Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1614968-4 is determined by the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 24 kOhms
• Package / Case: 1206 (3216 Metric)
• Composition: Thin Film
• Tolerance: ±0.1% or tighter
• Operating temperature range: -55°C ~ 155°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Upgrades:

• Power rating: 0.125W (1/8W) original; substitute parts rated 0.25W (1/4W) or higher are acceptable as they provide increased power dissipation capability
• Temperature coefficient: ±25ppm/°C original; substitute parts with lower temperature coefficients (±5ppm/°C, ±10ppm/°C, ±25ppm/°C) are acceptable
• Tolerance: ±0.1% original; substitute parts with tighter tolerances (±0.05%, ±0.02%) are acceptable
• Features: Automotive AEC-Q200 certification and anti-sulfur properties are enhancements that do not affect substitution eligibility

All substitute parts listed are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Equivalent Functionality):

Frequently Asked Questions (FAQ)

Q: Can I use a 0.25W (1/4W) rated resistor as a substitute for the 0.125W (1/8W) original part?

A: Yes. The 0.25W rating represents an upgrade in power dissipation capability. If the original circuit design operates within the 0.125W power budget, a 0.25W rated resistor will function identically while providing additional thermal margin. The higher power rating does not affect electrical performance in the circuit.

Q: What is the significance of the temperature coefficient specification?

A: Temperature coefficient indicates how much the resistance value changes with temperature. The original part has ±25ppm/°C. Substitute parts with lower temperature coefficients (±5ppm/°C, ±10ppm/°C) provide better resistance stability across the operating temperature range. This is critical for precision analog circuits, measurement systems, and applications with wide temperature variations.

Q: Are automotive AEC-Q200 certified parts suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 certification indicates compliance with stringent automotive reliability and quality standards. These parts exceed standard industrial requirements and are fully compatible with non-automotive applications. Their use provides enhanced reliability margins.

Q: What does anti-sulfur protection mean?

A: Anti-sulfur protection prevents degradation of resistor performance in environments with hydrogen sulfide or other sulfur-containing compounds. This feature is beneficial in industrial, petrochemical, and harsh environment applications. For standard indoor or controlled environments, this feature provides no additional benefit but does not negatively impact performance.

Q: Can I substitute a ±0.05% tolerance part for the ±0.1% original?

A: Yes. Tighter tolerance specifications (±0.05%, ±0.02%) represent improved accuracy and are fully compatible with circuits designed for ±0.1% tolerance. The tighter tolerance provides better precision without requiring circuit redesign.

Q: Is the 1206 package dimension identical across all substitute parts?

A: The 1206 (3216 Metric) package designation is standardized. All parts listed use this package. Minor dimensional variations exist within manufacturing tolerances (length 0.120" to 0.126", width 0.061" to 0.063", height 0.020" to 0.028"). These variations are within standard PCB design tolerances and do not affect mechanical or electrical compatibility.

Q: Why is the original TE Connectivity part obsolete?

A: Product obsolescence occurs when manufacturers discontinue production. The substitute parts listed are all active products from established manufacturers, ensuring long-term availability and supply chain continuity.

Q: Which substitute part should I select for a new design?

A: Selection depends on application requirements. For standard industrial applications, ERA-8AEB243V or RT1206BRD0724KL provide direct equivalence. For precision circuits, RG3216V-2402-P-T1 or RG3216V-2402-B-T5 offer superior performance. For automotive applications, any part with AEC-Q200 certification is appropriate.
