Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Würth Elektronik 7471286 is determined by strict equivalence across the following critical parameters:

• Tab Width: 0.205" (5.21mm) — determines mechanical fit with mating connectors
• Tab Thickness: 0.020" (0.51mm) — ensures proper contact pressure and electrical performance
• Gender: Male — defines connector polarity and mating orientation
• Termination Method: Solder — specifies attachment to circuit board
• Mounting Type: Through Hole — establishes PCB assembly compatibility
• Contact Material: Brass — provides electrical conductivity baseline
• Contact Finish: Tin — ensures corrosion resistance and solderability
• Insulation: Non-Insulated — confirms bare terminal design

The Keystone Electronics 1286 meets all substitution criteria across these parameters, establishing direct functional equivalence with the obsolete Würth Elektronik part.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 1286 serves as the direct substitute for the obsolete Würth Elektronik 7471286. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments. The Keystone part carries active product status with UL approval certification, providing long-term availability and supply chain stability compared to the obsolete Würth Elektronik offering.

The tab length variance of 0.005" (0.13mm) between the two parts falls within acceptable mechanical tolerance for quick-connect terminal applications and does not compromise functional compatibility. The Keystone Electronics 1286 is available in bulk packaging with significantly higher inventory levels, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: What makes the Keystone Electronics 1286 a suitable substitute for the Würth Elektronik 7471286?

A: Both components share identical tab width (0.205"), tab thickness (0.020"), overall length (0.500"), gender (male), termination method (solder), mounting type (through hole), contact material (brass), contact finish (tin), and insulation configuration (non-insulated). These parameters define mechanical and electrical compatibility with mating connectors and circuit board assemblies.

Q: Does the 0.005" difference in tab length affect compatibility?

A: No. The tab length variance (0.245" versus 0.250") is within standard mechanical tolerance for quick-connect terminal applications and does not impact mating depth, contact pressure, or electrical performance in standard connector housings.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The Keystone Electronics 1286 includes UL approval certification, providing additional third-party validation for safety-critical applications.

Q: What is the availability difference between these parts?

A: The Würth Elektronik 7471286 is obsolete with limited remaining inventory. The Keystone Electronics 1286 maintains active product status with substantially higher stock levels, ensuring procurement reliability for current and future production runs.

Q: Can I use the Keystone part as a direct drop-in replacement?

A: Yes. The Keystone Electronics 1286 functions as a direct mechanical and electrical substitute. No circuit board redesign or connector housing modification is required for integration into existing assemblies designed for the Würth Elektronik 7471286.
