Substitute Part Grouping Explanation

Substitute parts for the RSF2JB200R are classified based on the following substitution criteria:

Direct Equivalent (Packaging Variant): RSF2JT200R maintains identical electrical specifications (200 Ohms, ±5%, 2W, metal oxide film composition) and mechanical dimensions. The substitution is valid based on matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The difference is packaging format (Cut Tape versus Bulk).

Manufacturer Recommended Substitute (Performance Upgrade): RSMF2JT200R provides equivalent electrical performance with enhanced flame proof safety features compared to flame retardant coating. Physical dimensions are reduced (0.177" Dia x 0.433" L versus 0.217" Dia x 0.591" L), maintaining the same 2W power rating, 200 Ohms resistance, and ±5% tolerance. This part is suitable for space-constrained applications.

Upgrade Option (Higher Power Rating): RSMF3JT200R increases the power rating to 3W while maintaining all other electrical parameters (200 Ohms, ±5%, metal oxide film, ±200ppm/°C, -55°C ~ 235°C). This part is applicable when higher power dissipation capability is required within the same resistance and tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

RSF2JT200R is the direct equivalent for applications requiring identical form factor and electrical performance. Both parts are ROHS3 compliant and active in production. Selection is based on packaging availability and supply chain requirements.

RSMF2JT200R is the manufacturer-recommended substitute, offering enhanced flame proof safety features with reduced physical dimensions. This part is suitable for designs where space optimization is beneficial without compromising electrical specifications. The smaller form factor (4.50mm x 11.00mm) accommodates compact PCB layouts while maintaining 2W power dissipation.

RSMF3JT200R is selected when circuit design requires higher power dissipation capability. The 3W rating provides additional thermal margin for applications operating at elevated ambient temperatures or with sustained current flow. All electrical parameters remain compatible with the original 200 Ohms, ±5% specification.

All substitute parts maintain ROHS3 compliance and active production status, ensuring long-term availability and regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT200R be used as a direct replacement for RSF2JB200R?

A: Yes. RSF2JT200R is electrically and mechanically equivalent to RSF2JB200R. Both parts have identical resistance (200 Ohms), tolerance (±5%), power rating (2W), physical dimensions (5.50mm x 15.00mm), and operating temperature range (-55°C ~ 235°C). The difference is packaging format: RSF2JB200R is supplied in bulk, while RSF2JT200R is supplied in cut tape.

Q: What is the advantage of RSMF2JT200R over RSF2JB200R?

A: RSMF2JT200R provides enhanced flame proof safety features compared to the flame retardant coating of RSF2JB200R. Additionally, RSMF2JT200R has a smaller physical footprint (4.50mm x 11.00mm versus 5.50mm x 15.00mm), making it suitable for space-constrained PCB designs. Electrical specifications remain identical.

Q: When should RSMF3JT200R be selected instead of RSF2JB200R?

A: RSMF3JT200R is selected when the circuit requires higher power dissipation capability. The 3W rating provides additional thermal margin compared to the 2W rating of RSF2JB200R. All other electrical parameters (resistance, tolerance, temperature coefficient, operating temperature) remain identical, ensuring circuit compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RSF2JT200R, RSMF2JT200R, and RSMF3JT200R are all ROHS3 compliant, matching the compliance status of RSF2JB200R.

Q: Can substitute parts be used interchangeably in existing designs?

A: RSF2JT200R and RSF2JB200R are fully interchangeable electrically and mechanically. RSMF2JT200R is interchangeable electrically but has reduced physical dimensions, which may require PCB layout verification. RSMF3JT200R is electrically interchangeable but provides higher power rating; no design changes are required for this upgrade.
