ERJ-S1TF5900U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF5900U is a 590 Ohms ±1% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This part is rated for automotive applications under AEC-Q200 and features anti-sulfur protection. The part is currently active in production. Substitute parts may be required due to inventory constraints, supply chain discontinuation of specific series, or design flexibility across qualified manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (590 Ohms), tolerance (±1%), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. All substitute parts listed meet these core electrical and mechanical requirements and are qualified for direct replacement in automotive applications.

The identified substitute parts are grouped by manufacturer and product status. ERJ-1TNF5900U (Panasonic) maintains identical specifications but carries a "Not For New Designs" status. AC2512FK-07590RL (YAGEO), CRCW2512590RFKEGHP (Vishay Dale), and RMCF2512FT590R (Stackpole Electronics) are all active products with equivalent or superior ratings. CRCW2512590RFKEGHP offers enhanced pulse withstanding capability at 1.5W, providing additional design margin while maintaining full compatibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs, select from the active product status alternatives: AC2512FK-07590RL (YAGEO), CRCW2512590RFKEGHP (Vishay Dale), or RMCF2512FT590R (Stackpole Electronics). All three maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

CRCW2512590RFKEGHP is suitable when additional thermal margin is required, as its 1.5W rating provides 50% power headroom over the 1W specification while maintaining identical electrical characteristics and package footprint.

ERJ-1TNF5900U (Panasonic) is electrically and mechanically equivalent but carries "Not For New Designs" status; use only for legacy design maintenance or existing production continuity where supply of the primary part is unavailable.

All substitute parts are qualified for direct PCB footprint replacement without layout modification, as the 2512 package dimensions are standardized across manufacturers within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512590RFKEGHP replace ERJ-S1TF5900U in existing designs? A: Yes. CRCW2512590RFKEGHP meets all electrical specifications (590 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and is AEC-Q200 rated. The 1.5W rating is a superset of the 1W requirement and does not affect circuit operation. The 2512 package footprint is identical.

Q: Why is ERJ-1TNF5900U marked "Not For New Designs"? A: ERJ-1TNF5900U is electrically and mechanically equivalent to ERJ-S1TF5900U but is designated for legacy support only. New designs should use active product alternatives to ensure long-term supply availability.

Q: Are there dimensional differences between substitute parts? A: Minor dimensional variations exist within the 2512 package standard. ERJ-S1TF5900U and RMCF2512FT590R are 0.252" L × 0.126" W. AC2512FK-07590RL is 0.250" L × 0.122" W. CRCW2512590RFKEGHP is 0.248" L × 0.124" W. All variations are within standard PCB footprint tolerances and do not require layout changes.

Q: Do all substitute parts have the same moisture sensitivity rating? A: Yes. All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute offers the best long-term supply availability? A: RMCF2512FT590R (Stackpole Electronics) and AC2512FK-07590RL (YAGEO) are both active products from established manufacturers with broad distribution networks. CRCW2512590RFKEGHP (Vishay Dale) is also active and widely available.
