability: ROX3SJ36K has the highest stock level at 15,314 pieces

All parts are ROHS3 compliant and Active in product status.

Frequently Asked Questions (FAQ)

Q: Can RSF3JB36K0 be directly replaced with RSMF3JT36K0?

A: Yes. Both parts share identical electrical specifications (36 kOhms ±5%, 3W, ±200ppm/°C, -55°C to 235°C operating range) and metal oxide film composition in axial package. The primary difference is packaging format: RSF3JB36K0 is supplied in Bulk, while RSMF3JT36K0 is supplied in Tape & Reel.

Q: Can RSF3JB36K0 be replaced with ROX3SJ36K?

A: Yes, with design consideration. ROX3SJ36K meets the core electrical requirements (36 kOhms ±5%, 3W, axial metal oxide film). However, ROX3SJ36K has a higher temperature coefficient (±350ppm/°C vs. ±200ppm/°C) and a lower maximum operating temperature (200°C vs. 235°C). Applications requiring operation above 200°C or tighter temperature stability should use RSF3JB36K0 or RSMF3JT36K0.

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

A: Both are safety features in resistor construction. Flame retardant coating (RSF3JB36K0) resists ignition and slows flame propagation. Flame proof construction (RSMF3JT36K0, ROX3SJ36K) provides enhanced fire resistance. Selection depends on application safety requirements.

Q: Are all three parts ROHS3 compliant?

A: Yes. RSF3JB36K0, RSMF3JT36K0, and ROX3SJ36K are all ROHS3 compliant.

Q: What packaging formats are available?

A: RSF3JB36K0 is supplied in Bulk; RSMF3JT36K0 in Tape & Reel (TR); ROX3SJ36K in Cut Tape (CT). Packaging selection depends on assembly process and volume requirements.
