Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE072K49L are qualified based on the following criteria:

• Identical resistance value: 2.49 kOhms
• Identical package format: 0805 (2012 Metric)
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Identical composition: Thick Film
• Identical temperature coefficient: ±50ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The substitute parts identified are manufactured by Panasonic Electronic Components (ERJ-PB series). These substitutes maintain all critical mechanical and thermal parameters while offering enhanced tolerance specifications (±0.1% and ±0.5%) and increased power ratings (0.25W / 1/4W). Both substitutes include AEC-Q200 automotive qualification and pulse withstanding capability.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB series substitutes maintain full compatibility with the RE0805FRE072K49L in terms of mechanical fit, thermal performance, and regulatory compliance. The ERJ-PB6B2491V offers the tightest tolerance specification at ±0.1%, suitable for precision circuit applications. The ERJ-PB6D2491V provides a balanced tolerance of ±0.5% with significantly higher inventory availability (45,667 units in stock). Both substitutes feature AEC-Q200 automotive qualification and pulse withstanding characteristics, extending application scope beyond the original part specification. The increased power rating (0.25W versus 0.125W) in both substitutes provides additional thermal margin in power-dissipation-sensitive designs. All three parts maintain identical ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B2491V and ERJ-PB6D2491V be used interchangeably with RE0805FRE072K49L?

A: Both Panasonic parts are mechanically and electrically compatible substitutes. The primary differences are tolerance grade (±0.1% and ±0.5% respectively versus ±1%) and power rating (0.25W versus 0.125W). Selection depends on circuit tolerance requirements and thermal design margins.

Q: What is the impact of the increased height specification (0.028" versus 0.024")?

A: The 0.004" (0.10mm) height difference is within typical PCB assembly tolerances for 0805 components. Verify clearance in space-constrained applications, particularly in multi-layer assemblies or designs with minimal component-to-component spacing.

Q: Are the Panasonic substitutes suitable for automotive applications?

A: Yes. Both ERJ-PB6B2491V and ERJ-PB6D2491V carry AEC-Q200 automotive qualification, making them suitable for automotive-grade circuit designs. The original RE0805FRE072K49L does not specify automotive qualification.

Q: How do tolerance differences affect circuit performance?

A: The ±0.1% tolerance of ERJ-PB6B2491V provides superior accuracy for precision analog circuits and reference networks. The ±0.5% tolerance of ERJ-PB6D2491V is suitable for general-purpose applications where the original ±1% tolerance is acceptable. Tolerance selection should align with circuit design specifications.

Q: Are there any handling or storage differences between these parts?

A: All three parts share identical MSL 1 (Unlimited) ratings, indicating no moisture sensitivity restrictions. Handling, storage, and reflow procedures are equivalent across all three components.
