Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1005P-1240-W-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 124 Ohms
• Package / Case: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±0.05% or better)
• Temperature coefficient: May be equal or lower (±25ppm/°C or better)
• Packaging format: Tape & Reel (TR) acceptable as functional equivalent
• Product status: Active status preferred for obsolete parts

All substitute parts listed maintain identical electrical performance for the specified 124 Ohm resistance value and mechanical compatibility within the 0402 package footprint.

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Equivalent: RG1005P-1240-W-T5 provides identical electrical specifications to the main part with the same tolerance (±0.05%) and temperature coefficient (±25ppm/°C). The primary difference is packaging format (Tape & Reel) and active product status. This part is suitable for direct substitution in applications where the original packaging format is not a constraint.

Enhanced Performance Alternatives: RG1005N-1240-W-T1 and RG1005V-1240-W-T1 offer improved temperature coefficient performance (±10ppm/°C and ±5ppm/°C respectively) while maintaining the ±0.05% tolerance. These parts provide superior temperature stability across the full operating range and are recommended for precision applications requiring enhanced thermal performance.

Premium Precision Option: RG1005V-1240-P-T1 delivers the tightest tolerance specification (±0.02%) combined with the lowest temperature coefficient (±5ppm/°C). This part is suitable for applications requiring maximum precision and minimal drift characteristics. All substitute parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can RG1005P-1240-W-T5 replace RG1005P-1240-W-T1 directly? A: Yes. Both parts share identical electrical specifications (124 Ohms, ±0.05% tolerance, ±25ppm/°C temperature coefficient, 0.063W power rating). The primary difference is packaging format. RG1005P-1240-W-T5 is supplied in Tape & Reel format and has active product status.

Q: What is the difference between RG1005N-1240-W-T1 and RG1005V-1240-W-T1? A: Both parts maintain the same 124 Ohm resistance and ±0.05% tolerance. The RG1005N-1240-W-T1 has a temperature coefficient of ±10ppm/°C, while the RG1005V-1240-W-T1 has ±5ppm/°C. The RG1005V variant provides superior temperature stability.

Q: Is RG1005V-1240-P-T1 compatible with the original part footprint? A: Yes. The RG1005V-1240-P-T1 maintains the identical 0402 (1005 Metric) package dimensions and footprint. The "P" designation indicates a different tolerance specification (±0.02% versus ±0.05%), not a physical size change.

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. All listed substitute parts carry automotive AEC-Q200 qualification and anti-sulfur construction, matching the original part's automotive-grade specifications.

Q: What is the significance of the temperature coefficient differences? A: Temperature coefficient indicates resistance value drift per degree Celsius. Lower values (±5ppm/°C) provide better stability across temperature extremes. For applications operating across the full -55°C to 155°C range, lower temperature coefficients reduce resistance variation.

Q: Can I use RG1005V-1240-P-T1 in place of RG1005P-1240-W-T1? A: Yes. The RG1005V-1240-P-T1 is a functional upgrade offering tighter tolerance (±0.02% versus ±0.05%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). It is electrically and mechanically compatible with identical package dimensions and operating temperature range.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of the original part.
