Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-681-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 680 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W) minimum
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±0.02%
• Temperature coefficient: May vary within acceptable limits
• Packaging format: Tape & Reel (TR) acceptable as alternative to standard packaging
• Manufacturer: Different manufacturers permitted if all mandatory parameters are met

Substitute parts are classified into two categories: upgrade parts with improved specifications and similar parts with acceptable tolerance relaxation.

Engineering Selection Recommendations

RG2012V-681-P-T1 (Susumu Upgrade)

The RG2012V-681-P-T1 is the primary substitute for the obsolete RG2012N-681-P-T1. This part maintains identical electrical specifications (680 Ohms ±0.02%, 0.125W) and mechanical compatibility (0805 package). The upgrade variant features an improved temperature coefficient of ±5ppm/°C compared to the original ±10ppm/°C, providing enhanced thermal stability. The part is currently in active production status with ROHS3 compliance and AEC-Q200 automotive qualification. Packaging is available in Tape & Reel (TR) format with 987 units in stock.

ERA-6AEB681V (Panasonic Alternative)

The ERA-6AEB681V from Panasonic Electronic Components serves as a secondary substitute option. This part meets all mandatory parameters: 680 Ohms resistance, 0.125W power rating, 0805 package format, -55°C ~ 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. The tolerance specification is ±0.1%, which is relaxed compared to the original ±0.02% but remains within acceptable limits for most applications. The temperature coefficient is ±25ppm/°C. Physical dimensions are identical except for seated height (0.024" vs. 0.020"), which may require verification for space-constrained applications. This part is in active production with 22,242 units available in stock.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-681-P-T1 be used as a direct replacement for RG2012N-681-P-T1?

A: Yes. The RG2012V-681-P-T1 maintains identical electrical and mechanical specifications. Both parts are 680 Ohms ±0.02%, 0.125W, 0805 package, with AEC-Q200 automotive qualification and ROHS3 compliance. The upgrade variant features improved temperature stability (±5ppm/°C vs. ±10ppm/°C).

Q: What is the difference between the Susumu and Panasonic options?

A: The primary difference is tolerance specification. RG2012V-681-P-T1 maintains ±0.02% tolerance matching the original part. ERA-6AEB681V has ±0.1% tolerance, which is relaxed but acceptable for applications not requiring precision matching. Temperature coefficient also differs: ±5ppm/°C (Susumu upgrade) versus ±25ppm/°C (Panasonic). Seated height differs by 0.004" (0.10mm).

Q: Are there packaging format differences between these parts?

A: The RG2012N-681-P-T1 original part does not specify packaging format in the provided data. Both substitute parts are available in Tape & Reel (TR) format. Physical dimensions and footprint are identical for Susumu parts (0.079" L x 0.049" W). The Panasonic part has the same length and width but maximum seated height of 0.024" versus 0.020" for Susumu variants.

Q: Do all parts meet automotive standards?

A: Yes. RG2012N-681-P-T1, RG2012V-681-P-T1, and ERA-6AEB681V all carry AEC-Q200 automotive qualification and are ROHS3 compliant. All parts have Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute should be selected for precision applications?

A: RG2012V-681-P-T1 is the appropriate selection for applications requiring ±0.02% tolerance matching. This part is the direct upgrade from the obsolete original and maintains all precision specifications.

Q: Can ERA-6AEB681V be used in applications requiring ±0.02% tolerance?

A: ERA-6AEB681V has ±0.1% tolerance specification. Selection depends on application tolerance requirements. Applications requiring ±0.02% tolerance must use RG2012V-681-P-T1.
