Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N and RG2012V series parts provide direct electrical and mechanical substitution. All listed alternatives are active products with AEC-Q200 automotive qualification and anti-sulfur construction matching the original specification.

Tolerance Upgrades:

RG2012N-1022-B-T5 and RG2012N-1022-W-T1/W-T5 offer improved tolerance (±0.1% and ±0.05% respectively) while maintaining identical power rating and temperature coefficient.
RG2012V series parts provide superior temperature coefficient performance (±5ppm/°C versus ±10ppm/°C) with equivalent or tighter tolerance specifications.
RG2012V-1022-P-T1 represents the highest precision option at ±0.02% tolerance with ±5ppm/°C temperature coefficient.

Cross-Manufacturer Alternative:

TNPW080510K2BYEA (Vishay Dale) provides functional equivalence with identical resistance and tolerance to RG2012N-1022-B-T5. This part offers increased power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). AEC-Q200 qualification and anti-sulfur construction are maintained.

Selection Criteria:

For direct replacement with improved tolerance: RG2012N-1022-B-T5
For highest precision applications: RG2012V-1022-P-T1

Frequently Asked Questions (FAQ)

Q: Can RG2012N-1022-C-T5 be directly replaced with RG2012N-1022-B-T5?

A: Yes. Both parts share identical resistance (10.2 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RG2012N-1022-B-T5 provides improved tolerance (±0.1% versus ±0.25%) and is an active product, making it a suitable direct replacement.

Q: What is the difference between RG2012N and RG2012V series?

A: The primary difference is temperature coefficient. RG2012N series has ±10ppm/°C while RG2012V series has ±5ppm/°C. Both series maintain identical resistance values, package types, and power ratings. RG2012V provides superior temperature stability.

Q: Is TNPW080510K2BYEA compatible with the original RG2012N-1022-C-T5?

A: Yes, with considerations. TNPW080510K2BYEA maintains identical resistance (10.2 kOhms), package (0805), and tolerance (±0.1%). It provides higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C). Physical dimensions are equivalent. Cross-manufacturer substitution is electrically and mechanically compatible.

Q: Why is the original part obsolete?

A: RG2012N-1022-C-T5 is listed as obsolete. Multiple active alternatives with equivalent or superior specifications are available from the same manufacturer (Susumu) and cross-manufacturer sources (Vishay Dale).

Q: Can I use a part with tighter tolerance than the original specification?

A: Yes. Parts with tighter tolerance (lower percentage value) are acceptable substitutes. For example, RG2012N-1022-W-T1 at ±0.05% tolerance can replace the original ±0.25% specification without circuit redesign.

Q: What packaging options are available for these substitutes?

A: All listed substitute parts are supplied in Tape & Reel (TR) packaging, consistent with the original component packaging format.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts maintain AEC-Q200 automotive qualification and anti-sulfur construction, meeting the original component's reliability and compliance requirements.
