RoHS3 compliance

Allowable Variation Parameters:

Tolerance: ±0.25% or tighter (±0.1%, ±0.05%)
Temperature coefficient: ±25ppm/°C or tighter (±10ppm/°C)
Automotive rating: AEC-Q200 preferred but not mandatory for direct electrical substitution

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Preferred for Direct Replacement):

RG1608N-1433-B-T5 and RG1608P-1433-B-T5 are the recommended primary substitutes. Both parts maintain the same manufacturer (Susumu), identical package format, and AEC-Q200 automotive rating. RG1608N-1433-B-T5 offers improved tolerance (±0.1%) and tighter temperature coefficient (±10ppm/°C) with active product status. RG1608P-1433-B-T5 maintains the original temperature coefficient specification (±25ppm/°C) while improving tolerance to ±0.1%.

Enhanced Performance Alternatives (Susumu RG Series):

RG1608N-1433-W-T1 and RG1608P-1433-W-T1 provide the highest tolerance specification (±0.05%) available within the Susumu RG series. These parts are suitable for applications requiring tighter resistance tolerances while maintaining full AEC-Q200 compliance and automotive-grade construction.

Cross-Manufacturer Substitutes (Active Production):

ERA-3AEB1433V (Panasonic) provides equivalent electrical specifications with ±0.1% tolerance and maintains AEC-Q200 automotive rating. This part offers the highest inventory availability (55,164 units) among all substitutes.

RT0603BRD07143KL (YAGEO) matches the original tolerance (±0.25%) and power rating with ±0.1% tolerance upgrade option. This part does not carry AEC-Q200 rating but maintains full electrical compatibility for non-automotive applications.

2176090-5 (TE Connectivity) provides higher power rating (0.167W) with ±0.1% tolerance. This part is suitable for applications where increased power dissipation capability is beneficial, though it lacks AEC-Q200 certification.

Selection Criteria:

For automotive applications requiring AEC-Q200 compliance, select from Susumu RG series (RG1608N-1433-B-T5, RG1608P-1433-B-T5, RG1608N-1433-W-T1, RG1608P-1433-W-T1) or Panasonic ERA-3AEB1433V.

For general industrial applications without automotive requirements, YAGEO RT0603BRD07143KL or RT0603CRD07143KL provide cost-effective alternatives with equivalent electrical performance.

For applications requiring enhanced power dissipation, TE Connectivity 2176090-5 offers 0.167W rating while maintaining 143 kOhms resistance and ±0.1% tolerance.

Frequently Asked Questions (FAQ)

Q: Can RG1608P-1433-C-T5 be replaced with RG1608N-1433-B-T5?

A: Yes. Both parts share identical resistance (143 kOhms), package format (0603), power rating (0.1W), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive rating. RG1608N-1433-B-T5 provides improved tolerance (±0.1% versus ±0.25%) and tighter temperature coefficient (±10ppm/°C versus ±25ppm/°C). The primary difference is packaging format: RG1608P-1433-C-T5 is supplied in bulk, while RG1608N-1433-B-T5 is supplied in Tape & Reel format.

Q: What is the difference between Susumu RG1608N and RG1608P series?

A: The RG1608N series features tighter temperature coefficient specifications (±10ppm/°C) compared to the RG1608P series (±25ppm/°C). Both series maintain identical resistance values, package formats, and AEC-Q200 ratings. Selection between series depends on application requirements for temperature stability.

Q: Can non-AEC-Q200 parts substitute for automotive applications?

A: Non-AEC-Q200 parts (YAGEO RT series) match the core electrical specifications but lack automotive-grade certification. Use of non-certified parts in automotive applications requires design review and qualification testing per applicable automotive standards.

Q: Is the TE Connectivity 2176090-5 a direct replacement?

A: 2176090-5 provides electrical equivalence with 143 kOhms resistance, ±0.1% tolerance, and 0603 package format. The primary difference is higher power rating (0.167W versus 0.1W). This part lacks AEC-Q200 certification. It is suitable for applications where the original 0.1W rating is adequate and automotive certification is not required.

Q: What is the impact of tolerance differences on circuit performance?

A: Tolerance specifications define the maximum deviation from nominal resistance value. ±0.25% tolerance allows ±357.5 Ohms deviation from 143 kOhms nominal. ±0.1% tolerance allows ±143 Ohms deviation. ±0.05% tolerance allows ±71.5 Ohms deviation. Applications requiring precise resistance values benefit from tighter tolerance specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original RG1608P-1433-C-T5 specification.

Q: What packaging format should be selected for manufacturing?

A: Tape & Reel (TR) packaging is standard for automated assembly processes. Bulk packaging is typically used for manual assembly or repair applications. All active substitute parts are available in Tape & Reel format.

Q: Can Panasonic ERA-3AEB1433V replace the Susumu part in existing designs?

A: Yes. ERA-3AEB1433V matches all critical parameters: 143 kOhms resistance, 0603 package, 0.1W power rating, -55°C to 155°C operating range, and AEC-Q200 automotive rating. The part is electrically and mechanically compatible with identical footprint and performance characteristics.
