RT0603FRE0736K5L Equivalent & Substitute Parts

Part Overview

The RT0603FRE0736K5L is a 36.5 kOhms ±1% thin film chip resistor in 0603 (1608 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Finding equivalent and substitute parts becomes necessary when managing inventory constraints, lead time requirements, or when design specifications allow for improved tolerance or performance characteristics within the same package and electrical envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603FRE0736K5L is determined by strict adherence to the following parameters:

Primary Substitution Criteria (Must Match):

• Resistance value: 36.5 kOhms
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 or equivalent
• Moisture sensitivity: MSL 1 or better

Secondary Substitution Criteria (Allowable Variations):

• Tolerance: ±1% or tighter (±0.5%, ±0.1%)
• Power rating: 0.1W or higher (0.167W acceptable)
• Temperature coefficient: ±50ppm/°C or tighter (±25ppm/°C acceptable)
• Manufacturer: Any qualified supplier meeting above criteria

Substitute parts are grouped into three categories: Upgrade (improved tolerance/performance), Direct (equivalent from different manufacturer), and Compatible (same electrical function with minor dimensional variance).

Parameter Comparison

Engineering Selection Recommendations

YAGEO RT Series (Same Manufacturer): RT0603BRD0736K5L, RT0603DRD0736K5L, and RT0603DRE0736K5L are direct upgrades within the YAGEO product line, offering improved tolerance specifications (±0.1% or ±0.5%) while maintaining identical package geometry and power rating. All remain ROHS3 compliant with MSL 1 rating. Selection among these variants depends on tolerance requirements: RT0603BRD0736K5L provides the tightest tolerance (±0.1%) with improved temperature coefficient (±25ppm/°C), while RT0603DRE0736K5L offers ±0.5% tolerance with higher inventory availability (11194 units).

Cross-Manufacturer Alternatives: ERA-3AEB3652V (Panasonic) and RG1608P-3652-B-T5 (Susumu) both provide ±0.1% tolerance with automotive AEC-Q200 qualification. ERA-3AEB3652V offers the highest inventory level (16717 units) and maintains standard 0.1W power rating. RG1608P-3652-B-T5 includes anti-sulfur coating and AEC-Q200 rating, suitable for automotive applications, though inventory is limited (1003 units).

Higher Power Alternative: 5-2176089-0 (TE Connectivity) provides ±0.1% tolerance with elevated power rating (0.167W, 1/6W) in the same 0603 package. This part is suitable when additional thermal margin is required, though physical dimensions show minor variance (1.55mm length vs. 1.60mm standard).

All listed substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C ~ 155°C operating temperature range, ensuring direct compatibility with the original RT0603FRE0736K5L specification envelope.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0736K5L replace RT0603FRE0736K5L in any application? A: Yes. RT0603BRD0736K5L is a direct substitute with improved tolerance (±0.1% vs. ±1%) and tighter temperature coefficient (±25ppm/°C vs. ±50ppm/°C). The identical 0603 package, 0.1W power rating, and ROHS3/MSL 1 compliance ensure pin-for-pin compatibility. Applications requiring tighter tolerance specifications benefit from this upgrade.

Q: What is the difference between RT0603DRD0736K5L and RT0603DRE0736K5L? A: Both parts share ±0.5% tolerance and ±25ppm/°C temperature coefficient. The primary difference is temperature coefficient specification: RT0603DRE0736K5L maintains ±50ppm/°C (matching the original part's temperature stability), while RT0603DRD0736K5L offers ±25ppm/°C for improved thermal performance. RT0603DRE0736K5L has significantly higher inventory (11194 vs. 1666 units).

Q: Are Panasonic ERA-3AEB3652V and Susumu RG1608P-3652-B-T5 suitable for non-automotive applications? A: Yes. Both parts exceed standard industrial requirements with AEC-Q200 automotive qualification. The ±0.1% tolerance, ±25ppm/°C temperature coefficient, and ROHS3 compliance make them suitable for precision analog circuits, measurement equipment, and general industrial applications. Automotive qualification indicates higher reliability standards applicable across all use cases.

Q: Does the 0.167W power rating of 5-2176089-0 affect circuit compatibility? A: No. The higher power rating (0.167W vs. 0.1W) provides additional thermal margin without affecting electrical performance. The part is suitable for applications where the original 0.1W rating is marginal or where thermal stress reduction is beneficial. Physical dimensions show minor variance (1.55mm vs. 1.60mm length), which is negligible for standard PCB layouts.

Q: Which substitute offers the best inventory availability? A: ERA-3AEB3652V (Panasonic) provides the highest inventory level at 16717 units, combined with ±0.1% tolerance and ROHS3 compliance. For YAGEO-specific sourcing, RT0603DRE0736K5L offers 11194 units with ±0.5% tolerance.

Q: Are all substitutes MSL 1 rated? A: Yes. All listed substitutes maintain MSL 1 (Unlimited) moisture sensitivity rating, identical to the original RT0603FRE0736K5L. No special moisture control or baking procedures are required for any substitute part.
