RT0402FRE0723R2L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0723R2L is a 23.2 Ohm thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package format. This component is rated at 1/16W (0.063W) with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 rating, making it suitable for high-reliability applications requiring stable resistance values across extended temperature ranges.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when design requirements demand tighter tolerance specifications, or when supply chain optimization requires alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0723R2L is determined by the following critical parameters:

• Resistance Value: Must be 23.2 Ohms (exact match required)
• Package Format: Must be 0402 (1005 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be ≥0.063W (1/16W) to meet or exceed thermal dissipation requirements
• Composition: Thin film construction ensures performance characteristics align with the original specification
• Operating Temperature Range: Must span -55°C to 155°C minimum
• Termination Count: Must be 2-terminal configuration
• Compliance: Must maintain ROHS3 compliance and MSL Level 1 or better

The CPF0402B23R2E1 qualifies as a direct substitute because it matches all critical parameters while offering enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), representing an upgrade path for applications requiring tighter specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0402FRE0723R2L and CPF0402B23R2E1 maintain Active product status and satisfy ROHS3 compliance requirements with MSL Level 1 ratings, confirming their suitability for production applications.

The RT0402FRE0723R2L serves as the primary specification component with established supply availability (1022 pcs in stock).

The CPF0402B23R2E1 functions as an upgrade substitute, offering superior tolerance performance (±0.1% versus ±1%) and reduced temperature coefficient drift (±25ppm/°C versus ±50ppm/°C). This substitute is appropriate for applications where tighter resistance accuracy or improved thermal stability is required. Current inventory availability is 1581 pcs.

Selection between these parts should be based on application tolerance requirements and thermal performance specifications rather than functional interchangeability, as both components satisfy the core electrical and mechanical requirements of the 0402 thin film resistor category.

Frequently Asked Questions (FAQ)

Q: Can the CPF0402B23R2E1 be used as a direct replacement for the RT0402FRE0723R2L?

A: Yes. Both components share identical resistance values (23.2 Ohms), package format (0402), power rating (1/16W), operating temperature range (-55°C to 155°C), and physical dimensions. The CPF0402B23R2E1 represents an upgrade due to tighter tolerance and improved temperature coefficient specifications.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance specification (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). Both differences favor the CPF0402B23R2E1 for applications requiring enhanced precision and thermal stability.

Q: Are there any package or footprint compatibility concerns?

A: No. Both components use the identical 0402 (1005 Metric) package with matching physical dimensions (0.039" L x 0.020" W, height 0.014" max). PCB footprints are fully compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RT0402FRE0723R2L and CPF0402B23R2E1 are ROHS3 compliant with MSL Level 1 ratings, confirming equivalent environmental and reliability compliance.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard tolerance applications, either part is acceptable. For applications requiring tighter resistance accuracy or superior temperature stability, the CPF0402B23R2E1 is the preferred choice.
