Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSMF2JB47R0 is determined by strict alignment of the following parameters:

• Resistance value: 47 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial with 2 terminations
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 classification

The RSF2JT47R0 meets all electrical and mechanical substitution criteria. Both parts share identical resistance, tolerance, power rating, composition, and thermal specifications. Physical dimensions differ due to packaging format variation (Bulk versus Cut Tape), but both maintain axial configuration compatibility with standard through-hole PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The RSF2JT47R0 is a qualified substitute for the RSMF2JB47R0 based on electrical equivalence and compliance alignment. Both parts are manufactured by Stackpole Electronics Inc, maintain active product status, and carry identical ROHS3, REACH, and export classification certifications. The primary distinction is packaging format and physical dimensions. The RSF2JT47R0 is supplied in Cut Tape format with larger axial dimensions (0.217" diameter × 0.591" length) compared to the Bulk-packaged RSMF2JB47R0 (0.177" diameter × 0.433" length). Selection between these parts depends on PCB layout constraints and assembly process requirements rather than electrical performance.

Frequently Asked Questions (FAQ)

Q: Can RSF2JT47R0 replace RSMF2JB47R0 in existing circuit designs?

A: Yes. Both parts deliver identical electrical performance with 47 Ohms resistance, ±5% tolerance, 2W power rating, and ±200ppm/°C temperature coefficient across the -55°C to 235°C operating range. Substitution is electrically valid.

Q: What are the physical dimension differences between these parts?

A: The RSMF2JB47R0 measures 0.177" diameter × 0.433" length (4.50mm × 11.00mm). The RSF2JT47R0 measures 0.217" diameter × 0.591" length (5.50mm × 15.00mm). Both maintain axial configuration with 2 terminations. PCB layout spacing must accommodate the larger RSF2JT47R0 dimensions.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both RSMF2JB47R0 and RSF2JT47R0 are ROHS3 Compliant and REACH Unaffected, with EAR99 export classification and 8533.21.0090 HTSUS code.

Q: What is the difference between Bulk and Cut Tape packaging?

A: Bulk packaging (RSMF2JB47R0) supplies loose components suitable for manual assembly or bulk handling. Cut Tape packaging (RSF2JT47R0) provides components on continuous tape for automated pick-and-place assembly systems. Electrical specifications remain identical.

Q: Which part should be selected for new designs?

A: Selection depends on assembly methodology. Use RSF2JT47R0 for automated assembly lines requiring tape-and-reel format. Use RSMF2JB47R0 for manual assembly or applications where bulk packaging is preferred. Both deliver equivalent electrical performance.
