Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0712R4L is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 12.4 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Operating Temperature Range: -55°C ~ 155°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (regulatory requirement)

Allowable Variation Parameters:

• Tolerance: May be equal or tighter (±1% or better)
• Power Rating: May be equal or higher (0.125W or greater)
• Temperature Coefficient: May be equal or lower in absolute value (±50ppm/°C or better)

Two substitute parts meet these criteria:

1. RT0805DRE0712R4L (YAGEO) — Upgrade substitute with improved tolerance (±0.5% vs ±1%)
2. 3-1625868-6 (TE Connectivity Passive Product) — Direct substitute with enhanced power rating (0.25W vs 0.125W) and superior tolerance (±0.1% vs ±1%)

Parameter Comparison

Engineering Selection Recommendations

RT0805DRE0712R4L (YAGEO) is suitable for applications requiring improved tolerance performance while maintaining identical power rating and thermal characteristics. This upgrade substitute provides ±0.5% tolerance versus the ±1% of the main part, with no change to physical dimensions or operating specifications. Both components are manufactured by YAGEO and carry Active product status with ROHS3 compliance.

3-1625868-6 (TE Connectivity Passive Product) is suitable for applications requiring enhanced power dissipation capability, superior tolerance accuracy (±0.1%), and improved temperature stability (±25ppm/°C). The increased power rating (0.25W vs 0.125W) provides additional thermal margin. Physical dimensions remain compatible with 0805 package footprints, with maximum seated height of 0.026" (0.65mm) versus 0.024" (0.60mm) for the main part. All components maintain ROHS3 compliance and Active product status.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE0712R4L be used as a direct replacement for RT0805FRE0712R4L?

A: Yes. Both components share identical resistance value (12.4 Ohms), package format (0805), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). The RT0805DRE0712R4L provides tighter tolerance (±0.5% vs ±1%) with no physical or electrical incompatibilities.

Q: What are the physical compatibility considerations for 3-1625868-6?

A: The 3-1625868-6 maintains 0805 package compatibility with identical length and width (0.079" x 0.049"). Maximum seated height is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the main part. This 0.002" (0.05mm) difference is within standard PCB assembly tolerances for 0805 components.

Q: When should 3-1625868-6 be selected over the main part?

A: Select 3-1625868-6 when the application requires higher power dissipation capability (0.25W vs 0.125W), superior tolerance accuracy (±0.1% vs ±1%), or improved temperature coefficient performance (±25ppm/°C vs ±50ppm/°C). All three components are electrically and mechanically compatible within their specified parameters.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT0805FRE0712R4L, RT0805DRE0712R4L, and 3-1625868-6 are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the resistance tolerance impact of substitution?

A: The main part specifies ±1% tolerance. RT0805DRE0712R4L provides ±0.5% tolerance (tighter). 3-1625868-6 provides ±0.1% tolerance (significantly tighter). Tighter tolerance specifications are compatible with applications designed for ±1% components.
