Substitute Part Grouping Explanation

Substitution of the RG2012N-2103-C-T5 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 210 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• Anti-sulfur construction (exact match required)

Allowable Variation Parameter:

• Tolerance: The main part specifies ±0.25%. Substitute parts with equal or tighter (lower) tolerance values are electrically compatible, as tighter tolerance specifications represent improved performance within the same resistance value and do not violate circuit design requirements.

All identified substitute parts maintain identical electrical and mechanical specifications except for tolerance ratings, which are equal to or tighter than the original specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (RG2012N-2103-B-T5, RG2012N-2103-W-T1, and RG2012N-2103-W-T5) are direct functional equivalents to the obsolete RG2012N-2103-C-T5. Selection among these alternatives is based on the following criteria:

Product Status: All substitute parts carry active product status, ensuring continued availability and manufacturing support. The main part is obsolete and should be replaced in new designs and production runs.

Compliance and Certifications: All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and REACH unaffected status, matching the regulatory requirements of the original part.

Tolerance Specifications: The substitute parts offer improved tolerance performance:

• RG2012N-2103-B-T5 provides ±0.1% tolerance (tighter than the original ±0.25%)
• RG2012N-2103-W-T1 and RG2012N-2103-W-T5 both provide ±0.05% tolerance (significantly tighter than the original ±0.25%)

Tighter tolerance specifications represent enhanced precision and are compatible with all circuit applications designed for the original ±0.25% tolerance specification.

Packaging: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-2103-B-T5, RG2012N-2103-W-T1, or RG2012N-2103-W-T5 be used as direct replacements for RG2012N-2103-C-T5?

A: Yes. All three substitute parts are direct functional equivalents. They maintain identical resistance value (210 kOhms), power rating (0.125W), package type (0805), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The substitute parts feature equal or tighter tolerance specifications, which are compatible with all applications designed for the original part.

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

A: The primary difference is tolerance specification. RG2012N-2103-B-T5 offers ±0.1% tolerance, while RG2012N-2103-W-T1 and RG2012N-2103-W-T5 both offer ±0.05% tolerance. All other electrical and mechanical parameters are identical. The selection between these parts depends on the precision requirements of the specific application.

Q: Are the substitute parts compatible with the original PCB layout and assembly process?

A: Yes. All substitute parts use the identical 0805 (2012 Metric) package with matching dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.020" or 0.50mm). No PCB layout modifications or assembly process changes are required.

Q: Do the substitute parts meet automotive standards?

A: Yes. All substitute parts carry AEC-Q200 qualification and anti-sulfur construction, meeting automotive reliability and environmental requirements equivalent to the original part.

Q: Why is the original RG2012N-2103-C-T5 listed as obsolete?

A: The original part has been discontinued by the manufacturer. The substitute parts represent the current active alternatives that maintain full electrical and mechanical compatibility while providing improved tolerance specifications and continued manufacturing support.

Q: Are there any environmental or compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited). Environmental and regulatory compliance is equivalent across all parts.
