Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2AEB73R2X is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 73.2 Ohms
• Tolerance: ±0.1%
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Allowable Variation Parameters:

• Temperature coefficient: ±25ppm/°C or better (lower values acceptable)
• Physical height: Maximum seated height up to 0.016" (0.40mm)
• Supplier device package designation: 0402

All identified substitute parts meet these criteria and are classified as direct equivalents or performance upgrades based on temperature coefficient specifications.

Parameter Comparison

Engineering Selection Recommendations

ERA-2AEB73R2X (Panasonic Electronic Components): Primary selection for automotive applications requiring AEC-Q200 qualification. Highest inventory availability (6895 units) supports production volume requirements. Temperature coefficient of ±25ppm/°C meets standard precision applications.

CPF0402B73R2E1 (TE Connectivity Passive Product): Direct functional equivalent with identical electrical specifications. Slightly reduced physical height (0.014" vs 0.016") provides design flexibility for space-constrained layouts. Suitable for non-automotive applications or where automotive qualification is not required. Secondary inventory availability (1006 units).

RN73C1E73R2BTDF (TE Connectivity Passive Product): Performance upgrade option with superior temperature coefficient of ±10ppm/°C (versus ±25ppm/°C). Recommended for precision measurement circuits, high-stability applications, or designs requiring tighter tolerance performance. Limited inventory (855 units). Identical physical dimensions and electrical ratings otherwise.

All three parts are ROHS3 compliant, MSL 1 rated, and support unlimited moisture exposure without baking requirements.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B73R2E1 replace ERA-2AEB73R2X in automotive applications? A: CPF0402B73R2E1 is electrically and mechanically equivalent but does not carry AEC-Q200 automotive qualification. Use only in non-automotive designs or where automotive qualification is not a design requirement.

Q: What is the advantage of RN73C1E73R2BTDF over the other options? A: RN73C1E73R2BTDF features a ±10ppm/°C temperature coefficient compared to ±25ppm/°C for the other parts. This superior stability is beneficial for precision analog circuits, reference networks, and applications requiring minimal temperature-induced resistance drift.

Q: Are all three parts physically interchangeable? A: Yes. All three parts use 0402 (1005 Metric) package with 2 terminations. CPF0402B73R2E1 and RN73C1E73R2BTDF have slightly lower maximum seated height (0.014" vs 0.016"), which is advantageous for compact designs but does not prevent interchangeability.

Q: Do any of these parts require baking before use? A: No. All three parts are rated MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require moisture bake-out procedures prior to soldering.

Q: Which part should I select for new designs? A: For automotive applications, specify ERA-2AEB73R2X (AEC-Q200 qualified). For precision non-automotive applications, RN73C1E73R2BTDF offers superior temperature stability. For general-purpose applications, CPF0402B73R2E1 provides cost-effective equivalence.

Q: Are there any compliance differences between these parts? A: All three parts are ROHS3 compliant with EAR99 ECCN classification and HTSUS code 8533.21.0030. ERA-2AEB73R2X carries explicit AEC-Q200 automotive qualification; the TE Connectivity parts do not list this certification.
