Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG1005N-1402-C-T10 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 14 kOhms
• Package type: 0402 (1005 Metric)
• Power rating: 0.063W (1/16W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C

Allowable Variation Parameters:

• Tolerance: Substitute parts with equal or tighter (lower) tolerance values are acceptable
• Automotive rating: AEC-Q200 certification is maintained across all substitutes
• Manufacturer: Different manufacturers are acceptable provided all critical parameters align

The substitute parts listed below meet or exceed the electrical and mechanical specifications of the main part while offering active product status and improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu Series):

RG1005N-1402-B-T5 and RG1005N-1402-W-T1 are direct substitutes manufactured by Susumu. Both parts maintain the same package, power rating, composition, and temperature characteristics as the main part. The key distinction is tolerance specification: RG1005N-1402-B-T5 offers ±0.1% tolerance, while RG1005N-1402-W-T1 provides ±0.05% tolerance. Both parts carry active product status and AEC-Q200 automotive qualification, making them suitable for applications requiring automotive-grade reliability. Selection between these two should be based on circuit tolerance requirements.

Alternative Substitute (Cross-Manufacturer):

RN73C1E14KBTDF manufactured by TE Connectivity Passive Product is a cross-manufacturer substitute that matches all critical electrical parameters. This part maintains ±10ppm/°C temperature coefficient and -55°C ~ 155°C operating range. The seated height is 0.014" (0.35mm), which is lower than the main part and Susumu substitutes at 0.016" (0.40mm). This component carries active product status and ROHS3 compliance. AEC-Q200 automotive rating is not specified for this part.

Selection Criteria:

For applications requiring AEC-Q200 automotive qualification, RG1005N-1402-B-T5 or RG1005N-1402-W-T1 are the appropriate selections. For applications where automotive qualification is not mandatory, RN73C1E14KBTDF provides an active alternative with equivalent electrical performance. Tolerance selection should align with circuit design requirements: ±0.25% tolerance (original specification) is maintained by RG1005N-1402-B-T5 at ±0.1%, and RG1005N-1402-W-T1 at ±0.05% provides enhanced precision.

Frequently Asked Questions (FAQ)

Q: Can RG1005N-1402-B-T5 be used as a direct replacement for RG1005N-1402-C-T10?

A: Yes. RG1005N-1402-B-T5 is a direct substitute. Both parts share identical resistance value (14 kOhms), package (0402), power rating (0.063W), composition (thin film), and temperature characteristics. The substitute offers improved tolerance (±0.1% versus ±0.25%) and active product status. Both carry AEC-Q200 automotive qualification.

Q: What is the difference between RG1005N-1402-B-T5 and RG1005N-1402-W-T1?

A: Both parts are Susumu 14 kOhms 0402 thin film resistors with identical electrical and mechanical specifications except for tolerance. RG1005N-1402-B-T5 specifies ±0.1% tolerance, while RG1005N-1402-W-T1 specifies ±0.05% tolerance. Selection depends on circuit tolerance requirements. Both are active products with AEC-Q200 qualification.

Q: Is RN73C1E14KBTDF suitable for automotive applications?

A: RN73C1E14KBTDF meets all electrical specifications for automotive use (14 kOhms, ±10ppm/°C, -55°C ~ 155°C operating range). However, AEC-Q200 automotive qualification is not specified for this part. For applications requiring explicit AEC-Q200 certification, Susumu RG series substitutes (RG1005N-1402-B-T5 or RG1005N-1402-W-T1) are recommended.

Q: Will the lower seated height of RN73C1E14KBTDF (0.014" versus 0.016") affect PCB assembly?

A: The 0.002" (0.05mm) height difference is within typical PCB assembly tolerances. RN73C1E14KBTDF will not interfere with standard 0402 package placement. However, if PCB design includes height-critical constraints, this difference should be evaluated against specific assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RG1005N-1402-B-T5, RG1005N-1402-W-T1, and RN73C1E14KBTDF are all ROHS3 compliant, matching the compliance status of the main part RG1005N-1402-C-T10.

Q: Can I use a substitute with tighter tolerance than the original specification?

A: Yes. Substitutes with equal or tighter tolerance are acceptable. RG1005N-1402-B-T5 (±0.1%) and RG1005N-1402-W-T1 (±0.05%) both offer tighter tolerance than the original ±0.25% specification and will function correctly in circuits designed for the original part.

Q: What is the primary reason for substitution?

A: The RG1005N-1402-C-T10 is classified as obsolete. Active substitute parts ensure continued component availability for new designs and production runs. All listed substitutes maintain electrical and mechanical compatibility while offering active product status.
