ERA-3AEB8451V Equivalent & Substitute Parts

Part Overview

The ERA-3AEB8451V is an 8.45 kOhms ±0.1% thin film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Panasonic Electronic Components, this component meets automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is active in production with 1787 units currently in stock. Substitute parts are identified when electrical specifications, mechanical dimensions, and compliance ratings align within acceptable tolerances for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters:

• Resistance value: 8.45 kOhms
• Tolerance: ±0.1%
• Package type: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• RoHS3 compliance
• MSL rating: 1

The three identified substitute parts meet these core criteria. Variations in power rating (0.1W vs. 0.21W), operating temperature upper limit (155°C vs. 175°C), and additional features (anti-sulfur, moisture resistant) represent enhancements or extended capabilities that do not prevent substitution when the primary electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All four parts are active products with ROHS3 compliance and MSL rating 1. Selection between ERA-3AEB8451V and its substitutes depends on application-specific requirements:

RG1608P-8451-B-T5 (Susumu) provides anti-sulfur and automotive AEC-Q200 qualification with slightly reduced seated height (0.020" vs. 0.022"), suitable for space-constrained automotive applications.

RT0603BRD078K45L (YAGEO) matches all core electrical and mechanical specifications but lacks explicit AEC-Q200 automotive rating. This part is appropriate for non-automotive or general industrial applications where automotive qualification is not required.

TNPW06038K45BEEA (Vishay Dale) offers enhanced power rating (0.21W vs. 0.1W), extended operating temperature range to 175°C, anti-sulfur coating, and moisture-resistant construction. This part is suitable for applications requiring higher thermal margin or extended temperature operation while maintaining AEC-Q200 compliance.

Frequently Asked Questions (FAQ)

Q: Can I substitute ERA-3AEB8451V with any of these parts on an automotive circuit board?

A: RG1608P-8451-B-T5 and TNPW06038K45BEEA both carry AEC-Q200 automotive qualification and are suitable for automotive applications. RT0603BRD078K45L lacks explicit automotive rating and should be used only in non-automotive designs unless automotive qualification is not a design requirement.

Q: What is the difference in power rating between ERA-3AEB8451V and TNPW06038K45BEEA?

A: ERA-3AEB8451V is rated for 0.1W dissipation, while TNPW06038K45BEEA is rated for 0.21W. The higher power rating of TNPW06038K45BEEA provides additional thermal margin in applications with higher current flow but does not affect substitution compatibility when power dissipation remains within the 0.1W specification.

Q: Are all substitute parts available in the same package dimensions?

A: All parts use 0603 (1608 Metric) package. Seated height varies slightly: RG1608P-8451-B-T5 measures 0.020" maximum, while ERA-3AEB8451V, RT0603BRD078K45L, and TNPW06038K45BEEA measure 0.022" maximum. These variations are within standard PCB assembly tolerances and do not prevent direct substitution.

Q: Which substitute part offers the widest operating temperature range?

A: TNPW06038K45BEEA operates from -55°C to 175°C, extending 20°C above the ERA-3AEB8451V specification of -55°C to 155°C. This extended range is beneficial for applications in high-temperature environments.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All four parts—ERA-3AEB8451V, RG1608P-8451-B-T5, RT0603BRD078K45L, and TNPW06038K45BEEA—are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level).
