Engineering Selection Recommendations

Primary Recommendation for Direct Replacement:

RT0805CRD074K75L (YAGEO) provides the closest electrical and mechanical match to the RG2012P-4751-C-T5. This part maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Both components are thin film 0805 package resistors with ROHS3 compliance and unlimited moisture sensitivity rating. The RT series is active in production with established supply availability.

Susumu Series Upgrades (Within Same Manufacturer):

For applications where improved performance is acceptable, the following Susumu RG series parts offer tighter tolerance and lower temperature coefficient specifications while maintaining full backward compatibility:

RG2012P-4751-B-T5: Tighter tolerance (±0.1%) with identical temperature coefficient (±25ppm/°C) and AEC-Q200 qualification
RG2012V-4751-B-T5: Enhanced performance with ±0.1% tolerance and ±5ppm/°C temperature coefficient
RG2012V-4751-P-T1: Highest precision option with ±0.02% tolerance and ±5ppm/°C temperature coefficient

All Susumu upgrades maintain 0805 package, 0.125W power rating, -55°C to 155°C operating range, and AEC-Q200 automotive qualification.

Alternative Manufacturer Option:

RP73PF2A4K75BTDF (TE Connectivity) offers higher power rating (0.25W vs. 0.125W) in the same 0805 package. This part is suitable for applications where additional thermal margin is required, though it does not carry AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-4751-C-T5 be replaced with RT0805CRD074K75L?

A: Yes. Both parts share identical electrical specifications (4.75 kΩ ±0.25%, 0.125W, ±25ppm/°C) and mechanical compatibility (0805 package, -55°C to 155°C). The RT0805CRD074K75L is an active production part suitable for direct substitution in existing designs.

Q: What is the difference between Susumu RG series upgrades?

A: The RG series upgrades maintain the same 4.75 kΩ resistance and 0.125W power rating but offer improved tolerance and temperature stability. RG2012P variants maintain ±25ppm/°C temperature coefficient, while RG2012N and RG2012V variants reduce this to ±10ppm/°C and ±5ppm/°C respectively. Tolerance ranges from ±0.25% (original) to ±0.02% (RG2012V-4751-P-T1).

Q: Is AEC-Q200 qualification required for substitution?

A: AEC-Q200 qualification is not mandatory for electrical substitution. However, for automotive applications, components with AEC-Q200 rating provide documented reliability and qualification testing. The Susumu RG series maintains this qualification; TE Connectivity RP73 and YAGEO RT series do not carry this designation.

Q: Can RP73PF2A4K75BTDF be used as a substitute?

A: RP73PF2A4K75BTDF is electrically compatible (4.75 kΩ ±0.1%, ±25ppm/°C, -55°C to 155°C) but rated for 0.25W power dissipation versus the original 0.125W. This higher power rating provides additional thermal margin and is suitable for direct substitution. The component lacks AEC-Q200 qualification.

Q: What packaging formats are available?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The original RG2012P-4751-C-T5 packaging format is not specified in available data but does not affect electrical or mechanical compatibility with TR-packaged equivalents.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the environmental and regulatory requirements of the original component.
