ERJ-S1DF3162U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF3162U is a 31.6 kOhms ±1% thick film chip resistor rated for 0.75W power dissipation in a 2010 (5025 Metric) surface mount package. This component is manufactured by Panasonic Electronic Components and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status. Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF3162U is determined by strict equivalence across the following critical parameters:

• Resistance value: 31.6 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Height: 0.028" (0.70mm) maximum
• Termination count: 2
• RoHS compliance: ROHS3

The ERJ-12SF3162U meets all electrical and mechanical parameters required for direct substitution. Differences in product status and manufacturing series do not affect functional equivalence when all specified parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1DF3162U is the preferred selection for new designs due to its active production status. The ERJ-12SF3162U provides functional equivalence for all electrical and mechanical parameters and maintains full AEC-Q200 automotive qualification and ROHS3 compliance. Selection of the ERJ-12SF3162U is appropriate when supply availability of the primary part is constrained or when existing inventory of the substitute part is available for production use. Both parts are manufactured by Panasonic Electronic Components and are suitable for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3162U be used as a direct replacement for ERJ-S1DF3162U?

A: Yes. Both parts share identical electrical specifications (31.6 kOhms ±1%, 0.75W), identical package dimensions (2010 / 5025 Metric), identical temperature characteristics (±100ppm/°C, -55°C ~ 155°C operating range), and identical automotive qualification (AEC-Q200). Physical and functional compatibility is complete.

Q: What is the difference between these two part numbers?

A: The primary difference is product status. ERJ-S1DF3162U is in active production, while ERJ-12SF3162U is designated "Not For New Designs." Both parts are manufactured by Panasonic and meet identical specifications. The designation reflects manufacturing lifecycle positioning rather than performance or quality differences.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry AEC-Q200 automotive qualification, have Moisture Sensitivity Level 1 (Unlimited), and are REACH Unaffected. Compliance status is identical.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm), identical height (0.028" / 0.70mm maximum), and identical termination count (2) ensure mechanical and electrical interchangeability on PCB layouts designed for the 2010 package.

Q: Which part should be specified for new product designs?

A: ERJ-S1DF3162U should be specified for new designs due to active production status and long-term availability assurance. ERJ-12SF3162U may be used when supply constraints require alternative sourcing or when existing inventory is available for production.
