Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB10R0 is determined by the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Metal Oxide Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 235°C (exact match required)
• Package type: Axial (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Identified substitutes maintain all critical electrical parameters. Variations exist in packaging format (bulk versus cut tape) and physical dimensions, which do not affect electrical performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and ROHS3 compliance. Selection between RSMF2JB10R0, RSMF2JT10R0, and RSF2JT10R0 is determined by packaging requirements and inventory availability rather than electrical performance.

RSMF2JB10R0 and RSMF2JT10R0 are electrically and mechanically identical, differing only in packaging format (bulk versus cut tape) and inventory levels. Both are from the RSMF series with identical physical dimensions.

RSF2JT10R0 represents an alternative from the RSF series with identical electrical specifications but larger physical dimensions (0.217" Dia x 0.591" L versus 0.177" Dia x 0.433" L). This part is suitable for applications where the larger form factor does not present space constraints.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT10R0 be used as a direct replacement for RSMF2JB10R0?

A: Yes. Both parts are electrically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. The difference is packaging format: RSMF2JB10R0 is supplied in bulk, while RSMF2JT10R0 is supplied in cut tape. Physical dimensions are identical.

Q: What is the difference between RSMF2JT10R0 and RSF2JT10R0?

A: Both parts have identical electrical specifications. The primary difference is physical size: RSMF2JT10R0 measures 0.177" Dia x 0.433" L, while RSF2JT10R0 measures 0.217" Dia x 0.591" L. RSF2JT10R0 also features flame retardant coating versus the flame-proof construction of RSMF2JT10R0. Both are suitable substitutes provided board layout accommodates the larger dimensions.

Q: Are all three parts ROHS3 compliant?

A: Yes. RSMF2JB10R0, RSMF2JT10R0, and RSF2JT10R0 are all ROHS3 compliant.

Q: Which part should I select if I need the smallest form factor?

A: RSMF2JB10R0 and RSMF2JT10R0 both offer the smallest dimensions at 0.177" Dia x 0.433" L. Selection between these two depends on packaging preference: bulk or cut tape.

Q: Can RSF2JT10R0 be used in space-constrained applications?

A: RSF2JT10R0 has larger physical dimensions than the RSMF series parts. Verify that board layout and component placement accommodate 0.217" Dia x 0.591" L before selection.
