RSF1JB47R0 Equivalent & Substitute Parts

Part Overview

The RSF1JB47R0 is a 47 Ohm, 1W through-hole axial resistor manufactured by Stackpole Electronics Inc. This metal oxide film resistor features flame retardant coating and is designed for general-purpose applications requiring reliable fixed resistance in axial package format. The part is currently active in production with ROHS3 compliance and maintains broad operating temperature range from -55°C to 235°C. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same resistance value, tolerance, power rating, and package type.

Substitute Part Grouping Explanation

The RSMF1JT47R0 qualifies as a direct substitute for the RSF1JB47R0 based on the following critical parameters:

• Identical resistance value: 47 Ohms
• Identical tolerance: ±5%
• Identical power rating: 1W
• Identical composition: Metal Oxide Film
• Identical package type: Axial
• Identical temperature coefficient: ±200ppm/°C
• Identical RoHS3 compliance status
• Both manufactured by Stackpole Electronics Inc

Substitution is valid when the application requirements do not exceed the specified electrical and thermal limits of either part. Physical dimension differences exist between the two parts and must be evaluated for mechanical fit within the target application.

Parameter Comparison

Engineering Selection Recommendations

Both RSF1JB47R0 and RSMF1JT47R0 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application-specific constraints:

The RSF1JB47R0 operates across a wider temperature range (-55°C to 235°C) and features flame retardant coating. The RSMF1JT47R0 operates to 200°C maximum and features flame proof construction, with a more compact physical footprint (3.20mm diameter vs 4.50mm diameter).

Applications requiring operation above 200°C must use the RSF1JB47R0. Applications with space constraints may benefit from the RSMF1JT47R0 compact dimensions. Both parts maintain identical electrical performance within their respective operating ranges.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JT47R0 replace RSF1JB47R0 in all applications?

A: Electrical substitution is valid when the application operates within the RSMF1JT47R0 maximum temperature of 200°C. Applications requiring operation above 200°C require the RSF1JB47R0. Physical space availability must also be confirmed due to dimensional differences.

Q: What are the physical dimension differences?

A: RSF1JB47R0 measures 0.177" diameter x 0.433" length (4.50mm x 11.00mm). RSMF1JT47R0 measures 0.126" diameter x 0.354" length (3.20mm x 9.00mm). The substitute part is smaller in both diameter and length.

Q: Are the coating specifications different?

A: RSF1JB47R0 features flame retardant coating. RSMF1JT47R0 features flame proof construction. Both are safety-rated metal oxide film resistors.

Q: Do both parts have identical electrical specifications?

A: Yes. Both parts are 47 Ohm ±5% 1W metal oxide film resistors with ±200ppm/°C temperature coefficient and identical RoHS3 compliance.

Q: What is the temperature operating range difference?

A: RSF1JB47R0 operates from -55°C to 235°C. RSMF1JT47R0 operates from -55°C to 200°C. The RSF1JB47R0 supports higher maximum temperature operation.
