RN73C1J4K7ATDF Equivalent & Substitute Parts

Part Overview

The RN73C1J4K7ATDF is a 4.7 kOhms ±0.05% thin film chip resistor manufactured by TE Connectivity Passive Product in the 0603 (1608 Metric) package format. This component is rated for 0.063W (1/16W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers while meeting or exceeding the original specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN73C1J4K7ATDF is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 4.7 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)

Mechanical Parameters:

• Package format: 0603 (1608 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thin Film (exact match required)

Regulatory & Compliance Parameters:

• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (required)

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.063W or greater) are acceptable, as increased power dissipation capability does not compromise circuit performance in applications designed for the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and mechanical requirements for direct replacement of the RN73C1J4K7ATDF.

ERA-3ARW472V (Panasonic Electronic Components): This substitute is rated for automotive applications under AEC-Q200 qualification. The part maintains all critical electrical parameters while providing increased power dissipation capability (0.1W versus 0.063W). ROHS3 compliance and REACH Unaffected status are confirmed. This part is suitable for applications requiring automotive-grade reliability.

RG1608N-472-W-T5 (Susumu): This substitute incorporates anti-sulfur technology in addition to AEC-Q200 automotive qualification. The part maintains all critical electrical parameters with increased power dissipation capability (0.1W versus 0.063W). ROHS3 compliance and REACH Unaffected status are confirmed. The seated height is marginally reduced (0.020" versus 0.022"), which may provide advantages in space-constrained applications. This part is suitable for automotive and harsh environment applications.

Both substitutes are active products with confirmed inventory availability and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can ERA-3ARW472V or RG1608N-472-W-T5 be used as direct replacements for RN73C1J4K7ATDF?

A: Yes. Both substitute parts maintain identical resistance values (4.7 kOhms), tolerance (±0.05%), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), package format (0603), and composition (thin film). All three parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference in power rating between the main part and substitutes?

A: The RN73C1J4K7ATDF is rated for 0.063W (1/16W), while both ERA-3ARW472V and RG1608N-472-W-T5 are rated for 0.1W (1/10W). The higher power rating of the substitutes does not affect circuit performance in applications designed for the original specification, as increased power dissipation capability is a non-limiting parameter.

Q: Are there mechanical compatibility concerns with the substitute parts?

A: No. All three parts use the 0603 (1608 Metric) package format with identical termination count (2) and composition (thin film). The RG1608N-472-W-T5 has a slightly reduced seated height (0.020" versus 0.022"), which is within acceptable tolerance for standard PCB assembly processes.

Q: What certifications do the substitute parts carry?

A: ERA-3ARW472V carries AEC-Q200 automotive qualification and REACH Unaffected status. RG1608N-472-W-T5 carries AEC-Q200 automotive qualification with anti-sulfur technology and REACH Unaffected status. Both are ROHS3 compliant.

Q: Can these parts be used interchangeably in the same circuit?

A: Yes. The electrical parameters (resistance, tolerance, temperature coefficient, operating temperature range) are identical across all three parts. The package format and mechanical dimensions are compatible. Selection between parts may be based on manufacturer preference, availability, or specific application requirements such as automotive qualification or anti-sulfur protection.

Q: What is the significance of the anti-sulfur feature in RG1608N-472-W-T5?

A: Anti-sulfur technology provides enhanced protection against sulfur-containing environmental contaminants. This feature is beneficial in applications exposed to harsh industrial or marine environments where sulfur compounds may be present.
