ERJ-S1TF1601U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF1601U is a 1.6 kOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently active in production with 1153 units in stock. Equivalent and substitute parts may be required due to supply chain constraints, design optimization for higher power ratings, or specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-S1TF1601U is determined by the following critical parameters:

• Resistance value: 1.6 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match or better required)
• Automotive Qualification: AEC-Q200 (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The power rating may be equal to or greater than 1W, as higher power ratings provide additional design margin without affecting electrical performance in the specified operating conditions. The CRCW25121K60FKEGHP from Vishay Dale meets all substitution criteria with an increased power rating of 1.5W.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF1601U and CRCW25121K60FKEGHP are active production parts with ROHS3 compliance and AEC-Q200 automotive qualification. The CRCW25121K60FKEGHP provides a higher power rating (1.5W versus 1W) while maintaining identical electrical characteristics, tolerance, temperature coefficient, and operating temperature range. Both parts are suitable for direct substitution in automotive and industrial applications requiring 1.6 kOhms ±1% thick film resistors in 2512 package format. Selection between these parts should be based on availability, supply chain requirements, and design margin considerations for power dissipation.

Frequently Asked Questions (FAQ)

Q: Can the CRCW25121K60FKEGHP replace the ERJ-S1TF1601U in my design?

A: Yes. Both parts share identical resistance (1.6 kOhms), tolerance (±1%), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The CRCW25121K60FKEGHP has a higher power rating (1.5W versus 1W), which provides additional design margin without affecting electrical performance.

Q: Are there any physical differences between these parts?

A: Dimensions are similar but not identical. The ERJ-S1TF1601U measures 0.252" L x 0.126" W (6.40mm x 3.20mm), while the CRCW25121K60FKEGHP measures 0.248" L x 0.124" W (6.30mm x 3.15mm). Both have identical maximum seated height of 0.028" (0.70mm). These minor dimensional variations are within typical PCB layout tolerances for 2512 package footprints.

Q: Do both parts meet automotive standards?

A: Yes. Both the ERJ-S1TF1601U and CRCW25121K60FKEGHP are AEC-Q200 qualified and suitable for automotive applications. Both are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What determines if a part can substitute for the ERJ-S1TF1601U?

A: Substitution requires exact matching of resistance value (1.6 kOhms), tolerance (±1%), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Power rating may be equal to or greater than the original specification.
