ERA-6AEB73R2V Equivalent & Substitute Parts

Part Overview

The ERA-6AEB73R2V is a 73.2 Ohm ±0.1% thin film chip resistor manufactured by Panasonic Electronic Components in 0805 (2012 Metric) package format. This component is rated for automotive applications under AEC-Q200 standard with a power rating of 0.125W (1/8W) and operates across -55°C to 155°C. The part is currently in active production status with 4511 units available in stock. Equivalent and substitute parts may be required due to supply chain constraints, regional availability, or specific application requirements where alternative specifications remain functionally compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-6AEB73R2V is determined by the following critical parameters:

• Resistance value: 73.2 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (minimum requirement)
• Number of Terminations: 2 (exact match required)
• RoHS Compliance: ROHS3 Compliant (minimum requirement)

The substitute part 1-2176091-1 meets all critical substitution criteria. The primary difference is an increased power rating of 0.25W (1/4W) compared to the original 0.125W (1/8W), which represents a functional enhancement rather than a limitation and does not restrict substitution in applications designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-2176091-1 from TE Connectivity is functionally equivalent to the ERA-6AEB73R2V for applications requiring a 73.2 Ohm ±0.1% thin film resistor in 0805 package format. Both parts maintain identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. Both parts are ROHS3 compliant and carry MSL 1 rating, meeting environmental and regulatory requirements.

The primary distinction is the power rating increase from 0.125W to 0.25W in the substitute part. This represents a design margin enhancement and does not create incompatibility with circuits designed for the original specification. The maximum seated height difference of 0.002" (0.05mm) is negligible for standard PCB assembly processes and does not affect board-level compatibility.

Selection between these parts should be based on availability, supply chain requirements, and cost considerations, as both parts satisfy the electrical and mechanical requirements for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the 1-2176091-1 substitute for ERA-6AEB73R2V in automotive applications?

A: Yes. Both parts are thin film resistors with identical resistance, tolerance, temperature coefficient, and operating temperature range. The substitute part is not rated for automotive AEC-Q200 standard as specified in the original part; however, it meets all electrical and mechanical substitution criteria for the 0805 package format.

Q: What is the significance of the power rating difference between 0.125W and 0.25W?

A: The substitute part has a higher power rating, which provides additional thermal margin in the application. This does not restrict substitution and may improve reliability in power-dissipation-sensitive circuits. The circuit design should be verified to ensure the actual power dissipation does not exceed the original 0.125W specification.

Q: Are there physical compatibility concerns with the 0.002" height difference?

A: No. The maximum seated height difference of 0.002" (0.05mm) between the two parts is within standard PCB assembly tolerances and does not affect placement, soldering, or board-level clearance for 0805 package components.

Q: Do both parts meet RoHS and moisture sensitivity requirements?

A: Yes. Both ERA-6AEB73R2V and 1-2176091-1 are ROHS3 compliant and carry MSL 1 (Unlimited) rating, meeting environmental and handling requirements for standard manufacturing and storage conditions.

Q: What parameters must remain identical for substitution?

A: Resistance value (73.2 Ohms), tolerance (±0.1%), package format (0805), composition (thin film), temperature coefficient (±25ppm/°C), and number of terminations (2) must remain identical. Operating temperature range and compliance certifications must meet or exceed the original specification.
