PRSM2JTR680 Equivalent & Substitute Parts
Part Overview
The PRSM2JTR680 is a 680 mOhms ±5% 2W through-hole resistor manufactured by Stackpole Electronics Inc. This axial metal oxide film resistor features flame-proof and safety characteristics, designed for applications requiring precision current-limiting and load-balancing functions. The part is currently active in production with ROHS3 compliance and REACH unaffected status. Substitute parts are identified when packaging format changes or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
The RSMF2JTR680 qualifies as a parametric equivalent to the PRSM2JTR680 based on the following criteria:
- Identical resistance value: 680 mOhms
- Identical tolerance: ±5%
- Identical power rating: 2W
- Identical composition: Metal Oxide Film
- Identical package type: Axial
- Identical physical dimensions: 0.177" Dia x 0.433" L (4.50mm x 11.00mm)
- Identical temperature coefficient: ±200ppm/°C
- Identical operating temperature range: -55°C ~ 235°C
- Identical features: Flame Proof, Safety
- Identical number of terminations: 2
- Identical RoHS and REACH compliance status
The only difference between these parts is the packaging format: PRSM2JTR680 is supplied in Tape & Reel (TR) format, while RSMF2JTR680 is supplied in Cut Tape (CT) format. Both formats contain identical components with no electrical or mechanical performance variation.

Engineering Selection Recommendations
Both PRSM2JTR680 and RSMF2JTR680 are active production parts from Stackpole Electronics Inc with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability:
- PRSM2JTR680 in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous component feed.
- RSMF2JTR680 in Cut Tape format is suitable for lower-volume applications, manual assembly, or situations where smaller quantity packaging is preferred.
Both parts maintain full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all applications. The identical thermal characteristics (±200ppm/°C, -55°C ~ 235°C operating range) and flame-proof safety features make either part suitable for the same circuit applications without performance degradation.
Frequently Asked Questions (FAQ)
Q: Can RSMF2JTR680 be used as a direct replacement for PRSM2JTR680 in production?
A: Yes. The RSMF2JTR680 is electrically and mechanically identical to the PRSM2JTR680. The only difference is packaging format (Cut Tape vs. Tape & Reel). Direct substitution is valid for any application where the component specifications are the determining factor.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly or lower-volume production runs. The components themselves are identical.
Q: Are there any thermal performance differences between these parts?
A: No. Both parts have identical temperature coefficients (±200ppm/°C) and operating temperature ranges (-55°C ~ 235°C). Thermal performance is equivalent.
Q: Do both parts meet the same compliance standards?
A: Yes. Both PRSM2JTR680 and RSMF2JTR680 are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.
Q: Can these parts be mixed in the same assembly?
A: Yes. Since the electrical and mechanical specifications are identical, mixing packaging formats in the same assembly presents no technical issues. Assembly process considerations may apply based on production equipment capabilities.
