Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14J133U is determined by strict equivalence across the following critical parameters:

• Resistance value: 13 kOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14YJ133U from Panasonic meets all electrical and mechanical parameter requirements for direct substitution. This part belongs to the ERJ-14 series and maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both parts are thick film compositions with AEC-Q200 automotive qualification and full RoHS3 compliance.

Engineering Selection Recommendations

The ERJ-S14J133U is the recommended primary selection for new designs due to its active production status. The ERJ-14YJ133U is electrically and mechanically equivalent and maintains full AEC-Q200 automotive qualification and ROHS3 compliance. However, the ERJ-14YJ133U carries a "Not For New Designs" status, indicating that Panasonic has transitioned this series to legacy support. Selection of the ERJ-14YJ133U should be limited to applications requiring component replacement in existing designs or where supply constraints on the primary part necessitate substitution. Both parts are functionally interchangeable within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14YJ133U replace ERJ-S14J133U in new designs?

A: ERJ-14YJ133U meets all electrical and mechanical specifications for functional equivalence. However, it carries "Not For New Designs" status. New designs should specify ERJ-S14J133U to ensure long-term supply continuity and manufacturer support.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S14J133U and ERJ-14YJ133U are AEC-Q200 qualified and suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: What is the difference between ERJ-S14 and ERJ-14 series?

A: Both series are Panasonic thick film chip resistors with identical electrical characteristics and package formats. The ERJ-S14 series represents the current production line, while ERJ-14 is a legacy series maintained for existing design support only.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
