Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF6652U is determined by strict equivalence across the following parameters:

• Resistance value: 66.5 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-1TNF6652U meets all electrical and mechanical parameters required for direct substitution. This part belongs to the legacy ERJ-1TN series and carries a "Not For New Designs" status, making it suitable only for replacement or maintenance applications where the original specification must be maintained.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S1TF6652U is the preferred selection due to its active production status and anti-sulfur feature set. The ERJ-1TNF6652U substitute is electrically and mechanically equivalent and maintains full AEC-Q200 automotive compliance and ROHS3 certification. Selection of the substitute should be limited to replacement scenarios, legacy system maintenance, or situations where supply of the primary part is unavailable. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance characteristics within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF6652U be used as a direct replacement for ERJ-S1TF6652U in automotive applications?

A: Yes. Both parts meet identical electrical specifications (66.5 kOhms ±1%, 1W), operate across the same temperature range (-55°C ~ 155°C), and carry AEC-Q200 automotive qualification. The primary difference is product lifecycle status; ERJ-1TNF6652U is not recommended for new designs.

Q: What is the significance of the "Not For New Designs" status on ERJ-1TNF6652U?

A: This designation indicates the part is in mature or end-of-life phase. It remains available for purchase and performs to specification but should not be selected for new product development. Use the active ERJ-S1TF6652U for new designs.

Q: Are there package or footprint differences between these parts?

A: No. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERJ-S1TF6652U and ERJ-1TNF6652U are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is MSL 1 (unlimited) for both.

Q: What is the difference between anti-sulfur and standard thick film composition?

A: The ERJ-S1TF6652U includes anti-sulfur protection in its feature set, while ERJ-1TNF6652U does not explicitly list this feature. Both maintain ±100ppm/°C temperature coefficient and 1W power rating across the full operating range.
