Key Parameters

Substitute Part Grouping Explanation

The RSMF2JT27R0 qualifies as a direct substitute for the RSF2JB27R0 based on the following critical parameters:

• Identical resistance value: 27 Ohms
• Identical tolerance: ±5%
• Identical power rating: 2W
• Identical composition: Metal Oxide Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 235°C
• Identical package type: Axial
• Identical RoHS compliance: ROHS3 Compliant
• Identical electrical terminations: 2

The primary difference is packaging format: RSF2JB27R0 is supplied in Bulk packaging, while RSMF2JT27R0 is supplied in Cut Tape (CT) format. Both parts are manufactured by Stackpole Electronics Inc and maintain identical electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both RSF2JB27R0 and RSMF2JT27R0 are active production parts with ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and inventory availability. The RSMF2JT27R0 offers higher inventory availability (3115 units) in Cut Tape format, suitable for automated assembly processes. The RSF2JB27R0 in Bulk packaging may be preferred for manual assembly or applications where tape packaging is not required. Both parts maintain identical electrical performance and thermal characteristics across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT27R0 be used as a direct replacement for RSF2JB27R0?

A: Yes. Both parts have identical electrical specifications: 27 Ohms resistance, ±5% tolerance, 2W power rating, metal oxide film composition, and operating temperature range of -55°C to 235°C. The difference is packaging format only.

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

A: Bulk packaging supplies loose components suitable for manual assembly or small-scale applications. Cut Tape (CT) packaging supplies components on continuous tape, designed for automated pick-and-place assembly equipment. Electrical performance is identical.

Q: Are there any thermal or electrical performance differences between these parts?

A: No. Both parts have identical temperature coefficients (±200ppm/°C), operating temperature ranges (-55°C ~ 235°C), and power dissipation ratings (2W).

Q: Do both parts meet the same compliance standards?

A: Yes. Both RSF2JB27R0 and RSMF2JT27R0 are ROHS3 compliant and REACH unaffected.

Q: Which part should I select for high-volume production?

A: RSMF2JT27R0 in Cut Tape format is optimized for automated assembly processes typical in high-volume production. The higher available inventory (3115 units) also supports production continuity.
