Engineering Selection Recommendations

Direct Replacement (Identical Specifications):

RT0402CRD072K94L (YAGEO) provides direct electrical equivalence with matching ±0.25% tolerance and ±25ppm/°C temperature coefficient. This part is active and ROHS3 compliant. The primary distinction is the absence of automotive AEC-Q200 qualification and anti-sulfur coating; however, electrical performance is identical to the original specification.

Upgraded Susumu RG Series (Active Status, Enhanced Performance):

RG1005P-2941-B-T5 and RG1005P-2941-W-T5 maintain the original ±25ppm/°C temperature coefficient while offering improved tolerance (±0.1% and ±0.05% respectively). Both retain full AEC-Q200 automotive qualification and anti-sulfur features. These parts are direct mechanical and functional upgrades with tighter tolerance specifications.

RG1005V series parts (RG1005V-2941-B-T5, RG1005V-2941-P-T1, RG1005V-2941-W-T1) provide superior temperature stability with ±5ppm/°C coefficient and tolerance options from ±0.1% to ±0.02%. All maintain AEC-Q200 qualification and anti-sulfur coating. These represent the highest-performance alternatives within the Susumu RG portfolio.

Cross-Manufacturer Alternatives (Active Status):

ERA-2AEB2941X (Panasonic ERA-2A series) offers ±0.1% tolerance with AEC-Q200 automotive qualification and anti-sulfur coating, matching the original feature set while improving tolerance specification. This part is widely available with 10,334 units in stock.

CPF0402B2K94E1 (TE Connectivity Neohm series) provides ±0.1% tolerance in active production status. This part lacks automotive qualification but delivers equivalent electrical performance for non-automotive applications.

Product Status Consideration:

All substitute parts listed are in active production status, ensuring long-term availability and supply chain continuity. The original RG1005P-2941-C-T10 is obsolete; migration to an active alternative is necessary for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-2941-B-T5 directly replace RG1005P-2941-C-T10 in existing designs?

A: Yes. RG1005P-2941-B-T5 is mechanically and electrically compatible. Both parts share identical 2.94 kOhms resistance, 0.063W power rating, 0402 package, and -55°C to 155°C operating range. The substitute offers improved ±0.1% tolerance versus the original ±0.25%, and both maintain ±25ppm/°C temperature coefficient and AEC-Q200 automotive qualification. No circuit redesign is required.

Q: What is the difference between RG1005N, RG1005P, and RG1005V series?

A: These designations indicate different temperature coefficient specifications. RG1005N series features ±10ppm/°C, RG1005P series features ±25ppm/°C, and RG1005V series features ±5ppm/°C. All three series are available with identical 2.94 kOhms resistance and 0402 package. Selection depends on application temperature stability requirements.

Q: Is ERA-2AEB2941X suitable for automotive applications?

A: Yes. ERA-2AEB2941X carries AEC-Q200 automotive qualification and anti-sulfur coating, identical to the original RG1005P-2941-C-T10. This Panasonic part is approved for automotive-grade applications and meets the same reliability standards.

Q: Can I use RT0402CRD072K94L (YAGEO) in place of the Susumu part?

A: RT0402CRD072K94L is electrically equivalent with matching ±0.25% tolerance and ±25ppm/°C temperature coefficient. However, this YAGEO part does not carry AEC-Q200 automotive qualification or anti-sulfur coating. Use this substitute only in applications where automotive qualification is not required.

Q: What is the advantage of RG1005V-2941-P-T1 over the original part?

A: RG1005V-2941-P-T1 offers superior tolerance (±0.02% versus ±0.25%) and improved temperature stability (±5ppm/°C versus ±25ppm/°C). Both parts maintain AEC-Q200 qualification and anti-sulfur coating. The upgrade is beneficial for precision analog circuits requiring tighter component tolerances and reduced temperature drift.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, standard for automated assembly processes. The original RG1005P-2941-C-T10 was supplied in tube packaging; TR format is functionally equivalent and preferred for high-volume production.

Q: What is the moisture sensitivity level for substitute parts?

A: All substitute parts listed carry MSL 1 (Unlimited) moisture sensitivity rating, identical to the original part. This indicates no moisture bake-out requirement prior to soldering and unlimited shelf life under normal storage conditions.

Q: Can I mix different substitute parts in the same production run?

A: All listed substitutes are mechanically and electrically compatible within the specified tolerance and temperature coefficient ranges. However, for consistency in circuit performance, using a single part number across a production run is recommended to maintain uniform component characteristics.
