Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-3480-W-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 348 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum
• Composition: Thin Film
• Automotive qualification: AEC-Q200 required
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: ±0.05% or tighter (±0.02% acceptable as upgrade)
• Temperature coefficient: ±25ppm/°C or better (±10ppm/°C or ±5ppm/°C acceptable as upgrades)
• Operating temperature range: -55°C ~ 155°C or -55°C ~ 125°C (both acceptable)
• Packaging format: Tape & Reel acceptable for direct substitution
• Product status: Active preferred over obsolete

Substitute parts are grouped into two categories: Direct Manufacturer Substitutes (same manufacturer, same electrical specifications) and Upgrade Substitutes (enhanced performance parameters) and Similar Manufacturer Substitutes (alternative manufacturer, equivalent specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Replacement):

RG2012P-3480-W-T5 is the direct equivalent to RG2012P-3480-W-T1. Both parts share identical electrical specifications (348 Ohms, ±0.05% tolerance, ±25ppm/°C temperature coefficient) and mechanical compatibility. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is recommended for direct replacement in production environments.

Upgrade Substitution (Enhanced Performance):

RG2012N-3480-W-T1, RG2012V-3480-P-T1, RG2012V-3480-W-T1, and RG2012V-3480-W-T5 offer improved temperature coefficient performance (±10ppm/°C or ±5ppm/°C) compared to the original specification (±25ppm/°C). RG2012V-3480-P-T1 additionally provides tighter tolerance (±0.02% versus ±0.05%). These parts are suitable for applications requiring enhanced thermal stability and precision. All upgrade substitutes maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Alternative Manufacturer Substitution:

TNPU0805348RAZEN00 (Vishay Dale) provides functional equivalence with identical resistance, tolerance, and temperature coefficient (±5ppm/°C). This part features moisture-resistant coating in addition to anti-sulfur protection. Operating temperature range is -55°C ~ 125°C, which is narrower than the original -55°C ~ 155°C specification. This part is suitable for applications where the reduced upper temperature limit does not conflict with system requirements.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing quality and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-3480-W-T5 be used as a direct replacement for RG2012P-3480-W-T1?

A: Yes. RG2012P-3480-W-T5 is electrically and mechanically identical to RG2012P-3480-W-T1. The only difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete). Both parts have 348 Ohm resistance, ±0.05% tolerance, and ±25ppm/°C temperature coefficient.

Q: What is the difference between the RG2012N and RG2012V series?

A: The RG2012N series has a temperature coefficient of ±10ppm/°C, while the RG2012V series has ±5ppm/°C. Both maintain the same 348 Ohm resistance and ±0.05% tolerance (except RG2012V-3480-P-T1 which has ±0.02%). The RG2012V series provides superior thermal stability.

Q: Is the TNPU0805348RAZEN00 from Vishay Dale fully compatible?

A: The TNPU0805348RAZEN00 is functionally compatible for most applications. It matches the 348 Ohm resistance, ±0.05% tolerance, and ±5ppm/°C temperature coefficient. The operating temperature range is -55°C ~ 125°C, which is 30°C lower at the upper limit compared to the original -55°C ~ 155°C. Verify that your application does not require operation above 125°C.

Q: What does the "T1" and "T5" designation mean in the part number?

A: The "T" suffix indicates tape packaging format. T1 and T5 refer to different tape specifications and reel configurations. Both are Tape & Reel packaging suitable for automated assembly. The specific designation does not affect electrical performance.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, meeting automotive reliability and quality standards equivalent to the original RG2012P-3480-W-T1.

Q: Can I use RG2012V-3480-P-T1 if my design specifies ±0.05% tolerance?

A: Yes. RG2012V-3480-P-T1 has ±0.02% tolerance, which is tighter than the specified ±0.05%. Tighter tolerance is always acceptable as a substitute when the original specification calls for a looser tolerance.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel packaging is designed for automated pick-and-place assembly equipment. Electrically and mechanically, the components are identical. Selection depends on assembly process requirements.
