Key Parameters

Substitute Part Grouping Explanation

Substitution of the Keystone Electronics 15405 turret board is determined by strict equivalence across the following critical parameters:

• Number of Positions: 33 positions (fixed requirement)
• Pitch: 0.218" (5.54mm) turret spacing (fixed requirement)
• Terminal Type: Turret, Single End, Single Turret, Hollow (fixed requirement)
• Board Dimensions: 7.687" L x 0.312" W x 0.062" H (fixed requirement)
• Contact Material: Brass (fixed requirement)
• Contact Finish: Tin (fixed requirement)
• Mounting Hole Diameter: 0.067" (1.70mm) (fixed requirement)

The primary distinction between the main part and its substitute is the board substrate material: the 15405 uses XP Phenolic, while the substitute 15505 uses Glass Epoxy. Both materials maintain equivalent electrical and mechanical performance within the specified parameters and meet identical compliance standards.

Parameter Comparison

Engineering Selection Recommendations

The Keystone Electronics 15505 is the direct substitute for the obsolete 15405 turret board. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, terminal configuration, and board dimensions. The 15505 is manufactured from Glass Epoxy substrate material instead of XP Phenolic, a change that does not affect functional compatibility or performance within the specified application envelope.

The 15505 holds active product status with current manufacturing availability (1118 pcs in stock), whereas the 15405 is obsolete. Both parts achieve ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence. The MSL rating of 1 (Unlimited) is maintained across both parts, indicating identical moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 15505 directly replace the 15405 in existing designs?

A: Yes. The 15505 maintains identical electrical and mechanical specifications across all critical parameters: 33 positions, 0.218" pitch, turret terminal configuration, board dimensions, contact material (brass), contact finish (tin), and mounting hole diameter. The substrate material change from XP Phenolic to Glass Epoxy does not affect functional compatibility.

Q: What is the difference between XP Phenolic and Glass Epoxy substrates?

A: Both materials are specified for this turret board application and provide equivalent performance within the defined electrical and mechanical parameters. The substrate material difference does not impact the electrical characteristics, mechanical strength, or reliability of the component in this configuration.

Q: Are there any compliance differences between the 15405 and 15505?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Regulatory and environmental compliance is equivalent.

Q: Why is the 15405 listed as obsolete?

A: The 15405 has been discontinued by the manufacturer. The 15505 represents the current active production equivalent and is the recommended part for new designs and ongoing procurement.

Q: Are the board dimensions identical between both parts?

A: Yes. Both the 15405 and 15505 share identical board dimensions of 7.687" L x 0.312" W x 0.062" H (195.20mm x 7.90mm x 1.57mm) and identical mounting hole diameter of 0.067" (1.70mm), ensuring mechanical interchangeability.
