Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-2490-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 249 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur construction

Allowable Variation Parameters:

• Tolerance: Substitute parts with equal or tighter tolerance specifications (±0.25%, ±0.1%, ±0.05%, ±0.02%) are electrically compatible
• Product status: Active alternatives are preferred over obsolete status
• Packaging format: Tape & Reel (TR) is compatible with the original packaging specification

All identified substitute parts maintain identical mechanical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and electrical characteristics except for tolerance specifications, which are tighter in all substitute options.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All four substitute parts are direct functional equivalents to the RG2012V-2490-C-T5. Selection among alternatives is based on tolerance requirements and product availability:

RG2012V-2490-W-T5 (±0.05% tolerance, 751 units in stock) provides a balanced upgrade with tighter tolerance specification and active product status. This part maintains the same tape & reel packaging format and offers improved accuracy over the original ±0.25% specification.

RG2012V-2490-W-T1 (±0.05% tolerance, 1150 units in stock) offers the highest inventory availability with identical tolerance performance to RG2012V-2490-W-T5, differing only in tape configuration.

RG2012V-2490-B-T5 (±0.1% tolerance, 963 units in stock) provides a mid-range tolerance upgrade suitable for applications requiring improved accuracy without the cost premium of tighter specifications.

RG2012V-2490-P-T1 (±0.02% tolerance, 894 units in stock) delivers the highest precision option for applications demanding maximum accuracy and stability.

All substitute parts maintain full compliance with AEC-Q200 automotive qualification, ROHS3 environmental standards, and anti-sulfur construction specifications. Mechanical compatibility is assured across all alternatives, with identical package dimensions and mounting characteristics.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-2490-C-T5 be directly replaced with any of the substitute parts?

A: Yes. All substitute parts maintain identical resistance value (249 Ohms), package format (0805/2012 Metric), power rating (0.125W), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The substitute parts feature tighter tolerance specifications, which are electrically compatible with the original design.

Q: What is the primary difference between the substitute parts?

A: The substitute parts differ in tolerance specification and product status. RG2012V-2490-B-T5 offers ±0.1% tolerance, RG2012V-2490-W-T1 and RG2012V-2490-W-T5 offer ±0.05% tolerance, and RG2012V-2490-P-T1 offers ±0.02% tolerance. All are active products, whereas the original RG2012V-2490-C-T5 is obsolete.

Q: Are there packaging differences between the substitute parts?

A: The substitute parts are supplied in Tape & Reel (TR) packaging format. RG2012V-2490-B-T5, RG2012V-2490-P-T1, RG2012V-2490-W-T1, and RG2012V-2490-W-T5 all use standard tape & reel configuration suitable for automated assembly processes.

Q: Do all substitute parts meet automotive specifications?

A: Yes. All substitute parts carry AEC-Q200 qualification, anti-sulfur construction, ROHS3 compliance, and identical operating temperature range (-55°C ~ 155°C). They are fully qualified for automotive applications.

Q: Which substitute part should be selected for cost-sensitive applications?

A: RG2012V-2490-B-T5 (±0.1% tolerance) provides the most economical upgrade path while maintaining active product status and improved accuracy over the original ±0.25% specification.

Q: Which substitute part offers the best accuracy?

A: RG2012V-2490-P-T1 (±0.02% tolerance) delivers the highest precision specification among all available substitutes, suitable for precision measurement and calibration circuits.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts, including the original RG2012V-2490-C-T5 and all substitutes, share identical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm). PCB footprint compatibility is assured.
