RR1220P-1741-D-M Equivalent & Substitute Parts

Part Overview

The RR1220P-1741-D-M is a 1.74 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with an operating temperature range of -55°C to 125°C. The part is Active in product status and ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative manufacturers offer components with matching or superior electrical and mechanical specifications within the same package footprint. Substitutes enable design flexibility, supply chain continuity, and access to components with enhanced performance characteristics such as improved tolerance or extended temperature ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RR1220P-1741-D-M is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 1.74 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Number of Terminations: 2

Allowable Parameter Variations:

• Tolerance: Equal to or better (lower) than ±0.5%
• Power Rating: Equal to or greater than 0.1W
• Temperature Coefficient: Equal to or lower absolute value
• Operating Temperature Range: Equal to or extended beyond -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant or equivalent
• Moisture Sensitivity Level: MSL 1 or lower

All identified substitute parts maintain the 1.74 kOhms resistance value and 0805 package format. Substitutes offer improved tolerance specifications (±0.1% versus ±0.5%) and extended operating temperature ranges (-55°C ~ 155°C). Physical dimensions remain consistent across all alternatives, with height variations within acceptable assembly tolerances.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts are Active in product status and ROHS3 compliant, meeting regulatory requirements equivalent to the main part RR1220P-1741-D-M.

3-2176092-8 (TE Connectivity Passive Product): This substitute offers improved tolerance (±0.1%) and higher power rating (0.25W). Extended operating temperature range (-55°C ~ 155°C) provides thermal margin beyond the main part specification. Height increase to 0.026" (0.65mm) requires verification against PCB assembly clearance constraints.

RN73C2A1K74BTDF (TE Connectivity Passive Product): This substitute matches the power rating (0.1W) and package dimensions of the main part while providing improved tolerance (±0.1%) and superior temperature coefficient (±10ppm/°C). Extended operating temperature range (-55°C ~ 155°C) and increased height (0.026" vs 0.020") are the primary design considerations.

ERA-6AEB1741V (Panasonic Electronic Components): This substitute includes Automotive AEC-Q200 certification, indicating qualification for automotive applications. Improved tolerance (±0.1%), extended temperature range (-55°C ~ 155°C), and reduced power rating (0.125W) are specified. Height of 0.024" (0.60mm) represents a moderate increase from the main part.

RT0805BRD071K74L (YAGEO): This substitute provides improved tolerance (±0.1%) and extended operating temperature range (-55°C ~ 155°C) with power rating of 0.125W. Height specification of 0.024" (0.60mm) requires clearance verification during PCB layout.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RR1220P-1741-D-M with any of these parts directly?

A: All identified substitutes maintain the 1.74 kOhms resistance value and 0805 package footprint, enabling direct PCB footprint compatibility. Physical height variations (0.020" to 0.026") require verification against assembly equipment clearance specifications and PCB design constraints.

Q: What is the primary advantage of using substitute parts?

A: Substitute parts offer improved tolerance specifications (±0.1% versus ±0.5%) and extended operating temperature ranges (-55°C ~ 155°C versus -55°C ~ 125°C). These enhancements provide design margin and supply chain flexibility while maintaining functional equivalence.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the regulatory and environmental specifications of the main part.

Q: Does the RN73C2A1K74BTDF offer any unique advantages?

A: The RN73C2A1K74BTDF features a superior temperature coefficient of ±10ppm/°C compared to ±25ppm/°C for other alternatives. This specification provides enhanced frequency stability and reduced drift characteristics in temperature-sensitive applications.

Q: Is the ERA-6AEB1741V suitable for automotive applications?

A: The ERA-6AEB1741V carries Automotive AEC-Q200 certification, qualifying it for automotive-grade applications. This certification is not present on other substitute options.

Q: What is the impact of increased component height on PCB assembly?

A: Substitute parts with heights of 0.024" to 0.026" (versus 0.020" for the main part) require clearance verification against solder reflow equipment, conformal coating processes, and mechanical assembly constraints. Height increases of 0.004" to 0.006" are typically accommodated within standard PCB assembly tolerances but must be confirmed for specific manufacturing processes.

Q: Can I use the 3-2176092-8 in applications requiring 0.1W power dissipation?

A: Yes. The 3-2176092-8 is rated for 0.25W (1/4W) power dissipation, which exceeds the 0.1W requirement of the main part. This higher rating provides thermal margin and extended component life in power-dissipation-limited applications.

Q: Are there any REACH compliance differences between the main part and substitutes?

A: The main part RR1220P-1741-D-M specifies REACH Unaffected status. Substitute parts RN73C2A1K74BTDF and RT0805BRD071K74L also specify REACH Unaffected. The 3-2176092-8 lists REACH status as Vendor Undefined, requiring clarification from TE Connectivity Passive Product for applications with strict REACH compliance requirements.
