Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RSF1JTR430 is determined by the following critical parameters:

• Resistance value: 430 mOhms
• Tolerance: ±5%
• Power rating: 1W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Temperature coefficient: ±200ppm/°C
• RoHS compliance: ROHS3 Compliant
• Termination count: 2

The RSMF1JTR430 meets all electrical specifications and maintains mechanical compatibility as an axial package. Packaging format differs (Cut Tape versus Tape & Reel), which does not affect electrical or mechanical substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Both RSF1JTR430 and RSMF1JTR430 are active products from Stackpole Electronics Inc with ROHS3 compliance. The primary differences are physical dimensions and maximum operating temperature. The RSF1JTR430 supports operation to 235°C, while the RSMF1JTR430 is rated to 200°C. Selection between these parts depends on thermal environment requirements and available board space. Both parts maintain identical electrical performance across the specified tolerance and temperature coefficient parameters.

Frequently Asked Questions (FAQ)

Q: Can RSMF1JTR430 replace RSF1JTR430 in all applications?

A: Electrical substitution is valid when operating temperatures do not exceed 200°C. The RSF1JTR430 supports higher temperature operation to 235°C. Physical dimensions differ; verify PCB layout compatibility before substitution.

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

A: Tape & Reel (TR) packaging is supplied on continuous tape for automated assembly equipment. Cut Tape (CT) packaging is supplied as individual tape segments. Both formats contain identical components; packaging selection depends on assembly process requirements.

Q: Are the resistance and tolerance values identical between these parts?

A: Yes. Both RSF1JTR430 and RSMF1JTR430 are specified at 430 mOhms with ±5% tolerance and identical temperature coefficient of ±200ppm/°C.

Q: What are the physical size constraints for substitution?

A: RSF1JTR430 measures 0.177" diameter by 0.433" length. RSMF1JTR430 measures 0.126" diameter by 0.354" length. The substitute part is physically smaller and may require PCB layout verification for lead spacing and component clearance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0090.
