Substitute Part Grouping Explanation

Substitution of the RG2012N-681-B-T5 is permissible with parts that maintain identical electrical and mechanical specifications across the following critical parameters:

• Resistance value: 680 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or greater acceptable)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C or better (equal or tighter acceptable)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• Automotive qualification: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 Compliant (required)

Tolerance specifications may be tightened (reduced) without affecting substitution validity, as tighter tolerances represent enhanced performance. The identified substitute part RG2012N-681-W-T1 meets all substitution criteria with an improved tolerance specification of ±0.05%.

Parameter Comparison

Engineering Selection Recommendations

The RG2012N-681-W-T1 is a direct substitute for the RG2012N-681-B-T5 with enhanced tolerance specification. Both parts are manufactured by Susumu, carry active product status, and maintain full compliance with ROHS3 and AEC-Q200 automotive standards. The substitute part features ±0.05% tolerance compared to the main part's ±0.1% tolerance, providing improved precision for applications requiring tighter resistance accuracy. Both parts are packaged identically in 0805 (2012 Metric) format with identical physical dimensions and thermal characteristics. Selection between these parts depends on application tolerance requirements and inventory availability. The substitute part is suitable for all applications where the main part is specified, with the added benefit of enhanced tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-681-W-T1 be used as a direct replacement for RG2012N-681-B-T5?

A: Yes. The RG2012N-681-W-T1 is a direct substitute. Both parts share identical resistance value (680 Ohms), package type (0805), power rating (0.125W), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The substitute features improved tolerance (±0.05% versus ±0.1%), which enhances precision without affecting compatibility.

Q: Are there any physical differences between these parts?

A: No. Both parts have identical physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm). They are both packaged in 0805 (2012 Metric) format and are footprint-compatible on PCBs.

Q: Do both parts meet automotive standards?

A: Yes. Both RG2012N-681-B-T5 and RG2012N-681-W-T1 carry AEC-Q200 automotive qualification and are anti-sulfur rated, making them suitable for automotive applications.

Q: What is the difference in tolerance between these parts?

A: The main part RG2012N-681-B-T5 has ±0.1% tolerance, while the substitute RG2012N-681-W-T1 has ±0.05% tolerance. The substitute provides tighter tolerance, resulting in more precise resistance values. This is an improvement that does not compromise compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

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

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts are electrically and mechanically compatible and can be used interchangeably. The substitute part's improved tolerance specification makes it suitable for all applications where the main part is specified.
