Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB30R0 is determined by strict equivalence in the following parameters:

• Resistance value: 30 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The RSF2JT30R0 meets all substitution criteria. Differences in physical dimensions (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L) and packaging format (Cut Tape versus Bulk) do not affect electrical performance or functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF2JB30R0 and RSF2JT30R0 are active production parts from Stackpole Electronics Inc with identical electrical specifications and full regulatory compliance. Selection between these parts should be based on:

• Packaging requirements: Bulk packaging for RSMF2JB30R0 versus Cut Tape format for RSF2JT30R0
• Physical space constraints: The RSF2JT30R0 has larger physical dimensions and may require board layout verification
• Procurement volume and lead time considerations
• Inventory availability: RSMF2JB30R0 has 855 units in stock; RSF2JT30R0 has 1149 units in stock

Both parts satisfy identical electrical and thermal performance requirements for circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT30R0 be used as a direct replacement for RSMF2JB30R0?

A: Yes. Both parts have identical resistance (30 Ohms), tolerance (±5%), power rating (2W), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 235°C). Electrical performance is equivalent.

Q: What is the difference between these two parts?

A: The primary differences are physical dimensions and packaging format. RSMF2JB30R0 measures 0.177" Dia x 0.433" L and is supplied in Bulk packaging. RSF2JT30R0 measures 0.217" Dia x 0.591" L and is supplied in Cut Tape format. Both are metal oxide film axial resistors with identical electrical specifications.

Q: Will the larger size of RSF2JT30R0 affect circuit performance?

A: No. Physical size does not affect electrical performance. However, board layout and mechanical clearance must accommodate the larger dimensions (5.50mm x 15.00mm versus 4.50mm x 11.00mm).

Q: Are both parts RoHS compliant?

A: Yes. Both RSMF2JB30R0 and RSF2JT30R0 are ROHS3 Compliant and REACH Unaffected.

Q: Which part should I select for new designs?

A: Selection depends on packaging requirements and inventory availability. Both parts are active production items with equivalent electrical performance. Verify physical dimensions against your PCB layout constraints.
