RG1005P-302-C-T10 Equivalent & Substitute Parts

Part Overview

The RG1005P-302-C-T10 is a 3 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated for 0.063W (1/16W) power dissipation. Manufactured by Susumu with anti-sulfur coating and automotive AEC-Q200 qualification, this component is designed for high-precision applications requiring tight tolerance and temperature stability across the -55°C to 155°C operating range.

The RG1005P-302-C-T10 is classified as obsolete. Equivalent and substitute parts are available from multiple manufacturers with improved specifications or enhanced availability, making substitution necessary for new designs and ongoing production requirements.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Same Manufacturer):

The RG1005P-302-B-T5 is the direct active equivalent with identical tolerance (±0.25%) and temperature coefficient (±25ppm/°C) specifications. This part maintains full compatibility with the original RG1005P-302-C-T10 design requirements while offering active product status and significantly higher inventory availability (42,572 units).

The RG1005N-302-B-T5 and RG1005N-302-W-T5 provide enhanced tolerance specifications (±0.1% and ±0.05% respectively) with improved temperature coefficient performance (±10ppm/°C for RG1005N series). These upgrades are suitable for applications requiring tighter tolerance control without design modification.

Cross-Manufacturer Substitutes (Automotive AEC-Q200 Rated):

The ERA-2AEB302X from Panasonic maintains automotive AEC-Q200 qualification equivalent to the original part. This substitute provides ±0.1% tolerance with active product status and substantial inventory (59,327 units).

Cross-Manufacturer Substitutes (General Industrial):

The RT0402BRD073KL from YAGEO and CPF0402B3K0E1 from TE Connectivity provide ±0.1% tolerance specifications with active status. These parts are suitable for applications where automotive AEC-Q200 qualification is not required.

The MCS04020D3001BE100 from Vishay Beyschlag offers ±0.1% tolerance with anti-sulfur coating. Note that the operating temperature range is limited to -55°C to 125°C, which is narrower than the original specification of -55°C to 155°C.

Selection Criteria:

For direct replacement with identical specifications: RG1005P-302-B-T5
For automotive applications requiring AEC-Q200: ERA-2AEB302X
For improved tolerance without design change: RG1005N-302-B-T5 or RG1005N-302-W-T5
For general industrial applications: RT0402BRD073KL or CPF0402B3K0E1

All recommended substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited) and maintain the 0402 package footprint.

Frequently Asked Questions (FAQ)

Q: Can the RG1005P-302-B-T5 be used as a direct replacement for the RG1005P-302-C-T10?

A: Yes. The RG1005P-302-B-T5 maintains identical electrical specifications: 3 kOhms resistance, ±0.25% tolerance, ±25ppm/°C temperature coefficient, and 0.063W power rating. Both parts use the same 0402 package, have identical operating temperature range (-55°C to 155°C), and carry AEC-Q200 automotive qualification. The primary difference is product status: RG1005P-302-B-T5 is active with high inventory availability.

Q: What is the difference between RG1005N and RG1005P series?

A: The RG1005N series offers improved temperature coefficient performance (±10ppm/°C) compared to the RG1005P series (±25ppm/°C). The RG1005N series also provides tighter tolerance options (±0.05% and ±0.1%) versus the RG1005P series (±0.25% and ±0.1%). Both series maintain the same 0402 package, power rating, and operating temperature range. Selection depends on application requirements for temperature stability and tolerance precision.

Q: Are cross-manufacturer parts electrically equivalent?

A: Cross-manufacturer substitutes from YAGEO, Panasonic, TE Connectivity, and Vishay Beyschlag are electrically equivalent when specifications match: 3 kOhms resistance, ±0.1% or ±0.25% tolerance, 0.063W power rating, and 0402 package. All listed substitutes maintain the -55°C to 155°C operating range except MCS04020D3001BE100, which is limited to -55°C to 125°C. Verify automotive AEC-Q200 requirement for your application before selection.

Q: Does the MCS04020D3001BE100 have any limitations?

A: The MCS04020D3001BE100 has a reduced maximum operating temperature of 125°C compared to the original specification of 155°C. This part is suitable only for applications where the upper operating temperature does not exceed 125°C. All other electrical and mechanical parameters are compatible.

Q: What is the significance of anti-sulfur coating?

A: Anti-sulfur coating is specified for the original RG1005P-302-C-T10 and is present in the RG1005N and RG1005P Susumu series, as well as the MCS04020D3001BE100 from Vishay Beyschlag. This feature provides enhanced reliability in environments with sulfur-containing contaminants. For applications without sulfur exposure concerns, parts without this coating (YAGEO RT series, TE Connectivity CPF series, Panasonic ERA-2A series) are functionally equivalent.

Q: Can I use a part with tighter tolerance than specified?

A: Yes. A substitute part with tighter tolerance (±0.1% or ±0.05%) can replace a part specified at ±0.25% without design modification. Tighter tolerance provides improved circuit performance and stability. Conversely, a part with looser tolerance cannot replace a tighter tolerance specification.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the original RG1005P-302-C-T10 environmental compliance status.

Q: What packaging options are available?

A: The original RG1005P-302-C-T10 is specified with tape and reel (TR) packaging. All active substitute parts listed are supplied in tape and reel format, suitable for automated assembly processes.
