Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory criteria:

• Identical resistance value: 17.8 Ohms
• Identical package / case: 0603 (1608 Metric)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical number of terminations: 2
• Identical RoHS compliance status: ROHS3 Compliant
• Identical moisture sensitivity level: 1 (Unlimited)

Tolerance, power rating, and temperature coefficient may vary within acceptable engineering parameters for the application. Substitute parts identified below meet all mandatory criteria and represent direct electrical and mechanical equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the RT0603FRE0717R8L in terms of package, thermal range, and regulatory compliance. Selection between alternatives depends on application-specific requirements:

RT0603DRE0717R8L offers improved tolerance (±0.5% versus ±1%) while maintaining identical power rating and temperature coefficient, suitable for applications requiring tighter resistance accuracy within the same thermal performance envelope.

RP73PF1J17R8BTDF provides enhanced tolerance (±0.1%), superior temperature coefficient (±25ppm/°C versus ±50ppm/°C), and increased power rating (0.167W versus 0.1W) from TE Connectivity. This part accommodates higher power dissipation and delivers superior temperature stability, appropriate for precision applications with elevated thermal demands.

All three parts are ROHS3 compliant and carry MSL 1 rating, confirming suitability for standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0603DRE0717R8L be used as a direct replacement for RT0603FRE0717R8L?

A: Yes. Both parts share identical resistance, package, power rating, temperature range, and compliance specifications. The RT0603DRE0717R8L features improved tolerance (±0.5% versus ±1%), making it a direct upgrade with enhanced accuracy.

Q: What are the key differences between RP73PF1J17R8BTDF and the YAGEO alternatives?

A: RP73PF1J17R8BTDF is manufactured by TE Connectivity and offers three performance enhancements: tighter tolerance (±0.1%), lower temperature coefficient (±25ppm/°C), and higher power rating (0.167W). Physical dimensions are marginally smaller (1.55mm length versus 1.60mm), though both remain within 0603 package specifications.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No. All three parts conform to 0603 (1608 Metric) package specifications with identical height (0.022" maximum seated height) and termination count (2). Dimensional variations are within standard package tolerances and do not affect PCB layout or assembly processes.

Q: Which substitute part should be selected for high-precision applications?

A: RP73PF1J17R8BTDF is recommended for precision applications due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient, providing superior resistance stability across the operating temperature range.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT0603DRE0717R8L and RP73PF1J17R8BTDF are both ROHS3 compliant with MSL 1 rating, matching the compliance profile of the original RT0603FRE0717R8L.
