Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF1JT910R is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 910 Ohms
• Tolerance: ±5%
• Composition: Metal Oxide Film
• Package type: Axial
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 235°C
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating: May be equal to or greater than the original 1W specification, provided the physical dimensions remain compatible with the axial package form factor and circuit board layout constraints.

The RSMF2JT910R qualifies as a substitute part because it maintains all mandatory matching parameters while offering an upgraded 2W power rating within the same axial package dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the RSF1JT910R and RSMF2JT910R are active products from Stackpole Electronics Inc with full ROHS3 compliance and REACH unaffected status. The RSMF2JT910R provides increased power dissipation capability at 2W while maintaining identical electrical characteristics and physical form factor. Selection between these parts depends on circuit power requirements: the RSF1JT910R is suitable for applications with 1W or lower dissipation budgets, while the RSMF2JT910R accommodates designs requiring up to 2W continuous power handling. Both parts are suitable for industrial and commercial applications within the specified operating temperature range of -55°C to 235°C.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT910R replace RSF1JT910R in all applications?

A: The RSMF2JT910R is electrically and mechanically compatible with RSF1JT910R applications. The higher 2W power rating does not create incompatibility; it provides additional thermal margin. Verify that circuit board layout accommodates the identical axial package dimensions (0.177" Dia x 0.433" L).

Q: What is the primary difference between these two parts?

A: The primary difference is power rating: RSF1JT910R is rated at 1W while RSMF2JT910R is rated at 2W. All other electrical parameters, including resistance value, tolerance, temperature coefficient, and operating temperature range, are identical.

Q: Are both parts RoHS compliant?

A: Yes, both RSF1JT910R and RSMF2JT910R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Do these parts have identical physical dimensions?

A: Yes, both parts share identical axial package dimensions of 0.177" Dia x 0.433" L (4.50mm x 11.00mm), ensuring direct mechanical compatibility in circuit board layouts.

Q: What temperature range do these resistors support?

A: Both parts operate across the temperature range of -55°C to 235°C with a temperature coefficient of ±200ppm/°C, suitable for industrial and high-temperature applications.
