Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR01J33RTB is determined by strict equivalence across the following parameters:

Core Electrical Parameters: Resistance value (33 Ohms), tolerance (±5%), and power rating (1W) must be identical across all substitute parts.

Physical Form Factor: All substitute parts must utilize axial through-hole package configuration with two terminations to ensure mechanical compatibility with existing PCB layouts and assembly processes.

Material Composition: Metal film construction is required for all substitutes to maintain electrical performance characteristics and thermal stability.

Compliance Requirements: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory and supply chain requirements.

Operating Temperature: Substitute parts must support a minimum operating temperature range of -55°C to 155°C. The main part RR01J33RTB extends to 235°C; however, substitutes operating to 155°C remain functionally compatible for standard industrial applications.

The identified substitute parts—FMP100JR-52-33R (YAGEO) and PR01000103309JR500 (Vishay Beyschlag/Draloric/BC Components)—satisfy all core substitution criteria while offering alternative sourcing options and application-specific certifications.

Parameter Comparison

Engineering Selection Recommendations

RR01J33RTB (TE Connectivity Passive Product): Primary selection for applications requiring extended operating temperature capability to 235°C. Flame retardant coating and pulse withstanding features provide enhanced reliability in high-stress electrical environments. Suitable for general industrial and commercial applications with standard thermal requirements.

FMP100JR-52-33R (YAGEO): Alternative sourcing option with highest available inventory (16,205 pcs). Flame proof construction and compact physical dimensions (0.094" diameter) accommodate space-constrained PCB layouts. Operating temperature range to 155°C satisfies standard industrial specifications. Appropriate for cost-optimized designs with standard thermal profiles.

PR01000103309JR500 (Vishay Beyschlag/Draloric/BC Components): Designated substitute for automotive and mission-critical applications requiring AEC-Q200 qualification. Fusible feature and flame retardant coating provide enhanced safety characteristics. Temperature coefficient specification (±250ppm/°C) enables precision circuit design. Highest inventory availability (23,124 pcs) supports high-volume production requirements.

All three parts maintain Active product status, ensuring long-term availability and supply chain stability. Selection between alternatives depends on application-specific requirements for temperature range, automotive certification, and physical form factor constraints.

Frequently Asked Questions (FAQ)

Q: Can FMP100JR-52-33R or PR01000103309JR500 be used as direct replacements for RR01J33RTB in all applications?

A: Both substitute parts are electrically and mechanically compatible for applications operating within the -55°C to 155°C temperature range. Applications requiring operation above 155°C must retain the RR01J33RTB. Physical dimensions vary slightly; verify PCB layout clearances before substitution.

Q: What is the significance of the AEC-Q200 certification on the PR01000103309JR500?

A: AEC-Q200 certification indicates qualification for automotive applications under controlled environmental and stress conditions. This certification is required for automotive circuit designs but is not necessary for general industrial or commercial applications.

Q: Are there differences in reliability or failure characteristics between these three parts?

A: All three parts are metal film resistors with identical electrical specifications (33 Ohms, ±5%, 1W). Reliability differences relate to application-specific features: RR01J33RTB provides pulse withstanding capability; FMP100JR-52-33R offers flame proof construction; PR01000103309JR500 includes fusible characteristics and automotive qualification. Selection should align with application requirements.

Q: How do physical dimension differences affect PCB design?

A: The three parts have similar but distinct axial dimensions. FMP100JR-52-33R is the most compact (0.094" diameter), while RR01J33RTB is the largest (0.102" diameter). Verify PCB hole spacing and component clearance specifications before substitution. Axial package compatibility remains consistent across all three parts.

Q: What compliance certifications apply to all three substitute parts?

A: All three parts maintain RoHS3 compliance and REACH unaffected status. These certifications ensure regulatory compliance for EU and international markets. PR01000103309JR500 additionally carries AEC-Q200 automotive qualification.

Q: Is inventory availability a factor in part selection?

A: Inventory levels are provided for reference: RR01J33RTB (3,939 pcs), FMP100JR-52-33R (16,205 pcs), and PR01000103309JR500 (23,124 pcs). Higher inventory availability may reduce lead times for high-volume production requirements or urgent sourcing needs.
