ERG-3FJ682 Equivalent & Substitute Parts Reference

Part Overview

The ERG-3FJ682 is a 6.8 kOhms ±5% 3W axial through-hole resistor manufactured by Panasonic Electronic Components. This metal oxide film resistor features flame-proof and safety characteristics, with an operating temperature range of -55°C to 235°C. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (6.8 kOhms), tolerance (±5%), power rating (3W), composition (metal oxide film), and axial package configuration. All substitute parts listed maintain these core electrical and mechanical specifications. Operating temperature range, temperature coefficient, and feature set variations are documented to support design-specific selection criteria. All substitute parts are ROHS3 compliant and maintain the same HTSUS and ECCN classifications as the original part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical equivalence to the ERG-3FJ682 across resistance, tolerance, power rating, and composition specifications. Selection among substitutes should be based on the following criteria:

RSS3W6K8JTB (TE Connectivity) is a direct manufacturer equivalent with active product status and identical temperature coefficient. This part is suitable for applications requiring the original operating temperature range up to 155°C. High voltage and pulse withstanding features provide enhanced performance margins in demanding applications.

ROX3SJ6K8 (TE Connectivity) offers the widest operating temperature range among TE Connectivity options (-55°C to 200°C) with active product status. The slightly higher temperature coefficient (±350ppm/°C) remains within acceptable tolerance for most applications.

RSF3JB6K80 and RSF3JT6K80 (Stackpole Electronics) both provide the full operating temperature range matching the original part (-55°C to 235°C) with superior temperature coefficient stability (±200ppm/°C). These parts differ only in packaging format: RSF3JB6K80 is supplied in bulk, while RSF3JT6K80 is supplied in tape and reel format. Both maintain REACH Unaffected status.

Physical dimensions vary across substitutes. The original ERG-3FJ682 and RSS3W6K8JTB share identical length (0.591"), while ROX3SJ6K8 is slightly longer (0.630") and Stackpole parts are significantly larger (0.689" length, 6.00mm diameter). PCB layout and mechanical clearance must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can RSS3W6K8JTB replace ERG-3FJ682 in all applications? A: RSS3W6K8JTB is electrically equivalent across all core parameters. However, its maximum operating temperature is limited to 155°C compared to the original 235°C. Verify application temperature requirements before substitution.

Q: What is the difference between RSF3JB6K80 and RSF3JT6K80? A: Both parts are electrically and mechanically identical. RSF3JB6K80 is supplied in bulk packaging, while RSF3JT6K80 is supplied in tape and reel format. Selection depends on procurement and assembly process requirements.

Q: Are physical dimension differences critical for substitution? A: Physical dimensions vary across substitutes. Stackpole parts (RSF series) are larger than the original ERG-3FJ682. Verify PCB layout, component spacing, and mechanical clearances to ensure physical compatibility before substitution.

Q: Do all substitutes maintain the same compliance certifications? A: All substitute parts are ROHS3 compliant with identical HTSUS and ECCN classifications. REACH status varies: Panasonic and Stackpole parts are REACH Unaffected, while TE Connectivity parts show Vendor Undefined status. Verify compliance requirements for your specific application and region.

Q: Which substitute offers the best temperature stability? A: RSF3JB6K80 and RSF3JT6K80 (Stackpole) provide the lowest temperature coefficient at ±200ppm/°C, compared to ±300ppm/°C for the original part and RSS3W6K8JTB. This provides superior stability across temperature variations.
