Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603FRE07309KL is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 309 kOhms (exact match required)
• Package form factor: 0603 (1608 Metric) SMD
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance status

Tolerance Consideration: The main part specifies ±1% tolerance. Substitute parts with tighter tolerances (±0.5%, ±0.1%) are electrically compatible and represent upgrades in precision. Parts with looser tolerances are not suitable substitutes.

Power Rating Consideration: The main part is rated at 0.1W (1/10W). Substitute parts rated at 0.1W or higher power dissipation are compatible. The TE Connectivity part (3-2176090-7) rated at 0.167W (1/6W) exceeds the minimum requirement and is acceptable.

Temperature Coefficient: The main part specifies ±50ppm/°C. Substitute parts with ±25ppm/°C represent improved thermal stability and are compatible upgrades.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original RT0603FRE07309KL.

For standard industrial applications: RT0603BRD07309KL and RT0603DRD07309KL (YAGEO) provide precision improvements while maintaining identical package and power specifications. Both are actively produced with substantial inventory availability.

For automotive or harsh environment applications: ERA-3AEB3093V (Panasonic) and RG1608P-3093-B-T5 (Susumu) carry AEC-Q200 certification. The Susumu part additionally features anti-sulfur coating for enhanced reliability in corrosive environments.

For applications requiring higher power dissipation margin: 3-2176090-7 (TE Connectivity) provides 0.167W rating, offering thermal headroom beyond the 0.1W specification of the original part.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original ±1%? A: Yes. Parts specified at ±0.5% or ±0.1% tolerance are electrically compatible and represent precision upgrades. They will function correctly in circuits designed for ±1% tolerance.

Q: Are all substitute parts pin-compatible with the RT0603FRE07309KL? A: Yes. All listed substitutes use the 0603 (1608 Metric) package with identical two-termination configuration and footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm).

Q: What is the difference between the YAGEO RT series substitutes? A: RT0603BRD07309KL offers ±0.1% tolerance with ±25ppm/°C temperature coefficient. RT0603DRD07309KL provides ±0.5% tolerance, also with ±25ppm/°C. Both are compatible upgrades from the original ±1% / ±50ppm/°C specification.

Q: When should I select an AEC-Q200 certified part? A: AEC-Q200 certification (ERA-3AEB3093V, RG1608P-3093-B-T5) is required for automotive applications or environments with stringent reliability requirements. Standard industrial applications do not require this certification.

Q: Does the TE Connectivity part (3-2176090-7) have different thermal characteristics? A: The TE Connectivity part is rated at 0.167W (1/6W) versus 0.1W for other substitutes, providing additional thermal margin. Temperature coefficient and operating range remain equivalent to other precision substitutes.

Q: Are moisture sensitivity levels identical across all parts? A: Yes. All parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
