Substitute Part Grouping Explanation

The substitute part 4-1625868-2 (TE Connectivity Passive Product) qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 14.3 Ohms
• Same package / case: 0805 (2012 Metric)
• Identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Same composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Same number of terminations: 2
• Equivalent RoHS compliance: ROHS3 Compliant
• Equivalent MSL rating: 1 (Unlimited)

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

Parameter Comparison

Engineering Selection Recommendations

The 4-1625868-2 substitute part is suitable for direct replacement in applications currently using the RT0805FRE0714R3L. Both components maintain identical compliance certifications (ROHS3, EAR99 ECCN classification) and equivalent environmental ratings (MSL Level 1). The substitute part's superior tolerance specification (±0.1% vs ±1%) and higher power rating (0.25W vs 0.125W) provide enhanced performance margins without introducing compatibility issues. The marginal height difference (0.026" vs 0.024") remains within standard PCB assembly tolerances for 0805 packages. Selection between these parts should be based on availability, cost considerations, and specific circuit requirements for tolerance and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the 4-1625868-2 be used as a direct replacement for the RT0805FRE0714R3L?

A: Yes. Both parts share identical resistance value, package type (0805), physical dimensions, composition (thin film), and operating temperature range. The substitute part meets or exceeds all critical electrical and mechanical specifications.

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

A: The primary differences are tolerance (±0.1% vs ±1%), power rating (0.25W vs 0.125W), temperature coefficient (±25ppm/°C vs ±50ppm/°C), and maximum seated height (0.026" vs 0.024"). The substitute part offers tighter tolerance and higher power dissipation capability.

Q: Will the slightly different height affect PCB assembly?

A: No. The height difference of 0.002" (0.05mm) is negligible for standard surface mount assembly processes and remains within typical PCB design tolerances for 0805 components.

Q: Are both parts RoHS compliant?

A: Yes. Both the RT0805FRE0714R3L and 4-1625868-2 are ROHS3 compliant with identical MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should I select for high-precision applications?

A: The 4-1625868-2 offers superior tolerance (±0.1%) compared to the RT0805FRE0714R3L (±1%), making it the better choice for applications requiring tighter resistance accuracy.

Q: Are there any thermal performance differences?

A: The 4-1625868-2 has a lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), indicating better resistance stability across temperature variations. Both parts operate across the identical temperature range (-55°C to 155°C).
