Substitute Part Grouping Explanation

The substitute part 7-1625868-4 (TE Connectivity Passive Product) is qualified as a direct substitute based on the following alignment criteria:

• Identical resistance value: 30.9 Ohms
• Identical package / case: 0805 (2012 Metric)
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Identical number of terminations: 2
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)

The substitute part exceeds the main part specifications in tolerance (±0.1% vs ±1%) and power rating (0.25W vs 0.125W), making it suitable for applications requiring equal or higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance. The RT0805FRE0730R9L (YAGEO) is the primary specification. The 7-1625868-4 (TE Connectivity) qualifies as a direct substitute with enhanced performance characteristics: tighter tolerance (±0.1%), higher power rating (0.25W), and lower temperature coefficient (±25ppm/°C). Selection between these parts depends on application requirements and procurement availability. The substitute part's superior specifications support applications with stricter tolerance or thermal dissipation demands within the same 0805 package footprint.

Frequently Asked Questions (FAQ)

Q: Can 7-1625868-4 replace RT0805FRE0730R9L in all applications?

A: Yes. The substitute part maintains identical resistance, package, operating temperature range, and compliance certifications. The enhanced tolerance and power rating do not create incompatibility; they provide additional performance margin.

Q: What is the maximum height difference between these parts?

A: The height difference is 0.002" (0.05mm), with 7-1625868-4 at 0.026" (0.65mm) maximum versus RT0805FRE0730R9L at 0.024" (0.60mm) maximum. This difference is within standard PCB assembly tolerances for 0805 components.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 155°C. The substitute part (7-1625868-4) offers superior temperature stability with ±25ppm/°C coefficient versus ±50ppm/°C for the main part.

Q: Do both parts require identical moisture handling procedures?

A: Yes. Both parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the tolerance impact when substituting?

A: The substitute part provides tighter tolerance (±0.1% vs ±1%), which reduces resistance variation and improves circuit accuracy. This is a performance enhancement, not a limitation.
