Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG1005P-9312-B-T5 is determined by the following critical parameters:

Electrical Specifications:

• Resistance value: 93.1 kOhms
• Tolerance: ±0.1%
• Temperature coefficient: ±25ppm/°C

Mechanical Specifications:

• Package type: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of terminations: 2

Compliance & Environmental:

• Composition: Thin Film
• RoHS3 compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range: -55°C minimum to 155°C minimum

Parts meeting all these criteria are classified as direct substitutes. Parts with higher power ratings or extended temperature ranges remain compatible when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

CPF0402B93K1E1 (TE Connectivity Passive Product): This substitute provides electrical and mechanical equivalence to the RG1005P-9312-B-T5. All core specifications including resistance, tolerance, temperature coefficient, and package dimensions are identical. The component is ROHS3 compliant with MSL 1 rating. The seated height is 0.014" (0.35mm), which is lower than the original part at 0.016" (0.40mm). This substitute lacks automotive AEC-Q200 certification; applications requiring automotive qualification should not use this part.

ERA-2AEB9312X (Panasonic Electronic Components): This substitute is electrically and mechanically equivalent to the RG1005P-9312-B-T5 with identical resistance, tolerance, temperature coefficient, and operating temperature range. The component carries automotive AEC-Q200 certification matching the original part. Physical dimensions and seated height are identical. ROHS3 compliance and MSL 1 rating are maintained. This substitute is suitable for applications with automotive qualification requirements.

TNPW040293K1BEED (Vishay Dale): This substitute meets all electrical specifications with 93.1 kOhms resistance, ±0.1% tolerance, and ±25ppm/°C temperature coefficient. The package and physical dimensions are identical to the original part. The power rating is 0.13W, exceeding the original 0.063W specification. The operating temperature range extends to -55°C ~ 175°C, providing wider thermal coverage than the original -55°C ~ 155°C range. Automotive AEC-Q200 certification is present. ROHS3 compliance and MSL 1 rating are maintained. The higher power rating and extended temperature range do not compromise compatibility in applications designed for the original part specifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B93K1E1 be used in automotive applications requiring AEC-Q200 certification?

A: No. The CPF0402B93K1E1 does not carry AEC-Q200 automotive qualification. For automotive applications requiring this certification, use ERA-2AEB9312X or TNPW040293K1BEED.

Q: What is the significance of the height difference between RG1005P-9312-B-T5 (0.016") and CPF0402B93K1E1 (0.014")?

A: The CPF0402B93K1E1 has a lower seated height. In applications with tight vertical clearance constraints, this lower profile may be advantageous. In standard applications, both heights are compatible with 0402 package specifications.

Q: Why does TNPW040293K1BEED have a higher power rating (0.13W) than the original part (0.063W)?

A: The TNPW040293K1BEED is designed with enhanced power dissipation capability. This higher rating does not affect compatibility; the component operates within the original part's power requirements while providing additional thermal margin.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes—CPF0402B93K1E1, ERA-2AEB9312X, and TNPW040293K1BEED—are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Can TNPW040293K1BEED be used in applications with operating temperatures up to 175°C?

A: Yes. The TNPW040293K1BEED operates across -55°C ~ 175°C. Applications requiring operation above 155°C must use this substitute, as the original RG1005P-9312-B-T5 is rated only to 155°C.

Q: Are all substitutes available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts—CPF0402B93K1E1, ERA-2AEB9312X, and TNPW040293K1BEED—are supplied in Tape & Reel packaging.

Q: What is the primary difference between ERA-2AEB9312X and CPF0402B93K1E1?

A: The ERA-2AEB9312X carries automotive AEC-Q200 certification while CPF0402B93K1E1 does not. Both are electrically and mechanically equivalent. Select ERA-2AEB9312X for automotive-qualified applications.
