Substitute Part Grouping Explanation

Substitution of the RG2012P-1651-P-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 1.65 kOhms (exact match required)
• Tolerance: ±0.02% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Physical dimensions: 0.079" L x 0.049" W, 0.020" max height (exact match required)
• Number of terminations: 2 (exact match required)

Compliance & Environmental Parameters:

• Composition: Thin Film (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Anti-sulfur construction (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS3 compliance (exact match required)
• Moisture sensitivity level: 1 (exact match required)

The RG2012V-1651-P-T1 meets all substitution criteria as an active product with identical electrical, mechanical, and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

The RG2012V-1651-P-T1 is the direct functional equivalent and recommended substitute for the obsolete RG2012P-1651-P-T1. Selection is based on the following engineering criteria:

Product Status: The RG2012V-1651-P-T1 maintains active product status with Susumu, ensuring continued availability and manufacturing support. The main part RG2012P-1651-P-T1 is classified as obsolete, creating supply chain risk for ongoing production and field service requirements.

Electrical & Mechanical Equivalence: All critical electrical parameters (resistance, tolerance, power rating) and mechanical specifications (package, dimensions, terminations) are identical between the two parts. Both components are thin film construction with identical operating temperature ranges and identical AEC-Q200 automotive qualification.

Compliance & Certifications: Both parts maintain ROHS3 compliance, identical moisture sensitivity level (MSL 1), and anti-sulfur automotive-grade construction. No compliance gaps exist between the main part and substitute.

Performance Enhancement: The RG2012V-1651-P-T1 provides superior temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), resulting in improved stability across the full operating temperature range while maintaining all other specifications.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. If bulk packaging is required for specific applications, this should be addressed through supplier inquiry.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-1651-P-T1 be used as a direct replacement for RG2012P-1651-P-T1 in existing designs?

A: Yes. The RG2012V-1651-P-T1 is electrically and mechanically identical to the RG2012P-1651-P-T1 across all critical parameters including resistance value, tolerance, power rating, package type, and operating temperature range. Both parts meet AEC-Q200 automotive qualification and ROHS3 compliance requirements. Direct substitution is supported without design modification.

Q: What is the difference between the RG2012P and RG2012V designations?

A: The primary difference is product status and packaging format. The RG2012P-1651-P-T1 is obsolete and supplied in bulk packaging. The RG2012V-1651-P-T1 is an active product supplied in Tape & Reel (TR) format. Both parts share identical electrical and mechanical specifications.

Q: Does the RG2012V-1651-P-T1 have different temperature stability than the main part?

A: The RG2012V-1651-P-T1 has a superior temperature coefficient of ±5ppm/°C compared to ±25ppm/°C for the RG2012P-1651-P-T1. This results in better resistance stability across the -55°C to 155°C operating temperature range. Both parts maintain the same operating temperature limits.

Q: Are there any compatibility issues with PCB assembly when switching to the RG2012V-1651-P-T1?

A: No compatibility issues exist. Both parts use identical 0805 (2012 Metric) package dimensions (0.079" L x 0.049" W, 0.020" max height) with two terminations. PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Is the RG2012V-1651-P-T1 suitable for automotive applications?

A: Yes. The RG2012V-1651-P-T1 carries AEC-Q200 automotive qualification and anti-sulfur construction, identical to the main part. It is approved for automotive-grade applications across the full operating temperature range.

Q: What is the moisture sensitivity level for the RG2012V-1651-P-T1?

A: Both the main part and substitute have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture bake-out requirements. Standard dry storage conditions apply.

Q: Can the RG2012V-1651-P-T1 be ordered in bulk packaging instead of Tape & Reel?

A: The RG2012V-1651-P-T1 is standard supplied in Tape & Reel (TR) format. Packaging format availability should be confirmed directly with the supplier or authorized distributor.
