Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB200R is determined by strict equivalence across the following critical parameters: resistance value (200 Ohms), tolerance (±5%), power rating (2W), composition (metal oxide film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 235°C), package type (axial), and regulatory compliance (ROHS3). Packaging format (bulk versus cut tape) does not affect electrical or mechanical compatibility. Physical dimensions may vary within the axial package category while maintaining functional interchangeability. All identified substitutes meet these core requirements.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers are active products manufactured by Stackpole Electronics Inc and maintain ROHS3 compliance. RSMF2JB200R and RSMF2JT200R are electrically and mechanically identical, differing only in packaging format (bulk versus cut tape). Selection between these two depends on procurement and assembly requirements. RSF2JT200R is functionally equivalent across all critical electrical parameters but features a larger physical envelope (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) and incorporates flame retardant coating rather than flame proof construction. RSF2JT200R is suitable for applications where the larger form factor and flame retardant characteristics are acceptable. All parts maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT200R be used as a direct replacement for RSMF2JB200R? A: Yes. Both parts are electrically and mechanically identical 200 Ohms ±5% 2W metal oxide film axial resistors. The difference is packaging format: RSMF2JB200R is supplied in bulk, while RSMF2JT200R is supplied in cut tape. No circuit modifications are required.

Q: What is the difference between RSMF2JT200R and RSF2JT200R? A: Both are 200 Ohms ±5% 2W metal oxide film axial resistors with identical electrical specifications. The primary differences are physical dimensions (RSF2JT200R is larger: 0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) and surface treatment (RSF2JT200R features flame retardant coating; RSMF2JT200R features flame proof construction). Electrical performance is equivalent.

Q: Are all three parts ROHS3 compliant? A: Yes. RSMF2JB200R, RSMF2JT200R, and RSF2JT200R are all ROHS3 compliant.

Q: Can RSF2JT200R be used in a circuit designed for RSMF2JB200R? A: Electrically, yes. All electrical parameters are identical. However, the larger physical dimensions of RSF2JT200R (0.217" Dia x 0.591" L) must be accommodated in the PCB layout. Verify that the larger form factor does not create mechanical interference or spacing conflicts in your design.

Q: What is the operating temperature range for all substitute parts? A: All three parts operate across -55°C to 235°C with a temperature coefficient of ±200ppm/°C.
