Substitute Part Grouping Explanation

Substitution eligibility for the PRSM2JT8R20 is determined by strict equivalence across the following critical parameters:

• Resistance value: 8.2 Ohms
• Tolerance: ±5%
• Power rating: 2W
• Composition: Metal Oxide Film
• Package configuration: Axial through-hole
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 235°C
• Physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
• Compliance certifications: ROHS3, REACH Unaffected

The identified substitute part RSMF2JT8R20 maintains complete electrical and mechanical equivalence. The primary distinction between the main part and substitute is the packaging format: PRSM2JT8R20 is supplied in Tape & Reel (TR) configuration, while RSMF2JT8R20 is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Stackpole Electronics Inc within the RSMF series and carry identical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both PRSM2JT8R20 and RSMF2JT8R20 are active production parts with identical electrical performance and mechanical compatibility. Selection between these parts should be based on packaging requirements and supply chain considerations:

PRSM2JT8R20 (Tape & Reel) is suitable for high-volume automated assembly operations where tape-and-reel packaging provides efficient component feeding through pick-and-place equipment.

RSMF2JT8R20 (Cut Tape) is appropriate for lower-volume applications, manual assembly processes, or situations where individual component access is required. This variant currently maintains significantly higher inventory availability.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements. The choice between packaging formats does not affect electrical performance, thermal characteristics, or reliability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RSMF2JT8R20 be used as a direct replacement for PRSM2JT8R20 in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid provided your assembly process can accommodate the Cut Tape format.

Q: Are there any performance differences between the two part numbers?

A: No. Both parts share identical resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. Performance in circuit applications is equivalent.

Q: What is the significance of the packaging format difference?

A: Tape & Reel (TR) packaging is optimized for automated high-speed assembly lines with pick-and-place equipment. Cut Tape (CT) packaging provides individual component access and is typically used for manual assembly, prototyping, or lower-volume production. The electrical and mechanical function remains unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PRSM2JT8R20 and RSMF2JT8R20 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. The identical electrical specifications (8.2 Ohms ±5%, 2W, ±200ppm/°C, -55°C to 235°C operating range) and axial through-hole package ensure functional interchangeability in any circuit application designed for either part number.
