ERJ-S1TF2703U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF2703U is a 270 kOhms ±1% 1W chip resistor manufactured by Panasonic Electronic Components in the 2512 (6432 Metric) package. 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 in active production status with 1120 units available in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package size, and automotive qualification standards. Alternative sources ensure supply chain flexibility and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2703U is determined by the following critical parameters:

• Resistance value: 270 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Automotive qualification: AEC-Q200 (required for equivalent application)
• Composition: Thick Film (required for performance characteristics)
• Temperature coefficient: ±100ppm/°C (required for stability)
• Operating temperature range: -55°C ~ 155°C (required for environmental compatibility)
• RoHS compliance: ROHS3 (required for regulatory alignment)

The CRCW2512270KFKEGHP from Vishay Dale meets all substitution criteria. While this part features a higher power rating (1.5W versus 1W), this represents an enhancement rather than a limitation, as the 2512 package dimensions remain identical and all electrical and environmental specifications align with or exceed the original part requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF2703U and CRCW2512270KFKEGHP are active production parts with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

• Supply availability and lead time requirements
• Inventory management and procurement strategy
• Thermal design margin requirements (the CRCW2512270KFKEGHP provides additional power dissipation capacity at 1.5W)
• Dimensional tolerance requirements (both parts maintain compatible 2512 package footprints with negligible dimensional variation)

Both parts are suitable for direct substitution in automotive and industrial applications requiring 270 kOhms ±1% thick film resistors with AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512270KFKEGHP replace the ERJ-S1TF2703U in existing designs?

A: Yes. Both parts share identical resistance, tolerance, package size, temperature coefficient, operating temperature range, and automotive qualification. The higher power rating of the substitute part (1.5W versus 1W) does not create compatibility issues and provides additional thermal margin.

Q: Are there dimensional differences between these parts?

A: Both parts use the 2512 (6432 Metric) package with identical maximum seated height of 0.028" (0.70mm). Length and width dimensions show minor variation (0.252" vs 0.248" L; 0.126" vs 0.124" W) within standard package tolerances and do not affect PCB layout or assembly compatibility.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S1TF2703U and CRCW2512270KFKEGHP carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting regulatory requirements for automotive and industrial applications.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there differences in temperature coefficient performance?

A: No. Both parts specify ±100ppm/°C temperature coefficient and operate across the identical -55°C ~ 155°C temperature range, ensuring equivalent stability and performance across environmental conditions.
