Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1005R-14R7-D-T10 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 14.7 Ohms
• Package format: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W) minimum
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum
• Number of terminations: 2
• RoHS3 compliance

Allowable Variation Parameters:

• Tolerance: May be equal to or tighter than ±0.5%
• Temperature coefficient: May be equal to or lower than ±100ppm/°C
• Height (seated): Variation acceptable within PCB assembly constraints
• Automotive certification: AEC-Q200 qualification not required for substitution but indicates quality level

The identified substitute part CPF0402B14R7E1 meets all mandatory matching parameters and provides improved electrical characteristics through tighter tolerance and lower temperature coefficient specifications.

Engineering Selection Recommendations

RG1005R-14R7-D-T10 (Primary Selection)

Select this part when automotive AEC-Q200 qualification is a design requirement. The anti-sulfur coating provides enhanced reliability in harsh automotive environments. Product status is active with adequate inventory availability (1118 units in stock).

CPF0402B14R7E1 (Substitute Selection)

This part is suitable as a direct substitute when the primary part is unavailable. The substitute offers superior electrical performance through tighter tolerance (±0.1% versus ±0.5%) and significantly lower temperature coefficient (±25ppm/°C versus ±100ppm/°C). Both parts are ROHS3 compliant and share identical package dimensions and thermal operating range. The substitute part has lower seated height (0.014" versus 0.016"), which may provide marginal benefits in space-constrained applications. Inventory availability for the substitute is 1217 units in stock.

Both parts are classified as active products with equivalent compliance certifications (ROHS3, EAR99, HTSUS 8533.21.0030) and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can CPF0402B14R7E1 be used as a direct replacement for RG1005R-14R7-D-T10?

A: Yes. Both parts share identical resistance value (14.7 Ohms), power rating (0.063W), package format (0402), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute part meets all mandatory electrical and mechanical compatibility requirements for direct substitution.

Q: What are the differences between these two parts?

A: The primary differences are tolerance specification (±0.1% versus ±0.5%), temperature coefficient (±25ppm/°C versus ±100ppm/°C), and seated height (0.014" versus 0.016"). The substitute part provides tighter tolerance and lower temperature coefficient, resulting in improved stability across temperature variations. The height difference is 0.002" (0.05mm), which is negligible for most PCB assembly applications.

Q: Does the substitute part have automotive AEC-Q200 certification?

A: The provided specifications do not indicate AEC-Q200 certification for CPF0402B14R7E1. If automotive AEC-Q200 qualification is a mandatory design requirement, the primary part RG1005R-14R7-D-T10 must be used.

Q: Are both parts RoHS compliant?

A: Yes. Both RG1005R-14R7-D-T10 and CPF0402B14R7E1 are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1).

Q: What is the impact of the tighter tolerance on circuit performance?

A: The substitute part's ±0.1% tolerance provides more precise resistance values compared to the primary part's ±0.5% tolerance. This results in tighter control of circuit parameters and reduced variation across production batches. The lower temperature coefficient (±25ppm/°C) also ensures more stable resistance values across the full operating temperature range (-55°C to 155°C).

Q: Are there any package or footprint differences?

A: No. Both parts use identical 0402 (1005 Metric) package format with matching length and width dimensions (0.039" L x 0.020" W). The seated height difference of 0.002" is within standard PCB assembly tolerances and does not affect footprint compatibility.

Q: What is the inventory status for both parts?

A: RG1005R-14R7-D-T10 has 1118 units in stock. CPF0402B14R7E1 has 1217 units in stock. Both parts are classified as active products.
