Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603DRE0730K9L is determined by the following critical parameters:

• Resistance Value: Must be 30.9 kOhms (exact match required)
• Package / Case: Must be 0603 (1608 Metric) for PCB footprint compatibility
• Power Rating: Minimum 0.1W; higher ratings are acceptable
• Tolerance: ±0.5% or better (lower tolerance values are acceptable upgrades)
• Composition: Thin film technology
• Operating Temperature Range: Must encompass -55°C ~ 155°C
• RoHS Compliance: ROHS3 Compliant

Substitute parts meeting these criteria are functionally interchangeable. Enhanced specifications such as improved tolerance (±0.1%), lower temperature coefficient (±25ppm/°C), or automotive qualification (AEC-Q200) represent performance upgrades without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the RT0603DRE0730K9L within the specified operating parameters.

RT0603BRD0730K9L (YAGEO): Direct upgrade from the main part with improved tolerance (±0.1% vs ±0.5%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C). Maintains identical power rating and package specifications. ROHS3 compliant with unlimited moisture sensitivity rating.

4-2176089-3 (TE Connectivity): Functionally equivalent with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Offers higher power rating (0.167W vs 0.1W). Dimensions vary slightly (1.55mm L vs 1.60mm L). ROHS3 compliant. REACH status vendor undefined.

ERA-3AEB3092V (Panasonic): Upgrade option with ±0.1% tolerance, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. Identical power rating and package to main part. ROHS3 compliant with REACH unaffected status.

RG1608P-3092-B-T5 (Susumu): Premium option combining ±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification, and anti-sulfur features. Seated height 0.020" (0.50mm) versus 0.022" (0.55mm) for main part. ROHS3 compliant with REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0730K9L replace RT0603DRE0730K9L in all applications?

A: Yes. RT0603BRD0730K9L is a direct upgrade with superior tolerance and temperature coefficient specifications while maintaining identical package, power rating, and operating temperature range.

Q: What is the difference between 0.1W and 0.167W power ratings?

A: Both ratings are acceptable substitutes. The 0.167W rating in 4-2176089-3 provides additional thermal margin. Power dissipation requirements of the circuit determine whether this upgrade is necessary.

Q: Are automotive-qualified parts (ERA-3AEB3092V, RG1608P-3092-B-T5) suitable for non-automotive applications?

A: Yes. Automotive-qualified components meet or exceed standard industrial specifications and are fully compatible with non-automotive designs.

Q: Does the anti-sulfur feature of RG1608P-3092-B-T5 provide additional benefit?

A: Anti-sulfur coating provides enhanced reliability in high-sulfur environments. For standard applications, this feature is not required but does not negatively impact performance.

Q: Are there physical footprint differences between substitute parts?

A: All parts use 0603 (1608 Metric) package with compatible PCB footprints. Minor dimensional variations (length 1.55mm to 1.60mm, height 0.50mm to 0.55mm) do not affect standard PCB layout compatibility.

Q: Which substitute offers the best overall performance?

A: RG1608P-3092-B-T5 provides the most comprehensive specification set with ±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 qualification, and anti-sulfur protection. Selection depends on application-specific requirements and cost considerations.
