RT0402FRE07953RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07953RL is a 953 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant and currently in active production status with 919 units in stock.

Substitute parts are identified when electrical specifications (resistance value, power rating, package) and mechanical dimensions remain identical, while tolerance, temperature coefficient, or manufacturer may differ. Alternative sources provide equivalent functionality for applications where the original part is unavailable or where improved specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 953 Ohms
• Power rating: 0.063W (1/16W)
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Allowable Variations:

• Tolerance: May be tighter (±0.1% acceptable for ±1% requirement)
• Temperature coefficient: May be lower (±10ppm/°C to ±50ppm/°C acceptable)
• Manufacturer: Different manufacturers permitted
• Height seated (max): Slight variation acceptable (0.014" to 0.016")

All four substitute parts meet these criteria and are direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance.

RT0402BRD07953RL (YAGEO): Same manufacturer as the main part with improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). Highest inventory availability at 25,070 units. Identical physical dimensions and package specifications.

CPF0402B953RE1 (TE Connectivity): Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Inventory of 3,186 units. Height seated maximum of 0.014" matches primary specification. Suitable for applications requiring cross-manufacturer sourcing.

ERA-2AEB9530X (Panasonic): Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient with AEC-Q200 automotive qualification. Inventory of 20,192 units. Height seated maximum of 0.016" represents acceptable variation within mechanical tolerance stack. Appropriate for automotive or mission-critical applications.

RN73C1E953RBTDF (TE Connectivity): Delivers superior temperature coefficient performance at ±10ppm/°C with ±0.1% tolerance. Inventory of 1,094 units. Lowest temperature coefficient among all options. Suitable for precision analog circuits requiring minimal drift characteristics.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07953RL replace RT0402FRE07953RL directly?

A: Yes. Both parts share identical resistance (953 Ohms), power rating (0.063W), package (0402), operating temperature range (-55°C to 155°C), and physical dimensions. The substitute offers tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally superior for direct substitution.

Q: What is the difference between the substitute parts?

A: All substitutes maintain the same 953 Ohm resistance, 0.063W power rating, and 0402 package. Primary differences are manufacturer, temperature coefficient, and inventory levels. RN73C1E953RBTDF offers the lowest temperature coefficient (±10ppm/°C). ERA-2AEB9530X includes AEC-Q200 automotive qualification. RT0402BRD07953RL and CPF0402B953RE1 provide standard industrial specifications.

Q: Are there any height differences that affect PCB layout?

A: ERA-2AEB9530X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for the other parts. This 0.002" (0.05mm) difference is typically accommodated within standard PCB assembly tolerances but should be verified for applications with tight vertical clearance constraints.

Q: Which substitute offers the best temperature stability?

A: RN73C1E953RBTDF provides the lowest temperature coefficient at ±10ppm/°C, compared to ±25ppm/°C for RT0402BRD07953RL, CPF0402B953RE1, and ERA-2AEB9530X, and ±50ppm/°C for the original RT0402FRE07953RL. This makes RN73C1E953RBTDF optimal for precision analog applications requiring minimal resistance drift across temperature extremes.

Q: Is ERA-2AEB9530X suitable for automotive applications?

A: Yes. ERA-2AEB9530X carries AEC-Q200 automotive qualification, making it appropriate for automotive and mission-critical applications. All other substitutes meet standard industrial specifications.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All parts, including the main component and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
