Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR1220P-1650-D-M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 165 Ohms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Number of Terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter (lower) than ±0.5%
• Power Rating: May be equal to or higher than 0.1W
• Temperature Coefficient: May be equal to or lower than ±25ppm/°C
• Operating Temperature Range: May extend beyond -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant preferred; non-compliant parts listed for reference only
• Certifications: Additional certifications (AEC-Q200) are acceptable enhancements

Three substitute parts meet these criteria with varying enhancements in tolerance, power rating, temperature range, and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RN73C2A165RBTDF (TE Connectivity Passive Product)

This substitute provides improved tolerance specification (±0.1% versus ±0.5%) while maintaining identical power rating (0.1W) and package dimensions. The temperature coefficient is superior at ±10ppm/°C compared to ±25ppm/°C. Extended operating temperature range to 155°C accommodates high-temperature applications. ROHS3 compliance and REACH Unaffected status match the main part. Height increase from 0.50mm to 0.65mm requires PCB layout verification. Suitable for applications requiring tighter tolerance and improved temperature stability.

ERA-6AEB1650V (Panasonic Electronic Components)

This substitute offers AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. Tolerance is improved to ±0.1%, and operating temperature extends to 155°C. Power rating increases to 0.125W (1/8W), providing additional thermal margin. ROHS3 compliance and REACH Unaffected status are maintained. Height of 0.60mm is intermediate between main part and other substitutes. Select this part for automotive-grade reliability requirements.

4-2176091-5 (TE Connectivity Passive Product)

This substitute provides the highest power rating at 0.25W (1/4W) with ±0.1% tolerance. Extended operating temperature to 155°C is available. However, RoHS non-compliance and undefined REACH status present regulatory concerns. Height increases to 0.65mm. Use only in applications where RoHS exemptions apply or where regulatory compliance is not required.

Frequently Asked Questions (FAQ)

Q: Can RN73C2A165RBTDF replace RR1220P-1650-D-M in all applications?

A: RN73C2A165RBTDF is electrically compatible as a direct substitute. The 0.15mm height increase (0.65mm versus 0.50mm) must be verified against PCB layout constraints and solder reflow profiles. All other mechanical and electrical parameters are compatible.

Q: What is the primary advantage of ERA-6AEB1650V?

A: ERA-6AEB1650V carries AEC-Q200 automotive qualification, which certifies the component for automotive applications requiring enhanced reliability testing and quality assurance. This certification is the primary differentiator for automotive-grade designs.

Q: Why is 4-2176091-5 listed if it is RoHS non-compliant?

A: 4-2176091-5 is included for reference in applications where RoHS exemptions apply or regulatory compliance is not a requirement. The higher power rating (0.25W) may be beneficial in specific thermal management scenarios. Regulatory status must be confirmed before selection.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part format. This ensures compatibility with automated assembly processes.

Q: What is the significance of the temperature coefficient difference between RN73C2A165RBTDF and other parts?

A: RN73C2A165RBTDF has a temperature coefficient of ±10ppm/°C compared to ±25ppm/°C for other parts. This means resistance value changes more slowly with temperature variations, providing superior stability in applications with wide temperature fluctuations or stringent tolerance requirements.

Q: Can substitute parts be mixed in the same design?

A: All substitute parts are mechanically and electrically compatible with the main part specification. However, design consistency and supply chain management typically favor using a single part number per design revision to simplify procurement, testing, and field service.

Q: What PCB layout considerations apply to the height differences?

A: The main part has a maximum seated height of 0.50mm. Substitute parts range from 0.60mm to 0.65mm. Verify that solder paste thickness, reflow profile, and component placement clearances accommodate the taller profile. Consult PCB assembly guidelines and reflow oven specifications.
