Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

RG1005P-3572-B-T5 (Susumu) is the direct successor to the obsolete RG1005P-3572-B-T1. Both parts share identical electrical specifications (35.7 kΩ, ±0.1%, 0.063W, ±25ppm/°C) and mechanical dimensions. RG1005P-3572-B-T5 is active in production and maintains automotive AEC-Q200 qualification and anti-sulfur coating. This part is the primary replacement for the obsolete RG1005P-3572-B-T1.

CPF0402B35K7E1 (TE Connectivity Passive Product) and RT0402BRD0735K7L (YAGEO) are functionally equivalent alternatives. Both meet the 35.7 kΩ ±0.1% specification in 0402 package with 0.063W power rating and ±25ppm/°C temperature coefficient. CPF0402B35K7E1 is part of the Neohm series. RT0402BRD0735K7L is part of the YAGEO RT series. Both are active products with ROHS3 compliance and MSL 1 rating.

ERA-2AEB3572X (Panasonic Electronic Components) provides direct electrical equivalence with automotive AEC-Q200 qualification. This part maintains the full operating temperature range (-55°C ~ 155°C) and anti-sulfur feature.

MCS04020D3572BE000 (Vishay Beyschlag/Draloric/BC Components) is electrically equivalent with anti-sulfur coating. The operating temperature range is -55°C ~ 125°C, which is narrower than the original specification. This part is suitable for applications not requiring the full 155°C upper temperature limit.

TNPW040235K7BEED (Vishay Dale) offers enhanced power rating (0.13W versus 0.063W) and extended operating temperature range (-55°C ~ 175°C). This part is suitable for applications requiring higher power dissipation or elevated temperature operation while maintaining the 35.7 kΩ ±0.1% specification.

Upgrade Substitutes (Enhanced Specifications):

RG1005N-3572-W-T1 (Susumu) combines tighter tolerance (±0.05% versus ±0.1%) with tighter temperature coefficient (±10ppm/°C). This upgrade is suitable for high-precision analog circuits and measurement applications.

RG1005P-3572-W-T5 (Susumu) provides tighter tolerance (±0.05% versus ±0.1%) while maintaining the standard ±25ppm/°C temperature coefficient. This upgrade is suitable for applications requiring improved resistance accuracy.

Compliance and Certification:

All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Parts with automotive AEC-Q200 qualification (RG1005P-3572-B-T5, RG1005N-3572-B-T5, RG1005N-3572-W-T1, RG1005P-3572-W-T5, ERA-2AEB3572X, TNPW040235K7BEED) are preferred for automotive applications. Non-automotive qualified parts (CPF0402B35K7E1, MCS04020D3572BE000, RT0402BRD0735K7L) are suitable for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-3572-B-T5 be used as a direct replacement for RG1005P-3572-B-T1?

A: Yes. RG1005P-3572-B-T5 is the active production equivalent of the obsolete RG1005P-3572-B-T1. Both parts have identical resistance (35.7 kΩ), tolerance (±0.1%), power rating (0.063W), package (0402), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). Both carry automotive AEC-Q200 qualification and anti-sulfur coating. The only difference is product status (Active versus Obsolete) and packaging format.

Q: What is the difference between Susumu RG series parts and other manufacturers?

A: Susumu RG series parts in this specification set are available in multiple variants. RG1005P series has ±25ppm/°C temperature coefficient, while RG1005N series has ±10ppm/°C. The "W" designation indicates ±0.05% tolerance, while "B" indicates ±0.1% tolerance. All Susumu parts listed maintain automotive AEC-Q200 qualification and anti-sulfur coating. Non-Susumu alternatives (TE Connectivity CPF, Panasonic ERA-2A, Vishay MCS and TNPW, YAGEO RT) provide equivalent electrical performance but may differ in automotive qualification status.

Q: Is TNPW040235K7BEED suitable for the same applications as RG1005P-3572-B-T1?

A: TNPW040235K7BEED is electrically equivalent for resistance, tolerance, and temperature coefficient. However, it has higher power rating (0.13W versus 0.063W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). This part is suitable for applications requiring higher power dissipation or elevated temperature operation. For standard applications matching the original 0.063W specification, this part is over-specified but functionally compatible.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient (ppm/°C) indicates how much the resistance value changes per degree Celsius change in operating temperature. The original RG1005P-3572-B-T1 has ±25ppm/°C. Upgrade options with ±10ppm/°C (RG1005N series) provide better temperature stability, reducing resistance drift across the operating temperature range. This is critical for precision analog circuits, measurement applications, and temperature-sensitive feedback networks.

Q: Can I substitute a part with tighter tolerance (±0.05%) for the original ±0.1% specification?

A: Yes. Tighter tolerance is a superior specification. Parts with ±0.05% tolerance (RG1005N-3572-W-T1, RG1005P-3572-W-T5) can replace ±0.1% parts without functional degradation. The tighter tolerance ensures better resistance accuracy and reduced part-to-part variation, which is beneficial for precision applications.

Q: Are there any package or footprint differences between substitute parts?

A: All parts listed use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm). Height variations are minimal (0.014" to 0.016" / 0.35mm to 0.40mm seated height), which are within standard PCB assembly tolerances. All parts are compatible with standard 0402 land patterns.

Q: Which substitute part should I select for automotive applications?

A: For automotive applications, select parts with AEC-Q200 qualification: RG1005P-3572-B-T5, RG1005N-3572-B-T5, RG1005N-3572-W-T1, RG1005P-3572-W-T5 (Susumu), ERA-2AEB3572X (Panasonic), or TNPW040235K7BEED (Vishay Dale). These parts meet automotive reliability standards. RG1005P-3572-B-T5 is the direct Susumu equivalent. ERA-2AEB3572X and TNPW040235K7BEED provide qualified alternatives from other manufacturers.

Q: What is the difference between anti-sulfur and standard thin film resistors?

A: Anti-sulfur coating protects the resistor element from sulfur contamination in the environment, which can degrade performance and reliability. The original RG1005P-3572-B-T1 includes anti-sulfur coating. Direct Susumu equivalents (RG1005P-3572-B-T5, RG1005N series) and qualified alternatives (ERA-2AEB3572X, MCS04020D3572BE000, TNPW040235K7BEED) maintain this feature. Non-coated alternatives (CPF0402B35K7E1, RT0402BRD0735K7L) are suitable for controlled environments without sulfur exposure.

Q: Can I use CPF0402B35K7E1 or RT0402BRD0735K7L in automotive applications?

A: CPF0402B35K7E1 and RT0402BRD0735K7L do not carry automotive AEC-Q200 qualification. These parts are suitable for industrial and consumer applications but are not recommended for automotive use where AEC-Q200 qualification is required. For automotive applications, use AEC-Q200 qualified parts listed in the Engineering Selection Recommendations section.
