Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (549 Ohms), package type (0402/1005 Metric), power rating (0.063W), composition (thin film), and operating temperature range (-55°C to 155°C). Tolerance, temperature coefficient, and manufacturer-specific certifications define upgrade or alternative categories.

Identified substitutes fall into two categories:

Tolerance Upgrade (±0.1%): RT0402BRD07549RL (YAGEO), CPF0402B549RE1 (TE Connectivity), and ERA-2AEB5490X (Panasonic) provide improved tolerance specifications with ±25ppm/°C temperature coefficient.

Automotive-Grade Alternative (±0.5%): RG1005P-5490-D-T10 (Susumu) offers AEC-Q200 automotive qualification and anti-sulfur features with ±25ppm/°C temperature coefficient.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain identical package geometry (0402/1005 Metric), resistance value (549 Ohms), and power rating (0.063W), ensuring direct PCB footprint compatibility.

For standard industrial applications: RT0402BRD07549RL provides tolerance improvement to ±0.1% with reduced temperature coefficient (±25ppm/°C) while maintaining YAGEO series continuity and ROHS3 compliance.

For multi-source procurement: CPF0402B549RE1 (TE Connectivity) offers equivalent ±0.1% tolerance and ±25ppm/°C performance with alternative manufacturer sourcing and ROHS3 compliance.

For automotive applications: ERA-2AEB5490X (Panasonic) and RG1005P-5490-D-T10 (Susumu) both carry AEC-Q200 automotive qualification. ERA-2AEB5490X provides ±0.1% tolerance; RG1005P-5490-D-T10 adds anti-sulfur features with ±0.5% tolerance. Both maintain ROHS3 compliance and -55°C to 155°C operating range.

All substitute parts are ROHS3 compliant with MSL 1 rating and active production status.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07549RL directly replace RT0402FRE07549RL?

A: Yes. Both parts share identical 549 Ohms resistance, 0402 package, 0.063W power rating, and -55°C to 155°C operating range. RT0402BRD07549RL provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). No PCB modifications are required.

Q: What is the difference between tolerance upgrade substitutes?

A: RT0402BRD07549RL, CPF0402B549RE1, and ERA-2AEB5490X all provide ±0.1% tolerance and ±25ppm/°C temperature coefficient. The primary differences are manufacturer (YAGEO, TE Connectivity, Panasonic) and certifications. ERA-2AEB5490X includes AEC-Q200 automotive qualification.

Q: When should I use RG1005P-5490-D-T10?

A: Select RG1005P-5490-D-T10 for automotive applications requiring AEC-Q200 qualification and anti-sulfur protection. Tolerance is ±0.5% with ±25ppm/°C temperature coefficient. Package and power rating remain identical to the main part.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 rating, matching the environmental compliance of RT0402FRE07549RL.

Q: Do substitute parts require PCB layout changes?

A: No. All substitute parts use identical 0402 (1005 Metric) package dimensions: 0.039" L × 0.020" W (1.00mm × 0.50mm). Maximum seated height is 0.014" to 0.016" across all parts. Existing PCB footprints are compatible without modification.
