Key Parameters

Substitute Part Grouping Explanation

The RSMF1JB330R has one identified substitute part: RSMF1JT330R. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and share identical electrical and mechanical specifications. The substitution is valid based on the following key parameters:

• Resistance value: 330 Ohms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Physical dimensions: 0.126" Dia x 0.354" L (3.20mm x 9.00mm)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 200°C
• Number of terminations: 2
• RoHS and REACH compliance status

The only difference between these parts is the packaging format: RSMF1JB330R is supplied in Bulk packaging, while RSMF1JT330R is supplied in Cut Tape (CT) packaging.

Parameter Comparison

Engineering Selection Recommendations

Both RSMF1JB330R and RSMF1JT330R are active production parts with identical electrical performance and mechanical compatibility. Selection between these parts should be based on packaging requirements and inventory availability:

RSMF1JB330R (Bulk packaging) is suitable for applications requiring loose component handling or custom packaging workflows. RSMF1JT330R (Cut Tape packaging) is optimized for automated assembly processes and tape-and-reel handling systems.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications. The identical temperature coefficient and operating temperature range support direct substitution in thermal management and high-temperature circuit designs.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JT330R replace RSMF1JB330R in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Bulk). Substitution is valid for any application where the original part is specified.

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