RT0402FRE0728RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE0728RL is a 28 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The component is ROHS3 compliant and carries MSL Level 1 rating, indicating unlimited moisture sensitivity protection. As an active product with established supply availability, substitute parts may be required for design optimization, enhanced performance specifications, or supply chain flexibility.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0728RL is determined by strict equivalence in the following parameters:

• Resistance value: 28 Ohms (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Power rating: 0.063W minimum (equal or greater acceptable)
• Operating temperature range: -55°C to 155°C minimum (equal or greater range acceptable)
• RoHS compliance: ROHS3 or equivalent (required)
• MSL rating: Level 1 or better (required)

The CPF0402B28RE1 qualifies as a direct substitute based on these criteria. Enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance upgrades rather than substitution barriers.

Parameter Comparison

Engineering Selection Recommendations

Both components meet identical mechanical and environmental requirements. The RT0402FRE0728RL and CPF0402B28RE1 are fully interchangeable at the PCB assembly level. Selection between these parts should be based on:

• Supply chain availability and lead time requirements
• Cost considerations between YAGEO and TE Connectivity sourcing
• Design margin requirements: CPF0402B28RE1 offers tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) for applications requiring enhanced stability
• Inventory management: existing stock levels and procurement logistics

Both components carry active product status and full RoHS3 compliance with Level 1 MSL rating, ensuring equivalent reliability and regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B28RE1 be used as a direct replacement for RT0402FRE0728RL?

A: Yes. Both components share identical resistance value (28 Ohms), package type (0402), power rating (0.063W), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL Level 1). Physical dimensions and termination count are identical, enabling direct PCB substitution.

Q: What are the differences between these two parts?

A: The primary differences are tolerance and temperature coefficient. CPF0402B28RE1 provides ±0.1% tolerance compared to ±1% for RT0402FRE0728RL, and a temperature coefficient of ±25ppm/°C versus ±50ppm/°C. These represent performance enhancements rather than compatibility limitations.

Q: Are there any package or footprint considerations?

A: No. Both components use identical 0402 (1005 Metric) packaging with matching physical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and maximum seated height (0.014" / 0.35mm). PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RT0402FRE0728RL and CPF0402B28RE1 are ROHS3 compliant with MSL Level 1 rating. They carry identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: Which part should be selected for high-precision applications?

A: CPF0402B28RE1 is suitable for applications requiring tighter tolerance control and improved temperature stability due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient.
