910 Ohm 0.5% 1/8W 0805 Chip Resistor Equivalent & Substitute Parts (9T08052A9100DAHFT)

Part Overview

The 9T08052A9100DAHFT is a 910 Ohm ±0.5% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. This part is classified as obsolete and is RoHS non-compliant. Due to its obsolete status and limited availability relative to active alternatives, equivalent substitute parts are necessary for ongoing production and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 9T08052A9100DAHFT is determined by the following mandatory parameters:

• Resistance value: 910 Ohms (exact match required)
• Tolerance: ±0.5% or better (tighter tolerance acceptable)
• Power rating: 0.125W minimum
• Package: 0805 (2012 Metric) form factor
• Composition: Thin film construction
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating temperature range: Must support -55°C ~ 155°C minimum

Two substitute parts meet these criteria. The first is a direct equivalent from the same manufacturer. The second is an upgrade option with enhanced tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

RT0805DRD07910RL is the direct equivalent substitute. It maintains identical electrical specifications (910 Ohms ±0.5%, 0.125W) and physical package dimensions. This part is manufactured by YAGEO, the same supplier as the main part, and carries active product status with ROHS3 compliance. The improved temperature coefficient (±25ppm/°C versus ±100ppm/°C) provides superior stability without introducing compatibility concerns. This part is the primary recommendation for direct replacement.

TNPW0805910RBETA is an upgrade option from Vishay Dale. It provides enhanced tolerance specification (±0.1% versus ±0.5%), which may be beneficial in precision applications. However, the operating temperature range is limited to -55°C ~ 125°C, which does not fully cover the original part's upper temperature specification of 155°C. This part is suitable only for applications where the reduced upper temperature limit is acceptable. The seated height is also reduced to 0.022" (0.55mm), which may require PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD07910RL be used as a direct drop-in replacement for 9T08052A9100DAHFT?

A: Yes. Both parts share identical resistance (910 Ohms), tolerance (±0.5%), power rating (0.125W), package (0805), and physical dimensions. The RT0805DRD07910RL is fully compatible for direct substitution.

Q: What is the difference between the main part and RT0805DRD07910RL?

A: The primary differences are product status (obsolete versus active) and RoHS compliance (non-compliant versus ROHS3 compliant). The RT0805DRD07910RL also features improved temperature coefficient stability (±25ppm/°C versus ±100ppm/°C).

Q: When should TNPW0805910RBETA be selected instead of RT0805DRD07910RL?

A: TNPW0805910RBETA should be selected only when the enhanced tolerance specification (±0.1%) is required for the application and the operating temperature range does not exceed 125°C. The reduced seated height (0.022" versus 0.024") must also be verified against PCB layout constraints.

Q: Are all three parts compatible with the same PCB footprint?

A: The 9T08052A9100DAHFT and RT0805DRD07910RL share identical footprint dimensions and are fully compatible. TNPW0805910RBETA has a reduced seated height (0.022" versus 0.024"), which may require verification but does not prevent footprint compatibility.

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

A: Temperature coefficient indicates resistance value drift with temperature change. The main part exhibits ±100ppm/°C, while both substitutes offer ±25ppm/°C. Lower temperature coefficient values provide greater resistance stability across the operating temperature range, which is beneficial in precision circuits.

Q: Is RoHS compliance a mandatory requirement for substitution?

A: RoHS compliance depends on application and regulatory requirements. RT0805DRD07910RL is ROHS3 compliant, while TNPW0805910RBETA is not. Verify compliance requirements for your specific application before selection.
