Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1005P-331-W-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 330 Ohms
• Package / Case: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS and REACH compliance status

Variable Parameters Allowing Substitution:

• Tolerance: ±0.05% (main part) to ±0.02% (enhanced alternatives)
• Temperature coefficient: ±25ppm/°C (main part) to ±5ppm/°C (enhanced alternatives)
• Packaging format: Bulk to Tape & Reel (TR)
• Product status: Obsolete to Active

All substitute parts maintain identical mechanical dimensions (0.039" L x 0.020" W, 0.016" max height), termination count (2), and regulatory compliance. Substitutes with improved tolerance and temperature coefficient specifications represent functional upgrades while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

RG1005P-331-W-T5 provides direct substitution with identical electrical specifications (±0.05% tolerance, ±25ppm/°C temperature coefficient). The primary difference is packaging format (Tape & Reel versus bulk), making this suitable for high-volume production environments. Active product status ensures long-term availability.

Enhanced Performance Alternatives:

RG1005N-331-W-T1 offers improved temperature stability (±10ppm/°C versus ±25ppm/°C) while maintaining ±0.05% tolerance. This upgrade is applicable in applications requiring tighter thermal drift control across the full operating temperature range.

RG1005V-331-P-T1 and RG1005V-331-W-T1 represent the highest performance tier with ±0.02% tolerance and ±5ppm/°C temperature coefficient. These components are suitable for precision measurement circuits, reference networks, and applications with stringent accuracy requirements. Both maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

All substitute parts are Active products with confirmed inventory availability, ensuring supply chain continuity for the obsolete RG1005P-331-W-T1.

Frequently Asked Questions (FAQ)

Q: Can RG1005P-331-W-T5 replace RG1005P-331-W-T1 in existing designs?

A: Yes. RG1005P-331-W-T5 is electrically and mechanically identical to RG1005P-331-W-T1. The suffix change (T1 to T5) indicates packaging format transition from bulk to Tape & Reel. Both components have identical resistance (330 Ohms), tolerance (±0.05%), power rating (0.063W), temperature coefficient (±25ppm/°C), and package dimensions (0402 / 1005 Metric).

Q: What is the difference between RG1005N-331-W-T1 and RG1005V-331-W-T1?

A: Both are Active alternatives with improved temperature stability compared to the main part. RG1005N-331-W-T1 has ±10ppm/°C temperature coefficient with ±0.05% tolerance. RG1005V-331-W-T1 has ±5ppm/°C temperature coefficient with ±0.05% tolerance. RG1005V-331-W-T1 provides superior thermal performance for applications requiring minimal resistance drift across temperature extremes.

Q: Is RG1005V-331-P-T1 compatible with designs specified for RG1005P-331-W-T1?

A: Yes. RG1005V-331-P-T1 is mechanically and thermally compatible. It provides enhanced electrical performance with ±0.02% tolerance (versus ±0.05%) and ±5ppm/°C temperature coefficient (versus ±25ppm/°C). The "P" designation indicates a different internal construction variant, but all critical parameters for PCB assembly and circuit operation remain compatible.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. All substitute parts (RG1005P-331-W-T5, RG1005N-331-W-T1, RG1005V-331-P-T1, RG1005V-331-W-T1) carry AEC-Q200 qualification with anti-sulfur coating. They are suitable for automotive and high-reliability applications requiring automotive-grade component certification.

Q: What is the significance of Tape & Reel packaging for these substitutes?

A: Tape & Reel (TR) packaging is standard for automated surface mount assembly processes. All substitute parts are supplied in Tape & Reel format, enabling direct integration into high-volume production workflows. This packaging format does not affect electrical or mechanical performance compared to bulk packaging.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, maintaining full regulatory compliance for European and international markets. Moisture Sensitivity Level (MSL) rating is 1 (Unlimited) for all parts, indicating no moisture-related handling restrictions.
