RT0603CRE07309RL Equivalent & Substitute Parts

Part Overview

The RT0603CRE07309RL is a 309 Ohm thin film chip resistor manufactured by YAGEO in the 0603 (1608 Metric) package format. This component is rated for 0.1W power dissipation with ±0.25% tolerance and operates across the temperature range of -55°C to 155°C. The part is currently active in production and available in tape and reel packaging. Equivalent and substitute parts are identified when design requirements necessitate alternative manufacturers, improved tolerance specifications, enhanced reliability ratings, or increased power handling capabilities while maintaining the same resistance value and package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603CRE07309RL is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value: 309 Ohms (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (equal or better status acceptable)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±0.25%
• Temperature coefficient: May be equal to or lower than ±50ppm/°C
• Power rating: May be equal to or higher than 0.1W
• Certifications: Additional certifications (AEC-Q200, Anti-Sulfur) are allowable enhancements

The three substitute parts listed below meet all primary substitution parameters and represent upgrades in tolerance, temperature stability, or reliability ratings.

Parameter Comparison

Engineering Selection Recommendations

ERA-3AEB3090V (Panasonic Electronic Components): This substitute provides tighter tolerance (±0.1% versus ±0.25%), improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), and AEC-Q200 automotive qualification. The part maintains identical power rating and package specifications. Selection is appropriate for applications requiring enhanced precision and automotive-grade reliability.

RG1608P-3090-B-T5 (Susumi): This substitute offers tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), AEC-Q200 automotive qualification, and anti-sulfur protection. The seated height is marginally reduced (0.020" versus 0.022"). Selection is appropriate for automotive applications or environments with corrosive exposure where anti-sulfur protection is beneficial.

RP73PF1J309RBTDF (TE Connectivity Passive Product): This substitute provides tighter tolerance (±0.1%), improved temperature coefficient (±25ppm/°C), and increased power rating (0.167W versus 0.1W). The physical dimensions are slightly reduced (1.55mm length versus 1.60mm). Selection is appropriate for applications requiring higher power dissipation capability or where space constraints favor the reduced footprint.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB3090V be used as a direct replacement for RT0603CRE07309RL?

A: Yes. Both parts share identical resistance value (309 Ohms), package format (0603), composition (thin film), and operating temperature range (-55°C to 155°C). The ERA-3AEB3090V provides superior tolerance and temperature stability, making it a compatible upgrade.

Q: What is the primary difference between RG1608P-3090-B-T5 and the other substitutes?

A: RG1608P-3090-B-T5 includes anti-sulfur protection in addition to AEC-Q200 automotive qualification. This feature is relevant for applications exposed to sulfur-containing environments. The seated height is also marginally lower at 0.020" compared to 0.022" for the original part.

Q: Is RP73PF1J309RBTDF suitable for higher power applications?

A: RP73PF1J309RBTDF is rated for 0.167W (1/6W) compared to the original 0.1W (1/10W) rating. This higher power rating allows for greater current handling capability. However, the physical package remains 0603 (1608 Metric), so thermal management considerations should be evaluated for the specific application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts are ROHS3 compliant, matching the compliance status of the original RT0603CRE07309RL.

Q: What does the ±0.1% tolerance improvement mean in practical terms?

A: The substitute parts with ±0.1% tolerance provide twice the precision of the original ±0.25% tolerance. For a 309 Ohm resistor, this represents a tolerance band of ±0.309 Ohms versus ±0.7725 Ohms, resulting in tighter resistance value distribution across production batches.

Q: Can these substitutes be used interchangeably on the same PCB?

A: Yes. All substitute parts maintain the 0603 (1608 Metric) package format with compatible footprints. Physical dimensions are within acceptable tolerances for standard PCB assembly processes. Verify specific design requirements for any height-sensitive applications, as seated heights range from 0.020" to 0.022".
