RN731ETTP2000F25 Equivalent & Substitute Parts

Part Overview

The RN731ETTP2000F25 is a 200 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package rated at 1/16W (0.063W) power dissipation. Manufactured by KOA Speer Electronics, Inc., this component is classified as obsolete. The RN73 series offers moisture-resistant construction with ±25ppm/°C temperature coefficient and operates across -55°C to 155°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers provide continuity for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (200 Ohms), package type (0402), power rating (1/16W), composition (thin film), temperature coefficient (±25ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH). Tolerance variations are permitted where tighter tolerances (±0.1%, ±0.25%, ±0.5%) represent upgrades to the original ±1% specification. All substitute parts maintain identical mechanical dimensions and electrical performance within the specified operating envelope.

Direct equivalents maintain the original ±1% tolerance. Upgrade substitutes offer improved tolerance specifications (±0.1%, ±0.25%, ±0.5%) while preserving all other electrical and mechanical characteristics. Additional features such as automotive AEC-Q200 certification and anti-sulfur construction are noted where applicable but do not affect functional substitutability.

Engineering Selection Recommendations

For direct replacement of the obsolete RN731ETTP2000F25, the RN73R1ETTP2000F25 from KOA Speer Electronics provides identical electrical specifications with active product status and automotive AEC-Q200 certification. This maintains design continuity with the original component family.

The RT0402FRD07200RL from YAGEO offers a functionally equivalent alternative with active status and identical tolerance specification. This part is suitable for applications where manufacturer diversity is required.

Upgrade substitutes with improved tolerance specifications (±0.1%, ±0.25%, ±0.5%) are available from YAGEO (AT series), TE Connectivity (CPF series), and Panasonic (ERA-2A series). These parts maintain all electrical and mechanical compatibility while providing enhanced precision. Parts with automotive AEC-Q200 certification (AT0402BRD07200RL, AT0402CRD07200RL, AT0402DRD07200RL, CPF-A-0402B200RE, CPF-A-0402B200RE1, ERA-2AEB201X) are suitable for automotive and high-reliability applications. Non-automotive variants (CPF0402B200RE, CPF0402B200RE1) are suitable for general industrial applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original ±1%? A: Yes. Parts with ±0.1%, ±0.25%, or ±0.5% tolerance are direct upgrades and maintain full compatibility. Tighter tolerance specifications do not affect mechanical fit or electrical performance in circuits designed for ±1% tolerance.

Q: What is the difference between automotive AEC-Q200 certified parts and non-certified variants? A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. Parts with this certification (RN73R1ETTP2000F25, AT0402BRD07200RL, AT0402CRD07200RL, AT0402DRD07200RL, CPF-A-0402B200RE, CPF-A-0402B200RE1, ERA-2AEB201X) are suitable for automotive applications. Non-certified parts are suitable for general industrial use.

Q: Are all substitute parts in the same 0402 package? A: Yes. All listed substitute parts use the 0402 (1005 Metric) package with identical mechanical dimensions (0.039" L × 0.020" W, 1.00mm × 0.50mm) and maximum seated height specifications. They are mechanically interchangeable on PCBs designed for 0402 components.

Q: What does anti-sulfur construction mean? A: Anti-sulfur construction provides enhanced resistance to sulfur-containing environmental contaminants. This feature is present in YAGEO AT series and TE Connectivity CPF-A series parts but is not required for functional substitution.

Q: Is the RN731ETTP2000F25 still available? A: The RN731ETTP2000F25 is classified as obsolete. The active equivalent RN73R1ETTP2000F25 from the same manufacturer is recommended for new designs and ongoing production.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All listed parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
