Substitute Part Grouping Explanation

Substitution eligibility for the RSF2JT2K70-C3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.217" Dia × 0.591" L (5.50mm × 15.00mm)
• Termination count: 2
• RoHS compliance: ROHS3 Compliant

The RSF2JB2K70 meets all mandatory parameters and qualifies as a parametric equivalent. The primary distinction between the main part and this substitute is the flame-protection feature: RSF2JT2K70-C3 incorporates flame-proof construction, while RSF2JB2K70 features flame-retardant coating. Both provide safety certification and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF2JT2K70-C3 and RSF2JB2K70 are active production components from Stackpole Electronics Inc and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application-specific flame-protection requirements:

RSF2JT2K70-C3 is appropriate for applications where flame-proof construction is specified or required by design standards.

RSF2JB2K70 is appropriate for applications where flame-retardant coating meets the flame-protection requirement.

Both parts share identical electrical characteristics, physical dimensions, and thermal performance specifications. Substitution is electrically and mechanically valid when the flame-protection distinction does not impose a design constraint.

Frequently Asked Questions (FAQ)

Q: Can RSF2JB2K70 be used as a direct replacement for RSF2JT2K70-C3?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical resistance (2.7 kOhms), tolerance (±5%), power rating (2W), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 235°C), and physical dimensions (0.217" Dia × 0.591" L). The difference is in flame protection: RSF2JT2K70-C3 is flame-proof, while RSF2JB2K70 has flame-retardant coating. Substitution is valid if your application does not specifically require flame-proof construction.

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

A: Flame-proof construction (RSF2JT2K70-C3) and flame-retardant coating (RSF2JB2K70) are distinct flame-protection features. The specific performance differences are determined by the respective safety certifications. Selection depends on your application's flame-protection requirements.

Q: Are the physical dimensions identical?

A: Yes. Both RSF2JT2K70-C3 and RSF2JB2K70 have identical dimensions of 0.217" Dia × 0.591" L (5.50mm × 15.00mm), ensuring compatibility with the same PCB layouts and mechanical assemblies.

Q: Do both parts meet RoHS compliance?

A: Yes. Both RSF2JT2K70-C3 and RSF2JB2K70 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the temperature coefficient specification?

A: Both parts have a temperature coefficient of ±200ppm/°C, indicating equivalent thermal stability across the operating temperature range of -55°C to 235°C.

Q: Are there inventory differences between the two parts?

A: Yes. RSF2JT2K70-C3 has 753 units in stock, while RSF2JB2K70 has 639 units in stock. Inventory levels may influence component selection when lead time is a consideration.
