Key Parameters

Substitute Part Grouping Explanation

Substitution for the RT0805FRE07143RL is determined by the following critical parameters:

• Resistance Value: Must be 143 Ohms
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must be 2-terminal configuration
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

Substitute parts may vary in tolerance (±0.1% vs ±1%), power rating (0.25W vs 0.125W), temperature coefficient (±25ppm/°C vs ±50ppm/°C), and automotive qualification (AEC-Q200). These variations represent improvements or enhanced specifications while maintaining functional equivalence in the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

3-2176091-9 (TE Connectivity Passive Product): This substitute offers improved tolerance specification (±0.1% vs ±1%) and increased power rating (0.25W vs 0.125W) while maintaining identical package dimensions and operating temperature range. The TE Connectivity part is ROHS3 compliant with MSL Level 1 rating. Selection of this part is appropriate when enhanced tolerance performance is required within the same thermal and mechanical envelope.

ERA-6AEB1430V (Panasonic Electronic Components): This substitute provides improved tolerance (±0.1%), reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C), and AEC-Q200 automotive qualification. The part maintains the original 0.125W power rating and identical package dimensions. The ERA-6AEB1430V is ROHS3 compliant with MSL Level 1 rating and REACH Unaffected status. Selection of this part is appropriate for applications requiring automotive-grade reliability and tighter tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can the 3-2176091-9 substitute for the RT0805FRE07143RL in all applications?

A: The 3-2176091-9 is mechanically and electrically compatible. The increased power rating (0.25W vs 0.125W) and improved tolerance (±0.1% vs ±1%) represent enhancements. The maximum seated height difference (0.026" vs 0.024") is within typical PCB assembly tolerances for 0805 packages. Compatibility depends on specific circuit requirements and thermal constraints.

Q: What is the advantage of the ERA-6AEB1430V over the original RT0805FRE07143RL?

A: The ERA-6AEB1430V offers three key improvements: tighter tolerance (±0.1% vs ±1%), lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), and AEC-Q200 automotive qualification. These specifications provide enhanced stability across temperature variations and automotive-grade reliability. The package dimensions and power rating remain equivalent.

Q: Are all three parts pin-compatible?

A: Yes. All three parts are 2-terminal thin film chip resistors in 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). They are directly interchangeable at the PCB level without layout modifications.

Q: Which substitute should be selected for cost optimization?

A: Selection based on cost must be balanced against specification requirements. The 3-2176091-9 offers the highest power rating at potentially lower cost per unit. The ERA-6AEB1430V commands a premium due to automotive qualification and tighter tolerance. The original RT0805FRE07143RL remains appropriate when standard tolerance and non-automotive specifications are sufficient.

Q: Do all substitute parts meet the same compliance requirements?

A: All three parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating. The ERA-6AEB1430V has REACH Unaffected status. The TE Connectivity part lists REACH status as Vendor Undefined. All parts carry EAR99 ECCN classification and identical HTSUS codes.
